Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to can manufacturing, and more particularly to an improved forming press for manufacturing seamless can bodies.

Although this invention is particularly suited for manufacturing seamless can bodies from metals such as aluminum, steel, etc., and will be specifically described in that regard, the invention is more broadly applicable and can be made from a variety of materials. It can be used to produce seamless cans or similar products.
As is known in the art, seamless can bodies are manufactured by pressing a circular metal hollow body deep into a cup-shaped member and then pressing again to lengthen and thin the metal sidewall to the desired diameter. Ru. - In general, the bottom of the hollow body is bulged into a hemispherical shape on the inside of the side wall in all directions, and the side wall is trimmed to the desired shape to produce a can body having a predetermined finished size and shape. Various machines have been designed for use in rolling and hemispherically forming seamless cans in the manner described above. Generally, such devices have a frame that supports at least one punch or punches for horizontal movement along a straight path between the first and second steps. The one or more rolling rings are supported between the first and second steps by a frame of the interlocking passage of the punch.

The can hollow body guided thereby to the end of the punch moves through the rolling ring during the movement of the punch from the first position to the second position in order to effect rolling of the side of the hollow body. do. Such devices generally include a hemispherical inflating device, the counterfeit of which is aligned with the punch and supported by a frame to act on the punch and the can hollow body when the punch reaches a second position. . Attach a hemispherical shape.Fold down the Hishitaka and punch together to inflate the end wall of the can hollow body into a hemispherical shape. Following that operation, the punch returns to the first orientation, the can hollow body is peeled off from the punch during a first return movement, and the forming can is then removed from the loading. The present invention relates to a rolling machine having the above-mentioned characteristics, in which certain working components of the rolling stock are horizontal can rolling which improve operation, facilitate assembly and adjustment, extend service life and further increase operating efficiency. We provide counterfeit press bags.

To describe the features of the present invention in more detail, the horizontal can rolling press includes a slide supported in a reciprocating manner by a press frame, and one or more pumps are connected to the frame to move first and second positions. Move at the same time in the darkness.

The frame has groove-shaped cross-section shibs facing each other on the sides to receive the square-section guide ratchets attached to the sides of the slide. Preferably, a slide guide twill extends from the entire length of each guide bar and is reciprocably supported by a bearing block attached to the frame. The channel-shaped jib and guide ram provide a simplified support bearing means for the slide. The slide guide rods then add the desired stability and support to the slide during reciprocating movement, especially during the interaction of the punch and can hollow body off the rolling ring. Another feature of the hakama of the present invention is that it can be freely attached to one or more reciprocating press slides of a rolling press in a manner that is easy to assemble and disassemble.

In this regard, the slider is provided with a rotatable punch connecting member, and the three corresponding parts of the connecting member and the punch are provided with engaging screws that are engaged with each other. The connecting members on the slide rotate in unison with each other, and can be screwed into or released. In a preferred embodiment, rotation of the coupling member is provided by drive gear means including a drive shaft projecting from the slide and rotatable by a crank or the like. The punch can thereby be quickly assembled or released from the slide to facilitate maintenance or replacement operations. According to a further feature of the invention, a device for forming a hemispherical surface is provided for each punch of the rolling press and is supported in an engageable position by the punch and the can hollow body following the rolling operation. .

The hemispherical rhombus is mounted on a horizontal support extending laterally of the punch ball, and one end of the support is rotatable about a vertical axis and continuous with the frame. The other end of the support member is releasably attached to the frame for supporting the hemispherical bag counterfeit in its cutting position with respect to the punch. By disengaging the fastening end of the support, the fastening end can swing horizontally to one side of the frame. Therefore, the hemispherical surface forming device can quickly respond to maintenance and inspection. Yet another feature of the invention is the provision of a rolling press having a pocket delivery wheel supported by a frame for rotation about a horizontal axis.

The wheel extends axially over the rolling ring of the press and provides a pocket for receiving the forming can hollow body as the two punches move back from the extended position to the retracted position. In this regard, the delivery wheel should be
The file is placed so that the empty pockets are aligned in a straight line on the punch material. At the completion of the rolling operation, the punch material returns to its reduced position, and during the first return movement the forming can hollow body is detached from the plunger and ejected into the pocket of the delivery wheel. The delivery wheel then moves the forming can hollow body along the delivery path and repositions the other pair of pockets relative to the punch material. The delivery wheel is driven by the main drive machine for the machine to match the reciprocation of the punch and eject the wheel. The take-off delivery wheel provides a fundamental simplicity and efficiency in operation and allows desired adjustments to be made in the delivery of the forming can hollow bodies from the machine. Therefore, the main object of the present invention is to provide a horizontal can rolling press machine having the above-mentioned characteristics.

Another object is to provide a horizontal can rolling press that facilitates assembly, disassembly, and adjustment processes and reduces the time required for these processes.

Still another object of the present invention is to provide a horizontal can rolling press having a slide and a slide support for reciprocatingly supporting a slide and a punch in relation to a press frame. Yet another object is to provide a press bag stand of the character described above having improved means for removably mounting the punch member on the slide.

Yet another object has an improved support structure for a hemisphere forming device, whereby the hemisphere forming bag is rotated from an operative position to an inactive position with respect to a corresponding punch in relation to a frame. It is an object of the present invention to provide a horizontal can rolling press apparatus which is movably and removably supported.

Yet another object is to provide a horizontal can roll press bag straight with improved means for ejecting formed can hollows.

Still another object is to provide a horizontal can rolling press that is easy to assemble, efficient, durable, and capable of producing can bodies at high speed.

The following will explain the embodiments shown in the drawings.

The punch slide bag hawk C can be reciprocated with respect to the rolling ring bag counterfeit ○ and the hemispherical surface forming device E. The cup-shaped metal can hollow body is fed to the punch member of the punch-slide assembly C by a feed straight line F located between the punch-slide assembly C and the rolling ring assembly ○. The hollow body is fed in synchronization with the reciprocation of the punch slide device. The rolling ring device D and the bottom forming rhombus E' each serve to lengthen the side walls of the can hollow body and bulge the bottom into a hemispherical shape in order to form the can with the desired finished shape. The forming can body is ejected by a take-off delivery diamond pupil G located below the movement path of the punch material and between the rolling ring bag straight D and the bottom forming device E.

One end of the crankshaft extends through the armrest 10 and the bearing lozenge 52 supported thereby, and is connected to a drive motor 401 by a suitable inorganic belt 56. The flywheel is provided on the outside of the frame. Therefore, the rotation of the output shaft of the motor 40 causes the flywheel 54 to rotate, thereby rotating the crank member 44. The other end of the crankshaft extends through the wall 20 and a suitable bearing arrangement 58 supported thereby and is connected through an inorganic belt 60 to a pulley 62 fixed on the input force axis of the gearbox 64. The gear box 64 has an output shaft 66 that drives the forming can delivery device G as described in detail below. Further, a separate power source synchronized with the rotation of the crankshaft may be used to operate the feeding device for feeding the can hollow body to the press. The crank member 44 includes a pair of crank arms 68 in which one end of a connecting hakama 70 and an outer woven part are rotatably connected. is concave, and a concave coupling gap 72 is disposed at the end of the coupling birch to move and receive a crank pin 74 therewith.

As shown in more detail in FIG. 3, the other side of the connecting shank 70 is provided with a hole 78 consisting of a suitable bushing 80 for receiving a piston pin 82 connected at both ends to the slide member.
From the above, when the crank member 44 rotates around the ball 46, the crank member moves to the first position corresponding to the stroke machine section.
It is clear that the punch-slide device C is provided with a reciprocating movement in relation to the frame between and the second counterfeit.

The cross plate 28 is provided with a suitable bead 77 through which the connecting bar 70 extends. The pin 82 has a horizontal axis 84 about which a corresponding portion of the connecting rod 70 rotates during reciprocating movement of the punch-slide device. The horizontal shaft 84 and the crankshaft 46 are on the same horizontal plane. Slide Punch Device C Slide punch device C and its parts are shown in FIGS. 3 to 6.

Referring first to FIGS. 3 and 4, mounting C includes a slide indicated at 86 and a pair of punches 88. Pong 88 is removably mounted on the slide as described in more detail below.
The slide 86 has a top portion including a top plate 90 and a bottom plate 92, and the bottom plates 90 and 92 are spaced apart and connected in parallel by a lip 94 extending vertically.
The ribs 94 are spaced a certain distance inward from the corresponding side weave portions of the plates 90, 92, and are temporarily continuous by sliding by welding or the like. The slide 86 further includes the top and bottom plates 9
0.92 and includes a vertical front plate 96 that extends across the front end of the 0.92 and is connected by welding or the like. The slide structure thus defined further includes upper and lower gusset plates 98 welded to the front plate 96 and top and lower plates 90.9.
Reinforced by the corresponding 1 of 2. Each side of the slide 86 is provided with a guide rod 100 having coaxial first and second portions 102, 104.

The interior portion of the first portion 102 is disposed along corresponding sides of the slide in the recess defined by the ribs 94 and the top and bottom plates 90,92. The guide rod includes, for example, a plurality of bolts 106 extending through the top and bottom plates 90, 92 to threaded holes in the first portion 102 of the guide rod, and through holes in the first portion 102 of the guide rod. It is secured to the slide by inwardly extending bolts 108 that extend into the threaded holes. The first portion 102 of the guide rod has a rectangular cross section and has bearing surfaces formed on its sides.

As shown in the drawing, the bearing surface has upper and lower bronze bearing wear pieces 110 and 122 and outer bronze bearing wear piece 1.

The outer surfaces of wear pieces 110, 112 provide vertically spaced parallel guiding surfaces for sliding, and wear pieces 1
The outer surface of 14 provides a guiding surface perpendicular to the plane of the upper and lower guiding surfaces. The first part 102 of the guide bar and the slide 86
is supported relative to the frame by a corresponding support and guide device 116 mounted on the frame.

Each support guide device includes a horizontally extending support ramp 118 that is secured to the corresponding frame wall, such as by welding, along with a support gusset plate 120. The support guide device further includes an L-shaped jib member 1
22 includes an upper jib 124, the jib members together defining a C-shaped guide structure or groove opening toward the slide 86. The upper jib member 124 is attached to the L-shaped jib member 1 by bolts 126 etc.
22, the L-shaped zip material 122 is secured to the support plate 118 by corresponding bolts 128, 130, etc.
It can be properly fixed. Additionally, an outwardly extending stud 132 is provided on the upright portion of the L-shaped zip material 122, and the stud 132 is screwed into a threaded groove at its inner end. The outer end of the stud 132 passes through an opening in the side wall of the frame to receive a nut 134. Thereby, the jib members 122, 124 are more firmly connected to the frame. The zip members 122, 124 are formed coextensive with the support plate 118 below them to be equal in length to the frame corresponding to the travel of the slide 86 defined by the movement of the crank 44.

Furthermore, the inner surface of the upper jib member 124 and the bottom of the L-shaped jib member 122 define vertically spaced parallel planes that are slidably engaged by a corresponding one of the wear tabs 110,112. The inner surface of the upright portion of the zip material 122 then defines a vertical plane that is slidably engaged by the wear piece 114; The crankshaft 46 and the shaft 84, which provide a rotatable connection between the rod 70 and the slide 86, are coplanar. A second portion 104 of the guide rod is important along with a corresponding first portion 102 and extends forward of the slide 86 beyond the cross plate 26 of the frame.

The intersecting plate 26 has the adjacent weave of the slide 86 line segment 138.
When placed at the end of a forward stroke as shown in , it is located immediately in front of its adjacent end. Second part of guide 104
preferably has a circular cross section, and the cross plate 26 has a sekiguchi 140 through which the front free machine of the second member 104 of the guide rod extends.
is provided. Further, the sliding comb bearing block 142 is attached to the front side of the cross plate 26 by bolts 144 or the like, and is further provided with a suitable bearing sleeve 146 for slidably supporting and receiving the second member 104. The bottom forming bag direct attachment plate 148 is attached to the end plate 22 of the frame A by bolts 150 (see FIG. 1) for the purpose described below. The upper end of the mounting plate 148 is connected to the cross plate 26 by two corresponding pairs of support rods 152. The internal combustion rod 152 is machined into a male thread and is screwed into the threaded hole of the cross plate 26, and its outer end extends through the mounting plate 148, and the nut 154
tightened by. Guide twill part 104 from dirt etc.
To protect the mounting plate 148 and bearing block 14
A slide rod cover 156 is provided between the two ends of the slide rod cover 156, and is fixed by engaging corresponding grooves in the mounting plate and the bearing block at both ends thereof. During the reciprocating movement of the slide 86, the second portion 104 of the guide rod absorbs the effects of lateral and vertical thrusts due to crank movement and forces acting on the slide as a result of the movement of the punch and can hollow bodies across the rolling ring. Stabilize the sliding movement as a minimum. Punch material 88 extends forwardly from front wall 96 of slide 86 through a corresponding entrance 158 in cross plate 26 of frame A.

A corresponding punch rod bearing block plate 160 is attached to the front side of the cross plate 26 by bolts 162 or the like, and is provided with an appropriate push 164 for guiding and supporting the punch that reciprocates in response to the reciprocation of the slide 86. . When the slide is at the rear end of its travel, as indicated by the solid line position in FIG. . The can hollow bodies are fed onto the punch in a preferred manner, for example by hand or by means of a suitable feed mechanism. When its free end is located at the supply station, the feeding operation is carried out in synchronization with the slide reciprocation to position the can hollow body on the punch rod. Since the manner in which the can hollow body is fed onto the punch does not form part of this invention, the mochi polishing mechanism is only schematically illustrated. As previously mentioned, punch rod 88 is removably mounted on slide 86.

This mechanism will become clearer with reference to FIGS. 5 and 6 in conjunction with FIGS. 3 and 4. The slide 86 is provided with a punch removal device 166 for each of the punches 88. Since both the punch 88 and the punch-removal bag holder 166 have similar structures, one of the punches 88 and the punch-removal bag holder connected thereto will be described. The end of the punch 88 that engages with the slide has a terminal core 1 that is externally threaded.
68 and a cylindrical section ITO coaxially adjacent thereto and spaced from the body of the punch by a tapered peripheral flange.

Its purpose is described below. Slide 86 is provided with a support block 174 between top and bottom plates 90,92. Support block 174' is welded or bolted to the front plate 96 and rear slide plate of the slide. The front plate 96 and the block 174 are provided with a stop that extends in the direction of the punch and receives the punch holding sleeve 176. Sleeve 176 has an internal hole formed therein to slidably receive core 170 and to rotatably support driven sleeve 178 . Sleeve 178 is externally threaded for engagement with externally externally threaded punch core 168. The retaining sleeve 176 is held in place on the slide by a plurality of bolts 180 extending toward the front plate 96 of the slide.

The rotatable sleeve 178 has a core 182 at its inner end, and a suitable sleeve bearing 184 is interposed between the core 182 and the hole in the block 174. Worm gear 186
is attached to the core 182 by bolts 188 and rotates the sleeve 178 relative to the retaining sleeve 176.
In this regard, the top plate 90 of the slide 86 and the block 174 are provided with a vertical cutout 190 that abuts the cutout that receives the sleeve 176.178. The lower end of the shaft 192 is rotatably supported by a flange-type bearing sleeve 196, and the upper end of the shaft 192 is rotatably supported by a sleeve bearing 198. A bearing 198 extends from the worm 194 into a groove in a worm shaft retaining plate 200, which is secured to the orientation layer of the top plate 90 of the slide by bolts 202. Warm 19
4 meshes with the worm gear 186, and the outer end of the worm shaft 192 extends upward from the slide and has a square cross section to receive a tool rotating the worm shaft. Rotation of worm shaft 192 and worm 194 causes worm gear 186 and sleeve IT8 to rotate with respect to sleeve 176.

By appropriately supporting punch 88 against rotation relative to sleeve 176, rotation of sleeve 178 allows the punch to be attached to and removed from sleeve 188. The punch may be held in the hand or a suitable retainer (not shown) may be provided in conjunction with the punch support device 160 to clamp the punch and restrict its rotation during punch removal or insertion operations. A suitable tool, such as a hand crank or an air-driven wrench, is used to obtain rotation of the worm shaft 192. During the punch insertion operation, the punch core 150 and fielding sleeve 176 are coaxially coupled to the guiding movement of the punch attachment weave toward the sleeve.

Additionally, the tipper washer 204 cooperates with the tipper flange 172 of the punch to properly orient the punch shaft with respect to the slide path. A horizontal line intersecting the longitudinal axis of punch 0 at this point is coplanar with line 136 mentioned above;
Therefore, it should be noted that the axis 84 of the connecting twill pin 82 and the axis of the crank pin 74 are on the same plane. Furthermore, sleeve 17
Although FIG. 8 has been described as having a female thread on the inside of the punch to receive a male-threaded end portion 168 on the outside of the punch, this configuration can also be reversed. Furthermore, it is also readily possible to rotate the threaded material of the slide in relation to the punch to achieve threaded engagement and disengagement by means other than the specific means shown and described herein. Rolling Ring Apparatus As shown in FIGS. 2 and 3, the rolling ring apparatus 0 consists of a pair of rolling apparatuses 2150 and 212 supported by a frame in line with the movement path of a corresponding punch 88.

The structure of the rolling units 210, 212 and the machinery mounted on the frame A thereof are similar. Accordingly, one of the devices, namely bag straightener 210, will be described in detail. As can be seen in FIGS. 7-12, the rolling ring assembly 210 includes a leg plate 214 disposed on a bolster plate 215 mounted on a horizontal frame plate 30. As shown in FIGS.

A plurality of rolling ring support blocks 216, 218, 220
, 222 are attached to the leg plate 214 by bolts 224 or the like that pass through the leg plate 214 and reach corresponding threaded grooves at the bottom of the support block. The support blocks are axially spaced apart in the direction of punch movement to receive the rolling ring therebetween. The number of support blocks depends on the desired number of rolling operations. In the embodiment shown in FIG.
We accept and support it. Each rolling ring is annular Iso Chengdu material with an integral rolling mirror on its inner periphery cooperating with a punch.

Thereby, when the punch passes through the ring, it rolls the sides around the can hollow body on the punch. As is well known, preferred rolling techniques provide for smaller rolling ring diameters than the ring techniques described above. The rolling ring is rigidly fixed between both sides of the support block and is slidable relative thereto to allow displacement during adjustment operations. The cover block 232 is mounted on the support block and is rotatably coupled directly along one longitudinal edge of the block. As can be seen in Figure 9, the inner longitudinal ends of blocks 218, 222 and the corresponding ends of cover block 232 are provided with hinge devices, one of which is bolted or attached to a corresponding mounting block. It has a pair of striped hinge plates that are rotatable about a hinge pin 236 therebetween, so that the cover 232 can be rotated upwardly and clockwise relative to the mounting block as shown in FIG. The cover 232 is loosely maintained in a closed position on the mounting block by a pair of rotatable clamps 238, and a clamping device is mounted along the exterior longitudinal edges of the mounting block and cover. It is arranged as follows.

Each device 238 is provided with a threaded twill 240 having a lower end disposed in a corresponding one of the mounting blocks 218,220. The lower end of each rod 240 is connected to a corresponding block by a pin 242 to allow rotational movement of the rod 240 outward relative to the cover 232. The cover is provided with an inwardly extending slot 244 for a rod 240, the upper end of which is externally threaded and receives an internally internally threaded clasp handle 246. Thus, as can be seen, by unscrewing the handle 246 relative to the rod 240, the rod is rotatably movable out of the cover 232. Similarly, cover 232 covers handle 246.
The cover is held securely in place relative to the lower mounting block by screwing downward into tight engagement with the lower mounting block. As detailed in FIGS. 7A and 9, the cover 232 is provided with a plurality of gates 248 along its vertical centerline.

Each of the openings 248 is connected to the support block 216.218.
They are arranged so as to overlap in a ring space between two adjacent ones 220 and 222. Each closure 248 has a spring retaining sleeve 260 suitably secured to the cover by bolts 252.
Accept it. Each sleeve has an intermediate peripheral flange 256
and a lower end 258 for receiving and supporting a plunger component 254 . The lower end 258 extends through the opening in the sleeve 250 into engagement with the rolling ring section below.
A compression spring 260 is disposed between the flange 256 and the retaining odor cap, and the retainer cap 262 is suitably secured to the sleeve 250 to retain the panel. Spring 260 exerts a downward biasing force on the lower ring member, which causes the ring member to act against the lower adjustment cam. The support adjustment cam of each rolling ring member is arranged in an adjacent support block space, and is attached to the block so as to be rotatable around an axis parallel to the ring axis.

The cams are spaced laterally on opposite ends of the longitudinal centerline of the chest plate 214 so as to be engaged by circumferentially spaced corresponding rolling rings. Furthermore, the cam is independently rotatable about its axis, thereby making it possible to adjust the rolling ring axis horizontally and/or vertically. 8th
As shown in the figure, the cams 264, 266 are connected to the rolling ring 22.
The cams 268, 270 are disposed in the space between the mounting blocks 216, 218 to support the rolling ring 22.
The cams 272, 274 are arranged in the space between the mounting blocks 218, 220 to support the rolling ring 23.
0 in the space between the mounting blocks 220, 222. Each of the six cam parts is independently rotatable about its axis by a gear mechanism connected thereto, as described below.

The six cam parts have similar cross-sectional shapes and axial lengths that correspond to the spaces between adjacent mounting blocks.

Furthermore, the manner in which each set of cam and gear mechanisms is connected to the mounting block is similar. Therefore, only one set of cam and gear mechanisms will be discussed in detail herein. As shown in FIGS. 8-10, the cam 272 is disposed in the space between the mounting blocks 220, 222, and the cam 272 is located in the space between the mounting blocks 220, 222, and
76, 278 extend from both ends into holes provided in the mounting block.

The shaft portions 276, 278 are integral to the cam 272, and suitable bearing sleeves 280, 282 are interposed between the shaft portions and the holes in the mounting block so that the cam rotates around a horizontal ball 284 parallel to the ring axis. It is supported so as to be rotatable. The cam surface 286 is circular in cross-section and its axis 288 is laterally offset parallel to the cam's axis of rotation 284. Mounting block 2201
This is provided with a coaxially extending groove 290 in which a worm gear 292 is disposed and rotatably fastened onto the shaft portion 276. The mounting block 220 is further provided with a laterally extending hole 294 in which a gear drive shaft 296 is rotatably supported relative to the mounting block by a suitable bearing sleeve 298. A worm wheel 300 is provided at the inner end of the shaft 296, and the end of the hole 294 is widened to accommodate the worm wheel.
The worm wheel is rotatably attached to the shaft 296. The worm gear 292 and the worm wheel 300 are disposed in mesh with each other, and the adjustment nut 302 is connected to the pin 30.
4 to the outer end of shaft 296.
Rotation of the adjustment nut thereby causes worm wheel 300 to rotate through shaft 296, which in turn causes worm gear 292 and cam 272 to rotate about axis 284. Adjustment nut 302 is provided with a plurality of radially extending holes 306 suitable for receiving a suitable tool for manually rotating shaft 296. Preferably, the spring plunger 308 is attached to the foot plate 214 of the rolled ring nut by a support bracket 310 and is attached to the shaft 29.
6 is engaged with an adjustment nut 302 so as to suppress the rotation. The cam 274' has the same basic structure as the cam 272, as detailed in FIGS. 8, 9, 11, and 12.

Cam 274 includes camshaft portions 312, 314 that extend through holes in mounting blocks 220, 222, and bearing sleeves 316, 318 connect shaft portions and cam 274.
It is configured so as to be rotatably supported around a shaft 320. The shaft 320 is parallel to the rotation axis 284 of the cam 272 and the rolling ring axis, and the outer surface 322 of the cam 274 has a circular cross-section, and the mouse 324 on the surface is parallel and offset with respect to the shaft 320. Mounting block 2

As mentioned above, each of the three sets of cams has a gear mechanism for rotating it, preferably the gear mechanism being actuatable from a common side of the mounting block and mounted on the press frame as shown. It can be operated from the side of the block adjacent to the side. 7, 7A, 8, and 9, the leg plate 214 has a vertical center line 348 with a key register 350 vertically symmetrical about the center line 348.
is provided. Rolling ring support block 216,2
18, 220, 222 have key grooves 3 corresponding to their bottoms.
52.354, 356.358 are provided. Each of these key books is arranged in the center of the side of the support block and is attached to the leg plate 2.
14 key bases 350, and opposing key books receive a single key plate 360. The engagement relationship between the leg plate and the rolling ring support block allows the support block to be positioned on the leg ramp in the desired laterally aligned relationship, and the mounting plate is bolted in place on the leg ramp. This makes it possible to maintain this mutual relationship when As mentioned above, the leg plate 214 is mounted on a bolster plate 215 that is mounted on the horizontal frame plate 30.

A pin register 362 with a vertical axis 364 is provided at the end of the plate 214 which serves as an outlet for plunger engagement through the ring device. A vertical axis 364 intersects the longitudinal centerline 348 of the leg plate, and the bolster plate 215 has a pin riser 368 having a vertical axis 368 intersecting the longitudinal axis of the punch member 88.
66 are provided. Leg board 214 and polster board 215
is a pin 370 having a peripheral flange 372 between its ends.
The peripheral flange is received in the recess 374 of the bolster plate 215. The pin 37 is fastened to the bolster plate by a plurality of bolts 376 passing through the flange 372, and the pin is inserted into the pin groove 362.
It has coaxial upper and lower portions 378, 380 disposed at 366, respectively. The leg plate 214 and its rolling device are therefore horizontally rotatable about the axis 364, thereby providing a laterally angular arrangement of the rolling ring axis along with the punch axis. The movement of the rolling ring apparatus, preferably rotating about axis 364, is caused by the rolling ring support plate 215.
This is done by an adjustment screw mechanism that engages the and leg plates 214.

Although any suitable adjustment screw means may be used, the illustrated arrangement includes an adjustment screw 384 having a circular cross-section and a T-shaped head 386 received in a vertical T-slot 388 in the leg plate 214. A tool head 390 is provided on the outer part of the adjustment screw, and a part of the screw between the heads 386 and 390 has a male thread, and is suitable for insertion into a screw opening 392 of a support block 394 attached to the bolster plate 215 by a bolt 396. ing. Rotation of screw 384 relative to block 394 thereby causes the screw coaxial with sekiguchi 392 to move such that the rolling ring apparatus rotates about axis 364. When the rolling ring plate is thus rotated to align the ring axis with the ram axis, the leg plate 21
4 is fixed at the desired position. In the illustrated embodiment, such fixing is accomplished by a pair of fasteners 398 and bolts 40 located along the leading edge of the plate. In addition to providing key horizontal rotational adjustment of the rolling ring device as previously described, pin 370 takes on the entire thrust force created by the interlocking of the punch and can hollows through the rolling ring device. Preferably, the axis of the rolling ring associated with the pin moth 364 and the axis of the corresponding punch are coplanar in a vertical plane passing through the longitudinal centerline 348 of the rolling ring apparatus. Bottom Forming Bag Counterfeit E As shown in Figures 3, 13, and 14, the bottom forming device E consists of a pair of hemispherical surface forming devices 402 mounted on a horizontal support 404, and each hemispherical surface forming device has a corresponding one. The punches 88 are arranged in the direction of the ball.

Following the movement of the punch and the can hollow body through a rolling ring device in order to stretch and thin the sides of the can, as is well known,
The plunger is moved axially inwardly of the can side wall into engagement with the base forming device to create a hemispherical closure of the can hollow body. As shown in FIG. 15, the cross bar 404 is provided with a cutout 406 coaxially connected to the corresponding punch shaft.

The bottom forming device is fastened on the cross birch 404 so that the moving member of the device is coaxial with the punch axis. The bottom surface forming device includes a hemispherical surface forming head section 410 and a joint ring member 412.
It includes a hemispherical head 408 which is reciprocatable in the axial direction and includes a hemispherical head 408 consisting of an airline bar 414 and an airline bar 414. All of these components are loosely connected by a plurality of bolts 416. Piston 418 surrounds air shaft 414 and bolt 42
2, a cup-shaped cylinder member 42 is secured to the cross bar 404. The piston 4.18 is reciprocatable with respect to the cylinder member 420, and a passage 424 is provided at the end of the cylinder. Through that distance, pressurized air is sent to the cylinder behind the piston 418, thereby urging the piston in the punching direction.
Movement of the piston 418 and the hemispherical rhombus 400 in the alignment direction of the cylinder member 420 is restricted by a collar 426 . The collar 426 is internally threaded to engage with an externally male-threaded support ring 428 which is flush-mounted to the cylinder by bolts 430.
The collar 426 is thereby adjustable in the vertical direction relative to the cylinder member 420 to adjust the stopping point of the piston 418 and the hemispherical head assembly 406. A cylindrical bush 432 is installed at the entrance 406 of the cross bar 404.
is provided, and the pusher 432 is held in position with respect to the crossbar by a retaining ring 434 secured to the crossbar by bolts 436.

A lifting ring 438 that can freely reciprocate in the mouse direction is connected to the bush 4.
Air passages 440 and 442 are arranged in the air shaft 414 and the hemispherical head member 410, which are interposed between the hemispherical head member 410 and the hemispherical head member 410, respectively. Compressed air is sent to the rear of the lifting ring 038 through the passage, and urges the ring 438 in all directions of the corresponding punch member. Air wire core 4
14 and the air passage 424 of the cylinder member 420 are connected to a source of compressed air. During operation, the rolling can hollow body W on the punch 88 advances into engagement with the hemispherical head member 410 and the lifting ring 438, which rests on the peripheral edge between the can sides and the trim.

This engagement of the ring fairings causes the end wall to assume a hemispherical shape due to the continued action of the ram. During such action, the hemispherical head member 41 and the piston 418
The lifting ring 438 is moved in the direction of the ram's motion against the inertia of the rear compressed air, and the lifting ring 438 is moved in the direction of the ram's motion against the applied effort of the compressed air. During the bottom forming operation, the hemispherical forming head/lift ring member moves directly to the dashed line in FIG. Following the base-forming operation, the punch 88 retracts relative to the base-former and the hemisphere-forming head/lift ring member is brought to the solid line position in FIG. 15 by the piston 418 and the compressed air behind the lift ring. The lifting ring securely separates the can hollow body from the rhombus member in order to prevent the can hollow body from being moored by the bottom surface forming rhombus when the key is stored. Furthermore, this device is required to have excellent stability in moving operations.

It is therefore desirable for the fly to quickly adapt to the movement maneuver and to quickly move out of operative relationship with the punch member. In accordance with the present invention, this is accomplished by a cross section 404 rotatably mounted to the press frame to facilitate positioning the bottom forming pouch adjacent one or the other side of the frame. More specifically, as shown in FIGS. 3.13 and 14, the bottom forming block mounting plate 148 is provided with an annular support plate. Tsuku 444,4
46 are provided. Annular flanges 448 and 450 are attached to the block by welding or the like, respectively, and are connected to the mounting plate by bolts 452 or the like. Portion 104 of slide guide rod 100 extends axially beyond mounting plate 148 when the slide is in direct technician orientation, and mounting plate 148 is provided with a gateway for portion 104.
Furthermore, the inner diameter of the support blocks 444, 446 is
is sufficient to allow movement of the ends of the The outer end of the support block 414 is closed by a plate 45● which is fastened by welding or the like, and the plate 454 is provided with a threaded axially extending stud 456 at its outer end for receiving a nut 158. ing.

The outer shell of the support block 446 is likewise closed by a plate 4601 which is welded or otherwise fastened. The plate 460 is provided with an axially extending hinge arm 462 provided with a vertical pin entry 464 . The cross bar 404 runs horizontally across the press frame, and one end of the guide bar is laterally notched to connect each pair of arms 4 above and below the hinge arm 462.
66,468. Arms 466, 468 are provided with a stop that is aligned with stop 464, and a rotation pin 470 extends through the arm stop to rotatably connect crossbar 404 to hinge arm 462. Arm 46
6,468 is provided with a suitable sleeve bearing 472 for the end of the rotating pin. Washer 474
is hidden at the upper end of the pin 470, and the screw fastener 476
is fastened to it by. The diameter of washer 474 is larger than the diameter of the opening through arm 466 so that the washer engages the upper surface of the arm to retain pin 470 axially. Further, the pin 470 is attached to the hinge arm 46 by a set screw 478 that passes through the arm and engages a rotation pin.
2 and held against rotation. Support block 4
44 is provided with a laterally extending recess 480 through which the stud 456 passes.

The washer 482 is interposed between the nut 458 and the cross shank 404, the nut 458 is screwed into the screw register of the stud 456, and the end of the cross shank 404 is mated to the plate 454 and the mounting block 444. Similarly, when nut 458 is removed from stud 456, cross section 404 is relaxed to allow rotational movement in the horizontal direction about the vertical axis of rotation pin 470. The bottom forming bladder 402 supported by the cross bars is thereby movable into a position against one side of the machine.
Therefore, the bottom forming device, as well as the rolling ring and the product delivery material behind it, can be easily moved when the cross bars and the bottom forming device are in the non-crop position. Delivery Device G Following the base forming operation, the punch retracts towards its initial position.

During the start-up of the punch in the retraction direction, the can hollow body formed is then peeled off therefrom and removed from the machine. According to this invention, the first, 13th.
As shown in detail in Figure 16, there is a single star-shaped wheel located between the rolling ring diamond bottom and the bottom forming pupil.
484. A star wheel 484 is supported by the foot end plate 22 for rotation about a horizontal ball 486 parallel to the punch axis. In particular, the support bracket 488 is bolted or attached to the frame plate 22 and is further provided with a gearbox 490 having an output shaft 492 on which the star wheel 484 is rotatably mounted. The support bracket 488 further includes a take-out transmission 494 having an input shaft 496 and an output shaft 498.
This arrangement is capable of converting constant input rotation through shaft 496 into constant rotation of output shaft 498 in a known manner.

The input shaft 496 is suitably connected to the shaft 66, the seal 66 is rotated at a constant speed by means of the above-described driving means for the through-breath, and the output shaft 498 is connected to the input shaft to direct the input shaft 500. Ru. Gear pox 490 is operated to transmit the extraction rotation of input shaft 500 to the extraction rotation of shaft 492 and star wheel 484, the axis of the star wheel being perpendicular to the axis of input shaft 500. The drive mechanism for the delivery star wheel 484 is driven simultaneously with the reciprocating movement of the slide and punch to adjust delivery wheel ejection to the punch position.

To explain this point in detail, the lifting wheel 484
has 12 equally spaced pockets 5 around the wheel.
02 are provided, each pocket being accurately positioned to receive the forming can hollow body during the retraction movement of the punch. The diameter of the delivery wheel and the spacing of the pockets 502 around it are such that two pockets 502 are positioned to receive the forming can hollow upon retraction of the punch 88, and two additional pockets 502 are positioned between the can hollow receiving pockets. be done. After the rough ejection wheel drive mechanism receives the can hollow body from the punch, the ejection wheel advances in a 60° clockwise direction about axis 486 as seen in FIG. Since the forming can is delivered from the right hand side of the frame as seen in FIG. 16, the pocket of the star wheel approaching the left hand punch 88 during the removal movement of the star wheel 484 is always empty. The six-pin pick-up process moves the counterfeited can in the pocket of the star-shaped wheel to a position out of alignment with the punch, and at the same time moves the empty pocket into alignment with the punch so as to receive the formed can.

As the can is moved in a clockwise direction with the star wheel, the retaining wall 504 is moved until the pocket of the star wheel reaches the position of the delivery chute 506 where it is pulled from the machine.
held by. As mentioned above, the forming can hollow body is separated from the punch member during the start-up in the retraction direction with respect to the bottom forming device. The forming can hollow bodies are peeled from the punches in the desired manner, and a peeling device 508 is generally connected to each of the rolling ring devices in the delivery section shown in FIG. As is well known, the can stripping device operates to allow the can hollow body to pass together with the punch when the punch moves in the direction of the bottom forming bag. As the trailing edge of the can wall passes past the peel-off diamond, the peel-off diamond is actuated to engage the trailing edge of the can in response to movement of the punch away from the bottom-forming pouch. As a result, the punch retreats and causes the molded can hollow body to fall under gravity. The stripping mechanism does not form part of this invention, and other suitable mechanisms can be used to perform this stripping function. In the embodiment described above, the molding can hollow body fits into the pocket below the star wheel when the punch is released. The star wheel is removed following complete movement of the punch member from the forming can hollow body and prior to movement of the punch member and can hollow body beyond the delivery end of the rolling ring apparatus. Although considerable emphasis has been placed on the special grooves of the various components of the preferred embodiment of the horizontal rolling press of this invention, many changes and modifications may be made to the components without departing from the principles of the invention. Of course.

Such changes and modifications of the invention will be apparent from the foregoing description. Accordingly, the invention is capable of many embodiments and many modifications of the embodiments shown herein, and the foregoing description is merely illustrative of the invention and not limiting thereof.
