Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a wire drawing and wire twisting apparatus that performs wire drawing and wire twisting in tandem. Note that the term "twisted wire" or "twisting" herein includes not only gathering and twisting a plurality of wires but also winding a plurality of wires around a core wire in a layered manner.

[Prior art and its problems]

Conventionally, when producing stranded wire, the steps are taken to wind up a wire of a desired size produced by a wire drawing machine onto a bobbin, and then to attach the bobbin to a stranding machine and to perform the stranding. That is, conventionally, the wire drawing process and the wire twisting process could not be performed in tandem because the bobbin had to be attached and detached in the wire drawing machine and the wire twisting machine. For this reason, a bobbin stockyard or bobbin storage and transportation facility is required near the wire twisting machine, which not only increases equipment costs, but also requires intensive work to replace the bobbin of the wire twisting machine, which requires stopping the twisting machine, which reduces productivity. There was a limit to improvement.

A central rotating shaft in which a plurality of wire guide holes are provided in the axial direction in a part of the large diameter part that is larger in diameter than the small diameter part on the other end, and a large diameter part on one end of the central rotating shaft and a small diameter part on the other end of the central rotating shaft. a first hollow shaft and a second hollow shaft, each of which is coaxially and rotatably mounted to the central rotating shaft; a plurality of bobbins rotatably supported to the first hollow shaft; a plurality of bobbins rotatably supported on a second hollow shaft; a first flyer having both ends fixed to the first hollow shaft; and a second flyer having both ends fixed to the second hollow shaft; Each of the first hollow shaft and the second hollow shaft has a clutch mechanism for stopping the other when rotating the other and stopping one when rotating the other, and a plurality of strands to be twisted. It is equipped with two wire supply units that supply wires, and these two wire supply units alternately supply wires for twisting and wind up wires in preparation for twisting. A wire twisting machine that draws wire rods and produces wires to be twisted together, and a wire drawing machine that draws wire rods to produce wires to be twisted together, and a wire drawing machine that draws wire rods and produces wires to be twisted together. It is characterized by being combined with a wire winding mechanism that winds the wire directly into the wire supply unit.

That is, in the present invention, a wire twisting machine equipped with two wire supply units is used, and while one wire supply unit is twisting the wire, the other wire is kept on standby.
By winding the strands into the waiting unit while manufacturing the strands using a wire drawing machine, it is possible to draw and strand the wires in tandem.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows an embodiment of the present invention.
1 is a wire twisting machine, and 13 is a wire drawing machine.

The wire twisting machine 11 has the following configuration. That is, 15 is the central rotation axis, and this central rotation axis 1
5, one end side (right side in the drawing) half has a larger diameter than the other end side half, and a plurality of wire guides are provided in the axial direction in the part where the diameter is larger than the large diameter part 15a on the one end side and the small diameter part 15b on the other end side. A hole 17 is provided (see Figure 2). This central rotating shaft 15 is hollow, and a core wire 21 can be passed through the hollow portion 19 thereof.
Further, the central rotating shaft 15 is rotatably supported at both ends by a fixed frame 23 via bearings.
It is adapted to be rotationally driven from the outside via a wheel 25 attached to the other end.

A first hollow shaft 27a is coaxially arranged on the outer periphery of the large diameter portion 15a on one end side of the central rotation shaft 15, and is rotatably supported via a bearing. Similarly, a second hollow shaft 27b is coaxially disposed on the outer periphery of the small diameter portion 15b on the other end side of the central rotating shaft 15, and is rotatably supported via a bearing.

Further, a plurality of bobbins 29a are arranged coaxially around the outer periphery of the first hollow shaft 27a, and each bobbin 29a is rotatably supported with respect to the first hollow shaft 27a via a bearing. These bobbins 29a constitute a first bobbin group 31a. Similarly, a plurality of bobbins 29b are arranged coaxially around the outer periphery of the second hollow shaft 27b, and each bobbin 29b is rotatably supported with respect to the second hollow shaft 27b via a bearing. These bobbins 29b are the second bobbin group 3
1b.

A gear 33 is integrally provided on one side of each bobbin 29a, 29b, and an electromagnetic clutch 35 for braking is provided on the opposite side. The electromagnetic clutch 35 of the first bobbin group 31a is supplied with power from one end of the fixed frame 23 via a brush 37a and a slip ring 39a, and the electromagnetic clutch 35 of the second bobbin group 31b is supplied with electricity from one end of the fixed frame 23. Power is supplied from the end side via the brush 37a and the slip ring 39b.

Further, a first flyer 41a that straddles the first bobbin group 31a is fixed to both ends of the first hollow shaft 27a, and rotates together with the first hollow shaft 27a. Similarly, the second hollow shaft 27b
A second flyer 41b that straddles the second bobbin group 31b is fixed to both ends of the second hollow shaft 27b.
It is designed to rotate as one. A guide roll 45a is attached to the first flyer 41a to guide the wire 43 drawn out from the bobbin 29a. A similar guide roll 45b is also attached to the second flyer 41b.

Further, a clutch mechanism 47a is provided between one end of the first hollow shaft 27a and the fixed frame 23. This clutch mechanism 47a is connected to the central rotating shaft 15.
a clutch plate 49a that is rotatable relative to the clutch plate 49a and slidable in the axial direction;
It consists of a flange 51a fixed to 5, etc. The clutch plate 49a is always spline connected to the first hollow shaft 27a, and is integral with the first hollow shaft 27a regarding rotation and stopping. When the clutch plate 49a is moved to the left as shown in the figure, it is no longer engaged with the fixed frame 23 and is engaged with the flange 51a, so that the center rotation shaft 15
rotation is transmitted to the first hollow shaft 27a. Conversely, when the clutch plate 49a is moved to the right, the engagement with the flange 51a is broken and the fixed frame 2
3, so the first hollow shaft 27a
becomes stationary.

A similar clutch mechanism 47b is also provided between the other end of the second hollow shaft 27b and the fixed frame 23. In the illustrated state, the clutch plate 49b is moved to the left, disengaged from the flange 51b, and engaged with the fixed frame 23. In other words, the second hollow shaft 27b is in a stationary state.

Next, 53 is a bobbin drive mechanism, which includes a rotating arm 54 that is rotatably attached to a drive shaft 55 that is a spline shaft arranged parallel to the central rotating shaft 15, and A gear 57 is provided and splined to the drive shaft 55.
a and a gear train 57 that meshes with the gear 33 attached to the bobbin 29b via an intermediate gear 57b, and transmits the rotation of the drive shaft 55 to the bobbin 29b from the outside to drive the bobbin to rotate. There is. The drive shaft 55 is rotationally driven by a motor (in this embodiment, a wire drawing machine drive motor), which is not shown.

As shown in FIG. 3, the bobbin drive mechanism 53 is in a drive position (solid line) where it meshes with the gear 33 of the bobbin 29b and a retracted position (dotted line) where it does not mesh with the gear 33 and does not interfere with the rotation of the flyer 41b. As shown in FIG.
It is possible to move in the bobbin arrangement direction toward b.

That is, as shown in FIG. 1, a gear part 54a is formed at the end of the rotating arm 54 on the drive shaft 55 side, a small gear 56 is meshed with this, and this gear is rotationally driven by a motor 58. As a result, the rotating arm 54 is rotated around the drive shaft 55 within a predetermined angle range that hits a stopper (not shown), the bobbin drive mechanism 53 is set to the drive position when the rotation of the flyer 41b is stopped, and the gear is rotated. 33 to rotate the bobbin 29b, and wind the wire 43 supplied from the outside into the empty bobbin 29b, and when the winding of the wire into the bobbin is finished, the bobbin drive mechanism 53 to the retracted position to prepare for winding the wire 43 into the next empty bobbin 29b.

When rotating the bobbin 29b, the flyer 41 is of course kept stationary at a position that does not interfere with the movement of the bobbin drive mechanism 53. In addition, the small gear 56
The motor 58 is installed in a moving block 60, which will be described later.

Next, in the example shown in FIG.
Since only one set is provided, it is necessary to set it in the retracted position and move it in the direction in which the bobbins are arranged to wind up the strands for each bobbin. For this purpose, a moving block 60 is hinged to the drive shaft 55 so that it does not rotate together with the drive shaft but is movable in the longitudinal direction, and both sides of the moving block 60 are protruded to connect the bobbin drive mechanism 53. A screw shaft 62 is screwed onto the moving block 60 in parallel with the drive shaft 55, and the screw shaft 62 is driven in forward and reverse rotation by a drive source (not shown) to rotate the moving block 60. When the bobbins are moved left and right in the direction of arrangement of the bobbins and come into contact with a limit switch (not shown), the rotation of the screw shaft 62 is stopped by that signal, and the bobbin drive mechanism 53 is
It is designed so that it can be set in a position that matches the bobbin that is used for winding. At this time, since the drive shaft 55 is a spline shaft as described above,
The bobbin drive mechanism 53 has a gear train 57 on the drive shaft 5.
Even if it is engaged with 5, it can move smoothly.

Furthermore, in the present invention, the wire 4 manufactured by the wire drawing machine 13
3 on the wire winding side bobbin (first
In the illustrated state, the bobbin 29b) is provided with a traverser 91 that reciprocates in the width direction of the bobbin 29b to directly wind the bobbin while aligning the bobbin 29b.

This traverser 91 has guide shafts 94, 94 in the width direction of the bobbin by normal rotation and reverse rotation of the screw shaft 93.
a moving frame 92 that can be moved in the left-right direction along In order to reciprocate by W and wind the strands 43 evenly over the entire width of the bobbin 29b, a traverse mechanism 96 that alternately rotates forward and reverse, and a movable frame 92 are mounted to move the strands 43 toward the bobbin. A track-type feeder 97 that sends out the feeder, guide rollers 98 and 99 that are provided before and after the feeder and are each composed of a pair of rollers and guide the strand 43 between them, and the feeder 9.
7 and a cutter 100 that is provided between the guide roller 99 and cuts the wire 43 that has been wound into the bobbin.

The fast forwarding mechanism 95 consists of a motor 95a and a gear transmission section 95b, and the traverse mechanism 96 consists of a motor 96a and a gear transmission section 96b.The interlocking system for each screw shaft 93 includes an electromagnetic clutch or other disengagement mechanism (not shown). is being intervened.
101 is a fixed member that supports the screw shaft 93 and the guide shafts 94, 94 at both ends. Rapid forwarding mechanism 95
The mechanism for forwarding and reversing the traverse mechanism 96 is a well-known technique, so a description thereof will be omitted.

In order to quickly move the movable frame 92 from one bobbin side to the other bobbin side using the fast feed mechanism 95 and stop it at a predetermined position of each bobbin, one of the two limit switches 102 provided near the collar of the bobbin for each bobbin must be turned on. This is done by detecting the position of the movable frame 92. This limit switch is also used by the traverse mechanism 96 to reciprocate the movable frame 92 by the width W of each bobbin.

Also, as a matter of course, the ratio of the reciprocating speed of the traverser 91 in the bobbin width direction and the rotational speed of the bobbin 29b is constant because it is necessary to wind the strands 43 around the bobbin in alignment at a constant winding pitch. This detects the rotational speed of the drive shaft 55 or bobbin 29b as a pulse signal or other electrical signal, and controls the rotational speed of the motor 96a of the traverse mechanism 96 and the gear ratio of the gear transmission section 96b in accordance with the increase or decrease in the rotational speed of the drive shaft 55 or bobbin 29b. This is performed by a well-known traverse control means. The bobbin drive mechanism 53 and the traverser 91 are also movable toward the first bobbin group 31a, and when the first flyer 41a is stationary, they rotationally drive that bobbin 29a and apply an external source thereto. Roll up the supplied wire. Note that if the bobbin drive mechanism 53 is provided for each bobbin, it is possible to drive a large number of bobbins at once and wind up the strands at the same time.

Next, the operation of this wire twisting machine 11 will be explained. In the illustrated state, the center rotating shaft 15 and the first hollow shaft 27a are directly connected by the first clutch mechanism 47a, and the first flyer 41a is rotating around the first bobbin group 31a. For this reason, flyer 4
The strands 43 are pulled out from each bobbin 29a by the rotation of 1a (the pulling tension is adjusted by the electromagnetic clutch 35), and the drawn strands 43 are moved between the first hollow shaft 27a and the second hollow shaft by the guide roll 45a. 27b, and is further formed in the large diameter portion 15a of the central rotating shaft 15.
7 to one end of the central rotating shaft 15,
After being divided at equal intervals by the guide roll 59,
It is twisted onto the core wire 21 using the twisting cap 61.

On the other hand, on the other end side, the fixed frame 23 and the second hollow shaft 27b are directly connected by the clutch mechanism 47b, and the second flyer 41b is in a stationary state. The wire 43 is wound onto the bobbin 29b.

That is, by rotating the screw shaft 62, the bobbin drive mechanism 53 is moved to the moving block 60.
, and stops the movement at a predetermined position corresponding to the second empty bobbin 29b from the right side in FIG. 1, for example.

Next, the motor 58 is rotationally driven to rotate the rotating arm 5.
4 to the bobbin side, and the bobbin drive mechanism 5
3 to the drive position (solid line position in Figure 3),
The gear 57c of the bobbin drive mechanism 53 is connected to the bobbin 29b.
The wire drawing machine 1 meshes with the gear 33 attached to the wire drawing machine 1.
The bobbin 29b can be rotated by the rotational driving force of the drive shaft 55 which rotates in conjunction with the bobbin 29b.

On the other hand, the traverser 91 is rapidly moved toward the bobbin 29b by the fast-forwarding mechanism 95, and stopped at a predetermined position near one collar of the bobbin 29b by a signal from the limit switch 102.

Next, the wire 43 produced by drawing with the wire drawing machine 13
is guided to and captured by a sending device 97 mounted on the traverser 91, and the starting end of the wire 43 is sent out by the operation of the sending device 97, and fixed to the winding drum or collar of the bobbin 29b by appropriate means.

Next, the rapid forwarding mechanism 95 of the traverser 91 is switched to the traverse mechanism 96 by operating the dissociation mechanism to enable operation, and the sending machine 97 of the traverser 91 is opened to be inactive, and the wire drawing machine 13 is started. In synchronization with this, the traverse mechanism 9
6 operates the traverser 91, the drive shaft 55 is rotationally driven by receiving power from the wire drawing machine 13, the bobbin drive mechanism 53 starts rotating the bobbin 29b, and the bobbin 29b is manufactured by the wire drawing machine 13. The strands 43 are aligned and rolled up.

When the wire is fully wound in this way, the wire drawing machine 13 is stopped, the traverse mechanism 96 of the traverser 91 is made inactive, and the bobbin 29b is
stop rotating.

Next, the feeder 97 is closed to clamp the wire 43, and the cutter 100 is operated to cut the winding end of the wire.

Next, the bobbin drive mechanism 53 is set from the drive position to the retracted position, moved to, for example, another empty bobbin 29b located next to the bobbin, stopped at a predetermined position, and the bobbin drive mechanism 53 is moved to the drive position. Set to .

On the other hand, the traverser 91 is also rapidly moved by the rapid feed mechanism 95 and stopped at a predetermined position on the other bobbin.

Next, by operating the sending device 97 of the traverser 91, the winding start end of the wire is fixed to the other bobbin 29b.

In this way, the wire drawing machine 13 is operated again to wind into another bobbin 29b, and when winding of the wire 43 into that bobbin is completed, winding into another bobbin is performed one after another, and each bobbin 29b
When the bobbin is fully wound, the bobbin drive mechanism 53 is set to the retracted position in preparation for the next twisting. Then, just before the bobbin 29a on one end side becomes empty, the rotation of the first flyer 41a is stopped, and the strands 43 drawn out from the bobbin 29b on the other end side are attached to the rear end of each strand 43.
After that, the second flyer 41b is rotated to restart twisting. Twisting is continued by repeating the above operations.

In the above embodiment, the case where one strand of wire is wound onto each bobbin has been described, but two or more strands of wire may be wound onto each bobbin in parallel. In this way, it is possible to twist twice or three times as many wires as the number of bobbins.

As is clear from the above explanation, this stranding machine 1
1 includes a first wire supply unit 63a and a second wire supply unit 63b,
The strands 4 are alternately supplied from those strand supply units.
3 and continuously twists the wire.

The present invention provides a wire drawing machine 1 that draws the wire rod 65 to a required size in tandem with such a wire twisting machine 11.
3, and a traverser 91 for directly winding the wire 43 produced by the wire drawing machine 13 into the bobbin on the wire winding side of the wire twisting machine 11 (bobbin 29b in the state shown in FIG. 1). be. The wire drawing machine 13 is linked with a bobbin drive mechanism 53,
When the drive mechanism 53 rotationally drives the bobbin 29, the wire drawing machine 13 also becomes operational, and the drawn wire 43 passes through the traverser 91 and is transferred to the bobbin 2.
I'm starting to get caught up in 9b. The traverser 91 reciprocates by the bobbin width W by repeating forward and reverse rotation of the screw shaft 93, and the traverser 91 reciprocates by the bobbin width W.
The strands 43 are wound evenly over the entire width of b. When one bobbin is fully wound in this way, the bobbin drive mechanism 53, wire drawing machine 13, and traverser 91 stop, and the bobbin drive mechanism 53 moves along the drive shaft 55 to the next empty bobbin position. The traverser 91 is also moved to the empty bobbin position by the rotation of the screw shaft 93, and then the wire is wound into the empty bobbin. In other words, in this device, the bobbin drive mechanism 53 and the traverser 91 are used as a set to wind up the wire, and both constitute a wire winding mechanism.

Note that 67 is a supply device for the wire rod 65, and 69 is a dancer that adjusts the tension of the wire 43 wound around the bobbin 29b.

Furthermore, when winding two or more wires in parallel onto each bobbin, a multi-head type wire drawing machine is used.

Next, FIG. 4 shows another embodiment of the present invention. Fourth
In the figure, parts corresponding to those in FIG. 1 are given the same reference numerals as in FIG. 1.

This device is also composed of a wire twisting machine 11 and a wire drawing machine 13, but the configuration of the wire twisting machine 11 is different from that in FIG.

That is, in the wire twisting machine 11, the central rotating shaft 1
5, fixed frame 23, first hollow shaft 27a, second hollow shaft 27b, first clutch mechanism 47a,
The structure of the second clutch mechanism 47b and the like is the same as that in FIG. 1, but the other structure is different from that in FIG.

That is, the first bobbin support 71a is coaxially arranged on the outer periphery of the first hollow shaft 27a, and is rotatably supported via a bearing. Similarly, a second bobbin support 7 is provided on the outer periphery of the second hollow shaft 27b.
1b are coaxially arranged and rotatably supported via bearings.

Further, a plurality of (two in the illustrated example) bobbins 29a are attached to the first bobbin support 71a with their axes perpendicular to the first bobbin support 71a. Similarly, the same number of bobbins 29b are attached to the second bobbin support 71b.

Further, a first flyer 73a whose both ends are fixed to the first hollow shaft 27a and which rotates integrally with the hollow shaft 27a is provided with a pull-out guide 75a attached to each bobbin 29a for pulling out the wire 43 from the bobbin 29a. It is being Similarly, a similar pull-out guide is attached to a second flyer (not shown) which has both ends fixed to the second hollow shaft 27b and rotates integrally with the hollow shaft 27b.

Further, the first hollow shaft 27a and the first bobbin support 71a can be locked against relative rotation by a first locking mechanism 77a. This locking mechanism 77a changes the relative position of the first bobbin group 29a and the first flyer 73a between a position where the first rotating frame 73a straddles the first bobbin group (the illustrated position) and a position where the first rotating frame 73a does not straddle the first bobbin group. This is for locking the camera in a position perpendicular to the page. Similarly, the second hollow shaft 27b and the second bobbin support 71b can be locked against relative rotation by a second locking mechanism 77b. This lock mechanism 77b
is the relative position between the second bobbin group 29b and the second flyer (not shown, but perpendicular to the page), and the position where the second flyer straddles the second bobbin group (same as the page) This is for locking in a position (perpendicular to the plane of the paper) where there is no straddling.

Next, 79 is a wire winding mechanism, and the bobbin 2
The center of rotation is on the axis of bobbin 29b.
A substantially Z-shaped rotating arm 83 that rotates around the periphery of the rotating arm 83 and a motor 81 that rotationally drives the rotating arm 83.
and a rotary arm 83 and a motor 81 are mounted and reciprocated in the axial direction of the bobbin 29b,
The wire 43 produced by the wire drawing machine 13 is transferred to the rotating arm 8
3 and a traverser that winds the entire width of the bobbin 29b evenly. The traverser is substantially the same as that shown in FIG. 1, and is not shown because it is well known in the wire winding field. This strand winding mechanism 79 as a whole reciprocates in the axial direction of the bobbin 29b.
The strands 43 are wound evenly over the entire width of the wire. After winding the wire onto one bobbin, the bobbin support 71b is rotated to wind the wire onto another empty bobbin. Wire winding mechanism 7
9 is retracted to a position where it does not come into contact with the flyer when the wire is not being wound. The wire winding mechanism 79 is also movable toward the first bobbin group 29a, and when the first bobbin group 29a is stationary, it moves there and winds the wire. . Note that if a wire winding mechanism is provided for each bobbin, wires can be wound into a large number of bobbins at the same time.

Next, the operation of this wire twisting machine 11 will be explained. In the illustrated state, the center rotating shaft 15 and the first hollow shaft 27a are directly connected by the first clutch mechanism 47a, and the first flyer 73a is locked in a position where it straddles the bobbin 29a. The first bobbin group 29a is in a state of rotation together with the central rotating shaft 15. The strands 43 drawn out from each bobbin 29a by the rotation of the drawing guide 75a are
The wire is guided between the first hollow shaft 27a and the second hollow shaft 27b by the guide roll 45a on the flyer 73a, and further passes through the wire guide hole 17 formed in the large diameter portion 15a of the center rotating shaft 15 to the center. After being pulled out to one end of the rotating shaft 15 and separated at equal intervals by a guide roll 59, the core wire 2 is twisted by a twisting cap 61.
1 is twisted together.

On the other hand, on the other end side, the fixed form 23 and the second hollow shaft 27b are directly connected by the clutch mechanism 47b, and the second bobbin group 29b is in a stationary state. Further, the second flyer is locked in a position where it does not straddle the bobbin 29b (a position perpendicular to the plane of the paper). In this state, while the above-mentioned twisting is being performed, the wire winding mechanism 79 winds the wire 43 onto each bobbin 29b. When each bobbin 29b is fully wound, the second flyer is returned to the position straddling the bobbin 29b and locked, in preparation for the next twisting. Immediately before the bobbin 29a at one end becomes empty, the rotation of the first hollow shaft 27a is stopped, and the strands 43 pulled out from the bobbin 29b at the other end are attached to the rear end of each strand 43.
After that, the clutch mechanism 47b is switched, the second hollow shaft 27b is rotated, and the twisting is resumed. Twisting is continued by repeating the above operations.

Although the above-mentioned wire twisting machine describes the case where one strand of wire is wound onto each bobbin, two or more strands of wire may be wound onto each bobbin with one twist per turn of the bobbin. . In this way, it is possible to twist two or three times as many strands as the number of bobbins.

In addition, in the above-mentioned wire twisting machine, the strands wound around the bobbin are pulled out in the axial direction of the bobbin using a pull-out guide, but when two or more strands are wound in parallel, this drawing method In that case, each bobbin should be able to rotate around its own support shaft, and as shown by the dotted line on the side of the first bobbin group 29a in FIG. What is necessary is just to pull it out in the axial direction of 27b. Further, winding of the strands in this case may be carried out by rotationally driving the bobbin 29b by the motor 85 for winding the strands, as shown by the dotted line on the second bobbin group 29b side in FIG. Although not shown in the figure, a traverser is also used in this case.

As is clear from the above explanation, this stranding machine 1
1 also includes a first wire supply unit 63a and a second wire supply unit 63b,
The strands 4 are alternately supplied from those strand supply units.
3 and continuously twists the wire.

The present invention provides a wire drawing machine 1 that draws the wire rod 65 to a required size in tandem with such a wire twisting machine 11.
3 is installed, and the wire 43 produced by the wire drawing machine 13 is passed through the wire winding mechanism 79 to the bobbin (bobbin 29b in the state shown in FIG. 4) on the wire winding side of the twisting machine 11.
It was designed so that it could be directly involved. Wire drawing machine 1
3 is designed to perform wire drawing in conjunction with a wire winding mechanism 79.

〔Effect of the invention〕

As explained above, according to the present invention, the wire drawing process and the wire stranding process can be performed in tandem, so there is no need to attach or detach the bobbin or to transport it, and the manufacturing process of the stranded wire can be greatly simplified and labor can be saved. In addition, since the strands can be obtained in the state of wire rods before being drawn, the number of different sizes can be reduced, and the wire rod sizes can be easily managed.
