Description

The present invention relates to an apparatus for applying a molding oil to a surface of a metal plate to be pressed before pressing.
The present invention is very useful for improving the environment and efficiency of press working that requires molding oil.

Molding oil refers to oil that adheres to the surface of the metal plate to be processed before pressing, for example, when using the prior art (conventional molding apparatus) in Patent Document 1 below. As described above, the formation of the oil film may ensure good quality and yield of the press work.
In addition, as a means for automatically depositing the oil film on the surface of the metal plate on the press production line, fine oil droplets of molding oil are sprayed on the surface of the metal plate by spraying based on pressure. Spraying devices have been used exclusively in the past.
JP-A-10-134709 (FIG. 5)

However, when the conventional spray device described above is used, there is a risk that minute oil droplets of the molding oil or gas in which it has volatilized will fill the spray processing environment and damage the operator's throat and eyes. It was. For this reason, these workers have inconveniences such as having to wear a mask, glasses, and the like.
Further, as long as such a molding oil film formation method is followed, it is difficult to avoid the problem that the usage efficiency of the molding oil does not increase. Furthermore, in such an environment, the problem of contamination of peripheral devices and the like due to molding oil diffused in the air tends to become prominent.

  In addition, before the metal plates are stacked in the stacking device for transporting the metal plates, the molding oil is applied to each metal plate, and then the metal plates are stacked in the multilayer shape. A method is also conceivable in which each metal plate is taken out from the sheet and entered into a conveyance line for press working. However, in this method, when a large number of metal plates are loaded, the metal plates may be firmly adhered to each other by the action of the weight of the metal plates and the forming oil. For this reason, there arises a problem that it becomes difficult to reliably remove the metal plates one by one from the metal plate group. And this problem cannot always be solved easily.

  In addition, a method of dropping molding oil directly onto the metal plate being transported and then extending the molding oil with a spatula or the like is also conceivable, but in this method, when the transport speed of the metal plate is high, It becomes very difficult to control the amount of oil evenly applied to each metal plate or to accurately control the position of the oil. Therefore, in such a method, it is difficult to form a uniform oil film on each metal plate and each part on any one metal plate without any unevenness. Further, in this method, a desired oil film cannot be formed on the back surface (that is, the lower surface) of the metal plate.

  The present invention has been made to solve the above-mentioned problems, and its purpose is to improve the environment in the field using a molding oil for press working and to improve the efficiency of using the molding oil. It is.

In order to solve the above problems, the following means are effective.
That is, the first means of the present invention is a device for applying molding oil to a surface of a metal plate to be pressed before pressing, on a conveying line formed by a conveying device that conveys the metal plate to the pressing device. A molding oil application member that applies the molding oil to the surface and supports the molding oil application member from the side is provided by temporarily adsorbing and holding the molding oil and directly touching the surface of the metal plate. The supporting plate material, a brushed tube that rotatably supports the forming oil applying member and the supporting plate material so that the forming oil applying member contacts or separates from the metal plate, and the forming oil on the forming oil applying member or the supporting plate material. So that the forming oil is continuously applied to the molding oil application member, and the molding oil once applied to the surface of the metal plate by the molding oil application member is made more uniform or thinner. , Surface the molding oil while touching the surface An oil receiving means having a plurality of oil dripping holes disposed along the width direction at the lowest point. And an oil tank for storing the molding oil and a plurality of pipes for distributing the forming oil from the oil tank to the oil receiving pipe, each pipe on both sides of the conveying line passing through the center in the width direction of the molding oil application member. A plurality of bifurcated pipes connected to the oil receiving pipe at a plurality of pairs of positions at different distances from the transfer line, and disposed between the oil tank and each pipe. In addition, the molding oil coating apparatus includes a control valve that controls opening and closing of the oil supply path and a supply amount of the formation oil per unit time.
However, the molding oil application member may be any material as long as it can temporarily adsorb and hold the molding oil. For example, the molding oil application member is made of a fibrous material such as a brush or cloth, or a sponge material. be able to.

  Further, the second means of the present invention is the molding means for applying the molding oil to the surface on the front side of the metal plate and the molding oil to the surface on the back side of the metal plate in the first means. An oil application member.

Also, directly on the support plate which supports the molded oil applying member for applying the molding oil on the upper surface of the metallic plate, it may be added dropwise and molding oil from the dropping means.

The material constituting the Abura引-out extending means, good contact portion between at least the metal plate is anything if soft material so as not to scratch the metal plate. Therefore, for example, a material such as a wiper blade is suitable and is easily available.

In addition, a third means of the present invention is that the first or second means includes a surplus oil collecting means for collecting surplus molding oil that is excessively discharged when the molding oil is applied.

According to a fourth means of the present invention, in any one of the first to third means, the molding oil application member and the oil supply means are provided for different types of molding oil. .
By the above means of the present invention, the above-mentioned problem can be effectively or rationally solved.

The effects obtained by the above-described means of the present invention are as follows.
That is, according to the first means of the present invention, the molding oil application member is arranged on the conveying line formed by the conveying device that conveys the metal plate to the press working apparatus. During the transfer process, a desired oil film can be formed on the surface of the metal plate in parallel. In addition, since this treatment is performed by applying molding oil from a molding oil application member that directly touches the surface of the metal plate, the processing environment must be filled with minute oil droplets of the molding oil or gas from which it volatilizes. There is no.

Therefore, according to the first means of the present invention, the oil film can be efficiently formed in parallel with the conveyance process during the conveyance of the metal plate, and the on-site environment using the molding oil is improved. And improving the use efficiency of the molding oil at the same time.
In addition, since an appropriate amount of molding oil can be constantly held in the above-described molding oil application member, an oil film can always be formed without unevenness at least in the conveying direction on the surface of the metal plate. .

  Moreover, according to the 2nd means of this invention, a desired oil-fat film | membrane can each be formed into film on both front and back surfaces of the metal plate used as the object of press processing on said conveyance line.

In addition, due to the direct contact with the metal plate and the necessity of temporarily adsorbing and holding the molding oil, the above-mentioned molding oil application member requires remarkable flexibility and accurate positioning accuracy. According to the first means of the invention, since the molding oil application member is supported from the side by the support plate material, it is possible to simultaneously increase the positioning accuracy of the molding oil application member while ensuring good flexibility. Become. For this reason, the contact of the forming oil application member against the metal plate becomes too strong, or the forming oil application member escapes excessively against the contact of the metal plate, and the contact pressure of the forming oil application member against the metal plate becomes weak. It will never be over. For this reason, the contact condition of the molding oil application member with respect to the metal plate can be optimally controlled. Therefore, according to the first means of the present invention, the forming oil can be applied reasonably well to the metal plate.

In addition, according to the first means of the present invention, the oil supply portion of the oil supply means can be realized even by using, for example, a simple part in which an appropriate number of holes (: oil droplet dropping ports) are formed in the pipe. obtain. That is, according to the first means of the present invention, it is possible to configure the oil supply means in such a relatively simple form.

Further, in the first means, the forming oil may be dropped directly from the dropping means to the support plate material that supports the forming oil applying member that applies the forming oil on the upper surface of the metal plate. This embodiment is particularly effective when a structure connected in a direction perpendicular to the transport direction of the metal plate is given to the support plate material, and according to this configuration, in the longitudinal direction (transport direction) of the metal plate. In addition, a desired oil film can be formed substantially uniformly in the horizontal direction. This is because the support plate material acts as a buffer for temporarily holding the molding oil to be dropped, and at the same time acts to appropriately disperse the molding oil in the lateral direction (direction perpendicular to the conveying direction). This is to play.
Further, by optimizing the material, thickness, length and the like of the molding oil application member, such a buffering action and a dispersing action can be favorably obtained.

Further, according to the first means of the present invention, the molding oil once applied to the surface of the metal plate by the molding oil application member can be made more uniform or thinner by the oil stretching means. When the molding oil is applied to the surface of the metal plate by the molding oil application member, it is not always necessary to apply the molding oil sufficiently uniformly or sufficiently thinly.
In addition, according to the first means of the present invention, the thickness and uniformity of the oil film formed by the molding oil can be easily and optimally controlled.

In addition, according to the third means of the present invention, the surplus molding oil that has been left out during the application of the molding oil is recovered, so that the molding oil can be reused. For this reason, the use efficiency of molding oil can further be improved.

Further, according to the fourth means of the present invention, the type of molding oil to be used can be easily replaced as needed depending on the type of metal plate to be processed, while preventing different types of molding oil from being mixed. .

  The molding oil application member can be made of a porous sponge-like material or cloth material. However, when the conveying speed of the metal plate is high, the molding oil application member is not provided between the molding oil application member and the metal plate. The problem of friction in the surface may be easily surfaced. For this reason, as the material for the molding oil application member, it is desirable to use a material made of a synthetic resin such as a silicon-based or nylon-based material having a small coefficient of friction with the metal plate to be processed. In addition, since these synthetic resin materials have appropriate flexibility, they are suitable for always optimizing the contact pressure against the metal plate so that it is not greatly affected by the thickness of the metal plate. It is.

Hereinafter, the present invention will be described based on specific examples.
However, the embodiments of the present invention are not limited to the following examples.

FIG. 1 is a cross-sectional view perpendicular to the y-axis direction of the molding oil coating apparatus 100 of the first embodiment. The brush 101 constituting the molding oil application member of the present invention has a fixing bracket 109 and a bolt 117 on the resin cover 113a of the brushed tube 113 so that the brush 101 can rotate around the cylindrical axis of the brushed tube 113. It is fixed using etc. The brush 101 is a bundle of innumerable nylon fibers, and a support plate 105 is fixed between the fixing bracket 109 and the brush 101. This support plate material 105 ensures good positioning accuracy of the brush 101 with respect to the metal plate W, in order to maintain the shape of the brush 101 well, to ensure good contact pressure of the brush 101 with the metal plate W. Therefore, it is attached for a long time in the y-axis direction.
As shown in FIG. 1, the brushes 102 to 104 have the same configuration as described above.

  The upper brushed tube 113 and the brushed tube 115 are supported by the plate P3 so as to be rotatable around their own axes, and the lower brushed tube 114 and the brushed tube 116 are themselves Is supported by a plate receiving member 209 so as to be rotatable around the axis. However, for example, the brushed tube 113 and the brushed tube 114 are supported by the plate P1 in FIGS. 3 and 5B described later, and the brushed tube 115 and the brushed tube 116 are provided. Is supported by a plate P2 in FIG. 3 and FIG.

  At the lowest points of the oil receiving pipes 121 and 122 constituting the dripping means of the present invention, substantially cylindrical oil dripping holes 121a and 122a are provided, respectively. The oil supply branch pipes 123 and 124 for supplying oil to the oil receiving pipes 121 and 122 are made of a deformable copper flexible pipe material. The oil supply branch pipes 123 and 124 and the oil supply ports 125 and 126 are fixed to the base plate 127, respectively.

  The oil supply pipe 121, the oil supply branch pipe 123, the oil supply port 125, the brush 101, the brush 102, and the like are used when the metal plate W is made of an aluminum material. The oil supply pipe 122, the oil supply branch pipe 124, the oil supply port 126, and the brush 103 are used. The brush 104 is used when the metal plate W is made of iron. As described above, the molding oil application member (brushes 101 to 104) and the oil supply system (oil supply pipe, oil supply branch pipe, oil supply port, etc.) are divided according to the material of the metal plate W depending on the material of the metal plate W. This is because the type of molding oil to be used is different.

  For example, the brush 101 is a molding oil application member for applying molding oil for aluminum on the upper surface of a metal plate W made of aluminum or the like, and the brush 102 is used for aluminum on the back surface (lower surface) of the metal plate W made of aluminum or the like. The brush 103 is a molding oil application member for applying iron molding oil to the upper surface of the metal plate W made of iron or the like, and the brush 104 is iron or the like. It is a molding oil application member for applying the molding oil for iron to the back surface (lower surface) of the metal plate W made of. Moreover, each position of the shaping | molding oil application | coating member (brushes 101-104) illustrated in FIG. 1 is a retracted position when none of each blemish 101-104 is used, and at the time of use, the corresponding installation pipe | tube 113 with a corresponding brush. ˜116 are rotated as described above, and the corresponding brush (molding oil application member) is used while being appropriately brought into contact with the target metal plate W.

  For example, when the brush 101 and 114 are appropriately rotated so that the brush 101 and the brush 102 come into contact with each other as shown in FIG. 2A, the metal plate W is placed between the two brushes. When transported in the x-axis direction, molding oil can be applied to both the front and back surfaces of the metal plate W. At this time, it is desirable that the brush 102 located on the lower side protrudes slightly forward (side on which the x coordinate becomes larger). The appropriate range of the length δ (FIG. 2-B) is about 0 mm to 30 mm. With such setting, the molding oil once dripped on the support plate 105 can be distributed to the brush 101 and the brush 102 at an appropriate amount as needed so that there is no waste or unevenness.

Moreover, the setting of the length δ may be adjusted by the arrangement position of the brushed pipes 113 and 114, may be adjusted by the lengths of the brush 101 and the brush 102, or the brushed pipes 113 and 114 may be adjusted. You may adjust by each rotation angle at the time of rotating 114. FIG.
The same applies to the brushes 103 and 104, the brushed pipes 115 and 116, and the like.

  Below the brushed pipes 114 and 116, an oil pan 128 (surplus oil recovery means: FIG. 1) for recovering the unapplied excess of the molding oil is disposed. These oils fall into the oil pan 128 through the support plate members 106 and 108 and the fixing brackets 110 and 112. The cock 129 and the hose 130 in FIG. 3 are for collecting the molding oil accumulated in the oil pan 128 (surplus oil collecting means), and these oils are supplied to a predetermined point provided at the end of the hose 130. It is collected in a collection container.

  In FIG. 3, the front view of the board | plate material conveying apparatus 200 which has the molding oil application | coating apparatus 100 of the present Example 1 is shown. The substantially cylindrical oil dripping hole 121a is provided at the lowest point of the oil receiving pipe 121 as described above. The pitch (arrangement density) in the y-axis direction is the same as that in the y-axis direction of the oil supply branch pipe 123. It is set to about 2 to 3 times the pitch. 1 is indicated by the symbol E ′ in FIG. These oil supply ports are divided into a total of five oil supply systems of AA ′, BB ′, CC ′, DD ′, and EE ′.

  FIG. 4 shows a logical configuration of these oil supply systems. Five pipelines PL1 to PL5 are connected to an oil tank T that holds molding oil for aluminum, and each of the bifurcated branching devices (a2, b2, c2, d2) that divide the oil into two equal parts. , E2) and the oil tank T, control valves (a1, b1, c1, d1, e1) are respectively provided on these pipelines (PL1 to PL5). These control valves are configured using electromagnetic valves, and can freely control the opening and closing and the thickness of the oil supply path (that is, the amount of oil supplied per unit time).

Therefore, for example, when the width of the metal plate W, that is, the length in the y-axis direction is short, the control valves b1, c1, d1, and e1 are closed to supply oil only from the oil supply ports A, A ′. Molding oil can be dripped only in a narrow range in the axial direction.
Moreover, when the conveyance speed of the metal plate W is high, etc., each corresponding oil supply path can be secured thick based on the opening / closing control of the control valve according to the necessary and sufficient oil supply efficiency.
Of course, these configurations are also provided in parallel for the oil supply system for the molding oil for iron.

  Hereinafter, the rotation control means for rotating the brushed tubes 113 and 114 of FIG. 1 will be described with reference to FIGS. 3 and 5-B. This rotation control means is operatively fixed on the plate P1, and a cylindrical pin 137 fixed at an eccentric position on the disk 132 with its axis directed in the y-axis direction is provided by the shaft 139. By pushing and pulling up and down, the disk 132 rotates around the brushed tube 114 having the same axis. Reference numeral 135 denotes an air cylinder that drives this push-pull operation. In addition, the disk 132 and the disk 131 constitute a gear mechanism. That is, teeth that form gears are provided on the outer circumferences of the disc 132 and the disc 131, respectively, and the disc 132 and the disc 131 are circumscribed via these teeth, so that the disc 132 is rotated based on the rotation of the disc 132. A rotation of the disk 131 is generated.

  Further, since the disc 131 and the disc 132 have the same radius, the brushed tubes 113 and 114 fixed thereto are always rotated by the same rotation angle. For example, when the brush 101 and the brush 102 are retracted to the position shown in FIG. 1, that is, the position where the brush 102 does not contact the metal plate W, the shaft 139 may be pushed upward using the driving force of the air cylinder 135. . By this operation, as shown in FIG. 1, the brush 101 and the brush 102 can be retracted to a position where they do not contact the metal plate W.

  The holes h1 and h2 provided on the plate P1 are for penetrating the brushed pipes 115 and 116 shown in FIGS. 1 and 5-A, and the brush 103 and the brush 104 attached thereto are also provided. In substantially the same manner as described above, the rotation is controlled using the driving force of the air cylinder 136. However, when the brush 103 and the brush 104 are retracted to the position shown in FIG. 1, that is, the position where the brush 104 does not contact the metal plate W, the shaft 140 is pulled downward using the driving force of the air cylinder 136.

  According to the above configuration, since the above-described forming oil application members (brushes 101 to 104) are arranged on the conveyance line formed by the plate material conveyance device 200 that conveys the metal plate W to the press working device, the metal plate A desired oil film can be simultaneously formed on both the front and back surfaces of the metal plate W in parallel with the conveying process of W to the press working apparatus. In addition, since this processing is performed by application of molding oil from a molding oil application member that directly touches the metal plate W, minute oil droplets of the molding oil or gas from which it volatilizes is filled in the processing environment. Absent.

Hereinafter, the above-described transport line that is configured by the plate material transport apparatus 200 will be described more specifically. 6A and 6B are cross-sectional views of an opening / closing clamping mechanism of the plate material transport apparatus 200 for clamping a workpiece (metal plate). In particular, FIG. 6-A (open state) corresponds to an enlarged part of the front view of FIG. 3, and the base pillars 201 and 202 are fixedly fixed.
The grip members 203 and 204 directly hold the metal plate W by surface contact. However, in more detail, the grip member 203 includes a spring CC and a contact member 203b for exerting an elastic action for optimizing the grip pressure when the metal plate W is clamped, and the spring member CC and the contact member 203b are elastically finely moved in the z-axis direction. It is comprised from the back base 203a supported so that it is possible.

Since the open / close clamping mechanism of the plate material conveying apparatus 200 is configured substantially symmetrically with respect to the upper, lower, left, and right sides of the parts other than the grip members 203 and 204, the configuration of the upper half will be described in detail below.
A conveyance rail 205 extending long in the x-axis direction is fixed to the base pillar 201, and the holder 207 is reciprocally guided in the x-axis direction by the conveyance rail 205 while being fitted to the conveyance rail 205. . The holder 207 is fixed on a substantially plate-shaped base 210 as shown in the side view of FIG. 7-A. A base body 211 is fixed to the lower surface of the base 210, and the entire base body 211 can reciprocate in the x-axis direction. A vertical rail 212 is fixed to the side surface of the base body 211, and a horizontal rail 218 extending long in the x-axis direction is fixed to the lower surface of the base body 211.

The side plate 214 connects the grip member 203 and the holder 213. The vertical rail 212 guides the holder 213 in a reciprocating manner in the z-axis direction, and the side plate 214 is translated up and down based on this guide, whereby the grip member 203 is held in the vertical direction with respect to the metal plate W. Operation is realized.
The holder 217 is guided by a horizontal rail 218 so as to be reciprocable in the x-axis direction. The drive plate 216 to which the holder 217 is fixed can reciprocate in the x-axis direction along the horizontal rail 218 as shown in FIG. 7-A. The air cylinder 220 in FIGS. 7A and 7B is for driving the translational movement, and the drive plate 216 is connected to the air cylinder 220 via the shaft 221.

  The translational movement of the drive plate 216 in the x-axis direction is for generating the vertical movement of the side plate 214 described above. That is, as shown in FIGS. 7A and 7B, the drive plate 216 is provided with a cam follower 216a. The cam follower 216a is inserted into the guide hole 215a provided obliquely on the guide plate 215. In order to move along the guide hole 215a, the vertical movement of the side plate 214 fixed to the guide plate 215 is generated. For example, if the shaft 221 is pushed to the right (in the positive x-axis direction) by the air cylinder 220 in FIGS. 7A and 7B, the cam follower 216a is pushed to the right and the grip member 203 is lifted ( Fig. 6-A, Fig. 7-A).

  6A and 6B are also configured in the same manner as described above, and operate in substantially the same manner as described above. However, if the drive plate 216 ′ is pushed to the right (in the positive x-axis direction) by the air cylinder 220 ′ of FIG. 7-A, the grip member 204 is lifted. Executed when obtaining the closed state (FIG. 6B).

  For example, the present invention is implemented by disposing the molding oil coating apparatus 100 according to the first embodiment as illustrated in FIGS. 1 and 3, for example, on an appropriate conveyance line configured as described above. can do.

  Note that, depending on the above-described molding oil application member (brush 101 to brush 104), the molding oil cannot be directly applied to the central portion of the metal plate W, but for such a region on the metal plate W, If necessary, the molding oil may be attached by spraying in the same manner as in the past. Since such a region on the metal plate W is much narrower and limited than before, these configurations based on the present invention (in combination with the prior art) can also eliminate or greatly alleviate the above-mentioned problems. be able to.

  8A and 8B are a plan view and a cross-sectional view of the oil stretching means (wiper blades WB1 to WB4) of the second embodiment. The oil stretching means (WB1 to WB4) are arranged at the final stage of the plate material conveying apparatus 200 of the first embodiment. A point PP on the right side of FIG. 8A indicates the center point (processing position) of the press working apparatus, and the side gripper SG that holds the edges of the metal plate W on both the front and back sides from both sides of the conveying line is The metal plate W is conveyed in the x-axis direction from the point x = x2 to the point x = x3 (: point PP).

  In addition, the grip members 203 and 204 of the plate material transporting apparatus 200 hold the metal plate W from both the front and back surfaces by the above-described holding operation, and hold the metal plate W in the x-axis direction from the point of x = x1 x = x2. Transport to the point. The wiper blades WB1 to WB4 are provided at the exit of the plate material conveying apparatus 200, that is, near the delivery point of the metal plate W with respect to the side gripper SG, and the cross section α is as shown in FIG. ing.

The cross-sectional view of FIG. 8B is a view of the cross section α of FIG. The plate material conveying apparatus 200 includes the molding oil application apparatus 100 of the first embodiment, and the oil film ρ1 of the molding oil in FIG. 8B is applied by the brush 101 described above. The oil film ρ1 is flattened by the wiper blade WB1 like the oil film ρ2 in the figure, and the wiper blade WB1 is further formed on the central portion of the metal plate W where the forming oil could not be applied by the brush 101. It also has the effect of carrying Then, the wiper blade WB2 at the next stage further flattens and thins the oil film ρ2 formed based on the action thereof, thereby forming a thinner oil film ρ3 as shown.
For example, when a wiper blade is used in this way, even if there is a portion where the molding oil cannot be applied by the molding oil application member, a desired oil film is formed on both the front and back surfaces of the metal plate W without any unevenness. Can be membrane.

  Further, a small amount of molding oil may be injected in the vicinity of the region Z in FIG. 8A by means similar to the conventional one (: nozzle for spraying molding oil with a fixed installation position). Thereby, since generation | occurrence | production of the friction which arises between the wiper blades WB1-4 and the metal plate W can always be suppressed, while the lifetime of the wiper blades WB1-4 can be lengthened, the above flattening and Thinning can be performed more reliably. About such spraying of molding oil, since the spraying range is remarkably narrower than before, the spraying amount can be suppressed to be sufficiently smaller than before. For this reason, even in such a case, the same operation and effect of the present invention as in the first embodiment can be obtained.

[Other variations]
The embodiment of the present invention is not limited to the above-described embodiment, and other modifications as exemplified below may be made. Even with such modifications and applications, the effects of the present invention can be obtained based on the functions of the present invention.
(Modification 1)
For example, in the first embodiment, the support plate material 105 and the support plate material 107 are made flat and flat, but unevenness is formed on the surface of the upper support plate material (105, 107) on which the molding oil is directly dropped. May be.

  FIG. 9 illustrates a modification of the support plate material 105. A large number of protrusions 105a are provided on the support plate member 105 'of FIG. By forming such irregularities, it is possible to form a desired oil film in a uniform and uniform manner both in the vertical direction (conveying direction) and in the horizontal direction of the metal plate. This is because the above-mentioned support plate material 105 ′ has a buffer function that once holds the dropped molding oil, and at the same time has an effect of appropriately dispersing the molding oil in the lateral direction (direction perpendicular to the conveying direction). Is to play at the same time.

(Modification 2)
Further, in the above-described embodiment 1, the form in which the excess of the molding oil recovered through the hose 130 (FIG. 3) is recovered in a predetermined recovery container, but in the molding oil application apparatus of the present invention, A circulation path that automatically reuses the excess molding oil once recovered may be configured by using a pump, a dust collection filter, or the like.

(Modification 3)
Further, the oil receiving pipes 121 and 122 (molding oil dropping means) of the first embodiment are separately provided for a molding oil application member (for example, for the brush 102) for applying molding oil to the back surface of the metal plate. it can. Further, in such a case, for example, the brush 101 and the brush 102 can be individually refueled by separate dropping paths. In such a case, as shown in FIGS. It is not always necessary to consider the positional relationship between the brush 101 and the brush 102.

(Modification 4)
Moreover, in Example 1, although the oil supply means of this invention was comprised using the oil receiving pipes 121 and 122 (dropping means of this invention) which have the oil dripping holes 121a and 122a, the oil supply means of this invention does not necessarily have It is not necessary to comprise the dropping means of the present invention.
For example, it is also possible to supply molding oil into a brushed tube such as the brushed tube 113 or the brushed tube 115 of the first embodiment and distribute the molded oil to each brush from there. In this case, holes having substantially the same shape as the oil dripping holes 121a, 122a and the like are provided in the brushed pipes, and a molding oil application member such as a brush is disposed immediately below the holes, thereby implementing the above-described embodiment. The oil supply method (FIG. 4) of No. 1 can be used to supply oil in substantially the same manner.

  The present invention relates to a means for forming an oil film of a molding oil on the metal plate before pressing the metal plate. The present invention is very effective when, for example, a vehicle body is molded using a press apparatus.
