Description

Sheet product pressing mechanism

Technical Field

The present invention relates to a sheet product pressing mechanism, and more particularly, to a sheet product pressing mechanism disposed in a press forming apparatus.

Background

In a heat-radiating fin that is a part of a heat exchanger used in a cooling apparatus or the like, a metal thin plate is formed into a predetermined shape by a press-forming apparatus, and the metal thin plate is conveyed to each portion in the order of a die punching portion, an inter-row slit forming portion, a cutting portion, and a product stacking portion. In such a press-forming apparatus, since a press-formed product (hereinafter, referred to as a thin product) that has passed through a die press section is punched out in a large number of portions, the thin product may buckle during conveyance in the press-forming apparatus. In recent years, patent document 1 (japanese patent No. 6723678) proposes a press forming apparatus in which a thin plate product pressing mechanism (upper guide plate) for pressing a thin plate product downward from above a conveying path (lower guide plate) is provided in order to protect the thin plate product from buckling during conveyance.

SUMMERY OF THE UTILITY MODEL

Problem to be solved by utility model

As shown in fig. 8, the thin-plate product pressing mechanism of patent document 1 is configured such that a bolt 101 is used to fix the thin-plate product pressing mechanism 100 to the right and left sides in the conveying direction at a position in the middle of a conveying path 201 of the thin-plate product in a press forming apparatus 200 (see fig. 1). By adopting such a fixing structure, the sheet product pressing mechanism 100 can be reliably fixed. However, when removing the thin-plate product pressing mechanism 100 during maintenance or the like, the operator needs to remove the bolt 101 on the right or left side of the press molding device 200 and then move the thin-plate product pressing mechanism 100 to the side opposite to the press molding device 200. Therefore, there is a problem that the operation of removing the thin-plate product pressing mechanism 100 is complicated.

Means for solving the problems

The present invention has been made to solve the above problems, and its object is as follows. That is, a thin-plate product pressing mechanism capable of easily performing an attaching/detaching operation to/from a press-forming device is provided.

The present inventors have made intensive studies to solve the above problems, and as a result, have conceived the following configurations. That is, the present invention is a thin plate product pressing mechanism which is disposed in a conveyance path of a press forming device and presses a thin plate product supplied to the press forming device from above the conveyance path toward the conveyance path, the thin plate product pressing mechanism including: a 1 st coupling section that is disposed at a right position or a left position in the conveying direction of the conveying path, and that is attached to be rotatable about a rotation shaft extending in the conveying direction of the conveying path; a 2 nd connecting part, disposed at a position opposite to the conveying path with respect to the mounting position of the 1 st connecting part, and erected in a direction rising from an upper surface of the conveying path; a pressing member formed to have a size covering an upper surface of the conveying path in a desired range, the pressing member pressing the sheet product conveyed along the conveying path toward the conveying path; a 3 rd coupling portion which is attached to a 1 st end portion side in the width direction of the conveying path of the pressing member, which is paired with the 1 st coupling portion, and which is coupled to the 1 st coupling portion so as to be insertable into and removable from the 1 st coupling portion; and a 4 th coupling part which is attached to a 2 nd end part side in the width direction of the pressing member, which is paired with the 2 nd coupling part, and which is coupled to the 2 nd coupling part so as to be able to be inserted into and pulled out from the 2 nd coupling part.

Therefore, when the operator removes the sheet pressing mechanism during maintenance or the like, the operator only needs to insert and remove the sheet pressing mechanism into and from the connecting portion from one side of the press-formed article manufacturing apparatus, and does not need to move the sheet pressing mechanism to the opposite side of the press-formed article manufacturing apparatus. Therefore, the attachment/detachment operation of the thin-plate product pressing mechanism can be very easily performed.

Preferably, at least one of the 1 st coupling part and the 3 rd coupling part is a convex part having a tip formed as an enlarged diameter part and the other is a concave part capable of holding the enlarged diameter part, or at least one of the 2 nd coupling part and the 4 th coupling part is a convex part having a tip formed as an enlarged diameter part and the other is a concave part capable of holding the enlarged diameter part.

This makes it easier to perform the operations of coupling and uncoupling the 1 st coupling part and the 3 rd coupling part, and the 2 nd coupling part and the 4 th coupling part.

Preferably, the upper surface of the conveying path has projections extending in the conveying direction of the conveying path at a plurality of positions with a desired interval therebetween in the width direction of the conveying path, the lower surface of the pressing member has a plurality of projections aligned with the positions of the projections, and the thin plate product conveyed along the conveying path is sandwiched between the projections and the projections in the plate thickness direction.

Thus, the sheet product can be conveyed without damaging the sheet product and without buckling.

Effect of the utility model

By adopting the attachment/detachment structure of the thin-plate product pressing mechanism in the press-forming apparatus of the present invention, when the operator removes the thin-plate product pressing mechanism during maintenance or the like, the thin-plate product pressing mechanism can be inserted into and removed from the connecting portion from the side of the press-forming product manufacturing apparatus. Therefore, it is not necessary to move the thin plate product pressing mechanism to the opposite side of the press forming product manufacturing apparatus, and the operation of attaching and detaching the thin plate product pressing mechanism can be very easily performed.

Detailed Description

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. In the present embodiment, a metal strip of a product width, which is a press-formed product divided into product widths by an inter-row slit apparatus after being formed into a predetermined shape by a die press section, will be described as a thin plate product.

As shown in fig. 1, the press molding apparatus 200 of the present embodiment is provided with an uncoiler 212 in which a thin plate 210 made of metal such as aluminum as a thin plate material is coiled. Thin metal plate 210 drawn out from uncoiler 212 via pinch roll 214 is inserted into oil applying device 216, and after processing oil is attached to the surface of thin metal plate 210, the oil is supplied to die device 220 provided in die press 218. The die apparatus 220 includes an upper die set 222 capable of moving up and down and a lower die set 224 in a stationary state in an inner space of the die apparatus 220. With such a mold device 220, a primary molded product 230 is formed in which a plurality of heat radiating fins 250 are arranged in the width direction, and the heat radiating fins 250 have a plurality of flanged through holes and notches in which flanges of a predetermined height are formed around the through holes.

The primary molded product 230 formed by the mold device 220 is formed into a metal strip 240 of a product width divided into product widths of the heat dissipating fins by the inter-row slit device 225. The inter-row slit apparatus 225 cuts the primary molded product 230, which is formed by the die press section 218 and then intermittently conveyed by the conveyor 226, into a predetermined product width by the upper cutter 225A and the lower cutter 225B which are engaged with each other, and forms a strip-shaped metal strip 240 which is long in the conveying direction.

The metal strip 240 formed by the inter-row slit apparatus 225 is cut into a predetermined product length size by the cutting apparatus 227, and is formed into the heat radiation fin 250 of the manufacturing target product. The heat dissipating fins 250 thus formed are conveyed to the temporary holding device HD that performs the contact and separation movement in the width direction of the heat dissipating fins 250, and then stored in the stacker 228. A plurality of pins 229 are vertically erected on the stacker 228, and the heat dissipating fins 250 are stacked and held on the stacker 228 by inserting the pins 229 into through holes and notches formed in the heat dissipating fins 250. Since the structure of the press-forming apparatus 200 is well known, detailed description of each structure of the press-forming apparatus 200 will be omitted here.

As shown in fig. 2, the thin-plate product pressing mechanism 100 of the present embodiment is configured to be separable and is disposed between the inter-row slit device 225 and the cutting device 227 of the press forming device 200. The thin-plate-product pressing mechanism 100 includes a 1 st connecting part 110 and a 2 nd connecting part 120 disposed at positions outside both ends in the width direction of the conveyance path 201, a pressing member 150 covering the conveyance path 201 in a desired range, and a 3 rd connecting part 130 and a 4 th connecting part 140 disposed at the 1 st end and the 2 nd end in the width direction of the pressing member 150, respectively. Here, the 1 st coupling part 110 and the 4 th coupling part 140 have the same structure, and the 2 nd coupling part 120 and the 3 rd coupling part 130 have the same structure.

The 1 st connecting part 110 is disposed on the 1 st end side in the width direction of the conveying path 201, i.e., on the left side, at a position intermediate between the inter-line slit device 225 and the cutting device 227. The 1 st coupling part 110 includes: a holding block 111, the holding block 111 standing in a direction orthogonal to the conveying surface of the conveying path 201; a rotary shaft 112 extending in the conveying direction of the conveying path 201, the rotary shaft 112 being rotatably disposed on the holding block 111; and a rotary block 113, the rotary block 113 being rotatable in the arrow a direction around the rotary shaft 112. As shown in fig. 2 and 3, the turning block 113 is provided with a concave portion 114, and the concave portion 114 is paired with a convex portion 132 disposed in the 3 rd coupling portion 130 of the pressing member 150, so that the convex portion 132 can be inserted and extracted, and the inserted convex portion 132 can be held.

As shown in fig. 4, 5A, 5B, and 5C, the recess 114 includes a concave hole 114A, a moving piece 114B, and an urging member 114C. The concave hole 114A is opened on one surface of the outer surface of the rotating block 113, and is formed to be able to receive an expanded diameter portion 132A of a projection 132 described later. As shown in fig. 5A, 5B, and 5C, a plurality of moving pieces 114B capable of reciprocating between a desired position on the center side of the opening surface and the outer peripheral edge (in the radial direction) are arranged on the opening surface of the recessed hole 114A in the circumferential direction of the opening surface. The moving piece 114B is disposed along the radial direction of the opening surface of the concave hole 114A, and is held by an urging member 114C, and the urging member 114C urges the moving piece 114B toward the center of the opening surface, and is represented by a rubber block or a spring.

As shown in fig. 5A, the innermost end edge of the moving piece 114B biased by the biasing member 114C is located inward of the maximum outer peripheral surface of the enlarged diameter portion 132A housed in the recessed hole 114A. As shown in fig. 5B, the diameter-enlarged portion 132A is inserted into the concave hole 114A and passes through the moving piece 114B while moving the moving piece 114B radially outward of the concave hole 114A against the biasing force of the biasing member 114C. Then, as shown in fig. 5C, the moving piece 114B is returned to the original position by the biasing force of the biasing member 114C, and the diameter-enlarged portion 132A can be prevented from coming out of the concave hole 114A (holding the diameter-enlarged portion 132A). As shown in fig. 5A, 5B, and 5C, the lower surface 114D (surface on the side of the concave hole 114A) of the moving piece 114B is preferably formed in a shape conforming to the outer shape of the enlarged diameter portion 132A so as to be in close contact with the enlarged diameter portion 132A when the enlarged diameter portion 132A is housed in the concave hole 114A.

The 2 nd connecting part 120 is disposed at a position facing the 1 st connecting part 110 on the 2 nd end side in the width direction of the conveying path 201, i.e., on the right side. The 2 nd coupling part 120 includes a base part 121 and a convex part 122 rising from the base part 121 in a direction orthogonal to the conveying surface of the conveying path 201. The distal end of the convex portion 122 is formed as an enlarged diameter portion 122A, and is held by an upright portion 122B that rises from the base portion 121. In the convex portion 122 of the present embodiment, the enlarged diameter portion 122A and the rising portion 122B are formed integrally. The enlarged diameter portion 122A is formed to be paired with the recess 144 of the 4 th coupling part 140 and to be insertable into and removable from the recess 144.

The 3 rd coupling part 130 has the same structure as the 2 nd coupling part 120. That is, the 3 rd coupling part 130 has a base 131 and a convex part 132 rising from the base 131 in the longitudinal direction of the pressing member 150. The distal end of the convex portion 132 is formed as an enlarged diameter portion 132A, and is held by an upright portion 132B that rises from the base portion 131. In the convex portion 132 of the present embodiment, the enlarged diameter portion 132A and the rising portion 132B are formed integrally. The diameter-enlarged portion 132A is formed to be paired with the recess 114 of the 1 st coupling part 110 and to be insertable into and removable from the recess 114. The 3 rd coupling portion 130 formed in this manner is attached to the left side of the pressing member 150 in the width direction of the conveyance path 201.

The recess 144 of the 4 th coupling part 140 has a concave hole 144A, a moving piece 144B, and an urging member 144C. The recess 144 of the 4 th coupling part 140 has the same structure as the recess 114 of the 1 st coupling part 110. Therefore, the structure of the recess 144 of the 4 th coupling part 140 will not be described herein because the reference numerals used to describe the structure of the recess 114 of the 1 st coupling part 110 in fig. 4, 5A, 5B, and 5C are given parenthesized reference numerals. The recess 144 of the 4 th coupling part 140 is attached by the screw N in a state of protruding from the upper surface of the pressing member 150, and the recess 144 can be used as a grip when the pressing member 150 is operated. The 4 th coupling part 140 thus formed is attached to the right side of the pressing member 150 in the width direction of the conveyance path 201.

As shown in fig. 6A and 6B, the pressing member 150 is formed as a rectangular parallelepiped block covering the entire width direction of the conveying path 201 and a partial range of the conveying direction. On the upper surface of the conveying path 201, projections 202 are formed at a plurality of positions at a desired interval in the width direction of the conveying path 201, and the projections 202 abut against the flat portion of the metal strip 240 while avoiding the projections of the metal strip 240, and extend in the conveying direction. On the lower surface 152 (the surface facing the conveying surface) of the pressing member 150, a plurality of projections 154 are arranged at a desired interval in the width direction of the conveying path 201, and the projections 154 are aligned with the positions where the projections 202 are arranged and abut on the flat portion of the metal strip 240. By adopting such a configuration, the metal strip 240 conveyed along the conveying path 201 is in a state where the flat portion is sandwiched by the protrusion 202 and the ridge 154. That is, the metal strip 240, which is formed as a long ruler having a product width, is formed with through holes and the like at any place, and is easily bent at the time of conveyance, can be conveyed to the cutting device 227 without being deformed or bent.

According to the structure of the thin-plate product pressing mechanism 100 described above, the pressing member 150 covering the upper surface of the conveyance path 201 in a desired range can be attached very easily. That is, from the state shown in fig. 2, the operator pushes the pressing member 150 in the direction of the arrow IV in fig. 2, thereby coupling the 3 rd coupling part 130 to the 1 st coupling part 110. Next, the operator rotates the pressing member 150 using the rotation shaft 112 of the 1 st coupling part 110 as a rotation shaft so that the lower surface 152 of the pressing member 150 faces the conveyance path 201, inserts the 2 nd coupling part 120 into the 4 th coupling part 140, and couples the 4 th coupling part 140 to the 2 nd coupling part 120. Thus, the operator can dispose the pressing member 150 alone on the conveyance path 201 without moving the pressing member 150 from the right position or the left position in the conveyance direction of the conveyance path 201 to the opposite side of the conveyance path 201. When the operator removes the pressing member 150 from the conveyance path 201, the procedure of attaching the pressing member 150 to the conveyance path 201 may be reversed.

The thin-plate product pressing mechanism 100 of the present invention has been described above based on the embodiments, and the technical scope of the present invention is not limited to the above embodiments. For example, in the thin-plate product pressing mechanism 100 of the above embodiment, the thin-plate product pressing mechanism 100 is disposed between the inter-row slit device and the cutting device of the press forming device 200, but the present invention is not limited to this configuration. The position of the thin-plate product pressing mechanism 100 is not particularly limited as long as it is a position that does not interfere with other devices on the conveyance path of the press forming device 200. That is, depending on the position where the thin plate product pressing mechanism 100 is disposed, a metal thin plate before being supplied to the die pressing portion or a metal strip which is press-molded into a predetermined shape by the die pressing portion may be a thin plate product. In addition, when the thin-plate product pressing mechanism 100 is disposed upstream of the die press section in the conveying direction, the lower surface of the pressing member may be formed as a flat surface.

In the thin-plate-product pressing mechanism 100 according to the present embodiment, the convex portions of the 1 st to 4 th coupling portions include so-called enlarged diameter portions and concave portions that can go over the enlarged diameter portions and can prevent coming-off, but the present invention is not limited to this form. For example, as shown in fig. 7, a concave portion 114(144) provided with two moving pieces 114B (144B) may be used, and the two moving pieces 114B (144B) may share a rotation shaft 114E (144E) and be biased in a direction of making contact with and separating from each other by a biasing member 114C (144C) made of a plate spring. The projections 132(122) may have the diameter-enlarged portions 132A (122A) that can be inserted into and pulled out from the recesses 114 (144). Further, as shown in fig. 7, when the roller 114F (144F) is disposed at the tip of the moving piece 114B (144B), the protruding portion 132(122) can be inserted into and removed from the recessed portion 114(144) more smoothly.

In addition, various modifications of the above-described embodiments may be combined with each other as appropriate.
