Abstract

The utility model discloses a dual-part blanking mould. The dual-part blanking mould comprises an upper mould seat (1), a connecting plate (2), a fixing plate (3), a convex mould (4), a buffer plate (5), a discharge plate (6), a concave mould (7), a lower mould seat (8) and a blanking mechanism, wherein two mold cavities are formed in the concave mould (7) and staggered left and right in the blanking route direction; mold cores matched with the two mold cavities are arranged on the convex mould (4); the maximal distance between the two mold cavities in the blanking route direction is less than that of single mold cavity in the blanking route direction by two times; and the maximal distance between the two mold cavities in the direction perpendicular to the blanking route direction is less than that of single mold cavity in the direction perpendicular to the blanking route direction by two times. Due to the adoption of the dual-part blanking mould, the production efficiency of cold punch work can be improved and the utilization rate of plates can be increased.

Description

A kind of pair of part blanking die
Technical field
The utility model relates to a kind of pair of part blanking die.
Background technology
The various parts that are used for automobile, for example rear overhang is hung cover plate, seal washer, the skeleton etc. that suspends, and generally adopts the cold stamping operation scheme.Generally speaking, the single-piece blanking die is adopted in the cold stamping operation, at finished product of a cold stamping operation moulding.In the single-piece blanking forming, the general symmetrical arrangement of product is in the axis both sides of sheet material, and is as shown in Figure 1, is the structural representation of sheet material after the moulding of rear overhang extension cover plate.Conspicuous, single-piece cold stamping operation in the prior art, a cold stamping are also done can only finished product of moulding, and production efficiency is lower, can not satisfy the demand of extensive operation; On the other hand, finished product generally only is distributed in the middle part of sheet material, and the sheet material of both sides is by as waste disposal, sheet material is not fully arranged and is utilized, thereby cause the utilization rate of sheet material lower, has improved the processing cost of product.For this reason, in the current sheet size remains unchanged, how to improve the production efficiency of cold stamping operations, improve the utilization of sheet metal has become skilled Zheng technical problems to be solved.
The utility model content
To the problem that prior art exists, the purpose of the utility model is to propose a kind of pair of part blanking die, adopts this pair part blanking die can improve the production efficiency of cold stamping operation, and improves the utilization rate of sheet material.
For reaching this purpose, the utility model adopts following technical scheme:
A kind of pair of part blanking die; Comprise upper bolster, connecting plate, fixed head, punch, buffer board, stripper, die, die shoe and blanking mechanism; Wherein, connecting plate is fixed on the below of cope match-plate pattern, and punch is fixed on the below that connects this through fixed head; Stripper is installed in the periphery of punch and can moves up and down along punch, and buffer board is arranged between fixed head and the stripper; Die be fixed on die shoe on; Blanking mechanism is arranged between upper bolster, the die shoe and moves up and down with respect to die shoe with the control upper bolster; Two die cavities are set on die, and said two die cavities are interlaced arrangement along the blanking stroke directions left and right sides, on punch, is provided with and said two cores that die cavity matches; In the blanking stroke directions, the ultimate range between two die cavities is less than the twice of single die cavity in this direction ultimate range, and perpendicular to the blanking stroke directions, the ultimate range between two die cavities is less than the twice of single die cavity in this direction ultimate range.
Preferably, said blanking mechanism is the blanking oil cylinder that is arranged between upper bolster, the die shoe.
Preferably, said buffer board plate is a rubber bodies.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
The utility model provides a kind of pair of part blanking die, two die cavities and the core match are set on die and punch, a cold working operation can two finished products of moulding, and production efficiency has been improved twice, satisfy the demand that can not satisfy extensive operation; On the other hand, one-time formed two finished products only are evenly distributed on the both sides, axis of sheet material, and sheet material is carried out abundant reasonable use, have improved the utilization rate of sheet material, have reduced the processing cost of product.
Description of drawings
Fig. 1 is a structural representation of hanging sheet material behind the cover plate single-piece blanking forming in the prior art for rear overhang.
Fig. 2 is the structural representation of a kind of pair of part blanking die of the utility model proposition.
Fig. 3 is the structural representation of die upper impression among Fig. 2.
Fig. 4 carries out the structural representation that rear overhang is hung sheet material behind the cover plate pair part blanking formings for the two part blanking dies that adopt Fig. 2.
The specific embodiment
Further specify the technical scheme of the utility model below in conjunction with accompanying drawing and through the specific embodiment:
As shown in Figure 2, the structural representation of a kind of pair of part blanking die that proposes for the utility model.Fig. 3 is the structural representation of die upper impression among Fig. 2.Fig. 4 carries out the structural representation that rear overhang is hung sheet material behind the cover plate pair part blanking formings for the two part blanking dies that adopt Fig. 2.
With reference to accompanying drawing, a kind of pair of part blanking die that the utility model proposes comprises upper bolster 1, connecting plate 2, fixed head 3, punch 4, buffer board 5, stripper 6, die 7, die shoe 8 and blanking mechanism; Wherein, Connecting plate 2 is fixed on the below of cope match-plate pattern 1, and punch 4 is fixed on through fixed head 3 and connects this below of 2, and stripper 6 is installed in the periphery of punch 4 and can moves up and down along punch 4; Buffer board 5 is arranged between fixed head 3 and the stripper 6, and said buffer board plate 5 is a rubber bodies.Die 7 be fixed on die shoe 8 on; Blanking mechanism is arranged between upper bolster 1, the die shoe 8; Being used to control upper bolster 1 moves up and down to move downward and cooperate in die 7 with control punch 4 with respect to die shoe 8 and accomplishes the blankings action; Preferably, said blanking mechanism is the blanking oil cylinder 9 that is arranged between upper bolster 1, the die shoe 8.Two die cavities 71 are set on die 7, and said two die cavities 71 are interlaced arrangement along the blanking stroke directions left and right sides, and the core 41 that matches with said two die cavities 71 is set on punch 4; In the blanking stroke directions, the ultimate range between two die cavities 71 is less than the twice of single die cavity 71 in this direction ultimate range, and perpendicular to the blanking stroke directions, the ultimate range between two die cavities 71 is less than the twice of single die cavity 71 in this direction ultimate range.
The utility model provides a kind of pair of part blanking die, two die cavities and the core match are set on die and punch, a cold working operation can two finished products of moulding, and production efficiency has been improved twice, satisfy the demand that can not satisfy extensive operation; On the other hand, one-time formed two finished products only are evenly distributed on the both sides, axis of sheet material, and sheet material is carried out abundant reasonable use, have improved the utilization rate of sheet material, have reduced the processing cost of product.
