Abstract

The utility model discloses a kind of blanking die of bending chain-plate, comprise upper die and lower die, patrix comprises push rod, insert push rod, die shank, die holder, top board, die, punch and ejector, described ejector has two highly different upper mounting plate faces, and sloped transition is passed through in these two upper mounting plate faces; Counterdie comprises stripper, punch-die, lower bolster, punch-die holder, and described punch-die has two the lower platform faces corresponding with two of ejector upper mounting plate faces, and two lower platform face height differences also pass through sloped transition; The bottom of described ejector and the top of punch-die have the profile corresponding to bending chain-plate.This programme is blanking bent integrated when stamping-out, and stamping-out carrier bar out just can omit bending process, enhances productivity.

Description

A kind of blanking die of bending chain-plate
Technical field
The utility model belongs to chain manufacturing technology field, particularly relates to a kind of blanking die of bending chain-plate.
Background technology
At present, some bending chain-plates all need first compound die blanking, then carry out bending process, need to design many molds, and need a lot of time to go to debug mould.Not only wasting manpower and material resources, and high concerning cost end user, and production efficiency is low.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of blanking die of bending chain-plate, the blanking bent integrated when stamping-out, and stamping-out carrier bar out just can omit bending process, enhances productivity.
To achieve the above object, the utility model have employed following technical scheme:
A kind of blanking die of bending chain-plate, comprise upper die and lower die, patrix comprises push rod, insert push rod, die shank, die holder, top board, die, punch and ejector, die is fixed on below die holder, die holder is fixed on below die shank, push rod is located in die shank and lower end can pushing tow insert push rod, top board to be arranged in die holder and to be moved up and down by insert push rod pushing tow, ejector is fixed on die, punch to be plugged in ejector and to realize carrier bar punching by top board pushing tow, described ejector has two highly different upper mounting plate faces, sloped transition is passed through in these two upper mounting plate faces, counterdie comprises stripper, punch-die, lower bolster, punch-die holder, punch-die holder is fixed on lower bolster, punch-die is fixed on punch-die holder, stripper is set in outside punch-die, described punch-die has two the lower platform faces corresponding with two of ejector upper mounting plate faces, and two lower platform face height differences also pass through sloped transition, the bottom of described ejector and the top of punch-die have the profile corresponding to bending chain-plate.
The utility model is owing to have employed above technical scheme, and carrier bar bending parameter and the profile of bending as required on the ejector and punch-die of mould are processed, and directly obtains the chain board size needed, without the need to carrying out bending process separately again after making stamping-out.Can ensure to complete bending while blanking by this series of Design of Dies and process modification.Eliminate bending process, the employee work time can be reduced by this programme, enhance productivity.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.
Embodiment 1:
As Fig. 1, the blanking die of a kind of bending chain-plate shown in Fig. 2, comprise upper die and lower die, patrix comprises push rod 1, insert push rod 2, die shank 3, die holder 4, top board 5, die 6, punch 7 and ejector 12, die 6 is fixed on below die holder 4, die holder 4 is fixed on below die shank 3, push rod 1 is located in die shank 3 and lower end can pushing tow insert push rod 2, top board 5 to be arranged in die holder 4 and to be moved up and down by insert push rod 2 pushing tow, ejector 12 is fixed on die 6, punch 7 to be plugged in ejector 12 and to realize carrier bar punching by top board 5 pushing tow, as Fig. 3 a, 3b, shown in 3c, described ejector 12 has two highly different upper mounting plate faces, sloped transition is passed through in these two upper mounting plate faces, counterdie comprises stripper 8, punch-die 9, lower bolster 10, punch-die holder 11, punch-die holder 11 is fixed on lower bolster 10, punch-die 9 is fixed on punch-die holder 11, stripper 8 is set in outside punch-die 9, as shown in Fig. 3 a, 3b, 3c, described punch-die 9 has two the lower platform faces corresponding with two of ejector 12 upper mounting plate faces, and two lower platform face height differences also pass through sloped transition, the bottom of described ejector 12 and the top of punch-die 9 have the profile corresponding to bending chain-plate.
In the present embodiment, carrier bar bending parameter and the profile of most importantly bending as required on the ejector and punch-die of compound die are processed, and directly obtain the chain board size needed, without the need to carrying out bending process separately again after making stamping-out.In blanking process, as long as conveniently compound die stamping-out, ejector and punch-die cooperatively interact and directly complete blanking and bending, this bending blanking method, original basis eliminates press-bending operation of making a detour, has saved processing cost, improving production efficiency and product quality.
It is emphasized that: be only preferred embodiment of the present utility model above, not any pro forma restriction is done to the utility model, every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
