Present mould is adding man-hour to left back longeron, the material of punching press out in side cut line department is flat curved surface, the material can be stretched to two during the turn-ups and pull the attenuation until the fracture, cause scrapping of tablet, the success rate of mould processing has seriously been influenced, in addition add man-hour to preceding floor rear frame member again, the required material of reserving of back process turn-ups is not had in the department of cutting edge of part, turn-ups part department of bending reserves the material not enough, lead to the fracture problem to cause preceding floor rear frame member turn-ups to frequently appear the fracture, we provide one kind for this reason and prevent that the punching press product from cracking the improved generation stamping die structure who corrugates.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model provides a prevent punching press product fracture improved generation stamping die structure that corrugates has solved the problem of proposing among the above-mentioned background art.
In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a prevent improved generation stamping die structure of punching press product fracture wrinkling, includes longeron stamping die, preceding floor back beam stamping die, tablet behind left side, longeron stamping die's upper surface is provided with the terrace die behind a left side, longeron stamping die's lower surface is provided with the die behind a left side, the die upper surface is provided with longeron mould technology convex closure, the quantity of longeron mould technology convex closure is four.
Optionally, the bottom of the front floor rear cross beam stamping die is fixedly connected with a cross beam die process convex hull, the front of the front floor rear cross beam stamping die is provided with a fixing hole, the front of the front floor rear cross beam stamping die is provided with three fixing claws, and the number of the fixing claws is three.
Optionally, a clamping groove is formed in the left side of the material sheet, and a groove is formed in the clamping groove.
The utility model provides a prevent improved generation stamping die structure that punching press product ftractures and corrugates possesses following beneficial effect:
1. this prevent improved generation stamping die structure of punching press product fracture wrinkling through set up longeron mould technology convex closure on left back longeron stamping die, when carrying out the turn-ups to left back longeron sheet material, owing to be provided with longeron mould technology convex closure and can supply the material of material limit extension department, avoids the excessive attenuation of material, prevents that the condition of material fracture from taking place.
2. This prevent improved generation stamping die structure of punching press product fracture wrinkling through set up crossbeam mould technology convex closure behind the front floor on crossbeam stamping die, there is surplus material in the protruding closure department of crossbeam mould technology after the side cut is accomplished, when carrying out the turn-ups to front floor rear beam sheet material, avoids the too thin-down of material, the fracture condition, through this improvement, has stopped the turn-ups fracture bad phenomenon.
