Abstract
The utility model relates to a punching die, which belongs to the field of machinery processing and comprises a forging die, wherein through holes are symmetrically arranged on two sides of a central line of the forging die, and the two symmetrically-arranged through holes are connected through a through hole groove. The through holes in the middle of the forging die are connected through the through groove so as to form a dumbbell-shaped hollow cavity, an integral forging die or an inserted type cutting edge combination structure forging die is adopted, and the integral forging die or an upper cutting edge and a lower cutting edge of the inserted type cutting edge all have a usable blade state, so that after a die part is processed, each forging die or each forging die cutting edge can be used twice. Using effect of the die is improved, and speed for replacing and adjusting of dies is increased. In the process for processing a die of a small workpiece, the forging die can be rejected after one-time use (double surfaces), and in the process for processing a die of a large workpiece, after one-time use (double surfaces), two-surface cutting edges can be used repeatedly after one-time repairing welding.
Description
Technical field
The utility model relates to a kind of punching concave die mould, belongs to field of machining.
Background technology
For general blanking die, no matter be that blanking die or perforating die all have a kind of like this part of die.Mould in use, no matter punch or die, the wearing and tearing of its cutting edge (make cutting edge partly wear and tear for radiussed or the angle of collapsing strong) be inevitable; Always influence the surface quality of stamping-out effect and workpiece this moment; Therefore, to the repairing of mould, mainly be to reparation protruding, the cutting edge of die state.In the repairing of routine, generally all adopts to fall to repairing or the method for repair welding, recover protruding, cutting edge of die state, reach the instructions for use of mould, the cycle that repairs a die is long, the expense height.
Summary of the invention
The purpose of the utility model is to provide the result of use that can improve mould, accelerates to change and the adjustment mould speed, has reduced mould repair, and production cost is low, and a kind of punching concave die mould of two-sided use cutting edge die.
Technical solution:
The utility model comprises: the forging mould, and the line bilateral symmetry is provided with through hole in forging mold center, and two symmetrically arranged through holes connect through through-hole groove.
Two symmetrically arranged through holes are connected to form the dumb-bell shape cavity by through-hole groove.
The utility model is connected to form the dumb-bell shape cavity at the two through hole at forging middle part by through-hole groove; Adopt the combining structure forging mould of solid forging mould or inserted cutting edge; Make solid forging mould or inserted cutting edge above and below cutting edge all have spendable cutting edge state; Therefore, after the mould parts processing, every forging mould or forging die point have the chance of twice use.Not only improve the result of use of mould, accelerated to change and adjust the speed of mould simultaneously.In the mould of processing than small workpiece, the forging mould can be once to scrap after (two-sided) uses, and in the mould of the big workpiece of processing, the forging mould can be once after (two-sided) uses, to reuse behind repair welding of two-sided cutting edge.

Specific embodiment
See Fig. 1, Fig. 2; The utility model is provided with in forging mould 1 center line bilateral symmetry and forms the dumbbell shaped cavity after through hole 2, two symmetrically arranged through holes 2 are connected by through-hole groove 3, and gross weight needs die-cut in completion forging molding metapore bottom; During use forging mould 1 is placed on the die shoe; Die shoe is installed on the forcing press base plate, and the descending completion of press ram that formpiston is housed is to after forging gross weight die-cut, in the formpiston backhaul; Stripper unloads the drift of forging from formpiston, accomplishes the punch work of a workpiece.After the production some, (A face) normal wear is to can not use the time above the cutting edge of forging mould 1, and after forging mould 1 unloaded, top and bottom turned over and are contained in the mould, use (B face) cutting edge of forging mould 1.
