Abstract

The utility model energy storage type perforating die, drives die shank to move downward by drive unit, and die shank drives upper bolster to move downward, and the upper mounted plate on upper bolster moves downward together.Because upper mounted plate is provided with the upper male mould coordinated with the lower cavity die on bottom plate, by the effect of upper lower punch, by workpiece blank.Moreover the butterfly spring up and down of setting, can carry out energy storage to the process of stamping-out, during to processing sheet workpiece, distortion and the damage of sheet workpiece itself can be avoided.The utility model can not affect the precision of cutting out, and can not cause the damage of mould.

Description

Energy storage type perforating die
Technical field
The utility model relates to punching, stamping-out, cuts, stamping-out, cut-out except cutting or the mould that uses of extruding, be specifically related to a kind of energy storage type perforating die.
Background technology
Blanking die is indispensable technological equipment in punching production, and good mould structure is the Reliable guarantee realizing process program.The quality of punching parts and precision height, depend primarily on quality and the precision of blanking die.Whether blanking die structure is reasonable, advanced, has a direct impact to production efficiency and the service life of blanking die itself and the safety, convenience etc. of operation.Due to blanking part shape, size, precision and production lot and working condition different, the structure type of blanking die is also different.Blanking die is mainly used in blanking and the stamping-out of various sheet material, the working position of mould is the cutting edge of punch and matrix, withstand shocks during cutting edge work power, shearing force, bending force, and shear the strong friction power of material, thus the performance requirement to die point is mainly referred to the performance requirement of blanking die.Cold punching die can be divided into Plate-Type Blanking Dies (thickness of slab≤1.5mm) and Blanking thick plank mould (thickness of slab > 1.5mm) two kinds.For the processing of sheet member, require that die steel has high wearability.But the easy shearing of the material of sheet member own, work in-process, often has larger effect and is applied in blanking die, cause loss and the waste of energy, and excessive blanking pressure can affect the precision of cutting out, and can cause the damage of mould.
Utility model content
The purpose of this utility model is to provide a kind of energy storage type perforating die, changes the structure of existing blanking die, adopts overall stamping-out mode to process, and ensures machining accuracy, be practically applicable to processing sheet workpiece.
For achieving the above object, the technical solution of the utility model is: energy storage type perforating die, comprise die shoe and upper bolster, two vertical guided mode bars are fixed with between described upper bolster and die shoe, described die shoe is provided with bottom plate, and described bottom plate is fixed with lower cavity die, and the upper surface of described lower cavity die is provided with workpiece slot, described bottom plate is also provided with trim ring, and described trim ring is positioned at the periphery of lower cavity die; Described upper bolster is fixed with die shank, the lower end of described upper bolster is fixed with upper mounted plate, fixed plate is fixed with upper male mould, the bottom of described upper male mould is provided with drift, described drift is corresponding with workpiece slot, the below described upper bolster being positioned at upper mounted plate is also provided with stripper, described stripper offers epirelief die cavity; Also disk spring is provided with between described die shank and upper mounted plate; The below of described die shoe is also provided with lower die shank, and described lower die shank is provided with baffle plate, is provided with lower butterfly spring between described baffle plate and die shoe.
When adopting technique scheme, drive die shank to move downward by drive unit, die shank drives upper bolster to move downward, and the upper mounted plate on upper bolster moves downward together.Because upper mounted plate is provided with the upper male mould coordinated with the lower cavity die on bottom plate, by the effect of upper lower punch, by workpiece blank.Moreover the butterfly spring up and down of setting, can carry out energy storage to the process of stamping-out, during to processing sheet workpiece, distortion and the damage of sheet workpiece itself can be avoided.The utility model can not affect the precision of cutting out, and can not cause the damage of mould.
Further, be also provided with a lower bolster between described bottom plate and die shoe, described lower bolster and bottom plate are fixed on die shoe by sunk screw.
Further, the size of described lower butterfly spring is greater than the size of butterfly spring.
Further, caging bolt is provided with between the end of described lower die shank and baffle plate.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model energy storage type perforating die embodiment.
Detailed description of the invention
As shown in Figure 1, the utility model energy storage type perforating die, comprise die shoe and upper bolster, two vertical guided mode bars are fixed with between described upper bolster and die shoe, die shoe is provided with bottom plate 1, bottom plate 1 is fixed with lower cavity die 2, and the upper surface of lower cavity die 2 is provided with workpiece slot, bottom plate 1 is also provided with trim ring 3, and trim ring 3 is positioned at the periphery of lower cavity die 2.Upper bolster is fixed with die shank, and the lower end of patrix 2 is fixed with upper mounted plate 4, upper mounted plate 4 is fixed with upper male mould 5, the bottom of upper male mould 5 is provided with drift, drift is corresponding with workpiece slot, and below upper bolster being positioned at upper mounted plate 4 is also provided with stripper 6, stripper 6 offers epirelief die cavity.Disk spring 7 is also provided with between die shank and upper mounted plate 4.The below of die shoe is also provided with lower die shank, and lower die shank is provided with baffle plate 8, is provided with lower butterfly spring 9 between baffle plate 8 and die shoe.Also be provided with a lower bolster between bottom plate 1 and die shoe, lower bolster and bottom plate 1 are fixed on die shoe by sunk screw.The size of lower butterfly spring 9 is greater than the size of butterfly spring 7.Caging bolt is provided with between the end of lower die shank and baffle plate.
In the utility model, drive die shank to move downward by drive unit, die shank drives upper bolster to move downward, and the upper mounted plate 4 on upper bolster moves downward together.Because upper mounted plate 4 is provided with the upper male mould 5 coordinated with the lower cavity die on bottom plate 1, by the effect of upper lower punch, by workpiece blank.Moreover the butterfly spring up and down of setting, can carry out energy storage to the process of stamping-out, during to processing sheet workpiece, distortion and the damage of sheet workpiece itself can be avoided.The utility model can not affect the precision of cutting out, and can not cause the damage of mould.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; without departing from the concept of the premise utility; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
