Abstract

The utility model provides a punch die which comprises an upper die and a lower die and is characterized by further comprising an upper die holder and a lower die holder, wherein a groove is formed in the middle of the lower die holder, and a guide rod with a spring is arranged in the groove; the lower die is positioned in the groove, and a guide groove matched with the guide rod is formed in the lower die; a guide post is arranged on the lower die holder, and a guide sleeve matched with the guide post is arranged on the upper die holder; the upper die is fixed to the upper die holder through a screw. According to the punch die, the upper die holder and the lower die holder are additionally provided and are positioned through the guide post and the guide sleeve, and small shifting is arranged between the upper die and the lower die; meanwhile, a raw material is shifted in the punching process due to the arrangement of the lower die holder, and the punching precision is increased. The spring arranged at the lower die and the lower die holder is utilized; therefore, on one hand, the impact force of the upper die on the lower die is buffered, and the service life of the lower die is prolonged, and on the other hand, the position of a part is higher after machining, the part can be conveniently taken off from the lower die, and the working efficiency is improved.

Description

A kind of die for punching machine
Technical field
The utility model belongs to processing equipment technical field, relates in particular to a kind of die for punching machine.
Background technology
Stamping technology is to manufacture the interior very important technology of specialty, is that the plate to being placed in mould applies deformation force, makes plate in mould, produce distortion, thereby obtains the product parts technology of definite shape, size and performance.Existing pressing equipment generally comprises drive unit, upper die and lower die, utilizes drive unit to drive patrix to move down with counterdie and has matched to raw-material punching press.But in punching course, between patrix and lower intermode, mould and raw material, easily there is displacement, affect crudy, cause percent defective higher, and the parts that process are also not easy to take out from counterdie.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of die for punching machine, comprise upper die and lower die, characterized by further comprising upper bolster and die shoe, described die shoe middle part is provided with groove, in described groove, be provided with the guide rod with spring, described counterdie is positioned at described groove, which is provided with the guide groove mating with described guide rod, and described die shoe is provided with lead, described upper bolster is provided with the fairlead coordinating with described lead, and described patrix is fixed on described upper bolster by screw.
More than one of the quantity of described lead, the diameter of described spring is greater than the diameter of described guide groove.
The beneficial effects of the utility model are: install upper bolster and die shoe additional, and utilize lead and fairlead to locate, place patrix and lower intermode and occur small displacement, the setting of die shoe simultaneously has also been placed raw material and has been shifted in punching course, improve punching precision, improved the crudy of product; Utilization is arranged on the spring of counterdie and die shoe, has cushioned the impulsive force of patrix to counterdie on the one hand, has extended the service life of counterdie, and after another convenient processing, the position of parts is higher, is convenient to take out from counterdie, has improved operating efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
In figure, 1, patrix; 2, counterdie; 3, upper bolster; 4, die shoe; 5, guide rod; 6, spring; 7, guide groove; 8, lead; 9, gathering sill.
As shown in Figure 1, die shoe 4 middle parts are provided with groove, in groove, be provided with the guide rod 5 with spring 6, counterdie 2 is positioned at groove, which is provided with the guide groove 7 mating with guide rod 5, and die shoe 3 is provided with lead 8, upper bolster 3 is provided with the fairlead 9 coordinating with lead 8, patrix 1 is fixed on upper bolster 3 by screw, more than one of the quantity of lead 8, and the diameter of spring 6 is greater than the diameter of guide groove 7.
Have been described in detail of the present utility model by embodiment above, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
