Abstract
The invention discloses a punch device with a changeable punch, which comprises a punch holder and the punch. A punch groove is arranged in the punch holder, positioning slots are arranged on the inner wall of the punch groove and respectively in the shape of labyrinth with three right-angles and extend from the end opening of the punch groove to the inside of the punch groove, the punch is provided with a cylindrical fastening block, the cylindrical fastening block is provided with positioning fasteners, and the punch is fixed into the punch groove by the aid of the positioning fasteners matched with the positioning slots in the punch holder. By the design of the labyrinth with three right-angles, the punch is changeable on the basis of the original punch structure, while effect of the punch cannot be affected during use, and accordingly the problem that the punch is discarded integrally after being damaged is solved well, cost and resources are saved and utilization rate of materials is increased.
Description
Technical field
The present invention relates to a kind of punch device, relate in particular to a kind of punch device that changes head.
Background technology
In the process of alloying product, need use decompressor, can use drift in the decompressor, drift carries out punching press to workpiece; The existing drift that is used for decompressor becomes one; It is used for workpiece is added man-hour, and the position that drift contacts with workpiece is prone to bigger damage, because of drift is integrated; Its local damage has been scrapped with regard to integral body; And the drift that is used for decompressor generally adopts alloy steel cost bigger, in case scrap the raising that will cause production cost, the waste of resource.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of punch device that changes head.
Technical solution of the present invention is achieved in that a kind of punch device that changes head, comprises punch holder and drift, offers the drift groove in the said punch holder; Said drift groove inwall is provided with detent; Said detent is right-angled bend shape labyrinth-like three times, and extends to drift groove inside from drift groove port; Said drift is provided with the cylinder fixture block; Said cylinder fixture block is provided with the location dop; During installation, drift is fixed in the detent in the punch holder through the location dop.
Preferably, said detent, location dop have 4 respectively.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
A kind of punch device that changes head of the present invention; Through the design of three right-angled bend shape labyrinth-like, on original punch structure, make drift realize and to change; Do not influence drift effect in use again; Well solve drift and damaged the problem that back integral body is scrapped, provided cost savings and resource the rate that makes full use of of the material of raising.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is a kind of structural perspective of changing the punch device of head of the present invention;
Accompanying drawing 2 is a kind of cutaway view that changes the punch device of head of the present invention;
Wherein: 1, punch holder; 2, drift; 3, drift groove; 4, detent; 5, cylinder fixture block; 6, location dop.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 1-2 is a kind of punch device that changes head of the present invention, comprises punch holder 1 and drift 2, offers drift groove 3 in the said punch holder 1; Be provided with four detents 4 of circular array in the said drift groove 3; Said detent 4 is right-angled bend shape labyrinth-like three times, extends to the inside of drift groove 3 from the port of drift groove 3; Said drift 2 is provided with cylinder fixture block 6; Four location dops 6 that match with detent 4 of annular array on the said cylinder fixture block 6; During installation, drift 2 is fixed in the detent 4 in the punch holder 1 through location dop 6.Through the design of three right-angled bend shape labyrinth-like, on original punch structure, after being damaged, drift can disassemble; Only need change the forward part of drift and get final product; And need not integral body change, do not influence drift effect in use again, solve drift and damaged the problem that back integral body is scrapped; Provide cost savings and resource the rate that makes full use of of the material of raising.
The foregoing description only is explanation technical conceive of the present invention and characteristics; Its purpose is to let the personage that is familiar with this technology can understand content of the present invention and implements; Can not limit protection scope of the present invention with this; All equivalences that spirit is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
Claims (2)
1. the punch device that can change head comprises punch holder and drift, it is characterized in that: offer the drift groove in the said punch holder; Said drift groove inwall is provided with detent; Said detent is right-angled bend shape labyrinth-like three times, and extends to drift groove inside from drift groove port; Said drift is provided with the cylinder fixture block; Said cylinder fixture block is provided with the location dop; During installation, drift is fixed in the detent in the punch holder through the location dop.
