Abstract

The utility model relates to a die with a detachable punch, comprising a male die substrate, a compression screw, a punch and a gasket. Two location holes are symmetrically disposed at the left and right of the male die substrate. The punch is embedded in the male die substrate. The gasket is disposed between the male die substrate and the punch. The compression screw fastens the punch through the location holes. The bottom end of the punch is a blade. The male die substrate is made from Cr12MoV. The blade part is made from tungsten tungsten and cobalt cemented carbide. As the male die substrate is fixed to the punch through the compression screw and the wearing speed of the blade is fast, when the blade is worn, it is only required to replace the punch, reducing waste cased by integrating the male die substrate and the punch.

Description

The removable mould of a kind of drift
Technical field
The utility model relates to a kind of mould, refers in particular to the conveniently detachable mould of a kind of drift, belongs to the punching machine mold design field.
Background technology
In existing punching machine mold, drift is that one is connected with the punch matrix, and after the blade wearing and tearing of punch, whole punch is scrapped and can not be used, and the punch that need more renew because the manufacturing cost of mould is higher, has so just caused very big waste.
The utility model content
The utility model purpose is to provide a kind of drift removable mould for the deficiency that overcomes prior art.
For achieving the above object, the technical scheme that the utility model adopts is: the removable mould of a kind of drift comprises punch matrix, housing screw, drift, pad; Be symmetrically set with two locating holes on the said punch matrix; Said drift embeds and is installed on the punch matrix; Between said punch matrix and the drift pad is installed; Said housing screw is fixed drift through locating hole; The bottom of said drift is a blade.
Preferably, the material of said punch matrix is Cr 12MoV.
Preferably, the material of said knife edge part is a tungsten-cobalt hard alloy.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The removable mould of a kind of drift of the utility model scheme; Fixing between punch matrix and the drift through housing screw, because the rate of wear of blade is very fast, during to the blade wearing and tearing; Only just can with changing drift; Reduced the waste that causes because of punch matrix and drift one,, prevented the phenomenon that fractures that in the stamping-out process, causes because of punch diameter is less owing between drift and the punch matrix pad is installed.
Description of drawings
Below in conjunction with accompanying drawing the utility model technical scheme is described further:
Accompanying drawing 1 is the cutaway view of front view of the removable mould of a kind of drift of the utility model;
Wherein: 1, punch matrix; 2, locating hole; 3, housing screw; 4, drift; 5, blade; 6, pad.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The removable mould of the described a kind of drift of the utility model shown in accompanying drawing 1 comprises punch matrix 1, housing screw 3, drift 4, pad 6; The material of said punch matrix 1 is Cr 12MoV; Be symmetrically set with two locating holes 2 on the said punch matrix 1; Said drift 4 embeds and is installed on the punch matrix 1; Between said punch matrix 1 and the drift 4 pad 6 is installed; Said housing screw 3 is fixed drift 4 through locating hole 2; The bottom of said drift 4 is a blade 5; The material of said blade 5 parts is a tungsten-cobalt hard alloy.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The removable mould of a kind of drift of the utility model scheme; Fixing between punch matrix and the drift through housing screw, because the rate of wear of blade is very fast, during to the blade wearing and tearing; Only just can with changing drift; Reduced the waste that causes because of punch matrix and drift one,, prevented the phenomenon that fractures that in the stamping-out process, causes because of punch diameter is less owing between drift and the punch matrix pad is installed.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.

Claims (3)

1. the removable mould of drift is characterized in that: comprise punch matrix, housing screw, drift, pad; Be symmetrically set with two locating holes on the said punch matrix; Said drift embeds and is installed on the punch matrix; Between said punch matrix and the drift pad is installed; Said housing screw is fixed drift through locating hole; The bottom of said drift is a blade.
2. the removable mould of a kind of drift according to claim 1 is characterized in that: the material of said punch matrix is Cr 12MoV.
