Abstract
The utility model relates to a special purpose punching head used for perforating on leather, which is a metal rod with the tapered front end. An opening is arranged on a tapered front end surface. The opening and the tapered surface form a knife edge. The utility model has the technical scheme proposal that the waist of the metal rod is provided with a drilling hole which is mutually communicated with the opening which is arranged on the front end of the metal rod. The leather perforating punch of the utility model can complete processing just using a simple drilling machine, with the advantages of low processing cost, small volume occupation of the drilling hole, and little reduction of punch strength, compared with a milling groove.
Description
Affiliated technical field
The utility model relates to a kind of special punch that is used for punching on leather.
Background technology
Leather punching punching pin is that a front end is the metal bar of taper, is provided with perforate at the tapered front end face, and this perforate and conical surface form blade, are used for cutting hides.Existing a kind of leather punching punching pin also is provided with a groove milling in its side, this groove milling and front end perforate connect mutually, and the leather waste under preceding terminal knife edge cutting is discharged by this groove milling by perforate.But the difficulty of processing of groove milling is big, and the cost of processing height, and simultaneously, groove milling technology is bigger to the diameter requirement of punching pin, and therefore for this structure of undersized punching pin and inapplicable, the length of groove milling simultaneously is long, and the intensity of punching pin is reduced.
Summary of the invention
The purpose of this utility model is to overcome the above-mentioned defective of prior art, provides a kind of tooling cost low, and intensity is big, the material of waste discharge simultaneously leather punching easily punching pin.
The utility model is that a front end is the metal bar of taper, is provided with perforate at the tapered front end face, and this perforate and conical surface form blade, and its technical solution is that the waist at metal bar offers boring, and the perforate of this boring and front end connects mutually.
Adopt the leather punching punching pin of said structure only need use simple drilling machine can finish processing, tooling cost is very cheap, and the shared volume of holing simultaneously is little, and is also little a lot of to the reduction of punching pin intensity with respect to groove milling.
Description of drawings
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of present embodiment.
Embodiment
As shown in the figure, present embodiment is that a front end is the metal bar 1 of taper, is provided with perforate 2 at the tapered front end face, and this perforate 2 forms blade 3 with conical surface, and the waist at metal bar 1 is provided with circular bore 4 simultaneously, and this boring 4 connects mutually with the perforate 2 of front end.In the present embodiment, boring 2 opening is positioned on the conical surface, can shorten waste material like this by the distance that cuts to discharge, but knife edge part intensity influenced meeting more greatly.If the opening of boring is opened on the cylindrical surface, increased though waste material cuts to the distance of eliminating again, boring to knife edge part intensity to influence meeting little a lot.
Claims (3)
1, a kind of leather punching punching pin, front end is the metal bar of taper, is provided with perforate at the tapered front end face, and this perforate and conical surface form blade, and it is characterized in that: the waist at metal bar offers boring, and the perforate of this boring and front end connects mutually.
2, leather punching punching pin according to claim 1, it is characterized in that: the opening of described boring is positioned on the conical surface of punching pin front end.
3, leather punching punching pin according to claim 1, it is characterized in that: the opening of described boring is positioned on the cylindrical surface of punching pin rear end.
