Abstract
The invention relates to a hardware punching die. The hardware punching die comprises an upper die plate used for clamping a metal plate to be machined and a stripper plate. The hardware punching die further comprises a punching needle used for puncturing the metal plate. The punching needle comprises a cylindrical punch, a conical punch fore part is arranged at the top end of the punch, and the taper angle of the punch fore part is 60-80 degrees. The upper die plate and the stripper plate are each provided with a cylindrical hole used for containing the punch. The connection section of the punch fore part and the punch is in a cone frustum shape, the diameter of the maximum cross section of the connection section is smaller than the diameter of the cross section of the punch, and the diameter of the minimal cross section of the connection section is equal to the diameter of the bottom of the punch fore part. The connection surface of the side face of the punch and the top end of the punch is a slope. The hardware punching die can effectively prevent the phenomenon that iron scraps are generated after the metal plate is punctured, the die is protected, the safety of workers is guaranteed during manual operation, and therefore the purpose of stable production is achieved.
Description
Technical field
The present invention relates to hardware dies field, more particularly, relate to a kind of hardware punching die.
Background technology
Along with the progress of science and technology, the various instrument used in our daily production, life and metallic plate, all have close relationship with mould.In the production process of some metallic plates, need that flange is carried out to metallic plate and puncture operation; At present used mould is punctured to metallic plate flange, puncturing red needle three corner degree is 120 degree, during mold work, metallic plate punching is worn by the drift that punctures relying on angle sharp, thus effect metallic plate being reached puncture, but metallic plate flange punctures and easily produces iron filings and drop, and iron filings drop and easily explode mould, especially, when manually producing, easily personal safety is endangered.
Summary of the invention
The technical problem to be solved in the present invention is, for the above-mentioned defect of prior art, provides the hardware punching die that the easy processing of a kind of safety is stable.
The technical solution adopted for the present invention to solve the technical problems is:
Constructing a kind of hardware punching die, wherein, comprising the cope match-plate pattern for clamping metallic plate to be processed and stripper plate, also comprise the red needle for the described metallic plate that punctures; Described red needle comprises cylindrical punch, and described punch tip is provided with portion of conical punch elder generation, and described drift elder generation portion's cone angle is 60-80 degree; Described cope match-plate pattern and described stripper plate offer respectively the cylindrical hole for holding described drift; The linkage section of portion of described drift elder generation and described drift is truncated cone-shaped, and the maximum cross section diameter of described linkage section is less than described drift cross-sectional diameter, and the minimum cross sectional diameter of described linkage section is equal with described drift elder generation portion's base diameter; The side of described drift and the joint face of described punch tip are inclined-plane.
Hardware punching die of the present invention, wherein, described linkage section and portion of described drift elder generation by basal diameter and cone that cone angle be 60-80 degree identical with described drift cross-sectional diameter be integrally processed into.
Hardware punching die of the present invention, wherein, described punch tip is provided with drift afterbody.
Hardware punching die of the present invention, wherein, described drift afterbody cross-sectional diameter is larger than described drift cross-sectional diameter.
Beneficial effect of the present invention is: have linkage section in the middle of portion of drift elder generation and drift, drift elder generation portion's cone angle is less simultaneously, man-hour is added to metallic plate, drift elder generation portion's subpunch wears metallic plate, and then carry out flange by drift, separate and rushing of metallic plate has been worn and flange these two operations, formed after metallic plate flange to puncture shape more smooth, effectively prevent the generation puncturing iron filings after metallic plate, protect mould, ensure that the safety of workman when manual operation, thus reach the object of steady production; Novel die processing is simple and easy, can directly simple and easy processing acquisition on original mould.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the hardware punching die implementation result schematic diagram of present pre-ferred embodiments.
Detailed description of the invention
The hardware punching die of present pre-ferred embodiments as shown in Figure 1, comprises the cope match-plate pattern 1 for clamping metallic plate 4 to be processed and stripper plate 2, also comprises the red needle 3 for the metallic plate 4 that punctures; Red needle 3 comprises cylindrical punch 31, and drift 31 top is provided with portion of conical punch elder generation 32, and portion of drift elder generation 32 cone angle is 60-80 degree; Cope match-plate pattern 1 and stripper plate 2 offer respectively the cylindrical hole for holding drift 31; Portion of drift elder generation 32 is truncated cone-shaped with the linkage section 33 of drift 31, and the cross-sectional diameter of linkage section 33 is less than drift 31 cross-sectional diameter, and the cross-sectional diameter of linkage section 33 is equal with portion of drift elder generation 32 base diameter; The side of drift and the joint face of punch tip are inclined-plane.Owing to having linkage section 33 in the middle of portion of drift elder generation 32 and drift 31, and drift elder generation portion's cone angle is less, add man-hour to metallic plate 4, portion of drift elder generation 32 subpunch wears metallic plate 4, and then carries out flange by drift 31, separate and rushing of metallic plate 4 has been worn and flange these two operations, formed after metallic plate 4 flange to puncture shape more smooth, effectively prevent the generation puncturing iron filings after metallic plate 4, protect mould, ensure that the safety of workman when manual operation, thus reach the object of steady production; Novel die processing is simple and easy, can directly simple and easy processing acquisition on original mould.
As shown in Figure 1, linkage section 33 and cone that cone angle be 120 degree identical with drift 31 cross-sectional diameter by basal diameter with portion of drift elder generation 32 is processed into, and Mould Machining is simple, directly can process acquisition, saved cost original use on drift.
As shown in Figure 1, drift 31 end is provided with drift afterbody 34.
As shown in Figure 1, drift afterbody 34 cross-sectional diameter is larger than drift 31 cross-sectional diameter.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
