Abstract
The invention discloses a piercing punch, comprising a cylindrical punch body (1). The bottom edge of the punch body (1) is provided with a lead angle (3). The bottom center of the punch body (1) is provided with a positioning cone (2) which is integrally formed with the punch body (1). The positioning cone (2) is provided with a layer of wear-resistant coating. According to the piercing punch, the bottom of the piercing punch is provided with the positioning cone, so that the processing accuracy is improved; the positioning cone is provided with a layer of wear-resistant coating, so that the service life of the piercing punch is prolonged; and the bottom edge of the punch body is provided with the lead angle, so that the edge of a stamping hole is not bristly, and the rate of finished products is improved. The piercing punch also has the advantages of simple design, simplicity in realization and good applying prospect.
Description
Technical field
The present invention relates to the Stamping Die Technology field, be specifically related to a kind of pierce punch.
Background technology
At present, in the stamping parts manufacture process, a lot of processing to the hole can appear, and require also more and more higher to the accuracy of position, the normal pierce punch that adopts moves down in the prior art, keeps and position consistency to be processed, and this locating effect is bad, error is larger, it is cylindrical also having existing pierce punch, and burr easily appears in the edge of stamping surface, causes processing bad, substandard products occur, affect yield rate.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, the pierce punch that provides, bottom are provided with the location cone, improve the accuracy of hole processing, and the location cone is provided with one deck wear-resistant coating, prolong its service life, and be provided with lead angle at the bottom margin of punch body, make the punching hole edge burr not occur, improve yield rate, simplicity of design easily realizes, has a good application prospect.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of pierce punch comprises columniform punch body, it is characterized in that: the bottom margin of described punch body is provided with lead angle, and the bottom centre place of establishing of described punch body is provided with and the integrated location of punch body cone, and described location cone is provided with one deck wear-resistant coating.Aforesaid a kind of pierce punch is characterized in that: described wear-resistant coating is WC/12Co coating or Cr3C2/NiCr coating.
Aforesaid a kind of pierce punch is characterized in that: the top post jamb of described punch body also is provided with anti-slip veins.
The invention has the beneficial effects as follows: pierce punch of the present invention, the bottom is provided with the location cone, improve the accuracy of hole processing, and the location cone is provided with one deck wear-resistant coating, prolongs its service life, and the bottom margin at punch body is provided with lead angle, make the punching hole edge burr not occur, improve yield rate, simplicity of design, easily realize, have a good application prospect.
Description of drawings
Fig. 1 is the structural representation of pierce punch of the present invention.
Fig. 2 is the vertical section figure of pierce punch of the present invention.
The mark implication of accompanying drawing is as follows:
1: punch body; 2: the location cone; 3: lead angle; 4: anti-slip veins.
The specific embodiment
Below in conjunction with Figure of description, the present invention is further illustrated.
As shown in Figure 1, a kind of pierce punch, comprise columniform punch body 1, the top post jamb of punch body 1 also is provided with anti-slip veins 4, makes things convenient for pierce punch to be installed on the stamping machine, start anti-skidding effect, the bottom margin of punch body 1 is provided with lead angle 3, guarantees that burr does not appear in the punching hole edge, improves yield rate, the bottom centre place of establishing of punch body 1 is provided with and punch body 1 integrated location cone 2, location cone 2 is provided with one deck wear-resistant coating, and wear-resistant coating is WC/12Co coating or Cr3C2/NiCr coating, can improve location cone 2 wearabilities, prolong its service life, in the course of the work, adjust pierce punch by stamping machine and move down, location cone 2 is depressed into the center in hole to be processed, registration, then carry out punching press, improving the accuracy of hole processing, simplicity of design of the present invention, easily realize, have a good application prospect.
Above demonstration and described basic principle of the present invention, principal character and advantage.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is by appending claims and equivalent circle thereof.
