Abstract
The utility model discloses a plunger chip for punching which comprises a cylindrical plunger chip body (1). A lead angle (3) is arranged on the periphery of the bottom of the plunger chip body (1), a positioning cone (2) which is integrally formed with the plunger chip body (1) is arranged at the center of the bottom of the plunger chip body (1), and a wear-resistant coating is arranged on the positioning cone (2). According to the plunger chip for punching, machining accuracy is improved due to the fact that the positioning cone is arranged at the bottom, service life of the plunger chip for punching is prolonged due to the fact that the wear-resistant coating is arranged on the positioning cone, and burrs are not prone to appearance on the periphery of a punching hole due to the fact that the lead angle is arranged on the periphery of the bottom of the plunger chip. The plunger chip for punching is capable of improving rate of finished products, simple in design and convenient to achieve, thereby having good application prospect.
Description
Technical field
The utility model relates to the Stamping Die Technology field, is 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 appears in the edge of stamping surface easily, causes processing bad, substandard products occur, affect yield rate.
The utility model content
The purpose of this utility model 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 realizes easily, has a good application prospect.
In order to achieve the above object, the technical scheme that adopts of the utility model 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 beneficial effects of the utility model are: pierce punch of the present utility model, 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, realize easily, have a good application prospect.
Description of drawings
Fig. 1 is the structural representation of pierce punch of the present utility model.
Fig. 2 is the vertical section figure of pierce punch of the present utility model.
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 utility model is further described.
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, the utility model simplicity of design, realize easily, have a good application prospect.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
