Problems solved by technology

[0002] In the process of manufacturing alloy products, a stamping device is required. A punch is used in the stamping device. The punch punches the workpiece. The existing punch used for the stamping device is integrated. It is used for processing the workpiece. , the contact between the punch and the workpiece is prone to greater damage. Because the punch is integrated, if it is partially damaged, it will be scrapped as a whole and cannot be used. The whole punch must be replaced, which will affect the processing and production, waste time and affect production efficiency.

Embodiment Construction

[0011] The present invention is described below in conjunction with accompanying drawing.

[0012] attached Figure 1-2 It is a punch device according to the present invention, comprising a punch seat 1 and a punch 2, the punch seat 1 is provided with a punch groove 3; the inner wall of the punch groove 3 is provided with threads; The punch 2 is composed of two symmetrical heads and a fixed cylinder 4; the fixed cylinder 4 is connected to the punch groove 3 through threads; the design of the double-head replaceable punch is matched with the screw connection to make the punch Realize a separate structure, so that when one head of the punch is damaged during use, it is not necessary to replace the punch device as a whole, just unscrew the punch, and replace it with another head for production and use again, without the need to replace the whole immediately Lose.

[0013] The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the ...

Abstract

The invention discloses a punch device comprising a punch holder and a puncher pin, wherein the punch holder is internally provided with a punch groove; the inner wall of the punch groove is provided with a thread; the puncher pin consists of two symmetrical heads and a fixed cylinder; and the fixed cylinder is in threaded connection with the punch groove. According to the scheme, the puncher pin realizes a detachable structure by the design of the replaceable puncher pin with double heads and through the threaded connection, therefore, when one head of the punch is damaged in use, only the damaged head is screwed down to be replaced by another head without integrally replacing the punch device, so that the punch device can be used again for production. The punch device does not need to be integrally replaced immediately; the problem that the puncher pin, if damaged, needs to be replaced immediately is well solved; and time and capital are saved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a device, in particular to a punch device. Background technique [0002] In the process of manufacturing alloy products, a stamping device is required. A punch is used in the stamping device. The punch punches the workpiece. The existing punch used for the stamping device is integrated. It is used for processing the workpiece. , the contact between the punch and the workpiece is prone to greater damage. Because the punch is integrated, if it is partially damaged, it will be scrapped as a whole and cannot be used. The whole punch must be replaced, which will affect the processing and production, waste time and affect production efficiency. . Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to propose a punch device that can exchange the punch head. [0004] The technical solution of the present invention is achieved as follows: a punch device, includ...
