Abstract
The utility model relates to an ejector pin punch which comprises a punch body, an ejector pin and a pressure spring. The ejector pin punch is characterized in that a hole and a small hole are formed in the punch body. An ejector rod and a guide rod are arranged on the ejector pin. The inner guide rod and the pressure spring are arranged in the hole. The ejector rod is arranged in the small hole. A cavity is formed in the front end of the punch. Therefore, the punch body is hollow and the ejector pin is arranged in the punch body to help a screw be formed, so that a part is not prone to disengagement. The ejector pin punch is simple in structure and low in cost. The part is not prone to disengagement when processed. When the part is taken, the part is not prone to being adhered. In addition, the ejector pin punch is reliable in machining and high in production efficiency and quality.
Description
Technical field
The utility model relates to a kind of stamping cutting die, especially a kind of drift of thimble for the punching press screw.
Background technology
At present, on market, most of drifts are all solid, and this solid drift is easy sizing in punching course, thereby affect quality and the efficiency of product,, easily to the machine injury, impact for part processing.
Summary of the invention
The purpose of this utility model is to provide a kind of adding to be difficult for sizing man-hour for the deficiency that solves above-mentioned technology, can help the thimble drift of liftout.
In order to achieve the above object, a kind of thimble drift that the utility model is designed, it comprises punch body, thimble and stage clip, it is characterized in that in described punch body being provided with hole and aperture, be provided with push rod and guide post on thimble, interior guide post and stage clip are placed in hole, are provided with push rod in aperture, and the drift front end is provided with the shape chamber.Like this punch body is designed to hollowly, and is provided with thimble helps the screw moulding in punch body, make part be not easy to take off material.
In order to make the part after moulding be not easy to stick, it is characterized in that an end of described stage clip is connected with the rear end of guide post, after punching press finished, stage clip compacted when part breaks away from can provide restoring force, so that take off part like this.
A kind of thimble drift that the utility model obtains, simple in structure, cost is low, and part is difficult for taking off material man-hour adding, and be not easy again during pickup to stick, and processing is reliable, and production efficiency and quality are all higher.
