Abstract
The utility model provides a pumping pipe punch relating to the punch of a stamping die, which comprises a punch body. The bottom of the punch body is successively indented and equipped with an inner stamping portion and an outer stamping portion. The connection part of the inner stamping portion and the outer stamping portion is equipped with a shoulder. Due to the adoption of the pumping pipe punch, a stamping workpiece can be timely returned after being stamped due to the arrangement of the shoulder arranged between the inner stamping portion and the outer stamping portion. Therefore, the stamping workpiece is prevented from being clamped by the inner stamping portion and the outer stamping portion, thus is not damaged.
Description
Technical field
The utility model relates to a kind of drift of diel.
Background technology
It is the critical process in some metal product punching courses that pipe is taken out in punching press; It is with diel the semi-finished product extrustion of metals to be realized; In order to guarantee to take out the requirement of pipe metalwork edge definition; The pipe drift of taking out that mould is installed has proposed very high requirement, avoids that fastener causes metalwork to take out the tube edges damage after the punching press.
Summary of the invention
The utility model is just in order to address the above problem, and a kind of pipe drift of taking out is provided, and it can realize that extrustion of metals retreats part, the damage of avoiding the drift fastener to cause.
In order to achieve the above object, the technical scheme of the utility model employing is:
A kind of pipe drift of taking out, the drift body is characterized in that: said drift body bottom indentation successively is provided with interior pressing part and outer pressing part, and said interior pressing part is provided with shoulder with outer pressing part connecting portion.
The above drift bodies top is provided with screw.
The beneficial effect of the utility model is, owing between interior pressing part and outer pressing part, be provided with shoulder, in time moves back part after making the stamping parts punching press, on pressing part and the outer pressing part, also avoided the damage that stamping parts is caused in avoiding being stuck in.
