Description

A precision hard alloy punch

technical field

The utility model relates to a punch, in particular to a precision hard alloy punch.

Background technique

The punching needle is an indispensable accessory when the stamping die is working. It is a replaceable die consumable. It is installed on the stamping die for continuous punching, stamping and punching operations, so that the processed material is separated or plastically deformed, so as to obtain the required For the finished or semi-finished products, most of the traditional punches are of the same shape. If you want to use other shapes of punches, you need to make another one, which will cause waste of materials, and they are still carried separately and are easy to lose. Therefore, for It is very necessary to design a precision carbide punch for the above problems.
