Description

A Stamping Die for Metal Processing with Good Stability

technical field

The invention relates to the technical field of metal processing, in particular to a stamping die for metal processing with good stability.

Background technique

Stamping is a forming processing method that applies external force to plates, strips, pipes and profiles by presses and molds to cause plastic deformation or separation to obtain workpieces (stamping parts) of required shape and size. Compared with castings and forgings, stamping parts have the characteristics of thinness, uniformity, lightness and strength.

During the stamping process of the metal plate, it is necessary to place the metal plate above the stamping seat, wait for the stamping head to move towards the metal plate, and stamp until it contacts the metal plate, but each time the metal plate is placed on the stamping seat It is inconvenient to locate the metal plate at the time, and the metal plate is prone to tilt, and there is a slight difference in the position of each stamping. At the same time, in the process of pressing the stamping head and the metal plate base, the metal plate is likely to move, which in turn affects the stamping effect. , so we propose a stamping die for metal processing with good stability.
