Description

Technical Field

[0001] The utility model relates to the technical field of mechanical parts processing, in particular to a punching device for parts processing. Background Art

[0002] Stamping is a forming method that relies on a press and a die to apply external force to plates, strips, pipes, and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size. In the stamping process of some mechanical parts today, the parts need to be placed on a stamping table and deformed by stamping. However, after the stamping is completed, the parts are easily stuck inside the stamping die, making it difficult to take them out. In addition, since the stamping die is in a groove shape as a whole, impurities are easily introduced into it, causing the impurities to adhere to the mechanical parts during stamping, and after being squeezed by the stamping head, the mechanical parts are easily damaged. In addition, when a traditional stamping device is used to stamp mechanical parts, due to the high pressure in the middle, the two ends of the mechanical parts are easily lifted up, affecting the stamping effect. The utility model proposes a new solution to the above problems. Utility Model Content
