Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment auxiliary tools, in particular to a special tooling for a punching device. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, tubes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. It is a very common processing method, and stamping production is mainly carried out through a punch press.

[0003] The existing stamping equipment has the following disadvantages during production: many existing punching machines without continuous feeding mechanisms need to manually place the stamping raw materials on the top of the lower die and then use the punching machine to perform stamping production. For some stamping parts with high precision requirements, the workpiece raw materials need to be accurately placed at the appropriate position on the top of the lower die. The existing stamping dies only have basic forming functions and lack the positioning function for the workpiece raw materials. For this reason, we propose a special tooling for stamping devices.
