Abstract
Description
Technical Field

[0002] A punching press is a pressure processing equipment that applies external force to plates, strips, pipes, profiles, etc. through a mold, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) with the required shape and size. When processing soft sheet workpieces, the punching press can utilize its powerful pressure and combine with the design of the mold to perform processing operations such as punching, trimming, stretching, and bending on the soft sheet workpieces, thereby obtaining the required stamped parts.
[0003] When the existing punching press processes soft sheet workpieces, when the thickness of the soft sheet workpieces is inconsistent, it is difficult to flatten them during feeding, which may lead to uneven material flow during the stamping process, resulting in dimensional deviation and shape distortion of the stamped parts. Moreover, when the punching press feeds materials, it does not have the function of actively flattening the workpieces itself. It mainly realizes stamping processing by applying pressure to the workpieces through the mold. Therefore, if workpieces with different thicknesses are not fully flattened before entering the stamping area, unevenness may occur during the stamping process. Summary of the Utility Model
