Sheet metal lower shell precision stamping forming device

Abstract

The utility model discloses a kind of sheet metal lower shell precision punch forming device, it is related to mechanical processing technical field, including fixed mechanism, the fixed mechanism includes stamping station, the top of the stamping station is fixedly connected with slide rail, the surface of the slide rail is slidably connected with sliding sleeve;Force mechanism, the force mechanism includes fixed frame, and the bottom of the fixed frame is fixedly connected with the top of stamping station.The utility model is provided with three groups of stamping head of stamping depth increasing by stage stamping mechanism, cooperate spring and second guide rod, make sheet metal material uniform deformation in gradually stressed process, effectively avoid the crack, fold and other defects produced by single stamping pressure concentration, simultaneously, stress can be dispersed by stage stamping, reduce material local excessive deformation, especially suitable for different material sheet metal part processing, improve process adaptability.
