Background

A stamping die is a special process equipment for processing materials (metal or nonmetal) into parts (or semi-finished products) in cold stamping. Stamping is a press working method in which a die mounted on a press is used to apply pressure to a material at room temperature to cause separation or plastic deformation thereof, thereby obtaining a desired part.

In the drawing process of stamping, generally, feeding is firstly carried out, blanking is carried out, and drawing and cutting are finally carried out. Therefore, a stamping die plate capable of integrating feeding, blanking, stretching and cutting is urgently needed to reduce the consumption of manpower and material resources and improve the production efficiency.

Patent CN108787901A discloses a stamping die of diversified location, including the stamping die body, stamping die's inside sliding connection has the mould to derive the mechanism down, the location top cap has been cup jointed to the one end of guide pin bushing, and the outside of guide pin bushing has cup jointed nitrogen gas spring, the one end threaded connection of hydraulic pressure pipe has the hydraulic pressure jar, one side of pushing mechanism is rotated and is connected with vibrating motor, vibrating motor's bottom is provided with the base, the bottom threaded connection of base has the backing plate. The positioning between the upper stamping die and the lower stamping die can be more accurate by combining the top block, the positioning cone groove, the partition plate, the positioning cone shell, the second spring and the bottom block; in the actual stamping process, the upper module is easy to shake left and right due to the vibration generated by the back-and-forth movement of the upper module, so that the upper module and the lower module of the device are still positioned in a deviation manner; and in the use process, because the cutting device is not contained, the device needs one more manual cutting.
