Description

A hot stamping die for cylindrical nut processing

technical field

Background technique

Dies are widely used in blanking, extrusion, die casting and forming of plastics and rubber. It is a tool that forms a blank with a specific shape and size under the action of an external force. Most of the products used in daily life and industrial production are produced by mould technology.

Stamping die is a special process equipment for processing materials into parts in cold stamping processing, called cold stamping die. Cold stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. Using this method to process nuts has a better processing effect. poor, and the processing efficiency is low, and cracks on the surface of the nut are prone to occur, resulting in an increase in the defective rate.

After retrieval, the existing patent (publication number: CN2030514U) discloses a die for cold extrusion forming a hub nut, which has an oil cylinder above the punch, and the piston in it is pressed against the upper top surface of the punch through the intermediate rod. When the punch is working, the oil cylinder is filled with oil and the reversing valve is closed. When the punch enters the blank of the workpiece to make the hole depth meet the requirements, the punch is quickly unloaded and is in a floating state. Although the patented technology simplifies the process flow, and can process fully qualified products at one time, the extrusion force is more than 40% lower than the extrusion force of secondary molding, but there is an unreasonable mold structure and high requirements for the performance of the mold. problems, resulting in low die usage rate, high rejection rate of forged and stamped nut blanks, and increased production costs.
