Novel progressive die

Abstract

The invention discloses a novel progressive die, and relates to a stamping die. The novel progressive die comprises an upper die holder, a lower die holder and a die handle. A female die is arranged on the upper surface of the lower die holder, a feed male die is arranged on the lower surface of the upper die holder, a feed female die hole is formed in the position, corresponding to the feed male die, of the female die, a stripper plate is connected to the feed male die in a sleeved mode, the stripper plate is movably connected with the upper die holder through a stripper bolt, a discharge rubber blanket is connected to the stripper bolt in a sleeved mode, a lower base plate is arranged at the position, close to the feed male die, of the lower surface of the upper die holder, a punching male die is arranged on the lower surface of the lower base plate, and a punching female die hole is formed in the position, corresponding to the punching male die, of the female die. Punching and feeding of workpieces can be successively completed in a die, production efficiency is improved, repeated positioning of the workpieces is avoided, and product accuracy is improved. The punching male die can not be easily broken, the service life is long, the die manufacturing process is simple, and die cost is reduced.

Description

technical field [0001] The invention relates to a stamping die, in particular to a novel progressive die. Background technique [0002] Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to a material at room temperature to cause separation or plastic deformation to obtain the required parts. Stamping die is an essential process equipment for stamping production, and it is a technology-intensive product, which can perform forming processes such as punching, blanking, bending and deep drawing. The quality, production efficiency and production cost of stamping parts are directly related to the design and manufacture of molds. In the stamping process, it is often necessary to punch holes on the blanked workpiece. To use the existing mold, the workpiece needs to be blanked in the blanking die first, and then put into the punching die to punch holes. This has many procedures and low production efficiency. And the workpiece needs to ...

AI Technical Summary

Problems solved by technology

In the stamping process, it is often necessary to punch holes on the blanked workpiece. To use the existing mold, the workpiece needs to be blanked in the blanking die first, and then put into the punching die to punch holes. This has many procedures and low production efficiency. And the workpiece needs to be positioned repeatedly, which affects the accuracy and quality of the product

In addition, the hole punched on the blanking part is generally a small hole with a small diameter. When forming a small hole, the corresponding punch is a slender rod with poor strength and rigidity. The punch is prone to bending deformation during punching. And broken, when the material to be punched is thicker, the punch is more likely to break, and the punch must be frequently shut down to replace the punch, which reduces the work efficiency and increases the cost of the mold
