Concave die case for stamping die

Abstract

The invention discloses a die cover for a stamping die, which comprises a die cover body, a detent pin hole, a die hole, a die end face, an arc groove, a sealing cover, a vent hole, a vent, and a hollow bearing ring Cavity, side wall, material escape part, material jam part, cutting edge part, punching punch, bolt hole, pin hole, waste material, insulation room, knife tooth and positioning column, and the outer side of the end face of the die is provided with a detent pin hole, The top of the positioning column is provided with a sealing cover, the inside of the die sleeve body is provided with a die hole, the outside of the side wall is provided with an air vent, and the bottom of the die hole is provided with a punching punch. The invention makes it easier to maintain and replace the die sleeve. It is convenient and effectively improves the life of the die, and reduces the proportion of defective products in stamping products. The designed die set for stamping dies has good heat dissipation effect, thermal fatigue resistance, good oxidation resistance and thermal stability. Sex, simple structure, low cost and wide applicability.

Description

technical field [0001] The invention relates to a die cover, in particular to a die cover for a stamping die. Background technique [0002] A large part of the production process of the mold is the process of repeated rectification. Each rectification requires the technical department to come up with a plan, and the fitter assembles or repairs the welding. The process is complicated and involves many departments, which is time-consuming and labor-intensive. Insufficient, so that the plate can only be punched in different processes, which not only increases the punching process, wastes manpower, financial and material resources, but also slows down the speed of the finished product. At the same time, the service life of the hot forging die has always been a key factor affecting this type of product , the previous die is limited by its structure, and its service life has not been able to meet an ideal requirement, so that the user's production cost cannot be effectively contro...

[0002] A large part of the production process of the mold is the process of repeated rectification. Each rectification requires the technical department to come up with a plan, and the fitter assembles or repairs the welding. The process is complicated and involves many departments, which is time-consuming and labor-intensive. Insufficient, so that the plate can only be punched in different processes, which not only increases the punching process, wastes manpower, financial and material resources, but also slows down the speed of the finished product. At the same time, the service life of the hot forging die has always been a key factor affecting this type of product , the previous die was limited by its structure, and its service life has not been able to meet an ideal requirement, so that the user's production cost cannot be effectively controlled, and it has also brought a lot of inconvenience to the use of stamping dies
