Do you know what are the installation procedures of automobile stamping parts?
If the installation process of automobile stamping parts is classified, stamping is generally divided into two major processes: forming and separation. Each process has its inspection standards. The goal of forming is to make the sheet into the desired shape and size without breaking the blank. The purpose of the separation process is to make the stamping parts separate from the sheet material according to the established target, and at the same time, it is necessary to ensure that the quality of the separation section meets the standard requirements.
Reasons for the loss of stamping dies
- (1) The material of the main working parts of the mold is improperly selected. The material has poor performance and is not wear-resistant; the die steel is not refined and has a large number of smelting defects; the convex and concave die, the forging process of the forging blank is not perfect, and there are hidden heat treatment risks.
- (2) The mold structure design problem, the die structure is unreasonable. The slender punch is not designed with a reinforcement device, the discharge port is not smooth, and the stacking occurs.
- (3) The molding process is not perfect, which is mainly manifested in the poor internal quality of the convex and concave die forging blanks, and the problems with the heat treatment technology and process, which cause the convex and concave dies to be hardened, soft spots and uneven hardness. Sometimes micro-cracks or even cracking occur, grinding and polishing are not in place, and the surface roughness value is too large.
- (4) Unlubricated or lubricated but ineffective. The surface treatment processes of automobile stamping parts are: gold plating, silver plating, nickel plating, and zinc plating.
