Cnc Stamping Parts

Common defects and treatment methods of cnc stamping parts:
The competition in the current automobile market is intensifying. When consumers choose a product, they are not limited to an appropriate price, but also pay more attention to the quality and quality of the car. Stamping is the first of the four major automobile processes. The quality problems of stamping parts not only affect the appearance of the car body, but also reduce the corrosion resistance and service life of the parts. Therefore, the quality defect control of stamping parts is very important.

Common quality problems in the forming process of stamping parts mainly include defects such as wrinkling, cracking, springback, and surface quality (collapse, slip, impact). The above problems account for more than 85% of the quality rectification of stamping parts. Repeated rectification and maintenance of molds lead to a reduction in service life, a sharp increase in downtime, and increased production costs due to rework or even scrapping of products. Therefore, the generation and solution of key defects in stamping parts are discussed. It has important practical value for improving the forming quality and production efficiency of products.

wrinkling and lapping
Defect description: Due to the large difference between the size of the thickness direction of the sheet and the size of the plane direction, the thickness direction is unstable. When the stress in the plane direction reaches a certain level, the thickness direction is unstable, resulting in wrinkling
