First of all, the designed automotive stamping parts must be conducive to improving the utilization rate of metal materials, reducing the variety and specifications of materials, and reducing the consumption of materials as much as possible. If allowed, stamping parts can be made of low-cost materials, and the parts can be punched with no waste and less waste as much as possible.

Secondly, the designed automotive stamping parts must have a simple shape and a reasonable structure, which is conducive to simplifying the mold structure and the number of processes, so that the processing of the entire part can be completed with few and simple stamping processes, reducing the need for processing by other methods, and is conducive to Stamping operation is convenient for organizing mechanized and automated production to improve labor productivity.

Of course, the designed automotive stampings must also meet product use and technical performance, and be easy to assemble and repair. At the same time, it is beneficial to use the existing equipment, process equipment and process flow to process it as much as possible, and it is beneficial to prolong the service life of the die.

In addition, the designed stamping parts should try to make the dimensional accuracy level and surface roughness level as low as possible under the condition of ensuring normal use, which is conducive to product interchange, reducing waste, ensuring stable product quality, and reducing other cost, increased value.

Introduction of automotive stamping parts What are the reasons for the coiling of stamping parts in the general production process?

1. The edge of the material has irregular damage, and the material exceeds the qualified quality standard.

2. Due to the sliding of the stick, when a foreign object falls into it, a bubble-shaped bulge is formed on the back of the coil

3. There are foreign objects outside the material mixed in on the surface or inside of the steel. When the foreign objects are peeled off, the coil material is like a scar that has been exposed, which is horrible.

4. When there is a stick mark caused by foreign matter sticking to the stick, the surface depth caused by the foreign matter will produce obvious marks.

5. For scratches caused by the surface of the stick or foreign matter, the corners will generally be wrinkled or deformed due to uneven stress, which will lead to damage to the corners of the coil.
