A large number of cold stamping processes are used in continuous production, which is suitable for the mass production of A106B seamless pipes with multiple varieties in the automotive stamping industry. In medium and heavy duty vehicles, most of the covering parts such as body panels, as well as some load-bearing and supporting parts such as frames, carriages, and other automotive components are automotive stamping parts. The steel used for cold stamping mainly consists of steel plates and strips, accounting for 72.6% of the steel consumption of the entire vehicle. Cold stamping materials are closely related to the production of automotive stamping parts. The quality of materials not only determines the performance of the product, but also directly affects the process design of automotive stamping parts, affecting the quality, cost, service life, and production organization of the product. Therefore, selecting materials reasonably is an important and complex task.

When selecting materials, first select metal materials with different mechanical properties based on the type of automotive stamping and usage characteristics, in order to achieve the goal of ensuring product quality and saving materials.

The following principles should be followed when selecting automotive component materials:

The selected material should first meet the performance requirements of automotive components.

2. The selected material should have good process performance.

3. The selected materials should have good economy.

The local construction method for the body paint surface is:

Wash the car first and use solvent to clean the surface of the panel to be repaired and its surroundings; Then polish (to remove dirt and rust spots) with thin sand, and all surfaces to be repaired should be polished with 360-400 grit sandpaper.

After all polishing construction is completed, clean and repair the surface and its surroundings again, and protect adjacent areas with adhesive tape as needed; If necessary, apply a two component metal surface conditioner to the exposed metal surface. Then spray primer, apply putty and spray intermediate coating, and if necessary, perform moderate polishing; Spray sealing primer; Spray appropriate topcoat.
