Solution for Automobile Industry
Automobile stamping refers to the metal stamping of automobile parts. Some automobile stamping parts become auto parts directly after stamping, while others must be processed by welding, machining, or painting before becoming auto parts after stamping.
Stamping, welding, painting, and assembly are the four major processes in vehicle production. The number of stamping parts of sheet metal parts is more than 40% of the more than 2,000 auto parts in industry statistics, and the status of stamping processing equipment in the automotive industry is critical.
Today, the individual characteristics of automobiles accelerate the rate of model replacement. The model change is primarily reflected in the change of the body shape and structure, which is suitable for the ever-changing variety of sheet metal stamping parts.
In the production of automobile stamping parts, a large number of cold stamping processes are used, which is suitable for the needs of multi-variety and mass production of automobile stamping parts. Most covering parts, such as body outer panels, and some load-bearing and supporting parts, such as frame, carriage, and other auto parts, are auto stamping parts in medium and heavy-duty vehicles. Cold stamping steel is primarily steel plate and steel strip, accounting for 72.6 percent of total vehicle steel consumption.
Cold stamping materials have a close relationship with the production of automobile stamping parts. The quality of the material not only determines the performance of the product but also has a direct impact on The process design of the automotive stamping process affects the quality, cost, service life, and production organization of the product, so rational material selection is a critical and complex task.
When selecting materials, metal materials with different mechanical properties are chosen first, based on the type of automobile stamping and the characteristics of use, with the goal of not only ensuring product quality, but also saving materials.
The principles are as follows:
- The chosen materials must first meet the performance requirements of auto parts.
- The chosen materials must have good process performance.
