The conclusion of the application of beryllium copper alloy in automobile die The stamping operation of automobile panel is one of the four major processes of vehicle manufacturing, and it is the primary link in body manufacturing. The quality level of stamping parts lays the foundation for the quality of the body. Beryllium-copper alloy materials are widely used in the problem of strain or excessive wear between the mold and the workpiece or between the workpiece and the workpiece due to various types of wear.
Stamping parts are stamped and formed by stamping dies. During the forming process of stretching (drawing, stretching), bending, flanging, etc., the problem of strain on the surface of the workpiece is easy to occur. Automobile beam parts are often made of thicker steel plates. In addition, for the sake of safety and energy saving, more and more high-strength (high-tensile) steel plates are used in automobile parts. The molds are subjected to extremely high forming stress, and the problem of surface strain on the workpiece is even more serious. Workpiece quality. If the surface is damaged, the surface of the mold will also be damaged. If the production continues at this time, on the one hand, the surface quality of the workpiece will be further deteriorated, and on the other hand, the workpiece may be pulled and cracked. The solution to the problem is usually to stop grinding and polishing the surface of the mold, so that the repeated grinding will change the size of the mold.
Beryllium copper alloy is currently one of the best solutions to solve the problem of beam parts. The problem of workpiece size due to wear and other problems, after using beryllium copper alloy material, reduces the frequency of mold polishing and increases the service life by ten times. Normal. The problem of workpiece strain is the result of adhesive wear. There are many ways to solve the problem of workpiece strain, which should be selected according to the situation. Under normal circumstances, the use of TD cladding treatment and the use of beryllium copper alloy materials are the most effective and economical methods to solve the problem of surface strain on the workpiece and the convex and concave molds.
