Automobile Industry

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:
1.The chosen materials must first meet the performance requirements of auto parts;
2.The chosen materials must have good process performance;

A. Multiple large and heavy-duty mechanical presses equipped with automated transfers form an automated flexible press line

These machines adopt an advanced multi-link transmission system on the structure. The multi-link mechanisms that drive the inner and outer sliders are optimally designed by the computer, so that the operation of the four groups of rods is optimally synchronized, and the inner slider has a higher degree travel and return speed in one stroke, low and uniform work stroke. This feature can effectively improve the accuracy of parts and die life, reduce scrap rate. The automatic stamping production line composed of them has large tonnage, large stroke, large worktable, large tonnage air cushions, automatic loading and unloading transfer system, automatic die change system, and a full-featured touch screen monitoring system. Whole production line is with high production speed and high precision.

B. Production of large multi-station presses

The machine adopts many international advanced technologies such as electronically controlled synchronization, electronic servo three-coordinate feeding, multiple connecting rods, automatic die changing, mold protection and has various automatic functions such as remote diagnosis, remote control and network communication, suitable for cold stamping processes such as drawing, bending, blanking and forming of sheet metal parts in automobile manufacturing.
