AI Technical Summary

Technical Problem

In the existing technology, there is a problem of lubrication supply and demand mismatch in the cold stamping production of automotive parts. This leads to insufficient oil supply when the frictional resistance is at its maximum, resulting in mold wear and forming defects. At the end of mold closing, the accumulation of lubricating oil causes the back pressure to rise, which affects the quality of the parts.

Method used

The oil spraying and suction mechanism adopts a mechanical structure, which utilizes the kinetic energy storage and potential energy release of the upper mold base to spray lubricating medium at the initial stage of mold closing and suck away excess medium at the end of mold closing. Combined with the air injection mechanism to assist in demolding, it achieves precise control of the lubricating medium.

Benefits of technology

It effectively solves the problem of lubrication supply and demand mismatch, reduces mold wear and forming defects, ensures the surface quality of the parts, is energy-saving and environmentally friendly, and is compatible with existing stamping equipment.
