Description

Technical Field

[0001] The utility model relates to the technical field of part stamping, in particular to a part stamping and forming device. Background Technique

[0002] In the automotive parts manufacturing industry, stamping and forming technology is widely used due to its characteristics of high efficiency and mass production. However, during the stamping and forming process, the friction problem between the die and the workpiece has always been a difficult problem to be solved urgently. The friction between the die and the workpiece will not only lead to unstable stamping quality, such as defects like scratches and unevenness on the surface of the part, but also increase the wear of the die, shorten the service life of the die, and increase production costs.

[0003] During the stamping of automotive parts by traditional stamping and forming devices, there are often no effective lubrication measures, which cannot effectively reduce the friction between the die and the part, resulting in serious die wear. Some enterprises use the method of manually applying lubricating oil, but this method is inefficient and it is difficult to ensure the uniformity of application. Therefore, we propose a part stamping and forming device. Content of the Utility Model
