technical field

The invention relates to the technical field of stamping, in particular to a stamping forming die for automobile parts.

Background technique

Most of the covers on automobiles are made of steel plates, which are called automobile plates. The main processing method of automobile plates is to use stamping dies to stamp and form steel plates, so as to use the cheapest method for mass production. Stamping dies use The die installed on the press exerts pressure on the material to cause separation or plastic deformation. In industrial production, with the improvement of the quality requirements of the metal sheet, it is necessary to stamp and shape the metal sheet through a stamping die. At present, in the process of stamping and forming, the position of the mold is prone to deviation during pressing, and the vibration generated when the device is working will also cause the displacement of the plate, resulting in an error in the stamping of the plate, and the plate needs to be manually placed on the mold during the stamping process. Inconvenient to use.
