[0003] However, the above-mentioned existing stamping device for automobile parts processing places the part to be stamped on the lower stamping die, starts the hydraulic cylinder to move the connecting plate downward, and the sliding sleeve slides downward on the support rod. When the clamping block contacts the upper surface of the part, it continues to press downward, squeezing the first spring until the ejection block contacts the bottom of the limit groove, and continues to squeeze downward. The clamping block squeezes the third spring, and the connecting rod squeezes the second spring upward until the upper stamping die stamps the part. After the stamping is completed, the hydraulic cylinder moves upward with the connecting plate, and the first spring squeezes the ejection block upward to drive the part to rise, making it convenient for workers to take out the parts. The size of the lower stamping die in the device is determined, and it can only limit automobile parts of the same size, and it is difficult to limit automobile parts of multiple different sizes, resulting in a relatively single practicality.
