Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping equipment, in particular to an electric vehicle frame plate stamping equipment and a use method thereof. BACKGROUND

[0002] With the enhancement of environmental awareness and the progress of technology, the demand for electric vehicles is increasing. Electric vehicles have become an important part of future urban transportation due to their environmental protection and energy saving characteristics, especially in short-distance travel and urban commuting. Electric vehicles are favored by consumers due to their small size, easy operation, and flexible driving characteristics.

[0003] In the production and processing process of electric vehicles, most of the vehicle bodies are welded from several plates, and these plates will be subjected to stamping work by stamping equipment in the processing process. The stamping equipment is a commonly used component in mechanical processing. The stamping equipment includes a moving die and a fixed die. When stamping, the moving die is punched into the fixed die to stamp and form the plate. However, during the stamping and forming process of the deformed plate, friction occurs between the plate and the moving die and the fixed die, which produces some debris. Especially when the gap between the moving die and the fixed die is too small, the knife edges of the two moving dies and the fixed dies are squeezed and scratched, which produces a lot of debris. Excessive accumulation of these debris will affect the forming of the workpiece. At the same time, most stamping equipment uses hydraulic rods for stamping. The hydraulic rod is ejected for stamping. When the moving die and the fixed die come into contact, a collision occurs. The hydraulic rod is ejected and collides with the counterforce, which will apply an opposite force to the direction in which the hydraulic rod is extended, thereby causing pressure fluctuations in the hydraulic system. This will damage other components in the hydraulic system and affect the service life of the stamping equipment. In severe cases, the hydraulic rod will retract by a certain distance, causing the size and shape of the stamped part to deviate, affecting the quality and precision of the product. SUMMARY
