Background The stamping device for automobile sheet metal parts is special equipment for plastic forming processing of metal sheet materials in the automobile manufacturing process so as to obtain automobile parts with required shapes and sizes. Such devices are one of the key process equipment in the manufacture of automotive bodies. When the sheet is subjected to stamping forming, the sheet is separated to generate fragments due to the huge pressure applied by the punch during stamping because of the low-hardness and high-ductility sheet metal such as aluminum plates and stainless iron, the fragments are easy to deform, the adhered fragments not only can cause passivation of the cutting edge of the punch and abnormal clearance of the die, aggravate die abrasion and shorten the service life of the die, but also can form defects on the surface of the pressed sheet metal in the subsequent stamping process, and the size precision and appearance quality of the stamped parts are affected. Especially in seasons with lower ambient temperature, the lubrication effect of the material surface is weakened, the cold welding effect is more obvious, the phenomenon of chip adhesion is further aggravated, and the influence on the stability of the stamping process and the qualification rate of products is more prominent. Meanwhile, oily substances such as rust-proof oil and the like can be smeared on the surface of the metal plate when the metal plate leaves the factory, and external impurities are easy to adhere to the metal plate in the transportation process due to overlarge viscosity, and can enter the die along with the movement of the metal plate, so that the metal plate can not only cause damage to the die, but also influence the forming effect. Although the blowing structure can be arranged at the punching feeding hole to blow off impurities, the impurities with strong adhesive capacity cannot be effectively removed.
