For stamping, the singlestation single die structure, low productivity, and sheet metal parts can not be too plicated, or need more singlestation dies vice can be achieved. If the use of progressive die stamping production, you can change these shortings. Multiposition progressive die progressive die in general developed on the basis of a high precision, high efficiency, long life of the mold, the mold is an important representative of technologyintensive, is one of the development die. The punching die blanking addition to the work, but also the characteristics of part structure based on the nature and shape, plete beading, punching hole, bending, deep drawing forming process can even be pleted in the mold assembly process. Stamping, it will be with the material or strip materials sent from the mold after the entrance, step in the strictly controlled conditions, accuracy, forming process in accordance with the order arranged by the continuous pressing of the station, at the last station, or by punching cut off, the system can be washed to meet the requirements of stamping products. To ensure multiposition progressive die work, die must have a highprecisionoriented and accurate fixed pitch system, equipped with automatic feeding, automatic parts, safety testing and other devices is characterized by progressive die for high production efficie
