Progressive lamination dies are a multi-station die used to continuously complete multiple processes of stamping parts processing on the same press. It consists of multiple independent stamping dies, each of which is responsible for completing a process, and the dies are arranged on the die frame of the press in the order of the processes. The workpiece is transferred one by one between the dies, and the processing is completed one by one.Progressive lamination dies are widely used and are mainly used in:1. Automotive industry: used to manufacture auto body parts, such as doors, roofs, fenders, etc. Since auto body parts are usually composed of multiple stamping parts, and have high requirements for accuracy and consistency, progressive lamination dies can be used to continuously complete the processing of these stamping parts2.

After years of development, the design level, processing and manufacturing technology, mold, and another equipment level of the stator and rotor iron core of electric machines in China have been greatly improved. With the introduction of manufacturing technology from advanced countries in the world and the rapid development of professional manufacturing enterprises for stator and rotor iron cores in China, the production technology maturity of motor iron cores in China has also been continuously improved. Among them, the stamping process and press mounting process technology have been relatively mature, and a certain amount of technical experience has also been accumulated in the research, testing technology, special mold design, and manufacturing of basic materials such as silicon steel sheets. At present, there are a large number of enterprises in the motor iron core manufacturing industry in China, and the scale of enterprises is relatively small. Therefore, the overall level of using high-precision, high-efficiency, and long-life multi-station progressive molds and automated stamping equipment is not high. In recent years, as downstream customers have increasingly higher requirements for the accuracy of motor iron cores and intensified market competition, large-scale enterprises in the industry have also developed towards high accuracy, high production efficiency, high stability, and low energy consumption and consumables in mass production, which has greatly improved the level of molds, automatic or semi-automatic lamination tooling.
