Abstract：

The principle and key techniques of automatic laminating, process of automatic lamination for rotor core were introduced. Taking a motor rotor as an example, the structure characteristics and stamping forming process of motor rotor were analyzed. According to the production requirements，motor rotor core was produced by automatic laminating technology with progressive die. By comparing the four kinds of layouts, the scheme with the highest rate of material utilization was selected,and progressive die station was designed. Then, stamping process such as blanking force, pressure center, mould process size etc. were calculated. The structure of the main die parts and the overall structure of the mold were designed,and the mold assembly was drawed. Results show that the processes of flush laminating point, blanking, laminating for lamination of rotor core formed by a set of automatic laminating progressive die are conducted continuously, which realizes the high precision and high efficiency production.
