The mechanical arm assembly is used to drive the mounting arm and the movable end seat to move. The positioning seat is installed on the movable end seat. The invention sets a mechanical arm assembly, a positioning seat, a stacking assembly and a blanking assembly. After the processing is completed, the mechanical arm assembly, the stacking assembly and the blanking assembly are used to place the workpiece on the column, thereby realizing automatic unloading and stacking, with a high degree of automation. By setting two sets of positioning end covers, the next workpiece can be loaded while unloading, which effectively improves the production efficiency. At the same time, the workpiece is fixed by the blanking assembly to ensure the stability of the workpiece during processing, avoid the floating of the workpiece, and thus improve the stamping quality.

[0003] When using the positioning slot block to position the original sheet during the stamping and forming production process of the motor stator and rotor punching sheets, the positioning slot block is usually first installed on the stamping machine through the base, and then the stamping die is inserted into the internal circular groove of the positioning slot block. Finally, during stamping, the original sheet only needs to be placed in the inner wall of the positioning slot block to perform stamping and forming processing on the original sheet. Since the inner wall size of the traditional positioning slot block is fixed, and the original sheet sizes of the stator and rotor punching sheets that need to be stamped are different, the traditional positioning slot block can only position the stator and rotor punching original sheet of one size, resulting in low practicality of the positioning slot block and inconvenience in use.
