Abstract:According to the operating characteristics of the open type double column inclinable punch, the system analysis was carried out, a kind of automatic feeding device was studied and developed. The device consisted of feeder mechanism, composite driving mechanism, mechanical arm and control system. In the course of feeder system operation, mechanical arm and feeding mechanisms were coordinated. Mechanical arm can accurately sent 03 mm thick silicon steel sheet to the position of press mold by vacuum chuck, and can adjust its speed. The successful operation of the device can effectively avoid accidental work injury, and significantly improve the production benefit.
