Improvement of forged gear blank production line

Some situations and solutions encountered in the forged gear blank production line are described below. (1) During parting, the forged gear blank can not always stay in the lower die, which is convenient for robot picking. This kind of press generally adopts hydraulic feeding and jacking structure, but the...
