s3: the moving stamping part (7) of the moving male die (2) is firstly contacted with a workpiece to be processed and is supported by the workpiece to be processed, the position of the moving male die (2) is fixed, the main male die (1) continues to move, the sliding block (6) of the moving male die (2) and the sliding groove (5) of the main male die (1) relatively slide, because one end, close to the main mounting part (3), of the sliding groove (5) is far away from the central line of the main male die (1), the moving male die (2) moves towards the direction far away from the central line of the main male die (1) in the process of approaching the main mounting part (3) of the main male die (1) until the moving limiting part (8) of the moving male die (2) is contacted with the supporting part (18) of the limiting plate (9), and the position of the moving male die (2) is fixed relative to the main male die (1);
s4: the main male die (1) and the movable male die (2) continue to move for punching, a workpiece to be machined on the female die (10) is punched and machined in a matched mode with the female die (10), and after machining is finished, the driving assembly drives the main male die (1) to be separated from the female die (10);
s5: the main body male die (1) is separated from the processed workpiece, and meanwhile, the main body male die and the moving male die (2) slide relatively, the moving male die (2) is close to the central line of the main body male die (1) in the sliding process until the moving male die (2) is also driven to be separated from the processed workpiece, and one-time stamping is completed.
