(5) Then, placing a workpiece III to be machined on the die holder on the front side, driving the die holder on the front side to move backwards by the electric cylinder on the front side, moving the die holder on the front side to be right below the module fixing piece, driving the rotating shaft to rotate through the servo motor, and driving the module fixing piece to rotate by the rotating shaft so that a stamping module III used for machining the workpiece III on the module fixing piece corresponds to the die holder on the front side;
(6) The power source drives the two wall plates to move downwards, the stripper plate is pressed to move upwards after being contacted with the third workpiece, and the die head of the third stamping module punches the third workpiece after penetrating through the through hole in the stripper plate; after the punching operation is finished, the power source drives the two wall plates to move upwards, the elastic component pushes the stripper plate to reset, and the stripper plate enables the workpiece III to be separated from the die head of the punching module III; the electric cylinder positioned on the front side drives the die holder on the front side to move forwards, so that the die holder on the front side is moved out from the position right below the module fixing piece;
(7) Finally, placing a workpiece IV to be machined on the die holder at the rear side, driving the die holder at the rear side to move forwards by the electric cylinder at the rear side, moving the die holder at the rear side to be right below the module fixing piece, driving the rotating shaft to rotate by the servo motor, and driving the module fixing piece to rotate by the rotating shaft so that the stamping module IV used for machining the workpiece IV on the module fixing piece corresponds to the die holder at the rear side;
(8) The power source drives the two wall plates to move downwards, the stripper plate is pressed to move upwards after being contacted with the fourth workpiece, and the die head of the fourth stamping module performs stamping operation on the fourth workpiece after penetrating through the through hole in the stripper plate; after the punching operation is finished, the power source drives the two wall plates to move upwards, the elastic component pushes the stripper plate to reset, and the stripper plate enables the workpiece IV to be separated from the die head of the punching module IV; the electric cylinder positioned at the rear side drives the die holder at the rear side to move backwards, so that the die holder at the rear side is moved out from the position right below the module fixing piece; and completing the one-time stamping operation process.
2. The stamping method for producing automobile parts as claimed in claim 1, wherein the right electric cylinder, the left electric cylinder, the front electric cylinder and the rear electric cylinder are controlled by a PLC controller to work in turn.
