in the initial state, the pressing bar supporting frame 15 and the two pressing bars 17 on the pressing bar supporting frame are both positioned at the initial position, after the control system detects that the vehicle door moves in place, the pressing bar supporting frame 15 is lifted from the position a to the position b (step 1),
then the cylinder 18 is driven to act, the pressing bar supporting frame 15 is driven to horizontally move from the position b to the workpiece direction to a pre-pressing preparation position c (step 2),
after the control system receives a signal that the pressing bar support frame 15 moves in place (realized by a sensor arranged at a blank pressing station in advance), the servo motor 5 works to drive the pressing bar support frame 15 to move downwards, and the pressing bar support frame 15 moves to a pre-pressing completion position d from the position c, and in the process, the pressing bar 17 relatively arranged below the pressing bar support frame 15 is directly pressed on a workpiece to complete a pre-pressing process (step 3);
