Place the elevator door panel to be processed on the conveying roller 3, push the elevator door panel to abut against the baffle 7, and then start the motor 12. The motor 12 drives the bidirectional screw 18 to rotate. The rotation of the bidirectional screw 18 drives the paired thread sleeves 17 to move towards each other. The movement of the thread sleeves 17 drives the connecting rod 16 to move towards each other along the through groove on the extension table 2, thereby driving a pair of limit blocks 11 to move towards each other, realizing the centering adjustment of the position of the elevator door panel and at the same time realizing the limitation of the elevator door panel.

[0025] Working principle:

[0026] During use, place the elevator door panel to be processed on the conveying roller 3, push the elevator door panel to abut against the baffle 7, and then start the motor 12. The motor 12 drives the bidirectional screw 18 to rotate. The rotation of the bidirectional screw 18 drives the paired thread sleeves 17 to move towards each other. The movement of the thread sleeves 17 drives the connecting rod 16 to move towards each other along the through groove on the extension table 2, thereby driving a pair of limit blocks 11 to move towards each other, realizing the centering adjustment of the position of the elevator door panel and at the same time realizing the limitation of the elevator door panel. Start the first hydraulic cylinder 5 to push the pressing plate 8 downward to realize the pressing of the elevator door panel. Starting the electric push rod 14 can drive the bearing plate 15 to rotate, thereby adjusting the bending angle of the elevator door panel. Finally, start the second hydraulic cylinder 6 to push the bending roller 9 downward to realize the bending treatment of the elevator door panel.
