The output end of the first hydraulic push rod 5 passes through the L-shaped plate 3 and is fixedly connected to a positioning plate 8. A bending head 9 is arranged at the bottom of the positioning plate 8, and the bending head 9 matches the bending seat 4. The output end of the second hydraulic push rod 6 passes through the L-shaped plate 3 and is fixedly connected to a traction rope 10. The traction rope 10 is a steel twisted rope. By using the set steel twisted rope, the structural strength of the traction rope 10 can be effectively guaranteed, thereby ensuring the service life of the steel twisted rope.

[0031] The side wall of the L-shaped plate 3 is rotatably provided with a reciprocating screw 11, and the rod wall of the reciprocating screw 11 is rotatably sleeved with a winding wheel 12, the traction rope 10 matches the winding wheel 12, and the side wall of the winding wheel 12 is provided with a driving mechanism, which is transmission-connected to the reciprocating screw 11, and the rod wall of the reciprocating screw 11 is threadedly sleeved with a slider 13, and the side wall of the slider 13 is fixedly provided with an L-shaped push rod 14, which matches the bending seat 4. By utilizing the threaded sleeve of the reciprocating screw 11 and the slider 13, the slider 13 can be driven to drive the L-shaped push rod 14 to move during the rotation of the reciprocating screw 11, thereby pushing out the formed sheet metal parts, effectively reducing the work intensity of the staff and improving the work efficiency.

[0032] like Figure 2-3 As shown, the driving mechanism includes a sleeve 15, a disc 16 and a driving rod 17. Two first L-shaped rods 18 are symmetrically fixedly arranged on the side wall of the winding wheel 12.
