After the metal sheet is bent, The output shaft of the second hydraulic push rod 21 contracts to move the pressing module 25 out from the inner wall of the folding template 5. At this time, the first piston plate 10 is pushed to move by the output shaft of the first hydraulic push rod 9. The first piston plate 10 squeezes the hydraulic oil in the hydraulic cylinder 12, so that the second piston plate 14 provided in the first lifting sleeve 13 rises, and the lifting column 15 is driven to move upward by the second piston plate 14. The lifting column 15 drives the pushing module 19 to move upward through the second lifting sleeve 17.

After the pushing module 19 pushes the metal sheet in the folding template 5, the output shaft of the hydraulic cylinder 12 contracts, and the pushing module 19 is moved back to the inner wall of the circular module opening 7 again.
