The pad 112 and the punch 113 are fixed together by fastening bolts 114. The pad 112 is detachable, and its thickness can be replaced according to the secondary bending or surface flatness dimensions of the U-shaped pre-bent section, which improves the flexibility and adaptability of the ultra-wide metal sheet bending and shaping device. If the secondary bending is still insufficient, the thickness of the pad 112 can be increased and replaced to quickly adjust the bending amount of the secondary bending. The stripping assembly 2 includes an upper pressure block 21 and a side push slider 22. The side push slider 22 has a second...
