Technical Field

Currently, wall panels are generally like... Figure 1 As shown, a left bend 2' is formed by bending the left side of the metal plate 1'. The left bend 2' includes an insert 21' and a left upright plate 22' connecting the insert 21' to the metal plate 1'. A right bend 3' is formed by bending the right side of the metal plate 1'. The right bend 3' includes an insert groove 31' and a right upright plate 32' connecting the insert groove 31' to the metal plate 1'.

Based on the shortcomings of existing roll forming production lines, there is an urgent need to design a production line with adjustable forming width and forming height to meet production needs.
