Methods to prevent wavy edges in formed plates pressed by color Roll Forming Machine:

1. To avoid wavy edges of formed color steel plates, this should be considered and prevented in the early stages of design. When wavy edges appear, it should be noted that the width of the end edge cannot be too large. At the beginning of the design, you can refer to the ratio of the width of the end edge to the thickness of the sheet, and design according to the ratio of lead or less than 40. The bending angle can be assigned according to the formula. If waves appear during the pressing process, you can try to reduce or eliminate the wavy edges by appropriately adding the number of forming rows.

2. The edges can be reduced or eliminated by pre-bending, using a leveling machine, changing the frame spacing, supporting rollers, adjusting the roller gap, etc.

3. The rear forming row has a greater impact on the wavy edge. Under the same end face and roll forming configuration, thick plates are more prone to wavy bending than thin plates. In order to reduce or eliminate wave bending, the deformation should be considered at the beginning of the design, and the subsequent forming rows should not have excessive deformation.

4. Each row may produce wavy edges. The number of rows in the front has a greater impact on the appearance of wavy edges. Thinner boards are more likely to have wavy edges than thicker boards, and wide edges are more likely to appear than narrow edges. Wavy edges.
