What is the reason why the plate rolled by the three-roll plate bending machine is not round?

Please choose to ensure that the welded joint is not round (whether the coil is round and apple-shaped).

Anshan Dazhengxin is a professional plate bending machine manufacturer in Northeast China.

If this is the case, then you need to deal with straight edges.

Two methods: 1. If it is a thin plate, bend the straight edge to the inside of the circle in advance (the curvature should exceed the arc of the circle you want to roll); In this way, there can be no straight edges when rolling.

2. For the thick plate, it is necessary to make a U-shaped arc striking plate in advance, and roll the straight edge with the arc striking plate colleagues in advance before rolling the plate to achieve the purpose of bending the straight edge.

3. The stupidest way is to increase the blanking length, reserve the straight edge, and then cut the edge.

It should be emphasized that the common problem of three-roll plate bending machine is that it has straight edges, which can definitely be overcome.
