Bending of plates uses work rolls to bend the sheet into shapes, which can form cylindrical parts, tapered parts and other parts of different shapes.
The working principle of bending of plates is to move the work roll through the action of hydraulic pressure, mechanical force and other external forces, so that the sheet is bent or rolled into shape.
Bending of plates can process elliptical parts, arc-shaped parts, cylindrical parts and other parts according to the rotation movement and position changes of work rolls of different shapes.

The most practical, accepted, and economical way to make large-radii bends generally is to cold-roll the material. Many variables have a bearing on the type of equipment you should choose, including wall, flange, and leg thickness.
For large-radii bends, cold rolling achieves the desired radius with a minimum number of passes. Because of their size, wide-flange beams can be cold-rolled as well.
Because the workpiece can be extremely thick and strong, you need to understand the variables and learn how to work with them.
In the absence of a professional profile bending machine (also called angle bending machine or section bending machine), we can use a 3-roller plate bending machine to bend angle iron.
High efficiency! 2-roller plate bending machine generally can reach 100-350 pieces/h, up to 1000 pieces/h.The parts have high precision & good surface quality.
Roll forming is a method in which the sheet material is placed in 2-4 rollers of the plate bending machine, and the sheet material is bent and formed along the roller as the roller rotates.
Manufacturing process of pressure vessels includes material, scribing, blanking, bending of plates, forming, edge processing, assembly, welding, inspection, etc
