Pre bending machine

After milling, the steel plate is sent to the upper and lower dies of the C-shaped press section by section. Through the relative closure of the upper and lower dies, plastic deformation occurs at the plate edges on both sides of the steel plate, and a small arc section with straight edge length not greater than the plate thickness and radius similar to the finished steel pipe is pre bent. The pre bending machine supplied by Shuangyou has many functions, such as automatic feeding, automatic centering, pre bending forming and automatic discharging. It can complete the pre bending forming of large longitudinal submerged arc welded pipe continuously, in real time, with good quality and low consumption.
