Especially the in-well cast-in-place steel pipe concrete support solves problems such as the in-well cast-in-place concrete construction process. The construction is convenient and the bearing capacity is high. Due to in-well requirements, it is often necessary to process various arc-shaped steel pipes, round steel and other items. All along, it has been processed and bent by manually using electric welding to heat the steel pipe to red. This method not only has a large manual labor intensity, but also has no guarantee of the quality of manual processing due to the differences in the arcs of the steel pipe processing, and it is difficult to meet the work requirements. Therefore, this application proposes a vertical steel pipe bending machine to solve the above problems. Content of the Utility Model
