Directly forming square tube unit


Only one set of rolls can continuously produce square and rectangular steel pipes within certain range. It adopts the international advanced multi-radius combined forming process and high-frequency welding, and is formed by multiple symmetrical bending. Specifically, it can be divided into small-side bending, side-side bending, closed free bending, high-frequency welding, finishing and straightening, and sawing to produce pipes with accurate dimensions and excellent quality.


Features

 

Adopting advanced multi-point pre-bending combined forming process, and the rolls are shared. One set of rolls can solve the forming problems of all square and rectangular tubes within a certain range, which can save a lot of roll costs and roll changing time./

        Electric and hydraulic are adopted, and the rollers can be changed quickly

Computer-controlled automatic mode is adopted for changing production specifications. The deformation parts are the four corners of the square tube, no unnecessary deformation process, reducing energy consumption and equipment load
