This series of winding machine is suitable for the winding work of the plate. When rolling, the metal sheet material can be rolled into a cylinder shape first, and then welded, can be made into ventilation, water, smoke exhaust, exhaust and other functions of the pipeline, hardware products. This product has the characteristics of small size, simple structure, easy operation, light weight, easy to move, etc. (by its can be made into universal shaft type according to customer requirements). Processing features: roll plate is suitable, parts deformation uniform, after processing, parts can be fully stress diffusion, not easy to make the surface production hardening phenomenon, can maintain the original performance of the plate, greatly better than the manual beating into the pipeline, so widely used.
