Production of a variety of solid seamless automatic winding machine is a hydraulic structure is reasonable, compact, great endurance in the roll radial force, the solid shaft is not easy to produce plastic deformation. Stiffness, high strength, high precision rotary drum, solid shaft diameter ratio coefficient, axial force in the large deformation is not easy to produce this structure has obtained national patent. The factory produced a variety of hydraulic automatic winder unit and strip for cold rolled strip steel pickling, annealing coating, plastic and other precision straightening machine group.
