The two-roller is designed for metal and curved cylinders. The two-roller is mainly used for coiling steel plates. It can quickly manufacture thin-walled pipes, ventilation pipes, chimneys, filters, automobile exhaust pipes, and liquid storage ( Gas cylinders, etc., two-roller coiling machine is one of the main equipments in the boiler, shipbuilding, petrochemical, cement, motor and machine manufacturing industries.
The upper roller of the two-roller is a rigid roller, and the lower roller is a flexible roller. When the lower roller is pressed by the upper roller, there is a certain radial concave deformation, when the steel plate is fed between the upper roller and the lower roller. It will be rolled into a cylinder by two rolls. From a microscopic point of view, the rolled cylinder is actually composed of numerous small arcs. The two-roller CNC hydraulic automatic bending machine completely changed the rolling method of the three-roll bending machine, and removed the processes of pre-bending, centering, winding, and rounding. The two-roller CNC hydraulic automatic bending machine is easy to operate and approximate. No straight edge, one molding, high efficiency.
