The rolling machine is widely used in boiler, shipbuilding, petroleum, chemical, hydraulic, metal structure and other machinery manufacturing industries. The roll bending and bending of the rolling machine have the following characteristics:
(1) conical parts can be rerolled by equipment auxiliary equipment, and curling for pipes and profiles can be completed.
Second, the strength of the roll bending is often smaller than the bending and bending, and the cost of the rolling machine is lower than that of the liquid press.
The twists and turns with the successive elastic-plastic twists and turns, smaller tensile force will rebound, thus forming precision, high quality, high efficiency and;
