The hydraulic symmetrical 3-roll rolling machine has 3 symmetrically arranged rolls. The upper roll is located at center of two lower rolls and is directly driven by dual hydraulic cylinders to move vertically. The output gear on main speed reducer is used to mesh the gears of both lower rolls for rotation so as to provide torque for rolling plate. Metal plate is located among three working rolls and subsequently continuously bent under pressure of upper roll and rotation of lower rolls to generate permanent plastic deformation on plate so as to roll the plate to required shape such as cylinder, taper cylinder or arc.
The disadvantage of hydraulic 3-roll rolling machine is the end of plate can not be bent preliminarily but pre-bending can be realized during rounding. The vertical moving of upper roll is monitored by a displacement sensor and shown by a digital meter, so the displacement and position of upper roll can be directly observed and working efficiency and product quality are therefore increased.
