2. Description:
This is hydraulic upper roller symmetrical adjust 3-roller rolling machine, upper roller elevating vertically at center symmetry position of two lower roller, that through hydraulic oil act on piston to get hydraulic driving; the two lower roller rotating, joggle with lower roller gear through output gear of speed reducer, to provide torque for plate rolling. The shortage of this machine is the end of plate should be prebended by other machines.
Pre-bending is available by means of direct pressure from top-roller that can be adjusted in four directions - upwards, downwards, right, left. Cone-bending function is also available by adjustment of two ends of top roller to make top roller inclinable, so that one end is in low position, another is in high position, with the help of cone-bending device, the machine can carry out cone bending.
The required cone angle can not be reached in one time of operation, it needs some operations through gradual adjustment of the declining angle of top roller. During the operation, workpiece lies on the bottom rollers, the workers do not have to buttress it, so workers are safe and easy to run the machine.
