Mechanical 3-Roll Symmetrical Bending Machine Features:
The structure type of the machine is three-roller symmetry type. The upper roller is vertically lifted and moved symmetrically at the center of the two lower rollers. It is obtained through the wire rod screw worm drive, and the two lower rollers are rotated and driven by the motor. The torque is supplied to the rolled plate by meshing the output gear of the speed reducer with the lower roller gear.
The disadvantage of this machine is that the end of the sheet needs to be pre-bent by means of other equipment.

Hydraulic 3-Roll Bending Machine
Hydraulic 3-roll Bending Machine is an up-regulating symmetric 3-roll bending machine . It can roll metal plates into round, curved and conical workpieces. The two lower rollers are driven rollers and the upper roller is driven rollers. Widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure and machinery manufacturing industries.
Hydraulic 3-roll Bending Machine is suitable for the bending deformation of metal sheet, can be rolled round, arc and a certain range of conical workpieces, there is a plate pre-bending function, the model of the two lower rollers for the initiative roller can be horizontally moved, The upper roller is a follower roller that can move up and down, and the drive shafts are connected by a universal coupling.
The upper roller of the coiling machine acts on the piston in the symmetrical position of the two lower rollers by the hydraulic oil in the hydraulic cylinder to perform vertical lifting movement. The gears of the lower gears driven by the final gear of the main reducer engage the cooperative rotary motion of the two lower roller gears to provide torque for rolling the plate. . The flat metal plate of the coiling machine passes through the three work rolls (two lower rolls and one upper roll) of the coiling machine, and the metal plate passes through multiple passes by means of the lower roll of the upper roll and the rotation of the lower roll. Continuous bending, producing permanent plastic deformation, rolling into the desired cylinder, cone or part thereof. The disadvantage of the hydraulic three-roller coiler is that the end of the sheet needs to be pre-bent by means of other equipment. The coiling machine is suitable for large coiling machines with a coil thickness of more than 50mm. A fixed row of idler rollers is added at the lower part of the two lower rollers to shorten the span of the two rollers, thereby improving the accuracy of the rolled workpiece and the overall performance of the machine.
The 3-Roller Bending Machine has mechanical and hydraulic type:
The Mechanical 3-Roll Bending Machine is divided into symmetrical and asymmetrical.
Mechanical Three-Roller Symmetrical Bending Machine: Mechanical Three-Roll Symmetrical Bending Machine Features: The machine is of three-roll symmetrical type. The upper roller moves vertically at the symmetrical position of the two lower rollers through the wire. The female worm gear drives and the two lower rollers make a rotary motion, and mesh with the lower roller gear through the output gear of the speed reducer to provide torque for rolling the plate. The disadvantage of this machine is that the end of the sheet needs to be pre-bent by means of other equipment.
