Mechanical 3-Roll Symmetrical Bending Machine

Mechanical 3-Roll Symmetrical Bending Machine

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

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.

working principle

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.

Type

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.

Mechanical Three-Roll Asymmetrical Bending Machine :

Mechanical three-roller asymmetrical plate bending machine Main features: The machine structure type is three-roll asymmetric type, the upper roller is the main drive, the lower roller vertical lifting movement to clamp the plate, and through the lower roller gear meshes with the upper roller gear At the same time as the main drive; side roller for tilting movements, there are pre-bend and roll circle dual function. Compact structure, easy operation and maintenance. Technical parameters: Specification model roll thickness.

Hydraulic Three-Roller Bending Machine:

The main features of the Hydraulic Three-Roller Symmetric  Bending Machine are: the upper roll of the machine can be vertically lifted, and the vertical lift is hydraulically driven, and the piston rod is acted by the hydraulic oil in the hydraulic cylinder; the lower roll is driven to rotate, and the lower roll has a supporting roll, and adjustable.

Hydraulic Three-Roller Bending Machine is an up-regulating symmetric three-roller bending machine, which can roll metal plates into round, arc and conical workpieces within a certain range. This model uses two rollers as the active roller and the upper roller as the driven roller. It is widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure and machinery manufacturing industries.

Hydraulic Three-Roller Bending is suitable for the bending deformation of metal plates, can be rolled round, arc and a conical workpiece within a certain range, and has the pre-bending function of the end of the plate, the two lower rollers of this model can be horizontally moved by the driving roller. The upper roller can be moved up and down by the follower roller. The moving mode is mechanical and hydraulic. The drive shaft is connected by a universal coupling.
