1. Mechanical

Three-roller bending machine is divided into symmetrical and asymmetrical.

Mechanical three-roller symmetry

Performance characteristics of mechanical three-roller symmetrical plate bending machine: The structure of the machine is three-roller symmetrical. The upper roller moves vertically at the central symmetrical position of the two lower rollers. It is obtained by the transmission of the screw screw nut and the worm. Rotational motion, through the output gear of the reducer meshing with the lower roller gear, provides torque for the rolled sheet. The disadvantage of this machine is that the end of the plate needs to be pre-bent with other equipment.

Mechanical three-roll asymmetrical

The main features of the mechanical three-roll asymmetrical plate bending machine: the structure of the machine is a three-roll asymmetrical type, the upper roller is the main drive, and the lower roller moves vertically to clamp the plate and mesh with the upper roller gear through the lower roller gear , At the same time as the main drive; the side rollers are tilted and lifted, with dual functions of pre-bending and rounding. Compact structure, convenient operation and maintenance.

2. Hydraulic

Hydraulic

The main features of the three-roller symmetrical plate rolling machine: the upper roller can be vertically lifted, and the vertical lifting hydraulic transmission is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod; the lower roller is driven in rotation, and the output gear of the reducer is meshed for the roll The plate provides torque, and there is a supporting roller under the lower roller, which can be adjusted. The upper roller is in the shape of a drum, which improves the straightness of the product and is suitable for ultra-long tanks with various cross-sectional shapes.

It is an upward adjustment symmetrical three-roller plate bending machine

, It can roll the metal sheet into round, arc and conical workpieces within a certain range. The two lower rollers of this model are the driving rollers and the upper roller is the driven roller. It is widely used in shipbuilding, boiler, aviation, hydropower, chemical, metal structure and machinery manufacturing industries.

It is suitable for the bending deformation of metal plates. It can roll round, arc and tapered workpieces within a certain range, and has the function of pre-bending the end of the plate. The two lower rollers of this model are active rollers that can move horizontally. The roller is a driven roller that can move up and down. There are mechanical and hydraulic movement modes. The drive shafts are all connected by universal couplings.
