Most 3-roller plate rolling machines are mechanical plate bending machines. Of course, there are also hydraulic plate bending machines, but all four-roller plate bending machines are hydraulic plate bending machines. The structure of the mechanical three-roller symmetrical plate bending machine is three-roller symmetrical. The upper roller moves vertically up and down through bevel gear transmission at the symmetrical position in the center of the two lower rollers. The final gear of the main reducer drives the two lower roller gears to mesh and rotate. Movement to provide torque for rolled sheets. The plastic metal plate with flat specifications passes between the three working rollers (two lower rollers and one upper roller) of the plate bending machine. With the help of the downward pressure of the upper roller and the rotational movement of the lower roller, the metal plate is continuously bent in multiple passes. Produce permanent plastic deformation and roll into the required cylinder, cone or part thereof.
The disadvantage of the mechanical 3-roller plate rolling machine is that the ends of the plate need to be pre-bent with the help of other equipment. The structure of the hydraulic three-roller symmetrical plate bending machine is a three-roller symmetrical type. The upper roller is at a symmetrical position in the center of the two lower rollers. The hydraulic oil in the hydraulic cylinder acts on the piston to perform vertical lifting and lowering movements. The final gear of the main reducer drives the two lower rollers. The lower roller gear meshes into a rotational motion to provide torque for rolling the sheet. The plastic metal plate with flat specifications passes between the three working rollers of the plate rolling machine. With the help of the downward pressure of the upper roller and the rotational movement of the lower roller, the metal plate is continuously bent through multiple passes to produce permanent plastic deformation and is rolled into The required cylinder, cone or part thereof. The disadvantage of the hydraulic three-roller symmetrical plate bending machine is that the ends of the plate need to be pre-bent with the help of other equipment. The hydraulic three-roller symmetrical plate rolling machine is suitable for large plate rolling machines with a plate thickness of more than 50mm. A row of fixed rollers is added under the two lower rollers to shorten the span of the two lower rollers, thereby improving the accuracy of the rolled workpiece and the overall machine performance.
Three-roller plate bending machine
Three-roller plate rolling machines are available in mechanical and hydraulic types: Mechanical three-roller plate rolling machines are divided into symmetrical and asymmetrical mechanical three-roller symmetrical plate rolling machines: Mechanical three-roller symmetrical plate rolling machines Performance characteristics: The machine structure The type is a three-roller symmetrical type. The upper roller performs vertical lifting movement at the symmetrical position in the center of the two lower rollers, which is obtained by the screw nut and worm drive. The two lower rollers perform rotational movement and mesh with the lower roller gear through the output gear of the reducer. Provides torque for rolled sheets. The disadvantage of this machine is that the end of the plate needs to be pre-bent with the help of other equipment.
Mechanical three-roller asymmetric plate rolling machine
The main features of the mechanical three-roller asymmetric plate rolling machine: The structure of the machine is a three-roller asymmetric 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. , and serves as the main drive at the same time; the side roller performs tilting and lifting movements, and has dual functions of pre-bending and rolling. Compact structure, easy operation and maintenance. Technical Parameters: Specifications, Models, Maximum Thickness of Coiled Plate.
Hydraulic 3-roller plate rolling machine
The main features of the hydraulic three-roller symmetrical plate bending machine: the upper roller of the machine can be lifted vertically. The hydraulic transmission of vertical lifting is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston rod; the lower roller is driven to rotate and meshed with the output gear of the reducer. To provide torque for the rolling plate, there is a supporting roller under the lower roller and it is adjustable. The upper roller is in the shape of a drum, which improves the straightness of the product and is suitable for ultra-long specifications and various cross-sectional shapes. The can is an upward-adjustable symmetrical three-roller plate rolling machine, which can roll metal sheets into circles, arcs and cones within a certain range. Shape workpiece, the two lower rollers of this machine are driving rollers, and the upper roller is driven roller. It is widely used in shipbuilding, boiler, aviation, hydropower, chemical industry, metal structure and machinery manufacturing industries. It is suitable for bending and deforming metal sheets. It can roll round, arc-shaped and tapered workpieces within a certain range, and has a plate end pre-bending function. The two lower rollers of this model are driving rollers and can move horizontally. The roller is a driven roller and can move up and down. The movement methods include mechanical and hydraulic. The transmission shafts are connected by universal couplings.
