3 Roller Plate Rolling Machine
Three-roller plate rolling machines come in both mechanical and hydraulic variants. The mechanical type includes symmetrical and asymmetrical designs. These machines can roll metal sheets into cylindrical, arc-shaped, and conical forms within certain limits.
Symmetrical
Performance Characteristics of Mechanical Three-Roller Symmetrical Plate Rolling Machine:
This machine features a symmetrical three-roller structure. The upper roller moves vertically at the center between the two lower rollers, driven by a screw, nut, and worm gear system. The lower rollers rotate, powered by a motor. The reducer’s output gear meshes with the lower rollers to provide the necessary torque for rolling the sheet. A downside is that the sheet ends require pre-bending using additional equipment.
Asymmetric
Main Features of Mechanical Three-Roller Asymmetric Plate Rolling Machine:
This machine has an asymmetric three-roller structure. The upper roller serves as the main drive, while the lower roller moves vertically and engages with the upper roller gear through its own gear. The side roller tilts and lifts for pre-bending and rolling functions. The machine is compact, easy to operate, and maintain.
Hydraulic Three-Roller Plate Rolling Machine:
This machine is an upward-adjustable symmetrical three-roller plate rolling machine, capable of rolling metal plates into round, arc, and conical shapes. The two lower rollers act as active rollers, while the upper roller is driven. It's commonly used in industries like shipbuilding, boilers, aviation, hydropower, chemical engineering, metal structures, and machinery manufacturing.
The machine is designed for bending and deforming metal plates, with the ability to roll round, arc, and conical workpieces within a specified range. It includes a pre-bending feature for the plate ends. The lower rollers move horizontally, and the upper roller moves vertically. Transmission shafts use universal couplings.
Working Principle:
The upper roller is centrally positioned between the two lower rollers. Hydraulic oil in the cylinder moves the piston vertically. The main reducer’s final gear drives the lower rollers to rotate, providing torque to the plate. The flat metal plate passes between the three rollers, and through continuous bending, it achieves the desired cylindrical, conical, or arc shape. A limitation is that pre-bending the plate ends requires additional equipment. This machine is ideal for rolling thick plates over 50mm. Additional rollers under the lower rollers enhance accuracy and overall performance.
Folding Types:
Three-roller plate rolling machines are either mechanical or hydraulic. Mechanical variants are further divided into symmetrical and asymmetrical types.
Mechanical Three-Roller Symmetrical Plate Rolling Machine:
The structure is symmetrical with the upper roller moving vertically between the two lower rollers, driven by a screw, nut, and worm gear. The lower rollers rotate, meshing with the reducer’s output gear to provide torque. The drawback is that the plate ends need pre-bending using other equipment.
Mechanical Three-Roller Asymmetric Plate Rolling Machine:
This machine has an asymmetric structure with the upper roller as the main drive. The lower roller moves vertically to clamp the plate, meshing with the upper roller gear. The side roller tilts and lifts for pre-bending and rolling. It is compact, easy to operate and maintain.
Hydraulic Three-Roller Plate Rolling Machine:
The hydraulic version features a vertically adjustable upper roller, powered by hydraulic oil in the cylinder acting on a piston rod. The lower rollers are driven and can be adjusted. This machine can handle metal plates, rolling them into round, arc, and conical shapes. It's widely used in various industries and has pre-bending capabilities for the plate ends. The lower rollers move horizontally, the upper roller moves up and down, and drive shafts are connected by universal couplings.
W11 Series Mechanical Three-Roller Symmetrical Plate Rolling Machine:
The W11 series features a symmetrical structure with the upper roller moving vertically at the center between the lower rollers, driven by a screw, nut, and worm gear system. The lower rollers rotate, meshing with the reducer’s output gear to provide torque. Pre-bending the plate ends requires additional equipment.
W11 Series Mechanical Three-Roller Asymmetric Plate Rolling Machine:
This machine in the W11 series has an asymmetric structure with the upper roller as the main drive. The lower roller moves vertically to clamp the plate, meshing with the upper roller gear. The side roller tilts and lifts for pre-bending and rolling. It is compact, easy to operate and maintain.
W11 Series Hydraulic Three-Roller Symmetrical Plate Rolling Machine:
The W11 series hydraulic machine features a vertically adjustable upper roller powered by hydraulic oil acting on a piston rod. The lower rollers are driven and adjustable. The upper roller’s drum shape enhances product straightness, suitable for long specifications and various cross-sectional shapes of tanks.
