What is Plate Rolling Machine?

The plate rolling machine is a kind of equipment that uses work rolls to bend sheet metal. It can form parts of different shapes, cylindrical and tapered. It is essential processing equipment. The working principle of the plate bending machine is to move the work roll through the action of hydraulic pressure, mechanical force, and additional external parties to make the plate bend or bend into shape. According to the rotation, movement, and position changes of work rolls of different forms, the plate rolling machine can process parts such as the oval, arc, and cylindrical elements.

FAQ

In the W11 series Symmetrical plate rolling machine, the upper roller of the W11 series Symmetrical scale rolling machine uses the hydraulic oil in the hydraulic cylinder to act on the piston to move vertically at the central symmetrical position of the two lower rollers. Provide torque for rolled sheets. The flat plastic metal plate of the bending machine passes between the three working rolls (two lower rolls and one upper roll) of the bending machine. With the help of the lower pressure of the upper roll and the rotation of the lower roll, the metal plate is passed through multiple passes. Continuous bending (the inner layer is compressed and deformed, the middle layer is unchanged, and the outer layer is stretched and deformed) to produce permanent plastic deformation and roll into the required cylinder, cone, or part of them. The disadvantage of this hydraulic three-roller bending machine is that the end of the plate needs to be pre-bent with the help of additional equipment. This rolling machine is suitable for large, more than 50mm thick devices. A row of fixed idlers is added under the two lower rollers to shorten the span of the two lower rollers, thereby improving the precision of the rolled workpiece and the machine’s overall performance.

The position of the upper roller of the W12 series plate bending machine is fixed, and the lower roller moves upward linearly to clamp the steel plate. The rollers on both sides transfer in a straight line or arc to move closer to the roller to adjust the radius of curvature of the reel. The four-roller and three-roller rolling machines have different roller motion forms, but the working principle is the same; they use the three-point fixed circle principle to carry out different radii moving. However, the pre-bending straight edge and roundness of the four-roller bending machine are better than those of the three-roller.

The type of plate bending machine varies depending on the field of use, from the transmission point of the mechanical type and hydraulic type. From the number of rolls, it is divided into three-roller and four-roller. The three-roller is divided into a symmetrical three-roller bending machine, asymmetrical three-roller bending machine, horizontal downward adjustment three-roller bending machine, W11S upper-roller universal bending machine, and four-roller CNC turning machine. In terms of the development of the plate bending machine, the upper-roller universal type is the most backward, and the four-roller CNC bending machine is the most advanced. Currently, the most commonly used in the market are the W11F partial Samsung plate bending machine, W11S upper-roller universal plate bending machine, W11 mechanical symmetrical plate bending machine, and W12 four-roller plate bending machine.

The mechanical type is divided into W11F asymmetrical plate rolling machine and W11 series symmetrical plate rolling machine.

Performance and characteristics of W11 series symmetrical plate rolling machine:
The structure of the machine is three-roller symmetrical type. The upper roller moves vertically at the symmetrical position of the two lower rollers. It is obtained by the transmission of the screw and screw nut. The two lower rollers rotate through the output gear of the reducer and the lower roller. The gears mesh to provide 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.

Performance and characteristics of W11F asymmetrical plate rolling machine:
The structure of the machine is a three-roller asymmetrical type. The upper roller is the main drive, and the lower roller moves vertically to clamp the plate. The lower roller gear meshes with the upper roller gear and serves as the main drive at the same time; the side rollers are tilted and lifted. , With dual functions of pre-bending and rolling. Compact structure, convenient operation and maintenance.

The hydraulic type is divided into W11S upper roll universal type and W12 four-roller plate bending machine:

The main features of W11S upper roll universal type: The upper roll universal bending machine adopts the upper roll lifting hydraulic drive and horizontal movement (mechanical transmission), driven by the lower roll, and the electric centralized
