English name of plate winder: Plate Rolling Machine or Plate Bending Machine

Principle:

In the central symmetrical position of the two lower rolls, the upper roll of the symmetrical plate winder acts on the piston through the hydraulic oil in the hydraulic cylinder to make a vertical lifting motion, and the last gear of the main reducer drives the two lower roller gears to engage and rotate together to provide torque for the rolled plate. The flat plastic metal plate of the rolling machine passes between the three work rolls (two lower rollers and one upper roll) of the rolling machine, and with the help of the lower pressure of the upper roll and the rotating movement of the lower roll, the metal plate undergoes multi-pass continuous bending (inner layer compression deformation, middle layer unchanged, outer layer tensile deformation), resulting in permanent plastic deformation and coiling into the required cylinders, cones or part of them. The disadvantage of the hydraulic three-roll plate winder is that the end of the plate needs to be pre-bent with the help of other equipment. The machine is suitable for large plate coiler whose thickness is more than 50mm. A row of fixed idlers is added to the lower part of the two lower rollers to shorten the span of the two lower rollers, thus improving the accuracy of the coiling workpiece and the overall performance of the machine.

Three-roll plate winder

1. Mechanical three-roll plate winder is divided into symmetrical and asymmetric.

Mechanical three-roll symmetrical type

The performance characteristics of the mechanical three-roll symmetrical plate winder: the structure of the machine is three-roll symmetrical type, and the upper roll moves vertically in the central symmetrical position of the two lower rollers, which is obtained by the screw mother worm drive, and the two rollers move in rotation. The output gear of the reducer engages with the lower roll gear to provide torque for the rolled plate. 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-roll asymmetric type

The main features of the mechanical three-roll asymmetric plate winder are as follows: the structure of the machine is three-roll asymmetric, the upper roll is mainly driven, and the lower roll moves vertically in order to clamp the plate, and meshes with the upper roll gear through the lower roll gear, which is used as the main transmission at the same time; the side roll moves up and down, which has the dual functions of pre-bending and winding circle. Compact structure, convenient operation and maintenance.

2. Hydraulic type

The main features of the hydraulic three-roll symmetrical plate winder: the upper roll of the machine can be vertically raised and lowered, and 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 by rotation, and the output gear meshes through the reducer to provide torque for the rolling plate, and the lower roller has a supporting roller and can be adjusted. The upper roll is in the shape of a drum to improve the straightness of the products, which is suitable for super-long cans with various cross-section shapes.

For the upward adjustment symmetrical three-roll plate winder, the metal plate can be rolled into round, curved and conical workpieces in a certain range. The two lower rollers are active rollers and the upper rollers are driven rolls. 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 plate, it can roll round, curved and conical workpieces within a certain range, and has the function of pre-bending at the end of the plate. the two lower rollers of this machine can be moved horizontally, and the upper roller can move up and down. The movement modes are mechanical and hydraulic, and the transmission shafts are connected by universal couplings.

What are the advantages of the plate winder?

Plate winder (Rolling Machine) is a plastic machine tool for continuous point bending of plates, which has the function of rolling plates with different shapes, such as O-shape, U-shape, multi-segment R and so on. Three-roll plate winder has mechanical and hydraulic type: mechanical three-roll plate winder is divided into symmetrical and asymmetric. The sheet metal can be rolled into circular, curved and conical workpieces within a certain range.

Does China have a super large plate winder for nuclear submarines?

Yes.

The world’s largest three-roll plate winder was born in Ezhong, Hubei. The world’s largest three-roll plate winder with a maximum reduction force of 8160 tons was born in Hubei Ezhong heavy Machinery Co., Ltd.

The plate winder belongs to a three-roll plate winder, which is 11.8m long, 8.83m wide and 9.78m wide, with a maximum reduction force of 8160 tons, a self-weight of 9000 tons (excluding hydraulic and electrical equipment), a maximum thickness of 400mm and a maximum width of 3000 mm. The plate winder is divided into three parts: mechanical, hydraulic and control, which can not only display the real-time pressure, but also accurately control the pressure.

What are the models of Xintang silver roll plate?

The models of Xintang silver roll plate are Q235A, Q235B, Q235C, Q255A, Q275, Q345B, Q345C; the types of coiling machines are different due to different fields of use. In terms of the number of rolls, it is divided into three-roll plate winder and four-roll plate winder. Three-roll plate winder is divided into symmetrical three-roll plate winder, horizontal downward adjustment three-bar plate winder, arc downward adjustment plate winder, upper roll universal three-roll plate winder, hydraulic numerical control plate winder. It is divided into mechanical type and hydraulic type from the transmission. In terms of the development of the plate winder, the upper roll universal type is the most backward, the horizontal downward adjustment mode is slightly advanced, and the arc downward adjustment mode is the most advanced.
