Ship Plate Bending Machine

The marine three roll bending machine

The shipboard rolling mill adopts a three-roll symmetrical structure. The upper roller moves vertically at the center symmetrical position of the two rollers. The hydraulic drive is realized by the effect of the oil in the cylinder on the position. The two lower rollers rotate and provide torque for the plate through the meshing of the gear of the reducer and the gear of the lower roller. Multiple sets of support rollers are designed on the underside of the two lower rollers to enhance the rigidity of the lower rollers and can be adjusted vertically. On the upper side of the upper roller, there is a rigid beam. In addition, multiple sets of support rollers are arranged between the beam and the upper roller to improve the rigidity of the upper roller. The machine is suitable for bending of curved and over-wide workpieces.

The Details Of EZHONG ShipPlate Bending Machine

- Individual Roll Driven: Two bottom rollers are driven by the individual reducers, which avoid mechanical interference, extend the service life of the working rolls, and improves the out-surface quality of the workpiece.

- Flexing Compensation: There is an adjustable backup roll device between the upper beam and upper back-up rollers, or the bottom beam and the bottom back-up rollers, which function is to compensate for the rolling deformation. This device is driven by the plunger-type cylinder. A load of compensation is set by the deformation performance curve, which guarantees high straightness of the workpiece while processing the plates in different thicknesses and widths.

- Mutable Center Distance: Adopting the technique of mutable center distance between the two bottom rollers, the aim is to reach a wider range and higher precision for rolling plates.

- Horizontal Moving: The bottom roll seat and each group of backup roll seats are connected with the horizontal-moving reducers in the same specification, and the horizontal moving reducers join together through the universal joint as to move synchronously. Adopting mechanical moving one way makes the oil cylinders be synchronous, the other way owns the advantage of excellent self-locking performance.

- Control System: The system can work in both rolling and bending, and the two ways convert to each other conveniently. This system has features of powerful anti-interference ability, adaption to the severe industrial environment and sufficient extending capacity, etc.
