Four Roller Plate Rolling Machine

Supplier: Nantong Reliantt Co., Ltd.

The Four Roller Plate Rolling Machine of Nantong Reliantt Co. which has the functions of pre-bending & rolling, also it can level the plate.


W12NC Series Four-Roller Plate Rolling Machine is of the hydraulic style which extensively used for pre-bending & rounding as making the pressure vessel, machine, water and electricity, building etc, at the same time, it equips with the function of sizing & straightening.

Both the upper & lower rollers are the main drive for rotating & the offset rollers are rotating by the friction between the steel plate and the rollers so that they can provide the torque for rounding.

The main drive adopts the hydraulic motor instead of the reduction gear.

The upper & lower rollers for main drive takes hydraulic drive and the movement for lower roller, offset rollers & tipping device takes hydraulic drive.

The lower roller can move up & down vertically while the offset rollers move up & down slantways with ±0.15mm precision for synchronization.

The end pre-bending with high precision is finished by ascending the lower roller for clamping the steel plate and ascending the offset rollers.

As the upper roller is in the shape of drum, it accompany of the adjustment for the lower roller & offset rollers, so that it can get the ideal effect for rounding in the appointed thickness scope.

In order to gain the high efficiency, the up & down movement for lower roller & offset rollers are finished by the NC control, therefore it is easy for one worker to operate the machine.

Four rollers type plate bending rolls, with high precision products, and more convenient for operating.
