Performance characteristics:
The structure of the four roll plate rolling machine is four roll type, with the upper roll as the main transmission. The output gear of the reducer meshes with the upper roll gear to provide torque for rolling the plate; The lower roller performs vertical lifting and lowering motion, which is obtained by the hydraulic oil in the hydraulic cylinder acting on the piston to clamp the plate, and is hydraulic transmission; There are side rollers on both sides of the lower roller, which tilt along the frame guide rail and are driven by a screw and worm gear; The advantage of this machine is that the pre bending and rounding of the sheet ends can be carried out on the same equipment.

working principle:
W12CNC:
series four-roller plate rolling machine, is the introduction of German advanced technology production, PLC program mable digital control, full hydraulic drive, the realization of the automation of the four-roller CNC plate rolling machine. The machine has advanced structure, superior performance, good precision, high efficiency and convenient operation, leading technology among similar products in the world. The position of the upper roll is fixed while the lower roll moves up in a straight line to clamp the steel plate. The two side rollers move up in a straight line to adjust the curvature radius of the drum, which can feed the metal sheet once and complete the prebending and rolling of the sheet end without turning. Batch rolling using automatic mode, with the batch of workpiece molding consistency is good. It is the ideal equipment for rolling cylindrical, curved, conical, rectangular and other shaped workpieces. Is the metallurgy, building materials, petroleum, chemical industry, water conservancy, electric power, bridge, coal, mining, shipbuilding, boiler, aviation, environmental protection, metal structure and other industries roll round the preferred model.
