Performance and Features:
W12NC series curved downward adjustment four roll plate rolling machine can load metal sheet materials in one go without turning the head to complete the pre bending and rolling forming of the sheet metal ends. The remaining straight edges are small, making it an ideal equipment for rolling circular and curved workpieces.
The working roller on this machine is the main driving roller, driven by a hydraulic motor and a reducer. The lower roller can be an auxiliary driving roller driven by a motor or a passive roller. The side roller is a passive roller, and the lifting of the lower roller and side roller is hydraulic transmission. The lifting displacement is controlled by PLC, automatically leveled, and displayed on the screen with digital accuracy of ± 0.15mm. The lower roller performs vertical lifting motion to clamp the sheet metal; There are side rollers on both sides of the lower roller, which can be driven by hydraulic cylinders to perform curved lifting and lowering movements.
The flipping and resetting of the flipping bearing body is driven by hydraulic pressure, and the tail of the upper roller is equipped with a balancing mechanism, which can facilitate the unloading of the rolled workpiece and cylinder. The machine is equipped with a mobile independent operating platform for convenient use by workers and a safety interlock device. It has full functions, high precision, and easy operation. It is the most ideal preferred machine type for rolling circular, curved, and conical workpieces in industries such as petroleum, chemical, boiler, shipbuilding, hydropower, and metal structures.
