►The machine belongs to 4 Roll Plate Bending Machine ( 4 Roll Plate Roller ), used for cylinder pressure vessel manufacturing industries, it has function of roll round, pre-bending, correct the circle, with coarse leveling function.
►The upper roller is the main transmission, leading the lower roller and the side roller move by friction between the sheet plate and the upper roller, meanwhile, the upper roller provides torque for rolling rollers.
►The upper roller is the active roller by hydraulic transmission, lower roller and the accessories, both sides turn plane and supporting roller lifting are driven by hydraulic pressure.
►The lower roller use vertical lifting, the side roller use tilt lifting, so the synchronization precision error is less than 0.15mm.
►To make prebending, the lower roller rising and clamping the sheet plate, the side roller inclined upward, plate end pre-bending done.
►According to the arrangement of the side roller to adjust the position of the two sides, four roller rolling machine can do symmetric or non-symmetric bending, so the machine can be a rolled ideal very small arc straight edge into theory of surplus. If compared with the symmetrical three roller bending machine, four roller rolling machine do not need to use pre-bending plate press any more.
►The lubricating point of the machine use cut-up arrangement.
►The four-roller rolling machines’ control system adopted Japan OMRON intelligent high-speed PLC industrial control machine, the system can control lower roller, and the other roller accessories.►The lower roller and the two side roller’s displacement sensor using encoder, so the action design of the sensor is reasonable, which can guarantee the service life.
►All bearings used in the four-roller rolling machine are required to adopt the most advanced technology, the most well-known manufacturers of leading products.
►Hydraulic cylinder with accuracy manufacturing, good sealing effect, so the cylinder reduce the pressure relief and leakage of sealing device, in addition, all sealing accessories imported from abroad.
