Easy Operation CNC Control Hydraulic 4 Roller Rolling Machine With High Accuracy
Depends on wind tower size, the rolling machine capacity could be very different. Catering for various demanding, we provide the most suitable rolling machine solution satisfy with the most strictly requirement.
General description of the rolling machine
The W12NC rolling machine has the plate end pre-bending function. It can finish the plate moungting one time, which means it can finish the plate pre-bending and work-piece forming without direction turning.
The machine work roll is main driving roller. The lower roller vertical lifting and both sides rollers adopts hydraulic transmission. The lifting position is controlled by a NC, screen display, synchronization accuracy is ± 0.2mm, turnover bearing body dumping and reset the hydraulic transmission. The tail roller is provided with a balance mechanism, which can facilitate the work-piece and the cylinder body unloading.
The machine is equipped with a mobile type independent operation platform, which is more convenient for workers to use. The machine is is with a safety interlock, making the operation more safety. The machine has the advantages of simple operation, convenient repair, high rolling precision. It is a kind of advanced and practical machine.

Feature of rolling machine:
Four roller rolling machine is the most common, the most accurate, the easiest rolling equipment that people use.
The rear side roller machine can play the role of back gauge in the feed direction.
Any side roll tilt adjustment on the drum mismatch defects is very convenient
The up and lower rollers clamp the plate, so during rolling, the sliding phenomenon does not exist. The flat plate is clamped by the up and lower roller which can accurately avoid the risk of sheet slippage of pre bending and bending operations. When pre bending, there is no need to tilt the plate under the work table level.
Once the plate edge is pre-bended, it can be rolled into a cylinder. Plate cylinder rolling can be carried out on the machine one side. This means that the area occupied by the equipment is small.
One edge of the cylinder is pre-bended, it can directly bending the tail plate edge. (i.e. four roller bending machine can forward bending, and also can rear bending).
Cone rolling is also very convenient. The cone angle depends on the side roller inclining. The lower roller tilts to clamp for feeding.
The lower roller and the two side rollers all adopt two hydraulic lock loop control one-way valve and H valve to ensure that the lower roller and two side rollers can accurately stop at any position.
The lifting and left and right adjusting precision of the lower roller and two side rollers is ± 0.2mm. (side roll tilt lifting leveling precision is ± 0.2mm).
Hydraulic system of the equipment is equipped with over pressure protection. The electrical system is with a circuit breaker over-current protection, overheat,thermal relay overload protection. When the machine is in fault, fault indicator will be on. The main action between the equipment has safety interlock protection.
