4 Roll Bending Machines For Steel Pipes

1. Introduction of 4 Roll Bending Machines

The W12 CNC series automatic 4-roll bending machine features advanced technology, automated rolling programming, intelligent control, and a fully hydraulic drive, enabling automated rolling. It is a highly efficient machine for batch rolling circular, multi-segment arc, square, conical, and special-shaped workpieces.

2. Structure of 4 Roll Bending Machines

The main body structure of the machine is composed of the upper roller device and driving device, lower roller device, side roller device, hydraulic drop end device, the lubrication device, the Left and right frames, chassis, etc.

3. CNC Controller System of 4 Roll Bending Machines

The system adopts a rotation encoder, matched with a high-reliability industry controller, which builds up a control system of stable performance.

Automatic Self-judge function.

The CNC system is of real-time monitoring, data passing, and power off memory during the process of rolling.

The industry control PLC will inspect the lower position and the two ends of the side roller position automatically and control it to ensure synchronization precision  ±0.15mm.

Programmable display shows real-time lower roller position and the two ends of the side roller

position and it can be set.

Displacement transducer resolution is 0.10mm, and display precision is ±0.10mm.

4. Application of Roll Bending Machines

4-roll bending machines are widely used in pipe mass production, steel structure buildings, shipbuilding, the boiler industry, and the petroleum and gas pipes industry.
