automatic hydraulic CNC 4-roller metal sheet plate bending rolling machine with CE

Machine Features
The equipment has the pre-bending function of the plate end and the CNC rolling function. It can feed the metal plate at a time, and can complete the pre-bending and the roll forming of the workpiece without turning the head. The upper working roll of the machine is the main drive roll, and the lower roll and both sides of the roll are hydraulically driven. The lift displacement is controlled by the computer and is automatically leveled. The screen display shows the synchronization accuracy of ±0.1mm. The tilting and resetting of the rollover bearing body is hydraulic transmission, the balance of the upper roll is equipped with a balance mechanism, which can easily take out the rolled workpiece. It has a mobile stand-alone console that can be moved at any time; the machine is equipped with a safety interlocking device and is safe. Due to its full-featured, high-precision, and easy-to-use operation, this device is the ideal contemporary CNC coiling device. It is the ideal model for rolling circular and arc-shaped workpieces in energy, transportation, petroleum, chemical, boiler, shipbuilding, hydropower, and metal structure industries. 2）CNC control system: 1. Special bending aircraft, numerical control. 2. HMI (human machine interface), intelligent operation. 3. Self-compensating, single operate, high efficiency, safe and convenient. 4. Many models for choice, economic numerical control model, TC computerized numerical control. 3）.Major parts of the manufacturing process : 1. Working rollers: cast steel ingot (chemical composition analysis): check performance-forging roughcast — forging annealing-UT flaw — roughing (mechanical tests)-heat treatment (hardening and tempering) — UT flaw — semi finishing — finishing — MT. 2. Large forgings: cylinder body, gear, gear shaft forging roughcast — surface inspection – roughing — UT flaw — UT flaw detector heat treatment — finishing semi—finishing — MT. 3. Welding structure: racks, chassis, wheel box 4. Plate into the factory (chemical composition analysis
