W12 12x4000 sheet rolling machine , 4 roller sheet rolling machine with CNC PLC control system
Four Roller Plate Rolling Machine. It wide used in the manufacture of pressure vessels, machinery, hydropower, construction and other industries of the barrel body per-bending, roll round, and also gave a function of checking circle and leveling.
The top roller driven by hydraulic motor. Through the friction between the metal plate and the top roller to drive the bottp, roller and side roller rotate. And supply the torque for bending plate. The botto, roller, side roller move along with an arc. The bottom roller rising to clamp the plate and the side roller title up to pre-bend the end of the plate.
1. controlled by the microcomputer automatically
2. Working rollers are made of high-quality 45 # forging with high strength, strong abrasion and longer working hour.
3. Roll bearings at the end of roller are rolling bearings which have low friction coefficient.
4. Lifting displacement of the bottom roller and side roller is controlled by the microcomputer. Digital display on the screen. The accuracy of moving synchrony is ±0.2mm.
5. The bottom roller and side roller can make single end inclination.
6. movable worktable. The positions of the working rollers are displayed on the touching screen.
7. high-speed PLC intelligent programmable controllers from Mitsubishi Corporation in Japan. Man-machine conversationfunction, fault self-diagnosis, strong anti-interference.
8. The sensor of lifting displacement of the bottom roller and side roller is high-precision sensor.
Hydraulic system provides power to lift bottom and side rollers through driving cylinders, also controls tilting cylinder up and down. The hydraulic system works reliable with reasonable design. In order to guarantee oil clean, system is equipped with oil sucking & returning filters with high accuracy. The radial quick joints particularly used in metallurgical & mining are applied in the hydraulic pipes and valves to avoid leaking.
The main valves of the hydraulic system are the products of the Taiwan Northman Co., Ltd. or abroad. Pump oil filters, motors and seals are products of famous producers inland. All of them are advanced performances and reliable quality. All hydraulic parts have passed strict inspection and test to eliminate hidden trouble before usage.
System pipes with over load protection are well arranged to easily operate and act flexible.
The whole structure of Hydraulic Plate rolling machine
1. Totally European design,streamlined looking,frames of our machines are fabricated, welded steel (ST-52). Roll shafts, materials and bearings used in production are European quality. Also the torque limit of the machines is very high. NC playback and CNC graphic control systems are available as optional accessory.
2. The main structure of the equipment includes upper roller, lower roller and horizontal movement mechanism, supporting mechanism,main drive mechanism,downturn system, left and right machine frame, chassis and balance mechanism, hydraulic and electrical control systems.
3. It allows for excellent roundness, thanks to the Planetary movement of the side rolls (Accurl patent), moving them to the center of the machine (the tightest geometry available), compared to the inclined linear guides of other brands that, especially on large diameters, move farther away from the central roll and the plate clamping.clamping pressure is adjustable(no-existent skidding,productivity is 80% than three roller plate rolling machine).
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. Welding structure: racks, chassis, wheel box.
3. Plate into the factory (chemical composition analysis, mechanical properties test) — pretreatment — for sheet metal cutting-welding-seam UT or RT flaw — annealing treatment — roughing-finishing— vibration destressing—hot blasting —finishing
