DRW12 Series 4-rolls Hydraulic Bending Machine
Drw12 Series 4-Rolls Hydraulic Bending Machine / Rolling Machine / Plate Roller / DURAMA Metal Rolling Machine The Feature of DRW12 Series Hydraulic 4-rolls Plate Rolling machine : The DRW12 series 4-rolls plate rolling machine are widely used in in petroleum, chemical industry, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, power transmission towers and other machinery and equipment etc.
Its working principle is rotating bending deformation. For the upper roller can be moved no matter up or down, but also horizontally, so no need additional press or equipment, can realize pre-bending, bending, as well as correction of the work piece. The whole structure of Hydraulic 4-rolls 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.The model DRW12 has both the upper and the lower roll powered with hydraulic motor and planetary gear box. The Feature of Hydraulic 4-rolls Plate Rolling machine : 1. High precision pre-bending, freely setup the width of plate. Upper roller presses the plate end for pre-bending.
2. Upper roller likes drum with collaboration of carrier roller permit continual bending of any thickness of plate.
3. Safe work, fixed two down roller, upper roller does horizontal and vertical movement, and the plate don't move during upper roller moving.
4. Unitary structure, convenient to move the whole machine as machine has a hardy under pan. No need to anchor bolt.
5. Different use has different control way, like top numerical control and below numerical control.
6.Through exclusive technology, DURAMA can develop cones as easily as competitive machines can develop cylinders. And it eliminates scarring on the surface of shell or roll and also eliminates, in most cases, the need for grinding the lamination (bull nosing) on the minor diameter edge. 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. 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, mechanical properties test) - pre-treatment - for sheet metal cutting-welding-seam UT or RT flaw - annealing treatment - roughing-finishing- vibration de-stressing-hot blasting -finishing
