W12 -25*2500 Model Prebending Function 4-Roll roll bending machine from Accurl

Product Application

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, 4 roller rolling machine main drive mechanism,downturn system, left and right machine frame, chassis and balance mechanism, hydraulic and electrical control systems.
3.The model MH has both the upper and the lower roll powered with hydraulic motor and planetary gear box.

The main character of the equipment

1. The machine is computer-controlled four roller bending rolls machine with the pre-bending function. After the plate loaded, no need to change into another side edge for the prebending and rolling.

2. The machine four rollers has been produced by forge, hardening and tempering treatment. HB220-260 with good mechanical properties, high rigidity, high in anti-abrasion, good for high-load working and long working lifetime.

3. Our working roller side gear use ball gear, small in friction and reduce the active power lose and save the energe.

4. The bottom roller and side rollers movement are controlled by computer. Automatic-leveling, digital display screen, the synchronization accuracy ±0.2MM, high in rolling precision and easy in operation.

5. The machine down roller, side roller can do one-side inclining, and can make synchronization movement in inclined position for a better cone rolling working.

6. The machine has moveable operation table for a convenient worker operation and the touch screen has the position for the three rollers, easy for you understand the position.

7. The machine control system adopt Japan OMRON company intelligent PLC programmable control with fault diagnosis and operation fault intelligent judgment, the all parts inspection for the machine, logic treatment , power-off memory.

8. High-voltage parts use SUZHOU electronic, long working lifetime and less fault.

9. The hydraulic valve in the hydraulic system use Taiwan brand, the valve is casting runner , large oil flow ,small resistance, less heat and reliable.

10. The dumping gear will force on the dumping hydro-cylinder, the head can incline and stand-up, convenient for take-off the working pieces.

Hydraulic system

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.

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

Application of 3-roller and 4-roller plate bending machine,plate rolling machine,plate roller

3 Rollers and 4 rollers rolling machine,as the shaping equipment for bending,rolling,leveling of metal plate,are widely used in the industries of shipbuilding ,boiler,airspace,water and electricity ,decoration and metal structure,and the features complete specifications,multiple types,well-designed structure,and and advanced techniques to meet customer’ requirements.
