4 Roller Hydraulic Universal Plate Rolling Machine Hydraulic

Universal Plate Rolling Machine
Summarize:
This machine used to coil plate into different sharps such as cylindrical form, conic form and arc, it adopted Japan hydraulic technical. Top roll can do vertical and level motion, up and down, parallel translation is display.
Feature:
1. The upper roller can move vertically as well as horizontally .
 2. The end pre-bending is finished with high precision by moving the upper roller and making it unsymmetrical position with two lower rollers.
 3. Two lower rollers are driven by the motor and decelerator for rolling the plate.
4. It is convenient and safe for feeding and operating because of the constant altitude of the lower rolls.
5. It is controlled by PLC, and the positioning of the rolls is digital readout.
6. The upper roller is in the shape of drum, accompany of the support rolls of two lower rollers for up and down adjustment, it can get the high precision for deviation from straightness of the finished products.
7. It adopts the rear rolling to gain the high precision for the circularity of the finished products.
8. The feeding direction and the moving direction of the top roll are opposite.
9. The upper roller press down, meanwhile the lower rollers rotate for the continuous bending. 
10. The end pre-bending is accomplished by the direct pressure from the upper roller so as to avoid the “angle of relief” of bending, at the same time; it can control the length and shape of the flat end. 
11. This kind of Plate Rolls Bending Machine also can roll cone shape which is optional.

1.The Feature of Hydraulic plate bending rolls:

1. The machine widely used in petroleum, chemical industry, cement, boiler, shipbuilding, aviation, water conservancy, 
power transmission towers and other machinery and equipment. Its working principle is rotating bending deformation. 
For the upper roller can be moved no matter up and down, but also horizontally, so no need additional press or 
equipment, can realize prebending, bending, as well as correction of the workpiece.

2.The whole structure of Hydraulic plate bending rolls:

  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 MH has both the upper and the lower roll powered with hydraulic motor and planetary gear box.

3.The Feature of Hydraulic  plate bending rolls:

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, AccurL 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 (bullnosing) on the minor diameter edge.
