Upper  plate rolling machine can do both level movement (move from left to right) and vertical movement (move from up to down).

Bottom roller is fixed. It just does rotation clockwise and counterclockwise.

Pre-bending is achieved by horizontal movement of upper roller and presses the end of plate .High precision pre-bending; freely control the straight side of plate.

Rolling round, it is achieved by means of the motor and reducer to drive two bottom rollers.

The tipping device is very flexible, plate bending machine make the roller plate material can be got off easily.

The support roller improves the precision of rolling process, which can make rolling process more smoothly and perfectly.

The main features of this machine are as follows:

Prominent rolling precision

Unique bending technology, which can control the back angle and straight line efficiently

Man-machine interaction interface, efficient intelligent operation

Physical bending technology software, man-machine interaction window, automatic compensation during the process of bending

Single person operation, efficient and convenient

It can roll the plate material into O type, U type, multistage R and other different type.

Vertical movements of lower and side rollers are driven hydraulically, controlled by microcomputer and
leveled automatically.

LCD display and available for video-data input, edit, calculation, change and store

System protecting function, fault alarm and fault self-diagnosis.

Slim remaining straight edge and high bending precision

Providing the function of microcompwoer opitimizing coil sheet
◇ Less remaining straight edge than our other products. Slim remaining straight edge and high bending precision

Real-time data and coiling signal display, system protecting function, fault alarm and fault self-diagnosis,
wrong operation intelligent judgment, power shutdown memory and safe protection, etc

Most advanced coiling  machine in this industry

This machine structure pattern is three-roll symmetrical expression, the upper roll makes the vertical vibratory movement in two lower roll central symmetry position, it is obtained through the hydraulic cylinder in hydraulic pressure painter??s shop uses in the connecting rod, it is hydraulic transmission; Two lower rolls make the rotary motion, it provides the torque for the bending plate through the speed reducer output gear and the lower roll gear meshing; There are many groups supporting roller under the two lower rolls, they can enhance the rigidity of the lower roll and may carry on the vertical adjustment; there is a rigid beam equipped upside the in upper roll, There are many groups supporting roller between the rigid beam and upper roll to enhance the rigidity of the upper roll; It is suitable in the ultra width round arc components bending.

1) The three roller Plate Rolling Machine adopts three-roller symmetrical structure with the upper roller moving vertically in the centre between the two lower rollers ,which is achieved through the drive of the screw,the nut ,the worm and the lead screw.

2) The two lower rollers rotates ,and provides the plate materials with torque through the engagement of the output gear of the moderator with the gear of the lower rollers.

3) The disadvantage of the bending machine is that the ends of the plate materials need to have the help from other equipment for pre-bending. ]]> http://www.plate-bending-machine.cn/2009/09/4-roller-plate-rolling-machine-2/feed/ 0 http://www.plate-bending-machine.cn/2009/08/plate-rolling-machine-bottom-roller-movement/ http://www.plate-bending-machine.cn/2009/08/plate-rolling-machine-bottom-roller-movement/#comments Tue, 25 Aug 2009 02:06:10 +0000 admin http://www.plate-bending-machine.cn/?p=5 The plate rolling machine–bottom roller movement, its bottomer roller is transportable in the horizontal direction, curls the conic cylinder is extremely convenient, the steel plate end may the discharge head (pre-bend).plate bending machine,plate rolling machine

The upper and the bottom rolls, which work as the main drive at the same time, provide drive by hydraulic motor. They may transfer normal-reversely to provide torque needs.

The bottom roll lifts vertically, clamps bending plate by hydraulic cylinder. It can realize asymmetric bending.

There are side roll on both sides of upper and bottom rolls. The side roll makes arc lift along with axes of bottom roll. When side roll moves upward, the bending plate will be bent and formed, and it moves upward and downward by hydraulic cylinder.

The supporting structure is made of welded steel plate construction (material 345mpa), and treated with annealing after welded to eliminate internal stress.

Characteristics:

(1) The pre-bending length of straight side for bending plate is less than other types of bending machines.

(2) The bending process is much safer and more reliable than other types of bending machines.

(3) For the clamping force to plate between upper roll and bottom roll, the corresponding force can be adjusted by regulating valve in hydraulic station, according to different thickness and width of plates.
