Rolling Machine

Rolling Machine, W11s

Descriptions of Rolling Machine, W11s :
The machine tool can be used to make the steel plate into barrel shape, circular shape and conical shape etc.
1. The upper roller of the metal machining machine can move vertically as well as horizontally;
2. The plate bending machine can finish the pre-bending work and coiling work at the same machine.
3. Drum-type design upper roller: so the metal machining machine has the anti-deformation function.
4. Support rollers are equipped under the lower rollers: so it can help to coil products with high precision.
5. The lower rollers are fixed symmetrically and they are driven by mechanical drive.
6. Upper roller ascends or descends at the central symmetric location of the lower rollers; the ascending and descending are hydraulic driven.
7. Upper roller of the metal bending machine moves to the left or right position to prepare for pre-bending work. The limited switches control the shift position.
8. PLC control is adopted to control the upper roller and LCD display is employed for displacement in the metal machining machine.
9. Hydraulic drive is employed for dumping and resetting of the reverse head unit.
10. The control system of the Rolling Machine is movable: so you can operate the machine tool at any position.

Main Structure of Rolling Machine, W11s :
The Rolling Machine composed of upper rollers, lower rollers and horizontally move device, support roller device, main drive device, reversal device, right and left side frame and bottom plate.
1. Upper rollers device:
Upper device composed of main cylinder, upper bearing base, upper roller, double central adjust bearing.
Upper roller material: 42CrMo;
Hardness: HB 240-280;
Surface: IF quenching HRC45-50.

2. Lower rollers and level movement device:
Lower roller device composed of lower rollers, lower roller bearing base, lower input gear, and lower roller sliding bearing.
Main drive supplies the main power through output gear, down roller input gear, opening drive torque to lower rollers.
Lower roller material: 45#;
Hardness: HB240-280;
Surface: IF quenching HRC45-50.

3. Level movement device:
Level movement device composed of level movement motor, worm wheel worm pole box; worm wheel worm pole.
Level movement device is driven by motor. Through worm wheel worm pole box, screw pole can move in horizontal and bending in symmetry.

4. Support device:
Composed of screw pole device, leaning device and support rollers;
The support device can be adjusted upward or downward according to different coil plate speciation.
Support roller material: 45#;

5. Main drive device:
It's composed of main motor, belt, gear reducer box, electricity and hydraulic drive device.

6. Reversal devices:
It's composed of sliding pillow and reversal cylinder.

7. Balance devices:
It's composed of balance press block and screw.

Hydraulic System of Rolling Machine, W11s :
It's composed of gear pump, valve group, and pipes. The system is composed by pressure adjusting circuit, synchrony circuit and speed circuit.
The pressure adjusting circuit adjusts the working pressure through the overflow valve;
The max. pressure is 19.5Mpa;
The synchrony circuit separates roughly the hydraulic oil to the ascending and descending of the upper roller through the by-pass valve;
The restrictor valve adjust the upper roller ascending and descending;
The displacement transducer detect the displacement; the synchronization precision is ±0.15 mm;
The speed circuit control the dumping and resetting of the reverse device through adjusting the restricting speed by restrictor valve.

Electricity System of Rolling Machine, W11s :
(1) General summary
Electric control system consists of controlling table, hand button box.
Motivate power of the metal machining machine is three-phase four lines 380V/50Hz.
PLC programming control system is adopted;
The Rolling Machine's working status can be controlled through the control box;
Touching screen display and operation: so the plate or metal bending machine is easy to operate and all parameters are clearly displayed.
(2) Protections
All motors have equipped with breakers and heat relays to protect against short circuit or overload etc.
Corresponding limit location switch are equipped as terminal protection for the horizontal moving of the upper roller, ascending and descending of the supporting roller.
Upper and lower limit switch are set respectively for the reverse of the reversal crock and reposition.
The main power switch has shunt release, and both the working table and the bracket have "emergent stop" button.

All Kinds of Interlock of the Plate & Metal Bending Machine:
(1) After the reversal frame completely repositioned, all the actions can proceed (take the "reversal frame reposition" limit location switch as the examination);
(2) When the upper roller is on the upper location, the horizontal moving of upper roller and the independent descending of reversal side cannot proceed ("upper roller up position" limit location switch as examination);
(3) When the working pressure of the upper roller pressure relay is over 1/3P, the upper roller and the support roller cannot move. (Pressure relay as examination)

Failure Directions of the Metal Machining Machine:
(1) When the lower roller motor, horizontal moving motor and support roller motor is over-load, the failure direction light gives direction.
(2) When there is wrong with the PLC, the failure direction light gives direction.

Technical Features of the Rolling Machine:
Drum-type upper roller, the lower part of the lower roller and the support roller are in coordinate with the adjustment as well as the products' line degree with high precision.
(1) Drum-type upper roller is adopted, and the pre-settled amount of the drum-type is generally 70% of the average load of the rollers.
(2) The lower roller with smaller diameter is supported by support roller which can be adjusted up and down.
(3) According to the load of the roll-bending goods, adjust the support roller beneath the lower roller, which greatly improve the line degree of the products.

Backside Bending Function of the Rolling Machine:
This metal machining machine adopts backside bending (the direction of material delivery and the upper roller moving is opposite): once the upper roller presses down, the lower rollers circumgyrate and the machine will continue to bend.
The ends of the plate are directly pre-bending, which avoid the back angle caused by front bending and it also can control the width and the shape of the rest ends.
