automatic plate rolling machine

Instruction of the main technical parameters:
3.1 The maximum capacity of plate rolling machine was decided by the maximum rolling thickness, maximum rolling width, material of plate and minimum rolling diameter when bending maximum specification of plate. The conversion relationship between these four parameter variables, namely conversion relationship of machine rolling capacity, we provide these parameters in user instruction so that user could use the plate bending machine more reasonable.

3.2  The plate rolling machine can roll conical work piece. When rolling conical work piece, the force of single end is large, therefore only 60% of the machine ability could roll cone, usually, conical work piece is not more than 30 degree, but with decreasing plate width and thickness, the machine loading capacity was reduced, degree of cone could be increased.

4. The main characteristics of the cnc automatic plate bending machine

4.01 the plate rolling machine  is computer controlled lower roller bending machine.

 Through displace of lower roller, upper roller and lower roller are in non-symmetric state, then machine could pre-bending the end of sheet. Machine could pre-bend and bend to round cylinder once plate come into machine, do not need u-turn.

4.02  three working rollers adopts forging steel 42CrMo, after forging, quenching and tempering, HB270, good mechanical properties, high strength, strong wear resistance, suitable for high load operation, long service life.

4.03 all three rollers of machine are driving roller. advantage is: firstly it does not slip when bending thin sheet, the machine with three driving rollers is better than machine with upper driving roller or with lower driving roller, its main load-bearing part are connected by keys and pins, convenient installation and repair.

4.04 Both ends of working roller adopt double row self-aligning roller bearings, large carrying capacity, and reduce the friction power loss, long service life, energy saving. Due to the adoption of self-aligning roller bearing, the tilt adjustment of roller is very convenient.

4.05 The rotary action of three working rollers are equipped with a braking device, to ensure accurate positioning of the workpiece, safe and reliable operation.

4.06. Horizontal movement of lower roller and lifting movement of upper roller were controlled by computer, automatic leveling, screen digital display, the synchronization accuracy of ± 0.2mm, high precision of rolling, convenient operation.

4.07.the upper roller could be single end tilt, convenient bending conical workpiece.  The upper roller was designed like a drum, 70% of maximum rolling pressure force of the upper roller as uniform load to compensate the deflection.

Large diameter of lower roller, has enough rigidity and strength, so it does not need to add the carrying roller device, also can reduce the equipment failure rate, upper and lower roller stiffness are in line with the requirements of L (1/700-1/1000).

4.08. The frame of machine adopts welded structure, meet requirement of JB/T 5000 or JB/T1829-1997, after welding, furnace annealing to remove stress, mechanical processing, shot peening. The whole machine has sufficient strength and rigidity.

4.09 both ends hydraulic cylinder of upper roller were put at the bottom of machine, hydraulic cylinder and machine base constitute the whole machine.  This structure lowered the center of gravity of machine, more stable, there is no chattering phenomenon caused by high center of gravity when bending plate, the bending force were put on the whole machine base, machine rack  bear only  torsion of bending plate.   Turnover bearing body move flexibly and quickly when unload workpiece. Stability of equipment is very important for large equipment.
4.10 The plate rolling machine are equipped with a movable operation platform, more convenient operation, touch screen display the position of the three rollers, enables the operator to stick out a mile

4.11. The  plate rolling machine  control system adopts the Japanese company OMRON PLC programmable controller, the system has function of parameter setting, data editing, sound alarm, power-off memory, man-machine interface, status display, real-time computing, storage file, debug mode, manual mode, Programmed mode, document editing, fault self diagnosis, operation fault intelligent identification; the system has strong anti-interference capability, long service life, strong anti-seismic, stable operation

4.12. regarding returning position of two lower rollers, the computer has an automatic centering function, ensuring the symmetry of the two lower rollers and upper roller when rolling plate, greatly facilitate the worker's operation.

4.13. the movement of upper roller and lower rollers adopt high precision sensors, in order to ensure the position precision and realize the roller position monitoring

4.14. the main electrical components select good products of famous domestic manufacturer, with long service life, long time before fault.

4.15. main valves of hydraulic system adopt the northern Taiwan Seiki products. These valves are  casting passage, large discharge, small resistance, small pressure loss, low fever, make the machine  performance more reliable.

4.16. Hydraulic pipe joint adopts cone sealing fast joint, the joint is reliable radial sealing, to ensure that the hydraulic system of equipment does not leak oil.

4.17. The hydraulic system have filter for absorbing and returning oil, to ensure system clean; have air cleaner, to keep normal breath of oil tank and the evaporation of moisture; have dual channel of safety protection device, to ensure the use safety.

4.18. The turnover bearing body(unloading bearing) were driven by hydraulic cylinder, could be taken down and stood, that is convenient to unload workpiece after rolling. There are a safety interlocking device for turning and resetting the unloading bearing body. After the unloading bearing body turning, other action of machine are in standby state, recovery normal movement only after the turnover bearing body resetting, thereby interlocking device playing the role of safety protection.

4.19. the upper roller tail were set balancing device, the balancing device balance the upper roller when the turnover bearing body being turned over and workpiece being unloaded, that is very convenient to unload the round workpiece.

4.20. the cnc automatic plate rolling machine adopt the integral base, strong rigidity, easy to hoist , easy to install. Machine racks and base adopt the welded structure that were annealed aging treatment and eliminated internal stress, improving the precision of rolling. The whole machine structure like modular organization, beautiful appearance, more convenient to repair.

4.21. the cnc automatic plate rolling machine  are equipped with conical shape rolling device, could roll equipment parts in a certain degree scope.

4.22. the cnc automatic plate rolling machine  equipped with a centralized lubrication system.  

4.23. the due to the center of lower rollers is unchanged, that is convenient loading plate into machine and operation.
