1)4 rollers,CNC system 2)the main drive use hydraulic motor 3)two sides pre-bending 4) High efficiency,accuracy
Easy to use Minor diameter can be rolled With pre-bending function High efficiency Hydraulic drive Only one operator needed Fast and accurate 1, summarize: This four rolls bending machine used to coil plate into different shapes such as cylindrical form, conic form and arc, it adopted Japan hydraulic technical. Top roll is main drive rolls, it can do vertical and level motion, up and down, parallel translation is display. This machine include pre-bending function. 2, main technical data: Max thickness of plate 10mm Max length of working rolls 2600mm Max width of plate 2500mm Min diamiter can roll 405mm Up roll diameter: Φ 270mm Down roll diameter: Φ 2500mm± 3 Side roll diameter: Φ 210mm± 3 Bending speed 4m/min Main drive motor 11 KW Max pressure of hydraulic system 19.5Mpa 3, structure and main parts: This equipment composed of work frame, upper roll device, main drive device, down roll device, side roll device, balance device,
tuning device, hydraulic system, electricity control system, NC system, lubricate device. 3-2 the main drive device drive upper rolls do rotary movement. The two sides is support by SP-1 sliding bearing. The drive side through keys, gear and main drive device. The material of upper roll is 42Cr, heat treatment is
HB220-280. 3-3 main drive device Composed of YZR motor, V type triangle belt, three class gear speed reducer, one set open-gear. 3-4 down roll device Down roll is supported by aligning bearings, the bearing based in the rail of two side frames. The down side jointed with cylinder
pistons. The bearing base can move up/down in the rails under hydraulic force. The adjustment of Pistons force controlled
hydraulic system pressure values according to the up/down rolls clamping force. The support rolls were added on the bottom, bending precision will be increased in this way. The material of down rolls is alloy
heat treatment HB220-280. 3-5 side rolls device Side rolls fit on the arc bearing base plate which fix on the two sides frame rails. The down side jointed with cylinder pistons.
The bearing base can move up/down in the rails under hydraulic force. The adjustment of Pistons force controlled hydraulic
system pressure values according to the up/down rolls clamping force. The material of side rolls is alloy heat treatment HB220-280. 3-6 tuning device Composed of RAM, bearing, tuning cylinder 3-7 balance device Composed of balance compact, screw 3-8 lubricate device Main speed reducer and side drive speed reducer adopted oil pool fly lubricate type, it is cooled naturedly. When
environment temperature is -10~0 use N46 and N68, when environment temperature is 0~40 use N150 and N220, the other lubricate points adopted oil
gun to fill manually, working MEDIA is ZGN40-1 grease(winter ) and ZGN40-2 (summer), two times for one shift. 4, hydraulic system Composed of Y series motor, gear pump, valves, oil tank, pipe and so on. Pressure adjusted by overflow valve, system working pressure 0-19 MPa, normal pressure is 19.5Mpa. The valves adopted from Taiwan. 5, electricity system Composed of electrical box, operation table, manual button. The power is 380V50Hz adopted PLC control system code with
longevity easily operate. Whole bending process can read from the indicator setting on the control box.
