1. Performance
This four rolls bending machine used to coil plate into different sharps such as cylindrical form, conic form and arc, it adopted Japan hydraulic technical.
Top roll is main drive rolls, it can does vertical and level motion, up and down, parallel translation is display. This machine include pre-bending function.
2. Structure
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.
A. Work frame composed of based plate, fixed side frame and tuning frame, all parts steel-welded. Two side frames fixed on the based plate by screw, and jointed together by beams. The two side frames equip with upper roll and down roll moving rails, the fix one have upper roll and down roll bearing housings.
B. 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.
C. Main drive device
Composed of YZR motor, V type triangle belt, three class gear speed reducer, one set open-gear.
D. 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 head treatment HB220-280.
E. 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 head treatment HB220-280.
F. Tuning device
Composed of ram, bearing, tuning cylinder
G. Balance device
Composed of balance compact, screw
H. Lubricate device
Main speed reducer and side drive speed reducer adopted oil pool fly lubricate type, it is cooled naturedly. When environment temperature is -10~0º C use N46 and N68, when environment temperature is 0~40º C 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.
