It is a half-hydraulic 3-roller symmetrical rolling machine. It is used
at room temperature, with this machine you can bending various profiles
into some types. It can roll profile of cycle, spiral. Changing the modle,
it can bend and roll angle steel, flat steel, square steel, channel,
steel, circle steel, pipe and so on. The machine is compact structure,
reliable work, small volume, full functions, it is economical and practicl.
The machine is the most advanced profile molding equipment at home and
aborad. It is used in oil, chemical, producing ship, water and
electricity, metal structure ,machinery and manufacturing and so on.

Working princinple and structure characteristics
It is a half-hydraulic machine, the upper roller achieve rise and fall movement through down pressure oil tank, the rotating of the two main section is composed of the bed, the lower-roller, the support roller, the transmission ,the electrical ,the hydraulic, muld and so on.
3.1 the frame section
It is achieved by steel plate whole welding, making the whole machine take full strength and stiffness through removing stress dealing ,it can be satisfied with the bending of various profiles in the rang of machine ability.
3.2 the upper roller section
It is composed of the upper roller axis, the connection plate, the slide block, gland and so on. The upper roller is following axis, make upper roller rise and fall pressing workpiece, material come into being plastic deformation, finishing the bending of profile through the action of hydraulic oil tank.
3.3 the lower roller section
It is composed of the lower roller axis, bear, double row bearings tune and gland. The two lower roller is active axis, abtaining by the output bear of the reducer taking the gear of the lower rollers, it is also the active power.
3.4 the transmission section
The two lower rollers is active roller, the upper roller is following roller, it consists of first section belt tansmission, second section reducer transmission, third section bear transmission, making lower roller do positive and negative movement. Through friction producing by mold and profile to drive the upper mold, finishing the work of bending and rolling workpiece.
3.5 hydraulic systerm
The rising and falling of upper roller is finishing by hydraulic systerm, rated working pressure is 19.5MPa.
The systerm adopted bear pump,the rising and falling of oil tank is controlled by the components such as electromagnetic valve, overflow valve and electromagnetic relief valve,doing empty load start,down pressure adjustment,over load unloading before turning on the machine,observating adjusting range of systerm and pressure fluctuations situation through seismic pressure.
Systerm is form of button control,get electrical situation of electromagnetic valve decide the working situation of executing agency(rising and falling of oil tank),by hydraulic control single valve carrying out pretecting pressure opposing to executing components.The
systerm working media is 46# anti-mill hydraulic oil,filled oil must be chear,no-impurities.Before turning on the machine must notice that the rotating of motor is as same as the mark,the maintenance of hydraulic systerm is carried out as for relevant stipulate.
3.6 electrical control systerm
It adopts exchange electrical power by 3-shape 380V 50HZ
providing electricity control circuit, changing 380V for 220V through control transformer providing electricity, electric operation control and illustrate are uniformly putting on the electrical control cabinet,every operating control is showing by figurative symbols,and fitting with movable operation console.
The control systerm is composed by OMRON programmable logic controller, MT506 colour touch display, incremental grating or encolder and low pressure components, MT506 colour touch display connects with PLC through special communications,the main function is adjusting state illustrate touch,and controlling with the coordinating by the function of operator plate button.
The function of operator plate button:
1),SBO: urgent stop button(red mushroom shape)
2),SB1: coordinating use by rising button and display touch key
3),SB2: coordinating use by falling button and display touch key
4),SB3: oil pump starting
5),SB4: lower roller rotating on the left
6),SB5: lower roller rotating on the right
7),SB6: lower roller stoping
8),SAO: left and right rotating point of lower roller moving ,linkage selection
