8),SAO: left and right rotating point of lower roller moving ,linkage selection

7),SB6: lower roller stoping

6),SB5: lower roller rotating on the right

5),SB4: lower roller rotating on the left

4),SB3: oil pump starting

3),SB2: coordinating use by falling button and display touch key

2),SB1: coordinating use by rising button and display touch key

1),SBO: urgent stop button(red mushroom shape)

   The function of operator plate button:

  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.

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.

  It adopts exchange electrical power by 3-shape 380V 50HZ

3.6 electrical control systerm

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.

  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

  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.

  The rising and falling of upper roller is finishing by hydraulic systerm, rated working pressure is 19.5MPa.

3.5 hydraulic systerm

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.

3.4 the transmission 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.

3.3 the lower 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.

 3.2 the upper roller 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.

3.1 the frame section

  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.
