Horizontal stroke of Ungerer high speed is cut measure round of hydraulic pressure loop to transform a paper

2+1 document label piles up: If B pursues 1, in Wu Gang finishing of cold rolling factory cuts line to go up, direction of arrowhead of strip steel edge moves, measure annulus rely on hydraulic pressure oil cylinder surface of clingy strip steel, rotate because of attrition force, offer place accurately to need to cut the length of strip steel through pulse generator. Strip steel is measured annulus rise, drop, stop to wait the movement shows hydraulic pressure loop 2 times to finish by the graph. If the watch is shown 1 times,strip steel measures the working situation of round of oil cylinder, cut a line to wear belt or A of the electro-magnet when throwing tail to get report, oil cylinder rises, measure annulus do not work. Wear belt end, electro-magnet B gets report, oil cylinder drops, measure annulus press strip steel closely. In drop after the movement ends, electro-magnet A and B break phone. Double fluid accuses one-way a powerful person to lock up oil cylinder working surely locally, measure annulus begin computation. The pressure offerring oil of hydraulic pressure loop is 6MPa (concentration offers oil) , through pressure-relief valve 4 adjust pressure to 0.

05~0.

1MPa. Nextpage one, the problem oil cylinder of existence is passed measuring round of power that transfers armor plate to go up is very small, make an appointment with 130N only, so small force, do not spend to thickening originally for 0.

The strip steel of 5mm above is out of shape and produce impress, but fact however often such. Pass the analysis of pair of hydraulic pressure loop, think to drop when oil cylinder, after measuring wheel load to be on strip steel, electro-magnet A and B break phone, oil cylinder position accuses one-way a powerful person to be locked up dead by fluid, two fluid accuse one-way a powerful person to be formed to the two antrum of oil cylinder close cubage; The pressure of piston antrum is as equal as the pressure that offer oil, for 0.

1MPa, lever antrum lateral pressure is equal to the pressure that answer oil. Cut after beginning, strip steel produces vibration in cutting a course (strip steel is thicker vibration is bigger) , oscillatory force is passed measure round of piston speech that delivers oil cylinder inside. Be accused by fluid pressure of antrum of piston of oil cylinder of postmortem of lock of one-way a powerful person is scattered at load, consequently force of bigger pitch internal pressure jumps over vibration big (pressure of antrum of piston of oil cylinder of the actual measurement when vibration is 0.

3~0.

5MPa) , also jump over through measuring the counterforce of wheel pair strip steel big, make strip steel surface appears then impress. Watch 1 2, after transforming measure to analyse hydraulic pressure return, think to have the following problems: (The hydraulic pressure that 1) regards the job as medium is oily from theoretic saying is incompressible, the tigidity of loop of reason hydraulic pressure is bigger, flexible poorer, absorbing the pressure that generates by vibration to pound a respect far not as good as pneumatic loop; (The actuating pressure of system of 2) hydraulic pressure is 6MPa, after passing decompression, be 0.

1~0.

2MPa. Because decompression is poor the value is great, cause low pressure to be not stabilized; (After 3) fluid accuses one-way a powerful person to be locked up dead, pressure follows oscillatory change and change, and pressure is great, press closely, make strip steel and measure annulus synchronous precision is affected, as a result affects the precision that cuts length. For comb-out impress, we loop of pneumatic of instead of hydraulic pressure loop, if pursue,3 are shown. Compress air to have good compression function, can absorb the pressure that generates by vibration to pound. At the same time normal actuating pressure is in pneumatic system 0.

6MPa is the following, adjust even 0.

1MPa still can maintain pressure stability below. Above place of hydraulic pressure system does not have these advantages. Reason thin plate can suit already after loop and do not produce impress by pneumatic of instead of hydraulic pressure loop, also can suit thick board oscillatory and do not produce length error. Consider working atmospheric pressure is inferior, it is about 0.

1MPa, and distance of air cylinder job is shorter, only 50mm, reason does not need throttle to adjust air cylinder rate. Additional, the main effect that uses pneumatic cell is: (1) assures to enrage the cleanness of the source: (2) makes sure the pressure of gas source is stable; (3) makes sure each component has good lubricant requirement. And with pressure-relief valve 2 those who will assure actuating pressure is accurate. If the working signal of pneumatic electromagnetism reversal valve is expressed 2, intermediate position is protected with Yu Wei and overhaul. Watch 2 3, after effect strip steel measures return of round of pneumatic of instead of hydraulic pressure loop, try move more than one year, have the following advantages. 1. Comb-out impress, improved quality of strip steel product, solved a problem that will exist for years; 2. Improved work efficiency; 3. As a result of instead pneumatic loop, hydraulic pressure is used up oilily did not have, equipment safeguards a quantity to be reduced subsequently; 4. Spare parts charge is reduced accordingly.
