The work step of above structure is:
1, start oil pump 21.
2, hydraulic oil by manual 28 pressure regulation of overflow valve be successively input into the first hydralic pressure gauge 23, proportional pressure-reducing valve 24, using
The control of solenoid valve 29 enters the cavity of resorption 42 of oil cylinder 4, and the pinch roller 19 that oil cylinder 4 is controlled at this time is fallback state.
3, when starting slot rolling Machining Instruction, hydraulic oil is successively input into the first hydralic pressure gauge by manual 28 pressure regulation of overflow valve
23, proportional pressure-reducing valve 24, hydraulic oil enter the epicoele 41 of oil cylinder 4 through the control of solenoid valve 29, and oil cylinder 4 pushes pinch roller 19 close to pipe fitting
W。
4, when the second hydralic pressure gauge 26 incude it is hydraulic reach preset pressure when (i.e. pinch roller 19 has touched pipe fitting W), pass through
PLC changes 24 pressure of proportional pressure-reducing valve and the flow of proportional flow control valve 25 carries out slot rolling.
5, when slot rolling terminates (i.e. aforementioned magnetic railings ruler structure informs that PLC has reached default slot rolling depth), the control of pinch roller 19 exists
Original position cannot retreat, it is necessary to control solenoid valve 29 for hydraulic oil by operator's (or clicking manually by touch screen) control PLC
The cavity of resorption 42 of oil cylinder 4 is imported, the pinch roller 19 that oil cylinder 4 is controlled at this time is fallback state and unclamps pipe fitting W.
As described above, the essential of exercise of oil cylinder is in the utility model: unloaded oil cylinder F.F., loading cylinders slow-motion, slot rolling
End oil cylinder is parked in original position and does not move back, manual rewind oil cylinder.Unloaded oil cylinder F.F., it is therefore an objective to improve production efficiency, loading cylinders are slow
Into, it is therefore an objective to improve slot rolling quality.When pinch roller 19 contacts pipe fitting W, pressure to preset value sensor sender is to PLC, and PLC is new
Pressure flow instruction issue proportional flow control valve 8, proportional pressure-reducing valve, oil cylinder is worked with setting pressure and stability of flow.
Proportional flow control valve, ratio are used in the hydraulic fluid flow rate and pressure control mechanism of the pipe fitting channelling machine of the utility model
Example pressure reducing valve, i.e. electro-hydraulic proportional valve.The advantage is that: when equipment mechanism require during the work time the pressure to hydraulic system,
Flow parameter is adjusted or continuous control (such as: it is required that workbench is in work feed by the speed of slow, fast, slow consecutive variations
Degree realizes feeding, or realizes pressure control by some optimal control curve of certain precision analog), Normal hydraulic valve is then realized not
?.At this moment hydraulic system can be controlled with electro-hydraulic proportional valve.
Please refer to Figure 12, in order to cooperate the utility model pipe fitting channelling machine hydraulic fluid flow rate and pressure control mechanism,
