Detailed description of the invention
As shown in Figure 1, hot press provided by the invention quick fuel feeding load pressurized hydraulic system, working cylinder 4 including the some fluid pressure types being arranged on bottom hot press, working cylinder 4 connects the fuel feeding end for oil cylinder 1 by oil circuit, it is piston supercharged structure for oil cylinder 1, working cylinder 1 is pressurizeed by the hydraulic oil in piston 2 push chamber, piston 2 connects its speed moved of control and rises cylinder 3, speed rises cylinder 3 and is connected to plunger displacement pump 5 between the fuel feeding end of oil cylinder 1, drive speed to rise cylinder 3 by plunger displacement pump 5 piston 2 for oil cylinder 1 is pressurizeed, the floor space supplying oil cylinder 1 rises the floor space sum of cylinder 3 more than working cylinder 4 and speed.When operating, a part of hydraulic oil flows into working cylinder 1, and another part flows into speed liter cylinder 3 and promotes, it is achieved to working cylinder 1 fast lifting.
The travel switch 8 that triggering work cylinder 4 top is arranged when working cylinder 1 rises to a certain degree, it is provided with, between working cylinder 4 and confession oil cylinder 1, the check valve 6 allowing hydraulic oil to flow to working cylinder 4 in certain pressure, being provided with between outfan and the outfan of check valve 6 of plunger displacement pump 5 and control the solenoid directional control valve I (7) that plunger displacement pump 5 pressurizes to working cylinder, the top of working cylinder 4 is provided with and controls the travel switch 8 that solenoid directional control valve I (7) works.The solenoid directional control valve II (9) of the hydraulic oil backflow controlled in working cylinder 4 it is connected between outfan and the confession oil cylinder 1 of check valve 6.
During work, during for in-oil cylinder piston upward sliding, the hydraulic oil in cylinder is released for oil cylinder, flow out hydraulic oil one road for oil cylinder and flow into speed liter cylinder, another road flows into working cylinder, during electric motor starting, the hydraulic oil for oil cylinder is transported in the middle of speed liter cylinder by plunger displacement pump, speed rises after cylinder passes into hydraulic oil and will be pushed up for oil cylinder inner carrier, rises in cylinder and in working cylinder thus being flowed into speed for in-oil cylinder hydraulic oil.Owing to the diameter of speed liter cylinder is less, and the flow to speed liter oil supply cylinder is relatively big, so the rate of climb of fast liter cylinder is than comparatively fast.Speed rises the rapid increase of cylinder and has driven the rapid increase for oil cylinder inner carrier, due to being relatively large in diameter for oil cylinder, the speed risen for oil cylinder inner carrier is consistent with the rate of climb that speed rises cylinder, so the fuel supply flow rate for oil cylinder is bigger, thus the rate of climb of working cylinder is very fast, reach the zooming purpose of hot press.Postpone when working cylinder is climbed to specific bit, triggering travel switch, the electromagnetic valve reversal valve I controlling plunger displacement pump and working cylinder is opened, and is in closure state after arriving certain pressure due to check valve, plunger displacement pump starts to beat high pressure to working cylinder, until stopping after setting pressure.When needs pressure release, solenoid directional control valve II is opened, and the hydraulic oil in working cylinder can pass through solenoid directional control valve II and again flow back into in oil cylinder.
The present invention is only with the motor that a power is smaller, so this hydraulic system is compared to other hydraulic system and can save the cost of manufacturer, the most important thing is to solve the job requirement of quick-make during man-made board hot-pressing machine work, can quickly give working cylinder ftercompction simultaneously, save the working time of hot press, improving the work efficiency of man-made board hot-pressing machine, the hydraulic oil transmission system of Guan Bi can improve the service life of each hydraulic component of hot press.
