Description
Technical field:
The present invention relates to a kind of threaded cartridge valve hydraulic control system, the equipment of particularly little tonnage threaded cartridge valve hydraulic control system.
Background technique:
At present, the main sliding valve style hydraulic control system that adopts the development fifties in the little tonnage hydraulic press system, its guiding valve hydraulic control system performance parameter is low, complex structure, the rate of fault height leaks seriously, and it is unreliable to move, fast speed is unadjustable down, and it is bigger to take up room, and maintenance is inconvenient.
Summary of the invention:
Purpose of the present invention, provide a kind of threaded cartridge valve hydraulic control system, it is to adopt threaded cartridge valve to combine with the integrated hydraulic control system, controls the control system of little tonnage hydraulic press, solves complex structure, the rate of fault height, leak seriously, it is unreliable to move, and descends speed unadjustable soon, it is bigger to take up room, the problem that maintenance is inconvenient.
Threaded cartridge valve hydraulic control system of the present invention takes following technological scheme to realize: it is by three position four-way electromagnetic valve, cartridge valve, relief valve, sutaining valve, one-way valve, one-way throttle valve is integrated, filler opening and two three position four-way electromagnetic valves, the plug-in mounting pressure valve, pressure gauge is communicated with, return opening and two plug-in mounting pressure valve, two relief valves, three three position four-way electromagnetic valves, safety valve is communicated with, three position four-way electromagnetic valve is communicated with one-way valve and pressure relay, three position four-way electromagnetic valve and electromagnet cut off valve, sutaining valve and liquid-filling valve are communicated with, one-way valve is communicated with pressure gauge and main oil cylinder piston chamber, electromagnet cut off valve is communicated with one-way throttle valve, one-way throttle valve and sutaining valve, safety valve and master cylinder bar chamber are communicated with, two relief valves, relief valve and plug-in mounting pressure valve are communicated with three position four-way electromagnetic valve, three position four-way electromagnetic valve with eject the cylinder rod chamber and be communicated with, three position four-way electromagnetic valve is communicated with one-way valve and one-way valve, one-way valve and relief valve, plug-in mounting pressure valve and outer control mouthful are communicated with, one-way valve with eject oil cylinder plug chamber, pressure gauge and plug-in mounting pressure valve are communicated with.Two three position four-way electromagnetic valves are plate valve, and all the other control valves are screw-in cartridge valve or two-way plug-in valve.With the system pressure adjusted design is modular type, and ratio regulatory function, electromagnetism relief function, telecontrol and safety protection function are provided.
Threaded cartridge valve hydraulic control system of the present invention is realized hydraulic press fast down, compacting, pressurize, release, eject and return the reliable operation of six operations.Hydraulic press is not provided with and ejects oil cylinder, then realize hydraulic press fast down, the reliable operation of compacting, pressurize, four operations of release.
The working principle of threaded cartridge valve hydraulic control system of the present invention is as follows:
Fast operation down, electromagnet YV1, electromagnet YV3, electromagnet YV5 energising, the plug-in mounting pressure valve is closed, and this moment, the system pressure valve was a high pressure, make that system pressure oil can not oil return, system pressure oil enters oil cylinder plug chamber by one-way valve, because speed is fast under fast, and system's oil-feed deficiency, oil cylinder plug chamber forms negative pressure, liquid-filling valve is opened by self-priming, and fluid enters the chamber repairing of oil cylinder plug by liquid-filling valve, and the fluid in cylinder rod chamber is by one-way throttle valve, electromagnet cut off valve, three position four-way electromagnetic valve oil return.
Suppression process, electromagnet YV1, electromagnet YV3 energising, the plug-in mounting pressure valve is closed, this moment, the system pressure valve was a high pressure, made that system pressure oil can not oil return, because electromagnet YV5 closes, relief valve and the three position four-way electromagnetic valve oil return of the pressure oil in cylinder rod chamber by transferring to certain pressure forms certain resistance, so pressing speed is slack-off, the realization full gear is descending, system's oil-feed is enough, and liquid-filling valve cuts out, behind contact workpiece, system boosts, and realizes suppression process.
The pressurize operation is a pressure when reaching requiring of working pressure, and the pressure relay sender makes electromagnet outages all in the whole system, enters packing state, mainly comes pressurize by one-way valve in the system.
The release operation, be after pressurize is finished, by the time delay relay sender, electromagnet YV2 and electromagnet YV4 energising, the plug-in mounting pressure valve is closed, this moment, the system pressure valve was a low pressure, made that system pressure oil can not oil return, and system pressure oil enters liquid-filling valve control mouthful by three position four-way electromagnetic valve, liquid-filling valve is realized pre-pressure release power earlier, and then open, system pressure oil enters the cylinder rod chamber by electromagnet cut off valve and one-way throttle valve simultaneously, makes the oil cylinder backhaul.
Eject operation, electromagnet YV1, electromagnet YV6 energising, the plug-in mounting pressure valve is closed, this moment, the system pressure valve was a high pressure, made that system pressure oil can not oil return, and system pressure oil enters by three position four-way electromagnetic valve and one-way valve and ejects oil cylinder plug chamber, system pressure oil is sealed one-way valve simultaneously, make the plug-in mounting pressure valve close, the fluid that ejects the cylinder rod chamber realizes ejecting operation by the three position four-way electromagnetic valve oil return.
Return operation, electromagnet YV1, electromagnet YV7 energising, the plug-in mounting pressure valve is closed, and this moment, the system pressure valve was a high pressure, made that system pressure oil can not oil return, and system pressure oil enters by three position four-way electromagnetic valve and ejects the cylinder rod chamber, realizes returning operation.
The effect of threaded cartridge valve hydraulic control system of the present invention is simple in structure, adopt threaded cartridge valve, the external form volume is little, operation control is accurately easy, and working stability is reliable, does not have and reveals, have high efficiency and energy efficient, reduce equipment manufacturing cost, the level of integration height is widely used on 40～200 tons the hydraulic press equipment.
