Abstract
The utility model discloses a hydraulic system of a die-forging quick hydraulic lifting device, the hydraulic system comprises a lifting feed hydraulic cylinder (7), a two-position four-way electromagnetic reversing valve (6), a hydraulic pump (3) and a hydraulic oil tank (1), wherein the hydraulic oil tank (1) is communicated with an oil inlet cavity of the lifting feed hydraulic cylinder (7) through an oil outlet pipe, the hydraulic pump (3) and the two-position four-way electromagnetic reversing valve (6) are connected on the oil outlet pipe, and an oil outlet cavity of the lifting feed hydraulic cylinder (7) is communicated with the hydraulic oil tank (1) through the two-position four-way electromagnetic reversing valve (6) through an oil return pipe. In the hydraulic system of a die-forging quick hydraulic lifting device, the quick discharge can be realized through the assistance of the hydraulic system, the time of a hot die-forged piece in a die can be reduced, and the working efficiency can be improved.
Description
Technical field
The utility model relates to hydraulic system, has to relate to the hydraulic system of carrying out the die forging fast hydraulic pressure Lifting Device of inloading part after forging part is shaped, and belongs to the former technical field.
Background technology
As everyone knows, adopt Lifting Device that the forging part after being shaped is carried out inloading part, at present at home, forging equipment generally all is just to carry out demoulding discharging by mechanical transmission mechanism in the stroke work that makes progress when stopping, and this moment, the dump energy or the strength of equipment were very little, causes generally difficulty relatively of hot-die forging depanning, usually can not a discharging success, cause die life short, labor strength is big, inefficiency.
Summary of the invention
The purpose of this utility model is: a kind of hydraulic system of die forging fast hydraulic pressure Lifting Device is provided, by the auxiliary realization quickly discharging of this hydraulic system, reduces the hot-die time of forging in mould, increase work efficiency.
Technical solution of the present utility model is: this hydraulic system comprises liftout fluid cylinder, two-position four-way solenoid directional control valve, hydraulic pump and hydraulic oil container, hydraulic oil container is communicated with the oil suction chamber of liftout fluid cylinder through flowline, connect hydraulic pump and two-position four-way solenoid directional control valve on the flowline, the oil pocket that goes out of liftout fluid cylinder is communicated with hydraulic oil container by oil return pipe through the two-position four-way solenoid directional control valve.
Wherein, the flowline of hydraulic oil container connects the solenoid directional control valve of hydraulic pump and two-position four-way again through the oil-feed filter.
Wherein, be connected oil storage accumulator and overflow valve on the flowline between hydraulic pump and the two-position four-way solenoid directional control valve, overflow valve is communicated with hydraulic oil container.
The utlity model has following advantage: 1, Lifting Device is made up of hydraulic system connection material jacking mechanism, effectively realizes bigger liftout strength making work faster; 2, simple and reasonable, can realize that forging part is shaped the back to carry out discharging than big ejecting force, help increasing work efficiency, the better protection mould has stronger practicality; 3, whole Lifting Device existing air-driven have again fast hydraulicdriven steadily, low noise; 4, Lifting Device required input power is little, and liftout demoulding strength is big, and work is quick, good economy performance; 5, realize the fast demoulding discharging, the time of contact of forging and mould is short, and the life-span of mould is long; 6, liftout demoulding strength is big, can reduce the pattern draft of forging, makes the stock utilization height of forging; 7, in hydraulic system, designed the oil storage accumulator, the work of die forging liftout is one and is interrupted the work that repeats, accumulator has been arranged, and pressure when making liftout in the hydraulic system and fuel supply flow rate no longer are substantially invariable values, but the value of a fluctuation, in the time of can accomplishing that pressure is big in the fluid cylinder, fuel supply flow rate reduces, pressure hour, and fuel supply flow rate increases, enough strength is arranged in the time of so both can guaranteeing the liftout demoulding, can guarantee that again the stroke after the demoulding is quick.
