Technical field
The utility model relates to the foundry machinery field, particularly a kind of template rotary fluid pressure device.
Background technique
The power of template rotating machinery provides by hydraulic system in the existing foundry production line, and this hydraulic system is made of motor, pump, solenoid valve and oil hydraulic cylinder, rely on hydraulic cylinder piston rod stretch out or the driving template of withdraw is finished 180 ° of spinning movements.Hydraulic cylinder piston rod in the existing hydraulic control structure stretch out and the pressure oil of all being exported by pump of withdraw is exerted pressure, its piston rod stretch out or retraction speed slow, if realize stretching out fast of hydraulic cylinder piston rod, must strengthen the flow of pump, therefore need to select large discharge pump, need to be equipped with the solenoid valve of powerful motor and big latus rectum simultaneously, cause the raising of equipment cost.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of scientific structure design ingenious, can improve that hydraulic cylinder piston rod stretches out and retraction speed, thereby realizes the atwirl template rotary fluid pressure device of template.
The utility model solves its technical problem and takes following technological scheme to realize:
This template rotary fluid pressure device, constitute by motor, oil pump, solenoid valve and oil hydraulic cylinder, it is characterized in that: described oil pump oil outlet is connected with the oil hydraulic cylinder rod chamber by pipeline road, be provided with first solenoid valve between oil pump and the oil hydraulic cylinder, the oil hydraulic cylinder rodless cavity is connected with a gas holder by gas piping, is filled with compressed inert in oil hydraulic cylinder rodless cavity and gas holder.
And described inert gas is nitrogen or helium.
And the pipeline road between described first solenoid valve and the oil hydraulic cylinder is provided with second solenoid valve, and the P-T mouth of this second solenoid valve links to each other becomes total filler opening, and the A-B mouth links to each other becomes total oil outlet.
And the pipeline road between the described oil pump and first solenoid valve is provided with electromagnetic relief valve.
And the suction port of described gas holder is connected with an inflator.
Advantage of the present utility model and good effect are:
1. the process of stretching out of hydraulic cylinder piston rod is realized by the expansion promotion piston rod of gas holder mesohigh nitrogen in this template rotary fluid pressure device oil hydraulic circuit, because the nitrogen in the gas holder is sealing fully, therefore further pressurized at the process mesohigh nitrogen of hydraulic cylinder piston rod retraction, when oil hydraulic cylinder rod chamber one side stops oil-feed, the high pressure nitrogen that is closed is like an air spring, thereby realized the high speed resilience, this design science is reasonable, can significantly improve the stretching speed of hydraulic cylinder piston rod.
2. the nitrogen of this template rotary fluid pressure device is closed in gas holder and the oil hydraulic cylinder rodless cavity, and the nitrogen in the oil hydraulic cylinder to-and-fro motion in the gas holder is recycled, and can avoid the wasting of resources, thereby save production cost.
3. the P-T mouth of this template rotary fluid pressure device second solenoid valve links to each other becomes total filler opening, the A-B mouth links to each other becomes total oil outlet, can increase the flow of small flow solenoid valve thus, use the solenoid valve of lower price can satisfy user demand, help improving the running speed of oil hydraulic cylinder.
4. this template rotary fluid pressure device scientific structure design is reasonable, by the oil hydraulic cylinder rodless cavity is connected with a gas holder, in the oil hydraulic cylinder rodless cavity, be full of high pressure nitrogen, rely on gas pressure to realize stretching out fast of hydraulic cylinder piston rod, thereby the fast rotational of control template, it is low, stable to install whole cost, can effectively enhance productivity.
Description of drawings
Fig. 1 is an oil hydraulic circuit schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
This template rotary fluid pressure device, by motor 1, oil pump 2, solenoid valve and oil hydraulic cylinder 5 constitute, its innovative point is: the oil pump oil outlet is connected with the oil hydraulic cylinder rod chamber by pipeline road, be provided with first solenoid valve 3 between oil pump and the oil hydraulic cylinder, this first solenoid valve T mouth is connected in fuel tank, pipeline road between the oil pump and first solenoid valve is provided with electromagnetic relief valve 8, pipeline road between first solenoid valve and the oil hydraulic cylinder is provided with second solenoid valve 4, the P-T mouth of this second solenoid valve links to each other becomes total filler opening, the A-B mouth links to each other becomes total oil outlet, can increase the flow of small flow solenoid valve thus, use the small flow solenoid valve can satisfy user demand, and first solenoid valve can adopt electro hydraulic valve to match with it with big flow, thereby further reduce the cost of this hydraulic pressure installation control unit.Motor, oil pump, first solenoid valve, second solenoid valve and oil hydraulic cylinder rod chamber constitute an oil hydraulic circuit.The oil hydraulic cylinder rodless cavity is connected with a gas holder 7 by gas piping, in oil hydraulic cylinder rodless cavity and gas holder, be filled with compressed inert, this inert gas is nitrogen or helium, and the suction port of gas holder is connected with an inflator 6, provides high pressure nitrogen by it in gas holder.
Working principle of the present utility model is:
Motor driving oil pump pressure oil output, when first solenoid valve, second solenoid valve are switched on simultaneously, oil pump is transported to the oil hydraulic cylinder rod chamber with pressure oil, pressure oil promotes the high pressure nitrogen in piston rod withdrawal and the compression rodless cavity, because the nitrogen in the gas holder is closed, nitrogen pressure further raises in the gas holder in the process of piston rod withdrawal; When the energising of second solenoid valve, during the first solenoid valve no electric circuit, oil pump stops to rod chamber discharge pressure oil, nitrogen expansion in the gas holder and then promotion piston rod stretch out, the hydraulic oil of rod chamber is got back to fuel tank, realize the quick to-and-fro motion of oil hydraulic cylinder, thereby the fast rotational of control template further improves foundry production line manufacturing efficiency.
