The energy-saving accumulator can replace the original high-pressure air passage system of the hydro-pneumatic hammer for satisfying the requirement of stable running, which has the advantages of simple structure, low manufacturing cost, fast movement and long service life.
Description
Technical field
The utility model relates to a kind of liquid pneumatic hammer energy-saving accumulator.
Background technique
External electric liquid die hammer generally adopts full hydraulic system (so-called oil buy oil scheme), under general condition You flow velocity a lot (oily flow velocity are approximately about 20 meter per seconds, and the flow velocity of gas be approximately about 80 meter per seconds) low than the flow velocity of gas.Therefore, die hammer adopts short stroke, weight head to satisfy the requirement of blow energy usually.When domestic former steaming-empty die hammer is transformed into electric liquid hammer, adopt liquid gas slide valve system mostly, keep former hammer stroke (general 3 tons～16 tons die hammer ranges are approximately 1250-1500mm).In order to guarantee that enough blow energies must strengthen the bore of guiding valve, therefore movable slow and cause opening speed to slow down.Traditional electric liquid die hammer all need be equipped with the high-pressure gas circuit yarn and unite and satisfy the smooth running of high pressure oil.But this high-pressure gas circuit yarn system complex structure, the fabricating cost height, usage operation is slow, and the processed product time is long, and working life is short.
Summary of the invention
The purpose of this utility model provides a kind of liquid pneumatic hammer energy-saving accumulator, and the high-pressure gas circuit yarn of its alternative original liquid pneumatic hammer is united and satisfied the smooth running of high pressure oil, has simple in structurely, and fabricating cost is low, the advantage of the fast and long service life of action.For this reason, the utility model adopts master cylinder side external sealed to be provided with outer cylinder sheath, gap between master cylinder side and the outer cylinder sheath forms air-casing, be provided with piston in the master cylinder, be provided with the base mat that holds the piston lower end in the master cylinder of piston lower end, the master cylinder side roof part of piston upper end communicates with interior cover by the gas shunt, communicate high pressure oil output pipe and by the one-way valve high pressure oil pump that communicates of the master cylinder bottom of piston lower end.The said structure design has realized the purpose of this utility model.
The high-pressure gas circuit yarn system of the alternative original liquid pneumatic hammer of the utility model, the nitrogen that utilization is sealed up for safekeeping in the airtight air-casing absorbs, stores and release energy and satisfy the smooth running of high pressure oil, utilize the short stroke piston, make the action of liquid pneumatic hammer fast, make its processed product time short, reduced a large amount of machining periods, the formed product high conformity, have simple in structurely, fabricating cost is low, long service life and robust advantage.

Embodiment
As shown in the figure, a kind of liquid pneumatic hammer energy-saving accumulator mainly is made up of master cylinder 6, high pressure oil pump 10 and one-way valve 3.Master cylinder side external sealed is provided with outer cylinder sheath 4, and the gap between master cylinder side and the outer cylinder sheath forms air-casing 5.Be provided with piston 8 in the master cylinder, be provided with the base mat 1 that holds the piston lower end in the master cylinder of piston lower end.The master cylinder side roof part of piston upper end communicates with interior cover by gas shunt 11.Communicate high pressure oil output pipe 9 and of the master cylinder bottom of piston lower end by one-way valve and high-pressure oil pipe 2 high pressure oil pump that communicates.
Fill in the master cylinder of described piston lower end and be provided with hydraulic oil 7.Fill in the master cylinder of described piston upper end and the air-casing and be provided with nitrogen.Piston is to drop on the base mat, and the master cylinder in the base mat has an enough big volume, and the master cylinder volume in the base mat accounts for 50%～80% of master cylinder volume.
During use, piston of the present utility model is to drop on the base mat, and the master cylinder volume in the base mat is an enough big volume, has been full of hydraulic oil, is nitrogen in the master cylinder of the epicoele of piston and the air-casing, is hydraulic oil in the master cylinder of piston cavity of resorption.When high pressure oil pump starts, by one-way valve high pressure oil is injected in the master cylinder of piston cavity of resorption, make the hydraulic oil rising pressure of piston cavity of resorption; Piston is upwards pushed away, make the interior nitrogen of master cylinder of piston upper chamber enter air-casing by the gas shunt, nitrogen gas volume-diminished pressure is raise, when the pressure of pressure and high pressure oil pump output high pressure oil is identical, piston is motionless, one-way valve is closed automatically, is full of high-pressure and hydraulic oil in the master cylinder of piston lower end;
When high pressure oil output pipe (being connected) output high pressure oil with liquid pneumatic hammer control oil channel, descent of piston, high pressure nitrogen gas in the air-casing expands mobile to the epicoele of piston, at this moment, the hydraulic fluid pressure of piston cavity of resorption begins to descend, and unidirectional self-acting valve is opened, the high pressure oil of high pressure oil pump enters in the master cylinder of piston cavity of resorption, make the piston cavity of resorption that sufficient high-pressure and hydraulic oil be arranged, from the high-pressure and hydraulic oil that the high pressure oil output pipe is constantly exported, the hammer of carrying of finishing the liquid pneumatic hammer moves.
When the liquid pneumatic hammer did not need high pressure oil, high pressure oil pump was with high pressure oil again in the master cylinder of input piston cavity of resorption, and up to the upper and lower chamber of piston and the high pressure oil pressure of high pressure oil pump when equating, one-way valve is closed automatically, has been full of high-pressure and hydraulic oil in the master cylinder of piston lower end.Finished the accumulation of energy task of accumulator.
Elements such as high pressure oil pump, gas shunt and one-way valve are by being sold product, so be not repeated on the market.
In a word, the high-pressure gas circuit yarn of the alternative original liquid pneumatic hammer of the utility model system utilizes and seals up for safekeeping in the sealed gas chamber Nitrogen absorb, store and release energy to satisfy the even running of hydraulic oil, utilize the short stroke piston, make The action of liquid pneumatic hammer is fast, makes its converted products time short, has reduced a large amount of machining periods, the formed product high conformity, Have simple in structurely, cost of manufacture is low, long service life and robust advantage.
