Abstract
The utility model relates to a liquid storage tank for mixed powder electric spark machining. A liquid feed pump is arranged on the end cover at the top of a tank body in a liquid storage tank; the bottom of the tank body forms a cone; a discharging pipeline and a cut-off valve are arranged at the vertex of the cone. A liquid surging rabbling mechanism passes through the centerline of the tank body and is welded with the bottom of the tank body; one end of the liquid surging rabbling mechanism is sealed, and the other end is connected with a throttling valve. Both sides of the liquid surging rabbling mechanism are provided with a plurality of liquid surging holes. Mixed powder working liquid output from the liquid feed pump is controlled and divided into two paths by the throttling valve, one path of the working liquid is transported to a working liquid tank to carry out the electric spark machining, and the other path is transported to the liquid surging rabbling mechanism and flows out from the liquid surging holes of the liquid surging rabbling mechanism to carry out liquid surging rabbling for the working liquid. The utility model has the advantage of reasonable structure, and improves the deficiencies of the existing liquid storage tank.
Description
The utility model relates to the liquid reserve tank that spark machined is used in a kind of machine-building.
Mixing the powder spark machined is a spark machined new technology that just occurs in recent years, it is by adding electric conductivity attritive powders such as silicon, aluminium in the electric spark working solution, change the spark discharge state, discharge is evenly distributed at finished surface, thereby reduce the machined surface roughness value, improve machined surface quality.The appearance of this technology has solved fundamentally that common electrical spark machined surface roughness value is big, the shortcoming of machined surface quality difference, makes spark machined finally be processed into possibility as accurate, complex profile.Reduced simultaneously product production process, reduced working strength of workers.Therefore the appearance of this technology has important economic value.For guaranteeing that powder-mixed dielectric fluid is not by big galvanic corrosion particle contamination, mix the powder spark machined and generally only be used for fine finishining, therefore mix the powder electric spark machine tool two cover working solution circulating systems are arranged, promptly be used for rough machined common working solution circulating system and be used for the accurately machined powder-mixed dielectric fluid circulatory system, two systems are by compositions such as liquid reserve tank, work tank, solution feed pump and connecting lines, work tank two systems can be public, but liquid reserve tank must be separate.One of key technology of mixing the powder spark machined is to guarantee that institute adds powder and mixes in working solution, but owing to powder is a solid particle, its density is bigger than working solution density, and when working solution remained static, powder can precipitate.Have only the working solution of maintenance to be in continuous flow regime, under affinity effect between working solution and powder, powder just can be suspended in the working solution and working solution mixes.Therefore all designed towards the liquid rabbling mechanism in the liquid reserve tank of the powder-mixed dielectric fluid circulatory system,, made powder in working solution, keep suspending by stirring towards liquid.Liquid reserve tank in the existing powder-mixed dielectric fluid circulatory system has the following disadvantages: (1) liquid reserve tank is square (or rectangle), four wedge angles are arranged at the bottom of the case, flow at these sharp corner working solutions and to be subjected to bigger obstruction, flowing velocity reduces even remains static, so liquid reserve tank bottom sharp corner has powder precipitation; (2) in the liquid reserve tank towards the liquid rabbling mechanism dash the liquid mouth to dash the liquid direction inconsistent, the flowing velocity size and Orientation of formed working solution has nothing in common with each other, the mutual superposition of working solution flow velocity also can form the less or inactive state of flow velocity at regional area, also can produce powder precipitation.(3) towards the liquid rabbling mechanism to dash the liquid mouth inconsistent towards the liquid direction, make the mobile turbulent condition that is in of working solution in the liquid reserve tank, sneaking into bulky grain powder in the working solution or large granular impurity can be stirred under action of turbulent flow and float, enter work tank by solution feed pump, and then enter discharging gap, causing the bad phenomenon such as concentrated and discharge instability of discharging to take place, influencing crudy.
The purpose of this utility model is the deficiency that exists at prior art, proposes more reasonably liquid reserve tank of a kind of structure.
The purpose of this utility model is achieved in that liquid reserve tank is mainly by casing 1, solution feed pump 2, choke valve 3, choke valve 4, towards liquid rabbling mechanism 5, Pressure gauge 6, feed flow pipeline 7 and liquid back pipe road 8, drain line 9, stop valve 10 is formed, wherein: solution feed pump 2 is installed on the top end cover of casing 1, its pump housing partly is in casing 1 middle part, the bottom of casing 1 is conical, cone-apex angle is 150 °, drain line 9 and stop valve 10 are arranged to make things convenient for the replacing of working solution at vertex of a cone place, pass casing 1 center line and be welded in casing 1 bottom towards liquid rabbling mechanism 5, end sealing towards liquid rabbling mechanism 5, the other end links to each other with choke valve 4, its both sides have a plurality of towards liquid mouth 11,1 axis distributes axisymmetricly towards liquid mouth 11 along casing, the powder-mixed dielectric fluid of solution feed pump 2 outputs is through choke valve 3,4 controls are divided into two-way, one the road mixes the powder spark machined to work tank, another road carries out stirring towards liquid to working solution from liquid mouth 11 outflows of dashing towards liquid rabbling mechanism 5 to towards liquid rabbling mechanism 5.For guaranteeing the liquid reserve tank bottom powder to be had higher scouring capability towards the liquid rabbling mechanism, towards liquid mouth 11 horizontal downtilt angles α at 10 °～15 °.
The utility model has the advantages that: there is not wedge angle in (1) novel liquid reserve tank bottom, has prevented the precipitation of powder at sharp corner, attritive powder is formed in working solution to greatest extent mix.(2) the utility model helps the precipitation attritive powder is stirred, and has shortened attritive powder and has evenly mixed the required time in working solution, guarantees simultaneously except that big particle, mixes in the powder edm process and no longer includes new powder precipitation.(3) can effectively separate the bulky grain powder or the impurity of sneaking in the working solution, make mixed powder spark machined more stable, also be beneficial to the powder-mixed dielectric fluid prolongation in service life simultaneously.

Embodiment: the liquid reserve tank diameter is φ 400mm, highly is 600mm; Solution feed pump is a vane pump, and its discharge capacity is 401/min, and maximum working pressure (MWP) is 0.4MPa.The utility model promptly can make in 15 minutes powder evenly mix in working solution starting solution feed pump, show by the sampling of different parts in liquid reserve tank detection, liquid reserve tank is place's generation small amount of precipitate in the middle of the bottom only, other position does not have precipitation and produces, and mostly being big particle in this part sediment, mixed powder spark machined is stable to keeping, the raising crudy is favourable for this.
