Isostatic press generally comprises main frame, hyperbaric chamber, supercharging device etc.Current domestic macrotype isostatic pressing machine supercharging device has two kinds: 1. the two reciprocal superchargings of boom of the single cylinder of the reciprocal supercharging 2. of single cylinder as shown in Chinese patent CN203532361U.These two kinds of supercharging devices have inevitable shortcoming.The former supercharging is slow, and efficiency is low.And the latter is difficult to align when the piston rod of oil cylinder connects with pressurized cylinder (chamber) and cause pressurized machine seal ring easily to damage, if equipment is used words frequently also may cause piston rod to pull; Also exist operation not smooth, the defect of inconvenient maintenance.
Summary of the invention
The utility model, for solving existing supercharging device defect and problem that particularly the reciprocating supercharging device of the two booms of single cylinder exists, provides a kind of twin-tub reciprocal supercharging device.
The utility model is to adopt following technological scheme to realize: the reciprocal supercharging device of twin-tub, comprise the first oil cylinder and the first pressurized cylinder that is connected in the first oil cylinder bottom, and the rod seal of the first oil cylinder is stretched in the chamber of the first pressurized cylinder; Also comprise the second oil cylinder and the second pressurized cylinder that is connected in the second oil cylinder bottom, the rod seal of the second oil cylinder is stretched in the chamber of the second pressurized cylinder; In the epicoele of the first oil cylinder and the second oil cylinder, be filled with liquid oils, the epicoele of the first oil cylinder and the second oil cylinder passes through pipeline connection; The cylinder body top of the first pressurized cylinder and the second pressurized cylinder has oil inlet hole, and bottom has oil outlet, and the first pressurized cylinder is connected with the fuel-displaced house steward of device through one-way valve respectively with the oil outlet of the second pressurized cylinder bottom.During work, the cavity of resorption oil-feed of the first oil cylinder, the cavity of resorption of the second oil cylinder are fuel-displaced, on the piston of the first oil cylinder, move the epicoele that the liquid oils in its epicoele is pressed into by the road to the second oil cylinder, the piston of the second oil cylinder is moved down, the piston rod of the second oil cylinder stretches into the second pressurized cylinder completely, liquid oils supercharging in the second pressurized cylinder is entered to pressure cavity (as the hyperbaric chamber of isostatic press) by bottom oil outlet, one-way valve and fuel-displaced house steward discharge, and meanwhile, the first pressurized cylinder is through its oil inlet hole oil-feed; Then, the cavity of resorption of the first oil cylinder is fuel-displaced, the cavity of resorption oil-feed of the second oil cylinder, on the piston of the second oil cylinder, move the epicoele that the liquid oils in its epicoele is pressed into by the road to the first oil cylinder, the piston of the first oil cylinder is moved down, the piston rod of the first oil cylinder stretches into the first pressurized cylinder completely, liquid oils supercharging in the first pressurized cylinder is entered to pressure cavity by bottom oil outlet, one-way valve and fuel-displaced house steward discharge, and meanwhile, the second pressurized cylinder is through its oil inlet hole oil-feed; Repeat above-mentioned working procedure, the reciprocal supercharging of implement device.
The utlity model has following useful technique effect: when 1, oil cylinder connects with pressurized cylinder, perpendicularity is good, avoid uneven wear seal ring, long service life; 2, supercharging efficiency is high, is equal to the two reciprocal superchargings of boom of single cylinder; 3, simple in structure being convenient to keeped in repair; 4, operate steadily, smooth and easy, reliable.The utility model can be used for the supercharging of various pressure cavity, is especially suitable as the supercharging device of isostatic press.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1.
In figure: 1-the first oil cylinder, 2-the first pressurized cylinder, 3-the second oil cylinder, 4-the second pressurized cylinder, 5-pipeline, 6-oil inlet hole, 7-oil outlet, 8-one-way valve, the fuel-displaced house steward of 9-.
Embodiment
The reciprocal supercharging device of twin-tub, comprise the first oil cylinder 1 and the first pressurized cylinder 2 that is connected in the first oil cylinder bottom, the rod seal of the first oil cylinder stretches into that in the chamber of the first pressurized cylinder, (it is to well known to a person skilled in the art routine techniques that so-called sealing is stretched into, normally between piston rod and pressurized cylinder inwall, be provided with seal ring, as shown in Figure 2); The rod seal that also comprises the second oil cylinder 3 and be connected in the second pressurized cylinder 4, the second oil cylinders of the second oil cylinder bottom is stretched in the chamber of the second pressurized cylinder; In the epicoele of the first oil cylinder 1 and the second oil cylinder 3, be filled with liquid oils, the epicoele of the first oil cylinder 1 and the second oil cylinder 3 is communicated with by pipeline 5; The cylinder body top of the first pressurized cylinder 2 and the second pressurized cylinder 4 has oil inlet hole 6, and the oil outlet that bottom has oil outlet 7, the first pressurized cylinders 2 and the second pressurized cylinder 4 bottoms is connected with the fuel-displaced house steward 9 of device through one-way valve 8 respectively.During concrete enforcement, the first oil cylinder 1 identical with the second oil cylinder 3 (being that physical dimension is just the same), the first pressurized cylinder 2 identical with the second pressurized cylinder 4 (being that physical dimension is just the same), the first oil cylinder 1 and the second oil cylinder 3 are realized the connecting port that its epicoele is communicated with by the road and are opened respectively the top at the first oil cylinder and the second oil cylinder, and fill the maximum volume that equals the epicoele of the first oil cylinder or the second oil cylinder in the volume of the liquid oils of the first oil cylinder and the second cylinder upper cavity oil, like this, can make full use of the effective travel of oil cylinder piston.The piston rod end of the first oil cylinder 1 and the second oil cylinder 3 has the radial hole corresponding with oil inlet hole radial position on the first pressurized cylinder 2 and the second pressurized cylinder 4, the piston rod end face of the first oil cylinder 1 and the second oil cylinder 3 has the axial bore communicating with radial hole on it, when piston rod moves to radial hole on it and oil inlet hole on pressurized cylinder overlaps (connection), can realize the oil-feed of pressurized cylinder, like this, can improve the supercharging efficiency of the pressurized cylinder of equal height.Between oil cylinder and pressurized cylinder, can be connected and fixed by flange stay bolt.
