The utility model has the advantages that the steel wires are wound outside the boosting cavity, and the lower side of the boosting cavity is provided with the pressure resistant plate which is in bolt connection with the boosting oil tank, thus the boosting cavity can not only bear larger radial pressure, but also bear larger axial pressure; the oil pipe is provided with the superhigh pressure one-way valve to prevent hydraulic oil from inversely flowing and overflowing, thereby having high safety factor, long service life, low energy consumption and high efficiency.
Description
Technical field
The utility model relates to the press that improves density behind a kind of powder compacting, is specifically related to a kind of steel wire and twines isostatic pressing machine.
Background technology
At present, steel wire twines isostatic pressing machine and generally comprises main frame that the high-strength alloy spring steel wire twines, high pressure chest, booster body etc., external winding steel wire of the booster cavity of booster body, though this isostatic pressing machine can bear bigger radial load, safety coefficient is bigger, service life is longer, but knowing from experience, booster cavity wherein makes its fracture because of bearing big axial force, security incident takes place, and the oil in the booster cavity enters under the high pressure effect and easily takes place in the high pressure chest to reflux and overflow phenomena, thereby cause power consumption higher, inefficiency.
Summary of the invention
Purpose of the present invention is intended to overcome above-mentioned shortcoming, provides that a kind of safety coefficient is big, long service life, power consumption is low, efficient is high steel wire twine isostatic pressing machine.
For achieving the above object, the utility model adopts following solution: a kind of steel wire twines isostatic pressing machine, comprise movable machine frame, high-pressure chamber, booster body, movable machine frame adopts high-strength alloy spring steel wire coiled, high-pressure chamber is installed in the middle of it, push cylinder and roller are set below, movable parts such as guide rail, booster body comprises pressurizing cylinder and supercharging cavity, the outside winding steel wire of supercharging cavity, the supercharging cavity is communicated with by oil pipe with high-pressure chamber, it is characterized in that: the resistance to compression plate is set below the supercharging cavity, is connected with bolt between resistance to compression plate and the pressurizing cylinder.
Above-mentioned steel wire twines isostatic pressing machine, it is characterized in that: on the oil pipe of described connection supercharging cavity and high-pressure chamber the super-pressure check valve is set.
Compared with prior art, the utlity model has following advantage:
1, because the outside winding steel wire of the utility model supercharging cavity, in the process of supercharging, can bear bigger radial pressure, be provided with and the bolted resistance to compression plate of pressurizing cylinder below the supercharging cavity, the supercharging cavity just can bear bigger axial compressive force in the process of supercharging like this, and safety coefficient is big, the advantage of long service life so the utlity model has.
2, the utility model is provided with the super-pressure check valve on the oil pipe that is communicated with supercharging cavity and high-pressure chamber, its action principle is under the effect of Hydraulic Station oil pump certain pressure, open the check valve plug, oil is injected in high pressure chest and the booster cavity by oil pipe, make to reach in communicating pipe in their two chambeies all to have after the oiling pressure, stop oiling; At this moment start pressurizing cylinder, the oil in the booster cavity is entered in the high pressure chest under the high pressure effect, product and oil volume in the high pressure chest are diminished, it is big that proportion becomes, the purpose of static pressure such as reach, this moment, super high-pressure single was blocked oiler inflexibly to valve core, made oil must not return pouring orifice; When finishing supercharging, the pressurizing cylinder piston is return original position, and at this moment high pressure chest pressure interior, the interior oil of booster cavity is got back to oiling pressure, and the spool of check valve is opened, and oil is got back to fuel tank, and whole process is finished.In the course of work that waits static pressure, because the effect of check valve, refluxing and overflow phenomena can not appear in the oil in the high pressure chest, so the utlity model has the advantage that power consumption is low, efficient is high.
