Description
The utility model relates to a kind of combined pneumatic oil hydraulic cylinder, can extensively use as the pneumatic hydraulic element in the numerous areas such as punching press, welding, riveted joint, driving clamping device, is specially adapted to sheet stamping and welding procedure.
The method that produces the great number working pressure at present used all kinds of gas, the fluid cylinder has two kinds: the one, and directly utilize high pressure oil to drive working piston work for power, it must be equipped with hydraulic station, this just causes cost high, and this mode of surging makes auxiliary movement slow; The 2nd, be power with the low-pressure gas, design gas-liquid cylinder according to liquid incompressibility and force balance principle, Conversion of energy with low-pressure gas is the hydraulic pressure energy of high pressure earlier, drive working piston again, this method is because will be pneumatic and surge and organically combine, not only satisfy the requirement of working voltage power but also given full play to the pneumatic advantage that is swift in motion, thereby become following developing direction.
Gas-liquid cylinder of the prior art, a kind of is only to use as supercharging character, as pneumohydraulic pressure-cylinder, the just high pressure oil of its output is still needed and just can be utilized by the equipment that is equipped with it; Another kind of gas-liquid power-increasing cylinder has solved this problem preferably, and its direct output services pressure is similar to general pneumatic cylinder, oil hydraulic cylinder, and remains in deficiency on its structure.At first, whether the closing of the passage between high pressure oil area and the low pressure oil district is to rely on this passage to realize with interrupted contact of piston rod, and this just makes the Sealing at sealing place very easily wear and tear and make oil liquid leakage; Secondly by compression spring provided when the backhaul power of piston rod was the dependence process, because spring has absorbed portion of energy during process, thereby had reduced the pressure of high pressure oil, and the hydraulic oil supercharging is reduced; Because of being subjected to the high-voltage oil cylinder place to need the structural constraint of aspect such as open pore, make the reduced cross-sectional area of drift contact high pressure oil in addition, cause force increasing ratio lower.
The purpose of this utility model provides a kind of improved novel pneumatic oil hydraulic cylinder with regard to being to avoid existing deficiency in the prior art.
The purpose of this utility model is achieved like this: pneumatic hydraulic cylinder is made up of two-part: (one) cylinder part comprises that drift, guide sleeve, flange plate, cushion pad, high-voltage oil cylinder, low pressure oil cylinder, cylinder, cylinder block, cylinder block, jumper bar, thick piston, thin piston, pad, bonnet, pull bar etc. form; (2) control section comprises compositions such as solenoid valve 1DT, 2DT, 3DT and pressure relay YJ.
Because the utility model has been offered B, F hydraulic fluid port on cylinder block, jumper bar is remained with the cylinder block endoporus contact, thereby reduce the wearing and tearing that cause because of interrupted contact; And realize the connection and the disconnection of left and right sides oil pocket by the solenoid valve 2DT of control section.
Because the utility model has been offered C, E gas port on cylinder block, replace the effect of spring with this, and eliminated pressure loss of energy in the process, and the surface of contact of drift piston portion and high pressure oil is enlarged as much as possible, has increased force increasing ratio.
The utility model advances, snap back, a series of sequentially-operatings such as stops by the F.F. that is used for realizing drift, the worker of control section, its working procedure is as follows: the 1DT energising, spool moves to left, 3DT switches on, spool moves to right, C, the air inlet of E mouth, and thick piston moves to left, extruding sealing fluid enters the B mouth by the F mouth, pressure oil promotes drift and moves to left fast, to propping up workpiece, finishes F.F.; Then, the C mouth pressure raises, and pressure relay YJ sends electrical signal, the 2DT energising, spool moves to right, and B, F mouth disconnect, the 3DT outage, spool moves to left, D, the air inlet of C mouth, and thin piston drives jumper bar and moves to left, sealing fluid in the extrusion oil cylinder cylinder body left side oil pocket (surrounding) by drift, high-voltage oil cylinder, cylinder block, make its supercharging, high pressure oil promotes drift and moves to left, and finishes to workpiece processing; Subsequently, the 1DT outage, spool moves to right, the 2DT outage, spool moves to left, and B, F hydraulic fluid port are communicated with, A, the air inlet of E gas port, drift, jumper bar, thick piston, thin piston all move to right fast, return to original position, so far finish a work cycle.
This pneumatic hydraulic cylinder compared with prior art has following advantage:
1, simple in structure.Just be equivalent to the simple series connection of three gas, fluid cylinder.
2, supercharging, force increasing ratio is big.On the cylinder block C, E mouth offer the effect that has substituted spring, thereby cause energy loss because of the spring pressurized when having eliminated process, pressure ratio reduces; The expansion of drift right-hand member piston cross-section acts on the whole piston cross-section high pressure oil, thereby has enlarged force increasing ratio.
3, the backhaul speed adjustable range is big.The size of the passage in the prior art between pressurized cylinder two oil cylinders is subjected to the restriction of jumper bar sectional area, and the jumper bar cross section is subjected to pressure ratio restriction and can not be too little, thereby causes that the liquid Peak Flow Rate is restricted between two oil pockets.Among the design by on cylinder block, offer B, the F mouth has solved this problem well, and the backhaul speed adjustable range is increased, and on this basis, can connect series flow control valve again on the pipeline between B, the F mouth, with speed governing at any time.
4, easily be automated.Utilize control devices such as pressure, stroke, time, make pneumatic hydraulic cylinder realize automation easily.
5, sealed member is safe and reliable, and is not easy to wear.Because the offering of B, F mouth on the cylinder block, avoided between cylinder block and the jumper bar contacting the heavy wear that causes Sealing because of interrupted.
