Abstract
The utility model discloses a multi-functional hydraulic machine, which consists of an electric motor and an oil tank. The hydraulic machine is characterized in that the electric motor drives a high-pressure hydraulic pump, the oil inlet of which is communicated with the oil tank and the oil outlet of which is connected with the oil inlet chamber of a manual change valve; the back-oil chamber of the manual change valve is communicated with the oil tank, and the two working oil chambers of the valve are communicated with the two oil chambers of the double-oil channel high-pressure hydraulic cylinder via oil paths. The multi-functional hydraulic machine is provided with the advantages of small dimension, large tonnage capacity, light weight, convenience in moving and operation, and so on. As a small multi-functional hydraulic machine, the hydraulic is applicable for the techniques of press mounting, correcting, cold and hot riveting, tension compressing, extrusion forming, and so on, and is in particular applicable in the national industrialized household production.
Description
Technical field
The utility model relates to a kind of hydraulic press, a kind ofly specifically can be used for press-fiting, the multifunctional solution press of function such as correction, cold and hot riveting, tension and compression, extrusion modling.
Background technology
Hydraulic press in the market has uses gear driven, use the engagement between the gear teeth and the gear teeth to drive hydraulic press work in use, but volume is all heavier, and it is not firm through regular meeting engagement to take place, and causes to get loose.Though there is the hydraulic press of minority to adopt equipments such as reversal valve on the market, large-tonnage hydraulic press compacting area is big, rise press highly big, volume is big, Heavy Weight and the market price are also high, limited it and be extensive use of.
The utility model content
The utility model is to overcome the deficiencies in the prior art, provides a kind of simple and practical, the tonnage height, volume is little, and is easy and simple to handle, in light weight, be convenient to move, multifunctional solution press easy to maintenance can be used for the press-fiting of metal works, correction, cold and hot riveting, tension and compression, extrusion modling etc.
The technical solution of the utility model is as follows:
A kind of multifunctional solution press, comprise motor, fuel tank, it is characterized in that described motor provides driving for high-pressure hydraulic pump, the oil-in of high-pressure hydraulic pump and fuel tank UNICOM, the oil-out of high-pressure hydraulic pump is connected with the oil suction chamber of hand-operated direction valve, and the oil back chamber and the fuel tank of hand-operated direction valve link; Two working oil chambers of hand-operated direction valve link by oil circuit with two oil pockets of two oil circuit high pressure liquid cylinder pressures respectively.
By oil suction filter UNICOM, link by return filter between the oil back chamber of hand-operated direction valve and the fuel tank between the oil-in of high-pressure hydraulic pump and the fuel tank.
Be provided with overflow valve between the oil suction chamber of hand-operated direction valve and the oil back chamber.
Be connected with balanced valve in the oil circuit between the working oil chamber of hand-operated direction valve and the two oil circuit high pressure liquid cylinder pressure oil pocket.
The oil-out of high-pressure hydraulic pump is connected with Pressure gauge.
The utlity model has following characteristics:
The utlity model has that volume is little, tonnage is high, in light weight, advantage such as be convenient to move, easy and simple to handle, it is a kind of multi-functional small-sized hydraulic machine, can be used for press-fiting, technologies such as correction, cold and hot riveting, tension and compression, extrusion modling, be particularly useful for whole people's industrialization family and produce.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
The utility model comprises motor 3, fuel tank 5 in the drawings, motor 3 provides driving for ultrahigh-pressure hydraulic pump 4, the oil-in of ultrahigh-pressure hydraulic pump 4 is connected with fuel tank 5 by oil suction filter 7, and the oil suction chamber of the oil-out of ultrahigh-pressure hydraulic pump 4 and hand-operated direction valve 9 links.The oil back chamber of hand-operated direction valve 9 links by a return filter 6 and fuel tank 5; Two working oil chambers of hand-operated direction valve 9 link by oil circuit with two oil pockets of two oil circuit ultrahigh-pressure hydraulic cylinders 1 respectively.Be provided with overflow valve 8 between the oil suction chamber of hand-operated direction valve 9 and the oil back chamber simultaneously.Be connected with balanced valve 10 in the oil circuit between hand-operated direction valve 9 working oil chambers and two oil circuit ultrahigh-pressure hydraulic cylinder 1 oil pocket.The oil-out of ultrahigh-pressure hydraulic pump 4 is connected with Pressure gauge.After motor 3 started, ultrahigh-pressure hydraulic pump 4 fuel feeding were through hand-operated direction valve 9 meta oil returns, and two oil circuit ultrahigh-pressure hydraulic cylinders 1 are not worked; When the handle that promotes on the hand-operated direction valve 4, when making hand-operated direction valve 9 be in the work of position, a left side, hydraulic oil enters in the oil pocket of two oil circuit ultrahigh-pressure hydraulic cylinders 1 through the check-valve port in the balanced valve 10, cylinder piston is stretched out in the cavity, hydraulic press is started working, at this moment hydraulic press configuration auxiliary mould can proofread and correct alignment, press-fit, cold and hot extruding, riveted joint, stretching, bending, shearing etc.When the handle on promoting hand-operated direction valve 9 makes hand-operated direction valve 9 be in the work of right position, hydraulic oil enters in another oil pocket of two oil circuit ultrahigh-pressure hydraulic cylinders 1, open balanced valve 10 simultaneously, first oil pocket fluid is flowed back in the fuel tank 5, and the overflow valve 8 of ultrahigh-pressure hydraulic pump 4 outlets plays the safety valve effect.
