The connection of the pump housing 13 of the present utility model, valve body 28, low-pressure plunger 11, high-pressure plunger 25, case lid 74, hydraulic oil container 48 is finished like this: low-pressure plunger 11 places and forms sliding pair in the pump housing 13 cavitys; In the pump housing 13 upper groove, be provided with dust ring 7, O type circle 8, back-up ring 9; Be connected with high-pressure plunger 25 heads with back-up ring 18 in the base apertures of low-pressure plunger 11, it is secondary to form the connection of floating; High-pressure plunger 25 outer cylinder surfaces are joined mutually by chance with plunger bushing 26 inner peripheries, form sliding pair; Plunger bushing 26 external cylindrical surfaces and valve body 28 mider holes match, and its bottom surface is equipped with copper packing 27, and copper packing 27 another planes contact with bottom plane, valve body 28 hole; Swivel nut 20 outside threads match with valve body 28 mider hole internal threads, and are matched with swivel nut 20 endoporus by plunger bushing 26 top outer cylinder surfaces, when screwing swivel nut 20, axially clamp plunger bushing 26, copper packing 27 simultaneously in valve body 28 holes; Valve body 28 is connected by bolt 57 with the pump housing 13, when screwing bolt 57, clamps O type circle 19 simultaneously; The pump housing 13 waists have an outer step to cooperate with case lid 74 respective aperture, and both are equipped with rubber pad 4 between the contact plane, and bolt 17 was gone here and there the pump housing 13 respective aperture, its helical thread portion and case lid 74 corresponding screw-internal thread fit; Screw 5 is loaded in the hole on the operating rod bearing 2, and by nut 6 lockings, screw 5 heads contact with the pump housing 13 outsides one boss, it act as and limits the lower position that operating handle 1 swings up and down, and damages parts to prevent low-pressure plunger 11, high-pressure plunger 25 from producing unnecessary axial mechanical pressure stress when only moving down limit position.Case lid 74 is fixed by plane on several screws 47 and the hydraulic oil container 48, is equipped with rubber pad 78 between the two, leaks to prevent fluid.
Hydraulic oil container 48 of the present utility model is provided with portable body: a pair of clasp 16 of tool, fork plate 52, connecting rod 50, base ring frame 49, a pair of steel pipe 46, a pair of clasp 16 is separately fixed at the both sides, a side upper end portion of hydraulic oil container 48, one end of fork plate 52 is fixed on the opposite side upper end portion of case lid 74, the other end of fork plate 52 is the opening slot type with an end of connecting rod 50 and is connected, the other end of connecting rod 50 is strand with an end of base ring frame 49 and is connected, the other end two heads and the steel pipe 46 of base ring frame 49 are grafting, and a pair of steel pipe 46 is welded on the lower bottom part both sides of hydraulic oil container 48.This novel fork plate 52 is realized its fixing with case lid 74 by electric welding, and an end of connecting rod 50 is realized with pitching being connected by two wing nuts 51 of plate 52, and the other end and base ring frame 49 formation pivoting support points.In the time will realizing guiding and supporting, unscrewing wing nut 51 makes it separate with fork plate 52, and base ring frame 49 separated with steel pipe 46, base ring frame 49 end skewed slots are placed on the clasp 16, connecting rod 50 is placed fork plate 52 again, screw wing nut 51 again, thus the handle effect that base ring frame 49 is played guide and support.
When using the utility model, unscrew ventilation filler plug 59, barometric pressure is entered in the casing of hydraulic oil container 48.Pivoted lever 79 is pulled non-return hour hands limit position, and this moment, gear 60,60 ' relatively rotated, and gear 60 drive double threaded screws 62 move down and compress cone valve 66 on conical valve base 67, and are line contact sealing.Cone valve 66 lower end surfaces interlock Steering triangle 68 moves down, and pushes steel ball 69 open separation, and steel ball 69 is opened; Meanwhile, gear 60 ' drives on the double threaded screw 62 ' and moves.This moment is because the effect of spring 70 ' makes steel ball 69 ' be in closed condition.Simultaneously because using to move and pushing cone valve 66 ' open of Steering triangle 68 ' rises operating handle 1 with handing up, low-pressure plunger 11 is linked move on the high-pressure plungers 25, promptly be in the oil suction state.At this moment steel ball 24,56,38 is in closed condition.Owing to move on the high and low pressure plunger 25,11, make to produce negative pressure in the chamber, at this moment steel ball 32,35 overcomes the elastic force of spring 31,36 separately and opens, and fluid sucks through the oil inlet hole 90 of high pressure oil sucting valve, again in oil circuit 80 enters the cavity of high-pressure plunger 25; Simultaneously, the low pressure oil sucting valve sucks oil through oil inlet hole 89, again in oil circuit 84 enters the low pressure oil pocket 81 of low-pressure plunger 11.Thereby finish the oil suction in high and low pressure chamber simultaneously.Press down operating handle 1 this moment again, the relative pump housing 13, plunger bushing 26 are made shifting movement down respectively to make low-pressure plunger 11 interlock high-pressure plungers 25, promptly be in the oil extraction state, at this moment steel ball 32,35 is in closed condition, and steel ball 24 is because the thrust that spring 23 is set also is in closed condition.The high and low pressure oil content was not discharged through steel ball 38,56 and was confluxed into fuel-intake connection this moment, and the cavity 98,99 on fuel-intake connection 44 enters the selector valve connected element more by the road.Thereby make pressure oil enter high pressure oil import oil circuit 58, oil circuit 82 on the joint 75, enter Steering triangle 68 peripheral cavitys to waist hole 83 through steel ball 69 valve ports, cavity by transport pipe joint 102 enters coupled hydraulic pressure transport pipe 14 again, and then enter the pressurizing chamber 101 of actuator, make the pressurization of rising of lead hydraulic tongs piston; Simultaneously the fluid of lead hydraulic tongs reseting cavity 95 is located cavity flow through hydraulic pressure transport pipe 15, Steering triangle 68 ' and is entered oilhole 65 ', 87 and return in the hydraulic oil container 48 through the open gap passage of cone valve 66 ' and conical valve base 67 '.Make operating handle pressing about in the of 1 again, thereby finish suction, oil extraction action.To realize the F.F. of lead hydraulic tongs piston.Upper and lower mould 96,97 matched moulds on lead hydraulic tongs piston enter crimped status, and along with outer carrying increases and oil pressure when increasing suddenly, then the low pressure oil of being discharged by low-pressure plunger 11 steel ball 24 of pushing sequence valve open all enters in the hydraulic oil container 48.The oil extraction of high-pressure plunger 25 then is to enter selector valve 3 until lead hydraulic tongs pressurizing chamber by pushing steel ball 38 open through swivel nut 41, pipeline 44.Steel ball 56 two ends are in closed condition because of there being pressure difference simultaneously, thereby lead hydraulic tongs piston is slowly advanced, to realize that originally novel is high-pressure low-flow working feed state.When upper and lower mould 96,97 is finished crimping work, counterdie 97 must retreat when resetting, and then with hand pivoted lever 79 is pulled to clockwise limit position, and the cone valve 66 of selector valve 3 is opened, steel ball 69 cuts out, cone valve 66 ' cuts out, and steel ball 69 ' is opened, and then is off-load rewind down state this moment, low pressure and mass flow fluid is to reseting cavity 95, the fluid of pressurizing chamber 101 is to hydraulic oil container 48, thereby realization low pressure and mass flow rewind down makes counterdie be reset to initial position.Thereby finish an operation cycle, go round and begin again according to this.
The utility model need not be used the power source of motor, diesel engine, petrol engine and so on owing to adopted said structure, simplifies the structure, and has reduced operator's technical requirements grade, has solved the not portative problem of field work personnel.Be specially adapted to the usefulness of the emergent oil pump of conduct when the motor-driven oil pump of contingency breaks down in little engineering work load construction and the large-engineering amount.
