Above mentioned work station 7 is the jack hydraulic press that the applicant mentions in background technology hurdle.
Due to the air pump inlet valve 1411 illustrated in figure, first, second largest oil pump inlet valve 1421, 1431 and the structure of little oil pump inlet valve 1441 and function be all identical, therefore applicant only selects air pump inlet valve 1411 and is described below: for the location status shown in Fig. 2, correspond to air pump inlet valve 1411(steel ball) rear side be disposed with a spring 1412, one spring-loaded steel ball 1413 and a stop screw 1414, one end of spring 1412 is bearing on air pump inlet valve 1411, the other end is bearing on spring-loaded steel ball 1413, and spring-loaded steel ball 1413 contacts with stop screw 1414, stop screw 1414 screws on valve body 1.Hydraulic oil backs down or claims to push up the dynamics opening air pump inlet valve 1411 to be determined by the spring force of spring 1412.Again, due to air pump delivery valve 1512, greatly, little oil pump outlet valve 1522, 1532, air pump oil return pressure regulator valve 1513, structure and the function of large blowback oil pressure regulator valve 1523 and little blowback oil pressure regulator valve 1533 are all identical, therefore applicant only selects air pump delivery valve 1512 and is described below: corresponding to air pump delivery valve 1512(steel ball) left side (for location status shown in Fig. 2) be disposed with pressure spring 15121, pressure spring supporting steel ball 15122 and adjustment screw 15123, one end of pressure spring 15121 is bearing on air pump delivery valve 1512, the other end is bearing on pressure spring supporting steel ball 15122, and pressure spring supporting steel ball 15122 contacts with adjustment screw 15123, adjustment screw 15123 screws on valve body 1.Clockwise or the counterclockwise adjustment adjusting screw 15123 is acted on by pressure spring supporting steel ball 15122 pairs of pressure springs 15121, and then acted on by pressure spring 15121 pairs of air pump delivery valves 1512, thus reach the effect regulating the hydraulic oil top in air pump oil road 151 to open the dynamics size of air pump delivery valve 1512.Owing to can be fully understood the valve that all the other do not describe by the example of drawing inferences about other cases from one instance, therefore applicant repeats no longer one by one.Again, only aforesaid relief valve 1542 is without the need to arranging spring, directly by the relief valve handle screwed on valve body 1 15421 pairs of relief valve 1542(steel ball valves) discharge or limit.
Ask for an interview Fig. 4 and Fig. 5, for manual operation oil pump 4, when hydraulic oil will be provided to work station 7, that is when pressure oil will be provided to the oil cylinder 711 of the decompressor 71 of work station 7, so that make the oil cylinder post 7111 of oil cylinder 711 in the cylinder body of oil cylinder 711 to outer stretching, extension to the workpiece punching press be placed in falsework 72 or do the action of other similar requirement time, so showing by with the cotter way 433(Fig. 2 on oil pump post 43) the aforementioned hand 51 of pressing that connects drives oil pump post 43 to move up and down, specifically operated pressing hand lever 6 alternately up and down by operator.In this process, when the oil pump post 43 of oil pump 4 is descending, first oil pump inlet valve 1421, second largest oil pump inlet valve 1431 and little oil pump inlet valve 1441 are opened, first pump oil input channel 142, second largest pump oil input channel 143 and little pump oil input channel 144 are simultaneously to large pump plunger shaft chamber 41 oil-feed, now, with pump greatly large oil pump outlet valve 1522 that oil duct 152 communicates and little oil pump outlet valve 1532 cuts out; Otherwise, when oil pump post 43 is up, then first, second large oil pump inlet valve 1421,1431 and little oil pump inlet valve 1441 are closed, and large oil pump outlet valve 1522 and little oil pump outlet valve 1532 are opened, the hydraulic oil previously entered in large pump plunger shaft chamber 41 also can be described as oil-out through total oil road 17 from pressure release oil duct oil-out 1541() oil cylinder 711 of the decompressor 71 of work station 7 is entered through fluid pressure line 15411, oil cylinder post 7111 stretches outside the cylinder body of oil cylinder 711, thus realizes rapid pump oil.When stressed, when the pressure of the hydraulic oil namely in large pump plunger shaft chamber 41 raises, the large blowback oil pressure regulator valve 1523 pumped greatly on the oil circuit of oil duct 152 is backed down by pressure oil, pressure oil in large pump plunger shaft chamber 41 returns in the oil storage cylinder chamber 21 of oil storage cylinder 2, and the little oil pump outlet valve 1532 of pressure oil through opening in little pump plunger shaft chamber 42 continues to enter total oil road 17 and draw from pressure release oil duct oil-out 1541, thus realize the large forced feed of little oil mass.Work station 7 has worked rear unlatching relief valve 1542, and the hydraulic oil in the oil cylinder 711 of decompressor 71 enters in oil storage cylinder 21 for 164 times through pressure release oil duct oil-out 1541, pressure release oil duct 154 and pressure release oil spill port successively under the effect of oil cylinder post return spring (not shown) acting on oil cylinder post 7111.
When enabling air pump 3, with behavior example under the pump core of air pump 3, the hydraulic oil in oil storage cylinder chamber 21 sucks from little pump oil input channel 144, because air pump inlet valve 1411 is now in opening, therefore hydraulic oil enters in air pump oil pocket 31, and air pump delivery valve 1512 is now in closed condition.Otherwise when the air pump core of air pump 3 is up, air pump inlet valve 1411 cuts out, and air pump delivery valve 1512 is opened, the hydraulic oil previously entered in air pump oil pocket 31 enters total oil road 17 through air pump oil road 151, is exported by pressure release oil duct oil-out 1541.
In sum, technical scheme provided by the invention has cashed the technique effect referred in the superincumbent technique effect hurdle of applicant, and the device in apparatus of the present invention and prior art is carried out pump oil to contrast, under identical operation, the pump speed oil of oil pump 4 improves more than five times than prior art, and operator is comparatively light to the manipulation of pressing hand lever 6.
