Embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the present invention is further illustrated.
Embodiment
As shown in Fig. 1-2, Fig. 1 is structural representation of the present invention; Fig. 2 is the structural representation of pedal-operated oil pump.
A kind of hydraulic press, comprise door frame 1 and the worktable 2 be arranged on door frame 1, the oil hydraulic cylinder 3 with piston rod 31, in the cylinder of one end connecting fluid cylinder pressure 3 of piston rod 31, the other end of piston rod 31 is towards worktable 2, a kind of hydraulic press, also comprise pedal-operated oil pump 4, pedal-operated oil pump 4 is connected by oil pipe 5 with oil hydraulic cylinder 3; Replace the motion of a hand with foot motion, when in use, two hands can grasp workpiece simultaneously, reach the object of safety operation.
Arrange high-capacity pump 6 and low-capacity pump 7 in pedal-operated oil pump 4, low-capacity pump 7 and high-capacity pump 6 connected pipes 5 respectively, makes operation more flexible.
Low-capacity pump 7 comprises small pump core 71 and the little pump housing 72, the sheathed little pump housing 72 outside small pump core 71.
The arranged outside large pump core 61 of the little pump housing 72, the top of the large pump housing of the sheathed large pump housing 62,62 in outside of large pump core 61 arranges foot-driven lever 8; Step on foot-driven lever 8, large pump core 61 and small pump core 71 press down simultaneously, reach the object of fuel feeding simultaneously.
The position that low-capacity pump 7 and high-capacity pump 6 are connected with oil pipe 5 arranges little oil pump outlet valve 73 and large oil pump outlet valve 63 respectively, reaches the object of hydraulic control oil mass.
As shown in Fig. 3-Fig. 5, Fig. 3 is the positional structure schematic diagram of guiding valve; Fig. 4 is the structural representation of large oil pump outlet valve; Fig. 5 is the structural representation of little oil pump outlet valve.
A kind of hydraulic press, also comprise guiding valve 9, high-pressure oil duct 10, large oil pump outlet valve 63 connects guiding valve 9, and guiding valve 9 is arranged on high-pressure oil duct 10, and arrange low pressure oil duct 91 on the downside of that one end that guiding valve 9 is connected with large oil pump outlet valve 63, low pressure oil duct 91 is communicated with fuel tank 11.
The flow of low-capacity pump 7 is 2ml/ time-5ml/ time, and the flow of high-capacity pump 6 is 11ml/ time-17ml/ time; Namely when stepping on foot-driven lever 8, the numerical value of each oil pump capacity.
In the mode of execution of optimum of the present invention, hydraulic press selects the hydraulic press of 25 tons, the flow set of low-capacity pump 7 is become 3.6ml/ time, and the flow set of high-capacity pump 6 becomes 14ml/ time, not only easy to operate, also reaches durable object.
When stepping on foot-driven lever 8, large pump core 61 and small pump core 71 press down simultaneously, oil in the large pump housing 62 chamber enters high-pressure oil duct 10 through excessive oil pump outlet valve 63; oil in the little pump housing 72 chamber enters high-pressure oil duct 10 through too small oil pump outlet valve 73; along with system pressure constantly rises; large oil pump outlet valve 63 shuts gradually; and now guiding valve 9 is moved to the left; open one-way valve; the large endoceliac oil of pump enters fuel tank 11 by low pressure oil duct 91; now only have the endoceliac high pressure oil of little pump to enter high-pressure oil duct 10 injection liquid compressing cylinder, and the large endoceliac oil of pump leads to fuel tank 11.
