[specific embodiment]
With reference to accompanying drawing 1, this kind high-speed hydraulic punch press, comprise fuselage 102, last slide unit 104, oil cylinder 106, fuel tank 101, high-pressure oil pump 113 and motor 110, last slide unit 104 activities are located on the fuselage 102 and are connected with the piston rod 105 of oil cylinder 106, the cylinder body of oil cylinder 106 is fixed on the fuselage 102, be fixed with working plate 103 under the last slide unit 104, described fuselage 102 is installed on the fuel tank 101, described oil cylinder 106 is energy-efficient oil cylinder, counterbore forms oil pocket A in the middle of the piston rod bottom surface of oil cylinder, form oil pocket B between the piston rod bottom surface of oil cylinder and the cylinder block, form oil pocket C between the piston rod periphery of oil cylinder and the cylinder block, the stress surface area of oil pocket C is slightly larger than the stress surface area of oil pocket A, the bottom of described oil cylinder 106 is fixedly connected with hydraulic control one-way valve 107, hydraulic control one-way valve 107 is fixed on the oil-filled case 109 by valve seat 108, oil-filled case 109 is fixed on the top of fuselage 102, high-pressure oil pump 113 is driven by motor 110, motor 110 is fixed on the fuel tank by motor cabinet 112, be connected with flywheel 111 on the output shaft of motor 110, flywheel stores energy when the oil cylinder idle stroke, discharges when impulse stroke.
With reference to accompanying drawing 2, the operation principle of this high-speed hydraulic punch press is: during idle stroke, the electromagnet F1 energising of magnetic valve 204, hydraulic oil is through magnetic valve 204,207 enter the A chamber of oil cylinder 106, because of the A cavity volume little, so it is downward fast that the piston rod of oil cylinder can promote slide unit, oil cylinder B chamber from the fuel tank oil suction, is played effect efficiently by hydraulic control one-way valve 107, the oil in oil cylinder C chamber is through magnetic valve 204 oil sump tanks, when arriving impulse stroke, the electromagnet F3 of magnetic valve 206 energising, hydraulic control one-way valve 107 is closed the passage of B chamber and fuel tank automatically, hydraulic oil enters oil cylinder B chamber through magnetic valve 206, because oil cylinder B cavity volume is big, thus the deceleration automatically of oil cylinder piston bar, and pressure increases, the energy of flywheel discharges simultaneously, make high-pressure oil pump export hydraulic oil reposefully, slide unit is finished the work in the promotion, plays energy-conservation effect; During backhaul, the electromagnet F1 outage of magnetic valve 204, F2 energising, the electromagnet F4 energising of magnetic valve 207, hydraulic oil enters the A chamber and the C chamber of oil cylinder simultaneously through magnetic valve 204,207, because the stress surface area in C chamber is a bit larger tham the stress surface area in A chamber, so just utilize the differential principle in the hydraulic drive, make the last slide unit of piston rod drive of oil cylinder return original position fast, and the oil in B chamber plays effect efficiently once more through hydraulic control one-way valve 107 oil sump tanks.
