The distance between upper surface be equal to the 2/3 of the thickness of sheet material 8；When sheet material 8 is thrust, drift 7 promotes the piston rod of cushion dashpot 1
120 is descending, and the plate swept away contacts with buffer board 2, and cushion dashpot 1 has upward opposition to descending drift 7, reduces
The instantaneous impact of drift 7 when thrusting, piston rod 120 are gradually taken in cylinder body, and hydraulic oil is pressed into accumulator 3 in rodless cavity；
After the lower pressure of drift 7 eliminates, pressure oil is pushed back into rodless cavity again again in the presence of accumulator 3, piston rod 120 is up
Reset；Such a structure design, buffering effect is improved, and cushion dashpot 1 can automatically reset, and ensure punch press continuous firing.Work as needs
When being filled with hydraulic oil into accumulator 3, the electromagnet of switch valve 4, which is powered, to be connected, and the import of switch valve 4 connects pressure oil, pressure oil
It is filled with by switch valve 4 in the rodless cavity of accumulator 3 and cushion dashpot 1, is more than the setting of overflow valve 5 in the pressure oil pressure being filled with
During pressure, unnecessary hydraulic oil flows back to fuel tank from overflow valve 5, now, the electromagnet power-off of switch valve 4, fuel cut-off.When need
When discharging hydraulic oil in accumulator 3, the import connected tank of switch valve 4, the electromagnet of switch valve 4, which is powered, to be connected, the He of accumulator 3
Pressure oil flows back to fuel tank by switch valve 4 in the rodless cavity of cushion dashpot 1, obtains pressure release.
From the foregoing, it will be observed that by the buffering hydraulic cylinder system of the present embodiment, increase cushion dashpot 1 on punch press, from punching plate
Lower section is supported, and when plate will be thrust, plate contacts with buffer board 2, and cushion dashpot 1 starts to intervene, to drift 7 have to
On direction active force, so as to will not instantaneously increase in the moment thrust, the impulsive force of drift 7, effectively reduce making an uproar when thrusting
Sound and vibrations, also avoid, to the impact inside punch press, improving the service life of punch press.
Schematically the utility model and embodiments thereof are described above, this describes no restricted, accompanying drawing
Shown in be also one of embodiment of the present utility model, actual structure is not limited thereto.So if this area
Those of ordinary skill enlightened by it, do not depart from the utility model create objective in the case of, without creativeness design
The frame mode similar to the technical scheme and embodiment, the scope of protection of the utility model all should be belonged to.
