In the time that needs up move plunger 2, air inlet 1001 stops air inlet, now the first spool 9 can down move and open the valve port of valve seat 7, fluid in oil storage tank 11 enters by in-line 801 approach valve seats 7 pad cylinder 5 inside that stretch, and fluid promotes plunger 2 and up moves under the compressed-air actuated pressure of oil storage tank 11 internal upper part.
In the time that plunger 2 moves to agretope, by air inlet 1001 air inlets, the first spool 9 is upwards promoted, until the first spool 9 is closed the valve port of valve seat 7, in the pad cylinder 5 that now stretches, form airtight oil pressure chamber.
In the time that plunger 2 is pushed downwards, in the pad cylinder 5 that stretches, oil pressure raises, and in the time that oil pressure is greater than certain pressure, fluid promotes the first spool 9 and moves downward, thereby opens the valve port of valve seat 7, and fluid flows back to oil storage tank 11 along in-line 801.
The thrust that device produces can be calculated by the ratio of the area of the first binding face 13 and the second binding face 14, so just can adjust thrust by the size of adjusting two binding faces.
As shown in Figure 2 and Figure 3, the valve head end face of valve seat 7 is provided with at least two circular holes 702 with respect to valve seat revenue centre symmetry, and is provided with locating hole 701, the first spools 9 taking valve seat center as the center of circle and can in pipeline, moves up and down by locating hole 701.
As shown in Figure 4, the second cylinder cap 10 inner sides are provided with bumper ring 1002, and bumper ring 1002 diameters are identical with the valve head diameter of the first spool 9, and the first spool 9 is when non-latching, and the valve head of the first spool 9 and bumper ring 1002 are fitted.
Speed in the time that fluid promotes the first spool 9 and moves downward under large pressure, the first spool 9 can clash into the second cylinder cap 10, and can wear and tear in the course of time the first spool 9 and the second cylinder cap 10 cause reduce its service life. So bumper ring 1002 is set in the second cylinder cap 10 inner sides, bumper ring 1001 diameters are identical with the valve head diameter of the first spool 9, now can be because of the existence of bumper ring 1002, and the first spool 9 can directly not contact with the second cylinder cap 10, avoid wearing and tearing, extended service life.
As Fig. 5, shown in Fig. 6, cylinder body 8 one sides are provided with the first buffering pipeline 802 and the second buffering pipeline 803, the first buffering pipeline 802 communicates with oil-in 801, the second buffering pipeline 803 communicates with the first spool 9 place pipelines, gas-liquid pressurizing type die cushion device also comprises valve plate 12, valve plate 12 comprises the first buffering pipe interface 1201 with the first buffering pipeline 802 adaptations, the second buffering pipe interface 1202 with the second buffering pipeline 803 adaptations, steel ball 1203, spring 1204, plug cock 1205 and the second spool 1206, the first buffering pipe interface 1201 is connected with the first buffering pipeline 802, the second buffering pipe interface 1202 is connected with the second buffering pipeline 803, the first buffering pipe interface 1201, plug cock 1205 and the second spool 1206 pass through pipeline connection, the second buffering pipe interface 1202 and plug cock 1205 pipeline connections, steel ball 1203 and spring 1204 are arranged in the pipeline that the first buffering pipe interface 1201 is communicated with plug cock 1205, by regulating plug cock 1205 to regulate the fluid flow between the second buffering pipe interface 1202 and the first buffering pipe interface 1201.
In the time of close port, be to adopt air inlet 1001 air inlets to promote the first spool 9 to move upward. Because air pressure is larger, can make the first spool 9 clash into fast the valve port of valve seat 7, easily cause the damage of the first spool 9 and valve seat 7. Now, at the outer access valve plate 12 of cylinder body 8, control first spool 9 rates of climb by plug cock 1205 on valve plate 12.
