Air-channel system of the present invention mainly completes the pressurization after quick return, precompressed and precompressed, and its combining form can have a variety of, provides now following a kind of embodiment:
As shown in Figure 2, described air-channel system comprises two-position five-way valve 22 and two position three-way valve 24, three interfaces of described two-position five-way valve 22 are communicated with backhaul gas-entered passageway 20, fast gas-entered passageway 12 and source of the gas respectively by pipeline, all the other interfaces of two-position five-way valve 22 are communicated with air, described two-position five-way valve 22 has two kinds of seats in the plane, one is that source of the gas is communicated with backhaul gas-entered passageway 20 and fast gas-entered passageway 12 is communicated with air, and another kind is that source of the gas is communicated with quick gas-entered passageway 12 and backhaul gas-entered passageway 20 is communicated with air, the interface of described two position three-way valve 24 by pipeline respectively with quick gas-entered passageway 12, super charge passage 2 and air are communicated with, described two position three-way valve 24 has two kinds of seats in the plane, one is that quick gas-entered passageway 12 is communicated with super charge passage 2, another kind is that super charge passage 2 is communicated with air, backhaul gas-entered passageway 20 and fast gas-entered passageway 12 are connected with the control end of two position three-way valve 24 respectively by pipeline, the pipeline that described backhaul gas-entered passageway 20 is connected with the control end of two position three-way valve 24 is provided with one-way throttle valve 23(for preventing the excessive device damage caused of bypass pressure).
Job step of the present invention is:
1) prepare stroke: the seat in the plane of two-position five-way valve 22 is that source of the gas is communicated with backhaul gas-entered passageway 20 and gas-entered passageway 12 is communicated with air fast, source gas is led to by two-position five-way valve 22 and enters backhaul gas-entered passageway 20, and working piston 14 is stabilized in initial position.Gas in the gas-entered passageway of backhaul simultaneously 20 is bypassed to the control end of two position three-way valve 24, and super charge passage 2 is communicated with air.
2) F.F. stroke: the seat in the plane of two-position five-way valve 22 is that source of the gas is communicated with quick gas-entered passageway 12 and backhaul gas-entered passageway 20 is communicated with air, source gas pushes the work forward piston 14 until working beam 11 contacts part to be processed, and the gas simultaneously in quick gas-entered passageway 12 arrives interface and the control end of two position three-way valve 24 by pipeline.
3) reinforcement stroke; After working beam 11 touches processing accessories, clutch release slave cylinder cylinder body 16 internal volume is constant, air pressure inside levels off to source of the gas air pressure very soon, now two position three-way valve 24 switches seat in the plane, quick gas-entered passageway 12 is communicated with super charge passage 2, gas in quick gas-entered passageway 12 enters super charge passage 2, and charged piston 3 is pressed down the object reaching supercharging.
4) return stroke: super charge passage 2 is communicated with air, source of the gas is communicated with backhaul gas-entered passageway 20 and gas-entered passageway 12 is communicated with air fast, source gas enters from backhaul gas-entered passageway 20 and makes work plug bar alive get back to initial position, and Returnning spring 4 makes charged piston 3 return initial position.
As shown in figures 1 and 3, middle cover 18 is provided with in the middle part of described clutch release slave cylinder cylinder body 16, gap is there is between middle cover 18 inwall and working beam 11, described working beam 11 outer wall is provided with a circle step 15, when working beam 11 moved a certain position, step 15 and middle cover 18 are sealed and matched, middle cover 18 is provided with venting channels 17, the both ends open of venting channels 17 is located at the both sides of middle cover 18 respectively, one-way valve 21 is provided with in venting channels 17, in venting channels 17, gas can flow to the opening A near front cover 19 from the opening B near rear end cover 1, oppositely end.
When the step 15 on middle cover 18 with working beam 11 is sealed and matched, the both sides of the inner middle cover of clutch release slave cylinder cylinder body 16 18 are mutually isolated, now, under the effect of one-way valve 21, gas can only enter the side A near front cover 19 from the side B near rear end cover 1, if when now carrying out backhaul operation, just start the step 15 that gas can only push the work forward on bar 11 to move, until step 15 exits middle cover 18, middle cover 18 both sides UNICOM again, gas could promote whole working piston 14, when gas only promote step 15 until middle cover 18 two ends UNICOM time, because gas and working piston 14 area of contact expand instantaneously, working beam 11 is made to impact backhaul, opening speed is faster.Working beam 11 is arranged step 15 and not only can play effective sealing effect but also can workpiece be protected, prevent damage workpiece caused because of working beam 11 quick return.As shown in Figure 1 and Figure 4, the import E of described feed pathway 9 is located at the outer wall of airdraulic actuator conversion middle cover 8, outlet is located on two sidewalls of airdraulic actuator conversion middle cover 8 respectively, one-way valve 21 is provided with in feed pathway 9, in feed pathway 9, liquid can flow to a side outlet C of close front cover 19 from the outlet D near rear end cover 1 side, oppositely end.
When booster rod 6 opening speed is too fast, can in oil hydraulic cylinder and gas-liquid conversion middle cover 18, produce negative pressure and damage seal ring, long this easily causes leakage or working beam 11 to get unable problem, gas-liquid conversion middle cover 18 arranges one-way valve 21, fluid can only flow to the side C near front cover 19 from the side D near rear end cover 1, when the through hole that booster rod 6 and gas-liquid change middle cover 18 is sealed and matched, gas-liquid sealing block 7 and gas-liquid change the closed chamber being formed between middle cover 18 and be full of liquid, now, when booster rod 6 quick return, former hydraulic cylinder body 10 internal liquid pressure will sharply reduce, when be reduced to pressure and gas-liquid change fluid pressure between middle cover 18 and gas-liquid sealing block 7 identical after will reduce to form negative pressure, liquid can flow to pressure sharply reduction place by one-way valve, prevent the formation of negative pressure.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improve and convert the protection domain that all should belong to claims of the present invention.
