Working principle:
Because 90% of the crust breaking cylinder stroke of electrolytic aluminium groove is to do the no load movement of F.F..Can consider the pressurized air supply back cavity of cylinder ante-chamber in the F.F. process is realized energy-conservation requirement; Control principle is as shown in Figure 3; During use gas source is connected with the P1 mouth of two-position five-way Pneumatic valve 21; The B1 mouth of two-position five-way Pneumatic valve 21 leads to cylinder 22 back cavities; The A1 mouth of two-position five-way Pneumatic valve 21 through the container type bonnet of cylinder 22 lead to the suction port P mouth 25 (promptly communicating) of solar term pneumatic valve of the present invention with P chamber 30, the working hole A mouth 24 of solar term pneumatic valve is connected to the ante-chamber of cylinder 22 (promptly communicating with active chamber A chamber 31), and the relief opening O mouth 23 of solar term pneumatic valve is connected to the B1 mouth (promptly communicating 29 with the O chamber) of two-position five-way Pneumatic valve 21 through the hole path in the bonnet of cylinder 22.
Position as shown in Figure 3; When gas source P1 confession gas; Because cylinder 22 front and back two chamber lifting surface areas are different; Stretch out motion so cylinder piston rod is done, the working hole A mouth 24 of ante-chamber pressurized air through air throttle with relief opening O mouth 23 supply that communicates give the back cavity (this moment, the air throttle present position was as shown in Figure 1) of cylinder 22.When piston rod touches workpiece; Load decision pressure size; Cylinder 22 ante-chambers rise to press and cause air throttle active chamber A chamber 31 pressure to raise, and the control channel 20 of active chamber A chamber 31 pressure below valve body arrives the chamber 26, a loam cake left side in control pistons 4 left sides, overcome spring 5 pressure on control piston 4 right sides when control piston 4 left side pressure after; Control piston 4 moves right and causes air throttle piston 7 drive valve rods 11 to move right; Make the O chamber 29 of air throttle not connected under the effect of E shape circle 12 with active chamber A chamber 31, and A chamber 31 and 30 intercommunications of P chamber, promptly working hole A mouth 24 communicates with suction port P mouth 25; This moment, cylinder 22 ante-chamber pressurized air just can be arranged to atmosphere through the A1 mouth of two five-way Pneumatic valves 21, and cylinder is gone to end of travel and accomplished crust breaking work; After switch valve with two-position and five-pass 21 switching-overs; The suction port P mouth 25 of air throttle passes through the A1 confession pressurized air of two-position five-way Pneumatic valve 21, and commutates moment at two-position five-way Pneumatic valve 21, and air throttle P chamber 30, active chamber A chamber 31 and O chamber 29 all do not have pressure; Control piston 4 under the effect of spring 15 power between valve rod 11 and the screw plug 14, reset (getting back to position shown in Figure 1) then; After two-position five-way Pneumatic valve 21 was accomplished switching-over, air throttle P mouth 25 is connected with source of the gas caused P chamber 30 pressure to raise, and gas arrives the chamber 28, a valve body left side in piston 7 left sides through the control channel above the air throttle P chamber 30 20; Because the power of spring 15 is very little; So valve body inner carrier 7 drives valve rod 11 and moves right, thereby make the O chamber 29 of air throttle and active chamber A chamber 31 not connected under the effect of E shape circle 12, and P chamber 30 communicate with 31 chambeies, active chamber A chamber; The P mouth 25 that is air throttle communicates with A mouth 24; Gas can be through this path to cylinder 22 ante-chamber air feed, and the gas of cylinder 22 back cavities is then arranged to atmosphere from the B1 mouth of switch valve with two-position and five-pass 21, and cylinder can normally be withdrawn.When the P of air throttle mouth 25 no pressure, i.e. P chamber 30 no pressure, piston 7 are got back to initial position (position shown in Figure 1) execution circulation under the effect of spring 15 power.This manner of execution can make the pressurized air between two chambeies of cylinder complementary in the unloaded movement speed of accelerating crust breaking cylinder, thereby realizes energy complement between two chambeies, reaches energy-saving effect.Simultaneously can make the pneumatic control system stable working again, reliability is high.
Above-mentionedly being merely part technological scheme instance of the present invention, is not to be used for limiting scope of the present invention, and equivalent variations and modification that promptly all foundations claim of the present invention is done are the scope in the technological scheme of the present invention.
