Operation principle of the present utility model is as follows:
As shown in Figure 2, ventilation original state, sliding sleeve 27 is in the highest station; Enter the Compressed Gas of rifle body 31 from inlet suction port 44, by the switch assembly in opening, enter the valve passage top (being open and close valve 12 top cavitys) of cylinder head 5 through the right gas circuit of cylinder holder 16 and the cylinder head gas circuit of cylinder head 5 through the right gas circuit of gun barrel, Compressed Gas moves downward open and close valve 12, until the outer O type circle 14 of open and close valve 12 bottom faces contacts cylinder holder 16, thereby form sealing with the upper surface of cylinder holder 16;
Because Compressed Gas enters the die cavity 31-1 of rifle body 31, the pressure left that control valve assembly 16-1 is subject to is greater than pressure to the right, application valve body 22 is to left movement, the head of application valve body 22 stretches in the groove of sliding sleeve 27, and form sealing with the inclined-plane of cylinder holder 16, thereby left system gas circuit is closed.
As shown in Figure 3, in the time that switch lever 53 moves downward, switch lever 53 drives the gas in valve pocket 50 compression switch seat enclosure spaces that its pressure is increased, gases at high pressure in switch base enclosure space promote valve pocket 50 and move upward, and the gas circuit (being the gas channels between cylinder head gas circuit, the open and close valve 12 top cavitys of right gas circuit, cylinder head 5 of the right gas circuit of gun barrel, cylinder holder 16) of open and close valve 12 is communicated with the switch base gas circuit of leading to ambient atmosphere; The pressure left that now control valve assembly 16-1 is subject to is zero, is only subject to pressure to the right, and application valve body 22 moves right, thereby left system gas circuit is opened;
Compressed Gas in the die cavity 31-1 of rifle body 31 enters the bottom cavity of open and close valve 12 through the left gas circuit of gun barrel and the left gas circuit of cylinder holder, open and close valve 12 moves upward under the effect of Compressed Gas, forms sealing until open and close valve 12 top end faces contact with the open and close valve seal washer 6 of cylinder head 5; Now open and close valve 12 separates with cylinder holder 16, thereby the gas circuit of leading to cylinder 30 inner chambers is opened;
As shown in Figure 4, Compressed Gas enters the inner chamber of cylinder 30 from the top of piston assembly 28, and piston assembly 28 pressurizeds are moved downward, until the piston seat of piston assembly 28 contacts with cushion pad 32; Meanwhile, sliding sleeve 27 also moves downward under differential pressure action, until sliding sleeve 27 contacts with the interior step surface of cylinder 30, in minimum station;
In the process moving downward in piston assembly 28, the Compressed Gas of piston assembly 28 belows is discharged from steam vent 36-2.
As shown in Figure 5, switch lever 53 is unclamped by depressing to transfer to, gas circuit and the ambient atmosphere of open and close valve 12 are cut off, Compressed Gas enters open and close valve 12 top cavitys through the gas circuit of open and close valve 12, Compressed Gas moves downward open and close valve 12, until open and close valve 12 forms sealing with the upper surface of cylinder holder 16;
Now, because sliding sleeve 27 is still in minimum station, the head of application valve body 22 cannot stretch in the groove of sliding sleeve 27, and application valve body 22 cannot enter the most left station under the position-limiting action of sliding sleeve 27, therefore can the left gas circuit of keeping system unimpeded; Compressed Gas is in entering open and close valve 12 top cavitys through the gas circuit of open and close valve 12, enter the piston seat below of piston assembly 28 downwards and enter the cavity of nail-head component 38 through the exhaust gas circuit of nail-head component 38 through the left gas circuit of gun barrel from the left gas circuit of cylinder holder 16, as shown in Figure 6; The Compressed Gas that enters the piston seat below of piston assembly 28 moves upward piston assembly 28; Enter the Compressed Gas of nail-head component 38 cavitys by the upwards jack-up of exhaust axle sleeve 36 in cavity, exhaust axle sleeve 36 cuts out steam vent 36-2, thereby cylinder 30 bottoms is passed through to the pathway closure of nail-head component 38 and ambient atmosphere;
As shown in Figure 7, when moving up under the effect of piston assembly 28 at Compressed Gas while contacting with sliding sleeve 27, Compressed Gas promotes sliding sleeve 27 simultaneously and together moves upward;
As shown in Figure 8, in the time that sliding sleeve 27 moves to the highest station, sliding sleeve 27 is removed the position-limiting action of application valve body 22, and application valve body 22 can, to left movement, until the head of application valve body 22 stretches in the groove of sliding sleeve 27, close the left gas circuit of system; Now piston assembly 28 and sliding sleeve 27 are all realized reset;
As shown in Figure 9, because the left gas circuit of system is closed, the Compressed Gas that enters nail-head component 38 cavitys is cut off, exhaust axle sleeve 36 moves downward under the effect of exhaust stage clip 36-1, exhaust axle sleeve 36 cuts out steam vent 36-2, thereby cylinder 30 bottoms are opened by nail-head component 38 and the passage of ambient atmosphere, the Compressed Gas that is stored in cylinder 30 inner chambers is discharged by this passage, so far complete a working cycles.
