Its operation principle is: Figure 1 shows that original state, open magnetic valve 2, A, P mouth of magnetic valve 2 is communicated with, secondary venthole 26 is communicated with secondary outlet passageway 25, depositing air cavity 21 provides lasting nailing source of the gas P1(to see in Fig. 1 shown in A arrow to air inlet 59), and the nailing source of the gas P1 inlet chamber 12(that simultaneously enters gland 1 to be shown in Fig. 1 shown in B arrow).
Owing to being provided with spring 82 between pressure ring 81 and gland piston 83, and, gland piston 83 is greater than gland piston 83 towards the area of inlet chamber 12 and is communicated with air inlet 59 towards the first air storing cavity 54(first air storing cavity 54) area, so, when switch 2 is opened, gland piston 83 moves downward channel enclosed between cylinder head and the first air storing cavity 54, a certain amount of compressed air is stored in first air storing cavity 54, simultaneously, the blast pipe 831 of gland piston 83 does not contact with sealing gasket 11, blast pipe 831 is communicated with exhaust passage 13 (blast pipe 831 is communicated with air), meanwhile, rifle pin piston 9 is in top and gland piston 83 is sealed and matched.
Shown in Figure 2, when shut electromagnetic valve 2, the O of magnetic valve 2, A mouth is communicated with (A, P mouth is no longer communicated with), the source of the gas entering inlet channel 14 cuts off, source of the gas P1 only enters the first air storing cavity 54, in inlet channel 14, pressure loses, gland piston 83 moves upward, blast pipe 831 contacts with sealing gasket 11, blast pipe 831 is not communicated with exhaust passage 13, simultaneously, first air storing cavity 54 is communicated with cylinder top, other abrupt release of compression in first air storing cavity 54, and nailing source of the gas P1 constantly supplements, nailing source of the gas P1 enters along the A direction of arrow in Fig. 2 from cylinder top, promotion rifle pin piston 9 and rifle pin 6 move to rifle mouth 7 direction, to see in Fig. 2 shown in F arrow.
Shown in Figure 3, when the first sealing ring 91 of the buffer head 92 of rifle pin piston 9 enters into air cushion buffering stepped hole 56, buffer head 92 upper end is cushioned stepped hole 56 inner wall sealing by the first sealing ring 91 with air cushion and is coordinated, buffer head 92 lower end is coordinated with bushing 57 inner wall sealings by the second sealing ring 93, buffer head 92 and air cushion are cushioned jointly to surround between stepped hole 56 closed interval (see in Fig. 3 shown in C arrow, be air cushion), when rifle pin piston 9 continue descending realize nailing time, air cushion is compressed further, thus repulsive force is produced to rifle pin piston 9, rifle pin piston 9 lower end is avoided to collide with buffering aligning glue 58, thus available protecting rifle pin piston 9 and buffering aligning glue 58.
Meanwhile, the piston packing H of rifle pin piston 9 outside is between cylinder intake hole 41 and relief hole 42, and source of the gas P1 enters in the second air storing cavity 55 along the A direction of arrow, and source of the gas P1 compresses at the second air storing cavity 55.
Shown in Figure 4, when needs rifle pin piston 9 resets, again open magnetic valve 2, gland piston 83 resets, return to Fig. 1 state, communicating with air cylinder inner cavity moment above rifle pin piston 9, (the cylinder inner cavity air G above rifle pin piston 9 discharges from exhaust passage 13, pressure reduces instantaneously), now, in second air storing cavity 55, the air D of compression discharges fast from relief hole 42 in the early time, air D to be introduced between rifle pin piston 9 and buffer head 92 necking down position 94(due to necking down position 94 and rifle pin piston 9 conical surface transition, namely on the upside of necking down position 94, area is larger), simultaneously, in air cushion buffering stepped hole 56, compressed air discharges simultaneously, rifle pin piston 9 fast uplink is resetted, and drive rifle pin 6 to reset (see T arrow in Fig. 4 Suo Shi).And air cushion buffering stepped hole 56 is opened rapid exhaust, immediately heat is taken out of, even also has the effect of Local cooling.
As embodiment more specifically, the described body of a gun 5 is also provided with oil-in 52, and oil-in 52 one end is communicated with the second air storing cavity 55, and oil-in 52 other end is provided with fuel feed pump 3, and fuel feed pump 3 is provided with check valve 31.Shown in Figure 4, when in the second air storing cavity 55, pressure is less than charge oil pressure, and when charge oil pressure is greater than check valve 31, check valve 31 is opened, and lubricating oil E enters cylinder inner cavity, provides lubrication to rifle head internal moving parts.And being furnished with sufficient lubricating status, effectively reduce frictional force, the heat energy produced by frictional force is also able to straight line and declines, the same straight line of the degree of wear of rifle pin piston 9 declines.Specifically, when air cushion buffering structure to combine with rifle head lubrication system use time, first sealing ring 91 and the second sealing ring 93 obtain good lubrication for a long time, reduce coefficient of friction during its motion, simultaneously, the damaging heat produced when reducing its friction, to improve the service life of the first sealing ring 91 and the second sealing ring 93, guarantees form the air cushion effectively playing cushioning effect between cylinder body 4 and rifle nozzle assembly.
