Embodiment
The utility model is described in further detail below in conjunction with concrete accompanying drawing.
As Fig. 1～shown in Figure 4: as described in blow cylinder comprise signal chamber 1, protecgulum 2, joint 3, left chamber 4, tracheae 5, cylinder barrel 6, piston 7, accumulation of energy chamber 8, middle cover 9, signal tube 10, piston rod 11, seal ring 12, two-position five-way Pneumatic valve 13, bonnet 14, first gas port 15, second gas port 16 etc.
As shown in Figure 1 and Figure 2, the utility model comprises cylinder barrel 6, in the front end and back end of cylinder barrel 6 protecgulum 2 and bonnet 14 is set respectively, is provided with joint 3 at protecgulum 2, and joint 3 is provided with first gas port 15, is provided with second gas port 16 at bonnet 14; In described cylinder barrel 6 inside middle cover 9 is set, middle cover 9 is separated into left chamber 4 and accumulation of energy chamber 8 with the inner chamber of cylinder barrel 6, is provided with through hole at middle cover 9 middle parts, and piston rod 11 is set in through hole, and protecgulum 2 is stretched out in the end of piston rod 11, and fixed piston 7 on piston rod 11; As shown in Figure 1, the through-hole wall at described middle cover 9 middle parts is provided with cell body, and seal ring 12 is set in cell body, the motion that seal ring 12 can limited piston bar 11;
As shown in Figure 1 and Figure 2, two-position five-way Pneumatic valve 13 is installed in described bonnet 14, first working hole of two-position five-way Pneumatic valve 13 is connected with first gas port 15 by tracheae 5, first gas port 15 is communicated with left chamber 4, second working hole is connected with second gas port 16, and second gas port 16 is communicated with accumulation of energy chamber 8;
As shown in Figure 1 and Figure 2, the chamber between described middle cover 9 and the piston 7 is signal chamber 1, is connected signal tube 10 between signal chamber 1 and two-position five-way valve 13.
Working procedure of the present utility model: the utility model is being the energy with pressurized air, pressurized air is by the suction port air inlet that is installed in the two-position five-way Pneumatic valve 13 in the bonnet 14, enter second gas port 16 by second working hole again, enter accumulation of energy chamber 8, the 8 beginning accumulation of energys of accumulation of energy chamber, piston rod 11 is subjected to the resistance limits of seal ring 12, slowly motion; Accumulation of energy chamber 8 energy strengthen fast, when piston rod 11 and seal ring 12 disengagings, and the 8 energy abrupt releases of accumulation of energy chamber, piston rod 11 stretches out fast, produces bigger impact force;
