compress tightly subassembly 31, compress tightly subassembly 31 and set up in one side of spacing subassembly 30, compress tightly subassembly 31 and be used for compressing tightly fixed work to the amortization pipe fitting after finishing adjusting spacing regulation.

Specifically, before need carrying out the sizing to the amortization pipe fitting staff place the amortization pipe fitting in spacing subassembly 30's output at first, carry out spacing and preliminary fixed work to the amortization pipe fitting through spacing subassembly 30, fixed back staff that finishes compresses tightly subassembly 31 work at the drive, compresses tightly the vertical decline of subassembly 31 output and pushes down to amortization pipe fitting outer wall to the realization is to the fixed work that compresses tightly of amortization pipe fitting.

Further, as shown in fig. 11 and 12:

the limiting assembly 30 comprises a first supporting frame 32, the first supporting frame 32 is arranged on the rack 1, a U-shaped material returning plate 33 is further arranged on one side, facing the sizing device 3, of the first supporting frame 32, and buffer cotton 34 is further arranged on the surface of the U-shaped material returning plate 33;

the limiting table 35 is arranged on the first support frame 32 in a sliding manner;

drive actuating cylinder 36, drive actuating cylinder 36 fixed mounting in the one end of first support frame 32, the output that drives actuating cylinder 36 passes first support frame 32 and sets up towards spacing platform 35, drives actuating cylinder 36's output and spacing platform 35 fixed connection.

Concretely, under the operating condition at first place the amortization pipe fitting on spacing platform 35, for the convenience of staff places work to the amortization pipe fitting more fast, place preceding actuating cylinder 36 and can drive output end fixed connection's spacing platform 35 and contract backward to the amortization pipe fitting, make spacing platform 35 keep away from sizing device 3 setting, so that the staff is easier, the quick longer amortization pipe fitting of placing is as for spacing platform 35 on, the amortization pipe fitting is placed and is finished back actuating cylinder 36 and promote spacing platform 35 and reset, U-shaped material returned plate 33 is used for retracting at spacing platform 35 when blowing once more, amortization pipe fitting after finishing the sizing pulls away from spacing platform 35 through U-shaped material returned plate 33, realize the quick unloading work of amortization pipe fitting after finishing the sizing.

Further, as shown in fig. 12, 13, 14, and 15:

the limiting table 35 is rectangular and long, an arc-shaped groove 37 for placing a silencing pipe fitting is further formed in the surface of the limiting table 35, and a pair of second sliding grooves 38 which are arranged on two sides of the arc-shaped groove 37 in a mirror image state are further formed in the surface of the limiting table 35;

the inner supporting rod 39 is coaxially arranged with the arc-shaped groove 37, the diameter of the inner supporting rod 39 is smaller than the inner diameter of the arc-shaped groove 37, and one end of the inner supporting rod 39 is fixedly connected with the limiting table 35;

the adjusting block 40 is arranged on the outer wall of the inner support rod 39 in a sliding fit mode, the adjusting block 40 is connected with the second sliding groove 38 in a sliding mode through second sliding strips 41 fixedly arranged on two sides, and the adjusting device further comprises a locking bolt 42 arranged on one side of the adjusting block 40 and used for locking the adjusting block 40 after adjustment is completed.

Concretely, before need carries out the sizing to the amortization pipe fitting, at first according to the length adjustment of required sizing good regulating block 40 to the length between the spacing platform 35 tip, make needs sized pipe fitting can just take over outside spacing platform 35, adjust and finish the back and lock the regulating block 40 fixedly through locking bolt 42, then with amortization pipe fitting plug bush outside interior vaulting pole 39, and with amortization pipe fitting orientation regulating block 40 direction propelling movement, the tip of amortization pipe fitting is contradicted and is stopped after regulating block 40, then compress tightly the amortization pipe fitting through compressing tightly subassembly 31, realize the sizing work to the amortization pipe fitting tip through sizing subassembly 4 at last.

Further, in order to solve the technical problem of compressing the sound pipe, as shown in fig. 11, the following technical solutions are provided:

the pressing device comprises a second supporting frame 43, and the second supporting frame 43 is arranged on one side of the limiting assembly 30;

the hydraulic cylinder 44 is fixedly arranged at the top end of the second support frame 43, and the output end of the hydraulic cylinder 44 penetrates through the second support frame 43 and is arranged towards the limiting assembly 30;

the pressing block 45 is fixedly installed at the output end of the hydraulic cylinder 44, the pressing block 45 is arc-shaped and long, and protective cotton 46 is further attached to the pressing surface of the pressing block 45.

Concretely, after the amortization pipe fitting is placed and is accomplished, drive hydraulic cylinder 44 work, hydraulic cylinder 44 output extends and drives compact heap 45 and be close to towards the amortization pipe fitting, stops until compressing tightly behind the amortization pipe fitting outer wall to accomplish the fixed work that compresses tightly to the amortization pipe fitting, protection cotton 46 is used for compressing tightly to the amortization pipe fitting rear protection amortization pipe fitting at compact heap 45, avoids the amortization pipe fitting outer wall to appear crushing.

The positioning, limiting and fixing device realizes the positioning, limiting and fixing work of the silencing pipe fitting to be sized through the fixing device 2, and realizes the sizing work of the silencing pipe fitting after the fixing is finished through the matching of the first linear driver 6 and the sizing component 4.
