The utility model comprises gripper shoe, limiting plate, left end cap, stator case, moving vane, right end cap, steel ball, rotor, back-up ring, cutter shaft, hobboing cutter, flat strong, fixed blade, rotor bearing and sealing ring, left end cap and right end cap are separately fixed at the both sides of stator case, fixed blade is fixed on the stator case, moving vane is fixed on the rotor, and all be provided with sealing ring, rotor is arranged on the end cap endoporus of the left and right sides by rotor bearing, gripper shoe is by the flat strong both sides that are separately positioned on rotor inner hole, cutter shaft is arranged in the gripper shoe helicla flute of both sides, the two ends of cutter shaft are provided with limiting plate and steel ball, and by back-up ring, pad and collar are fixed, hobboing cutter is arranged on the cutter shaft, and fix by hob sleeve, described gripper shoe is provided with three sections helicla flutes of symmetrical distribution, and described limiting plate is provided with the microscler chute hole of 3 symmetries.
The utlity model has compact conformation, in light weight, Roll-turning tool is many, production efficiency is high, chipless process, rotary inertia are little, low noise, cost is low and the easy advantages such as adjustment of rolling cut power and rolling cut speed.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the utility model limiting plate structural representation;
Among the figure: 1 gripper shoe, 2 limiting plates, 3 left end caps, 4 stator cases, 5 moving vanes, 6 right end caps, 7 steel balls, 8 rotors, 9 back-up rings, 10 cutter shafts, 11 hobboing cutters, 12 flat keys, 13 fixed blades, 14 rotor bearings, 15 sealing rings.
The specific embodiment
Further specify organization plan of the present utility model and operation principle below in conjunction with example.
As shown in the figure, a kind of air-operated swing slitting mill comprises gripper shoe 1, limiting plate 2, left end cap 3, stator case 4, moving vane 5, right end cap 6, steel ball 7, rotor 8, back-up ring 9, cutter shaft 10, hobboing cutter 11, flat key 12, fixed blade 13, rotor bearing 14 and sealing ring 15.Stator case 4 is a Welding Structure, and left end cap 3 and right end cap 6 are separately fixed at the both sides of stator case 4 by bolt.Fixed blade 13 is screwed on stator case 4, and is provided with sealing ring 15.The both sides of fixed blade 13 are respectively equipped with passage.Moving vane 5 is screwed on rotor 8, and is provided with the sealing ring same with sealing ring 15.The two ends of rotor 8 cylindricals are arranged on the endoporus of left and right sides end cap 3 and 6 by needle-type rotor bearing 14, and seal with dust ring, and the endoporus of rotor 8 is a through hole.2 gripper shoes 1 are separately fixed at the both sides of rotor 8 endoporus by flat key 12.As shown in Figure 2,2 gripper shoes 1 are provided with three sections helicla flutes of symmetrical distribution, can adjust rolling cut power by changing the helicla flute pressure angle, and 3 cutter shafts 10 are separately positioned in three sections helicla flutes of supported on both sides plate 1.The two ends of cutter shaft 10 are respectively arranged with limiting plate 2 and steel ball 7, and steel ball 7 is arranged between gripper shoe 1 and the limiting plate 2, and are fixed by back-up ring, pad and collar, are respectively arranged with hobboing cutter 11 on the cutter shaft 10, and are fixed by hob sleeve.As shown in Figure 3, limiting plate 2 is provided with the microscler chute hole of 3 symmetries.
A kind of operation principle of air-operated swing slitting mill: rotary actuator is single vane type, and rotor is a through-hole structure, and hard-over is 300 °, and tubing passes the rotor through hole, and 3 hobboing cutters are made radial displacement roll extrusion incising pipes.As shown in the figure, rolling cut is initial, gas motor moving vane 5 is near the left side of fixed blade 13, motor left side bottom outlet is an air admission hole, the right side bottom outlet is a steam vent, moving vane 5 drives rotors 8 turn clockwise (swing), 3 cutter shafts 10 are respectively under the common restriction of limiting plate 2 and gripper shoe 1,3 cutter shafts 10 lay respectively at the top of gripper shoe 1 helicla flute and limiting plate 2 chutes, when rotor drive gripper shoe 1 turns clockwise, under the effect of helicla flute pressure angle, cutter shaft 10 forces hobboing cutter 11 to produce radial displacement along the helicla flute retraction, when contacting by Pipe Cutting material external diameter, 3 cutter shafts 10 are along helicla flute scroll-diced tubing, and cut darker and darker, and tubing is cut off when cutter shaft 10 arrives the spiral fluted other ends.Pendulum cuts complete, the gas circuit commutation, and gas motor moving vane 5 is rotated counterclockwise, and cutter shaft 10 is return along gripper shoe 1 helicla flute fast, until initial position.The effect of limiting plate 2 is mutual alignments of restriction cutter shaft 10, guarantees that cutter shaft 10 is positioned at the initial position (top of spiral indent) of rolling cut when shutting down, and it also can relatively rotate gripper shoe 1 around central shaft.
