Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Referring to FIG. 1-2, the present invention provides a kind of carbon fibre composite air dispersion device, including fixture nut 1,
The side of the internal screw thread of fixture nut 1 and 3 outer wall of fixed hub is carved the external screw thread set and is threadedly coupled, 3 outer wall of fixed hub it is another
The inner wall of side and pressure spring 4 is socketed, and one end of pressure spring 4 is fixedly connected with one end of 2 inner wall of flower pattern end cap.
The preparation process of composite polymer material used in 1 fixture nut of embodiment, flower pattern end cap and fixed hub is as follows:
Weigh following raw materials:
Polyvinyl chloride resin 50kg；Carbon fiber 40kg；Ethylene propylene diene rubber 20kg；Diamond dust 10kg；Two alkali formula aluminium phosphite 3kg；
Three basic aluminium sulphate 2kg；Calcium carbonate 8kg；Stearic acid 4kg；Barium sulfate 7kg；Salicylic acid 7kg；Nylon fiber 20kg；Carbon black 8kg.
Ethylene propylene diene rubber is added in open mill, temperature controls at 50 DEG C or so, carbon black is added, is stirred evenly, will
Remaining raw material in addition to diamond dust is added, and after being kneaded uniformly, finally diamond dust is added, and after being kneaded uniformly, slice is cooled to
Room temperature；It is granulated and is crushed to get of the invention for manufacturing the material of fixture nut, flower pattern end cap and fixed hub in crusher；
By above-mentioned material single screw-type extruder extrusion molding, temperature section is controlled, using feed inlet as sequence, extrusion forming；Through bore
Sizing；It is cooling；Traction；Fixture nut, flower pattern end cap and fixed hub is made in scale respectively.
Preferably, one end of fixture nut 1 is connected to the fixation of one end of casing 7, outside the inner wall and fixed hub 3 of casing 7
The interspersed connection in the middle part of wall, can protect fixed hub 3.
Preferably, the other end of fixture nut 1 is fixedly installed with air-dispersing part 5, is convenient for air-dispersing.
Preferably, the middle part on 1 top of fixture nut and the middle part of bottom end are fixed with nut handle 6, convenient for fixed spiral shell
Mother's 1 turns.
Preferably, fixture nut 1, flower pattern end cap 2 and fixed hub 3 are made of composite polymer material, and dress can be improved
The service life set and stability.
When specifically used, a kind of carbon fibre composite air dispersion device of the present invention, can according to practical application scene into
It exercises and uses, the end position of air dispersion device will be mounted on from breathing telescoping mechanism, with gas passage and gas cutting part
It fits, the threaded connection screw-in length of fixed hub 3 Yu fixture nut 1, the difference of screw-in length is freely adjusted in assembling
Cause the active force of pressure spring 4 different, pressure spring 4 acts on flower pattern end cap 2, thus can set the initial pressure to flower pattern end cap 2, when
