Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained belongs to present invention protection
Scope.
As shown in Figure 1-2, new tube expander described according to embodiments of the present invention, including expander head connecting rod 1, the expansion
The inner side of tube head connecting rod 1 is provided with the first oil circuit 10, and the head of the expander head connecting rod 1 is provided with some nozzle openings 2；The expansion
It is arranged with tube head connecting rod 1 in the expander of elliposoidal first 3, the left end of the expander first 3 is provided with air inlet 6, the expander first 3
Right-hand member be provided with gas outlet 7, by between the expander first 3 and expander head connecting rod 1 between the air inlet 6 and gas outlet 7
Air channel 11 be interconnected；The afterbody of the expander head connecting rod 1 is fixedly connected with some expander steel wires being connected with each other
4, the inner side of the expander steel wire 4 is provided with the second oil circuit 5 being connected with first oil circuit 10.
Wherein, the head of the expander head connecting rod 1 is tapered.Wherein, the air inlet 6 is curved.Wherein, it is described go out
Gas port 7 is curved.Wherein, in elliposoidal, or spherical, the expander first 3 can be with expander head connecting rod for the expander first 3
Axle is rotated centered on 1.Wherein, the external diameter of the expander first 3 is more than the internal diameter of pipe fitting 8, the head of expander head connecting rod
The external diameter of external diameter and expander steel wire.Wherein, the expander first 3 is wear-resistant alloy.Wherein, some expander steel wires 4
Between be connected with each other by expander steel wire connecting rod 9, the inner side of the expander steel wire connecting rod 9 is provided with the second oil circuit 5 described in.
Understand above-mentioned technical proposal of the invention for convenience, below by way of in specifically used mode to of the invention above-mentioned
