Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, every other embodiment that those of ordinary skill in the art are obtained all belongs to
In the scope of the utility model protection.
As shown in Figure 1-2, the new tube expander according to the utility model embodiment, including expander head connecting rod 1, institute
The inner side for stating expander 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；Institute
State to be arranged with expander head connecting rod 1 and be provided with air inlet 6, the expansion in the expander of elliposoidal first 3, the left end of the expander first 3
The right-hand member of tube head 3 is provided with gas outlet 7, passes through the expander first 3 and expander head connecting rod 1 between the air inlet 6 and gas outlet 7
Between air channel 11 be interconnected；The afterbody of the expander head connecting rod 1 is fixedly connected with some expanders being connected with each other
Steel wire 4, the inner side of the expander steel wire 4 are 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, for the expander first 3 in elliposoidal or spherical, the expander first 3 can be with expander head connecting rod
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
