Each reference numeral is：1 bar steel, 2 air bags, 3 tubing, 4 electromagnetic devices, 5 gas nozzles.
Specific embodiment
To better understand the objects, features and advantages of the present invention, with reference to specific embodiment pair
The present invention is described further.It should be noted that in the absence of conflict, the spy in embodiments herein and embodiment
Sign can be combined with each other.
Many details are elaborated in the following description to facilitate a thorough understanding of the present invention, still, the present invention may be used also
With using implementing different from other modes described here, therefore, the present invention is not limited to the specific of specification is described below
The limitation of embodiment.
Embodiment 1, as shown in Figure 1, the present embodiment provides a kind of concrete structure of differential method tubing radial drawing equipment, packet
Apparatus body is included, entire apparatus body is multi-lamellar structure, and the most inner side of apparatus body includes the cylindric air bag of closing
2, air bag 2, which can utilize, inflatable and deflatable realizes becoming larger and reducing for its aperture.2 one end of air bag be equipped with for air bag 2 into
The inflatable and deflatable gas nozzle 5 of row, gas nozzle 5 are deep by a hose inside air bag 2, and are provided with air-flow on hose and are cut
Only valve.In order to realize that the inflation of air bag 2 can generate expansion stresses, while can when expanding to the tubing for being located at 2 outside of air bag
It protects air bag 2 and can have enough hardness, polylith is uniformly fixed on 2 outer surface of air bag and is distributed along air bag 2 is axial
Bar steel 1.Bar steel 1 is the structure of strip, and more bar steels 1 are uniformly distributed along the surface of air bag 2 side by side.In apparatus body most
Outside is provided with cladding air bag 2 and the electromagnetic device 4 of bar steel 1, and the structure of electromagnetic device 4 is also that the electromagnet of more strips surrounds ring
Shape is corresponding setting with bar steel 1.3 placement location of tubing is in electromagnetic device 4 and between being coated on the bar steel 1 on 2 surface of air bag.
Electromagnetic device 4 can generate uniform gravitation after charging to bar steel 1, and the tubing 3 after heating is uniformly squeezed, thus by tubing
3 eliminate the internal stress of tubing while stretching.
In order to enable tubing 3 can uniform stressed, and reduce 1 usage amount of bar steel, so as to reduce the holistic cost of device,
1 thickness of bar steel on 2 surface of air bag is 3-10mm, width 0.5-1cm in the present embodiment, and the spacing between adjacent bar steel 1 is 10-
15mm.In order to preferably realize the interaction of electromagnetic device 4 and bar steel 1, the part charged later that is powered of electromagnetic device 4 is tubulose knot
