Problems solved by technology

[0004] 1. In order to maintain the pressure state of the support fluid 3 in the square tube 1, the pressure adjustment device 2 must be additionally installed on the square tube 1. This is not only troublesome, but also may cause the clamp to clamp and rotate the square tube 1. inconvenient
[0005] 2. This method is to use the support fluid 3 to fill the inside of the square pipe 1. Therefore, in order to maintain the pressure state

Abstract

The metal pipe twisting formation process includes the following steps: A. preparing one metal pipe with one first locating section, one second locating section and one pre-twisted section in between, and one reinforcing part with cross section shape corresponding to that of the inner holes of the first locating section and the second locating section and length greater than that of the pre-twisted section; B. setting the reinforcing part inside the inner hole of the pre-twisted section with two ends of the reinforcing part stretched into the inner holes of the first locating section and the second locating section separately; and C. twisting the first locating section and the second locating section relatively to make the pre-twisted section form one twisting structure along the axis. The present invention has simple process, no influence on the support and rotation of fixture and no leakage.

Description

【Technical field】 [0001] The invention relates to a forming method, in particular to a hollow metal tube twist forming method with simple steps. 【Background technique】 [0002] Such as figure 1 , 2 , shown in 3, is the manufacturing method of existing a kind of hollow square pipe rotating structure, and its steps are: one, prepare a hollow square pipe 1; On an open end of the tube 1; 3. A support fluid 3 is filled in the square tube 1 through the pressure adjustment device 2, and the support fluid 3 in the square tube 1 is maintained at a high pressure by the pressure adjustment device 2 4. Clamp the square tube 21 at the predetermined position with a clamp (not shown in the figure), and rotate the clamp to force the square tube 21 to deform, and form a rotating structure 101 on the predetermined surface; and 5. Use the pressure adjusting device 2 to release the supporting fluid 3 in the square tube 1 . [0003] Although, in the above-mentioned manufacturing method, duri...
