Embodiment Construction
[0015] In the following, the present invention will be further described in conjunction with the accompanying drawings and specific embodiments, so as to understand more clearly the technical idea claimed in the present invention.
[0016] like figure 2 Shown the processing technology of a kind of special-shaped stainless steel pipe of the present invention, comprises the following steps:
[0017] a. Straight round tube forming, the stainless steel plate is processed and formed into a straight round tube shape according to requirements by a pipe welding machine;
[0018] b, length interception, the straight round tube formed in step a is cut out to the required length according to production needs;
[0019] c, the tapered pipe portion is formed, and the tapered pipe portion 2 is formed by shrinking the two ends of the straight round pipe of the length cut in step b by a pipe shrinking machine;
[0020] d. Forming the square pipe part. The middle part of the straight round p...

The invention discloses a machining process for a special-shaped stainless steel tube. The machining process sequentially comprises the steps of straight round tube forming, tube cutting according to lengths, conical tube part forming, square tube part forming and the like. A stainless steel plate is formed into a straight round tube through a tube welder, then the straight round tube is cut to be in the required length according to the requirement, the two ends of the cut straight round tube are subjected to necking-down machining treatment through a tube contracting machine and formed into conical tube parts, and the middle of the straight round tube with the two ends being formed into the conical tube parts is subjected to square compressing treatment and formed into a square tube part through a square compressing machine. The process has the characteristics that the square tube part in the middle and the conical tube parts at the two ends of the special-shaped stainless steel tube can be machined and formed integrally, and the strength of a special-shaped stainless steel tube structure can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of processing and forming of stainless steel pipes, in particular to a processing technology of special-shaped stainless steel pipes. Background technique [0002] as attached figure 1 The special-shaped stainless steel pipe shown includes a square pipe part 1 in the middle and tapered pipe parts 2 at both ends. The traditional method of forming the special-shaped stainless steel pipe is: first process and form the square pipe part 1 and the tapered pipe part 2 respectively, and then Then the tapered pipe part 2 is respectively welded to both ends of the square pipe part 1 by means of seamless welding. However, since the traditional forming method is to connect the tapered pipe part 2 to the two ends of the square pipe part 1 by means of seamless welding, the formed special-shaped stainless steel pipe has the problem of insufficient strength, which cannot be applied to the strength of the special-shaped sta...
