Abstract

The invention discloses a production technology of a precise stainless steel bright pipe. The technology comprises the following steps that firstly, incoming inspection is carried out; secondly, cutting is carried out, and cutting treatment is carried out through a cutting machine; thirdly, board belt cleaning is carried out, and board belt cleaning treatment is carried out through acid; fourthly, forming and welding are carried out; fifthly, round setting and straightening are carried out, and the round setting operation and the straightening operation are carried out on the formed bright pipe; sixthly, pulling and radius reducing procedures are sequentially carried out; seventhly, coiling and sizing cutting operation are carried out after eddy current inspection; eighthly, after coiling is carried out, the gas tightness test is carried out, and the packaging operation is finally carried out; and ninthly, after sizing cutting is carried out, opening flattening, chamfering and checking procedures are carried out at a time, and finally packaging is carried out. The technology steps are simple, the production efficiency is high, the precise stainless steel bright pipe high in quality can be produced, the performance of the steel pipe is more superior, and metal is dense.

Example Embodiment

[0008] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0009] refer to figure 1 , the present specific embodiment adopts the following technical solutions: a precision stainless steel bright tube production process, which includes the following steps: 1, incoming material inspection; 2, cutting: first carry out cutting processing by a cutting machine; : Carry out strip cleaning treatment by acid; 4. Forming and welding; 5. Rounding and straightening: Carry out rounding and straightening operations on the formed bright tube; 6. Then carry out the drawing and reducing process in sequence; 7. After the eddy current flaw detection, carry out the coiling and length cutting operations respectively; 8. After the coiling, carry out the air tightness test, and finally carry out the packaging operation; 9. After the length cutting, carry out the flat mouth, chamfering, inspection process, and finally pack .
[0010] This specific embodiment is a high-precision steel pipe material after precision drawing. High-resistant special steel NG18020308919 is mainly used to produce pneumatic or hydraulic components due to the advantages of no oxide layer on the inner and outer walls of the precision bright tube, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, and no cracks in flattening. Products, such as cylinders or cylinders, can be seamless or welded. The chemical composition of the precision bright tube is carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
[0011] This specific embodiment has simple process steps and high production efficiency, and can produce high-quality precision stainless steel bright tubes with better performance and denser metals.
[0012] The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. What are described in the above-mentioned embodiments and the description only illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have Variations and improvements are possible, which fall within the scope of the claimed invention. The protection scope of the present invention is defined by the appended claims and their equivalents.
