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.

Description

technical field [0001] The invention relates to the technical field of bright tube production, in particular to a precision stainless steel bright tube production process. Background technique [0002] Precision steel pipe is a high-precision steel pipe material processed by cold drawing or hot rolling. Since the inner and outer walls of precision steel pipes have no oxide layer, withstand high pressure without leakage, high precision, high smoothness, cold bending without deformation, flaring, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as cylinders or Cylinders can be seamless or welded. The chemical composition of precision steel pipes includes carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr. The traditional precision stainless steel bright tube production process is more complicated and the production efficiency is low, so it is necessary to design a new precision stainless steel b...
