The invention discloses a kind of production technologies of stainless steel tube, comprising the following steps: (1) steel are cut into the sheet material of different in width, checked sheet material, and by sheet material volume on wrap-up;(2) sheet material is sent to molding machine, sheet material is rolled into the steel pipe of required size by molding machine;(3) steel pipe is welded into for coil of strip is formed by welding gun in shaping steel tube, steel pipe is carried out preventing oxidation processes in the welding process, is cooled down after the completion of welding by cooling water;(4) welding bead is polished flat, shaping is carried out to outer diameter of steel pipes, circularity, verticality, the technical parameter of steel pipe is made to reach production standard requirements;(5) stainless steel tube is cut into the steel pipe of required length by cutter device, welding effect of the present invention is good, good forming effect, largely improves the quality of product, reduces the fraction defective of product, improve production efficiency, has relatively high practicability.

Description

A kind of production technology of stainless steel tube
Technical field
The present invention relates to steel pipe's production technical field, especially a kind of production technology of stainless steel tube.
Background technique
In domestic market, stainless steel tube is generally divided into two kinds, low and middle-grade times general dedicated with pipe and top grade Pipe.Low and middle-grade secondary its preparation process of precision welding stainless steel tube tradition, main improvement direction are to try to meet domestic quality mark It is quasi-.High-grade precision welding stainless steel tube has higher requirement to the performance of tubing, according to the difference of service condition, specifically Performance is required to meet the requirement of international standard.Therefore it must constantly bring forth new ideas in preparation process, be constantly progressive, just adapt to The international standard of continuous improvement.However the preparation process of stainless steel tube is an entirety of multiple set of steps, only to a certain A process improves, and effect is limited, and the semi-finished product after each step its treated that result is that have phase Corresponding standard, how each link can do better be stainless steel tube preparation process amelioration main target. It is inadequate to the attention degree of polishing in traditional handicraft, do not recognize that pipe to the important parts of end product quality;In cold rolling Aspect, traditional handicraft is big since there are bending deformations after heat treatment, and qualification rate is low, the big problem of hardness fluctuations range, to obtain High rigidity requires heat treatment bending deformation small again, it is necessary to using the cooling means compared with mitigation, such as heating bath grade quench air-cooled is quenched Fire etc., but the requirement of HRC60~62 is not achieved in hardness again.In traditional handicraft, (pickling is given up the hydrofluoric acid of cylinder using pickling Add nitric acid solution, main to achieve the purpose that degreasing by corroding removing, this not only can make steel tube surface degreasing not to the utmost, but also can make At the corrosion phenomenon of steel tube surface, the corrosion resistance of steel pipe is thus reduced, this is a kind of extremely unreasonable mode, and is existed The disadvantages of overpickling, deficient pickling, each pond of acid cleaning process requires special messenger and keeps an eye on its process time.) inside pipe wall cleaning tradition Technique is only simply rinsed by giant, and cleaning effect is very poor, also very waste water resource, while inefficiency.
Summary of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of production technology of stainless steel tube.
The technical solution adopted in the present invention is mainly: a kind of production technology of stainless steel tube, comprising the following steps: (1) Steel are cut into the sheet material of different in width, sheet material is checked, and by sheet material volume on wrap-up;(2) sheet material is sent To molding machine, sheet material is rolled into the steel pipe of required size by molding machine;(3) coil of strip will be formed by welding gun in shaping steel tube It is welded into steel pipe, steel pipe is carried out preventing oxidation processes in the welding process, be cooled down after the completion of welding by cooling water; (4) welding bead is polished flat, shaping is carried out to outer diameter of steel pipes, circularity, verticality, the technical parameter of steel pipe is made to reach production standard It is required that;(5) stainless steel tube is cut into the steel pipe of required length by cutter device.
As an improvement of the above technical solution, in the step (3), being passed through argon gas or nitrogen prevents steel pipe in welding process Oxidation.
As a further improvement of the above technical scheme, in the step (4), the welding bead of steel pipe is beaten by flap wheel It polishes whole.
Further, the flap wheel and steel pipe are directly in 25-45 ° of angle.
Further, in the step (4), the wall thickness of steel pipe is 0.5-1.5mm.
The beneficial effects of the present invention are:
A kind of production technology of stainless steel tube of the invention carries out in different ways according to the difference of outer diameter of steel pipes size Cutting, and combined according to the steel pipe of different-thickness using different welding guns and welding, and by control welding gun electric current, so that Welding temperature is balanced, and welding effect is good, good forming effect, largely improves the quality of product, reduces product not Yield improves production efficiency, has relatively high practicability.
Specific embodiment
The present invention will be further described in detail with reference to the specific embodiments.
The production technology of a kind of stainless steel tube of the invention, comprising the following steps: (1) steel are cut into different in width Sheet material checks sheet material, and sheet material is rolled up on wrap-up;(2) sheet material is sent to molding machine, molding machine is by sheet material Roll into the steel pipe of required size;(3) steel pipe is welded into for coil of strip is formed by welding gun in shaping steel tube, in the welding process Steel pipe is carried out to prevent oxidation processes, is cooled down after the completion of welding by cooling water;(4) welding bead is polished flat, to steel pipe Outer diameter, circularity, verticality carry out shaping, and the technical parameter of steel pipe is made to reach production standard requirements;It (5) will not by cutter device Rust steel pipe is cut into the steel pipe of required length.
Preferably, in the step (3), being passed through argon gas or nitrogen prevents steel pipe in welding process from aoxidizing, so as to reality Steel pipe in existing welding process prevents oxidation processes, and argon gas and nitrogen are easy to obtain, at low cost.
Preferably, in the step (4), the welding bead of steel pipe is polished flat by flap wheel, may be implemented to steel Quickly finishing polishes pipe.
Preferably, the flap wheel and steel pipe are directly in 25-45 ° of angle, so as to realize better polishing.
Preferably, in the step (4), the wall thickness of steel pipe is 0.5-1.5mm, it is of course also possible to be the steel of other thickness Pipe, the present invention are not limited to this.
A kind of production technology of stainless steel tube of the invention, in different ways according to the difference of outer diameter of steel pipes size It is cut, and is combined according to the steel pipe of different-thickness using different welding guns and welding, and pass through control welding gun electric current, So that welding temperature is balanced, welding effect is good, good forming effect, largely improves the quality of product, reduces product Fraction defective, improve production efficiency, have relatively high practicability.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, as long as with essentially identical Means realize that the technical solution of the object of the invention belongs within protection scope of the present invention.
