Abstract
The invention discloses a drawing technology for a steel cylinder. The drawing technology comprises the steps of material selecting, solution treatment, polishing, drawing, closing-up, cleaning and the like. First time of cold drawing is conducted on a polished blank, the step of solution treatment is conducted after the first time of cold drawing, then second time of cold drawing is conducted, third time of heat drawing shape correcting is conducted on the blank on which the second time of cold drawing is conducted, and pressure maintaining treatment is conducted during the third time of heat drawing shape correcting. The integral quality of the steel cylinder is ensured by means of multiple times of drawing and solution treatment.
Description
Technical field
The present invention relates to gas cylinder processing technique field, specifically a kind of steel cylinder deep-drawing technique.
Background technology
As clean energy resource, natural gas is widely used in every field, no matter be that life production all plays key player.Accordingly, the development of the pressure vessel of filling natural gas compressing gas just seems particularly necessary, due to the inflammable and explosive characteristic of natural gas, very high to its bubble-tight requirement of container.The technique of bad manufacture can cause the Wall-Thickness Difference of container bottle excessive, and the difference in quality of seamless cylinder is very large, equally, if temperature controls to cause bottom gas cylinder for bad time and leaks gas when hot spinning receives the end in large batch of production process, leaves major safety risks.
Summary of the invention
The present invention aims to provide a kind of steel cylinder deep-drawing technique, to solve the problem.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of steel cylinder deep-drawing technique, is characterized in that, comprise the following steps:
Select materials: select 304 stainless steel materials as blank, carry out Size calculation according to steel cylinder size, then according to the target size after calculating, blank is cut into plectane with cutting machine;
Solution treatment: the plectane after cutting is carried out solution treatment, keeps temperature 1050 DEG C, 15 minutes duration, then cools rapidly;
Polishing: carry out surface finish, sanding burr is clean;
Drawing: the blank after polishing is carried out first time deeply cold drawn, first time cold drawn dark after carry out above-mentioned solutionizing step again, carry out second time more deeply cold drawn, cold drawn for secondary dark rear blank is carried out third time Hot drawing school shape, carries out pressurize process when third time Hot drawing school shape;
Close up: by the gas cylinder semi-finished product after drawing at 800 ~ 1000 DEG C of temperature, squeeze out bottleneck by mould;
Cleaning: acid solution is injected into metal bottle inner chamber, fills rear maintenance 15 minutes, finally discharge acid solution.
Further, described drawing step, in forming process, needs after each drawing to observe the drawing state of part, need carry out smoothing wrinkle process, then carry out drawing next time if there is fold.
Further, described drawing step, first time drawing up to final drawing and forming residue 20mm ~ 30mm height, second time drawing is up to final drawing and forming 5 ~ 8mm height.
Further, described drawing step keeps deep drawing speed to be 80 ~ 110mm/min.
Beneficial effect of the present invention is: effectively improve rolling accuracy by repeatedly load-unload process, make the steel cylinder wall thickness accuracy error not super many 2% of drawing aftershaping, and adopt 304 stainless steels, can effective anticorrosive oxidation, avoid the problem of steel cylinder shortening in service life in specific environment, have employed acid solution to clean, go out the iron filings on top layer, make it more attractive in appearance.
Detailed description of the invention
Below by specific embodiment, the present invention will be further described.
A kind of steel cylinder deep-drawing technique, is characterized in that, comprise the following steps:
Select materials: select 304 stainless steel materials as blank, carry out Size calculation according to steel cylinder size, then according to the target size after calculating, blank is cut into plectane with cutting machine;
Solution treatment: the plectane after cutting is placed in Solution Treatment Furnace and carries out solution treatment, Solution Treatment Furnace keeps temperature 1050 DEG C, 15 minutes duration, then cools rapidly;
Polishing: carry out surface finish, sanding burr is clean;
Drawing: the blank after polishing is carried out first time deeply cold drawn, first time cold drawn dark after carry out above-mentioned solutionizing step again, carry out second time more deeply cold drawn, cold drawn for secondary dark rear blank is carried out third time Hot drawing school shape, carries out pressurize process when third time Hot drawing school shape; Described drawing step, in forming process, needs after each drawing to observe the drawing state of part, need carry out smoothing wrinkle process, then carry out drawing next time if there is fold.Described drawing step, first time drawing up to final drawing and forming residue 20mm ~ 30mm height, second time drawing is up to final drawing and forming 5 ~ 8mm height.Described drawing step keeps deep drawing speed to be 80 ~ 110mm/min.
Close up: by the gas cylinder semi-finished product after drawing at 800 ~ 1000 DEG C of temperature, squeeze out bottleneck by mould;
Cleaning: acid solution is injected into metal bottle inner chamber, fills rear maintenance 15 minutes, finally discharge acid solution.
The present invention effectively improves rolling accuracy by repeatedly load-unload process, make the steel cylinder wall thickness accuracy error not super many 2% of drawing aftershaping, and adopt 304 stainless steels, can effective anticorrosive oxidation, avoid the problem of steel cylinder shortening in service life in specific environment, have employed acid solution to clean, go out the iron filings on top layer, make it more attractive in appearance.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
