Abstract
The invention discloses an anti-corrosion steel cylinder drawing process which includes the steps of material selection, solution treatment, grinding, drawing, sealing, washing and the like. First-time cold drawing is performed on a ground blank, solution treatment is performed after first-time cold drawing is performed, second-time cold drawing is then performed, third-time thermal drawing and shaping is performed on the blank subjected to second-time cold drawing, and pressure is maintained in the third-time thermal drawing and shaping process. Multiple times of drawing and solution treatment are adopted for guaranteeing the overall quality of a steel cylinder.
Description
Technical field
The present invention relates to gas cylinder processing technique field, specifically a kind of anticorrosion 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 anticorrosion 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 anticorrosion steel cylinder deep-drawing technique, is characterized in that, comprise the following steps:
Select materials: select 316 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 1850-2050 °F, 30 minutes duration or more, 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 1900-2350 °F 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 316 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 anticorrosion steel cylinder deep-drawing technique, is characterized in that, comprise the following steps:
Select materials: select 316 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, solution treatment keeps temperature 1850-2050 °F, 30 minutes duration or more, 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 1900-2350 °F 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 316 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.
