Abstract
The invention discloses a titanium steel cylinder hot drawing process which includes the steps of material selecting, mold fixing, mold testing, annealing, grinding, drawing, shell nosing, cleaning and the like. Primary hot drawing is conducted on a ground blank material, solution treatment is conducted after primary hot drawing, secondary hot drawing is conducted, tertiary hot drawing and correcting are conducted on a blank where secondary hot drawing is conducted, and pressure maintaining is conducted during the tertiary hot drawing and correcting. By means of multiple times of drawing and solution treatment, the overall quality of a steel cylinder is ensured.
Description
Technical field
The present invention relates to gas cylinder processing technique field, specifically a kind of titanium material steel cylinder Hot 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 titanium material steel cylinder Hot drawing technique, to solve the problem.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of titanium material steel cylinder Hot drawing technique, is characterized in that, comprise the following steps:
Select materials: select titanium material sheet material 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;
Cover half: select Hot drawing mould according to the plectane after cutting, mould at least has the mould position that three degree of depth are deepened successively, and is fixed on clapper die spotting press by mould, and cleaning die;
Die trial: with price inexpensively, the comparatively good aluminium of processing characteristics, as experiment material, carries out experiment processing with mould, and whether inspection mould can machine-shaping;
Annealing: the plectane after cutting is placed in annealing furnace and carries out annealing in process, annealing furnace keeps temperature 550 ~ 600 DEG C, 15 ~ 30 minutes duration, then cools rapidly;
Polishing: carry out surface finish, sanding burr is clean;
Drawing: the blank after polishing is placed in the minimum mould position of die depth, open clapper die spotting press, be warming up to 550 DEG C ~ 650 DEG C, carry out first time Hot drawing, above-mentioned solutionizing step is carried out again for the first time after Hot drawing, again blank is placed in mould and carries out second time Hot drawing, blank after second heat drawing is carried out third time Hot drawing school shape, carry out pressurize process when third time Hot drawing school shape;
Close up: by the gas cylinder semi-finished product after drawing at 680 ~ 720 DEG C of temperature, squeeze out bottleneck by mould;
Cleaning: acetone soln is injected into metal bottle inner chamber, fills rear maintenance 15 minutes, finally discharge acetone soln.
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 titanium material, can effective anticorrosive oxidation, avoid the problem of steel cylinder shortening in service life in specific environment, have employed acetone soln to clean, go out the iron filings on top layer, make it more attractive in appearance.
