Abstract
The invention discloses a titanium steel cylinder deep drawing technology. The titanium steel cylinder deep drawing technology comprises the steps of material selection, annealing, polishing, deep drawing, opening contracting, cleaning and the like. Primary cold deep drawing is conducted on a polished blank. The annealing step is conducted after the primary cold deep drawing. Then, secondary cold deep drawing is conducted. Third hot drawing sizing is conducted on the blank obtained after secondary cold deep drawing. When the third hot drawing sizing is conducted, pressure maintaining is conducted. By the adoption of repeated deep drawing and annealing, the overall quality of steel cylinders is guaranteed.
Description
Technical field
The present invention relates to gas cylinder processing technique field, specifically a kind of titanium material 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 titanium material 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 titanium material steel cylinder deep-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;
Annealing: the plectane after cutting is placed in annealing furnace and carries out annealing in process, annealing furnace keeps temperature more than 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 carried out first time deeply cold drawn, first time cold drawn dark after carry out above-mentioned annealing steps 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 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.
Detailed description of the invention
Below by specific embodiment, the present invention will be further described.
A kind of titanium material steel cylinder deep-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;
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 carried out first time deeply cold drawn, first time cold drawn dark after carry out above-mentioned annealing steps 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 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.
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 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.
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.
