Abstract
The invention discloses a kind of high rigidity Pneumatic automobile high-pressure cylinder production technology, including selecting materials, anneal, polish, drawing, close up, clean, the step such as japanning, it is the most cold drawn deeply by the blank after polishing is carried out first time, the most cold drawn deep after carry out above-mentioned annealing steps again, carry out second time more cold drawn deeply, cold drawn for secondary deep rear blank is carried out third time Hot drawing school shape, carries out pressurize process when third time Hot drawing school shape.Repeatedly load-unload and annealing is used to ensure the total quality of steel cylinder.
Description
Technical field
The present invention relates to gas cylinder processing technique field, specifically a kind of high rigidity Pneumatic automobile high-pressure cylinder production technology.
Background technology
As clean energy resource, natural gas is widely used in every field, and whether life produces and all plays important angle
Color.Accordingly, the development of pressure vessel of filling natural gas compressing gas just seems particularly necessary, due to natural gas inflammable easily
Quick-fried characteristic, its bubble-tight requirement to container is the highest.The technique of bad manufacture can cause the Wall-Thickness Difference mistake of container bottle
Greatly, the difference in quality of seamless cylinder is very big, equally, if temperature controls when in large batch of production process, hot spinning receives the end
Cause for bad time and leak gas bottom gas cylinder, leave major safety risks.
Summary of the invention
It is desirable to provide a kind of high rigidity Pneumatic automobile high-pressure cylinder production technology, to solve the problems referred to above.
For achieving the above object, technical scheme is as follows:
A kind of high rigidity Pneumatic automobile high-pressure cylinder production technology, it is characterised in that comprise the following steps:
Select materials: select 410 stainless steel materials as blank, carry out Size calculation according to steel cylinder size, then use cutting machine according to
Blank is cut into plectane by the target size after calculating；
Annealing: being placed in annealing furnace by the plectane after cutting and make annealing treatment, annealing furnace keeps temperature 800 ~ 940 DEG C, continues
15 minutes time, cool down the most rapidly；
Polishing: carry out surface polishing, sanding burr is clean；
Drawing: the blank after polishing is carried out for the first time the most cold drawn deeply, the most cold drawn deep after carry out above-mentioned annealing steps again, then enter
Row second time is cold drawn deeply, cold drawn for secondary deep rear blank is carried out third time Hot drawing school shape, enters when third time Hot drawing school shape
Row pressurize processes；
Close up: by the steel cylinder semi-finished product after drawing at a temperature of 800 ~ 1000 DEG C, squeeze out bottleneck by mould；
Clean: acid solution is injected into steel cylinder intracavity, keep 15 minutes after filling, finally discharge acid solution；
Priming: cleaned steel cylinder is dried process 20 30min, to the dried spraying carrying out priming paint, spraying
Time spray gun and sprayed surface distance be 10 30cm, keep spray gun at right angles to run with coated article face；
Air brushing: the above-mentioned blank through basecoat paint is thermally dried process, then dried steel cylinder is polished
Process, and stick pattern flower pattern at the steel cylinder polished, the blank pasting flower pattern is carried out color spray；
Topcoating: the above-mentioned blank through color spray is thermally dried process 20 40min, and temperature controls 60 80 Celsius
Degree, carries out finishing varnish process to steel cylinder surface, then it is dried process.
Further, described drawing step, in forming process, needs after each drawing to carry out the drawing state of part
Observation, need to carry out smoothing wrinkle process if there is fold, then carry out drawing next time.
Further, described drawing step, in first time drawing up to final drawing and forming residue 20mm ~ 30mm height,
Drawing is up to final drawing and forming 5 ~ 8mm height for the second time.
Further, described drawing step keeps deep drawing speed to be 80 ~ 110mm/min.
The beneficial effects of the present invention is: processed by repeatedly load-unload and be effectively increased precision, make the steel of drawing aftershaping
Bottle wall thickness accuracy error super many 2%, and use 410 rustless steels, hardness strength can be improved, it is to avoid steel cylinder is in specific environment
The problem that service life shortens, have employed acid solution and is carried out, and goes out the iron filings on top layer, is allowed to more attractive.
Detailed description of the invention
