Select materials: select 430 stainless iron sheet 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；
Cover half: selecting 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 be fixed on clapper die spotting press by mould, and clean mould；
Annealing: being placed in annealing furnace by the plectane after cutting and make annealing treatment, annealing furnace keeps temperature more than 1095 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 placed in the mould position that die depth is minimum, opens clapper die spotting press, be warming up to 550 DEG C ~ 650 DEG C,
Carry out for the first time Hot drawing, after Hot drawing, carry out above-mentioned solutionizing step for the first time again, then blank is placed in mould carries out the
Second heat drawing, carries out blank after second heat drawing third time Hot drawing school shape, protects when third time Hot drawing school shape
Pressure processes；
Close up: by the gas cylinder semi-finished product after drawing at a temperature of 760 ~ 815 DEG C, squeeze out bottleneck by mould；
Clean: acid solution is injected into metal bottle inner chamber, 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 employing 430 stainless irons, can effective anticorrosive oxidation, 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
Below by specific embodiment, the present invention will be further described.
