Abstract
The invention discloses a deep-drawing technique for stainless steel shuttle-like pieces. The deep-drawing technique for stainless steel shuttle-like pieces comprises the steps of material selection, solution treatment, grinding, deep-drawing, cutting, cleaning, primer spraying, surface paint spray-coating and the like, specifically, a ground blank is subjected to primary cold deep-drawing, then solution treatment and secondary cold deep-drawing are carried out after primary cold deep-drawing, the blank is subjected to third-time heat deep-drawing and shaping after secondary cold deep-drawing, and pressure maintaining treatment is carried out during the third-time heat deep-drawing and shaping. By means of the deep-drawing technique for stainless steel shuttle-like pieces, the production efficiency and the attractive degree of shuttle-like pieces are effectively improved.
Description
Technical field
Drawing and forming field in hot forming of the present invention, specifically a kind of rustless steel fusiform component deep-drawing technique.
Background technology
At present, in heat forming technology, for special-shaped thin-slab structure part, typically take drawing and forming or stamping without blank holder.And drawing and forming part woollen mostly is the regular shape such as rectangle or circle, the accurate drawing of curved-surface structure part is difficult to carry out, flanging position is commonly designed bigger than woollen, generally rectangle is round waits regular shape, push down blank, and because blank holder puts down the enforcement of wrinkle function, make pressure-pad-force tend to uniformly in marginal distribution；The especially special-shaped thin-slab structure part technique of design is difficult to effectively calculate pressure-pad-force and stamping press, and forming defects occurs in the improper part that easily causes of proportioning, and the regulation and control for pressure-pad-force need substantial amounts of test to grope.And it is not provided with blank holder, use punching press hot forming, generally require and take progressive molding and repeatedly suppress method solution wrinkle, the problems of crack of leveling, be unfavorable for the quality of product and the raising of production efficiency.
Summary of the invention
It is desirable to provide a kind of rustless steel fusiform component deep-drawing technique, to solve the problems referred to above.
For achieving the above object, technical scheme is as follows:
A kind of rustless steel fusiform component deep-drawing technique, it is characterised in that comprise the following steps:
Select materials: select 304 stainless steel materials as blank, carry out Size calculation according to fusiform component size, then according to the target size after calculating, blank is cut into tabular with cutting machine；
Solution treatment: the plectane after cutting is carried out solution treatment, keeps temperature 1050 DEG C, 15 minutes persistent period, cool down the most rapidly；
Polishing: carry out surface polishing, sanding burr is clean；
Drawing: the blank after polishing is carried out first time the most cold drawn deeply, the most cold drawn deep after carry out above-mentioned solutionizing step 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；
Cutting: after the semi-finished product after drawing and forming are cooled to room temperature, carry out cutting process, process part.
Clean: the part processed is inserted in acid solution, keeps 15 minutes, finally discharge acid solution.
Basecoat paint: to surface spraying/roller coating prime paint, prime paint is white fused alumina sand grains, makes roughness reach 8 ~ 15 μm, and is dried 30 minutes；
Surface lacquer sprays: at prime paint surface spraying/roller coating floating coat paint, described floating coat paint is aliphatic polyurethane glass flake paint, paints three times polyurethane coating varnishes of spraying at floating coat continuously after being dried 0.5-1.5 hour.
Further, described drawing step, in forming process, needs after each drawing to be observed the drawing state of part, 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.
Further, the coating layer thickness of described prime paint is 100 μm-120 μm.
The beneficial effects of the present invention is: processed by repeatedly load-unload and be effectively increased rolling accuracy, make the wall thickness accuracy error super many 2% of drawing aftershaping, and have employed acid solution and be carried out, go out the iron filings on top layer, be allowed to more attractive.And tool structure of the present invention is simple, easy for operation, reduces batch product cost, improve production efficiency.
