Abstract
A technology for making an enamelled container features that every parts of the enamelled container are individually blanked, enamelled and sintered to obtain enzmelled parts, and all enamelled parts of a container are connected together by lock beading to form a whole. Its advantages are no need of welding and grinding welded seams, and smooth surface.
Description
The present invention relates to enamelled vessel processing.
Well-known enamel is to make after a kind of rake unorganic glass raw material is founded that the enamel glaze slip is coated on the metallic matrix again and form the matrix material of mortise with metal.It not only has advantages such as the intensity height of metal, easy processing, also has good characteristics such as smooth in appearance is attractive in appearance, non-corrosive, easy cleaning, nontoxic, cold-resistant heat shocks, acid-and base-resisting, insulation.Enamelled vessel all has wide model purposes in industrial production and daily life, existing enamelled vessel make generally be with metal blank through punching press or the application of slip after being welded into the shape of requirement, fire and form, this just unavoidably produces following defective because of smooth smooth degree difference of blank weld seam has influence on when the enamel glaze slip combines with metal blank: 1, surperficial rough and uneven in surface; 2, the stress of welding back generation is difficult eliminates; 3, burning till the back porcelain facing bubble, quick-fried point, mesh-like, porcelain facing dew iron occur, takes off porcelain.The method of blank weld seam of taking conscientiously to polish is not to improve and to avoid these defectives, will be the thing of trouble very but especially the inwall of closed container is handled in industrial production.The present invention proposes to be processed into the enamel parts earlier, then the enamel parts is connected into the design of container, with the detrimentally affect that reduces and avoid the weld seam of blank welding to cause.
Technical characterictic of the present invention is to constitute the metal blank sub-unit application of slip (going up enamel) of container and burns till, and then the enamel parts is connected into integral body through rolling up to buckle.The patent documentation report that connects with the enamel face component has flanging, folder weldering and with the connecting parts connection etc., does not relate to the volume button and connect by retrieval.Volume button of the present invention is to make crimping before the application of slip of the edge of need coupling components, and crimping fastened mutually, tightens up when the back connection was burnt till in the application of slip.
Description of drawings: figure one technical process
Figure two volume button synoptic diagram
Among the figure: 1, the edge shape of parts (8); 2, the edge shape of parts (9); 3, the mated condition of parts (8) and (9); 4, parts (8) and (9) connect 90 ° of interfacial angle states of formation; 5, parts (8) and (9) are connected into 180 ° of flat states; 6,7, only be coated with the part of ground-coat enamel at metal blank crimping internal surface; 8,9, container parts.
The present invention is achieved in that for ease of surface treatment the enamelled vessel branch Solution becomes several parts, becomes according to the metal blank of drawing requirement blanking with parts earlier Shape connects the edge and makes on request crimping, and blank is through pickling; Second step is gold Belonging to blank is coated with ground-coat enamel, dries and burn till; The 3rd step was coated with cover-coat enamel, oven dry is burnt till; The The special equipment of four steps with the volume button will connect partly cooperation, volume button, tighten up. Will The parts of enamel face buckles with mechanical application of force volume that to tighten up integral body of formation be the present invention Feature, require porcelain not occur taking off at the position that connects after the volume button, reveal iron, The phenomenons such as porcelain facing bursts apart will be eliminated the porcelain facing that weld seam brings when welding because of blank and lack Fall into, with the porcelain facing parts stand machining must have the performance of enamel special Requirement, the obvious incompatibility above-mentioned requirements of the enamel prescription of domestic enamel vessel needs Strengthen the impact resistance of ground-coat enamel, improve its toughness, improve it and infiltrate metal The performance that blank is combined closely; The cold-hot cataclysm performance that cover-coat enamel is then had relatively high expectations To prolong the service life of container, provide ground-coat enamel and cover-coat enamel through the repetition test screening Prescription as follows:

30.5-1 R-represents K in the prescription, Na, element, V-26 is the enamel additive, above-mentioned batching is used with suitable quantity of water (be about material heavy 35%) furnishing pulpous state, burn till the regulation that end porcelain impact resistance (being adhesion property) is better than national standard by above-mentioned ground-coat enamel prescription, the cold-resistant heat shocks performance of cover-coat enamel can reach 10 face porcelain of the cold and hot cataclysm of the molten point of lead foil and not split.
Embodiment: bucket promptly uses the present invention to roll up and is fastened as type technology in the utility application 96205493.3 enamel volume button-type sun power accumulator, bucket connects for the right cylinder ladle body is fastened as with the bung volume of two ends dribbling face in warding off entirely, carry out earlier the blank of ladle body and bung respectively, bung blank (8) crimping is (1), ladle body blank (9) crimping is (2), blank is through pickling then, being coated with the ground-coat enamel oven dry burns till, be coated with cover-coat enamel (crimping inner face (6) (7) part be not coated with cover-coat enamel) oven dry again and burn till, then the enamel bung that burns till and enamel ladle body crimping are cooperated to be (3) and to roll up with the mechanical application of force and be fastened as the closed container that (4) promptly make complete enamel surface.The interior bucket specification of processing at present has Φ 450mm, L1000, and 1250 and 1550mm, ladle body has stiffening web, and container bears 1-1.5 kilogram pressure.
It is the novel process that the enamel parts connect that the volume of band enamel face is buckled connection, is characterized in that the enamel that can stop to be caused by the blank weld seam reveals defectives such as iron, the making of the closed container of the application of slip in being specially adapted to require.
