Description
При глубокой выт жке стальных деталей на их поверхности получаютс задиры и риски вследствие налипани на рабочий инструмент металла.:With deep drawing of steel parts, scratches and risks are formed on their surface due to sticking to the metal working tool .:
Разделение поверхностей выт гиваемого металла и И1тампа введеliHCM в жидкие смазки таких твер .дых иаполиителей, как графит, тальк, бентонит и др.,. не вл етс достаточно эффективным средетвом, устран ющим налипание.Separation of the surfaces of the metal being drawn and the I1tamp introduced HPMM into liquid lubricants of such solids and solvents such as graphite, talc, bentonite, etc.,. not a sufficiently effective anti-sticking agent.
Описываемый способ предохран ет стальные издели при выт жке ОТ задиров.The described method protects steel products when drawing from scoring.
Заготовку, под.л.ежаш,ую выт жке , подвергают травлению в сол ной или серной кислотах. После Травлени заготовку не подвергают нейтрализации, а промывают в холодной и,;и1 гор чей воде. После ЭТОГО заготовку оставл ют на воздухе на 20-30 минут, вследствие чего на ее поверхности образуетс равномерный же.птый налет гидрата окиси железа (FeOH);;. Заготовку с таким валетом окунают в 20%ный мыльный раствор и затем сушат . Образовавша с пленка из подсло гидрата окиси железа, покрытого 20%-ной мыльной смазкой вл ете падежным раздел ющим слоем ОТ B3aHjMHoro контакта поверхности инструмента и заготовки, ЧТО предотвраптает палипа1Н1е и, следовательно, образование царапин и задиров на иJтaмнyeмыx детал х .The billet, under the lash, is stretched, etched in hydrochloric or sulfuric acid. After Etching, the billet is not subjected to neutralization, but is washed in cold and,; and 1 hot water. After this, the billet is left in the air for 20-30 minutes, as a result of which a uniform iron oxide hydrate (FeOH) forms on its surface ;;. A billet with such a jack is dipped into a 20% soap solution and then dried. An iron oxide hydrate sublayer formed from a film coated with a 20% soap lubricant is the case separating layer from the contact between the tool and the workpiece surface, which prevents palip1H1e and, therefore, the formation of scratches and tears on iJm.
Предмет изобретени Subject invention
. Способ предохрапени стальных деталей от задиров прн выт жке с травле1П ем их в сол ной или серной кислотах, промывкой в воде и обработкой их 20%-ной мыл1Я1ой емазкой, о т л и ч а ю щ и и с тем, ЧТО дл получени прочного разделительного сло между заготовкой и инструментом в качестве подсло под 20%-ную мыльную смазку иримеиена пленка гидрата окиси железа .. The method of protecting steel parts from scratching when stretched by etching them in hydrochloric or sulfuric acids, washing them in water and treating them with 20% soap and water, so as to obtain a durable separation layer between the workpiece and the tool as a sublayer under the 20% soap lubricant irimeyena iron oxide hydrate film.
2. Способ выполнени по п. 1, о Т л и ч а ю щ и и с тем, что дл образоваии равномерной гидратМ 106399 ной пленки, травлени в заготовки, после их воде, оставл ют на воздухе в течекислоте и промывки в ще 20-30 минут.2. The method of execution according to claim 1, about T l and h and y and the fact that in order to form a uniform hydrate M 106399 film, etched into the workpiece, after their water, left in the air in the acid and washing in the slit 20 -30 minutes.
