Description

Известен способ поверхностной закалкп стальных деталей токами высокой частоты, перемещаемых относительно нагревательного индуктора с последовательным нагревам участков закаливаемой поверхности с применением жидких охладителей.The known method of surface hardening of steel parts by high-frequency currents moving relative to the heating inductor with sequential heating of the areas of the hardened surface using liquid coolers.

Описываемый способ поверхностной закалки стальных деталей токами высокой частоты отличаетс  от известных тем, что закалка производитс  без охлаждающей жидкости за счет отдачи тепла от нагретых участков .детали - не нагретым участкам.The described method of surface hardening of steel parts by high-frequency currents differs from the known ones in that quenching is performed without a coolant due to the release of heat from the heated sections. The parts to the non-heated sections.

Перемеща  закаливаемую деталь со скоростью, обеспечивающей необходимый нагрев детали под индуктором и теплоотдачу остальной массе закаливаемой детали по выходе из-под индуктора.Moving the hardened part at a speed that provides the necessary heating of the part under the inductor and heat transfer to the rest of the mass of the hardened part as it leaves the inductor.

С целью регулировани  теплоотдачи нагреваемой детали примен етс  или искусственное охлаждение стола, на котором устанавливаетс  закаливаема  деталь, или теплова  изол ци  среды, или подогрев детали.In order to regulate the heat transfer of the heated part, either artificial cooling of the table on which the part is being hardened, or thermal insulation of the medium, or heating the part is used.

Поверхностна  закалка зубьев шестерен производитс  при помощи петлевого индуктора, а нагрев зубьев производ т поочередно через каждые два-три зуба.The surface hardening of the gear teeth is done using a loop inductor, and the teeth are heated alternately every two to three teeth.

Скорость перемещени  закаливаемой детали определ ют по цветам побежалости, а глубину сло  поверхностной закалки - по ширине дорожек цветов побежалости.The speed of movement of the hardened part is determined by the colors of the tint, and the depth of the layer of surface hardening is determined by the width of the paths of the colors of the tint.

Предложение практически проверено в производственной практике и может быть широко применено в различных отрасл х промьппленности .The offer has been practically tested in production practice and can be widely applied in various industries.
