Изобретение относитс к способам индукционной закалки инструмента.This invention relates to methods for induction hardening of tools.
Известен способ индукционной закалки инструмента , включающий нагрев токами высокой частоты при частоте тока до 450 кгц и охлаждение в закалочной среде.The known method of induction hardening tool, including heating currents of high frequency at a current frequency of 450 kHz and cooling in a quenching medium.
Онисываемый способ позвол ет повысить равномерность закалки по длине инструмента . Дл этого нагрев производ т при частоте тока более 3 мгц.This method allows to increase the uniformity of quenching along the tool length. For this, heating is performed at a current frequency of more than 3 MHz.
Описываемый снособ индукционной закалки инструмента, например надфилей с заостренным концом, включает сквозной индукционный нагрев до 850-900°С токами частотой более 3 Мгц со скоростью в интервале фазовых превращений 100-200°С/сек и закалку в масло или расплав селитры нри 170-220°С, что обеспечивает структуру, состо щую из мелкодисперсного мартенсита и карбидов.Described induction hardening tool, for example a file with a pointed end, includes end-to-end induction heating up to 850–900 ° C with currents of more than 3 MHz at a rate in the range of phase transformations of 100–200 ° C / s and hardening in oil or molten salt nitre at 170- 220 ° C, which provides a structure consisting of fine martensite and carbides.
Способ проверен при индукционной закалке надфилей всех тнноразмеров на FQCT 1513-67. В результате отработки но описываемому способу достигнута сцепл емость по всей рабочей части надфилей с контрольной пластинкой с 54.The method was tested during induction hardening of the file of all sizes on FQCT 1513-67. As a result of testing, the method described has achieved adhesion throughout the entire working part of the file with the control plate with 54.
Предлагаемый способ позвол ет автоматизировать процесс индукционной закалки широкого сортамента надфилей благодар равномерности закалки по длине инструмента.The proposed method allows to automate the process of induction hardening of a wide range of needle file due to the uniformity of hardening along the tool length.
Предмет изобретени Subject invention
Снособ индукционной закалки HHCTjpyMenTa, например надфилей, включающий нагрев токами высокой частоты и охлаждение в закалочной среде, отличающийс тем, что, с целью новышени равномерности закалки по длине инструмента, нагрев производ т при частоте тока более 3 мгц.The HHCTjpyMenTa induction hardening method, for example, a file, including heating with high frequency currents and cooling in a quenching medium, characterized in that, in order to improve the quenching uniformity over the tool length, heating is performed at a current frequency of more than 3 MHz.
