Description
Существующие методы экранировани -применение медных пробок, медных трубок и замазывани глиной-недостаточно предохран ют от перегрева прилегающие к отверсти м участки деталей, вследствие чего в этих участках возникают трещины, а металл имеет неудовлетворительные свойства.The existing shielding methods — application of copper plugs, copper tubes, and clay coating — do not sufficiently protect the parts of the parts adjacent to the holes from overheating, as a result of which cracks appear in these areas, and the metal has unsatisfactory properties.
В описываемом изобретении эти недостатки зстранены тем что в отверстие , подлежащее защите, устанавливают железный стержень соответствующего диаметра, на который касажена кругла или другой формы (в зависимости от конфигурации отверсти ) пластинка из листового железа толщиной 0,5-In the described invention, these shortcomings are due to the fact that in the hole to be protected, an iron rod of the appropriate diameter is installed on which a plate made of sheet metal with a thickness of 0.5 to 5 is applied to a round or other shape (depending on the hole configuration).
1,5 мм. Соотношение между диаметром пластинки и диаметром отверсти должно быть пор дка 1,2-2,5 в зависимости от условий нагрева и охлаждени .1.5 mm. The ratio between the plate diameter and the hole diameter should be in the order of 1.2-2.5, depending on the heating and cooling conditions.
Предмет изобретени Subject invention
Метод защиты от перегрева и образовани трещин в участках деталей , прилегающих к отверсти м при нагреве под закалку током высокой частоты, отличающийс тем, что в отверстие детали перед нагревом под закалку вставл етс металлический стержень с железной пластинкой .The method of protection against overheating and cracking in parts of the parts adjacent to the holes when heated for quenching with high frequency current, characterized in that a metal rod with an iron plate is inserted into the hole of the part before heating for quenching.
