Description
При закалке тел сложной конфигурации во lюrиx случа х тело может быть рассматриваемо как система, состо ща из р да цилиндров разного радиуса; в этом случае достаточно равномерный дл практики слой закалки может быть получен подбором частоты, определ емой меньшим радиусом цилиндрика. В р де же случаев нодбор частоты по этому принципу не может иметь места, напрнмер, тогда, когда тело имеет острые утлы, которые также должны подвергатьс закалке.During the hardening of bodies of complex configuration in the Lyuir cases, the body can be considered as a system consisting of a number of cylinders of different radii; In this case, the quenching layer, which is sufficiently uniform for practice, can be obtained by selecting the frequency determined by the smaller radius of the cylinder. In a number of cases, frequency selection by this principle cannot take place, i.e., when the body has sharp edges, which must also be quenched.
Казалось бы, что в этом случае мончно прин ть малый радиус г круга, вписанного в треугольник, представл юш,ип острый угол, равный 0°, и калить, пользу сь весьма высокой частотой, однако при этом может потребоватьс очень больша удельна мощность или настолько малое врем нагрева, что в закаливаемом слое не успеют произойти требуемые превращени .It would seem that in this case it would be monkish to take a small radius g of a circle inscribed in a triangle, representing ush, type an acute angle equal to 0 °, and kalit using a very high frequency, however, this may require a very high specific power or short heating time that the required transformations do not have time in the quenched layer.
Насто щее изобрете11ие дает решен;1е данной задачи.The present invention gives a solved; 1e of this problem.
Предлагаемый способ состоит в том, что нагрев под закалку прО 13водитс не на одном, а на двух или, в редких случа х, на нескольких сильно отлнчны.х частотах. Индуктор приключаетс сперва к источнику более низкой частоты, с тем чтобы получилс нагрев поверхности тела на нижнюю глубину. При этом обыч}{о острые углы в течение короткого отрезка времени нагрева не получают необходимой температуры нагрева . Непосредственно после этого в тот же ннлуктор зк.лючаетс на очень короткнй промежуток времени высока частота (пор дка 300000 гц или даже выше), и острый угол нолучает необходимую температуру нагрева . После этого путем охлажденн получают закалку.The proposed method consists in that heating for quenching is carried out not at one but at two or, in rare cases, at several very different frequencies. The inductor comes first to the source of a lower frequency so that the body surface is heated to a lower depth. In this case, the usual} {o acute angles do not receive the required heating temperature for a short period of heating time. Immediately thereafter, the same switch is switched on for a very short period of time, the frequency is high (on the order of 300,000 Hz or even higher), and the acute angle gains the required heating temperature. After that, quenching is obtained by cooling.
Можно вести процесс и в обратном пор дке, хот это и менее рационально . Можно включать разные частоты, пpн ieн один индуктор, или дл каждой частоты примен ть отдельный нндуктор. В последнем случае индуктор или тело перемещают.You can conduct the process in reverse, although it is less rational. Different frequencies can be switched on, since one inductor is not used, or a separate inductor is used for each frequency. In the latter case, the inductor or body is moved.
Наконец, возможно достижение того же эффекта путем создани в одном и том же индукторе одновременно двух частот; основной частоFinally, it is possible to achieve the same effect by creating two frequencies in the same inductor simultaneously; primary often
