Description

(54) СПОСОБ ИЗВЛЕЧЕНИЯ. БЫСТРОРЕЖУШИХ ВСТАВОК(54) METHOD OF EXTRACT. QUICK INTERCUTS

Изобретение относитс  к обработке металлов давлением и может быть исполь зовано при переработке металлического лома, в частности отходов инструментального производства. Известен способ разделени  материало включающий закалку материала и последующее разделение l. Недостатком известного способа  в-л етс  то, что он не позвол ет раздел ть пластины из быстрорежущей стали от пластин из конструкционной стали .металлолома режущего инструмента. Известен также способ извлечени  быстрорежущих вставок из режущего ин- струмента путем отделени  быстрорежущих вставок от держател  из конструкционной стали f2j Этот способ не позвол ет качественно отдел ть инструментальную сталь от конструкционной из-за возникающих в процессе разделени  трудностей, так как НЕШИЧИ8 тугоплавких карбидов и окислов у быстрорежущей стали позвол ет вести разку только а некотором удалении от места стыка в сторону конструкционной стали, при этом быстрорежуща  сталь поступает на переработку уже не в чистом виде, а с остатками конструкционной стали; необходимость редварительного определени  места стыка быстрорежущей и конструкционн 5й стали, например, при помощи химического травлени . Целью изобретени   вл етс  повышение качества отделени . Это достигаетс  тем, что отделение осуществл ют путем нагрева до температуры , превышающей темпер&туру закалки быстрорежущей стали, и последующего охлаждени . Способ разделени  отходов составного режущего инструмента, состо щего из пластин быстрорежущей и конструкционной стали, производ т посредством термообработки , заключающейс  в нагреве до температуры , превышающей температуру закалки быстрорежущей стали нь менее, чем на 5О°С и резком охлаждении. ПриThe invention relates to the processing of metals by pressure and can be used in the processing of scrap metal, in particular tool production waste. A known method for the separation of materials includes the hardening of the material and the subsequent separation of l. A disadvantage of the known method is that it does not allow separating high-speed steel plates from structural steel plates of metal cutting tool of a cutting tool. There is also known a method of extracting high-speed inserts from a cutting tool by separating high-speed inserts from a holder of structural steel f2j. This method does not allow high-quality separation of tool steel from structural steel due to the difficulties encountered in the separation process, since high-speed steel allows to razku only a certain distance from the junction towards the structural steel, while the high-speed steel goes for processing no longer in pure form, and structural steel from residues; the need for preliminary determination of the junction point of high-speed and 5th structural steel, for example, by chemical etching. The aim of the invention is to improve the quality of the separation. This is achieved in that the separation is carried out by heating to a temperature above the quenching temperature of high-speed steel and subsequent cooling. The method of separating the waste of a composite cutting tool consisting of plates of high-speed and structural steel is carried out by heat treatment consisting in heating to a temperature above the quenching temperature of high-speed steel by less than 5 ° C and quenching.
