Abstract
Изобретение относитс к инструментальному производству, в частности к термической обработке резцов из быстрорежущей стали. Цель изобретени - повышение ударной в зкости, эксплуа- тационной стойкости и ускорение процесса термообработки. Строгальные резцы из стали Р6М5ФЗ подвергали нагреву под закалку до 1230°С, выдержке , охлаждению в масле до 80-140°С, выдержке и нагреву до 620±10°С с регламентированной скоростью 60-180°С/м, выдержке и охлаждению на воздухе. Отпуск проводили 1 раз при 560°С 1 ч. Стоимость резцов при строгании сплава 36HXTIO возросла в 1,5 раз при снижении времени на термообработку в 2,5 раза. 1 табл.The invention relates to toolmaking, in particular to the heat treatment of high-speed steel cutters. The purpose of the invention is to increase the toughness, service resistance and accelerate the heat treatment process. Planing cutters made of steel R6M5FZ were subjected to heating for quenching to 1230 ° C, holding, cooling in oil to 80-140 ° C, holding and heating to 620 ± 10 ° C with a regulated speed of 60-180 ° S / m, exposure and cooling in air. Vacation was carried out 1 time at 560 ° C for 1 hour. The cost of the cutters when planing an 36HXTIO alloy increased 1.5 times while reducing the time for heat treatment by 2.5 times. 1 tab.

Изобретение относитс к инструмен- ,тальному производству, в частности к .термической обработке резцов из быстрорежущей стали.The invention relates to tool manufacturing, in particular to the thermal treatment of high-speed steel cutters.
Цель изобретени - повышение ударной в зкости, эксплуатационной стойкости и ускорение процесса термообра- ботки.The purpose of the invention is to increase the toughness, operational durability and acceleration of the heat treatment process.
Изобретение иллюстрируетс примерами , приведенными в таблице.The invention is illustrated by the examples in the table.
Из стали Р6М5ФЗ изготавливали строгальные резцы и подвергали термообработке по режиму:R6M5FZ steel was used for making planing cutters and subjected to heat treatment according to the following mode:
Подогрев до, С 850 Врем , мин3Heating up, With 850 Time, min3
Окончательный нагрев под закалку до, °С . 1230 выдержка 10 с на 1 мм толщины, охлаждение в масле до 80-l40ftC, выдержкаFinal heating for quenching to, ° C. 1230 extract 10 s per 1 mm thickness, cooled in oil up to 80-l40ftC, excerpt
2 мин, нагрев до отпуска 620+10°С со скоростью 60-180 С/мин проводили как в соли, так и на воздухе, выдержка 30 мин и охлаждение на воздухе. Отпуск 1 раз при 560°С, 1 ч, охлаждение на воздухе2 minutes, heating to temp. 620 + 10 ° С with a speed of 60-180 C / min was carried out both in salt and in air, aging for 30 minutes and cooling in air. Vacation 1 time at 560 ° С, 1 h, air cooling
Резцы изготавливали и испытывали при строгании сплава 36НХТЮ с при глубине строгани 1,5 мм, подаче 0,3 им, длине пути резца 120 мм.The cutters were made and tested when planing an alloy of 36NHTY with a planing depth of 1.5 mm, a feed of 0.3 to them, a cutting path of 120 mm.
Внедрение изобретени позвол ет существенно повысить производительность процесса, при этом количество инструмента значительно возрастает.The implementation of the invention significantly improves the productivity of the process, while the number of tools increases significantly.
