Description

(54) СПОСОБ ТЕРМИЧЕСКОЙ ОБРАБОТКИ МОЛОТОВЫХ(54) METHOD FOR THERMAL TREATMENT OF MOLOTOVA

ШТАМПОВSTAMPS

ше критической точки Ас на SO-IOO-C. Гакой нагрев вызывает в наиболее опасных местах штампа образование аус1енита, который затем 1 процессе выполнени  последующего нагрева штампа подвергаетс  перлитному превращению. Благодар  этому обеспечиваетс  надлежаща  подготовка структуры к закалке.above the critical point Ac on SO-IOO-C. This heating causes, in the most dangerous places of the stamp, the formation of austenite, which is then subjected to pearlite transformation by the process of the subsequent heating of the stamp. This ensures that the structure is properly prepared for hardening.

Способ осушествл етс  следуюишм образом .The method is carried out in the following manner.

Штампы загружают в печь, имеющую температуру 60О-650°С. После прогрева штампы выгружают из печи и устанавливают поочередно на стол индукционного устройства. Включают источник высок9частотного нагрева и нагревают зоны, в которых в процессе эксплуатации штампов возникают трещины. Нагрев производ т до температуры, выше критической точки Ас на 50-100°С. Затем штампы вновь загружают в печь и производ т их сквозной нагрев под закалку. После выдержки штампы подстуживают на воздухе до 750-78О°С / и закаливают. Вслед за закалкой от тем- : пературы охлаждени  {15О -2ОО°С) штам-; пы незамедлительно подвергают объемно- / му отпуску, а затем производ т отпуск ; хвостовика.Stamps are loaded into an oven having a temperature of 60 ° C to 650 ° C. After warming up, the dies are unloaded from the oven and set alternately on the table of the induction device. They include a source of high-frequency heating and heat zones in which cracks arise during the operation of the dies. Heating is performed to a temperature above the critical point Ac at 50-100 ° C. Then, the dies are reloaded into the furnace and they are heated through for quenching. After aging, the dies are pressed in air to 750-78 ° C / and quenched. Following quenching from the temperature: cooling (15 ° -2OO ° C) strain; The pulses are immediately subjected to volumetric tempering, and then the tempering is performed; shank

Использование предлагаемого способа ; термической обработки молотовых штам- Using the proposed method; heat treatment of hammerheads

пов позвол ет по сравнению с существую™ щим способом повысить эксплуатационный ресурс штампов за счет повышени  хрупкой прочности материала в местах зарождени  трещин. Опыты показали, что термическа  обработка, например стали 5ХНВ, по предлагаемому способу повышает работу излома в 1,5-2 раза.As compared with the existing method, it allows to increase the operational life of the dies by increasing the brittle strength of the material in the places of cracking. Experiments have shown that heat treatment, for example, steel 5HNV, according to the proposed method, increases the fracture performance by 1.5-2 times.
