Abstract
Изобретение относитс к металлургии и может быть использовано при термообработке штампов, преимущественно молотовых . Цель изобретени - повышение производительности процесса и уменьшение деформаций. Способ заключаетс в следующем . Штампы устанавливают в печь гравюрой вверх и производ т нагрев штампов под закалку. При этом хвостовик нагревают до температуры на 20-40°С ниже, чем гравюру. Затем штампы закаливают и провод т совмещенный отпуск гравюры и хвостовика штампа. 2 табл.The invention relates to metallurgy and can be used in the heat treatment of dies, mainly hammer ones. The purpose of the invention is to increase the productivity of the process and reduce deformations. The method is as follows. The stamps are installed in the furnace by engraving upwards and the stamps are made for hardening. In this case, the shank is heated to a temperature that is 20-40 ° C lower than the engraving. Then the stamps are quenched and the combined tempering of the engraving and the stamp shank is performed. 2 tab.

Изобретение относитс к металлургии и может быть использовано при термообработке штампов, преимущественно молотовых .The invention relates to metallurgy and can be used in the heat treatment of dies, mainly hammer ones.
Цель изобретени - повышение производительности процесса и уменьшение деформаций .The purpose of the invention is to increase the productivity of the process and reduce deformations.
Способ заключаетс в следующем.The method is as follows.
Штампы устанавливают в печь гравюрой вверх и производ т нагрев штампа под закалку. При этом хвостовик нагревают до температуры на 20-40°С ниже, чем гравюру, что достигаетс за счет менее интенсивного подвода тепла со стороны пода печи. После разогрева штампа провод т охлаждение штампа в масле и совмещенный отпуск гравюры и хвостовика штампа.The stamps are installed in the furnace by engraving upwards and the stamp is heated for quenching. At the same time, the shank is heated to a temperature that is 20-40 ° C lower than the engraving, which is achieved due to less intensive heat supply from the furnace bottom. After the stamp is heated, the stamp is cooled in the oil and combined tempering of the engraving and the stamp shank.
Пример. Провод т обработку молотого штампа из стали 5ХНМ размерами 430x630x740 мм.Example. The processing of a ground punch from steel 5HNM with dimensions of 430x630x740 mm is carried out.
В табл. 1 показаны режимы термической обработки штампов; в табл. 2 - сравнительные данные предложенного и известного способов.In tab. 1 shows the heat treatment of the dies; in tab. 2 - comparative data of the proposed and known methods.
Как следует из табл. 1 и 2, обработка по предложенному способу позвол ет сократить врем и расход энергии на термообработку и уменьшить деформации штампа.As follows from the table. 1 and 2, the treatment according to the proposed method makes it possible to reduce the time and energy consumption for heat treatment and to reduce the deformation of the punch.
