Description

Изобретение относитс  к способам термической обработки штамповых изделий.The invention relates to methods for heat treatment of die articles.

Известен способ термической обработки штамповых изделий, включающий сквозной нагрев издели  до температуры ниже точки Ась нагрев рабочей части до температуры выше точки Асз, охлаждение и отпуск.There is a method of heat treatment of die products, including through-heating the product to a temperature below the As point, heating the working part to a temperature above the Asz point, cooling and tempering.

Описываемый способ повышает износостойкость изделий. Дл  этого сквозной нагрев производ т до температуры в интервале Aci-Асз.The described method improves the wear resistance of products. For this end-to-end heating is carried out to a temperature in the Aci-Asz range.

Описываемый способ включает печной нагрев изделий, например штампов гор чей штамповки, в том числе и прошедших предварительную химико-термическую обработку, до температуры, лежащей в интервале между критическими точками Aci и Асз, выдержку при этой температуре дл  релаксации напр ,жений, индукционный нагрев пригравюрнои части до температуры выше точки Асз, выдержку дл  выравнивани  температуры, охлаждение в закалочной среде и последующий отпуск, что обеспечивает низкий уровень остаточных напр жений в штампах при значительном и стабильном упрочнении рабочей поверхности.The described method includes furnace heating products, such as hot stamping dies, including those that have undergone preliminary chemical-thermal treatment, to a temperature in the interval between critical points Aci and Asz, holding at this temperature for relaxation of stresses, induction heating parts to a temperature above the Asz point, a shutter speed to equalize the temperature, cooling in a quenching medium and subsequent tempering, which ensures a low level of residual stresses in the dies with significant and stable nom hardening of the work surface.
