Низкая стойкость инструмента приводит к повышению стоимости готовых изделий, увеличению трудовых и материальных затрат на замену изношенного инструмента и его наладку, снижению производительности прессового оборудования и повышению количества бракованной продукции. Представлена методика теоретического исследования для решения задачи по расчету температурного поля штампового инструмента при лазерной обработке. Составлено дифференциальное уравнение для численного решения поставленной задачи. Предложены режимы лазерной термообработки пуансона для пробивки отверстий и штампового инструмента из стали повышенной твердости. Натурные испытания, проведенные в промышленных условиях, показали, что рекомендованные режимы лазерной термообработки позволили повысить стойкость пуансона, предназначенного для пробивки отверстий, в 2 – 3 раза, а стойкость вырубных штампов в 2,2 – 2,8 раз.</p></abstract><trans-abstract xml:lang="en"><p>The article is devoted to improving the wear resistance of forging tools, in particular punches for punching holes and cutting stamp dies. Low tool life leads to an increase in the cost of finished products, an increase in labor and material costs for replacing worn tools and adjusting them, a decrease in the productivity of pressing equipment and an increase in the number of defective products. A method is presented for theoretical research of solving the problem of calculating the temperature field of a stamp die tool during laser processing. A differential equation was compiled for a numerical solution of the problem. The authors proposed the modes of laser heat treatment of a punch for punching holes and a stamp die tool made of high-hardness steel. Field tests conducted in industrial conditions showed that the proposed laser heat treatment modes made it possible to increase resistance of the punch intended for punching holes by 2 – 3 times and the resistance of the stamp dies by 2.2 – 2.8 times.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>кузнечно-прессовое производство</kwd><kwd>поле температур</kwd><kwd>пуансон</kwd><kwd>штамп</kwd><kwd>лазер</kwd></kwd-group><kwd-group xml:lang="en"><kwd>press forging</kwd><kwd>temperature field</kwd><kwd>punch</kwd><kwd>stamp die</kwd><kwd>laser</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Рогов В.А., Позняк Г.Г.
