Claims (1)

Способ термической правки изделий, включающий установку изделия на оправку, поджатие ее прижимом через натяжной стержень крышкой, последующие нагрев и охлаждение, при этом коэффициенты линейного расширения оправки и прижима больше коэффициента линейного расширения детали и нажимного стержня, отличающийся тем, что при нагреве сначала выбирается начальный зазор, при этом создается определенное усилие сжатия для правки фланца изделия с одновременной калибровкой изделия в диаметральном направлении.The method of thermal dressing of products, including installing the product on the mandrel, pressing it with a cover through the tension rod by a lid, subsequent heating and cooling, while the linear expansion coefficients of the mandrel and pressure are greater than the linear expansion coefficient of the part and pressure rod, characterized in that the initial a gap, this creates a certain compression force for straightening the product flange while calibrating the product in the diametrical direction.
