Description
Известен способ правки турбинных и компрессорных лопаток, заключающийс в том, что заготовку устанавливают в секционных, фиксирующих ее по определенным сечени м ложементах и нагружают посто нной нагрузкой, обеспечивающгй пластическое деформирование заготовки (1).There is a known method of straightening turbine and compressor blades, which means that the billet is installed in sectional locks fixing it over certain sections and loaded with a constant load, which ensures plastic deformation of the billet (1).
С целью повышени качества правки, заготовку в процессе приложени посто нной нагрузки нагревают в поперечных сечени х, рас1юложенных между поперечными сечени ми, зафиксированными в ложементах до температуры, обеспечивающей сверхпластическое состо ние металла заготовки.In order to improve the quality of the straightening, the billet is heated during the application of a constant load in cross sections that lie between the cross sections fixed in the cradle to a temperature that ensures the superplastic state of the metal of the billet.
Нагрев провод т последовательно, начина от сечени большей площади и конча сеюнием меньшей площади, после чего заготовку охлаждают до температуры, равной 0,6 температуры, обеспечивающей сверхпластическое состо ние металла заготовки.Heating is carried out sequentially, starting from a larger cross-section and ending with a smaller area of sowing, after which the billet is cooled to a temperature equal to 0.6, which ensures the superplastic state of the billet metal.
Недостатками существующего способа вл етс необходимость обеспечени жестких температурно-скоростных условий обработки лопаток , при которых имеет место сверхпластическое состо ние. Последовательное проведениеThe disadvantages of the existing method are the necessity of providing harsh temperature-speed conditions for the treatment of blades under which a superplastic state takes place. Sequential holding
нагрева штамповки, начина от сечени большей площади и конча сечением меньшей площади, снижает производительность труда. Необходимость охлаждать заготовку до температуры 0,6heating stamping, starting from a larger cross-section and ending with a smaller cross-section, reduces productivity. The need to cool the workpiece to a temperature of 0.6
от температуры, обеспечивающей сверхпластическое состо ние металла, вызьшает необходимость в наличии специальной установки.from temperature, providing a superplastic state of the metal, necessitates the presence of a special installation.
Известно устройство дл штамповки деталей , содержащее пуансон и матрицу 2.A device for stamping parts containing a punch and a die 2 is known.
Однако оно не обеспечивает деформировани деталей одновременно с злектрокоитактным нагревом.However, it does not warp parts at the same time as electro-stroke heating.
Целью изобретени вл етс повьшюние качества детали и обеспечение возможности ееThe aim of the invention is to improve the quality of the part and ensure its
электроконтактного нагрева при деформировании .electric contact heating during deformation.
Это достигаетс тем, что. перед тфавкой производ т высокотемпературную термическую обработку, например закалку или отжиг, а после правки деталь охлаждают с той жескоростыо, что и при термичгской обработке. При зтом нагрев детали производ т электроконтактнымThis is achieved by the fact that. High temperature heat treatment, such as quenching or annealing, is performed before tfukka, and after editing, the part is cooled with the same speed as during thermal processing. In this case, the heating of the part is performed by electrocontact
методом.method.
