Description
Изобретение относитс к области машиностроени , в частности, к .способу поверхностного упрочнени металлических деталей.The invention relates to the field of mechanical engineering, in particular, to a method of surface strengthening of metal parts.
Известны способы упрочнени поверхности деталей, по которым после местного нагрева поверхность деформируют при помощи накатных роликов, после чего охлаждают. Такие способы «е обеспечивают в р де случаев потребного качества упрочнени из-за неравномерности охвата поверхности упрочн ющими элементами и сосредоточенности нагрузки, а также затрудн ют подбор деформирующих элементов и релулировку давлени , что сказываетс на производительности работы.Methods are known for hardening the surface of parts, by which, after local heating, the surface is deformed by means of rolling rollers, and then cooled. Such methods do not provide, in a number of cases, the required quality of reinforcement because of the unevenness of the surface coverage by the reinforcing elements and the load concentration, and also make it difficult to select the deforming elements and relieve the pressure, which affects the productivity.
Более равномерна обработка поверхности и упрощение технологии обеспечиваютс за счет того, что после нагрева поверхность детали деформируют при помощи рабочей жидкости, которую направл ют струйно под высоким давлением, не ниже 200 атм.A more uniform surface treatment and simplification of the technology are provided due to the fact that after heating the surface of the part is deformed with the help of a working fluid, which is jetted under high pressure, not lower than 200 atm.
Способ осуществл етс следующим образом .The method is carried out as follows.
Подвергающуюс упрочнению поверхность нагревают до заданной температуры, затемThe hardening surface is heated to a predetermined temperature, then
направл ют жидкость под высоким давлением несколькими стру ми, после чего поверхность охлаждают, обеспечива непрерывность и последовательность указанных операций.high pressure liquid is directed by several jets, after which the surface is cooled, ensuring continuity and consistency of these operations.
Обработанна так металлическа деталь пе имеет остаточных деформаций из-за снижени изгибающих напр жений от деформирующего элемента и более равномерно упрочпена . Кроме того, предлагаемый способ позвол ет расщирить типоразмеры обрабатываемых деталей.The treated metal part has no residual deformations due to a decrease in the bending stresses from the deforming element and is more evenly strengthened. In addition, the proposed method allows to expand the sizes of the parts to be machined.
Предмет изобретени Subject invention
Способ термомеханической поверхностной обработки металлов, в котором металлическ|ую деталь последовательно нагревают, затем унрочн ют ее поверхность, после чего охлаждают, отличающийс тем, что, с целью улучшени качества упрочнени и повышени производительности, упрочнение поверхности производ т рабочей жидкостью под давлением не менее 200 атм.The method of thermomechanical surface treatment of metals, in which the metal part is sequentially heated, then strengthened its surface, and then cooled, characterized in that, in order to improve hardening quality and increase productivity, surface hardening is produced by working fluid under pressure of at least 200 atm
