Изобретение относитс к машиностроению , в частности к поверхностному пластическому деформированию (ПГЩ деталей машин с целью повьшени их сопротивлени усталости.The invention relates to mechanical engineering, in particular to surface plastic deformation (PGSch machine parts with the aim of increasing their fatigue resistance.
Цель изобретени - повьппение эффективности упрочнени за счет увеличени сопротивлени усталости. Поставленна цель достигаетс .The purpose of the invention is to increase the effectiveness of hardening by increasing fatigue resistance. The goal is achieved.
тем, что предлагаемый способ обработки плоских деталей гарантирует осуществление обработки по оптимальным режимам. При этом максимум сопротивлени усталости соответствует глубине наклепанного сло , равной 0,09-0,12 толщины детали, и эта величина сильно зависит от свойств (твердости) стали. Поэтому измерение твердости вл етс необходимым дл реализации способа. Далее регулирование глубины наклепа осуществл етс путем специального выбора усили обкатки.the fact that the proposed method of processing flat parts ensures the implementation of processing in optimal conditions. In this case, the maximum fatigue resistance corresponds to the depth of the work-hardened layer equal to 0.09-0.12 of the thickness of the part, and this value strongly depends on the properties (hardness) of the steel. Therefore, a hardness measurement is necessary to implement the method. Further, the depth of work hardening is controlled by a special selection of the running force.
Способ осуществл етс следующим образом.The method is carried out as follows.
Перед обкаткой измер ют поверхностную твердость детали и опредеBefore running in, measure the surface hardness of the part and determine
л ют величину твердости по шкале Бринел . Затем согласно предлагаемому способу назначают глубину наклепа 8, равную 0,09-0,12 толщины детали . По указанным формулам вычисл ют усилие обкатки или энергию удара в зависимости от примен емого метода пластического деформировани , Пластическое деформирование ведут по рассчитанным режимам, при этом глубина наклепа приблизительно равна заданной величине (0,09-0,12) толщины детали. Коэффициент К, учитывающий состо ние структуры сталей, например дл ферритоперлитных, равен 1, а дл высокопрочных термически улучшенных конструкционных сталей ,25.Brinell hardness values are given. Then, according to the proposed method, the depth of work-hardening is 8, equal to 0.09-0.12 of the thickness of the part. According to these formulas, the rolling force or impact energy is calculated depending on the plastic deformation method used. Plastic deformation is carried out according to the calculated modes, and the depth of work is approximately equal to the specified value (0.09-0.12) of the part thickness. The coefficient K, which takes into account the state of the structure of the steel, for example, for ferritic perlite, is equal to 1, and for high-strength thermally improved structural steels, 25.
Применение предлагаемого способа позвол ет обеспечить значительное повышение усталостной прочности деталей в результате упрочнени , снизить энергетические затраты при выполнении упрочнени путем правильного выбора усили , уменьшить расход металла на изготовление упрочн емых деталей.The application of the proposed method allows to provide a significant increase in the fatigue strength of parts as a result of hardening, to reduce energy costs when performing hardening by the correct choice of effort, to reduce the metal consumption for the manufacture of hardened parts.
