Изобретение относитс  к области изготовлени  и испытани  пружин, а именно к способам повышени  качества и рабочих характеристик пружин методом заневоливани , и может быть применено в машиностроении, приборостроении и т. д.The invention relates to the field of manufacture and testing of springs, in particular, to methods for improving the quality and performance of springs by the method of seeding, and can be applied in mechanical engineering, instrument engineering, etc.

Известен способ контактного заневоливани  пружин характерный тем, что при приложении осевой нагрузки, привод ш,ей к возникновению остаточных напр жений как в витках, так и на поверхности витков, сжатой до соприкосновени  витков пружине придаетс  правильна  геометрическа  форма путем взаимодействи  ее наружного диаметра со втулкой приспособлени , а торцев ее витков с вкладышами, повтор юшими форму торца витка пружины 1.The known method of contact spring-uping of springs is characteristic in that when an axial load is applied, the drive W is responsible for the appearance of residual stresses both in the coils and on the surface of the coils, the spring is attached to the correct geometrical shape by the interaction of its outer diameter with the sleeve of the device , and the ends of its turns with inserts, repeat the shape of the end face of the spring 1.

Этот способ заневоливани  пружин позвол ет увеличить их стойкость по сравнению с обычным заневоливанием в 1,5 раза.This method of springing up the springs allows increasing their durability by 1.5 times as compared with conventional springing up.

Недостатком известного способа  вл етс  то, что увеличенные остаточные напр жепи , обуславливаюш,ие увеличенную осадку пружины , неравномерно распределены по сечению витка и имеют место преимуш,ественно в лиНИИ контакта витков между собой, что способствует созданию концентраций напр жений в пружине, что служит предпосылкой к поломке пружины в изделии.The disadvantage of this method is that the increased residual stresses causing the spring draft to increase, are unevenly distributed over the cross section of the coil and are prevalent in the line between the contact of the coils between them, which creates the concentration of stresses in the spring. to break the spring in the product.

С целью повышени  качества пружин путем In order to improve the quality of the springs by

равномерного распределени  остаточных напр жений по диаметру витка пружины по предлагаемому способу к пружине одновременно с осевой нагрузкой прикладывают также по оси вибрационную нагрузку.evenly distributing residual stresses across the diameter of the spring coil according to the proposed method, a vibration load is also applied to the spring simultaneously with the axial load.

Дл  уменьшени  разброса снловых параметров пружины от номинала производ т повторное нагружение пружины с усили ми, увеличенными относительно первоначальных пропорционально отношению требуемой осадк;. пружины к осадке от иервичного приложени  нагрузок.To reduce the variation in the spring parameters from the nominal, the spring is re-loaded with forces increased from the initial proportional to the ratio of the required sediment ;. springs to draft from primary loading.

Ири этом осева  нагрузка вызывает остаточные напр жени  как в линии контакта витков , так и внутри их, а вибрационна  осева  нагрузка способствует равномерному распределению остаточных напр жений по сечению витков, ириводит к пластической деформации в виде поверхпостного наклепа, при котором достигаетс  увеличение нрочности, понижение склонности ко всем видам хрупких разрушений и создание благопри тных сжимающих поверхностных напр жений. При этом процесс п.гастической деформации пружины занимает несколько секунд. Врем  выдержки пружины над нагрузкой определ етс  возможност ми примен емого оборудовани  и не превышает 10-30 с.In this way, the axial load causes residual stresses both in the contact line of the coils and inside them, and the vibrational axial load contributes to a uniform distribution of the residual stresses over the cross section of the coils, leading to plastic deformation in the form of surface resistance, at which an increase in northeasternity is achieved, and the tendency is reduced to all kinds of brittle fractures and the creation of favorable compressive surface stresses. At the same time, the process of operating the deformation of the spring takes several seconds. The hold time of the spring over the load is determined by the capabilities of the equipment used and does not exceed 10-30 s.
