Description
Известны способы нормализации под внутренним давлением впа нных в держатель пружин.Methods are known for normalization under internal pressure of the springs pressed into the holder.
Отличительна особенность описываемого способа нормализации трубчатых пружин манометров в напр женном состо нии состоит в том, что нанр жение создают посредством установки согнутой пружины на оправку, внешний диаметр которой больше внутреннего диаметра пружины . Такой способ нормализации трубчатых пружин манометров повышает стабильность механических свойств пружин и увеличивает срок службы манометров.A distinctive feature of the described method of normalizing tubular springs of pressure gauges in the stressed state is that the design is created by mounting the bent spring on the mandrel, the outer diameter of which is larger than the inner diameter of the spring. This method of normalization of tubular springs of pressure gauges increases the stability of the mechanical properties of the springs and increases the service life of pressure gauges.
Процесс изготовлени латунных пружин манометров состоит из резки исходной манометрической трубки на заготовки и гибки заготовок , с целью придани им круглой формы. Затем пружины (заготовки) манометров подвергают нормализации.The process of manufacturing the brass springs of pressure gauges consists of cutting the initial pressure tube into blanks and bending the blanks to give them a round shape. Then the spring (workpiece) gauges are subjected to normalization.
Сущность процесса пормализации заключаетс в том, что трубчатые пружины, с целью придани им упругонапр женного состо ни , помещают сначала на цилиндрическую оправку, внешний диаметр которой больше внутреннего диаметра трубчатых пружин. При этом деформаци пружин должна быть упругой.The essence of the process of pormalization is that the tubular springs, in order to impart an elastically stressed state, are first placed on a cylindrical mandrel whose outer diameter is larger than the inner diameter of the tubular springs. In this case, the deformation of the springs must be elastic.
Затем трубчатые пружины манометров в упрутонапр женном состо нии вместе с оправкой подвергают нормализации в печи при оптимальной температуре, равной примерно 200°.Then, the tubular springs of the pressure gauges, in an elastically stressed state, together with the mandrel, are normalized in a furnace at an optimum temperature of about 200 °.
Предмет изобретени Subject invention
Способ нормализации трубчатых пружин манометров в напр женном состо нии, отличающийс тем, что, с целью повышени стабильности механических свойств пружин и увеличепи срока службы манометров, напр жение создают путем установки согнутой прулсины на оправку, внешний диаметр которой больше внутреннего диаметра пружины.The method of normalizing the tubular springs of the pressure gauges in the stressed state, characterized in that, in order to increase the stability of the mechanical properties of the springs and increase the service life of the gauges, the voltage is created by mounting the bent prulsine on the mandrel, the outer diameter of which is greater than the internal diameter of the spring.
