Вибрационные колебания в технологических процессах упрочнения

Abstract

В статье рассматриваются вопросы применения вибрационных колебаний в технологических процессах восстановления и упрочнения деталей машин.

This article discusses the use of the vibration in the various processes in the reduction of (manufacturing) working organs of the car and provides examples. Peculiarities of the vibration treatment of proven machine components and reveals the mechanism of the vibration exposure of vibration waves on the structure of the processed material, altering the level of residual stresses. We investigated and the optimal values of the following parameters: frequency of oscillation of the machining tool, its oscillation amplitude, hardening time, justified the parameters of the cutting edge plowshare, the disc coulter grain drill. Research has identified the law of variation of geometrical parameters of working organs of tillers. The advantages of surface plastic deformation by mechanical vibrations of the machining tool can significantly improve the durability of these parts at the expense of physical and mechanical condition of the properties of the treated surface, which increases the life of machines. The effect of deformation of the vibration on the value of compressive residual stresses of the processed material, have an impact on its strength characteristics. The recommendations on the choice of optimal technological parameters of the hardening of the vibration treatment is functional relationship to determine the degree of hardening, which is calculated on the basis of its value in the normal vibration and deformation. Research has established that the degree of hardening of the material disc coulter recovered segmental tire welding with subsequent vibratory welding deformation Sormayt at 1.4 times greater than in conventional processing.
