Забезпечення високої міцності різців з твердосплавними вставками на основі комп’ютерного моделювання індукційного паяння

Abstract

A computer model of induction brazing of carbide cutters is presented. With this model numerical studies of a temperature field in a carbide insert and in a body of the cutter in the process of soldering the insert to the body are performed. For the process of induction brazing of cemented carbide tools optimum configuration of an inductor and the heating conditions are determined which ensure high wear resistance and strength of the cutters after their subsequent hardening. The results of calculations of the temperature distribution in the volume of a cutter and the curves of the change in temperature at control points of a cutter are given.
