硬质合金可转位钻头刀体的热处理工艺仿真研究

Simulation Study on Heat Treatment Deformation of Indexable Carbide Drill's Body

基于热处理基本原理和热弹塑性理论,采用有限元的方法,建立了硬质合金可转位钻头刀体热处理分析模型,利用DEFORM软件模拟了热处理过程中刀体温度变化规律、刀体残余应力分布情况,以及刀体变形大小和方向,为优化热处理工艺提供参考,同时刀体的变形量结果能够为后续的精加工工序确定适当的余量,避免过大的余量造成材料浪费和加工困难。

Based on the principle of heat treatment and the theory of thermo-elasto-plasticity,a finite element model is established for the heat treatment analysis of carbide indexable drill's body.The simulation is conducted in Deform software,and the results of temperature variation,the residual stress distribution and the deformation of the cutter body are obtained.These results provide a reference for optimizing the heat treatment process.,The deformation results of the cutter body can be used to determine the cutting allowance of the subsequent finishing process,and reduce the material waste and difficulty in hard cutting.
