【摘要】：针对单层钎焊超硬磨料成形砂轮感应加热时存在的温度分布不均匀问题,文中提出将砂轮成形面简化为相应特征成形面进行研究,借助FLUX有限元仿真软件,重点分析了线圈与导磁体的结构尺寸对凹、凸两类特征面感应加热时温度分布的影响规律,进而以燕尾槽形单层超硬磨料成形砂轮为对象,优化了钎焊用感应器结构.采用优化的感应器结构对燕尾槽型成形砂轮进行感应加热试验,利用红外热像仪测量成形面的温度分布.结果表明,该方法得到的感应器结构能够有效提高成形面超高频感应加热温度分布的均匀性,成形面各处温差在50℃以内.
[Abstract]:Aiming at the problem of uneven temperature distribution in induction heating of single layer brazing superhard abrasive grinding wheel, the paper proposes to simplify the forming surface of grinding wheel to corresponding characteristic forming surface, and makes use of FLUX finite element simulation software. The influence of the structure size of coils and magnetic conductors on the temperature distribution during induction heating of concave and convex characteristic surfaces is emphatically analyzed, and the structure of the inductor for brazing is optimized by taking the single layer superhard abrasive grinding wheel with swallowtail groove as the object. The induction heating test was carried out on the swallowtail groove shaped grinding wheel with the optimized inductor structure, and the temperature distribution of the forming surface was measured by infrared thermal imager. The results show that the inductor structure obtained by this method can effectively improve the uniformity of the temperature distribution of ultra-high frequency induction heating on the forming surface, and the temperature difference between the different parts of the forming surface is less than 50 鈩，
