3D打印感应线圈的形状及构型对零件淬火性能影响的研究

Research on the Influence of Shape and Configuration of 3D Printed Induction Coils on Component Quenching Performance

在传统感应加热系统中,加热铜感应线圈主要通过手工或机器对截面形状为圆形的铜感应线圈进行弯折获得。随着3D打印的发展,不同截面形状的铜感应线圈可以被打印出来。3D打印的铜感应线圈截面形状可以随意变化,结构尺寸精度高。以轴类零件作为研究对象,通过数值模拟分析感应加热,采用加热温度和加热均匀度两个评价标准分析不同截面和感应线圈间距的铜感应线圈的加热性能,确定了加热性能较好的尺寸参数的取值范围。实验结果表明,矩形感应线圈的加热性能较好。

In traditional induction heating systems,heating copper coils are mainly obtained by manually or mechanically bending circular cross-sectional copper coils.With the development of 3D printing,copper coils with different cross-sectional shapes can be printed.The cross-sectional shape of 3D printed induction copper coils can vary freely,and the structural dimensions have high precision.This paper focuses on axial components as the research object and analyzes the induction heating process through numerical simulation.Heating temperature and heating uniformity are used as two evaluation criteria to analyze the induction heating performance of copper coils with different cross-sections and coil spacings.The range of dimension parameters with better heating performance is determined,and experimental results also indicate that rectangular cross-section coils exhibit better heating performance.
