| 目的 为解决阀芯类零件节流边毛刺去除不均匀和效率低下的问题，对磁极板尺寸和曲率进行规律性研究和实验验证。方法 首先，用Maxwell仿真软件对磁极板的各个参数进行规律性仿真，得出合适的磁极板尺寸;其次，为提高加工区域的磁感应强度值，设计了曲面磁极板，并对其相关参数进行仿真;最后对优化后的装置进行磁感应强度测试，并使用液体磁性磨具对45钢和阀芯棱边毛刺进行去除实验。结果 根据仿真结果发现，磁极板长度比工件大20 mm时，工件轴向磁场分布最均匀，磁极板厚度对磁场影响较小，磁极板宽度应根据加工间隙进行选择。曲面磁极板可以加强加工区域的磁感应强度值，曲率半径越小，加工区域获得的磁感应强度值越大，其中半圆形磁极板效果最佳。对装置的磁感应强度测试也表明，将工件置于磁场中后，其表面磁感应强度值最高达600 mT左右，满足加工需求。最后通过加工实验发现，在转速为500 r/min的条件下，阀芯节流边的毛刺去除效果理想，且轴向加工均匀。结论 该装置可以对阀芯这类导磁性回转类零件产生良好的加工效果。 |

| The work aims to carry out regularity study and experimental verification on the size and curvature of magnetic pole plate to solve the non-uniformity and low efficiency in deburring of throttling edge of spool parts. Firstly, the Maxwell software was used to simulate the changes in different parameters of magnetic pole plate, and then the appropriate size of the magnetic pole plate was obtained. Secondly, in order to improve the magnetic induction intensity in the processing area, curved magnetic pole plate was designed, and the related parameters were simulated and analyzed. Finally, the magnetic induction intensity of the improved device was measured, and the edge burrs of 45 steel and spool were removed by fluid magnetic abrasive. According to the simulation results, when the length of the magnetic pole plate was 20 mm larger than the workpiece, the axial magnetic field distribution of the workpiece was the most uniform, and the thickness of the magnetic pole plate had little influence on the magnetic field. The width of the magnetic pole plate should be selected according to the machining gap. The magnetic induction intensity in the processing area could be enhanced by the curved magnetic pole plate. The smaller the radius of curvature was, the larger the value of magnetic induction intensity was, among which the semicircular magnetic pole plate had the best effect. The magnetic induction intensity test of device showed that after the workpiece was placed in the field, the magnetic induction intensity of the spool surface in the processing area could reach up to 600 mT, which met the processing requirements. Finally, it was found that when the speed of workpiece reached 500 r/min, the deburring effect of throttling edge of spool parts was ideal and the axial processing was even. The device has good processing effect on the magnetic rotating parts such as spool. |
