大直径薄片状叶轮是喷丸器总成的重要部件。我公司在自制叶轮过程中,由于受到热处理压淬设备生产瓶颈的制约,多年来一直采用常规热处理淬火工艺规范,热处理后端面翘曲畸变量大,不良品率达到100%,经磨削加工后仍达不到图纸技术要求。叶轮几何精度差,既影响组装后的静平衡调试,又 Large-diameter flake impeller is an important part of the shot peening assembly. In the process of self-made impellers, due to the restriction of the bottleneck of the heat-treatment equipment for pressure-quenching, the conventional heat-treatment quenching process has been adopted for many years. After the heat treatment, the distortion of the warpage of the end face is large and the defective rate reaches 100%. After grinding, Still can not meet the technical requirements of drawings. Impeller geometric accuracy is poor, both affect the static balance after commissioning, and
