中文摘要:
      目的 为解决当前粘弹性磁性磨具制备工艺复杂、使用寿命短且加工过程易分解等问题,研制一种以107硅橡胶为基体的粘弹性磁性磨具,并通过加工实验研究了粘弹性磁性磨具流动性、自身配比和加工转速对工件光整加工效果的影响。方法 选用新制备的粘弹性磁性磨具对铝合金管外圆表面进行光整加工实验,选取不同交联剂含量的新磨具对其进行加工实验,分析基体流动性对光整加工效果的影响;选取不同的工件转速进行加工实验,分析工转速对光整加工效果的影响;选取铁磁相和磨粒相比例不同的新磨具进行加工实验,分析铁磁相和磨粒相比例对粘弹性磁性磨具光整加工效果的影响;选取磨粒相粒径不同的新磨具进行加工实验,分析磨粒相粒径对光整加工效果的影响。结果 当107硅橡胶为20 g、羰基铁粉为15 g、碳化硅为5 g、甲基硅油为1 g、软化剂为1 g、交联剂为0.14 g、工件转速为350 r/min、磨粒相粒径为600目时,可将工件表面粗糙度值Ra由0.299 μm下降到0.113 μm,Ra值相对下降率约为62.2%,加工效果最好。结论 新制备的磨具有性能稳定、制备方便、可根据不同工况调整流动性等优点。

      The work aims to solve the problems of existing viscoelastic magnetic abrasive tools including complicated preparation technology, short service life and decomposition trend in finishing by developing a 107 silicone rubber-based viscoelastic magnetic abrasive tool, and studying the effects of the tool’s fluidity, self matching ratio and processing speed on finishing effect of workpiece through finishing experiments. Finishing experiments were applied to outer surface of aluminum alloy tube with newly prepared viscoelastic magnetic abrasive tool. The new abrasive tools with different content of crosslinking agent were selected for processing experiments to analyze the influence of substrate fluidity on finishing effect. Machining experiments were carried out at unequal workpiece speed to analyze the influence of workpiece speed on finishing effect. The new abrasive tools with different mass ratios of ferromagnetic phase and abrasive phase were selected for the machining experiments to analyze the influence of the mass ratio on the finishing effect. The new abrasive tools with different particle size were selected for the machining experiments to analyze the influence of abrasive particle size on the finishing effect. The workpiece surface roughness value Ra decreased from 0.299 μm to 0.113 μm, relative decrease rate of Ra value was about 62.2%, and the finishing effect was the best provided with 20 g 107 silicone rubber, 15 g carbonyl iron powder, 5 g silicon carbide, 1 g themethyl silicone oil, 1 g softener, 0.14 g crosslinking agent, 350 r/min workpiece speed and 600 mesh abrasive particle size. The newly prepared abrasive tools feature in stable performance, convenient preparation and mobility adjustment according to different working conditions.
