摘　　要：针对传统拉削过程负载大,且传统切削液对环境有一定危害等问题,对绿色植物油切削液技术在拉削加工中的应用进行了研究。提出了将纯蓖麻油、玉米油、芝麻油、橄榄油和大豆油等5种植物油以及传统拉削油作为切削液的研究,利用微量润滑系统(MQL),将切削液喷射到了拉削加工区域;并以干拉削为对照,设计了拉刀前半段干拉、后半段油拉的实验方案;利用拉削实验系统,对切削液的性能进行了测试,通过对植物油分子结构的分析,研究了不同植物油对拉削负载和表面粗糙度的影响。研究结果表明:在5种植物油中,芝麻油有着最佳的拉削性能;相比于传统油拉削,应用微量润滑芝麻油可明显降低拉削负载,拉削负载图中的波峰和波谷均值分别提高了74.0%和63.2%,表面质量提高了22.1%;该研究结果有助于改善拉削性能,具有一定的实际应用价值。Aiming at the problems that the large load of traditional broaching process and the traditional cutting fluid has certain harm to the environment,the application research of the green vegetable oil cutting fluids in the broaching process was investigated.Conventional broac-hing oil and five vegetable oils such as pure castor oil,corn oil,sesame oil,olive oil and soybean oil were used as cutting fluids,and were sprayed into the broaching area by a minimum quantity lubrication(MQL)system.The experimental scheme of the dry broaching on front half of broach tool and the oil broaching on back half was designed by dry broaching as control.The performances of the cutting fluids were tested by the broaching experiment system.The effects of different vegetable oils on broaching load and surface roughness were studied by the molecular structure of vegetable oil.The results indicate that the application of sesame oil has the best broaching performance.In addition,compared with conventional broaching oil,the application of misco sesame oil ubricating can obviously reduce broaching load,and the aver-age value of wave peak and wave valley in broaching load chart is increased by 74.0%and 63.2%respectively,and the surface quality is increased by 22.1%.This helps to improve the broaching performance and it has practical application value.
