摘要: 为研究机床用于维持热平衡的冷却能耗,更准确地揭示机床能效提升潜力,对干切机床及其冷却系统进行了分析,提出了机床效率评价指标,建立了综合考虑材料去除能耗和冷却能耗的效率评价模型,并以高速干切滚齿加工为例,验证了该模型的可行性与可靠性。研究结果表明,高速干切滚齿机床冷却设备的效率均在30%以下,且损失率高;为提高机床能效,需降低空气过滤器和空气压缩站的损失,提高空气压缩站和液压站的效率。该研究可为干切机床精密绿色运行的评价与节能优化提供理论支持。

Abstract:  To study the cooling energy consumption used to keep the heat balance of machine tools and to more accurately reveal the potential in energy efficiency improvements for machine tools, the exergy analysis of dry-cutting machine tools and their cooling systems was analyzed, and exergy efficiency indicators of machine tools were proposed. An exergy efficiency evaluation model of machine tools was established considering the energy consumption for material removal and cooling, and the feasibility and reliability of this model were verified with the case study of high-speed dry gear hobbing. The results show that exergy efficiencies of all the cooling devices for high-speed dry gear hobbing machine tools are below 30% and the exergy losses are high. In order to improve the energy efficiency of machine tools, the exergy losses of the air filters and the air compression stations should be reduced, the exergy efficiency of the air compression stations and the hydraulic stations should be increased. This paper may provide theoretical support for the evaluation and energy-saving optimization of the precision green operations for dry-cutting machine tools. 

Key words:  , exergy efficiency, cooling energy consumption, dry-cutting machine tool, evaluation model, green manufacturing.
