摘要:
提高刀辊材料硬度可减少磨损，延长其使用寿命，提高模切速度，但会导致与之配合的砧辊损伤更为严重。为了使刀辊和砧辊系统总磨损量达到最小，试验研究了刀辊和砧辊的硬度匹配问题。利用滚动磨损试验机研究了刀辊与砧辊的硬度匹配，分析了不同硬度刀辊与砧辊匹配时的摩擦磨损与表面损伤行为。结果表明：不同硬度刀辊和砧辊试样匹配对滚动摩擦系数基本无影响；随刀辊硬度增加，刀辊磨损量呈下降趋势，砧辊磨损量表现为线性增加，刀辊和砧辊总磨损量呈先降低后增加的趋势，当刀辊与砧辊硬度比为1.016时，刀辊和砧辊系统总磨损量达到最小。刀辊硬度对刀辊和砧辊试样表面损伤形貌没有影响，刀辊和砧辊试样表面损伤形貌均表现为表面剥落损伤机制。
Abstract:
Increaing the hardness of knife roller material can reduce the knife roller’s wear, prolong its service life and improve its cutting speed, but it might result in more serious damage of the matched anvil roller. To minimize the overall wear of the knife roller and the anvil roller, the hardness matching of the knife roller and the anvil roller was researched via rolling wear testing machine. The friction wear and surface damage behaviours of the knife roller and the anvil roller samples matched under different hardnesses were analysed. The matching of the knife roller and anvil roller samples under different hardness had no effect on rolling friction coefficient. The knife roller’s wear decreased with the increase of the roller’s hardness while the wear of the anvil roller increased linearly. The overall wear of the knife roller and the anvil roller samples decreased but then increased. When the hardness ratio of the knife roller to the anvil roller is 1.016, the overall system wear of the knife roller and the anvil roller minimized. The knife roller’s hardness had no effect on the surface damage morphology of both the knife roller and anvil roller samples, with the damage samples’morphology showing surface spalling damage mechanism.
