传统金刚石圆锯片的有效切割宽度只有其直径的30~35%。为在普通规格的金刚石圆盘锯上低成本、高效率的加工大幅面石材制品,本文基于创新设计原理和圆锯片、锯机结构与功能的分析,将圆锯片分解为切割功能模块、支撑功能模块和驱动功能模块,提出新型组合式金刚石圆锯片基体的设计方案,使圆锯片的切割幅面达到其直径的2/3。应用有限元分析软件ANSYS,在结构分析、模态分析的基础上对组合式金刚石圆锯片基体径厚比、切割功能模块尺寸进行优化设计。结果表明:结构优化后的Φ1800mm组合式金刚石圆锯片基体质量减轻3.048kg,一阶固有频率提高3.235Hz,圆锯片直径和厚度均有所降低,动态性能更加稳定,结构更加合理。
The effective cutting width of the traditional diamond saw blade is only 30 to 35% of its diameter. In order to reduce the cost and efficiency of machining large format stone products on the ordinary circular diamond saw, this paper, based on the principle of innovative design and the analysis of the structure and function of the circular saw and saw, divides the circular saw into the cutting function module, Support function module and drive function module, put forward a new type of composite diamond saw blade substrate design, the circular saw blade cutting breadth to reach 2/3 of its diameter. The finite element analysis software ANSYS was used to optimize the design of the diamond-saw blade substrate diameter-thickness ratio and cutting function module size based on the structural analysis and modal analysis. The results show that the structural quality of Φ1800mm diamond saw blade is 3.048kg, the first natural frequency is increased by 3.235Hz, the diameter and thickness of circular saw blade are reduced, the dynamic performance is more stable and the structure is more reasonable.
