| 摘 要： | 针对加工大幅面石材制品的市场需求，提出一种切割幅面达到其直径2／3的新型组合式金刚石圆锯片基体，并对其进行了结构、功能分析。针对圆锯片基体的适张处理，在考虑切削热影响的情况下，应用ANSYS对新型组合式金刚石圆锯片基体进行应力、变形分析。结果表明：组合式金刚石圆锯片基体受温度影响较大，由于切削热的存在产生了较大的热应力和变形量，最大热应力发生在结块焊接处及节块外边缘。最大为315MPa。应力分析为基体的适张处理和稳定性设计提供理论依据和参考。

| Abstract: | A new combined diamond saw blade was brought forward for market demand of stone product,of which the cutting breadth can reach two thirds of its diameter.Structure and function analysis of the new combined saw blade were carried out.For tensity disposal of saw blade,the cutting heat was considered when analysing the stress and deformation of the new combined diamond saw blade by applying ANSYS.The results indicated that,the influence of temperature on combined diamond saw blade is more obvious than conventional diamond saw blade.Thermal stress and noticeable deformation were generated because of the cutting heat.The maximum stress was generated at the welding point and the edge of the segment,which reached to 315 MPa.Finally,the stress analysis offers theoretic foundation and reference for tensity disposal and stability design of saw blade. |
