【摘要】：针对国产带锯床设计中,普遍存在的锯架设计不合理导致锯条寿命短、锯切精度及效率不达标、制造成本高等问题,建立了带锯床锯架力学模型;以某型号锯床为实例,根据锯架力学模型对锯条进行了应力循环分析,建立了锯条的疲劳分析模型;并以疲劳分析结果作为锯架改进设计的基础,得出了改进后详细的锯架设计参数。结果表明:改进后,带锯条受力满足疲劳强度要求,很大程度上提高了锯条寿命及锯切精度。文中所建立的锯架力学模型适用广泛,具有较高的实际应用价值。
[Abstract]:According to the design of domestic band sawing machine, universal saw frame that the unreasonable design of short service life of the saw blade sawing, the accuracy and efficiency of non-compliance, the high cost of manufacturing, established the mechanical model of the saw frame of a band sawing machine; sawing machine as an example, according to the mechanical model of the blade of the saw frame stress cycle analysis, establish the blade fatigue analysis and fatigue analysis model; as a result of the saw frame based improved design, the improved design parameters with the saw frame. The results show that, after the improvement, the force of the saw strip meets the requirement of fatigue strength, and the saw blade life and the cutting precision are greatly improved. The mechanical model of sawing frame established in this paper is widely used and has high practical application value.
