摘要

采用有限元法建立了四种典型体结构圆锯片的辊张紧过程。对轧辊张紧后的4种叶片进行了弹塑性变形模拟试验，分析了轧辊减径位移对平整度的影响。比较了轧辊张紧后叶片承受切削温度负荷的能力。理论结果表明，在适当的张紧状态下，四种具有独特本体结构的圆锯片各具有不同的工艺参数。不同本体结构的圆锯片经过适当的张紧处理后，其承受切削温度负荷的能力有所提高。

DEFORMATION BEHAVIOR OF CIRCULAR SAW BLADES WITH DIFFERENT BODY STRUCTURES AFTER ROLL TENSIONING

A roll tensioning process for circular saw blades with four typical body structures was built with the finite element method. After roll tensioning, the elastoplastic deformation behaviors of the four blades were simulated and tested and the effects of roll reduction displacement on flatness were analyzed. The abilities of the blades to withstand cutting temperature load after the roll tensioning process were compared. The theoretical results showed that each of the four circular saw blades with unique body structures had different process parameters in an appropriate tensioning state. Circular saw blades with different body structures showed variation in improvements of their ability to withstand cutting temperature load after an appropriate tensioning process.
