无卡轴旋切机变速进给模型与恒线速旋切运动轨迹模型的研究

Study on the Model both Cutting Variable-speed of the Log-core Veneer Lathe and Moving Locus Model with Constant-speed Peeling

详细分析了无卡轴旋切机的工作原理,推导了旋切过程中刀刃进给速度与圆木直径的数学模型,同时得出旋切时间的近似计算式。从中可知,旋切过程中刀刃进给速度必须按一定规律变化才能保证旋切机正常工作。建立了旋切机恒线速旋切的运动轨迹模型,推导出旋切机恒线速旋切时间的精确计算式,并在此基础上提出了旋切时间简便的近似计算式。这些研究结果均可用于指导设计和进行实际生产。

Working principle of log-core veneer lathe had been analyzed in detail .and the mathematical model between the knife-carriage feeding speed and the diameter of the log core was established .in the meantime, the approximation cutting time formula was also derived .The feeding speed must be changed with continuousness and a rule .which can let the lathe work well .Moving locus model of invariable-speed peeling was also founded .precision calculating formula of invariable-speed peeling was deduced.In the same time.the simplification cutting-speed formula was also derived. These results of the research will provide a guide for the designing and the producing practice.
