火焰数控切管机割炬轨迹研究及仿真

STUDY AND SIMULATION OF TORCH TRACK FOR THE FLAME NC PIPE CUTTING MACHINE

在火焰数控切管机割炬运动分析的基础上,定义了表达割炬轨迹所需的参考面和相关参数,建立了带坡口角的管-管相贯、管-板相贯相贯线数学模型,提出了最大z坐标原则求K形接头相贯线的方法。对管-管相贯、K形接头相贯的切割实例进行了仿真分析,研究了割炬轨迹和相关参数的关系。

Based on the analysis of the torch movement for the flame numerical controlled pipe cutting machine, reference planes and related parameters are defined for the expression of the torch track, intersecting curve models with groove angle of the pipe-pipe and pipe-plate are also built. And the principle of z-max is proposed for the intersecting curve of the K type. The real cutting examples about intersection of pipe-pipe and K type are simulated and analyzed, and the relationship between torch track and related parameters is studied.
