新型双功能开铁口机钻冲机构

A New Type Drill Carriage of the Taphole Drill

建立了新型开铁口机电动钻冲机构的力学模型,计算了它的固有频率和主振型。对钻冲机构的钻进速度进行了实测分析研究,获得了机构的送进力、被钻材料的硬度、钻头形式和有无冲打对钻进速度的影响关系。

Mechanical model of the drill carriage with rotation and vibrating hammer for the new type taphole drill is established. The natural frequencies and mode shapes of the model are calculated. The main parameter-push force, hardness of the material drilled, bit shapes and whether or not vibrating hammer, which affect the drilling speed and the relationship among the parameters are studied on the basis of experiment.
