摘要
采矿凿岩机的气腿以前用钢管制造，改用铝合金管材制造将对凿岩机带来轻量化的效果。通过优化合金成分，改进拉伸工具，完善生产工艺，最终生产出了满足凿岩机使用要求的风动工具铝合金管材。
The material of pneumatic tool tubes on mining rock drill has changqd from steel toaluminium alloy. That is great improvement on mining rock drill reducing weight. The products accord withthe use requirement have been produced by optimizing alloy chemical composition, improving drawing tools,consummating production process.
