某机压气机工作叶片采用TC4钛合金材料。叶片榫头上有2个高精度装配定位孔,孔小而深,加工难度大,是新机中需要解决的技术难关。我们经过反复探讨摸索,用旧的φ7手用铰刀,对铰刀的几何参数加以改进,并用一种简单的铰刀转接刀架,分别进行钻、镗、铰。解决了生产关键,提高了产品质最,生产效率提高了12倍。 1.工艺图的要求(见图1) 孔径φ6~(+0.008)光洁度▽8 孔深72毫米孔数2个位移度R0.01 垂直度φ0.01 叶片靠叶身型而定位,用低熔点合金固定
Some compressor working blades TC4 titanium alloy material. Blade tenon head has two high-precision assembly positioning hole, the hole is small and deep, difficult processing, the new machine needs to be solved technical difficulties. After repeated exploration and exploration, we improved the geometrical parameters of the reamer with the old φ7 hand reamer, and used a simple reamer to transfer the turret to drill, bore and ream respectively. Solve the production of the key to improve the quality of the most products, production efficiency increased 12 times. 1.
