我厂某产品由若干段首尾相接的曲面孔组成,每段均长980mm,其中最大一段的大端孔径为φ1200mm,重3.5t,工件材料为QT42-10。要求各段相接处接差≤0.05mm,各段曲面孔母线由座标给出,孔轮廓误差≤±0.05mm,光洁度6以上。为此,我们在C5225立式车床上安装了自行设计制造的立车液压仿形刀架,并采取了一系列有效的工艺措施,使工件达到设计要求。一、立车液压仿形刀架 1.工作原理通常的卧式液压仿形车床都采用靠模样板固定在床身上,即处于静止状态;随动阀与刀架的拖板连接,同作仿形运动。而我们设计的液压仿形刀架却采取了
I plant a product by a number of segments connected to the curved surface of the hole, each length 980mm, of which the largest section of the large end of the aperture φ1200mm, weight 3.5t, the workpiece material is QT42-10. Requirements of the various phase connection at the poor ≤ 0.05mm, each section of the surface busbar given by coordinates, hole contour error ≤ ± 0.05mm, finish 6 or more. To this end, we have installed in the C5225 vertical lathe Li self-designed hydraulic profiling turret, and adopted a series of effective measures to make the workpiece to meet the design requirements. First, the vertical hydraulic carving profile turret 1. Working principle The usual horizontal hydraulic profiling lathe are used by the model fixed on the bed, that is in a quiescent state; follow the valve and the knife carriage connection, with the imitation Shape movement. The hydraulic profiler we designed was taken
