精铸件内浇口的切割,过去都用气割、手敲等方法使铸件从直浇口棒上清除下来。但这些方法劳动强度高,生产效率低,有害尘埃多。为提高生产率,减轻劳动强度,我们试制成功了一台内浇口液压砂轮切割机。一、结构与工作原理: 本机结构见图。工件8的直浇口棒安放在支承架2和定位中心架7上。 Casting within the gate of the cutting, the past are using gas cutting, hand knocking and other methods to make castings from the sprue sticks removed. However, these methods have high labor intensity, low productivity and harmful dust. In order to improve productivity and reduce labor intensity, we successfully produced an ingot hydraulic wheel cutting machine. First, the structure and working principle: The structure of the map shown. The sprue bar of the workpiece 8 rests on the support frame 2 and the positioning center frame 7.
