关于法兰背面超长锪窝加工方法的研究

Study on the processing method of the super long armpit on the back of the flange

法兰背面铸窝由于铸造错型,导致铸窝相对于铸件设计图纸错偏,一侧多料干涉螺栓的安装使用。介绍一种利用机加工的方法去除铸件铸窝多料的方法,返修效果较好,不需要占用机床资源,可在铸件类似结构部位返修中推广应用。

Due to the mis-casting of the casting armpit on the back of the flange,the casting armpit is misaligned with respect to the casting design drawings.A method of removing excessive materials from casting armpit by machining has been introduced in the text.The repair effect is better without needing to occupy the machine tool resources,which can be applied in the repair of similar structural parts of castings.
