摘　　要：煤机滚筒上的螺旋叶片成形主要包括下料、压制和焊接等过程。其中下料是最重要的环节之一,通过对多种下料方法的比较,决定采用三角形法。将三角形法的设计过程引入Auto-CAD,利用其二次开发功能,在Visual LISP的集成环境下利用Auto LISP语言编辑下料图的设计程序,从而实现参数化绘图,大大提高了设计的效率和质量。在叶片的压制过程中,回弹现象是必然的,只能减少,不能避免。回弹现象的产生与材料的机械性能、组织状态及弯曲方式等因素有关。对于回弹量的估算和回弹的控制是影响叶片加工质量的重要因素。Helical vane of shearer drum, the form mainly include cutting, press, welding and so on. Cutting is the important segment in these processes. Many cutting methods are compared, the triangle method is applied at last. The combination of the design processing of the triangle method and AutoCAD, which has the second development function and the integrated circumstance - Visual LISP, makes the efficiency and quality of design more perfect. The swelling can＇t be avoided in the press process, only be reduced. Swelling relates to mechanical property, structural state, bending mode and so on. The estimation and controlling are the important factors of quality of the vane.
