    • A flange fitting for attaching to the lid (20) of a drum (21) includes a seal tube having a generally cylindrical main body with a relatively thin wall and an outwardly radiating frustoconical lip extension. Also included as part of the flange fitting is a standard drum plug flange having a generally cylindrical main body and an outwardly radiating, frustoconical lip. The drum plug flange is sized and shaped so as to fit within the seal tube such that the lip extension and the lip are generally coextensive with each other. These two components are then able to be anchored into the lid (20) of the drum (21) through a punch press operation which simultaneously clamps and crimps both the lip and lip extension into a raised boss recess thereby precluding any preassembly, such as by welding, of the seal tube and drum flange prior to assembly to the drum lid (20).
    • 用于附接到鼓的盖的凸缘配件包括密封管,该密封管具有大致圆柱形的主体,其具有相对较薄的壁和向外辐射的截头圆锥形唇缘延伸部。 还包括作为凸缘配件的一部分的标准鼓塞法兰具有大致圆柱形主体和向外辐射的截头圆锥形唇缘。 鼓塞法兰的尺寸和形状被设计成适合于密封管内,使得唇缘延伸部和唇缘彼此大致共同延伸。 这两个部件然后能够通过冲压操作被锚定在滚筒的盖中,该冲压操作同时将唇缘和唇缘延伸部分夹紧并卷曲到凸起的凸起凹部中,从而排除诸如通过焊接的任何预组装 和鼓法兰在组装到鼓盖之前。

    • Method of and apparatus for forming an opening (2) in a plate (1), the opening being defined by a tubular flange (3) projecting from the plate (1). The method comprises the steps of:
         forming a hole (20) in the plate (1), the hole (20) being of smaller diameter than the said opening (2);
         deforming the material of the plate (1), in a region immediately surrounding the hole, out of the plane of the plate (1);
         subsequently deforming the material of the plate (1) in the region surrounding the hole (20) into a frustoconical configuration of which the larger diameter is substantially equal to the intended diameter 1₃ of the tubular flange (3); and
         subsequently forming the frustoconical configuration into the said tubular flange (3).
    • 在板(1)中形成开口(2)的方法和设备,该开口由从板(1)突出的管状凸缘(3)限定。 该方法包括以下步骤:在板(1)中形成孔(20),孔(20)的直径小于所述开口(2); 使板(1)的材料在紧邻该孔的区域中从板(1)的平面变形; 随后将围绕孔(20)的区域中的板(1)的材料变形为截头圆锥形构造,其大直径基本上等于管状凸缘(3)的预期直径13; 并随后将截头圆锥形构造形成到所述管状凸缘(3)中。
