摘要： An integral cast-iron connecting rod blank having a smaller-diameter end, a shank, and a larger-diameter end with a crank opening is set on an inclined base, and the tip end of a laser beam applying device is positioned in the larger-diameter end. While a YAG laser beam from the laser beam applying device is being applied to diametrically opposite inner central wall regions of the larger-diameter end, the laser beam applying device is moved to form notches transversely in the respective inner central wall regions. Two spreading elements are placed in the crank opening, and then a tapered wedge is inserted downwardly between the spreading elements. A downward impact point load is applied to a load bearing surface of the wedge thereby to apply spreading forces to the larger-diameter end. A crack starting radially outwardly from the notches is developed in the larger-diameter end, dividing the larger-diameter end into a saddle and a cap. Mating surfaces of the saddle and the cap have interfitting surface irregularities which prevent the saddle and the cap from being combined in wrong orientations. Before the larger-diameter end is split open, the crank opening is finished for roundness while the larger-diameter end is being subjected to the same load as a fastening load by which the saddle and the cap will be fastened by bolts.
摘要翻译：具有小直径端部，柄部和具有曲柄开口的较大直径端部的一体铸铁连杆坯料设置在倾斜基座上，并且激光束施加装置的尖端位于较大的直径结束当来自激光束施加装置的YAG激光束被施加到大直径端的径向相对的内中心壁区域时，激光束施加装置被移动以在相应的内中心壁区域中横向形成凹口。两个扩展元件放置在曲柄开口中，然后锥形楔子向下插入在扩展元件之间。向下的冲击点载荷施加到楔形件的承载表面，从而将扩展力施加到较大直径端。在较大直径的端部处产生从凹口径向向外开口的裂纹，将较大直径端分成鞍座和盖。鞍座和盖子的配合表面具有互相配合的表面不规则性，防止鞍座和盖子以错误的方向组合。在大直径端部分开之前，曲柄开口完成圆形，而较大直径的端部承受与紧固负载相同的载荷，鞍座和盖子将通过螺栓紧固。

摘要： The tubular die of a centrifugal casting device of GNo.30 or above is employed suitably and powder is introduced while rotating, and an outer tubular body composed of that powder is provided. Subsequently, molten is introduced to the inner circumferential wall side of the outer tubular body while sustaining rotation of the tubular die thus forming an inner tubular body. The outer tubular body functions as a cooling metal (chiller) when the molten is cooled and solidified. In place of the outer tubular body composed of the powder, molten may be used for forming an outer tubular body or an outer tubular molding molded previously into tubular shape may be employed.
摘要翻译：使用GNo.30以上的离心铸造装置的管状模具，并且在旋转时引入粉末，并且设置由该粉末构成的外管体。随后，在保持管状模具的旋转的同时，将熔融物引入外管状体的内周壁侧，从而形成内管状体。当熔融物冷却和固化时，外部管状体用作冷却金属（冷却器）。代替由粉末组成的外部管状体，可以使用熔融形成外部管状体，或者可以采用先前成管状的外部管状成型体。

摘要： A cylinder liner has an outer circumferential surface around which another metal is to be cast. The cylinder liner also has a plurality of protrusions disposed on the outer circumferential surface and having respective substantially conical undercuts or necks which are progressively spread outwardly from the outer circumferential surface. The protrusions have respective flat faces on the distal ends of the undercuts.
