    摘要： A fastening screw having an elongate shank (1), and a drilling tip (2) and a head (3) provided at respective opposite ends of the shank (1). The drilling tip (2) has a cutting edge (5) for cutting through metal and a flute (6) extending longitudinally of the shank (1). A thread (8) is formed on the shank (1) and extends over a portion of the section of the shank (1) in which the flute (6) is formed. A method of forming a fastening screw from a screw preform (9), includes deforming the preform (9) to create a drilling tip (2) which has at least one cutting edge (5) and a flute (6), and applying a thread (8) to the shank (1) in the region in which the flute (6) is formed.

    摘要： A method and apparatus (12) for cold sizing a round workpiece (14) having round surfaces of cylindrical shapes that are coaxial about a central axis A of the workpiece and have different diameters. A support (54,55) rotatably mounts the workpiece (14) about its central axis A between a pair of die assemblies (24a, 24b) which are spaced from each other. Each die assembly (24a,24b) includes a plurality of dies (56,58,60,62) that are respectively aligned with the round surfaces (46,48,50,52) of the workpiece (14). Movement of the die assemblies in opposite directions as each other engages sizing surfaces (66,68,70,72) of the dies with the aligned round surfaces of the workpiece to pressure size the workpiece surfaces. In one embodiment of the sizing apparatus (12), the dies assemblies (24a, 24b) have elongated shapes and are moved rectilinearly in a parallel relationship to each other to perform the sizing. Another rotary embodiment of the sizing apparatus (12ʹ) includes rotary die assemblies (24aʹ,24bʹ) mounted by associated spindles (85) whose rotation likewise pressure sizes the round workpiece surfaces. Both embodiments of the sizing apparatus are disclosed as including forming projections for forming projections for forming projections such as splines (82) and/or a helical thread (84) on the sized surfaces of the workpiece.

A support (54, 55) rotatably mounts the workpiece (14) about its central axis A between a pair of die assemblies (24a, 24b) which are spaced from each other. Each die assembly (24a, 24b) includes a plurality of dies (56, 58, 60, 62) that are respectively aligned with the round surface (46, 48, 50, 52) of the workpiece (14). Movement of the die assemblies in opposite directions as each other engages sizing surfaces (66, 68, 70, 72) of the dies with the aligned round surfaces of the workpiece to pressure size the workpiece surfaces. In one embodiment of the sizing apparatus (12), the dies assemblies (24a, 24b) have elongated shapes and are moved rectilinearly in a parallel relationship to each other to perform the sizing. Another rotary embodiment of the sizing apparatus (12') includes rotary die assemblies (24a', 24b') mounted by associated spindles (85) whose rotation likewise pressure sizes the round workpiece surfaces. Both embodiments of the sizing apparatus are disclosed as including forming projections for forming projections for forming projections such as splines (82) and/or helical thread (84) on the sized surfaces of the workpiece.

    摘要翻译： 一种用于对具有圆形形状的圆形表面的圆形工件（14）进行冷定径的方法和装置（12），所述圆形工件具有与工件的中心轴线A同轴且具有不同直径的圆柱形形状。 支撑件（54,55）将工件（14）围绕其中心轴线A可旋转地安装在彼此间隔开的一对模具组件（24a，24b）之间。 每个模具组件（24a，24b）包括分别与工件（14）的圆形表面（46,48,50,52）对准的多个模具（56,58,60,62）。 模具组件在相反方向上的运动，彼此相互啮合具有对准的工件的圆形表面的模具的尺寸表面（66,68,70,72）以对工件表面进行压力大小。 在尺寸设备（12）的一个实施例中，模具组件（24a，24b）具有细长形状并且彼此平行地直线移动以执行尺寸调整。 尺寸设备（12分钟）的另一个旋转实施例包括由相关主轴（85）安装的旋转模具组件（24a min，24b），其旋转同样地压缩圆形工件表面的尺寸。 尺寸调节装置的两个实施例被公开为包括用于形成用于在工件的尺寸表面上形成诸如花键（82）和/或螺旋螺纹（84）的突起的突起的形成突起。
