摘要： [Problem] The purpose of the present invention is to provide a form-rolling die and form-rolling method for a compound screw that use a cylindrical material to be threaded, enable the high-precision mass production of compound screws having a right-hand thread portion and a left-hand thread portion on the same region, do not cause rolling defects such as slips, and in which blockages do not occur even in the unlikely event of shavings being generated. [Solution] A form-rolling die structure is provided with die members which are pressed against a material to be threaded and which have rigid surfaces that are relatively displaced. The die members are equipped with a plurality of independent concave portions which form a substantially parallelogram shape when viewed from the normal of a virtual surface obtained by connecting the outermost portions of each of the rigid surfaces, and which are recessed from the virtual surface. Two of the corners at the sites corresponding to the four corners of the substantially parallelogram-shape of the concave portions are rounded. The periphery of each concave portion in the cross-section along the direction of the normal is rounded along the periphery of the substantially parallelogram shape. The concave portions form a substantially truncated-pyramid shape. The sites equivalent to the ridge lines of the concave portions are rounded in cross-sectional view perpendicular to the ridge line, and bases (35) are provided in the deepest sites (34).
摘要翻译：发明内容本发明的目的在于提供一种用于使用圆柱形材料进行螺纹化的复合螺杆的成型轧制模具和成形方法，能够高精度批量生产具有右侧的复合螺杆螺纹部分和左螺纹部分不会引起滚动缺陷，例如滑动，即使在不太可能发生的刨屑的情况下也不会发生堵塞。 [解决方案]一种成型模具结构设置有模具构件，该模具构件被压靠在要被螺纹的材料上并且具有相对位移的刚性表面。模具构件配备有多个独立的凹部，当从通过连接每个刚性表面的最外部分并且从虚拟表面凹陷而获得的虚拟表面的法线观察时，形成基本上平行四边形。对应于凹部的大致平行四边形形状的四个角部的位置处的两个角部是圆形的。沿着法线方向的横截面中的每个凹部的周边沿着大致平行四边形的周边圆化。凹部形成大致截头棱锥形状。与凹部的脊线相当的部位在与脊线垂直的剖视图中为圆形，基部（35）设置在最深部位（34）。

摘要： [Problem] The present invention aims to provide, without an increase in cost, a directional indication structure for threaded bodies that enables the visual and tactile distinction between left-hand thread and right-hand thread threaded bodies, enables the identification, from the external appearance and the external surface, of which direction a threaded body should be rotated in order to be tightened or loosened, enables mass production and the like, has a good external appearance, and has form properties that do not impinge the properties inherent in the threaded body or the strength, etc. thereof.[Solution] Directional indicators are asymmetrically provided, in association with the direction of rotation of the threads, to the outer surface of a solid body constituting a threaded body, said directional indicators having corner portions which indicate the forward direction in the direction of rotation, and corner portions which indicate the direction in which the threaded body will advance when rotated in the forward direction in the direction of rotation.
