摘要： A spiral tap is disclosed having a thread portion having an external thread, spiral flutes which is fluted in the same direction as a cutting/rotating direction, as seen in a direction away from a shank side, to divide the external thread, and cutting edges formed along the spiral flutes; the thread portion including a full thread portion having a fixed outer diameter, and a chamfer portion decreasing in outer diameter toward a tap end; the chamfer portion being screwed into a prepared hole to cut an internal thread on an inner circumferential wall of the prepared hole and to discharge chips along the spiral flutes toward the shank; the chamfer portion having an external thread with screw threads which is formed such that outer circumferential portions are removed, at a linear line for cutting as seen from a direction perpendicular to a cross-section involving an axis O, from the screw threads having the same dimension as that of the full thread portion; and the linear line intersecting the axis O at an inclined angle θ falling in a range of −15°≦θ≦30′ with a side decreasing in diameter toward the tap end being defined positive.

摘要： A cold forming tap and a method of manufacturing the cold forming tap. Since the following side margin M2 of the following side flank (22b) of a male screw (22) is deviated from the leading side margin M1 of the leading side flank (22a) thereof in a screw-in rotating direction as shown in FIG. 2 (a), the following side margin M2 bites precedently in biting and a force to push back a tap is suppressed to reduce a tapping torque. Also, a margin part M may be formed parallel with the axis of the cold forming tap (10), it can be easily manufactured at low cost Namely, when the male screw (22) is ground by a grinding wheel (32), a margin can be symmetrically formed with respect to a bottom as shown in FIG. 2 (b) when the tilt angle θ of the axis of a tap material (30) relative to the centerline of the grinding wheel (32) is the same as the lead angle of the male screw. However, when the tilt angle θ is increased more than the lead angle, the following side margin M2 can be deviated in the screw-in rotating direction ac shown in FIG. 2 (a). As a result, the cold forming tap can be easily manufactured at (b) low cost in the same manner as before.

摘要： A following margin of a following flank of an external thread is shifted more in a screw-rotation direction than a leading margin of a leading flank. Thus, during biting, the following margin bites first, thereby suppressing a force that pushes back a tap and reducing a tapping torque. Because margin portions can be disposed parallel to an axis of a thread forming tap, working is easy and manufacture can be performed inexpensively. When, in forming an external thread by grinding by a grinding abrasive, an inclination angle of the axis of a tap blank and an abrasive axis of the grinding abrasive is equal to a lead angle of the external thread, the margins are formed symmetrically across a root. On the other hand, if the inclination angle is made greater than the lead angle, the following margin can be shifted in the screw-rotation direction, enabling manufacture to be performed as easily and inexpensively as in a conventional case.
摘要翻译： 外螺纹的后端的跟随余量在螺旋旋转方向上比前导侧面的前缘更多地偏移。 因此，在咬入时，以下边缘首先咬伤，从而抑制推回龙头的力并减小攻丝扭矩。 因为边缘部分可以平行于螺纹成型丝锥的轴线布置，所以加工容易，并且可以廉价地进行制造。 当通过研磨研磨剂研磨形成外螺纹时，丝锥坯料的轴线和研磨研磨剂的研磨轴线的倾斜角度等于外螺纹的导程角，边缘对称地形成 根。 另一方面，如果倾斜角度大于导向角，则能够使螺纹旋转方向上的下一个边缘移动，从而能够像以往那样容易且廉价地进行制造。
