用于制造自攻螺纹的螺钉的方法
摘要：
本发明涉及一种用于制造自攻螺纹的螺钉(11)的方法，所述螺钉具有杆部(12)和一个与杆部(12)一体地构成的并局部沿圆周设置在杆部上的螺纹(13)。在杆部(12)上构成螺纹(13)之后，接着将多个空隙(21)压入到螺纹(13)中。然后将多个紧凑的切割体(22)焊入到螺纹(13)中的空隙(21)中，在此切割体(22)由硬质材料制成并且硬度大于螺纹(13)的硬度。本发明还涉及一种用于执行该方法的压制装置。
摘要（英）：

The invention relates to a method for producing a thread moulding screw (11), the screw has a rod (12) and a thread (13) integrated with the rod (12) and partially arranged on the rod along the circumference. after the thread (13) is formed on the rod (12), a plurality of gaps (21) are pressed-in the thread (13). Then a plurality of compact cutting bodies (22) are welded into the gaps (21) of the thread (13), therein, the cutting bodies (22) are made of hard materials and have the hardness greater than the hardness of the thread (13). The invention also relates to a compacting device for the method.
