Gewindeschneidwerkzeug. Patentiert im Deutschen Reiche vom 31. März 1925 ab.Thread cutting tool. Patented in the German Empire on March 31, 1925.
Die vorliegende Erfindung 'betrifft ein Gewindeschneidwerkzeug mit Flankensehnitt. Das Neue besteht darin, daß von den aufeinanderfolgenden Zahnlücken abwechselnd die eine von der Mitte aus nach beiden Seiten hin verbreitert, die andere im Grunde vertieft ist.The present invention relates to a thread cutting tool with flank cut. That New consists in the fact that one of the successive tooth gaps alternates widened from the middle to both sides, the other is basically deepened.
Das hat den Vorteil, daß sich flache Späne bilden, welche leicht abfließen und sich leicht abheben lassen, ohne daß, wie beim Schneiden voller Gewindeschneidzähne, die Gewindegänge leicht ausreißen.This has the advantage that flat chips are formed, which flow off easily and easily lift off without the thread turns, as is the case with cutting full thread cutting teeth tear out easily.
Die Zeichnung veranschaulicht als Ausfuhrungsbeispiel einen Gewindebohrer. Es zeigen:The drawing illustrates a tap as an exemplary embodiment. Show it:
Abb. ι einen Querschnitt durch den Bohrer, Abb. 2 drei Gewindezahnreihen des Bohrers.Fig. Ι a cross section through the drill, Fig. 2 three rows of thread teeth of the drill.
Die Schneidzahnlücken 2, 4, 6, 8 sind verbreitert, die Schneidzahnlücken i, 3, 5,7, 9 sind im Grunde vertieft. Die verbreiterten Zahnlücken, schneiden nur im Grunde und bilden den Kopf des Gewindes am Arbeitsstück, die vertieften Zahnlücken schneiden nur mit den Flanken.The cutting tooth gaps 2, 4, 6, 8 are widened, the cutting tooth gaps i, 3, 5, 7, 9 are basically deepened. The widened tooth gaps, just basically cut and form the head of the thread on the workpiece, the recessed tooth gaps only cut with the Flanks.
