Description
Zylindrisches Kordelrädchen mit gebrochenen Kanten Der Zweck der Erfindung ist die Vermeidung der-bei der Herstellung geriefter Griffflächen mittels auf Drehbänken und Drehautomaten verwendeter Kordelrädchen als nachteilig empfundenen überaus großen Beanspruchung und der dadurch bedingten höchsten Anforderungen an die Lebensdauer der benutzten Werkzeugmaschinen, die durch das beim Anlassen der Maschinen hervorgerufene Anspringen und gratbildende Eingraben der bisher bekannten Kordelrädchen mit stumpfer Angriffsfläche erzeugt werden, wodurch neben der Bildung eines zu starken Axialdruckes auch durch das grathildende Eingraben oft mangelhafte Arbeit geleistet wurde.Cylindrical cord wheel with broken edges The purpose of the invention is the avoidance of the gripping surfaces grooved in the production by means of lathes and automatic lathes used cord wheels perceived as disadvantageous extremely large Stress and the resulting highest demands on the service life of the machine tools used, those caused by the start-up of the machines Jumping off and burr-forming digging of the previously known cord wheels with blunt ones Attack surface are generated, which in addition to the formation of an excessive axial pressure even the burr-forming digging has often done poor work.
Die Erfindung besteht darin, daß bei einem mit gebrochenen Kanten versehenen Kordelrädchen auch die durch die Kantenbrechung entstandenen Flächen eine Kordelung aufweisen.The invention consists in that at one with broken edges equipped with cord wheels, the surfaces created by the breaking of the edges have a cord.
Die beiderseitig angearbeiteten scharfen Anschnittkanten arbeiten die Form vor und erleichtern dadurch die Hauptarbeit. Wenn diese scharfen Anschnittkanten das Arbeitsstück berühren, entstehen sofort an der scharfen Werkstückskante bei ganz leichtem Anpressungsdruck die Greifstellen dieser scharfen Zähne; das Rutschen und Gleiten wie bisher fällt weg.Work on the sharp bevel edges that have been worked on on both sides the shape and thereby facilitate the main work. If these sharp bleed edges touching the workpiece will immediately appear on the sharp workpiece edge the gripping points of these sharp teeth with very light pressure; the sliding and sliding as before is no longer necessary.
Da diese scharfen Anschnittkanten schräg liegen, entwickelt sich ein sanftes Formdrücken; selbstverständlich kommt zu Anfang der Arbeit Grat zum Vorschein, der aber durch die günstig liegende Anschnittsform in die erzeugten Zähne mit hin8ingepreßt wird, wodurch die entstehende Kordelung ein sauberes und gleichmäßiges Aussehen erhält.Since these sharp cut edges are sloping, a gentle compression molding; of course, a ridge appears at the beginning of the work, which, however, is pressed into the generated teeth due to the favorable chamfer shape which gives the resulting cord a clean and even appearance receives.
