Description

Walzrolle zum Rollen von Profilen, insbesondere Gewinde.Rolling roller for rolling profiles, especially threads.

Beim Rollen von Gewinden und anderen Profilen mittels Walzrollen, die das Profil in Form von konzentrischen Rillen oderein-oder mehrgängigen Wendeln aufweisen, hat man bereits vorgeschlagen, die Profile an einem oder beiden den der Rolle verschieden hoch vorzusehen, um dadurch zu erreichen, dass die gewünschte Profiltiefe erst nach Durchlauf dieser ersten Einlaufprofile erreicht wird. Man verfuhr dabei so, dass man die Profilkämme der Fertigprofile mit oder ohne den Profilgrund dem Einlaufwinkel entsprechend absetzt und das nach dem Absetzen verbleibende Restrofil an seinen Spitzen abrundete.When rolling threads and other profiles by means of rolling rollers, which the profile in the form of concentric grooves or have single or multi-start coils, one already has proposed to provide the profiles of different heights on one or both of the roller in order to achieve that the desired profile depth is only achieved after these first inlet profiles have passed through. The procedure was that the profile crests of the finished profiles, with or without the profile base, were deposited according to the inlet angle and the tips of the residual profile remaining after the deposition were rounded off.

Diese Rollen reichen für das Rollen von Gewinde- und anderen Profilen mit Flankenwinkel von etwa 550 bis 600 aus, sind aber für die Formgebung schwieriger Profile nicht genügend. Wenn es sich beispielsweise darum handelt, Profile mit sehr starken Steigungen oder flache Walzprofile zu rollen, bei deren Erstellung bekanntlich die Oberfläche des Werkstückes zum Abblättern neigt, oder wenn sehr schwache bzw. spitze Profile gerollt werden sollen, bei denen erhöhte Bruchgefahz bestehtl, dann kommt man nicht damit aus, die Einlaufprofile lediglich an ihren Spitzen abzurunden. Man muss vielmehr nach der Neuerung beim Ein@auf ganz andere Profile vorsehen, die sich von den Fertigprofilen nicht nur hinsichtlich der Höhe, sondern vielmehr grundsätzlich unterscheiden. These roles are sufficient for rolling thread and other profiles with a flank angle of around 550 to 600, but are more difficult to shape Insufficient profiles. For example, when it comes to profiles with very to roll steep gradients or flat rolled profiles, as is well known when creating them the surface of the workpiece tends to peel off, or if very weak or pointed profiles with an increased risk of fracture are to be rolled, then it is not possible to just round off the inlet profiles at their tips. Rather, after the innovation at Ein @, you have to go to completely different profiles provide, which differ from the prefabricated profiles not only in terms of height, but rather differ fundamentally.

Während man also-bei den bekannten Rollen lediglich die Kämme des Fertigprofils absetzte, hat man nach der Neuerung Vorprofile stu entwickeln, bei denen der Schraubenverlauf die Form eines leicht rollbaren Profils aufweist und durch « eeignete Übergangstora in die jeweils gewünschte Fertigform allmählich übergeht, Auf der Zeichnung sind und zwei verschiedene Einlauf profile 1 und 2 einer Rolle zum Rollen von Schwellenschrauben gezeigt, die sich untereinander und vom Ferigprofil 3 grundsätzlich unterscheiden, indem sowohl dieProfilhohen hl und h2 als auch die Breiten b1 und b2 sowie die Flankenwinkel W1 und W2 voneinander abweichen. Selbstverstündlich muss sich die Form dieser Vorprofils nach dem gewollten Fertigprofil richten. : Es sei ausdrücklich erwähnt, dass sich die Neuerung sowohl auf Rollen mit parallel zueinander verlaufenden kreisförmigen Profilrillen als auch auf solche Rollen bezieht, bei denen das Profil in Form einer ein-oder mehrgängigen Wendel bzw. Schraubenlinie auf dem Rollenumfang vorgesehen ist, wobei sich im Übergang der unterschiedlichen Profile ein Misohprofil ergibt, welches ebenso wie die Vorprofile je nach der Form des Fertigprofile die verschiedensten Formen aufweisen kann. While you only have the combs with the known roles of the finished profile settled, one has after the innovation preliminary profiles stu develop in which the screw course has the form of an easily rollable profile and gradually merges into the desired finished form through a suitable transition torch differ from the finished profile 3 in that both the profile heights hl and h2 and the widths b1 and b2 as well as the flank angles W1 and W2 differ from one another. It goes without saying that the shape of this preliminary profile must be based on the desired finished profile. : It should be expressly mentioned that the innovation relates both to rollers with circular profile grooves running parallel to one another and to those rollers in which the profile is provided in the form of a single or multiple helix or helical line on the roller circumference The transition of the different profiles results in a Misoh profile, which, like the preliminary profiles, depends on the Shape of the finished profile can have a wide variety of shapes.
