Description

Verfahren zur Fertigung spanlos geformter Lagerbuchsen Die Erfindung betrifft ein Verfahren zur Fertigung spanlos geformter, insbesondere gerollter, Lagerbuchsen aus Band-und Streifenmaterial aus Verbund- oder Nassivlagerwerkstoff. Process for the production of non-cutting formed bearing bushes The invention relates to a process for the production of non-cutting shaped, in particular rolled, Bearing bushes made of tape and strip material made of composite or wet bearing material.

Bei der Verarbeitung von aus Band- und Streifenmaterial gestanzten oder geschnittenen Platinen zur Herstellung von spanlos geformten Lagerbuchsen müssen die Platinen an ihren Längsrändern auf einer Breite von 2 bis 6 mm spanend bearbeitet werden, um die beim Stanz- oder Schneidvorgang in diesem Bereich entstandenen Grate und Verbiegungen zu beseitigen.When processing punched from tape and strip material or cut blanks for the production of non-cutting bearing bushes machined the blanks on their longitudinal edges over a width of 2 to 6 mm to avoid the burrs created in this area during the punching or cutting process and eliminate bends.

Um ferner einen möglichst genauen Sitz der Lagerbuchsen im Lagergehäuse zu erreichen, ist es erforderiich, die umlaufenden Stirnflächen der spanlos geformten Lagerbuchsen spanend zu bearbeiten. Hinzukommt, daß es als konstruktive Maßnahme zur Abwendung von Kantenträgerbildung und zur besseren Montage erforderlich ist, die umlaufenden Kanten der Stirnflächen, vorzugsweise die Innenkanten der spanlos geformten Lagerbuchsen, mit spanend angebrachten Fasen zu versehen.In order to also ensure that the bearing bushes are seated as precisely as possible in the bearing housing To achieve this, it is necessary to remove the circumferential end faces of the non-cutting shaped Machining of bearing bushes. In addition, it is a constructive measure is necessary to avert the formation of edge beams and for better assembly, the circumferential edges of the end faces, preferably the inner edges of the non-cutting Shaped bearing bushes to be provided with machined bevels.

Alle diese Maßnahmen bedeuten aber nicht nur einen erhebt lichen Fertigungsaufwand, sondern sind auch zusätzlich noch mit einem nicht unbeträchtlichen Materialverlust verbunden.However, all of these measures not only mean considerable production costs, but are also with a not inconsiderable loss of material tied together.

Es ist deshalb die Aufgabe der vorliegenden Erfindung, eine Möglichkeit zu finden, um bei der Fertigung der spanlos geformten Buchsen sowohl eine verlustlose Herstellung der Ausgangsplatinen zu erreichen als auch eine spanende Bearbeitung der umlaufenden Stirnflächen sowie deren Kanten zu vermeiden.It is therefore the object of the present invention to provide a possibility to be found in the production of the non-cutting molded bushings both a lossless To achieve production of the starting blanks as well as machining the circumferential end faces and their edges.

Nach der Erfindung wird diese Aufgabe in der Weise gelöst, daß das Band- und Streifenmaterial an seinen Längsstirnflächen und -kanten spanlos verrundet oder angefast wird, wobei Je nach dem Verwendungszweck der daraus herzustellenden Lagerbuchsen der Radius der Verrundung 0,1 bis 0,5 mm, vorzugsweise 0,2 bis 0,3 mm oder die Anfasung 0,2 bis 1,0 mm x 10 bis 600, vorzugsweise 0,4 bis 0,8 mm x 20 bis 450, beträgt.According to the invention, this object is achieved in such a way that the Ribbon and strip material rounded without cutting on its longitudinal end faces and edges or is chamfered, depending on the intended use of the material to be produced from it Bearing bushes the radius of the rounding 0.1 to 0.5 mm, preferably 0.2 to 0.3 mm or the chamfer 0.2 to 1.0 mm x 10 to 600, preferably 0.4 to 0.8 mm x 20 to 450.

Zweckmäßigerweise werden die Längsstirnflächen und -kanten des Bandmaterials durch Walzen verrundet bzw. angefast.The longitudinal end faces and edges of the strip material are expediently rounded or chamfered by rolling.

Eine besondere Ausgestaltung des erfindungsgemäßen Verfahrens besteht darin, daß ein entsprechend breites Band in einem Verfahrensdurchlauf durch Walzprägen in mehrere Streifen zerteilt und diese Streifen gleichzeitig an ihren Längsstirnflächen und -kanten spanlos verrundet oder angefast werden.There is a special embodiment of the method according to the invention in that a correspondingly wide strip in one process run by roll embossing divided into several strips and these strips simultaneously on their longitudinal end faces and edges are rounded or chamfered without cutting.

Die nach dem erfindungsgemäßen Verfahren hergestellten Platinen und die daraus gefertigten Lagerbuchsen können ohne jede spanende Bearbeitung in Serie hergestellt und in Lagergehäuse eingebaut werden. Dadurch können die Bearbeitungsmaschinen für das Anbringen der Fasen an den Stirnflächen der Lagerbuchsen sowie die Maschinen fUr die Entfernung eines 2 bis 6 mm breiten Streifens an den Platinen entfallen.The circuit boards and manufactured by the method according to the invention the bearing bushes made from it can be used in series without any machining manufactured and installed in bearing housings. This allows the processing machines for making the chamfers on the end faces of the bearing bushes as well as the machines There is no need to remove a 2 to 6 mm wide strip from the circuit boards.

Das Verfahren nach der Erfindung ist sowohl für Massivals auch für Verbundlagerwerkstoffe bestens geeignet. PatentansprücheThe method according to the invention is for both massive and for Composite bearing materials are ideally suited. Claims
