Abstract

The compact notching device permits dimensionally accurate notching with relatively low driving forces and a high output volume. Cam-controlled movement of the outer ring of the notching apparatus allows the depth profile of notches on the connecting element to be controlled.

Description

Beschreibungdescription

Die Erfindung betrifft eine Vorrichtung zum Kerben von Verbindungselementen. Sie ist in ihrem Wirkprinzip zeichnerisch dargestellt.The invention relates to a device for notching of fasteners. It is in its working principle shown graphically.

Die in dem rotatorisch bewegtem Vorrichtungs-Außen­ ring 2 eingesetzten Kniehebelpfannen 3 betäti­ gen bei Drehung des Teiles 2 um den Grundkörper 1 eine Umlenkung der Kniehebel 4 und damit weiterhin die zentrische Bewegung der Werkzeugträger- Schieber 5, die in den Ausnehmungen des fest­ stehenden Grundkörpers 1 geführt sind. Als Werkzeuge 7 kommen Prägekeile oder Prägeräder in Frage. Die Feineinstellung der Schieber 5 erfolgt über Stellschrauben 6.The toggle lever cups 3 used in the rotationally moved device outer ring 2 actuate when the part 2 is rotated around the base body 1, deflecting the toggle lever 4 and thus continue the central movement of the tool carrier slide 5 , which is in the recesses of the fixed base body 1 are led. Embossing wedges or embossing wheels can be used as tools 7 . The fine adjustment of the slide 5 is carried out using set screws 6 .

Angaben zur GattungInformation on the genus

Die Bewegung über Kniehebel ergibt eine kinematisch und kräftemäßig günstige Bewegung bezüglich des Kerbvorganges. Durch den Einbau der Kniehebelpfannen in den drehend bewegten Außenring wird an mehreren Stellen des Verbindungselementes gleichzeitig eine Kerbung erreicht. The movement via the toggle lever results in a kinematic and vigorously favorable movement regarding the Notching process. By installing the toggle cups in the rotating outer ring is on several Set the connecting element at the same time Notch reached.  

Stand der TechnikState of the art

Bei bisher üblichen Kerbvorrichtungen wurden die Kerbwerkzeuge-Schieber über Keile angetrieben an Stelle der Kniehebelpfannen und Kniehebel.In the case of notch devices customary up to now, the Notch tool slider driven by wedges Place the toggle cups and toggle levers.

Kritik des Standes der TechnikCritique of the state of the art

Die Bewegungsführung ist dabei ungünstiger und die erforderlichen Antriebsmomente sind infolge größerer Reibungskräfte höher.The movement control is less favorable and the required drive torques are due to larger Frictional forces higher.
