Abstract

Um beim Abkanten von Blechen auch Bleche (13) abkanten zu können, bei denen die Formbacke nicht gleichmäßig an der Biegelinie angreifen kann, wird erfindungsgemäß vorgeschlagen, die Formbacke (4.1) in einem Gehäuse verschwenkbar zu führen und zwar derart, dass eine Abkantung um die Biegelinie möglich ist. Dies wird dadurch erreicht, dass die Formbacke (4.1) in einer Führung in einem Gehäuse (5) geführt ist und von einem über Hydraulikzylinder betätigbaren Schlitten über eine Rolle und eine an der Formbacke (4.1) befestigten Hebel (6) verschwenkt wird.

Figure 00000001
In order to be able to bend metal sheets (13) when the shaped jaw cannot grip the bending line evenly when bending sheets, it is proposed according to the invention to guide the shaped jaw (4.1) in a housing so that it can be bent so that the edge is bent Bending line is possible. This is achieved in that the mold jaw (4.1) is guided in a guide in a housing (5) and is pivoted by a slide which can be actuated by means of a hydraulic cylinder, via a roller and a lever (6) fastened to the mold jaw (4.1).
