Abstract

Die Abkantmaschine dient zum Biegen von Blechen, auch in Kombination mit Einheiten zum Abscheren, Ausklinken, Profilieren von Blechen und Platten und weist mindestens drei zur Aufnahme von Biegewerkzeugen dienende Wangen, nämlich eine Ober-, eine Unter- und eine Biegewange auf. Die Werkzeuge bestehen aus einer Vielzahl von einen Werkzeugelementesatz bildende, nebeneinander längs der jeweiligen Wangen angeordneten Werkzeugelementen. Jeder von diesen weist einen Werkzeugsteckbolzen auf und jede Wange eine in deren Längsrichtung fluchtende Vielzahl von zueinander parallelen und voneinander gleich beabstandeten Passbohrungen für die Werkzeugsteckbolzen. In diese Passbohrungen sind die Werkzeugsteckbolzen so einsetzbar, daß sie in der eingesetzten Lage lösbar arretiert und unverdrehbar in zur Längsrichtung der Wangen fluchtenden Lage gehalten sind. The folding machine is used for bending sheet metal, also in Combination with units for shearing, notching, profiling Sheets and plates and has at least three for receiving Bending tool cheeks, namely an upper, a lower and a bending beam. The tools consist of a variety of one Tool element set forming, side by side along the respective cheeks arranged tool elements. Each of these has one Tool pins on and each cheek in the longitudinal direction aligned multitude of parallel and equal to each other spaced fitting holes for the tool pins. In these The tool plug pins can be inserted into that it is releasably locked in the inserted position and non-rotatable in are aligned with the longitudinal direction of the cheeks.
