Abstract

Die Erfindung betrifft eine Vorrichtung zur Erfassung eines Richtungswinkels, insbesondere eines Biegewinkels, eines in einer Vorschubrichtung transportierbaren Werkstücks, insbesondere eines Biegeteils (B), das in einer Biegemaschine (1) der Einwirkung eines in einer zur Vorschubrichtung unterschiedlichen Biegerichtung wirkenden Biegewerkzeugs (2) unterworfen wird.The invention relates to a device for detecting a direction angle, in particular a bending angle, one that can be transported in a feed direction Workpiece, in particular a bent part (B), which in a bending machine (1) the action of a bending direction that is different from the feed direction acting bending tool (2) is subjected.

Erfindungsgemäß ist vorgesehen, daß die Vorrichtung (1) mindestens eine Winkelmeßeinrichtung (10b) aufweist, die in Vorschubrichtung des Biegeteils (B) nach dem Biegewerkzeug (2) der Biegemaschine (1) angeordnet ist, daß die mindestens eine Winkelmeßeinrichtung (10b) einen Meßwertgeber (11) aufweist, der ein Meßelement (15) besitzt, das in eine Meßanlage an das Biegeteil (B) bringbar ist, daß zumindest die eine Winkelmeßeinrichtung (10b) um eine zur Biegeebene des Biegeteils (B) im wesentlichen orthogonalen Achse verschwenkbar ist, und daß ein von der oder den jeweils in Meßanlage an das Biegeteil (B) befindlichen Winkelmeßeinrichtungen (10a, 10b) erzeugten Meßsignale zu einer Steuer-/Auswerteeinrichtung der Biegemaschine (1) leitbar sind.

Figure 00000001
According to the invention, the device (1) has at least one angle measuring device (10b), which is arranged in the feed direction of the bending part (B) after the bending tool (2) of the bending machine (1), that the at least one angle measuring device (10b) has a measuring sensor (11) which has a measuring element (15) which can be brought into a measuring system on the bent part (B), that at least one angle measuring device (10b) can be pivoted about an axis which is essentially orthogonal to the bending plane of the bent part (B), and that a measuring signal generated by the angle measuring device (10a, 10b) located in the measuring system on the bending part (B) can be conducted to a control / evaluation device of the bending machine (1).
