Abstract

Die Erfindung betrifft eine Vorrichtung (2) zum Umlegen einer Bördelkante (16) eines Werkstücks (15) durch Rollfalzen mit einer Werkzeugeinheit (1), die mittels eines Antriebs gesteuert bewegbar ist. Ferner ist eine Halteeinrichtung (14) zur Halterung des Werkstücks (15) und zur Unterstützung eines Bereichs der Bördelkante (16) vorgesehen. An der Werkzeugeinheit (1) ist eine drehbar gelagerte Falzrolle (5, 6, 7) vorgesehen, die unter Druckaufbringung und bestimmter Winkelstellung entlang und in Anlage an der Bördelkante (16) zu deren Umlegung rollbar ist. Erfindungsgemäß ist die Werkzeugeinheit (1) am Antrieb an einer Schwenkachse (4) schwenkbar gelagert und um einen bestimmten Schwenkwinkel in wenigstens zwei Arbeitspositionen schwenkbar. Den wenigstens zwei Arbeitspositionen ist jeweils eine an der Werkzeugeinheit (1) drehbar gelagerte Falzrolle (5, 6, 7) zugeordnet. Die wenigstens zwei Falzrollen (5, 6, 7) weisen unterschiedlich ausgebildete und bezüglich der Bördelkantenumlegung unterschiedlich wirksame Falzrollenumfangsflächen (11, 12, 13) auf, wobei für eine wenigstens zweistufige Umlegung die Werkzeugeinheit (1) in der ersten Arbeitsposition mit der ersten Falzrolle (5) in deren Funktionsstellung und anschließend die Werkzeugeinheit (1) in der zweiten Arbeitsposition mit der zweiten Falzrolle (6) in deren Funktionsstellung entlang der Bördelkante (16) bewegbar ist.

Figure 00000001
The invention relates to a device (2) for transferring a flanged edge (16) of a workpiece (15) by roll-folding with a tool unit (1) which is controlled by a drive movable. Furthermore, a holding device (14) for holding the workpiece (15) and for supporting a portion of the flanged edge (16) is provided. On the tool unit (1) a rotatably mounted folding roller (5, 6, 7) is provided, which is rollable under pressure application and certain angular position along and in abutment against the flanged edge (16) for their assignment. According to the invention, the tool unit (1) is pivotally mounted on the drive on a pivot axis (4) and pivotable about a specific pivot angle in at least two working positions. The at least two working positions are each associated with a folding roller (5, 6, 7) rotatably mounted on the tool unit (1). The at least two folding rollers (5, 6, 7) have differently formed and with respect to the Bördelkantenumlegung different effective Falzrollenumfangsflächen (11, 12, 13), wherein for at least two-stage assignment, the tool unit (1) in the first working position with the first folding roller ( 5) in its functional position and then the tool unit (1) in the second working position with the second folding roller (6) in its functional position along the flanged edge (16) is movable.
