Abstract

Eine Biegemaschine zum mehrseitigen Biegen, insbesondere Schwenkbiegen, von plattenförmigen Werkstücken (1) oder Platinen hat eine als Werkstückauflage dienende Biegeleiste (2), ein als Niederhalter wirkendes Werkzeug (3) und wenigstens eine die Biegebewegung durchführende Biegewange (6), mit welcher die auf der Biegeleiste (2) aufliegende Platine um das Werkzeug (3) schwenkbar und biegbar ist. Das Werkzeug (3) weist dabei eine erste Gruppe von Segmenten (7) auf, die austauschbar sind und/oder wenigstens einen quer zur Biegelinie (B) und parallel zu ihren Seitenflächen (5) verlaufenden Schlitz (8) mit einer derartigen Weite und Tiefe aufweisen, daß ein umgebogener Rand (1a) eines Werkstückes (1) in diesen Schlitz (8) paßt. Ferner gehört zu dem Werkzeug (3) eine zweite Gruppe von Segmenten (9), die in Richtung der Biegelinie (B) relativ zueinander und zu den Segmenten (7) der ersten Gruppe verstellbar sind, wobei die Summe der maximalen und begrenzten Stellwege aller zu dem Werkzeug (3) gehörenden Segmente (9) der in Richtung der Biegelinie (B) vorgesehenen Breite eines austauschbaren Segmentes (7) oder des in dieser Richtung angeordneten Abstandes eines Schlitzes (8) von der oder den Seitenflächen (5) eines einmal geschlitzten Segmentes (7) oder des Abstandes eines Schlitzes (8) von seinem Nachbarschlitz (8) eines mehrfach geschlitzten Segmentes (7) entspricht, so daß in Richtung der Biegelinie stufenlos beliebig bemessene Werkstücke (1) bearbeitet werden können.

Figure 00000001
A bending machine for multi-sided bending, in particular swivel bending, of plate-shaped workpieces (1) or blanks has a bending bar (2) serving as a workpiece support, a tool (3) acting as a hold-down device and at least one bending beam (6) which carries out the bending movement and with which the the bending bar (2), the board resting on the tool (3) is pivotable and bendable. The tool (3) has a first group of segments (7) that are interchangeable and / or at least one slot (8) that runs transversely to the bending line (B) and parallel to its side surfaces (5) and has such a width and depth have that a bent edge (1a) of a workpiece (1) fits into this slot (8). The tool (3) also includes a second group of segments (9), which are adjustable in the direction of the bending line (B) relative to one another and to the segments (7) of the first group, the sum of the maximum and limited travel ranges for all the tool (3) belonging segments (9) of the width of a replaceable segment (7) provided in the direction of the bending line (B) or the distance of a slot (8) arranged in this direction from the side surface (s) (5) of a once slotted segment (7) or the distance of a slot (8) from its neighboring slot (8) corresponds to a multi-slotted segment (7), so that any dimensioned workpieces (1) can be machined in the direction of the bending line.
