Description

Die Erfindung betrifft eine CNC-gesteuerte Abkantvorrichtung entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a CNC-controlled folding device according to the preamble of claim 1.

Es ist bekannt, daß bei Abkantvorrichtungen der Biegewinkel nicht über die gesamte Länge der Biegelinie konstant ist, wenn die Dicke eines zu bearbeitenden plattenförmigen Werkstücks unterschiedlich ist.It is known that in the case of folding devices Bending angle not over the entire length of the bending line is constant if the thickness of one to be machined plate-shaped workpiece is different.

Eine Abkantvorrichtung entsprechend dem Oberbegriff des Anspruchs 1 ist aus "Blech Rohre Profile", 1989 Nr. 4, S. 345 bekannt. Mit dieser Vorrichtung kann nur ein einziger Meßvorgang pro Werkstück durchgeführt werden, und zwar mittels eines Anschlags in einem Abstand von bis zu 1000 mm von der eigentlichen Biegestelle entfernt. Dabei wird nicht berücksichtigt, daß gerade im Bereich der Biegestelle die Dicke des Werkstücks unterschiedlich sein kann.A folding device according to the preamble of Claim 1 is from "Blech Rohr Profile", 1989 No. 4, p. 345 known. With this device only one can Measurement process are carried out per workpiece, namely by means of a stop at a distance of up to 1000 mm from the actual bending point. It won't takes into account that especially in the area of the bending point Thickness of the workpiece can be different.

Der Erfindung liegt die Aufgabe zugrunde, die Vorrichtung der eingangs genannten Art so auszubilden, daß insbesondere bei nicht einheitlicher Dicke im Bereich der Biegelinie ein gleichmäßiger Biegewinkel erreicht werden kann.The invention has for its object the device of the type mentioned in such a way that in particular with a non-uniform thickness in the area of the bending line uniform bending angle can be achieved.

Gelöst wird diese Aufgabe gemäß der Erfindung durch die im Anspruch 1 angegebenen Merkmale. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.This object is achieved according to the invention by the Claim 1 specified features. Appropriate Embodiments of the invention result from the Subclaims.

Die Erfindung beruht auf der Erkenntnis, daß es möglich ist, einen gleichmäßigen Biegewinkel zu erzielen, obwohl ein Werkstück keine einheitliche Dicke hat, wenn die Stellglieder des Stempels in Abhängigkeit von der Dicke des Werkstücks betätigt werden, und zwar in unterschiedlichem Maß.The invention is based on the knowledge that it is possible is to achieve an even bend angle, though a workpiece does not have a uniform thickness if the Actuators of the stamp depending on the thickness of the Workpiece are operated, and to different degrees.

Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise erläutert:The invention is based on the Drawing explains for example:

Die Abkantvorrichtung hat einen Arbeitstisch 18, auf dem ein zu bearbeitendes plattenförmiges Werkstück 15 aufliegt, das entsprechend einer Aufnahmeöffnung 19 im Arbeitstisch bzw. in der Werkstückauflage 18 verformt werden soll. Hierzu dient ein vertikal verstellbarer Stempel 13, der mittels zweier Stellglieder 12 betätigbar ist, wie rechts in der Zeichnung gezeigt ist.The folding device has a work table 18 on which rests a plate-shaped workpiece 15 to be processed, which is to be deformed in accordance with a receiving opening 19 in the work table or in the workpiece support 18 . For this purpose, a vertically adjustable stamp 13 is used , which can be actuated by means of two actuators 12 , as shown on the right in the drawing.

Zur Ermittlung der Dicke des Werkstückes 15 dient eine zangenförmige, handbetätigbare Meßeinrichtung 11, die mit dem Rechner der Abkantvorrichtung verbunden ist (nicht gezeigt). Die Meßeinrichtung 11 hat eine Einschuböffnung 14 für das Werkstück 15. Die Einschubtiefe der Öffnung 14 ist durch einen verstellbaren Anschlag 16 begrenzt. Die Dicke des Werkstückes 14 wird in nicht näher gezeigter Weise mittels eines vertikal verstellbaren Taststiftes 17 ermittelt.A forceps-shaped, manually operated measuring device 11 , which is connected to the computer of the folding device (not shown), is used to determine the thickness of the workpiece 15 . The measuring device 11 has an insertion opening 14 for the workpiece 15 . The insertion depth of the opening 14 is limited by an adjustable stop 16 . The thickness of the workpiece 14 is determined in a manner not shown by means of a vertically adjustable stylus 17 .

Die über den Umfang des Werkstücks 15 an bestimmten Meßstellen aufgenommenen Meßergebnisse werden mittels eines Programms ausgewertet, und in Abhängigkeit hiervon werden die Stellglieder gegebenenfalls unterschiedlich betätigt, um eine gleichmäßige Verformung des Werkstückes trotz unterschiedlicher Dicken zu erreichen.The measurement results recorded at certain measuring points over the circumference of the workpiece 15 are evaluated by means of a program, and depending on this, the actuators may be actuated differently in order to achieve a uniform deformation of the workpiece despite different thicknesses.
