Abstract

A CNC-controlled chamfering device for plate-shaped workpieces contains a stamp (13) driven by control elements and a thickness measurement device (11) which is movable along the circumference of the workpiece (15) at different distances from it. The thickness measurement device is connected to a computer in a device for controlling the control elements. The measurement device can be operated by hand. It is tongs-shaped and has an insertion aperture (15) with a variable stop (16) for the workpiece to be measured.

Description

Die Erfindung betrifft eine Abkanntvorrichtung entsprechend dem Oberbegriff des Anspruchs 1.The invention relates to a stripping device the preamble of claim 1.

Es ist bekannt, daß bei Abkanntvorrichtungen der Biegewinkel über die gesamte Länge der Biegelinie nicht konstant ist, wenn die Dicke eines zu bearbeitenden plattenförmigen Werkstücks unterschiedlich ist.It is known that the 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.

Der Erfindung liegt die Aufgabe zugrunde, die Vorrichtung der eingangs genannten Art so auszubilden, daß auch bei Bearbeitung von plattenförmigen Werkstücken mit nicht einheitlicher Dicke gleichmäßige Biegewinkel erreicht werden.The invention has for its object the device of the type mentioned in such a way that also at Processing of plate-shaped workpieces with no uniform thickness achieved uniform bending angle will.

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.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 actuated.

Die Erfindung wird nachstehend anhand der beigefügten Zeichnung beispielsweise erläutert:The invention is described below with reference to the accompanying 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 18 verformt werden soll. Hierzu dient ein vertikal verstellbarer Stempel 13, der mittels zwei Stellgliedern 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 18 . A vertically adjustable stamp 13 is used for this purpose, 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.
