Description
Die Erfindung betrifft eine Vorrichtung zum Herstellen von
geraden Luftkanalteilen mit eckigem Querschnitt aus
Blechtafeln gemäß dem Oberbegriff des Anspruchs 1, und wie
in der EP-A-496425 offenbart.The invention relates to a device for producing
straight air duct parts with an angular cross-section
Metal sheets according to the preamble of
Formteile für Luftkanäle unterscheiden sich in zwei Kategorien: Rundrohre und Rechteckrohre. Die Rechteckrohre können gerade oder gebogen sein. Die vorliegende Erfindung betrifft eine Vorrichtung zum Herstellen von geraden Rohren mit eckigem Querschnitt.Molded parts for air ducts differ in two Categories: Round tubes and rectangular tubes. The rectangular tubes can be straight or curved. The present invention relates to a device for producing straight tubes with angular cross section.
Zur Herstellung von geraden Kanalrohren mit rechteckigem Querschnitt sind sogenannte Kanalformer handelsüblich. Es handelt sich dabei um Maschinen, die mehrere Vorrichtungen kombinieren. Zunächst ist eine Abziehvorrichtung vorhanden, die das zu verarbeitende Blech vom Coil abzieht. Desweiteren ist ein Richtwerk vorgesehen, in dem die vom Coil stammende Krümmung des Blechs beseitigt wird. Daran schließt sich eine Sickenvorrichtung an, die eine oder mehrere parallele Versteifungssicken, sogenannte Z-Sicken, in das Blech einformt. Das gesickte Blech läuft dann in eine Biegebank, die das Blechband mehrmals winklig umbiegt, so daß das gewünschte Rohr entsteht. Der Biegebank ist schließlich eine Blechschere zugeordnet, die den zum Kanalteil geformten Blechabschnitt abschneidet. Das Schließen der Längsnaht erfolgt auf einer gesonderten Kanalschließmaschine.For the production of straight sewer pipes with rectangular Cross-section are so-called channel formers commercially available. It These are machines that have multiple devices combine. First there is a puller, that pulls the sheet to be processed from the coil. Furthermore a straightening unit is provided, in which the originating from the coil Curvature of the sheet is eliminated. This is followed by one Beading device on the one or more parallel Stiffening beads, so-called Z-beads, in the sheet molded. The corrugated sheet then runs into a bending bench, which bends the sheet metal strip several times at an angle, so that the desired tube is created. After all, the bending bench is one Tin snips assigned to those formed into the channel part Cut off sheet metal section. Closing the longitudinal seam takes place on a separate channel locking machine.
Mit diesen sogenannten Kanalformern lassen sich Kanalformteile mit standardisierten Längen von 1500 mm bzw. 2000 mm entsprechend der marktüblichen Coilbreiten sehr rationell herstellen. Untersuchungen haben jedoch gezeigt, daß in etwa 40 % aller Fälle Luftkanalteile benötigt werden, deren Länge nicht den Standardlängen entspricht. Diese von der Norm abweichenden Kanalteile werden handwerklich hergestellt mit separaten Scheren, separaten Sickenmaschinen und separaten Biegemaschinen. Diese Maschinen werden hintereinander in einer Fertigungslinie angeordnet und haben einen relativ hohen Platzbedarf. Die Blechtafeln werden einzeln von Maschine zu Maschine transportiert und bearbeitet. Dies ist unbefriedigend.With these so-called channel formers, Duct fittings with standardized lengths of 1500 mm or 2000 mm very much in accordance with the coil widths customary on the market produce efficiently. However, studies have shown that air duct parts are required in about 40% of all cases, whose length does not correspond to the standard lengths. This one from Duct parts deviating from the norm are handcrafted made with separate scissors, separate beading machines and separate bending machines. These machines will arranged one behind the other in a production line and have a relatively high space requirement. The metal sheets are transported individually from machine to machine and processed. This is unsatisfactory.
