Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung der WÜlste und Wasserfalze an durch Tiefziehen geformten Rohlingen für einteilige Dachrinnenwinkel, deren Seitenwände im Bereich der Eckverbindung der aufeinanderstoßenden Dachrinnenwinkelstücke, vorzugsweise kreisbogenförmig ausgebildet sind.The invention relates to a method and a device for producing the beads and seams on blanks formed by deep drawing for one-piece gutter angles, the side walls of which are preferably circular in the area of the corner connection of the abutting gutter angle pieces.

Um das bei der Herstellung von Dachrinnenwinkeln aus zwei spitzwinklig gegeneinanderstoßenden halbrunden Dachrinnenstücken übliche Löten oder Schweißen der in Gehrungsrichtung verlaufenden Verbindungsnaht wegen der damit verbundenen Nachteile bezüglich Montage und Langzeitdichtigkeit zu vermeiden, ist in dem DE-GM 78 11 514 ein Dachrinnenwinkel zur Verbindung halbrunder Dachrinnen vorgesehen, der durch Tiefziehen-von Blechmaterial hergestellt und bei dem die Seitenwände im Bereich ihrer Ecken jeweils kreisbogenförmig gestaltet sind. Bei einem solchen Dachrinnenwinkel bleiben an den Längsrändern freie Randbereiche überstehen, die nach entsprechendem Besäumen zu Wülsten gewickelt bzw. Wasserfalzen angekantet werden. Abgesehen davon, daß diese Biegearbeiten im allgemeinen unter Anwendung herkömmlicher Dachdecker-Werkzeuge und -Hilfsmittel durchgeführt werden, ist auch schon versucht worden, Wülste und Wasserfalze unter Einsatz geeigneter Maschinen zu wickeln bzw. anzukanten, wobei in nachteiliger Weise sowohl für die Herstellung der Wülste als auch für die Herstellung der Wasserfalze jeweils mehrere Arbeitsgänge notwendig sind. Das bedeutet einen relativ hohen Aufwand an manueller Tätigkeit und Zeit und entspricht nicht einer nach zeitgemäßen Gesichtspunkten durchzuführenden Fertigung.In order to avoid the usual soldering or welding of the connecting seam running in the miter direction when producing gutter angles from two semicircular gutter pieces butting against each other at an acute angle because of the associated disadvantages with regard to assembly and long-term tightness, a gutter angle for connecting semicircular gutters is provided in DE-GM 78 11 514 , which is produced by deep-drawing sheet metal material and in which the side walls are each designed in the form of a circular arc in the region of their corners. With such a gutter angle, free edge areas remain on the longitudinal edges, which are wound into beads or edging folded after appropriate trimming. In addition to the fact that this bending work is generally carried out using conventional roofing tools and aids, attempts have also been made to wrap beads and water seams using suitable machines, disadvantageously for the manufacture of the beads as well several operations are also required for the production of the water seams. This means a relatively high amount of manual work and time and does not correspond to a production to be carried out according to contemporary criteria.

Es ist die Aufgabe der vorliegenden Erfindung, das Formen der Wülste und Wasserfalze an durch Tiefziehen hergestellten Rohlingen für einteilige Dachrinnenwinkel schnell, einfach und mit möglichst niedrigem Aufwand durchzuführen, insbesondere sollen auch angelernte Arbeitskräfte mit diesen Arbeiten betraut werden können.It is the object of the present invention to form the beads and water seams on blanks produced by deep drawing for one-piece gutter angles quickly, easily and with as little effort as possible, in particular also skilled workers should be able to be entrusted with this work.

Die Lösung dieser Aufgabe besteht darin, daß die freien, überstehenden, besäumten Längsrandbereiche der Rohlinge für einteilige Dachrinnenwinkel bauabseitig zu Wülsten und bauseitig zu Wasserfalzen automatisch gewickelt bzw. gebogen werdenThe solution to this problem is that the free, protruding, trimmed longitudinal edge regions of the blanks for one-piece gutter angles are automatically wound or bent on site by the customer and on site by water seams

Die Vorrichtung zur Durchführung dieser Verfahrensmaßnahmen umfaßt ein Unterwerkzeug und ein Oberwerkzeug. Das Unterwerkzeug besteht aus einem ortsfest angeordneten, dem Außenprofil des Rohlings angepaßten, unteren Formteil und einem neben diesem auf der Seite des zu formenden Wasserfalzes angeordneten, heb-/senkbaren Hochstellformteil. Das Oberwerkzeug ist durch ein heb-/senkbares, dem Innenprofil des Rohlings angepaßtes, auf das untere Formteil spannbares, oberes Formteil gebildet, bei dem auf der Seite des zu formenden Wasserfalzes in einer Ausnehmung ein heb-/senkbarer Stützbalken angebracht ist. Auf den Seiten der zu wickelnden Wülste befindet sich jeweils ein mit einem Längsschlitz versehener, auf die Kanten der freien Längsrandbereiche aufschiebbarer, längs- und querverschieblicher, drehbarer Winkelstab. Auf den Seiten der zu formenden Wasserfalze ist jeweils ein mit einem Längsschlitz versehener, auf die Kanten der freien Längsrandbereiche aufschiebbarer, längsverschieblicher, drehbarer Biegestab angeordnet.The device for carrying out these procedural measures comprises a lower tool and an upper tool. The lower tool consists of a fixed lower part, which is adapted to the outer profile of the blank, and a liftable / lowerable raised part, which is arranged next to it on the side of the water fold to be formed. The upper tool is formed by an upper mold part which can be raised / lowered and which is adapted to the inner profile of the blank and can be clamped to the lower mold part, in which a lifting / lowerable support beam is attached. On the sides of the beads to be wound there is in each case a rotatable angled rod provided with a longitudinal slit, which can be pushed onto the edges of the free longitudinal edge regions and is longitudinally and transversely displaceable. Arranged on the sides of the water folds to be formed is a longitudinally displaceable, rotatable bending rod provided with a longitudinal slot and slidable onto the edges of the free longitudinal edge regions.

Zur Herstellung der Wasserfalze an Rohlingen für Dachrinneninnenwinkel bestehen das Hochstellformteil und der Stützbalken jeweils aus zwei im Bereich der Ecken getrennten, heb-/senkbaren Bauteilen.For the production of the water seams on blanks for gutter angles, the raised part and the support beam each consist of two components that can be lifted / lowered in the corners.

Zweckmäßigerweise ist zur Herstellung der Wülste an Rohlingen für Dachrinneninnenwinkel im Bereich der Ecken des unteren und oberen Formteils jeweils eine heb-/senkbare Stützbacke für das Einklemmen der freien Längsrandbereiche angeordnet, die jeweils eine parallel zur Achse des Rohlings verlaufende U-förmige Ausnehmung aufweisen, so daß in Klemmstellung ein Kanal zwischen beiden Stützbacken vorhanden ist, in den die Wickelstäbe eingefahren und auf die Längsrandbereiche aufgeschoben werden können.Appropriately, for the production of the beads on blanks for gutter angles in the area of the corners of the lower and upper molded part, a lifting / lowering support jaw is arranged for clamping the free longitudinal edge areas, each of which has a U-shaped recess running parallel to the axis of the blank, so that in the clamping position there is a channel between the two support jaws, into which the winding bars can be inserted and pushed onto the longitudinal edge areas.

Nach einem weiteren Merkmal der Erfindung sind das untere und das obere Formteil auswechselbar, so daß eine Anpassung an unterschiedlichen Profile der Rohlinge für Dachrinnenwinkel möglich ist.According to a further feature of the invention, the lower and the upper molded part are interchangeable, so that an adaptation to different profiles of the blanks for gutter angles is possible.

Im Rahmen der besonderen Ausgestaltung der erfindungsgemäßen Vorrichtung sind die auf Querschlitten befindlichen Wickelstäbe und die Biegestäbe zusammen mit ihren Antrieben auf Längsschlitten angeordnet, wobei die Querschlitten auf einer zum unteren Formteil hin geneigt angebrachten Bahn verfahrbar sind.In the context of the special configuration of the device according to the invention, the winding bars located on cross slides and the bending bars are arranged on their longitudinal slides together with their drives, the cross slides being movable on a track inclined towards the lower molding.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die an tiefgezogenen Rohlingen für Dachrinnenwinkel anzuformenden Wülste und Wasserfalze schnell, einfach und mit vergleichsweise geringem Aufwand herstellbar sind. Es sind lediglich erforderlich, daß die Rohlinge von Hand in das untere Formteil eingelegt werden; danach laufen alle Formgebungsvorgänge automatisch ab.The advantages achieved with the invention consist in particular in that the beads and water seams to be molded on deep-drawn blanks for gutter angles can be produced quickly, easily and with comparatively little effort. It is only necessary that the blanks are inserted into the lower molding by hand; then all shaping processes run automatically.

Im folgenden ist jeweils ein Ausführungsbeispiel für einen Dachrinnenaußenwinkel und einen Dachrinneninnenwinkel beschrieben und anhand der Zeichnungen näher erläutert.In the following, an embodiment for an outer gutter angle and an inner gutter angle is described and explained in more detail with reference to the drawings.

Danach werden über den Zylinder 34, 34' die den anderen Teil des Oberwerkzeugs bildenden, auf der Seite des zu formenden Wasserfalzes angeordneten heb-/senkbaren zwei Stützbalkenteile 35, 35' in die Ausnehmung 36 des Formteils 33 abgesenkt. Anschließend werden über die Zylinder 37, 37' die auf der Seite des zu formenden Wasserfalzes neben dem unteren Formteil 31 angebrachten, einen Teil des Unterwerkzeugs bildenden heb-/senkbaren zwei Hochstellformteil 38, 38' nacheinander hochgefahren, so daß die freien Längsrandbereich 28, 28' des Rohlings 27 etwa parallel zur senkrechten Mittelebene stehend so geformt werden, daß sie sich im Eckbereich überlappen. Gleichzeitig werden die für die Wulstbildung vorgesehenen freien Längsrandbereiche 29, 29' zwischen den jeweils mit einer U-förmigen, parallel zur Achse des Rohlings 27 verlaufenden Ausnehmung 39, 40 versehenen, heb-/senkbaren Stützbacken 41, 42 festgeklemmt. Nachdem die Stützbalkenteile 35, 35' und die Hochstellformteile 38, 38' wieder in Ausgangsstellung gefahren sind, fahren die auf den Führungen 43, 43', 44, 44' gelagerten Längsschlitten 45, 45' mittels der Zylinder 46, 46' ein, so daß die Längsschlitze der Biegestäbe 47, 47' und Wickelstäbe 48, 48' auf die Kanten der freien Längsrandbereiche 28, 28', 29, 29' des Rohlings aufgeschoben werden, wobei die Wickelstäbe 48, 48' jeweils in den durch die beiden Ausnehmungen 39, 40 gebildeten Kanal einfahren. Sobald die Stützbacken 41, 42 wieder die Ausgangsstelllung eingenommen haben, werden die Wickelstäbe 48, 48' durch die Antriebe 49, 49' und der Biegestab 47 durch den Antrieb 50 gedreht, wodurch die Wülste 51, 51' und ein Wasserfalz 52 geformt werden. Dabei werden die jeweils auf einem Querschlitten 53, 53' befindlichen Wickelstäbe 48, 48' zum Dachrinnenwinkel hin auf einer schiefen Ebene bewegt.
