Description

Bei dem bisher bekannten Verfahren zur Herstellung von Aushalsungen an Feuerbüchswänden oder an anderen Gegenständen aus Blech durch Pressen findet infolge Streckung des Materials eine Verminderung der Wandstärke in der Aushalsung statt. Wenn eine Verminderung der Wandstärke nicht zulässig ist, wie z. B. in den Aushalsungen an kupfernen Feuerbüchstürwänden, bei denen die Wand-In the previously known method for producing collars on firebox walls or on other sheet metal objects by pressing, the wall thickness is reduced as a result of the stretching of the material in the neck. If a reduction in the wall thickness is not permitted is, such as B. in the necks on copper firebox door walls, where the wall

ίο stärken in den Aushalsungen nicht schwächer sein dürfen, als in den übrigen Teilen der Wand, werden die Aushalsungsarbeiten von Hand ausgeführt, und es sind umständliche Vorbereitungsarbeiten an den zu verarbeitenden Blechen durch Anhäufen des Materials für die Aushalsungen an den in Frage kommenden Stellen des Bleches erforderlich.ίο strengthen in the necks not weaker than in the other parts of the wall, the extrusion work is carried out by hand, and there are cumbersome preparatory work on the sheets to be processed by piling up the material for the collars in the places in question of the sheet is required.

Die vorliegende Erfindung bezweckt, umständliche Vorbereitungsarbeiten von HandThe purpose of the present invention is to carry out cumbersome preparatory work by hand

ao nach Möglichkeit zu vermeiden und durch Maschinenarbeit mittels Pressen zu ersetzen.ao to be avoided if possible and to be replaced by machine work using presses.

In den Abb. 1 bis 4 der Zeichnung ist beispielsweise der Arbeitsgang bei der Herstellung einer kupfernen Türwand dargestellt. In Abb. 1In Figs. 1 to 4 of the drawing, for example the work process for the production of a copper door panel is shown. In Fig. 1

ist das mit einer Öffnung α versehene Blech δ in die Gesenke eingebracht. . Das Gesenk c ist in diesem Falle als feststehend, das Gesenk d als beweglich angenommen. Das Gesenk d stellt zunächst die äußere Bördelung in bekannter Weise her. In Abb. 2 ist die äußere Bördelung fertig, und die aus mehreren|Teilen bestehenden Lochwerkzeuge e, f sind im Begriff, die Türöffnung zu bilden. In Abb. 3 ist die Türöffnung ausgeführt, und das Blech b ist fest zwischen die Gesenke c und d eingeklemmt, wobei der Anschlag h mit einem Keilstück i, welches durch die Lochwerkzeuge e und f umschlossen ist, in Berührung gekommen ist. In Abb. 4 ist die Aushalsung der Türöffnung durch das bewegliche Gesenk g erfolgt. Hierbei ist;durch-den Anschlagt das Keilstück i verschoben, wodurch die einzelnen Teile der Lochwerkzeuge e und f in der Richtung des Bleches auseinander bewegt sind. Durch Aufweiten der Türöffnung wird so viel Material in die Aushalsung verdrängt, daß keine, Streckung und folglich keine Verminderung der Wandstärke in der Aushalsung eintritt.the sheet metal δ provided with an opening α is introduced into the dies. . In this case, the die c is assumed to be stationary and the die d to be movable. The die d first produces the outer flanging in a known manner. In Fig. 2 the outer flange is finished and the perforating tools e, f , consisting of several parts, are about to form the door opening. In Fig. 3 the door opening is made, and the sheet metal b is firmly clamped between the dies c and d , the stop h having come into contact with a wedge piece i, which is enclosed by the punching tools e and f. In Fig. 4 the necking of the door opening is done by the movable die g. In this case, the wedge piece i is displaced by the stop, as a result of which the individual parts of the punching tools e and f are moved apart in the direction of the sheet metal. By widening the door opening, so much material is displaced into the collar that no stretching and consequently no reduction in the wall thickness occurs in the collar.
