Description

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung von Schirmkronen und besteht im wesentlichen darin, daß zur Herstellung dünnes Blech verwendet und die für den Kronenteil erforderliche Stärke des Materials durch Stauchen des Preßlings in einer Zwischenstufe der Erzeugung gewonnen wird. Weiter besteht die Erfindung auch noch darin, daß die Schlitze für die Aufnahme der Schinnschienen im Kronenteil mittels eines geschützten Ringstempels ausgestanzt werden können. Um diese Herstellungsart zu erleichtern, ist der Innendurchmesser des Kronenteiles vorteilhaft wenig größer als der Außendurchmesser der gezogenen Kronenhülse. The invention relates to a method for manufacturing umbrella crowns and consists essentially in the fact that thin sheet metal is used for production and that for the crown part required strength of the material by upsetting the compact in a Intermediate generation is obtained. The invention also consists in that the slots for receiving the track rails can be punched out in the crown part by means of a protected ring punch. To facilitate this type of production, the inside diameter of the crown part is advantageously slightly larger than the outside diameter of the drawn crown sleeve.

Damit ergeben sich ganz wesentliche Vorteile gegenüber der bisherigen Erzeugungsart, die durch die Verwendung billigeren Materials eine leichtere Bearbeitungsmöglichkeit desselben und raschere Erzeugung bedingt ist.This results in very significant advantages compared to the previous type of generation, which is easier to process by using cheaper material the same and faster generation is conditioned.

In der Zeichnung ist veranschaulicht, in welcher Art eine Scheibe 1 (Abb. 1) aus dünnem Blech zu einer Schirmkrone geformt wird. Die Scheibe wird zunächst zu einer halbkugelförmigen Kappe 2 (Abb. 2) gedrückt.The drawing illustrates the type of disc 1 (Fig. 1) made from thin sheet metal is formed into an umbrella crown. The disc first becomes a hemispherical cap 2 (Fig. 2).

In einem weiteren Arbeitsgange (Abb. 3) wird der Kappenboden 3 gegenüber dem Kappenrand 4 verschmälert abgesetzt und in einem darauffolgenden Arbeitsgange (Abb. 4) das genaue Grundprofil der Schirmkrone hergestellt, indem der Kappenboden 3 zylindrische Umriß form erhält und der Kappenrand 4 durch Zusammenwirken von Gesenk S und Stauchstempel 6 gestaucht wird. Der Kappen-In a further operation (Fig. 3) the cap base 3 is opposite the cap edge 4 is reduced and in a subsequent operation (Fig. 4) the exact basic profile of the umbrella crown produced by the cap base 3 cylindrical Outline shape is obtained and the cap edge 4 through the interaction of the die S and Upsetting punch 6 is upset. The cap

rand 4 hat dadurch die Wandstärke erhalten, die für das nachherige Bearbeiten nötig ist.rand 4 has received the wall thickness that is necessary for subsequent processing.

. In einem weiteren Arbeitsgange (Abb. 5) wird der Kappenboden gelocht und durch gleichzeitige Ziehwirkung die Hülse 7 gebildet.. In a further step (Fig. 5) the bottom of the cap is perforated and through simultaneous pulling action, the sleeve 7 is formed.

Die Schirmkrone hat auf diese Weise ihre Grundform erhalten. Nun wird in den Kronenteil 4 die Nut 8 eingedreht (Abb. 6) und hierauf mittels eines Messeretempels 9 der Kronenteil durch Ausschneiden bestimmter Stücke geschlitzt (Abb. 7), welche als Abfall von dem Kronenteil herausgeschnitten werden.The umbrella crown has received its basic shape in this way. Now is in the crown part 4 screwed in the groove 8 (Fig. 6) and then by means of a knife stamp 9 of the Crown part slit by cutting out certain pieces (Fig. 7), which are considered waste be cut out from the crown part.
