Description
Nachgiebiger eiserner Grubenstempel. Die Erfindung betrifft einen nachgiebigen eisernen Grubenstempel mit einem im Querschnitt halbkreisrunden Oberteil.Resilient iron pit stamp. The invention relates to a yielding iron pit die with a semi-circular upper part in cross-section.
Das Neue besteht in einem Unterteil, bei dem im Querschnitt an den halbkreisrunden Teil Stege mit winkelrecht nach innen abgebogenen Flanschen angeschlossen sind. Hierdurch wird ermöglicht, den Unterteil durch Pressen herzustellen sowie die Werkstoffe möglichst wirtschaftlich auszunutzen.The new consists in a lower part, in which the cross-section of the semicircular part of webs connected with flanges bent inwards at right angles are. This makes it possible to manufacture the lower part by pressing as well to use the materials as economically as possible.
In der Zeichnung stellt Abb. i den Stempel nach der Erfindung in Vorderansicht und teilweisem Schnitt und in Abb. z in senkrechtem Langschnitt dar, während Abb. 3 einen Querschnitt nach A-B der Abb. z veranschaulicht.In the drawing, Fig. I shows the stamp according to the invention in a front view and partial section and in Fig.z in a vertical long section, while Fig. Figure 3 illustrates a cross-section along A-B of Figure z.
Obwohl der Stempelunterteil einerseits offene Gestalt hat, was zum Beobachten des Stempelinnern vorteilhaft ist, wird bei verhältnismäßig geringer Blechstärke ein hohes Trägheitsmoment dadurch erreicht, daß an den halbkreisrunden Teil a Stege d mit winkelrecht abgebogenen Flanschen a" angeschlossen sind (Abb.3).Although the lower part of the punch has an open shape, which is advantageous for observing the inside of the punch, a high moment of inertia is achieved with a relatively small sheet metal thickness in that webs d with flanges a "bent at right angles are connected to the semicircular part a (Fig.3).
