Description

Verfahren zum Zuspitzen der Enden von Zieh- und Walzgut. Die Erfindung betrifft ein Verfahren zum Zuspitzen bzw. Querschnittverjüngen der Enden von Zieh- und Walzgut u. dgl., z. B. Draht-, Band- und Flacheisen, Wellen und Stangen beliebigen Querschnittsprofils, und insbesondere solchen Walzgutes, das nach dem Verlassen der letzten Walze auf Haspeln aufgewickelt wird und dessen Enden deshalb nicht ohne weiteres durch mehrfaches Wenden unter einem Hammer zugespitzt werden können. Man hat für Zieh- und Walzgut dieser Art besondere Zuspitzvorrichtungen vorgeschlagen, die jedoch für jedes Walzgut immer besonders eingestellt werden müssen. Das Verfahren nach der Erfindung besteht darin, daB die zuzuspitzenden oder im Querschnitt zu vermindernden oder zu verjüngenden Enden von zwei entgegengesetzten Seiten aus in einer entsprechenden Schneidvorrichtung keilförmig flach geschnitten und darauf - der stehengebliebene Werkstoff im rechten Winkel zu den flach geschnittenen Seiten unter einer Presse oder zwischen einem -Walzenpaar konisch oder prismatisch zusammengequetscht werden. Die Enden sind ;durch diese beiden Arbeitsgänge dann so weit zugespitzt oder im Querschnitt verjüngt, daß sie ohne weiteres in ein' Zieheisen oder in eine Ziehmatrize eingeführt werden können. Welches Querschnittsprofil das Längengut besitzt, ist für die Anwendung des Verfahrens nach der Erfindung ohne Belang.Process for sharpening the ends of drawn and rolled stock. The invention relates to a method for tapering or tapering the cross-section of the ends of drawing and rolling stock and the like, e.g. B. wire, strip and flat iron, shafts and bars any Cross-sectional profile, and in particular such rolling stock that after leaving the last roll is wound on reels and therefore its ends are not without can be sharpened by turning several times under a hammer. Man has proposed special sharpening devices for drawing and rolling stock of this type, which, however, always have to be set separately for each rolling stock. The procedure according to the invention consists in that the to be pointed or in cross-section to diminishing or tapering ends from two opposite sides in a corresponding cutting device cut flat in a wedge shape and on it - the stopped one Material at right angles to the flat cut sides under a press or between a pair of rollers conical or squeezed together prismatically. The ends are; by these two operations then pointed or tapered in cross-section to such an extent that they easily turn into a ' Drawing dies or can be inserted into a drawing die. Which cross-sectional profile has the length good, is for the application of the method according to the invention without Concern.

An Hand der in den Abb: x bis 3 wiedergegebenen zeichnerischen Erläuterungen würde sich das Verfahren nach der Erfindung wie folgt gestalten: Es wird angenommen, daß es sich um ein Längenmaterial a von rechteckigem Querschnitt handelt, das an den Enden zum Zweck der Einführung in ein Zieheisen oder in eine Ziehmatrize so weit im Querschnitt vermindert oder verjüngt oder zugespitzt sein soll, daß diese Einführung ohne weiteres von Hand vorgenommen werden kann.On the basis of the graphic explanations given in Figs: x to 3 the method according to the invention would be designed as follows: It is assumed that it is a length material a of rectangular cross-section, which is an the ends for the purpose of insertion into a drawing die or die should be reduced or tapered or pointed in cross-section that this Introduction can easily be done by hand.

Zu dem Zweck wird das Ende des Stabes a zunächst an zwei entgegengesetzten Seiten in der Richtung der Abb. i strichpunktierten Schnittlinien ,4-B und C-D@ keilförmig zugespitzt. Der Stab a wird darauf unter einer Presse oder zwischen einem Walzenpaar an den beidewim rechten Winkel zu den Schnittebenen A-B und C-D liegenden Seiten breitgequetscht, und zwir entweder wieder keilförmig, wie in Abb. a, oder prismatisch, wie in Abb.3. In diesen Abbildungen ist die Ausgangsform der Enden der zu verjüngenden Stäbe a gestrichelt angedeutet.For this purpose, the end of the rod a is first connected to two opposite ones Pages in the direction of Fig. I dot-dash lines, 4-B and C-D @ wedge-shaped pointed. The rod a is placed on it under a press or between a Pair of rollers on the two lying at right angles to the cutting planes A-B and C-D Sides squashed wide, and either again wedge-shaped, as in Fig. A, or prismatic, as in Figure 3. In these figures the starting shape is the ends of the rods to be tapered a indicated by dashed lines.
