Patentiert im Deutschen Reiche vom 26. August 1906 ab.Patented in the German Empire on August 26, 1906.

Bekanntlich geschieht das Richten von Flach- und Universaleisen bisher in der Weise, daß das Richtgut aus der Walze auf eine mit Ansätzen versehene Richtbank aufläuft und dort durch Anpressen gegen diese Ansätze in der Hochkantrichtung und ev. mittels Holzhämmern in der Flachrichtung von Hand gerichtet wird. Diese Art des Richtens erfordert nicht nur mehr oder weniger menschliche Arbeitskräfte und Zeitaufwand, sondern es kann auch ein genaues Richten, besonders auf allen Seiten, nicht erzielt werden. Zum Richten in der Flachrichtung wendet man wohl auch besondere Rollenrichtmaschinen an, derart, daß man das Richtgut zunächst durch diese Rollenrichtmaschine hindurchschickt und daran anschließend die Hochkantrichtung auf der Richtbank in oben geschilderter Weise vornimmt. As is well known, the straightening of flat and universal iron has so far been done in the way that the material to be straightened from the roller runs onto a straightening bench provided with lugs and there by pressing against these approaches in the upright direction and possibly using wooden hammers is straightened by hand in the flat direction. This type of judging not only requires more or less human labor and time investment, but it can also be an accurate straightening, especially at all Pages, not being scored. For straightening in the flat direction one probably also turns special roller straightening machines in such a way that the material to be straightened is first passed through this Roll straightener sends through and then the edgewise direction on the Makes straightening bench in the manner described above.

Es ist ferner bereits eine Richtmaschine bekannt, bei welcher maschinell sowohl die Hochkantrichtung als auch die Flachrichtung, und zwar nach beiden Seiten unabhängig voneinander erfolgt. Es sind jedoch hierzu zwei Richtklötze bzw. Richtlineale notwendig, und es muß jedesmal, wenn eine Seite des Arbeitsstückes gerichtet wird, vorher der Richtklotz für die andere Seite außer Wirkung gesetzt werden.It is also already known a straightening machine in which both the Both the upright direction and the flat direction, on both sides independently of one another he follows. However, two alignment blocks or rulers are necessary for this, and every time one side of the workpiece is straightened, the straightening block must be used beforehand be overridden for the other side.

Bei einer weiteren Einrichtung werden Druckplatten benutzt, die in schräger Richtung auf das zu richtende, auf der Richtbank befindliche, noch glühende Werkstück gepreßt werden und sowohl das Flach- als auch Hochkantrichten besorgen sollen. Diese Einrich- tung hat den Nachteil, daß der schräge Druck sich stets in demselben Verhältnis in senkrechte und wagerechte Komponenten zerlegt, ohne Rücksicht auf die verschiedenen Breiten und Dicken des Walzgutes bzw. auf die jeweilige Deformation des Werkstückes. Der Druck am vorderen Ende der Druckplatten ist bedeutend geringer als an der Stelle, an welcher die Kraft angreift, so daß ein genaues Geraderichten nicht gewährleistet ist. Dadurch ist aber auch ein erhöhter Kraftverbrauch und ein erhöhter Verschleiß der Richtbank bedingt.Another device uses pressure plates that are inclined in the direction pressed onto the still glowing workpiece to be straightened on the straightening bench and should take care of both the flat and upright straightening. This facility processing has the disadvantage that the oblique pressure is always in the same proportion in the vertical and horizontal components disassembled, regardless of the different widths and thicknesses of the rolling stock or the respective deformation of the workpiece. Of the Pressure at the front end of the pressure plates is significantly less than at the point where it is the force attacks, so that an exact straightening is not guaranteed. Through this but is also an increased power consumption and an increased wear of the straightening bench conditional.

Gemäß vorliegender. Erfindung erfolgt nun das Richten des Gutes in beiden Richtungen vollständig unabhängig voneinander durch ein und dasselbe Richtlineal, welches währenddes Richtens auf dem Gut verschoben werden kann und somit eine glättende Wirkung auf das Gut ausübt. Durch die neue Vorrichtung ist· es möglich, mit einem dem jeweiligen Zustande des Richtgutes genau angepaßten Druck zu arbeiten. Infolgedessen ist der Kraft- und Arbeitsaufwand geringer als bei den bekannten Richtvorrichtungen.According to the present. Invention is now the straightening of the goods in both directions completely independent of each other by one and the same rule of thumb, which during the Straightening can be moved on the property and thus a smoothing effect on the Exercises well. The new device makes it possible to work with one of the respective states to work precisely adjusted pressure of the target material. As a result, the force and Less work required than with the known straightening devices.

In der Zeichnung ist eine als Beispiel dienende Vorrichtung zur Ausführung des Richtens dargestellt.In the drawing is an exemplary apparatus for performing the straightening shown.

A ist die an sich bekannte Richtbank, auf welcher der zu richtende Stab A¹ liegt. Längs der Richtbank ist auf einer parallel zu derselben verschiebbaren Achse E eine Reihe von Hebeln C angeordnet, die durch im Punkte F A is the well-known straightening bench on which the rod A ¹ to be straightened lies. Along the straightening bench is arranged on a displaceable parallel to the same axis E is a series of levers C represented by the points F

Claims

attacking handlebars / can be rotated around the axis E and a movable straightedge at the free end. D wear. The straightening process is now carried out in such a way that the straightening material A1 lying on the straightening bench Ä is first pressed with the narrow side by the straightening ruler D against a continuous projection B of the straightening bench, so that the goods are directed upright. After completing the upright straightening, the straight edge D is set on the flat side of the goods by means of the handlebars / and shifting the axis E, and the same is flattened in such a way that the straightedge is repeated by its own weight or by means of the handlebars / on the flat iron Required is pressed, so that each time a strip of the goods corresponding to the projection of the ruler is directed. The straightening can also be done in such a way that one moves the ruler under the pressure of its own weight or the action of the handlebars by moving the axis E over the object to be straightened and thus exerts a smoothing effect on the same, which is important for some purposes. It does not matter whether the straightening is carried out simultaneously or gradually over the entire length of the goods. The straightening process can of course also be carried out the other way round in any desired manner, depending on the condition and type of the object to be straightened. The shifting and setting of the axis E can, for example, as shown in the drawing, be carried out by hydraulic cylinders G or by mechanically moved threaded spindles, racks or other mechanical devices, while the movement of the handlebars / directly or by means of lever transmission by steam, Compressed air or hydraulic cylinder H happens. The vertical movement of the levers for the straightedge can also take place by means of thumb disks, friction gears, etc., so that the straightforward straightening is effected by their freely falling weight. The guidelines D can, depending on requirements, have the same length as the straightening bench itself or be composed of different parts that can be operated independently of one another, in such a way that, depending on the condition of the object to be straightened, individual parts of the same with more or less strong pressure independently of one another or at the same time the length of the straightening bench or part of it can be machined.
