Description
Die Walzen n> Wx des in den Fig. 2 und 3 der Zeichnung veranschaulichten, an sich bekannten Walzwerks haben an ihrem Umfang Erhöhungen h bezw. Zz1, wovon die eine die Form des zu fertigenden Hobeleisens versenkt, die andere erhöht erhält, und welche bei der Drehung der Walzen in einander greifen, dann aber einen Raum zwischen sich lassen, der der Form des Hobeleisens entspricht. Wird das Stück Eisen mit dem in einem bestimmten Abstand vom Ende aufgelegten Stahl bei der Stellung der Walzen Fig. 3, wie oben bemerkt, mit dem Ende I vorauf zwischen die Walzen gebracht, so drückt es sich in die in den Erhöhungen enthaltene Form. Dem Lauf der Walzen entsprechend, wird der Stahl in einer Schicht nach dem anderen Ende II hin gewalzt und aufgeschweifst, und zwar fällt hierbei die erzielte Verstählung derartig aus, dafs ein Nachschmieden , wie es bei den in Stangen gewalzten und verstählten, sowie bei den von verstählten Blechen abgeschnittenen Hobeleisen der Fall ist, nicht mehr erforderlich ist.The rollers n> W x of the illustrated in FIGS. 2 and 3 of the drawing, known per se have elevations h respectively on their circumference. Zz 1 , one of which sinks the shape of the plane iron to be manufactured, the other is increased, and which interlock when the rollers rotate, but then leave a space between them that corresponds to the shape of the plane iron. If the piece of iron with the steel placed at a certain distance from the end is brought between the rollers with the end I first in the position of the rollers in FIG. 3, as noted above, it is pressed into the shape contained in the elevations. Corresponding to the course of the rolls, the steel is rolled in one layer towards the other end II and tapered, and the steeling achieved here is such that re-forging, as is the case with the bars rolled and steeled, as well as those of steeled sheets cut off plane irons is no longer necessary.
Paτεnt-Anspruch:Paτεnt claim:
Ein Verfahren zur Herstellung von Hobeleisen durch Walzen, dadurch gekennzeichnet, dafs jedes Hobeleisen für sich aus einem Stück Eisen (a) von entsprechenden Dimensionen, auf welches der Stahl (b) in einiger Entfernung von dem später die Schneide abgebenden Ende aufgelegt ist, gewalzt wird, indem es mit dem anderen Ende zwischen entsprechend geformte Walzen eingeführt, diese bis zum Schneidenende passirt, wobei der Stahl nach letzterem hin ausgewalzt und aufgeschweifst wird.A process for the production of plane irons by rolling, characterized in that each plane iron is rolled from a piece of iron (a) of corresponding dimensions on which the steel (b) is placed at some distance from the end that will later release the cutting edge by inserting it with the other end between appropriately shaped rollers, passing them up to the end of the cutting edge, the steel being rolled out towards the latter and tapered.
