Description
863929863929
Die Messerklingenrohlinge wurden bisher durch Schmieden hergestellt, was aber recht unwirtschaftlich wegen des Abbrandes, des Abfalles und des Kohlenverbrauchs ist. Gegenstand der Erfindung ist nun ein Verfahren zur Herstellung dieser Messerklingenrohlinge durch Walzen. Man hat wohl auch schon versucht, die Rohlinge zu walzen, indessen war es nicht möglich, die KonizitätThe knife blade blanks were previously made by forging, but what is quite uneconomical because of the burnup, waste and coal consumption. The invention now relates to a method for producing these knife blade blanks by rolling. Attempts have also been made to roll the blanks, in the meantime it was not possible to get the taper
ίο nach zwei Seiten hin zu erzeugen. Und wenn dies nicht geschieht, dann müssen die Rohlinge wieder einer erheblichen Schleifarbeit unterzogen werden.ίο to generate on two sides. And if If this does not happen, then the blanks again have to undergo considerable grinding work be subjected.
•Das Verfahren gemäß der Erfindung kennzeichnet sich nun dadurch, daß der Rohling, dessen Breite zur Spitze hin abnimmt und ungefähr der Hälfte der herzustellenden Klinge entspricht, aus Flachstahl in kaltem Zustande in nach zwei Seiten konischer Form längs zu den Walzen liegend ausgewalzt, deren Profil so ausgebildet ist, daß der tiefere Teil in der Drehrichtung vorn liegt.• The method according to the invention is now characterized in that the blank, the width of which decreases towards the tip and about half of that to be produced Blade corresponds, made of flat steel in cold condition with a conical shape on two sides Rolled out lying lengthways to the rollers, the profile of which is designed so that the deeper part is at the front in the direction of rotation.
Zweckmäßig nur in die eine Walze ist das Profil des Messerklingenrohlings längs zur Walzenachse flachliegend eingearbeitet, und zwar am besten so, daß der Messerrücken in der Drehrichtung vorn liegt. Das aus Flachstahl geschnittene Werkstück wird in kaltem Zustande durch einen Drücker gegen den Walzenspalt geschoben, bis die Walzen es fassen und einziehen. Es wird dann zum Klingenrohling flach. gewalzt, der nicht nur nach der Schneide, sondern auch nach der Spitze hin der endgültigen Messerform entsprechend verjüngt ißt. Dieser Rohling ist völlig glatt und blank, so daß er nur wenig übergeschliffen zu werden braucht.The profile of the knife blade blank is expediently only in one roller along the Roll axis incorporated flat, preferably so that the knife back in the direction of rotation is at the front. The workpiece cut from flat steel is in cold Condition pushed against the nip by a pusher until the rollers grasp it and pull it in. It then becomes the Blade blank flat. rolled, not only after the cutting edge, but also after the Tip eats tapered towards the final knife shape. This blank is completely smooth and shiny, so that it only needs to be sanded down a little.
