Description

Herstellung von Messerklingen. Zusatz zum Patent 28622o. Nach dem Hauptpatent werden gewÖhnliche glatte Stahlbänder durch Walzen hindurchgeführt, welche in einem einzigen Arbeitsvorgange das Stahlband abwechselnd zu einer rechtwinkligen und zu einer gespitzten Querschnittsform walzen, worauf aus den so gewalzten Stahlbändern paarweise die Messer ausgeschnitten werden. Aus den Teilen des Stahlbandes, die zugespitzte Querschnittsform besitzen, werden immer zwei Klingen ausgeschnitten, während durch die rechtwinkligen Querschnittsformen die Messergänge der beiden Klingen gebildet werden.Manufacture of knife blades. Addendum to patent 28622o. After this Main patent, ordinary smooth steel strips are passed through rollers, which in a single operation alternates the steel strip to a right-angled and roll them into a pointed cross-sectional shape, whereupon the steel strips so rolled the knives are cut out in pairs. From the parts of the steel belt that have a pointed cross-sectional shape, two blades are always cut out, while through the right-angled cross-sectional shapes, the knife turns of the two blades are formed.

Nach dem Hauptpatent erhält der zugespitzte ausgewalzte Teil des Stahlbandes einen rhombischen Querschnitt, so daß die beiden gleichzeitig ausgeschnittenen Klingen mit ihren Rücken in der Mitte des Stahlbandes liegen. Nach der Erfindung findet dagegen die Verjüngung des Querschnittes des zugespitzten Teiles zur Mitte hin statt, so daß die beiden gleichzeitig ausgeschnittenen Klingen mit ihren Schneiden nach innen liegen. Diese Ausgestaltung des Verfahrens ist günstig, weil nur ein ganz geringer Streifen des zu walzenden Bandes auf die Stärke der Messerschneide gewalzt zu werden braucht, während sich der übrige Werkstoff leicht nach beiden, Seiten herausquetscht.According to the main patent, the pointed, rolled-out part of the steel strip is given a rhombic cross-section so that the two blades cut out at the same time lie with their backs in the middle of the steel belt. According to the invention takes place on the other hand, the tapering of the cross-section of the pointed Part towards the middle, so that the two blades cut out at the same time with their edges are inward. This arrangement of the procedure is favorable, because only a very small strip of the strip to be rolled on the thickness of the knife edge needs to be rolled, while the rest of the material is easy to Pages squeezed out.

In der Zeichnung zeigen wieder die Abb. i und 2 ein Werkstück gemäß der Erfindung in Aufsicht und in einem Schnitt nach Linie A-8 der Abb. i, während die Abb. 3 und q. ein Walzenpaar zur Erzeugung der Werkstücke nach Abb. i und 2 in einem Schnitt nach Linie C-D der Abb. q. und in einer Stirnansicht zeigen. .In the drawing, FIGS. I and 2 again show a workpiece according to of the invention in plan and in a section along line A-8 of Fig. i, while Fig. 3 and q. a pair of rollers for producing the workpieces according to fig. i and 2 in a section along line C-D of Fig. q. and show in a front view. .

Die Teile a des Stahlbandes sind wieder die planparallel begrenzten Stücke, welche dem Messergang ents?rechen, während die zugespitzten Teile b den Klingen entsprechen. Die Messerklingen c sind in Abb. i punktiert eingezeichnet, c1 sind ihre Schneiden, d bezeichnet den Messergang, e die Oberwalze, f die Unterwalze, g die Ausnehmungen der beiden Walzen zur Bildung der zugespitzten Teile b und h die Ausnehmungen zur Bildung der rechtwinkligen Querschnittsform a.The parts a of the steel strip are again delimited plane-parallel Pieces which correspond to the thread of the knife, while the pointed parts bend Blades match. The knife blades c are drawn in dotted in Fig. I, c1 are their cutting edges, d denotes the knife pass, e the upper roller, f the lower roller, g the recesses of the two rollers to form the pointed parts b and h the recesses to form the right-angled cross-sectional shape a.

Wie aus Abb. q. ersichtlich, besitzen die Ausnehmungen g der Walzenringe, welche die Gestaltung des Teiles b bezwecken, ihren höchsten Punkt in der Mitte des Profils. Dadurch entstehen beim Walzen gemäß Abb. 2 abwechselnd mit den Planstücken a die Teile b, welche im Querschnitt die Gestalt zweier gleichschenkliger Dreiecke haben, die mit den Spitzen aneinanderliegen. Die Klingen werden also mit der Schneide cl nach innen liegen.As shown in Fig. Q. can be seen, have the recesses g of the roller rings, which aim at the design of part b, their highest point in the middle of the profile. This results in alternating with the plan pieces when rolling according to Fig. 2 a the parts b, which in cross section have the shape of two isosceles triangles with their tips against each other. So the blades are with the cutting edge cl lie inwards.
