Description

Verfahren zur Herstellung von Schnellstahl- und Sparwerkzeugen Zur Einsparung von. Schnellstählen ist bereits vorgeschlagen worden, die Werkzeuge an der Schneide mit Plättchen zu belegen oder eine Schneide durch Schmelzsc.hweißung am Werkzeugschaft anzubringen. Diese Ausführungen haben sich in der Praxis durchaus bewährt, sie haben jedoch den Nachteil, daß das Werkzeug, sobald das Plättchen bzw. die Schnellstahlauflage verbraucht ist, völlig neu zugerichtet werden muß, womit ein bedeutender Arbeitsaufwand verbunden ist.Process for the production of high-speed steel and economy tools Zur Saving of. High speed steel has already been proposed to use the tools to cover the cutting edge with platelets or a cutting edge by fusion welding to be attached to the tool shank. These statements have definitely proven in practice proven, but they have the disadvantage that the tool, as soon as the plate or the high-speed steel layer has been used up, has to be completely redesigned, with which a significant amount of work is involved.

Erfindungsgemäß werden Schnellstahlwerkzeuge, vornehmlich Drehmesser, nun in der Weise hergestellt, daß durch Schmelzschweißen über eine größere Länge des Schaftes eine Schnellstahlauflage aufgeschweißt wird, so daß das Werkzeug um ein Vielfaches öfter nachgearbeitet werden kann. Es wird also gewissermaßen ein Verbundstab hergestellt, der, wenn erforderlich, nach dem Schweißen durch Schmieden auch noch in die entsprechende Form gebracht werden kann.According to the invention, high-speed steel tools, primarily rotary knives, now manufactured in such a way that by fusion welding over a greater length A high-speed steel support is welded onto the shaft, so that the tool is around can be reworked many times more often. So in a sense it becomes a Composite rod made, which, if necessary, after welding by forging can also be brought into the appropriate form.

Um den Schweißdrahtverbrauch möglichst gering zu halten, kann die Auftragschweißung nicht über die ganze Fläche, sondern z. B. in eine in den Schaft eingefräste Nut aufgebracht werden; dadurch ist auch der Schweißvorgang als solcher leichter durchzuführen. Ein derart ausgefrästes Messer kann bis zum endgültigen Verbrauch der Schnellstahlauflage nachgeschliffen werden; im Vergleich zu den bekannten Ausführungen entfällt das vier- bis sechsmalige Zurichten.In order to keep the welding wire consumption as low as possible, the Overlay welding not over the entire surface, but z. B. in one in the shaft milled groove are applied; this also makes the welding process as such easier to perform. Such a milled knife can go up to the final Consumption of the high-speed steel support can be reground; in the comparison In addition to the known versions, there is no need for four to six adjustments.
