Description
Herstellung von Tafelmessern Es ist bekannt, Messerklingen paarweise durch Walzen und Schmieden im Gelenk herzustellen, wobei die Klingen mit den Angeln aneinanderhängen. Bei diesem verfahren. geht viel hochw ertiger Werkstoff verloren, da für den Kropf, um ihn gut und voll ausschmieden: zu können, eine bestimmte Werkstückabmessung erforderlich ist. Nach der Erfindung wird dieser Nachteil dadurch beseitigt, daß ein Flachstahlspaltstück mit seitenvertauschten schmäleren Enden beiderseits eines mittleren breiteren Teils auf die Klingenlänge und -breite an beiden Enden ausgewalzt und hierauf das ganze Werkstück in einem Gesenk so geschlagen wird, daß in der Längsrichtung gegeneinander versetzte Messerwerkstücke mit nebeneinanderliegenden Angeln .entstehen.Manufacture of table knives It is known to use knife blades in pairs manufacture by rolling and forging in the joint, the blades with the hinges hang together. In this procedure. a lot of high-quality material is lost, there for the bolster, in order to forge it well and fully: to be able to have a certain workpiece dimension is required. According to the invention, this disadvantage is eliminated in that a flat steel gap piece with laterally reversed narrower ends on both sides of one in the middle, wider part, rolled out to the length and width of the blade at both ends and then the whole workpiece is struck in a die so that in the longitudinal direction offset knife workpieces with adjacent hinges.
Auf der Zeichnung ist Abb. i ein Spaltstück, Abb.2 die im Doppelgelenk aus diesem Spaltstück geschmiedeten zwei Messerklingen mit Kropf und Angel, Abb. 3 eine der fertigen Klingen.In the drawing, Fig. I is a split piece, Fig. 2 the one in the double joint Two knife blades with goiter and tang, forged from this split piece, Fig. 3 one of the finished blades.
Das Verfahren geht folgendermaßen vor sich: Das in bekannter Weise aus Stahlruten ausgestanzte Spaltstück a (Abb. i) wird zuerst an seinen Enden entsprechend der Länge und der Breite der Klingen ausgewalzt. Danach wird das so bearbeitete Spaltstück zwecks Formung von Kropf b, Angel c und Klinge d in einem Doppelgelenk mittels eines Fallhammers in der aus Abb. z ersichtlichen Weise geschlagen. Sodann erfolgt in bekannter Weise die Entgratung und die Trennung der Messer voneinander (Abb. 3).The process proceeds as follows: The gap piece a (Fig. I), punched out of steel rods in a known manner, is first rolled out at its ends according to the length and width of the blades. Then the so-machined split piece is struck in a double joint by means of a drop hammer in the manner shown in Fig. Z in order to form the bolster b, tang c and blade d. This is followed by the deburring and separation of the knives from one another in a known manner (Fig. 3).
Durch das Nebeneinanderlegen der Angeln entsteht kein unnötiger Werkstoffverlust, und die Angeln können die richtige Länge erhalten, wodurch das spätere Ansetzen einer Angelverlängerung nicht mehr erforderlich ist.By laying the hinges next to each other, there is no unnecessary loss of material, and the hinges can be given the correct length, which means that they can be attached later an extension rod is no longer required.
