Description
Verfahren zur Herstellung von Strickmaschinennadeln Bei der Herstellung von Strickmaschiraiinadeln hat man den Drehzapfen der 1 adelzunge u. a. dadurch gebildet, daß mit einem Stempel, dessen Querschnitt kleiner ist" als derjenige der Zungenbohrung, Werkstoff aus den beiden Nadelwangen in die Zuugenboli-. rung verdrängt wird, bis sie ganz mit verdrängtem Werkstoff ausgefüllt ist, wodurch ein Bolzen entsteht, auf dem die schwingende Zunge rundum dicht aufsitzt.Method of making knitting machine needles During manufacture of knitting machirai needles one has the pivot of the 1 needle tongue u. through this formed that with a punch whose cross section is smaller "than that of the Tongue hole, material from the two needle cheeks in the Zuugenboli-. displaced until it is completely filled with displaced material, creating a bolt arises on which the swinging tongue sits tightly all around.
Damit nicht, wie bisher, bei der Verdrängung des Werkstoffes in die Zungenbohrung viel Ausschuß durch Reißen der sehr dünnen Nadeln und Zungen entsteht, regelt die Erfindung den Vorgang dieser Verdrängung üi besonderer Weise, und zwar dadurch, daß die Verdrängung mit einem an sich bekannten zweistufigen Stempel ausgeführt wird, dessen Abstufung .erfindungsgemäß so gewählt ist, daß der Querschnitt der ersten Stufe kleiner und derjenige der zweiten Stufe größer als die Zungenbohrung ist.So not, as before, with the displacement of the material into the Tongue drilling a lot of scrap is created by tearing the very thin needles and tongues, the invention regulates the process of this repression in a special way, namely in that the displacement is carried out with a known two-stage punch is, the gradation .invention is chosen so that the cross-section of the first stage smaller and that of the second stage larger than the tongue hole is.
Auf der Zeichnung sind Ausführungsbeispiele dargestellt, in Fig. leine Zungennadel in Ansicht, Fig. 2, 3 und 4 eine Nadel nebst Zunge in drei Hauptstadien der Herstellung des Zungendrehzapfens, Fig. 5 die beiden Preßstempel.In the drawing, exemplary embodiments are shown, in Fig. Leine Latch needle in view, FIGS. 2, 3 and 4 show a needle and tongue in three main stages the manufacture of the tongue pivot pin, Fig. 5 the two press rams.
Das Verdrängen des Werkstoffes in. die Zungenbohrung mit der oben angegebenen vorteilhaften Folge wird mittels der in Fig. 5 dargestellten beiden Preßstempel 1 4. ausgeführt.The displacement of the material in. The tongue hole with the above indicated advantageous consequence is by means of the two shown in FIG Press ram 1 4th executed.
Die beiden Preßstempel14 sind zweistufig. Sie endigen je in einen Dorn 15, dessen Querschnitt kleiner ist als.die Bohrung 3 der Zunge i. Der Dorn 15 sitzt auf einer konvexen Preßfläche 16, deren Querschnitt größer ist als die Zungenbohrung 3.The two press rams14 are two-stage. They each end in a mandrel 15, the cross section of which is smaller than.die hole 3 of the tongue i. The mandrel 15 sits on a convex pressing surface 16, the cross section of which is larger than the tongue bore 3.
Die Preßstempel 14 werden -' mit ihren Dornen 15 von außen beiderseits an die Wangen der Nadel 2 in der Höhe, in der sich die Bohrung 3 der im Nadelschlitz an iluen Platz ebrachten Zunge i befindet, angesetzt. Bei Beginn der durch die zueinander hin vordriügenden Stempel 14 auf die -Tadel ausgeübten Pressung verdrängen die Dorne 15 an den Stellen 6 und 7 Metall der Nade12 in die Zungenbohrung 3. Alsdann setzen sich die Stempel mit ihren konvexen Schultern 16 auf die die Eindrückungen umgebenden Stellen der Nadelwangen und schieben diejenigen Mengen des von. den Dornren verdrängten M etalles, die nach außen entweichen wollen, zur Seite, so daß die Entstehung einer Ringwulst an jenen NadelwangenstdIen unterbleibt und -ferner auch eine übermäßige lilemmung der Zunge i -in Richtung ihrer Drehachse vermieden wird.The ram 14 are - 'with their thorns 15 from the outside on both sides on the cheeks of the needle 2 at the level at which the bore 3 of the needle slot is located in the new place of the tongue i is attached. At the beginning of the through to each other towards the pushing punch 14 on the -pin exerted pressure displace the mandrels 15 at points 6 and 7 metal of the needle12 in the tongue hole 3. Then put it the stamps with their convex shoulders 16 on those surrounding the indentations Make the needle cheeks and push those amounts of the from. displaced the thorn M etalles that want to escape to the outside, to the side, so that the emergence of a There is no ring bead on those needle cheek joints and there is also an excessive one Limitation of the tongue in the direction of its axis of rotation is avoided.
Auf diese Weise werden zwei Zapfen 4. und 5 gebildet, die das Zungenloch 3 vollständig ausfüllen 'und somit zusammen einen dicht an der Zunge i anliegenden Drehzapfen bilden.In this way two pegs 4 and 5 are formed, which form the tongue hole 3 fill in completely 'and thus together a tight fit on the tongue i Form trunnions.
