Vorliegende Erfindung betrifft eine Vorrichtung . um die Walzen von Schraubenwalzmaschinen mit drei oder mehr Rädern oder Scheiben gegen einander zu bewegen.The present invention relates to an apparatus. around the rolls of screw rolling machines to move with three or more wheels or discs against each other.
Fig. ι zeigt die Stellung bei für die Einführung des zu walzenden Werkstückes aus einander bewegten bezw; geöffneten undFig. Ι shows the position for the introduction of the workpiece to be rolled moving from each other respectively; open and
Fig. 2 bei völlig geschlossenen Walzen.Fig. 2 with completely closed rollers.
Die Walzen abc sitzen auf beweglichen Wellen alblcl, welche in Lagerblöcken hhh angeordnet sind, auf deren äufsere Enden sich Hebel oder Stangen / auflegen. Die anderen Enden dieser Hebel/ greifen in einen beweglichen Ring d, durch dessen Arm e eine verstellbare Stange / führt. Letztere trägt eine Rolle g, welche durch eine Feder / oder Gewichtswirkung gegen ein Excenter j ständig angedrückt wird. Das Excenter erhält seinen Antrieb von einer Welle k. The rollers abc sit on movable shafts a l b l c l , which are arranged in bearing blocks hhh , on the outer ends of which levers or rods / rest. The other ends of these levers / engage in a movable ring d, through whose arm e an adjustable rod / passes. The latter carries a roller g, which is constantly pressed against an eccentric j by a spring / or weight action. The eccentric receives its drive from a shaft k.
Die Arbeitsweise der Vorrichtung ist folgende:The operation of the device is as follows:
Befindet sich die Rolle g in dem Ausschnitt / des Excenters j, so treten die Walzen abc weit aus einander und es kann das zu walzende Werkstück zwischen sie gebracht werden. Wird das Excenter j in Richtung des Pfeiles gedreht, bis die Walze g an dem Punkt 2 angelangt ist, so wird der Arm e nach aufsen gedrückt und bewegt den Ring d und die Stangen oder Hebel/ derart, dafs die Walzen abc zusammengeführt werden, das Werkstück erfassen und auf demselben in bekannter Weise durch Walzen das Gewinde erzeugen.If the roller g is in the cutout / of the eccentric j, the rollers abc come far apart and the workpiece to be rolled can be brought between them. If the eccentric j is rotated in the direction of the arrow until the roller g has reached point 2, the arm e is pressed outwards and moves the ring d and the rods or levers / in such a way that the rollers abc are brought together Detect workpiece and generate the thread on the same in a known manner by rolling.
Wenn der Theil 2, 3, 4 des Excenters einen Theil eines Kreises bildet, so erhält der Gewindetheil des Werkstückes durchweg gleichen Durchmesser und die Länge des hergestellten Gewindes hängt von der Drehungsgeschwindigkeit der Walzen, sowie von der Steigung des Gewindes auf denselben gegenüber der Geschwindigkeit des Excenters ab; denn sobald das Excenter eine volle Umdrehung ausgeführt hat, wird die Rolle g durch die Spannung, der Feder / in den Ausschnitt oder Abfall 1 des Excenters gezogen, wodurch die Walzen aus einander bewegt werden und das mit Gewinde versehene Werkstück herausfällt. Wenn der Theil 2, 3, 4 des Excenters, wie dargestellt, excentrisch ist, so werden die Walzen allmälig dichter zusammengedrückt und es wird so eine konische Schraube gewalzt. Durch Erhöhen oder Vermindern der Umlaufsgeschwindigkeit des Excenters kann die Konicität verändert werden.If the part 2, 3, 4 of the eccentric forms part of a circle, the thread part of the workpiece has the same diameter throughout and the length of the thread produced depends on the speed of rotation of the rollers, as well as on the pitch of the thread on them in relation to the speed of the Eccentric off; because as soon as the eccentric has performed a full revolution, the roller g is pulled by the tension, the spring / into the cutout or waste 1 of the eccentric, whereby the rollers are moved apart and the threaded workpiece falls out. If the part 2, 3, 4 of the eccentric, as shown, is eccentric, the rollers are gradually pressed closer together, and a conical screw is thus rolled. The taper can be changed by increasing or decreasing the speed of rotation of the eccentric.
