Description
Die Erfindung betrifft einen Stehbolzen-Ein- -und -Auszieher mit einem exzentrisch gelagerten und mit einer Riffelung oder Kordierung versehenen Klenirnrad.The invention relates to a stud bolt puller and extractor with an eccentrically mounted helical gear provided with corrugation or cording.
Die bekannten Stehbolzen-Ein- und -Auszieher besitzen Klenirnräder, welche auf der ganzen Oberfläche ihres Umfanges mit ewer Riffielung oder Kordierung versehen sind. Das Herstellen einer solchen Riffelung oder Korcherung ist mit Umständen verbunden, weil die Verdrängung des Materials Schwierigkeiten macht.The well-known stud bolt pullers and extractors have helical gears, which on the whole surface of their circumference with ewer corrugation or cording are provided. The production of such a corrugation or corrugation is not easy connected because the displacement of the material causes difficulties.
Da die ganze Oberfläche des Umfanges des Klemmracles bisher mit der Riffelung oder Kordierting versehen war, gab es nicht genug Raum, um das wegzudrängende Material aufzunehmen. Die Klernraräder konnten daher mit keiner tiefen Riffelungoder Kordierung versehen werden; außerdem war der Zeitaufwand für die Anfertigung der Riffelungoder Kordierung erheblich.Since the entire surface of the circumference of the Klemmracles so far with the Was corrugated or corded, there was not enough room to push away what was Record material. The Klernrar wheels could therefore not have any deep corrugation or Be provided with cords; in addition, the time required to produce the Corrugation or cording significant.
Dieser Mangel wird erfindungsgiemäß dadurch beseitigt, daß, das geriffehe oder kordierte Klemmrad auf seinem Umfang eine oder mehrere Rillen aufweist, wodurch eine wesentlich bessere HersteHungsmöglIchkeit der Riffelung oder Kordiermg des Klemmrades gewährleistet ist.According to the invention, this deficiency is eliminated by the fact that the riffle or corded clamping wheel has one or more grooves on its circumference, whereby a much better production possibility of the corrugation or cording of the Clamping wheel is guaranteed.
Eine beispielsweise Ausführungsform dies Erfin,dungsgegenstandes ist in der Zeichnung dargestellt. Es zeigt Fig. i eine Seitenansicht des Stehbolzen-Ein- und -Ausziehers, zum Teil geschnitten, Fig. 2 eine Draufsicht auf das Klemmrad und Fig. 3 eine Seitenansicht des Klemmrades mit einer auf seinem kordierten Umfang angebrachten einzigen Rille.An example embodiment of this invention is shown in the drawing. 1 shows a side view of the stud bolt retractor and extractor, partly in section, FIG. 2 shows a plan view of the clamping wheel, and FIG. 3 shows a side view of the clamping wheel with a single groove made on its corded circumference.
Der Stehbolzen-Ein- und -Auszieher nach der Erfindung besteht wie die bisher bekannten Werkzeuge dieser Art aus dem gabelförrniWn Führungskörper i mit dem darin exzentrisch gelagerten, Klemmrad. 3. Letzteres wird mittels einer versenkten Kopfschraube 2 in der Gabel des Führungskörpers i gehalten. Zwecks Erfassens der Vorrichtung beim Ausziehen des zu lösenden Bolzens mittels Schraubenschlüssels trägt der Führungskörper i einen sechskantigen Ansatz 5. Das in der Bohrung 2' exzentrisch im Führungskörper i gelagerte Klemmrad3 ist auf seinem kordierten Um- fang mit einer Rille 4 versehen, wodurchein wesentlich besseres Herstellen das Klemmrades möglich ist.The stud bolt puller and puller according to the invention, like the previously known tools of this type, consists of the fork-shaped guide body i with the clamping wheel eccentrically mounted therein. 3. The latter is held in the fork of the guide body i by means of a countersunk head screw 2. For the purpose of detecting the device when pulling out the to be solved bolt by means of the wrench of the guide body carries i a hexagonal neck 5. in the bore 2 'eccentrically in the guide body i stored Klemmrad3 is caught on its knurled environmental provided with a groove 4, whereby a much better preparing the clamping wheel is possible.
Statt einer einzigen Rille können mehrere Rillen auf dem Umfang das Klemmrades angebracht sein, wodurch sich die Verhältnisse bezüglich des zu verdrängenden Materials bei dem Herstellen der Kordierung günstiger gestalten.Instead of a single groove, several grooves can be made on the circumference of the clamping wheel, which makes the conditions with regard to the material to be displaced in the production of the cord more favorable.
Die neue Gestaltung des kordierten Klemmrades mit Rille ermöglicht ein sch-neHeres Herstellen der Kordlerung. Die aufzuwendende Zeit für das Herstellen der mit Rille versiehenen Klemmräder gegenüber der früheren Art ohne Rille verhält sich nach den vorgenommenen Versuchen wie 4: 1.The new design of the corded pinch wheel with groove makes it possible a beautiful production of cords. The time to spend in manufacturing the grooved pinch wheels compared to the earlier type without a groove after the attempts made, it turns out to be 4: 1.
