Das Handrad 23 ist abnehmbar aufdem Halter 17 angeordnet, wobei der entsprechende Abschnitt des Halters 17 auch zylindrisch gestaltet und einen oder mehrere Vorsprünge (nicht dargestellt) aufweisen kann, die mit entsprechenden Ausnehmungen im Handrand 23 - mindestens in der Endposition des bis zum ringförmigen Anschlag 18 aufgeschobenen Handrades 23 - in Wirkverbindung treten kann bzw. können. Der äußere Teil des Halters 17 kann auch als Mehrkant-, z. B. Sechskantdorn (s. Fig. 3h) ausgestaltet sein, auf den das Handrad 23 mit einer entsprechend gestalteten zentralen Öffnung 24 (s. Fig. 3i) drehfest aufschiebbar ist. Der äußere Teil des Halters 17 weist eine über das aufgeschobene Handrad 23 herausragende Verlängerung 25 auf, die zum Ansatz eines Werkzeugs, z. B. einer Knarre oder eines Elektroschraubers gestaltet ist. Im Ausführungsbeispiel ist die Verlängerung 25 in Form eines Sechskants (s. die Öffnung 24 in Fig. 3i) ausgeführt.Axially and centrally within the screw cap 16 is axially movable Holder 17 arranged. The holder 17 (see Fig. 3h) has an annular Projection 18, which serves to support the screw cap 16. The part of the holder 17, which extends through the screw cap 16 into the housing 2 extends, is preferably cylindrical. There is one on him Pressure coil spring 19 placed on the one hand on the screw cap 16, pressing it against the annular projection 18 and on the other hand a support, e.g. B. supports a snap ring 20 which in one in the area of the free end of the cylindrical holder part arranged groove 21 can be used is. In the front end of the inner part of the holder 17 there is a recess 22 executed for non-rotatable engagement with the second end of the Driving pin 14 determined and the outline is adapted. The outer part the holder 17 has a section for receiving a handwheel 23. The handwheel 23 is removably mounted on the holder 17, the corresponding section of the holder 17 also cylindrical and one or can have several projections (not shown), which with corresponding recesses in the edge of the hand 23 - at least in the End position of the slide up to the annular stop 18 Handwheel 23 - can or can interact. The outer part the holder 17 can also as a polygonal, for. B. hexagon mandrel (see Fig. 3h) be designed, on which the handwheel 23 with a correspondingly designed central opening 24 (see FIG. 3i) can be pushed on in a rotationally fixed manner. The outer part of the Holder 17 has a protruding over the pushed-on handwheel 23 Extension 25 on the approach to a tool such. B. a ratchet or an electric screwdriver. In the exemplary embodiment, the Extension 25 in the form of a hexagon (see the opening 24 in Fig. 3i) executed.

Die Innenbohrung 28 der Endhülse 26 ist als Aufnahme eines Mehrkantsteckteils 29 mit Kopf 30 (Fig. 3a; in Fig. 3b im Querschnitt entlang Linie b - b in Fig. 3a dargestellt) angepaß. Der Mehrkantsteckteil 29 mit dem Kopf 30 weist eine axiale zentrale Durchgangsöffnung 31 auf, die zum Durchgang der Ziehschraube 12 mit Kopf 13 (Fig. 3f) dient und an ihre Abmessungen angepaßt ist sowie eine stirnseitige Anlagefläche 8 für eine Blindnietmutter.The inner bore 28 of the end sleeve 26 is a receptacle Polygonal plug-in part 29 with head 30 (Fig. 3a; in Fig. 3b in cross section Line b - b shown in Fig. 3a) adapted. The polygonal plug part 29 with the Head 30 has an axial central through opening 31, which for Passage of the drawing screw 12 with head 13 (Fig. 3f) serves and to her Dimensions is adapted and an end face 8 for one Blind rivet nut.

Das Innenlager kann auch aus einer oder mehreren Lagerscheiben 32 bestehen und ein Nadeldrucklager 33 (s. Fig. 3e) aufweisen, das dazu dient, die Reibung zwischen dem Gehäuse 2 und dem Kopf 13 der Ziehschraube 12 zu verringern, wenn die Ziehschraube 12 zum Setzen einer Blindnietmutter gedreht wird. Auch dieses Innenlager kann fest oder auswechselbar angeordnet sein.The bottom bracket can also consist of one or more bearing disks 32 and have a needle pressure bearing 33 (see FIG. 3e), which serves the Friction between the housing 2 and the head 13 of the pull screw 12 decrease if the pulling screw 12 for setting a blind rivet nut is rotated. This bottom bracket can also be fixed or replaceable be arranged.

Wenn Blindnietmuttern mit unterschiedlichen Gewindedurchmessern gesetzt werden sollen, müssen Ziehschrauben 12 mit entsprechendem Gewinde in das Setzwerkzeug 1 eingesetzt werden. Hierzu ist es sinnvoll, bzw. notwendig, auch die Durchgänge in den Innenlagern, d. h. im Stützring 11 bzw. im Nadeldrucklager 33 und den Lagerscheiben 32, als auch im Mehrkantsteckteil 29 mit Kopf 30 durch entsprechende Teile mit jeweils angepaßter Durchgangsöffnung auszuwechseln. Im Falle, daß die Innenlager fest und nicht auswechselbar angeordnet sind, müssen sie den Durchgang der Ziehschraube 12 mit größtem Gewindedurchmesser erlauben. Um ein eventuelles Durchrutschen der Köpfe 13 der Ziehschrauben 12 mit kleineren Gewindedurchmessern zu verhindern, werden jeweils an die Gewindedurchmesser angepaßte auswechselbare Reduzierscheiben (nicht dargestellt) eingesetzt.If blind rivet nuts are set with different thread diameters to be pull screws 12 with the appropriate thread in the Setting tool 1 are used. For this, it makes sense or is necessary also the passages in the bottom brackets, d. H. in the support ring 11 and Needle thrust bearing 33 and the bearing washers 32, as well as in the polygonal plug part 29 with head 30 by appropriate parts, each adapted Exchange through opening. In the event that the bottom bracket is fixed and are not arranged interchangeably, they must pass through the Allow pulling screw 12 with the largest thread diameter. To a possible slipping of the heads 13 of the pull screws 12 with smaller ones To prevent thread diameters are given to the Interchangeable reducers (not shown) used.

Das Auswechseln erfolgt auf die Weise, daß der Schraubdeckel 16 vom Gehäuse 2 abgeschraubt und mit dem Halter 17, der den Mitnehmerdorn 14 und das Handrad 23 trägt, aus dem Gehäuse 2 entfernt wird. Der Mitnehmerdorn 14 kann durch eine nicht dargestellte Schnappverbindung im Halter 17 gegen ein Herausfallen gesichert sein. Sodann wird auch die Ziehschraube 12 gegebenenfalls durch Druck aufihr aus dem vorderen Ende 3 des Gehäuses 2 herausragendes Ende entfernt, wobei auch - gegebenenfalls - das Innenlager, der Stützring 11, bzw. die Lagerscheiben 32 und gegebenenfalls das Nadeldrucklager 33 oder auch nur Teile davon entfernt werden, soweit sie überhaupt auswechselbar sind. Schließlich wird der Mehrkantsteckteil 29 aus der Endhülse 26 herausgezogen, wobei diese im Gehäuse 2 fixiert verbleibt. Die Außenmaße aller Mehrkantsteckteile 29 für alle Größen von Blindnietmuttern sind einander identisch, so daß die Endhülse 26 nicht ausgewechselt werden muß, wenn ein Mehrkantsteckteil 29 mit anderem Durchmesser der Durchgangsöffnung 31 benötigt wird.The replacement takes place in such a way that the screw cap 16 from Unscrewed housing 2 and with the holder 17, the drive pin 14th and carries the handwheel 23 is removed from the housing 2. Of the Driving pin 14 can by a snap connection, not shown in the Holder 17 be secured against falling out. Then the Pull screw 12 if necessary by pressing on it from the front end 3 of the housing 2 protruding end removed, also - if necessary - The bottom bracket, the support ring 11, or the bearing washers 32 and if necessary, the needle pressure bearing 33 or only parts of it removed as far as they are interchangeable at all. Finally the Polygonal plug 29 pulled out of the end sleeve 26, these in Housing 2 remains fixed. The external dimensions of all polygonal plug-in parts 29 for all sizes of blind rivet nuts are identical to each other, so that the End sleeve 26 does not have to be replaced when a polygonal plug 29 with a different diameter of the through opening 31 is required.

Es wird nunmehr die für die gewünschte Ziehschraube 12 angepaßte Schraubhülse 5, wie oben erwähnt, in das vordere Ende 3 des Gehäuses 2 eingeschraubt und mittels der Kontermutter 9 befestigt, bzw. es wird der Mehrkantsteckteil 29 mit der derjeweiligen Ziehschraube 12 entsprechenden Durchgangsöffnung 31 in die Endhülse 26 eingeführt. Dann wird jeweils das, gegebenenfalls ausgewechselte an den Durchmesser der neuen Ziehschraube 12 angepaßte, Innenlager in Form eines Stützrings 11, bzw. im Falle eines mehrteiligen Innenlagers die Lagerscheiben 32 mit dem Nadeldrucklager 33 an der Stufe 10 abgestützt angeordnet und gegebenenfalls festgelegt oder bei fest angeordnetem Innenlager wird eine angepaßte Reduzierscheibe auf die jeweilige Ziehschraube 12 aufgeschoben, wonach dann die jeweilige neue Ziehschraube 12 von der deckelseitigen Öffnung des Gehäuses 2 durch die Durchgänge im Innenlager bzw. Mundstück soweit eingeführt wird, bis sich ihr Kopf 13 bzw. die an ihm anliegende Reduzierscheibe am Innenlager abstützt. Dann wird der Halter 17 mit einem gegebenenfalls auch ausgewechseltem Mitnehmerdorn 14 bestückt, wobei dessen freies Ende zur drehfesten Verbindung in den Kopf 13 der Ziehschraube 12 eingeführt wird, wonach der Deckel 16 aufgeschraubt wird. Bei kleinen Blindnietmutterndurchmessern kann die Kraft zum Setzen der Blindnietmuttern mittels des Handrades 23 übertragen werden, das ansonsten auch zum Ausdrehen einer Ziehschraube 12 aus der gesetzten Blindnietmutter dient. Insbesondere bei großen Blindnietmuttern-durchmessern können die Kräfte zum Setzten mittels einer Knarre oder einem Schraubendreher äufgebracht werden, die an der Verlängerung 25 angesetzt werden.It will now be adjusted for the desired screw 12 Screw sleeve 5, as mentioned above, in the front end 3 of the housing 2nd screwed in and fastened by means of the lock nut 9, or it becomes the Polygonal plug-in part 29 with the corresponding pulling screw 12 Through opening 31 is inserted into the end sleeve 26. Then that if necessary, changed to the diameter of the new draw screw 12 adapted, bottom bracket in the form of a support ring 11, or in the case of a multi-part inner bearing, the bearing disks 32 with the needle pressure bearing 33 arranged supported at level 10 and optionally fixed or at fixed bottom bracket is a customized reducer on the respective pull screw 12 pushed, after which the respective new one Pull screw 12 from the cover-side opening of the housing 2 through the Passages in the bottom bracket or mouthpiece are inserted until there is her head 13 or the reducer attached to it on the bottom bracket supports. Then the holder 17 with a possibly also replaced driving mandrel 14, the free end of which non-rotatable connection is inserted into the head 13 of the pull screw 12, after which the lid 16 is screwed on. With small blind rivet nut diameters can the force for setting the blind rivet nuts by means of the Handwheel 23 are transmitted, which otherwise also for turning one Pull screw 12 from the blind rivet nut used. Especially at Large blind rivet nut diameters can set the forces be brought up by means of a ratchet or a screwdriver the extension 25 are scheduled.

Je nach den aufzubringenden Kräften können beispielsweise Innenlager mit gleichem Durchgangsdurchmesser für mehrere Größen von Ziehschrauben 12 eingesetzt werden, was die zu wechselnden Teile vermindert, wobei ein ausreichender Kontakt zwischen Stufe 10 und Stützring 11, bzw. Lagerscheibe 32 einerseits und diesen Teilen mit dem Kopf 13 der Ziehschraube 12 andererseits gewährleistet sein muß. Es kann auch vorteilhaft sein, das Innenlager ganz, oder im Falle eines mehrteiligen Innenlagers mindestens Teile davon, aufderjeweiligen Ziehschraube 12 anzuordnen und festzulegen oder einstückig herzustellen, was deren Verlust als relativ kleines Einzelteil verhindert.Depending on the forces to be applied, bottom brackets can also be used same passage diameter for several sizes of drawing screws 12 are used, which reduces the parts to be changed, a sufficient contact between step 10 and support ring 11, or Bearing plate 32 on the one hand and these parts with the head 13 of the Draw screw 12 must be ensured on the other hand. It can also be advantageous, the bottom bracket entirely, or in the case of a multi-part Bottom bracket at least parts thereof, on the respective pull screw 12 to arrange and fix or manufacture in one piece what their loss prevented as a relatively small item.
