Description
F i g. 1 ein Schaltbild undF i g. 1 a circuit diagram and
Fig.2 den Längsschnitt eines tragbaren elektrimagnetischen Naglers.Fig.2 shows the longitudinal section of a portable electromagnetic Naglers.
Nach dem Schaltbild der F i g. 1 ist die Arbeitswicklung 11 eines elektromagnetischen Naglers mit ihrem einen Ende über eine Leitung 12 an den festen Kontakt 13 eines Umschalters 14 angeschlossen, dessen Gegenkontakt IS über eine Diode 16 und einen Ohmschen Widerstand 17 sowie eine Leitung 18 an einem Pol 19 eines einphasigen Wechselstromnetzes 20 liegt. Das andere Ende der Arbeitswicklung 11 ist mit dem anderen Pol 21 des Wechselstromnetzes 20 über eine Leitung 22 verbunden, an der auch der negative1 Pol eines Kondensators 23 angeschlossen ist, dessen positiver Pol an den Mittelkontakt 24 des Umschalters 14 angeschlossen ist. Parallel zum Kondensator 23 liegt ein Löschwiderstand 25, der den Kondensator 23 entlad, wenn er vom Netz 20 getrennt ist.According to the circuit diagram of FIG. 1, one end of the working winding 11 of an electromagnetic nailer is connected via a line 12 to the fixed contact 13 of a changeover switch 14, its counter contact IS via a diode 16 and an ohmic resistor 17 and a line 18 to a pole 19 of a single-phase alternating current network 20 lies. The other end of the working winding 11 is connected to the other pole 21 of the alternating current network 20 via a line 22 to which the negative 1 pole of a capacitor 23 is also connected, the positive pole of which is connected to the center contact 24 of the changeover switch 14. A quenching resistor 25, which discharges the capacitor 23 when it is disconnected from the network 20, is located parallel to the capacitor 23.
Die bauliche Ausgestaltung des elektromagnetischen Naglers zeigt F i g. 2 in einer beispielsweisen Ausführungsform. Die Arbeitswicklung 11 ist von einem vorzugsweise aus Kunststoff bestehenden Naglergehäuse 26 umschlossen, das mit einem hohlen Handgriff 27 versehen ist. In dem Handgriff 27 sind der Umschalter 14 mit seinen Kontakten 13,15 und 24 und die Diode 16, sowie die Leitungen 12, 18,22 und eine Erdungsleitung 28 untergebracht. Diese Leitungen sind zu einem Kabel 29 zusammengefaßt und führen zu einem Stecker 30, der zum Anschluß an die beiden Pole 19 und 21 eines Wechselstromnetzes 20 dient und den Kondensator 23, den Ladungswiderstand 17 und den Löschwiderstand 25 entlad.The structural design of the electromagnetic nailer is shown in FIG. 2 in one example Embodiment. The work winding 11 is of a preferably made of plastic Enclosed nailer housing 26 which is provided with a hollow handle 27. In the handle 27 are the changeover switch 14 with its contacts 13, 15 and 24 and the diode 16, as well as the lines 12, 18,22 and a grounding line 28 housed. These lines are combined to form a cable 29 and lead to a plug 30, which is for connection to the two poles 19 and 21 of a AC network 20 is used and the capacitor 23, the charge resistor 17 and the quenching resistor 25 unload.
Die Arbeitswicklung 11 umschließt einen Tauchanker 31, der über einen Stift 32 in kraftübertragender Verbindung mit einem einarmigen Hebel 33 steht. Dieser ist an seinem hinteren Ende auf einer Achse 34 des Naglergehäuses 26 schwenkbar gelagert. Das vordere Ende des Hebels 33 ragt über die Stirnfläche des Naglergehäuses 26 und ist gelenkig mit einemThe working winding 11 encloses a plunger 31, which is in a force-transmitting manner via a pin 32 Connection with a one-armed lever 33 is available. This is at its rear end on an axis 34 of the nailer housing 26 is pivotably mounted. The front end of the lever 33 protrudes over the end face of the nailer housing 26 and is articulated with a
ίο Eintreibstößel 35 gekuppelt, der beim Arbeitshub des Naglers einen Nagel oder eine Klammer aus einem Magazin 36 in ein Werkstück treibt. Der Hebel 33 wird durch eine Torsionsfeder 37 in seiner in der Zeichnung gezeigten Anfangsstellung gehalten.ίο driving ram 35 coupled, which during the working stroke of the Nagler drives a nail or staple from a magazine 36 into a workpiece. The lever 33 is held in its initial position shown in the drawing by a torsion spring 37.
Der Umschalter 14 wird durch einen Fingerhebel 38 betätigt, der über ein federndes Zwischenglied 39 den Mittelkontakt 24 des Umschalters 14 aus der in der Zeichnung veranschaulichten Ruhelage so weit nach oben verschwenkt, bis die Kontakte 24 und 13The changeover switch 14 is actuated by a finger lever 38 which, via a resilient intermediate member 39 the center contact 24 of the switch 14 from the rest position illustrated in the drawing so far pivoted upwards until the contacts 24 and 13
ao geschlossen sind, wodurch der Kondensator 23 vom Netz getrennt und über die Arbeitswicklung 11 entladen wird. Durch den hierbei auftretenden starken Stromstoß zieht die Arbeitswicklung 11 den Anker 31 schlagartig an, wodurch der Hebel 33 den Eintreibstößel 35 nach unten bewegt und ein Nagel oder eine Klammer aus dem Magazin 36 in das Werkstück eingetrieben wird, was mit großer Kraft erfolgt, so daß auch große und lange Nägel und Klammern mit einem einzigen Schlag eingeschlagen werden.ao are closed, whereby the capacitor 23 is disconnected from the mains and discharged via the working winding 11 will. The working winding 11 pulls the armature as a result of the strong current surge that occurs here 31 abruptly, whereby the lever 33 moves the driving ram 35 down and a nail or a clamp from the magazine 36 is driven into the workpiece, which is done with great force, so that even large and long nails and staples can be driven in with a single blow.
Bei stationären Naglern können der Kondensator 23 und die beiden Widerstände 17 und 25 innerhalb des Naglergehäuses untergebracht sein.In the case of stationary nailers, the capacitor 23 and the two resistors 17 and 25 can be within of the nailer housing.
