Description

Elektromagnetisches Schlagwerkzeug Die bekannten elektromagnetischen Schlagwerkzeuge werden durch Elektromagnete in Form von Solenoiden betätigt.Electromagnetic impact tool The well-known electromagnetic Striking tools are operated by electromagnets in the form of solenoids.

Die magnetische Anzugskraft von Elektromagneten mit hufeisenförmigen Kernen ist im Vergleich mit der von Solenoiden bei gleichem Stromverbrauch eine größere.The magnetic attraction of electromagnets with horseshoe-shaped Cores is one compared to that of solenoids with the same power consumption bigger.

Diese bekannte Tatsache liegt der im folgenden beschriebenen Erfindung zugrunde. In der Zeichnung ist ein gemäß dieser Erfindung erbauter Hammer dargestellt; es zeigt Abb. s eine Draufsicht auf das Innere des Hammers. Abb.2 zeigt einen Längsschnitt und Abb. 3 einen Querschnitt auf A-B.This known fact resides in the invention described below underlying. The drawing shows a hammer constructed in accordance with this invention; it shows Fig. s a plan view of the interior of the hammer. Fig.2 shows a longitudinal section and Fig. 3 is a cross-section on A-B.

In ein Gehäuse a, welches den Griff mit dem Kontakt trägt, ist ein Elektromagnet b mit hufeisenförmigem Kern eingebaut und mit dem Gehäuse fest verbunden.In a housing a, which carries the handle with the contact, is a Electromagnet b installed with a horseshoe-shaped core and firmly connected to the housing.

Diesem gegenüber befindet sich ein zweiter, ebenfalls mit hufeisenförmigem Kern versehener Elektromagnet c, welcher mit dem Läufer oder Hammer d fest verbunden ist und mit ihm hin und her geht.Opposite this is a second, also with a horseshoe-shaped one Electromagnet c with a core, which is firmly connected to the rotor or hammer d is and goes back and forth with him.

Sobald die Magnete durch den elektrischen Strom erregt werden, ziehen sie sich gegenseitig an; da aber nir der vordere beweglich ist, wird dieser nach dem festen Magneten hingezogen mit der Anzugskraft beider Magnete, wobei in der Schlagfeder e Energie entsprechend der Anzugskraft beider Magnete aufgespeichert wird. Haben sich die einander gegenüberstehenden ungleichnamigen Pole der Elektromagnete auf eine gewisse Entfernung, welche von der Remanenz der Eisenkerne bedingt ist, genähert, so wird der elektrische Strom in einem der Elektromagnete umgeschaltet, d. h. er wechselt seine Richtung. Sobald der elektrische Strom in einem Elektromagneten seine Richtung ändert, ändern auch die Eisenkerne dieses Magneten ihre Pole; es kommen gleichnamige Pole gegenüber zu stehen; diese stoßen sich ab, wodurch die Schlagfeder entlastet wird und nun den Läufer oder Hammer nach vorn schleudert mit der in ihr aufgespeicherten Energie, welche noch durch die abstoßende Kraft der gleichnamigen Pole verstärkt wird.As soon as the magnets are excited by the electric current, pull they look at each other; but since only the one in front is movable, this one moves behind attracted to the fixed magnet with the attraction force of both magnets, whereby in the Striker spring e Energy stored according to the attraction force of both magnets will. Have the opposing poles of the electromagnets of different names to a certain distance, which is due to the remanence of the iron cores, approached, the electric current is switched over in one of the electromagnets, d. H. he changes direction. As soon as the electric current in an electromagnet changes its direction, the iron cores of this magnet also change their poles; it come to stand opposite poles of the same name; these repel each other, whereby the The mainspring is relieved and the runner or hammer is now thrown forward with it the energy stored in it, which is still due to the repulsive force of the Pole of the same name is reinforced.

Kurz vor Beendigung dies Schlages wird der elektrische Strom in einem der Elektromagnete wieder umgeschaltet und der Läufer zu neuem Schlage zurückgezogen.Shortly before the end of this blow, the electric current turns into one the electromagnet switched again and the rotor withdrawn to a new stroke.
