PATENTAMT.PATENT OFFICE.
Es sind Rüttelformmaschinen bekannt, bei denen das den Hammer gegen den Formträger treibende Mittel von Anfang an mit voller Kraft auf ihn wirkt, indem der Hammer durch Preßluft abwärts bewegt wird, deren Wirkung erst aufgehoben wird, wenn die ihn aufwärts treibende Kraft ihre volle Größe erlangt hat.There are known vibratory molding machines in which the hammer against the mold carrier driving means acts on him from the beginning with full force by moving the hammer downwards by compressed air, whose Effect is only canceled when the force that drives it upwards reaches its full size Has.
Demgegenüber besteht die Erfindung darin,In contrast, the invention consists in
ίο daß zum Abwärtsbewegen des Hammers elektromagnetische Kraft, z. B. unter Benutzung eines Solenoides, dient. Auf diese Weise werden die Vorzüge der Rüttelformmaschinen der in Rede stehenden Art auch für solche, namentlich kleinere Betriebe, in denen die Erzeugung oder Herbeischaffung von Preßluft sich zu teuer gestalten würde, nutzbar gemacht. Ein weiterer Vorteil ergibt sich daraus, daß beim Einschalten des elektrischen Stromes der Elektromagnetismus gleich in seiner vollen Stärke wirkt, während der volle Druck der Preßluft oberhalb des Hammers sich erst einige Zeit nach Umschaltung des Steuerorganes einstellt.ίο that electromagnetic to move the hammer down Force, e.g. B. using a solenoid, is used. In this way, the benefits of the vibratory molding machines The type in question also applies to those, especially smaller businesses, in which the production or procuring compressed air would be too expensive, made usable. Another advantage results from the fact that when the electrical current is switched on the electromagnetism works in its full strength, while the full pressure of the Compressed air above the hammer is only released some time after the control unit has been switched over adjusts.
