Description

Die Erfindung bezieht sich auf einen Gegenschlaghammer, bei dem in bekannter Weise die Bewegung des einen Bären die des anderen in gegenläufigem Sinn auslöst. Die meisten bisher gebräuchlichen Gegenschlaghämmer sind lufthydraulisch betriebene. Da@-neben kennt man auch elektromotorisch angetriebene. Bei diesen erfolgt der Antrieb des ,einen Bären über zwischen diesen und dem Motor vorgesehene Rad- oder Seilgetriebe. In Anlehnung an die, Art des Antriebs der bekannten Spindelpressen wird erfindungsgemäß vorgeschlagen, den einen der Bären durch eine Spindel anzutreiben und dabei die im Querhauet des Hammerständers anzuordnende treibende Mutter als Rotor eines Elektromotors auszubilden, so daß der Motorrotor unmittelbar, d. h. unter Wegfall von Zwischentrieben über die Spindel den Bären hebt und senkt. Die Spindel wird zweckmäßig durch Gummiod. dgl. Puffer nach oben und unten nachgiebig in den Bären eingesetzt.The invention relates to a counter blow hammer in which in As is well known, the movement of one bear is opposite to that of the other triggers. Most of the counterblow hammers in use up to now are air-hydraulic operated. There are also known electric motors driven. This takes place the drive of the, a bear through provided between these and the motor or cable gears. Based on the, type of drive of the known screw presses it is proposed according to the invention to drive one of the bears by a spindle and at the same time the driving mother to be arranged in the crosscut of the hammer stand as To form the rotor of an electric motor, so that the motor rotor directly, d. H. The bear raises and lowers with the elimination of intermediate drives via the spindle. the Spindle is expedient by rubber iodine. Like. Buffer yieldable upwards and downwards used in the bear.

In der Abbildung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt. In dieser ist mit i das Hammergestell und mit 2 und 3 die beiden Bären bezeichnet. Ober- und Unterbär sind durch die tnit 4 bezeichneten Seilzüge in bekannter Weise miteinander verbunden. In den Oberbären 2 i-st die Spindel 5 eingesetzt, und zwar nachgiebig durch Gummipuffer 6. Im Querhaupt 7 des Hammerständers ist ein Elektrotnotor untergebracht, dessen Rotor 8 mit der die Spindel 5 umfassenden 'Mutter g ein Ganzes bildet.In the figure, an embodiment of the invention is schematically shown. In this with i is the hammer frame and with 2 and 3 the two bears designated. The upper and lower rams are known by the cables indicated at 4 Way connected. The spindle 5 is inserted into the upper bear 2, and although yielding by rubber buffers 6. In the crosshead 7 of the hammer stand is an electric motor housed, the rotor 8 with the spindle 5 comprehensive 'mother g a whole forms.

Die Betriebsweise des neuen Hammers ist ohne weiteres verständlich; sie gestaltet sich so, daß durch Drehen des Rotors 8 in dem einen oder anderen Sinn die Spindel 5 axial nach oben oder nach unten bewegt wird. Das hat gleichzeitig ein Gegeneinanderbewegen der beiden Bären 2 und 3 zur Folge.The operation of the new hammer is easy to understand; it is designed so that by turning the rotor 8 in one sense or the other the spindle 5 is moved axially upwards or downwards. That has at the same time the two bears 2 and 3 move towards each other.
