Das Problem bei pneumatischen Klopfern besteht darin, den Kolben mit einer hohen Geschwindigkeit auf die Grundplatte auftreffen zu lassen. Dies wird bei bekannten pneumatischen Klopfern durch große Druckluft-Zuleitungen und Ventile erreicht .The problem with pneumatic knockers is that the piston hits the base plate at a high speed to hit. In known pneumatic knockers, this is achieved by means of large compressed air supply lines and valves .

Die Erfindung betrifft einen pneumatischen Klopfer, der sich j dadurch auszeichnet, daß er eine sehr hohe Schlagenergie bei geringem technischen Aufwand und Gewicht aufweist.The invention relates to a pneumatic knocker that j characterized in that it has a very high impact energy with little technical effort and weight.

Dies wird dadurch erreicht, das der Kolben aus einem Permanentmagneten (1) mit Manschette (2) und Führungsring (3) besteht und der Magnet an dem Anker (4) vom Deckel (5) haftet bis der Druck über dem Kolben die Magnetkraft über*- winden kann. Löst sich dann der Kolben vom Anker, so wird der Kolben durch die gespeicherte Druckluft stark beschleunigt und schlägt dann auf den Schlagbolzen (6) von der Grundplatte (7) auf. Wird der pneumatische Klopfer über den Luftanschluß (8) in Deckel entlüftet, so wird der Kolben von der Feder (9) in die Ausgangsstellung zurückgedrückt. -This is achieved by making the piston from a permanent magnet (1) with sleeve (2) and guide ring (3) and the magnet on the armature (4) from the cover (5) remains until the pressure above the piston exceeds the magnetic force * - can wind. If the piston is then released from the armature, the piston is strongly accelerated by the stored compressed air and then strikes the firing pin (6) from the base plate (7). Will the pneumatic knocker over the air connection (8) in the cover is vented, the piston is pushed back into the starting position by the spring (9). -

Da nach dem Lösen des Magneten vom Anker ein höherer Druck nicht mehr erforderlich ist, kann mit der ausströmenden Luft aus der Entlastungsbohrung (lo) das Zuluftventil umgesteuert werden. Die gespeicherte Luft expandiert fast adiabat und der pneumatische Klopfer arbeitet so am wirtschaftlichsten. Since after loosening the magnet from the armature, a higher pressure is no longer required, the air supply valve can be reversed with the air flowing out of the relief bore (lo) will. The stored air expands almost adiabatically and the pneumatic knocker works most economically.

Die Schlagarbeit kann durch Belegen der Polflächen mit unmagnetischen Stoffen und durch Drosseln der Entluftungsbohrungen (11) im Zylinderrohr (12) verringert werden.The impact work can be done by covering the pole faces with non-magnetic Substances and by throttling the ventilation holes (11) in the cylinder tube (12) can be reduced.

Wird am Kolben eine Kolbenstange angebracht, die nach außen führt, so kann ein //erkzeug (z.B. Stanzwerkzeug) mit dem Klopfer betrieben werden,If a piston rod is attached to the piston, it faces outwards leads, a // tool (e.g. punching tool) can be used with the Knockers are operated,
