Description

Vorrichtung zur kontinuierlichen Herstellung von Schießpulvern und Treibsätzen Zusatz zum Patent 1 212 In der deutschen Patentschrift 1 048 212 ist eine Vorrichtung zur kontinuierlichen Herstellung von Schießpulvern und Treibsätzen beschrieben, bei dem in einer kombimerten Schneckenpressenvorrichtung, die vollkommen. abgeschlossen ist, Pulvermassen aus der Formgehungsschnecke austreten und anschließend hinter dem Mundstück dieser Formgebungsschnecke mittels einer Schneidevorrichtung das gepreßte Pulver in die für den speziellen Zweck gewünschte Form gebracht wird. Die Größe des zu pressenden Pulverstranges ist dabei maßgeblich bestimmt durch den Durchmesser der Schneckenspindel derFormgebungsschnecke. Wird als Formgebungsschnecke eine Doppelschneckenpresse verwendet, bei der der Spindeldurchmesser z. B. 70 mm beträgt, so wird ein Pulverstrang erhalten, der nur 50 mm Durchmesser besitzt.Device for the continuous production of gunpowder and Propellant charges addendum to patent 1 212 In the German patent 1 048 212 is a device for the continuous production of gunpowder and propellants described, in which in a combined screw press device that perfectly. is complete, powder masses emerge from the shaping screw and then behind the mouthpiece of this shaping screw by means of a cutting device the pressed powder is brought into the shape desired for the specific purpose. The size of the strand of powder to be pressed is largely determined by the Diameter of the screw spindle of the shaping screw. Used as a shaping screw a twin screw press is used in which the spindle diameter z. B. 70 mm is, a strand of powder is obtained which is only 50 mm in diameter.

Efflndungsgemäß wird nun eine Vorrichtung vorgeschlagen, bei der man größere Pulverstränge pressen kann, ohne die Dimensionen der Spindelschnecke zu vergrößern. Man erhält z. B. bei Verwendung einer 70-mm-Spindelschnecke Pulverstränge bis zu 100 mm und mehr, wenn das Düsenwerkzeng zu einem Zylinder erweitert und verlängert wird und am Austritt der Düse eine Bremsplatte eingesetzt ist, die mit Radialschlitzen versehen ist. Diese Schlitze lassen die den Pulverstrang umgebende Luft beim Anfüllen der Düse entweichen, wobei man noch kurze Zeit auch Pulvermassen austreten läßt. Hierdurch bleibt die Pulvermasse im Fließen, und man erhält einen formgerechten und lunkerfreien Pulverkörper. According to the invention, a device is now proposed in which you can press larger powder strands without the dimensions of the screw screw to enlarge. One obtains z. B. Powder strands when using a 70 mm spindle screw up to 100 mm and more if the nozzle tool expands and extends into a cylinder and a brake plate with radial slots is used at the outlet of the nozzle is provided. These slots let the air surrounding the powder strand during the filling process escape the nozzle, and powder masses are also allowed to emerge for a short time. As a result, the powder mass keeps flowing, and you get a shape that is right in shape and void-free powder bodies.

Bei kontinuierlicher Verarbeitung und Herstellung längerer Pulverkörper wird die Bremsplatte abgenommen und somit ein der größeren Düsenöffnung entsprechender lunkerfreier Strang weiter ausgepreßt, da die Wandreibung den nötigen Widerstand zur Füllung der Düse bewirkt.With continuous processing and production of longer powder bodies the brake plate is removed and thus one that corresponds to the larger nozzle opening void-free strand pressed out further, since the wall friction provides the necessary resistance to fill the nozzle.

Fig. 1 zeigt eine Ausführung der erfindungsgemäßen Vorrichtung. Von der Formgebungssclinecke 1 gelangt die Pulvermasse in die erweiterte und verlängerte Düse 2. Zur Beheizung dieser Düse 2 ist diese mit einem Heißwassermantel 3 versehen. Am Düsenaustritt befindet sich die Bremsplatte 4 mit Nuten. Fig. 1 shows an embodiment of the device according to the invention. from the shaping screw corner 1, the powder mass reaches the expanded and lengthened Nozzle 2. To heat this nozzle 2, it is provided with a hot water jacket 3. The brake plate 4 with grooves is located at the nozzle outlet.

Fig. II zeigt die Bremsplatte 4 im Schnitt. Fig. II shows the brake plate 4 in section.
