Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Der Vorschubregler für Schlittenkaltsägen nach vorliegender Erfindung unterscheidet sich von den bereits bekannten Reglern dadurch, daß der Vorschub bei Überlastung des Sägeblattes durch denselben in der Weise selbsttätig nachgibt, bei zu großer Beanspruchung teilweise ausschaltet und automatisch, nachdem sich das Sägeblatt freigeschnitten hat, wieder einrückt, daß die als Halbmutter ausgebildete und durchThe feed regulator for sledge cold saws according to the present invention differs of the already known controllers in that the feed rate when the saw blade is overloaded automatically gives way through the same, sometimes if the load is too great switches off and automatically engages again after the saw blade has cut itself free, that trained as a half-mother and through

ίο ein Gewicht gegen die Vorschubspindel gepreßte Mutter durch die Keilflächen des trapezförmigen Gewindes der Vorschubspindel mehr oder weniger abgedrückt wird. Der Vorschub regler ist auf beiliegender Zeichnung dargestellt.ίο a weight pressed against the feed screw Nut through the wedge surfaces of the trapezoidal thread of the feed screw more or less is pulled. The feed controller is shown in the accompanying drawing.

Fig. ι zeigt eine Kaltsäge mit dem eingebauten Regler,Fig. Ι shows a cold saw with the built-in controller,

Fig. 2 die Wirkungsweise des Vorschubreglers in einem vergrößerten Schnitt,2 shows the mode of operation of the feed regulator in an enlarged section,

Fig. 3 das Trapezgewinde in größerem Maßstäbe. 3 shows the trapezoidal thread on a larger scale.

Die im Sägeschlitten α (Fig. 1 und 2) gelagerte, mit Trapezgewinde b versehene Spindel c wird in bekannter Weise, beispielsweise durch ein Schneckengetriebe oder durch das in der Zeichnung angedeutete Klinkwerk d gedreht und zieht Schlitten α in Pfeilrichtung B durch zwangläufige Führung in der als Halbmutter ausgebildeten Spindelmutter e vorwärts. Bei Überlastung des Schlittens α wächst der achsiale Druck in Spindel c derart an, daß die entsprechende Seitenkraft in Richtung A vermöge der Keilflächen f des Trapezgewindes b (Fig. 3) die mit dem Gewichtshebel k verbundene Halbmutter β nach unten herausdrückt. Gleicht sich der Überdruck aus, so geht die Halbmutter e in ihre frühere Lage zurück.The in the saw carriage α (Fig. 1 and 2), provided with trapezoidal thread b spindle c is rotated in a known manner, for example by a worm gear or by the ratchet mechanism d indicated in the drawing and pulls carriage α in the direction of arrow B by positive guidance in the spindle nut e designed as a half nut forward. When the slide α is overloaded, the axial pressure in spindle c increases in such a way that the corresponding lateral force in direction A by virtue of the wedge surfaces f of the trapezoidal thread b (FIG. 3) pushes the half nut β connected to the weight lever k downward. If the overpressure is equalized, the half-nut e goes back to its previous position.

Wird der Widerstand jedoch noch größer, so wird der Vorschub teilweise eingestellt dadurch, daß die abgedrückte Halbmutter e auf der Trapezgewindefläche g (Fig. 1) gleitet, um nach Ablauf der Strecke h an der Schrägfläche i abzugleiten in die ursprüngliche Lage.However, if the resistance is even greater, the feed is partially adjusted by the fact that the pressed half nut e slides on the trapezoidal thread surface g (Fig. 1) in order to slide after the distance h on the inclined surface i into the original position.
