Gegengewic ht s-Stangenvo r se hübe sind bei "ierkzeugmasehinen, die St angenmater ial verarbe iten, insbesondere bei 'ievo lver drehbänken und Einsp inde 1—OrehautoEiat en bekannt.Sie werden dort insbesondere zum Vorschieben leichterer Materialstangen verwendet.Prinzipie11 wird dabei die waagerecht geführte I<ateri al stange nach dem Öffnen r*er Spannpatrone durch ein Gegengewicht in eine im wesentlichen gleichmäßig beschleunigte Bewegung versetzt,wöbei die Reibung in der ^pannpatrone,sowie im Führungsrohr bzw»im Führungslager zu überwinden ist.Counterweights bar front strokes are used in tool machines that Process general material, especially on 'ievo lver lathes and Einsp inde 1 — OrehautoEiat en. They are there in particular Used to advance lighter bars of material. Principle 11 the horizontally guided I <ateri al rod after opening r * er collet by a counterweight in an essentially evenly accelerated movement offset, where the friction in the fire cartridge, as well as in the guide tube or in the guide bearing is overcome.
Tiese ieibung ist ,lern augebl ickl ic hen Gewicht der Materialstange etwa proportional,d.h, sie ist umso geringer,je geringer das Gewicht des Stangen-Hest Stücks ist.Außerdem wird das leichtere ;le st stück der !--aterialst ange durch das Gegengewicht inehr beschleus* nigt als die anfänglich vorhanden gewesene volle Länge der Material stange. ")ie s hat zur Folge, daß zunächst die volle Länge der Materialstange sanft gegen den Anschlag der "Oreh-, b zw. Werkzeugmaschine vorgeschoben wird,und daß mit abnehmendem Gewicht bzw„abnehmender Länge der Water ial stange das Vorschieben ns it immer höherer Geschwindigkeit erfο Igt,wo bei der Anprall des Materials am Anschlagiinmer härter wird. Ties hat ferner ein Zurückfedern des immer leichter werdenden Stangenrestes zur Folge,d.h. es werden unnötig große '■Veriest ο ff zugaben er for der 1 ic h , wenn man die üblichen Längentoleranzen an den "/e rkstiicken einhalten will.This friction is approximately proportional to the learning of the weight of the material bar, that is, the lower the weight of the bar-hest piece, the lower it is. In addition, the lighter it becomes ; le st piece of the material rod is more accelerated by the counterweight than the initially available full length of the material rod. The result is that initially the full length of the material rod is gently advanced against the stop of the machine tool, and that with decreasing weight or decreasing length of the water rod, the advance ns it ever higher Speed is where it gets harder when the material hits the stop. Ties also cause the remainder of the rod, which is becoming lighter and lighter, to spring back, ie unnecessarily large amounts of tape are admitted if one wants to adhere to the usual length tolerances on the back pieces.
*)ie dargestellten Nachteile ergeben sich insbesondere an Waterial stangen größeren Gewichts,so daß sich die Gegengewichts-StangenvorSchübe bislang nur für leichtere Arbeiten einführen konnten.So verwendet man beispielsweise bei ^tangendurchmessern von etwa 40 mm "lure hne s ser bereits elektromotorische Antri ebe , z. B. über Orehnagnete mit nachgeschaltetem Unterset Zungsgetriebe?die das I- aterial nicht über eine bestimmte Geschwindigkeit hinaus beschleunigen können.*) The disadvantages shown arise in particular on material rods of greater weight, so that the counterweight rod feeders have so far only been able to be used for lighter work. z. B. over Orehnagnete with downstream subset Zung gear? can not speed over a certain speed, the I- aterial.
'Hese Lösung hat den Nachteil eines bedeutenden größeren Aufwandes gegenüber dem Gegengewichts-Stangenvorse hub , außerdem'Hese solution has the disadvantage of a significantly larger one Effort compared to the counterweight rod front hub, as well
