Description

Die Erfindung betrifft eine Bügelsäge mit bogenförmiger Schnittbahn und besteht darin, daß der Bogensehnitt durch Aufhängung des Sägebügels an einem pendelnden Kurbelvdereck erzeugt wird, das den Zapfen trägt, um den der Bügel heb- und !senkbar ist. Eine besonders genaue Führung des Bügels wird dadurch erreicht und jedes Verkanten oder Ecken vermieden, daß zwei miteinander verbundene pendelnde Kurbelvierecke vorgesehen sind, die den sie querverbindenden Drehzapfen für den Sägebügel tragen. Der an diesem Drehzapfen angreifende Antrieb wirkt in diesem Falle genau in der Ebene des Bügels, so daß seitliche Kräfte nicht auftreten können.The invention relates to a hacksaw with an arcuate cutting path and consists in that the bow cut by hanging the saw bow on a pendulum crank is generated, which carries the pin around which the bracket can be raised and lowered. One particularly precise guidance of the bracket is achieved and any tilting or Avoid corners that two interconnected oscillating crank quadrilaterals are provided that they carry the cross-connecting pivot for the saw bow. The one on this one The drive engaging the pivot acts in this case exactly in the plane of the bracket, so that lateral forces cannot occur.

Der Sägebügel ι ist um den Zapfen 2 heb- und senkbar und wird mittels der an letzterem angreifenden Stange 3 vom Antrieb der Maschine aus mittels Kurbelschwinge langsam vor und rasch zurück bewegt. Der beabsichtigte Bogenschnitt kommt dadurch zustande, daß der Zapfen 2 pendelnd in einem Kurbelviereck 4, 5, 6 gelagert ist, das in Augen 7, 8 des Maschinengestells 9 angelenkt und von der Antriebsstange 3 derart hin- und herge-Schwüngen wird, daß der Zapfen 2 den in Abb. ι dargestellten Kreisbogen 10 beschreibt. Um ein Ecken der Bügelaufhängung und der Säge zu vermeiden, werden vorteilhaft zwei Kurbelvierecke 4, 5, 6 nebeneinander vorgesehen, zwischen denen der Sägebügel 1 liegt.The saw bow ι can be raised and lowered around the pin 2 and is attached to the latter by means of the attacking rod 3 from the drive of the machine by means of a crank arm slowly Moved back and forth quickly. The intended arch cut is achieved by that the pin 2 is mounted oscillating in a crank square 4, 5, 6, which in eyes 7, 8 of the machine frame 9 and swings back and forth from the drive rod 3 in this way is that the pin 2 describes the arc 10 shown in Fig. ι. In order to avoid corners of the bracket suspension and the saw, two are advantageous Crank squares 4, 5, 6 are provided next to one another, between which the saw bow 1 is located.
