Description
Die Stumpfstoßschweißung der Schienen setzt einen nach allen Seiten genau winkelig geschnittenen Stoß von glatter und ebener Schnittfläche voraus, der nur mit einer sicher, teilweise als Fräser arbeitenden Kreissäge auszuführen ist. Dieses war bisher nur auf schweren, ortsfesten Maschinen in der Werkstatt oder auf schweren, fahrbaren Maschinen möglich, bei denen die zu schneidende SchieneThe butt joint welding of the rails sets you at an exact angle on all sides cut joint of smooth and even cutting surface, which can only be achieved with a is partially designed as a milling cutter working circular saw. This was only open so far heavy, stationary machines in the workshop or on heavy, mobile machines possible where the rail to be cut

IS schinen mit hin und her gehendem dünnen Sägenblatt gemacht. Hierbei konnte das Aufspannen der Maschine, das unbedingt nach zwei Seiten winkelig geschehen mußte, nur durch einen eingelernten Arbeiter zeitraubend gemacht werden, wobei sich dann noch der Nachteil ergab, daß der Schnitt durch das leicht bewegliche dünne Sägenblatt mit schmaler Führung leicht uneben wurde und nicht so zum Schweißen geeignet war, wie ihn eine kräftige Kreissäge liefert, die auf der ganzen Schnittlänge geführt wird.IS machines are made with a thin saw blade moving back and forth. Here the stretching could the machine, which absolutely had to be angled on two sides, only time consuming by a trained worker can be made, with the disadvantage that the cut through the Easily movable thin saw blade with a narrow guide was slightly uneven and not as suitable for welding as a powerful circular saw delivers, all over the place Cutting length is guided.
Die im Bahnkörper eingebaute Schiene zum Schweißen mit einer kräftigen, tragbaren Kreissäge zu schneiden, die der jeweiligen Lage der eingebauten Schiene angepaßt werden kann und sich beim Aufspannen selbst- j tätig, ohne zu messen, nach beiden Seiten winkelig einstellt, ist ein Bedürfnis im Bahnbau, ganz besonders im Straßenbahnbau geworden, wobei die hohen Pflasterkosten gespart werden und der Straßenverkehr weniger gestört wird. Diesem Bedürfnis soll die Er-. findung Rechnung tragen.The rail built into the track body for welding with a powerful, portable one To cut circular saw, which are adapted to the respective position of the built-in rail can and act independently when clamping, without measuring, to both sides at an angle has become a need in railway construction, especially in tram construction, whereby the high paving costs are saved and the road traffic is less disturbed. The er-. finding into account.
Dies geschieht dadurch, daß bei einer tragbaren Kreissäge mit geneigtem Sägeschlitten die Schlittenführungen und die Schienenauflageflächen einen geschlossenen rechteckigen Rahmen bilden, der an der Wurzel der Schlittenführungen geknickt ist, wobei die auf den Seitenwangen des Rahmens angeordneten Gegenhalter, um je einen in den S ei ten wangen drehbaren wagerechten Zapfen in den Rahmen klappbar sind und umgeklappt die Schienenauflageflächen nicht überragen.This is done by using a portable circular saw with an inclined saw carriage the slide guides and the rail support surfaces form a closed rectangular Form frame, which is kinked at the root of the carriage guides, with the on the Side cheeks of the frame arranged counterholder, around one in each side cheeks rotatable horizontal pins can be folded into the frame and folded down the rail support surfaces not tower above.
Die Schlittenführungen und die Spannflächen der Maschine bestehen aus einem geschlossenen rechteckigen Rahmen in leichter Bauart, der an der Wurzel der Schlittenführungen geknickt ist, wodurch eine starre Schlittenführung und ein leichtes, tragbares Gewicht gegeben ist. Durch die Knickung kann ein Kreissägenblatt vom kleinsten Durchmesser gewählt werden, da das Sägenblatt als Werkzeug gleichzeitig an Schienenkopf und Schienenfuß angreift.The slide guides and the clamping surfaces of the machine consist of a closed one rectangular frame of light construction, which is at the root of the slide guides is kinked, whereby a rigid slide guide and a light, portable weight is given. By the kink a circular saw blade with the smallest diameter can be selected as the saw blade acts as a tool on the rail head and rail foot at the same time.
