Description
verbinden, sind an den beiden Langsenden des Gestells auch Traversen 13 vorhanden, und zwar zwei Paare an jedem Ende, wobei zwischen den Balken jedes Paares nur ein relativ enger Durchlaßspalt für Schraubbolzen 14 vorhanden ist. Auf der Traverse 13 liegen die Endteile von durchgehenden Tragschienen 15 auf, die zusammen eine Tragvorrichtung für einen zu schneidenden HartschaumstoffblockB bilden. Diese Tragschienen 15 erstrecken sich parallel zu den Langsbalken 6,7 in Abständen voneinander, die aus noch zu erläuternden Gründen veränderbar sind, solange Muttern 16, die auf den die Tragschienen 15 durchsetzenden Schraubbolzen 14 angeordnet sind, nicht angezogen sind.connect, there are also traverses 13 on the two long ends of the frame, namely two pairs at each end, with only a relatively narrow passage gap for screw bolts 14 between the beams of each pair. On the traverse 13 are the end parts of continuous support rails 15 which together form a support device for a rigid foam block B to be cut. These support rails 15 extend parallel to the longitudinal beams 6, 7 at distances from one another, which can be changed for reasons to be explained, as long as nuts 16, which are arranged on the screw bolts 14 penetrating the support rails 15, are not tightened.
Mittels kurzen Winkeleisen stücken 17 ist auf den beiden Laufwerken 10 und 11 der sich unter den Tragschienen 15 hinweg erstreckende Querteil 18 a eines Schneidrahmens 18 befestigt. Die Seitenteile 18 b, 18 c erstrecken sich vertikal nach oben und sind durch den oberen Querteil 18 d miteinander verbunden. An dem Schneidrahmen 18 sind vertikal verlaufende Schneiddrähte 19 und horizontal verlaufende Schneiddrähte 20 angebracht; bei allen diesen Schneiddrähten 19 und 20 handelt es sich um gespannt gehaltene Drähte, die zu ihrer Erhitzung von elektrischem Strom durchflossen sind. Die Anbringung und Verbindung mit den elektrischen Zuleitungen ist wohlbekannt und braucht deshalb nicht beschrieben zu werden. Besonders weil e nach Bedarf der Abstand zwischen den vertikalen Schneiddrähten 19 verändert werden kann, müssen auch die Abstände zwischen den Tragschienen 15 entsprechend verändert werden können, was nach Lockerung der Muttern 16 auf den Schraubbolzen 14 ohne weiteres erfolgen kann.By means of short angle iron pieces 17, the transverse part 18 a of a cutting frame 18, which extends under the support rails 15, is attached to the two drives 10 and 11. The side parts 18 b, 18 c extend vertically upwards and are connected to one another by the upper transverse part 18 d. Vertically extending cutting wires 19 and horizontally extending cutting wires 20 are attached to the cutting frame 18; all of these cutting wires 19 and 20 are wires which are held taut and through which an electric current flows in order to heat them. The attachment and connection to the electrical leads is well known and therefore need not be described. Especially because the distance between the vertical cutting wires 19 can be changed as required, the distances between the support rails 15 must also be able to be changed accordingly, which can easily be done after loosening the nuts 16 on the screw bolts 14.
Bei den vier Ständern 2, 3, 4 und 5 ist je eine Fuhrungssäule vorgesehen; alle diese vier Fuhrungssaulen sind mit 21 bezeichnet und unten mittels Verbindungs^tücken 22 an den benachbarten Gestellständem befestigt. Auf jeder dieser Führungssäulen 21 ist ein Schlitten 23 verfahrbar; auf beiden Maschinengestellängsseiten sind an Konsolen der dort befindlichen Schlitten die Endteile eines steifen Tragers 24 bzw. 25 befestigt. An diesen Tragern 24, 25 sind das eine bzw. andere Ende von Schneiddrähten angebracht (ähnlich wie die Schneiddrähte 19, 20 am Schneidrahmen 18 angebracht sind), um sich straff gespannt quer über die Maschine hinweg zu erstrek- IJ; auch' diese Schneiddrähte 26 sind stromdurchflössen in den Arbeitsperioden, in denen sie wirksam τ «naeiinterteiluns durchzuführen. Da- ^äSÄid^« in beliebenveränderlichen Abständen voneinander an-Digen, veid Di Antriebsvornchtung zumThe four uprights 2, 3, 4 and 5 each have a guide column; All of these four guide pillars are denoted by 21 and attached at the bottom by means of connecting pieces 22 to the adjacent frame posts. A slide 23 can be moved on each of these guide columns 21; On both sides of the machine frame, the end parts of a rigid support 24 and 25 are attached to the consoles of the slides located there. One or the other end of cutting wires are attached to these supports 24, 25 (similar to how the cutting wires 19, 20 are attached to the cutting frame 18) in order to stretch across the machine in a taut manner ; These cutting wires 26 also have current flowing through them in the working periods in which they are effectively carried out.
