Description
Gegenstand der Erfindung ist eine verstellbare Führung für Stahlbandscheren. Diese Führungen bestehen aus zwei gegenüberliegenden Scheiben, welche auf das genaueste unabhängig zueinander einstellbar sind. Der Erfindung gemäß sind die Spindeln dieser Scheiben verschiebbar in Supporten gelagert und ihre durch Arme mit dem Support verschiebbar befestigten Schraubenmuttern werden durch Schraubenfedern nachgiebig gegen die Supporte gehalten.The invention relates to an adjustable guide for steel band scissors. These Guides consist of two opposing discs, which are very precise can be set independently of each other. According to the invention, the spindles of these disks are displaceable in supports stored and their nuts slidably attached to the support by arms are held resiliently against the supports by helical springs.

Das Stahlband wird durch die scherenartig arbeitenden Messer e, f zerschnitten, von denen das obere Messer e durch ein Exzenter, das auf der Welle b sitzt, auf und ab bewegt wird, sobald die Welle durch die Riemenscheibe d in Umdrehung versetzt und die Kupplung c eingerückt ist. Es kommt nun zwecks Erzielung eines geraden Schnittes auf eine genaue regelbare Führung des Stahlbandes an, und um diese zu erreichen, sind zwei Scheiben g und h seitlich auf dem Maschinengestell gelagert. Die Scheiben sind an den Enden von Schraubenspindeln 2, k befestigt, die in Supporten η, ο verschiebbar gelagert sind. Sie sind unabhängig voneinander durch Handrädchen /, m gegeneinander in Richtung ihrer Achsen verstellbar.The steel band is cut by the scissor-like knives e, f , of which the upper knife e is moved up and down by an eccentric located on the shaft b as soon as the shaft is set in rotation by the pulley d and the clutch c is indented. In order to achieve a straight cut, it is important to have an exact, controllable guidance of the steel strip, and in order to achieve this, two disks g and h are mounted on the side of the machine frame. The disks are attached to the ends of screw spindles 2, k , which are slidably mounted in supports η, ο. They can be adjusted independently of one another in the direction of their axes by means of handwheels /, m.
Auf diese Weise können die Führungsscheiben g und h entsprechend der Breite des Stahlbandes und in richtiger Lage zu den Messern eingestellt werden. Damit nun aber die Führung nicht starr ist, sind auf den Spindeln i, k Schraubenmuttern p, q angebracht, in denen der außen liegende Gewindeteil verschraubbar ist. Die Muttern sind durch Federn r, s mit den Supporten nachgiebig verbunden und bekommen ihren Halt und ihre Führung dadurch, daß sie an Armen t und % festsitzen, deren Stifte v, w in Schlitzen χ und y der Supporte η und 0 ihre Führung haben.In this way the guide disks g and h can be adjusted according to the width of the steel strip and in the correct position relative to the knives. So that the guide is not rigid now, however, screw nuts p, q are attached to the spindles i, k , in which the outer threaded part can be screwed. The nuts are flexibly connected to the supports by springs r, s and are held and guided by the fact that they are stuck on arms t and % , the pins v, w of which are guided in slots χ and y of the supports η and 0.
