Description

Zum Bearbeiten der schmalen Kantenflächen fassonierter Teile, insbesondere zum Entfernen des Grates an gepreßten Gegenständen, wie z. B. an Besteckteilen, verwendet man schon Maschinen, bei denen entweder das Werkstück von Hand oder mittels einer Einspannvorrichtung in den Wirkungsbereich von Fräsern oder Schleifscheiben gebracht wird. Es sind auch Maschinen bekannt geworden, die die schmalen Kantenflächen unter Anwendung einer -Schablone selbsttätig bearbeiten. Es war jedoch infolge der Form und Anordnung der Werkzeuge bisher nicht möglich, auf diesen Maschinen schaif einschneidende, bis zu einem rechten Winkel zur Längsachse des Werkstücks stehende Konturen der schmalen Kanten selbsttätig herauszuarbeiten. Die feinen Konturen machten vielmehr ein zeitraubendes Nacharbeiten vonFor processing the narrow edge surfaces of shaped parts, especially for Removing the burr on pressed objects, such as. B. on cutlery used you already have machines in which the workpiece is either manually or by means of a Jig brought into the range of action of milling cutters or grinding wheels will. Machines have also become known which automatically cut the narrow edge surfaces using a template to edit. However, due to the shape and arrangement of the tools, it has not been before possible on these machines sharply cutting, up to a right angle to the Work out the contours of the narrow edges along the longitudinal axis of the workpiece automatically. The fine contours made rather time-consuming rework of

It is made possible by the fact that

as spitzwinklig profilierte Schneid- oder Schleifwerkzeuge, zwischen denen sich ein Schlitten mit dem aufgespannten Werkstück bewegt, beim Arbeiten in einem spitzen Winkel zur Längsachse des Werkstücks stehen und in Schwingarmen ruhen, deren Drehpunkte so weit seitlich herausgeschoben sind, daß sich der zum Verschieben des Schwingarmes erforderliche Hebelarm ergibt und daß die den Werkzeugen durch eine Schablone, die mit dem Werkstück in parallelen Ebenen gleichachsig übereinander angeordnet ist, erteilte seitliche Bewegung durch unter Federzug stehende Kopierscheiben oder Taster erfolgt. Die Fräs- oder Schleifwerkzeuge werden also infolge ihrer spitzwinkligen und seitlich schneidenden Form in Verbindung mit ihrer Schräglage auch scharf einschneidende, feine, bis zu einem rechten Winkel zur Längsachse des Werkstücks stehende Konturen der schmalen Kanten sauber und selbsttätig ausarbeiten, was bisher teure Nacharbeit erforderte. he cutting or grinding tools with acute-angled profiles, between which a slide with the clamped workpiece moves, when working at an acute angle to Stand longitudinal axis of the workpiece and rest in swing arms, the pivot points are pushed out so far laterally that the lever arm required to move the swing arm and that the Tools through a template that is coaxial with the workpiece in parallel planes is arranged one above the other, given lateral movement by means of a spring tension standing copy disks or buttons takes place. The milling or grinding tools are thus due to their acute-angled and laterally cutting shape in conjunction with their Inclination also sharp, fine, up to a right angle to the longitudinal axis Work out the contours of the workpiece on the narrow edges neatly and automatically, which previously required expensive rework.

Auf dem Maschinengestell 1 befindet sich ein zu bewegender Schlitten 2, der die Aufspannunterlage 3 für das Werkstück 4 trägt, das durch die Spannvorrichtung 5 auf seiner Unterlage festgehalten wird. Die Spannvorrichtung ist mit dem Schlitten 2 durch Säulen 6 und den Steg 7 verbunden, auf dem die Kopierschablone 8 befestigt ist.
