F i g. 3 den Kastenabschnitt für den Stempel im Schnitt III-III nach F i g. 1 im vergrößerten Maßstab,F i g. 3 the box section for the stamp in section III-III according to F i g. 1 on an enlarged scale,

Fig.4 den Kastenabschnitt für den Stempel im Schnitt IV-IV nach F i g. 1 im vergrößerten Maßstab,4 shows the box section for the stamp in section IV-IV according to FIG. 1 on an enlarged scale,

F i g. 5 die Bremse für den Stempel im Ausschnitt V nach F i g. 1 im vergrößerten Maßstab.F i g. 5 the brake for the stamp in section V according to FIG. 1 on an enlarged scale.

Nach F i g. 1 bis 5 weist ein Zeichentisch einen Kasten 1 auf, in dessen säulenartigen Abschnitt 1 a Lagerböcke 2 vorgesehen sind, in denen mittels exzentrischer Zapfen 3 aus Kugellagern bestehende Führungsrollen 4 gelagert sind. Die Führungsrollen 4 (F i g. 3) dienen zur Führung eines aus Vierkantrohr hergestellten Stempels 5, dessen Querschnittsachsen zu denen des Kastens 1 bzw. des Säulenabschnitts 1 a um 45° versetzt angeordnet sind. Die Führungsrollen 4 greifen in zwei möglichst weit voneinander entfernten, zu der Achse des Stempels 5 senkrechten Ebenen, an dessen Außenflächen an, die im Bereich der Lauffläche für die Führungsrollen 4 mit einem flachen Belag 6 oder einem rechtwinkligen Belag 6' besetzt sind, wobei der Belag 6,6' aus einem verschleißfesten Werkstoff, wie Federstahl, besteht. In dem Stempels ist zumindest in dessen oben gelegenen Abschnitt eine kreiszylindrische Führungsbuchse 7 befestigt, in der ein kreiszylindrischer Stempeleinsatz 8 drehbar gelagert ist. Zum Feststellen des Stempeleinsatzes 8 ist eine Feststellbremse 9 vorgesehen, die aus einer in der Wand des Stempels 5 befestigten Bremsbuchse 10, einem darin axial verschiebbaren Bremskörper 11 und einem Bedienungshebel 12 besteht, der mit seinem Gewindelagerzapfen 12 a in einer Gewindebohrung der Bremsbuchse 10 derart gehalten und geführt ist, daß der Bremskörper 11 durch Schwenken des Bedienungshebels 12 an die Außenfläche des Stempeleinsatzes 8 angepreßt wird. An einem oben aus dem Stempels herausragenden Abschnitt des Stempeleinsatzes 8 ist einseitig ein waagerechter Ausleger 13 befestigt, an dem ein Zeichenbrettl4 mittels Träger 15, um die Achse des Auslegers 13 neigbar und mittels einer Neigungsbremse 16 feststellbar gehalten ist. An der Neigungsbremse 16 ist ein zweiarmiges Bedienungsorgan 17 vorgesehen, das zugleich über einen Bowdenzug 18 auf eineAccording to FIG. 1 to 5 comprises a sign table on a box 1, are provided in the column-like portion 1 a bearing brackets 2 are mounted in which, consisting of ball bearings by means of eccentric pin guide rollers 3. 4 The guide rollers 4 (F i g. 3) serve to guide a punch 5 made of a square tube, whose cross-sectional axes are arranged to be offset from those of the box 1 or the pillar portion 1 a by 45 °. The guide rollers 4 engage in two planes that are as far apart as possible and perpendicular to the axis of the stamp 5, on the outer surfaces of which are covered in the area of the running surface for the guide rollers 4 with a flat covering 6 or a right-angled covering 6 ' , the Cover 6,6 'made of a wear-resistant material such as spring steel. A circular-cylindrical guide bushing 7, in which a circular-cylindrical punch insert 8 is rotatably mounted, is fastened in the punch at least in its upper section. To lock the punch insert 8, a parking brake 9 is provided, which consists of a brake sleeve 10 fastened in the wall of the punch 5, a brake body 11 axially displaceable therein and an operating lever 12 which is held with its threaded bearing pin 12 a in a threaded hole in the brake sleeve 10 in this way and it is guided that the brake body 11 is pressed against the outer surface of the punch insert 8 by pivoting the operating lever 12. On one side of a section of the stamp insert 8 protruding from the top of the stamp, a horizontal bracket 13 is attached, on which a drawing board is held by means of a carrier 15, tiltable about the axis of the bracket 13 and lockable by means of a tilt brake 16. On the inclination brake 16, a two-armed operating member 17 is provided, which at the same time via a Bowden cable 18 on a

ίο Bremse 19 zum Feststellen des Stempels 5 in seiner jeweiligen Höheneinstellung wirkt. Die Bremse 19 (F i g. 5) besteht aus zwei, auf einem am unteren Ende des Stempels S festen Zapfen 20 schwenkbar gelagerten scherenartigen Hebeln 21a und 21b, einer in dem Säulenabschnitt 1 α festen, achsparallel zu dem Stempel 5 verlaufenden Bremsschiene 22 und einer Feder 23, durch die die an den Hebeln 21a und 21 b befestigten Bremsbacken 24a und IAb in Ruhestellung der Bremse 19 an die Bremsschiene 22 angelegt sind. Weiter sind an einer am unteren Ende des Stempels5 (Fig. 1) festen Nase 25 Zugseile 26 befestigt, die über Umlenkrollen 27 geführt, innerhalb des Kastenabschnitts Ib ein Gegengewicht 28 für den Stempels und alle darauf lastenden Teile, wie den Ausleger 13 und das Zeichenbrett 14, tragen. Die Höhen des Kastenabschnitts Ib ist gleich oder geringer bemessen als die lichte Höhe zwischen dem Fußboden und der Tischplatte t eines Arbeitstisches a. ίο Brake 19 acts to lock the punch 5 in its respective height setting. The brake 19 (F i g. 5) consists of two, at a fixed on the lower end of the plunger S pin 20 pivoted scissor-like levers 21a and 21b, a α in the column portion 1 fixed, axially parallel to the die 5 brake rail 22, and a spring 23 by which the b fixed to the levers 21 and 21 brake shoes 24a and IAb are applied in the rest position of the brake 19 to the brake rail 22nd Next, on a nose 25 fixed at the lower end of the punch 5 (Fig. 1), pull cords 26 are attached, which are guided over pulleys 27, within the box section Ib a counterweight 28 for the punch and all parts bearing on it, such as the boom 13 and the drawing board 14, wear. The height of the box section Ib is equal to or less than the clear height between the floor and the table top t of a work table a.

Während nach F i g. 1 das gemeinsame Bedienungsorgan 17 für die Neigungsbremse 16 und die Bremse 19 etwa knüppelartig ausgebildet ist, besteht nach F i g. 2 das Bedienungsorgan 29 aus einem Arm mit einem zunächst etwa vertikal gerichteten Abschnitt 29 a und einem anschließend etwa parallel zur Unterkante des Zeichenbrettes 14 verlaufenden Abschnitt 29 b, der als Griffleiste dient.While according to FIG. 1, the common control element 17 for the inclination brake 16 and the brake 19 is roughly designed like a stick, according to FIG. 2 the operating element 29 from an arm with an initially approximately vertically directed section 29 a and then a section 29 b which then runs approximately parallel to the lower edge of the drawing board 14 and which serves as a grip strip.
