Nut aus gewalztem Metall.Rolled metal groove.

Patentiert im Deutschen Reiche vom 24. November 1905 ab.Patented in the German Empire on November 24, 1905.

Es ist bekannt, Schlägerplatten an der Dreschmaschinentrommel durch Schraubenbolzen zu befestigen, welche ganz durch die Platte hindurchgehen. Diese Anordnung ergibt jedoch eine unsichere Verbindung, und die Schrauben-■ köpfe müssen der äußeren Fläche der Schlägerplatten entsprechend ausgebildet werden. It is known to attach racket plates to the threshing machine drum by screw bolts which go right through the plate. However, this arrangement results an unsafe connection, and the screw heads must be ■ designed to match the outer surface of the club plates.

Es sind auch Schlägerplatten bekannt, welche auf ihrer ganzen Länge mit einer durchgehendenThere are also racket plates known, which over their entire length with a continuous

ίο Nut oder einem schwalbenschwanzförmigen Einschnitt versehen sind, in welche Köpfe von Befestigungsbolzen eingreifen, um die Schlägerplatten an der Trommel zu befestigen. Bei dieser Anordnung konnte bisher die Nut in der unteren Platte nur dadurch hergestellt werden, daß die Schlägerplatte entweder gegossen wurde oder dadurch, daß die Schlägerplatte zunächst zu der gewünschten Form ausgewalzt und daß. die Nut dann in sie eingeschnitten wurde.ίο groove or a dovetail shape Incisions are provided in which heads of fastening bolts engage to secure the club plates to the drum. at this arrangement could previously only produce the groove in the lower plate that the racket plate has either been cast or by first rolling the racket plate into the desired shape and that. the groove was then cut into it.

Nach vorliegender Erfindung sollen Schlägerplatten für Dreschmaschinen mit unterschnittener Nut fertig gewalzt werden, ohne daß es notwendig ist, die Nuten in das Metall nachträglich einzuschneiden. Es wird dies dadurch erreicht, daß zunächst mittels eines an sich bekannten Walzverfahrens eine Platte mit einer offenen Nut und seitlichen Längsrippen an der einen Seite, sowie querliegenden Schlägerrippen an der anderen Seite gewalzt wird, und daß das teilweise Umlegen der Längsrippen dann in an sich bekannter Weise durch weiteres Walzen erfolgt, wobei gemäß der Erfindung 45 According to the present invention, racket plates for threshing machines with an undercut groove are to be completely rolled without it being necessary to subsequently cut the grooves into the metal. This is achieved by first rolling a plate with an open groove and lateral longitudinal ribs on one side and transverse racket ribs on the other side by means of a known rolling process, and then partially turning over the longitudinal ribs in a known manner Way is carried out by further rolling, according to the invention 45

die querliegenden Schlägerrippen in Quernuten einer entsprechenden Profilleiste eingesetzt und dann mit dieser Leiste, zusammen, wie bekannt, durch die Walzen geführt werden. Auf diese Weise ist es möglich, die Längsrippen ohne Beschädigung der Schlägerrippen umzulegen.and inserted the transverse racket ribs in transverse grooves of a corresponding profile strip then, together with this bar, as is known, are passed through the rollers. To this Way, it is possible to fold the longitudinal ribs without damaging the racket ribs.

Durch dieses Verfahren. können Schlägerplatten in einfacher und billiger Weise aus gewalztem Metall hergestellt werden, ohne daß irgendwelche Handarbeit erforderlich ist, nachdem das Walzen beendigt und die Platten zu den nötigen Längen zugeschnitten sind.Through this procedure. can racket plates can be produced in a simple and inexpensive manner from rolled metal without any manual labor is required after the rolling is finished and the panels are too are cut to the required lengths.

Auf den beiliegenden Zeichnungen zeigen Fig. i, 2 und 3 Walzen für die verschiedenen Arbeitsstufen des Verfahrens. Fig. 4 ist eine zu Fig. 3 gehörige Seitenansicht. Die Fig. 5, 6, 7 und 8 zeigen die Querschnittsform einer Schlägerplatte bei verschiedenen Stufen des Verfahrsen. Die Fig. 9 und 10 lassen im Querschnitt und im teilweisen Grundriß eine Schlägerplatte mit einem Befestigungsbolzen in seiner Lage erkennen. Die Fig. 11 und 12 stellen im Grundriß und im Querschnitt eine beim Walzen zur Anwendung kommende Profilleiste dar.In the accompanying drawings, Figs. 1, 2 and 3 show rollers for the various Working stages of the process. FIG. 4 is a side view associated with FIG. 3. Figures 5, 6, 7 8 and 8 show the cross-sectional shape of a club plate at different stages of FIG Traversing. 9 and 10 leave in cross section and in partial plan a racket plate with a fastening bolt in its Recognize the location. 11 and 12 represent in Floor plan and cross-section of a profile strip used for rolling.

Nach der dargestellten Ausführungsform ist die erste Reihe von Walzeh (Fig. 1) mit Nuten a versehen, um eine Stange b von rechtwinkligem oder ähnlichem Querschnitt zu erzeugen, wie in Fig. 5 gezeigt. Diese Stange wird darauf durch eine zweite Reihe von Nuten c, d geführt, welche vorteilhaft in demselben Walzenpaar wie die Nuten α eingeschnitten sind (Fig. 1). Die eine Walze trägt eine Nut c zur Bildung derAccording to the embodiment shown, the first row of rollers (FIG. 1) is provided with grooves a in order to produce a bar b of rectangular or similar cross-section, as shown in FIG. This rod is then passed through a second row of grooves c, d , which are advantageously cut into the same pair of rollers as the grooves α (FIG. 1). One roller carries a groove c to form the

outer surface of the club plate, while the other roller has grooves d which, as shown in Fig. 6, create on the lower surface of the plate grooves e, f, e and corresponding projections. According to the embodiment shown, the plate is then passed through two rollers (FIG. 2) which produce the racket ribs I on the outer surface, widen the grooves e, f, e and make the projections m sharper. To produce the ribs I on the outer surface of the racket rail, the rollers are provided with either right-handed or left-handed incisions h, h .

; After the cross-sectional shape shown in Fig. 7 has been produced, the racket plate is guided through further rollers (Fig. 3) which act on the lower surface provided with grooves e, f, e and fold the inner tongue strips m in such a way that the open channel f closes an undercut groove is formed, which can receive the heads of fastening screws r , as shown in FIGS. The height of the strips m is made so large that the upper edge of these strips comes to lie below the upper edge of the support surface q after folding, as shown in FIGS. In this last stage of the rolling process, a profile strip η is used (FIGS. 3, 4, 11 and 12) to guide the racket rail through the rollers while the ribs 111 are folded down. This is intended to avoid damage to the ribs I and to keep the rail in the correct position during this process.

The profile strip η itself is guided through the lower, i.e. the carrier roller, and its upper surface corresponds to the surface of the racket rail. The shape of the racket rail or plate is only changed by the upper roller by turning the ribs m .

The folding of the ribs is limited by an annular flange k on the upper roller.

For further guidance of the profile strip η with the racket plate or rail located therein in a known manner, a yoke plate 0 on a transverse rail or a frame p is used according to FIG. This plate is connected to a carrier rail p in such a position that the protruding tongue piece 0 enters the groove f of the rail to be rolled. A guide plate is arranged on the front side of the roller, while upper and lower support plates for the profile strip η are provided on the rear side of the rollers, but these are on. are not shown in the drawing.

The profile strip η is advantageously designed in the form of a long rail, as it corresponds to the length of the club plate to be rolled out. At the front end, the bar can be provided with a handle, as shown in FIGS. 4 and 11.

The drawn arrangement and design of the rollers for folding and partial Closing the grooves can be changed according to the shape of the club plate to be produced will. The shape of the undercut groove can of course also be different according to the shape of the screw heads be.
