PAUL SCHRÖTER in NEUWIED. Vorrichtungen zur Herstellung von Wellblechen.PAUL SCHRÖTER in NEUWIED. Devices for the production of corrugated sheets.
Patentirt im Deutschen Reiche vom 16. Mai 1879 ab.Patented in the German Empire on May 16, 1879.
Die Vorrichtung, welche hier zur Herstellung von Wellblechen angewendet ist und welche durch nachfolgende Beschreibung und Zeichnung erläutert wird, ist in Verbindung mit einer Prefsvorrichtung irgend welcher Construction, jedoch mit veränderlichem Hub, ζ. Β. hydraulische Excenter-Schrauben- oder Keilpresse zu denken. Sie unterscheidet sich dadurch wesentlich von den bisher bekannten älteren Vorrichtungen, sowie von der Maschine, Patent No. 2469 und 2490, dafs sie, um die Sprödigkeit des Materials zu überwinden und durch einen Druck eine ganze Welle in beliebiger Tiefe herstellen zu können, die grofse, beim Herüberziehen des Bleches über die Wulsten entstehende gleitende Reibung, welche das Material bis zum Zerreifsen beansprucht, in rollende bezw. Zapfenreibung verwandelt, indem die drückenden Wulste aus Stahlwalzen α bestehen, welche in geeigneter Weise in Bronzeschalen gelagert sind. The device, which is used here for the production of corrugated metal sheets and which is explained by the following description and drawing, is in connection with a pressing device of any construction, but with a variable stroke, ζ. Β. think hydraulic eccentric screw or wedge press. It differs significantly from the previously known older devices, as well as from the machine, patent no. 2469 and 2490, that in order to overcome the brittleness of the material and to be able to produce a whole corrugation at any depth by means of a pressure, the great sliding friction which occurs when the sheet is pulled over the beads, which stresses the material until it tears, in rolling respectively. Converted journal friction by the pressing beads consist of steel rollers α , which are stored in a suitable manner in bronze shells.
Die Wulste, über welchen die vorher geprefste Welle liegt, sind fest und ist in ihnen das Blech durch eine Leiste c gehalten, die mittelst starker Federn d angedrückt und vom oberen Stempel S nach Vollendung der Operation herausgehoben wird, so dafs das Blech ebenfalls herausgehoben und weitergelegt werden kann. Der Hub des Prefsstempels ist somit der dreifache der Wellentiefe bezw. ein wenig mehr.The bulges, over which the previously pressed shaft lies, are fixed and the sheet metal is held in them by a bar c , which is pressed on by means of strong springs d and lifted out by the upper punch S after the operation has been completed, so that the sheet metal is also lifted out and can be passed on. The stroke of the press ram is thus three times the shaft depth respectively. a little more.
Dieser Hub wird veränderlich eingerichtet, um nicht unnöthig hoch zu heben und um beliebig tief zu drücken.This hub is set up variably so as not to lift unnecessarily and at any time to press deep.
Die Matrize der Prefsvorrichtung besteht aus drei Theilen M^ ΛΡ M3, welche gegeneinander verstellbar sind und zwar zu dem Zwecke, um nach geprefster ganzer Welle, während der Stempel wieder um '/3 gehoben und im Begriff ist, die übrigen 2/3 seines Hubes zurückzulegen mittelst der Schraube H oder durch Hebel oder Keilvorrichtung etc. die Matrize M' gegen M2 vorzvtschieben, so dafs die geprefste Welle noch in horizontaler Richtung zusammengedrückt wird; man erzielt dadurch, dafs bei verticalen, Fig. 3, oder S-förmig übergebogenen, Fig. 4, Stegen die Form eine genauere wird.The die of Prefsvorrichtung consists of three parts M ^ ΛΡ M 3, which are mutually adjustable and namely for the purpose, in order to geprefster entire shaft, while the punch again by '/ High 3 and is about the remaining 2/3 of its To cover the stroke by means of the screw H or by means of a lever or wedge device, etc., push the die M ' forward against M 2 so that the pressed shaft is still compressed in the horizontal direction; it is thereby achieved that with vertical, Fig. 3, or S-shaped overbending, Fig. 4, the shape becomes more precise.
Um letztere Form, Fig. 4, herzustellen, wird die Matrize M' auch so construirt, dafs sie hinten gehoben, also um den Punkt/ gedreht werden kann, so dafs der obere Theil mit der Stahlrolle mehr drückt, als der untere. Nach erfolgter genügender Pressung kehrt M1 wieder in seine Stellung zurück. Bei flachen Wellblechen ist diese Operation nicht nöthig.In order to produce the latter shape, Fig. 4, the die M 'is also constructed in such a way that it can be raised at the rear, i.e. rotated about the point /, so that the upper part with the steel roller presses more than the lower part. After sufficient compression, M 1 returns to its position. This operation is not necessary with flat corrugated iron.
Die Verschiebung von M' und ebenfalls von M3 hat aber auch den Zweck, überhaupt vor Beginn der Operation die Stellung der Matrizentheile zu reguliren, so dafs Wellen verschiedener Blechstärke, verschiedener Form und Länge in derselben Vorrichtung hergestellt werden können und derselben daher den Charakter der universalen geben.The displacement of M ' and also of M 3 , however, also has the purpose of regulating the position of the die parts before the operation begins, so that corrugations of different sheet thicknesses, different shapes and lengths can be produced in the same device and therefore have the character of universal give.
Beispielsweise sind hiermit Wellen flacher Form, Fig. 5, ferner Wellen ähnlich der Form wie in Fig. 8 und 9 herstellbar.For example, waves of a flat shape, FIG. 5, are also waves similar to the shape as in FIGS. 8 and 9 can be produced.
