Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die nachstehend beschriebene Maschine dient dazu, Formstücke und Halbbögen aller Arten auf hohen Druck hydraulisch sicher und schnell zu prüfen.The machine described below is used to cut shaped pieces and half-arcs of all kinds to check hydraulically safely and quickly for high pressure.

Die in Fig. 1 bis 5 dargestellte Maschine, die zur Prüfung von Halbbögen auch die Grundform eines Halbkreises erhalten kann, wird durch eine durchbrochene Platte A gebildet, welche von einer in einem Zapfen auslaufenden Säule C und Füfsen B getragen wird. Auf einer aiii Rande der Platte A befindlichen Prismenführung α gleiten zwei Arme D, die bei b durch ein Scharnier mit einander verbunden sind und je einen supportartigen, um seine senkrechte Achse drehbaren Bock c oder h tragen. In einem Schlitz der Mittelrippe e gleitet die durch eine Schraubenspindel f bewegliche Aufspannvorrichtung E zur Aufnahme des zu prüfenden Formstückes.The machine shown in FIGS. 1 to 5, which can also have the basic shape of a semicircle for testing semi-arcs, is formed by a perforated plate A which is supported by a column C and feet B ending in a pin. Two arms D slide on a prism guide α located aiii edge of plate A , which are connected to one another by a hinge at b and each carry a support-like bracket c or h rotatable about its vertical axis. The clamping device E , which is movable by a screw spindle f, slides in a slot in the central rib e for receiving the molded piece to be tested.

Diese Vorrichtung besteht aus einer horizontalen Platte mit rechtwinklig darauf befindlicher schwalbenschwanzartiger Prismenführung. In letzterer werden vermittelst einer Schraubenspindel mit Rechts- und Linksgewinde zwei in einander schiebbare Backen bewegt, welche das zu probirende Rohrstück stets an vier Punkten des Umfanges festhalten.This device consists of a horizontal plate with a right angle on it dovetail-like prismatic guide. In the latter, a screw spindle with right-hand and left-hand threads is used two jaws which can be pushed into each other and which always touch the piece of pipe to be tried record four points of the circumference.

Die Wangen D können von Hand oder vermittelst des Getriebes F am Umfange der Platte A eingestellt und durch Bolzen g in ihrer Lage festgehalten werden.The cheeks D can be adjusted by hand or by means of the gear F on the circumference of the plate A and held in their position by bolts g.

Ist nun das zu prüfende Rohrstück in der Aufspannvorrichtung E festgeklemmt und diese durch Schrauben m am Gestell festgezogen, so werden die beiden Wangen D gegen die Rohrenden geschoben, festgestellt und die Deckel i und k, welche die erforderlichen Wasserzuführungs- und Luftentleerungsvorrichtungen enthalten, mittelst Schraube und Handrades oder vermittelst eines hydraulischen Prefskolbens und Cylinders (Fig. 5) angeprefst.If the pipe section to be tested is now clamped in the clamping device E and this is tightened on the frame with screws m , the two cheeks D are pushed against the pipe ends and fixed and the covers i and k, which contain the necessary water supply and air evacuation devices, are screwed and handwheel or by means of a hydraulic piston and cylinder (Fig. 5).

Claims (1)

Patent-Anspruch:Patent claim: Maschine zur Prüfung von Knierohren durch inneren Wasserdruck, bei welcher, um die Anpassung an Knierohre von verschiedener Stärke, Länge und Gestalt zu ermöglichen, die nöthigen zwei Verschlufsdeckel i und k je mit einem um seine senkrechte Achse drehbaren supportartigen Bock c stellbar verbunden sind, der auf einer Wange D gleitet, deren Winkelstellung zur anderen Wange durch Drehung um einen den beiden Wangen gemeinschaftlichen Zapfen verändert werden kann.Machine for testing knee tubes by internal water pressure, in which, in order to allow adaptation to knee tubes of different thickness, length and shape, the necessary two closure lids i and k are each adjustably connected to a support-like bracket c rotatable about its vertical axis, which slides on a cheek D , the angular position of which can be changed to the other cheek by rotating around a pin common to the two cheeks.
