KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Vorliegende Erfindung betrifft eine Maschine zum Prüfen von Rohren beliebiger Längen und Formen. Außerdem hat diese Maschine den großen Vorteil, daß die zu prüfenden Rohre beim Abpressen auch auf Zug, genau so, wie es im Betriebe tatsächlich der Fall ist, beansprucht werden. Die Einrichtung derselben ist folgendermaßen:The present invention relates to a machine for testing pipes of any length and shapes. In addition, this machine has the great advantage that the Pipes when pressed, even when pulled, exactly as it is actually the case in the company is to be claimed. The establishment of the same is as follows:
Die Maschine besteht der Hauptsache nachThe main thing is that the machine persists
ίο aus einem stationären und einem nach allen Richtungen hin verfahrbaren Einspannkopf unter Weglassung der bis jetzt immer gebräuchlichen. Verbindungsstangen der beiden Köpfe. Die eigentliche Einspannung geschieht hydraulisch, wie nachstehend beschrieben.ίο from a stationary and one after all Directions movable clamping head omitting the one that has always been used up to now. Connecting rods of the two heads. The actual clamping is done hydraulically, as described below.
Man setzt das zu prüfende Rohr α gegen den Kopf b, welcher am Umfange drei oder mehrere, in den Schlitten c sich führende und mittels der Spindeln d und Muttern e, für größere und kleinere Rohre, einstellbare Hebel oder Klauen f besitzt, und läßt Druckwasser von A aus in den Zylinder eintreten, so wird der Differentialkolben g nach rechts gedrückt und das Rohr α durch die Klauen f vermittels der Stangen h und den mit dem Kolben g· in Verbindung stehenden Hebel i gegen den Kopf b gedrückt. An dem verfahrbaren Kopf k ist die erste Einspannung des Rohres a, welche durch das Handrad I, Spindel m, Hebel 0, Laschen η und Hebel i geschieht, aus dem Grunde von Hand aus angeordnet, weil eine Zuführung des Druckwassers zu umständlich wäre, da der Kopf einmal hier, ein andermal dort zu stehen kommt. Ist das Rohr α nun provisorisch rechts und links eingespannt, so läßt man das Wasser durch das Ventil f am festen Einspannkopf eintreten, wodurch das Prüfrohr α mit Wasser gefüllt wird. Hat sich das Rohr ganz gefüllt und tritt durch ein weiteres, gewaltsames Zuführen des Wassers eine höhere Spannung in dem Rohr α auf, so überträgt sich der Druck einerseits auf den Differentialkolben g·, andererseits durch das Entlüftungsrohr u auf den Kolben r des verschiebbaren Einspannkopfes. Der Kolben r wird nach links gedrückt, wodurch das Rohr a mittels der Klauen f immer fester gegen die Köpfe angepreßt wird, infolge wovon das Druckwasser an den Stirnenden nicht austreten kann. Zum Zurückschieben der KoI-ben r und g dienen die Gewichte s.It sets the test tube α b to the head, which at the circumference, three or more, c in the carriage itself leading and by means of the spindles d and nuts e, for larger and smaller pipes, adjustable lever or claw f has, and can be pressurized water enter the cylinder from A , the differential piston g is pressed to the right and the tube α is pressed against the head b by the claws f by means of the rods h and the lever i connected to the piston g. On the movable head k , the first clamping of the pipe a, which is done by the handwheel I, spindle m, lever 0, tabs η and lever i, is arranged by hand because supplying the pressurized water would be too cumbersome there the head comes to stand one time here, another time there. If the pipe α is now temporarily clamped on the right and left, the water is allowed to enter through the valve f on the fixed clamping head, whereby the test pipe α is filled with water. If the pipe is completely full and a further, forcible supply of water causes a higher tension in the pipe α , the pressure is transferred on the one hand to the differential piston g and on the other hand through the vent pipe u to the piston r of the movable clamping head. The piston r is pressed to the left, whereby the pipe a is pressed more and more tightly against the heads by means of the claws f , as a result of which the pressurized water cannot escape at the front ends. The weights s are used to push back the buckets r and g.
