Description
Gegenstand der Erfindung isst eine liegende Metallrohrpresse mit nach hinten durch den: Zylinderboden gezogenem Preßplunger und durch den hohlen, Preßplunbger laufender Dornstange. Bei den. bisher bekanntgewordenen, Bauarten dieser Maschine wurde die Dornstange inm Preßpluniger geführt, so, daß also die Werkzeuge jede Bewegung,des Plungers in, radialer Richtung mitmachten. Bekanntlich verschleißen .die Stopfbüchsführungen und Führungen des Plungers infolge des Eigengewichtes und einseitigen Auftreffens der in den Zylinder einströmenden Wassermassen auf den Plunger einseitig.The subject of the invention is followed by a horizontal metal pipe press at the back through the plunger pulled from the cylinder base and through the hollow plunger running mandrel bar. Both. previously known, types of this machine the mandrel bar was guided in the Preßpluniger, so that the tools every movement, des Take part in the plungers in the radial direction. As is well known, the gland guides wear out and guides the plunger due to its own weight and one-sided impact of the water masses flowing into the cylinder on the plunger on one side.
Die Folge hiervon, war, daß die Führungen der Werkzeuge, bestehend-aus Preßstempel und Lochdorn mit Lochdornstange, erhöhtem Verschleiß unterworfen waren, so daß nach kurzer Betriebszeit sich die vorgenannten Werkzeuge einseitig zur Rezipientenbohrung stellten.The consequence of this was that the guides of the tools consisted of Press ram and piercer with piercer rod were subject to increased wear, so that after a short period of operation the aforementioned tools are on one side to the recipient bore posed.
Die Erfindung schlägt nun. vor, den Preßplunger an beiden Enden durch Gleitstücke und unabhängig hiervon die Werkzeuge, bestehend aus Preß,stempel und Lochdorn mit Dornstange, ebenfalls durch besondere Gleitstücke zu führen. Es werden also die Werkzeuge mit ihrer Führung nicht unnötigerweise durch den Preßplunger belastet, so daß die eigentlichen Werkzeugführungen, geringfügigem Verschleiß -unterworfen wenden. Um die Genauigkeit der Arbeitsweise der Presse zu -steigern, sind die Gleitbahnen für die Plungerführungen und für die Werkzeugführungen voneinander zu trennen: und jede für sich nachstel.lbar ausgeführt, wobei die Nachstellung entweder durch Nachstellung der Gleitstücke selbst oder aber durch Nachstellen der Gleitbahnen erreicht wenden kann.The invention now suggests. before pushing the plunger through at both ends Sliders and independently of this the tools, consisting of press, stamp and Perforating mandrel with mandrel rod, also to be guided through special sliding pieces. It will so the tools with their guidance not unnecessarily through the plunger loaded, so that the actual tool guides, subject to slight wear turn around. In order to increase the accuracy of the operation of the press, the slideways are for the plunger guides and for the tool guides to separate from each other: and each carried out for itself nachstel.lbar, with the adjustment either by adjustment the sliders themselves or by adjusting the slideways can.
Die Erfindung ist in den. Abb. I bis III dargestellt; im einzelnen zeigt Abb. I einen Längsschnitt durch die Maschine, Abb.. II einen Querschnitt nach Linie A-B und. Abb, III einen Querschnitt nach der Linie C-D. Es bezeichnen i den Preßzylinder, 2 die PreSSensäuJen, 3 das Rezip.ientenquerhaupt, 4 den Rezipienten, 5 die Matrize und 6 den Preßplunger, der von den. Gleitstücken 7 und 8 getragen wird. Das Gleitstück 7 läuft auf der Bahn: g, das Gleitstück 8 auf der Bahn, yo. In .dem hohlgebohrten Plunger 6 läuft die Dornstange i i, die sich hinten auf dem Gleitstück 12 abstützt und vorn auf dem Werkzeugträger 13 vermittels des kugelbeweglichen. Lagers 1g. Am vorderen Ende trägt .die Dornstange i i den Dorn 15, während an dem Werkzeugträger 13 der Preßstempel i6.befestigt ist. Das Gleitstück 12 läuft auf der Bahn 17 und der Werkzeugträger 13 auf der Bahn: i8. In dem Zylinder i9 bewegt sich der Lochplunger 2o, der an .der Dornstange i i angreift. Die Rrückzwgzylinder und -plunger sind nicht dargestellt. Die Verbindung zwischen dem Plunger 6 und dem Werkzeugträger 13 ist lose gehalten, und es ist, um Kantenpressungen zu vermeiden, an der Verbindungsstelle beider Teile eine Kugelscheibe 21 eingeschaltet, so daß am Plunger durch einseitige Wassereinführung auftretende einseitige Kräfte sich auf die Werkzeugführung nicht auswirken können.The invention is in the. Fig. I to III shown; in detail Fig. I shows a longitudinal section through the machine, Fig. II shows a cross section Line A-B and. Fig, III a cross-section along the line C-D. I denote the Press cylinders, 2 the press columns, 3 the recipient crosshead, 4 the recipient, 5 the die and 6 the plunger, which is used by the. Sliders 7 and 8 carried will. The slide 7 runs on the track: g, the slide 8 on the track, yo. In .dem the hollow bored plunger 6, the mandrel rod i i runs, which is located on the back of the Slider 12 is supported and at the front on the tool carrier 13 by means of the spherically movable. Bearing 1g. At the front end carries .die mandrel rod i i the mandrel 15, while on the Tool carrier 13 of the ram i6. Is attached. The slider 12 runs up the track 17 and the tool carrier 13 on the track: i8. Moved in the cylinder i9 the hole plunger 2o, which attacks the mandrel bar i i. The return cylinder and plungers are not shown. The connection between the plunger 6 and the Tool carrier 13 is held loosely, and it is, in order to avoid edge pressure, turned on at the junction of the two parts a spherical disk 21, so that unilateral forces occurring at the plunger due to unilateral water introduction cannot affect the tool guidance.
