Abstract

Ein Pressenkopf (1) für das Verbinden von Rohrleitungen besitzt zwei doppelarmige Zangenhebel (2, 3), die um erste fest beabstandete Gelenkachsen (4, 5) schwenkbar in einer Haltevorrichtung (6) gelagert und durch Spreizrollen (7, 8) antreibbar sind. Dabei sind die einen Enden (2a, 3a) der Zangenhebel (2, 3) mit Steuerflächen (2b, 3b) zum Abrollen der Spreizrollen (7, 8) und zum Zusammenführen der anderen Enden (2c, 3c) der Zangenhebel (2, 3) zusammen mit dort gelagerten Druckstücken (17, 18) versehen. Die Anordnung ist spiegelsymmetrisch zu einer Mittenebene (E) des Pressenkopfes (1) ausgebildet. Um dabei mit einfachen und zuverlässigen Mitteln exakte und praktisch reibungsfreie Parallelbewegungen von nur zwei antiparallel beweglichen Arbeitsflächen an den Druckstücken (17, 18) zu erzeugen, sind die Druckstücke (17, 18) durch zwei gegeneinander wirkende Parallelogrammlenker-Anordnungen (P1, P2) an der Haltevorrichtung (6) und an den Zangenhebeln (2, 3) gelagert. Der Pressenkopf kann dabei Preßstücke (25, 26) mit Arbeitsflächen (21, 22) für das axiale oder für das radiale Verpressen von Rohrkupplungen tragen, und er kann entweder fest oder auswechselbar mit einer Antriebsmaschine verbunden sein.

Figure 00000001
A press head (1) for connecting pipes has two double-arm caliper levers (2, 3) which are pivotally mounted about first fixedly spaced hinge axes (4, 5) in a holding device (6) and driven by spreading rollers (7, 8). In this case, the one ends (2a, 3a) of the caliper levers (2, 3) with control surfaces (2b, 3b) for unrolling the spreader rollers (7, 8) and for merging the other ends (2c, 3c) of the caliper levers (2, 3 ) together with pressure elements (17, 18) mounted there. The arrangement is mirror-symmetrical to a center plane (E) of the press head (1). In order to produce with simple and reliable means exact and virtually frictionless parallel movements of only two antiparallel movable work surfaces on the pressure pieces (17, 18), the pressure pieces (17, 18) by two counteracting parallelogram linkages arrangements (P1, P2) the holding device (6) and on the forceps levers (2, 3) stored. The press head can while pressing pieces (25, 26) with work surfaces (21, 22) for the axial or for the radial compression of pipe couplings wear, and it can be connected either fixed or interchangeable with a prime mover.
