The invention relates to a pressing tool (2) for the permanent connection of workpieces (14, 16, 18, 30, 34) having two pivot elements (4), each of them having a pressing jaw (10), and having at least one rotational axis (6) on which the pivot elements are hinged, wherein the inner contours of the opposing pressing jaws (10) form a receiving area (12). The present invention is based on the technical problem of providing an alternative pressing tool (2) with which a permanent connection can be produced between workpieces (14, 16, 18, 30, 34) by axial pressing-together. The technical problem is solved in that the inner contours have at least one slide face (2) which is inclined relative to the receiving area axis (20). A pressing tool (2) can thus be provided which, starting from a radially inward movement, performs a pressing-together in the axial direction, nonetheless requires little installation space, and offers weight advantages due to a smaller axial extension, for example. Furthermore, the invention relates to an attachment for a pressing tool (2) and a method for the permanent connection of workpieces using a pressing tool.
L'invention concerne un outil de compression (2) pour l'assemblage permanent de pièces (14, 16, 18, 30, 34), avec deux éléments pivotants (4) présentant chacun une mâchoire de pressage (10), et avec au moins un axe de rotation (6) sur lequel sont articulés les éléments pivotants (4), sachant que les contours intérieurs des mâchoires de pressage en vis-à-vis (10) forment une zone réceptrice (12). L'invention vise à indiquer une variante d'outil de compression (2) qui permette de réaliser un assemblage permanent entre des pièces (14, 16, 18, 30, 34) par compression axiale. A cet effet, selon l'invention, les contours intérieurs présentent au moins une surface de glissement (22) inclinée vers l'axe (20) de la zone réceptrice (20). On peut ainsi fournir un outil de compression (2) qui, en partant d'un mouvement radialement vers l'intérieur, accomplit une compression en direction axiale, tout en nécessitant un faible espace de montage et en apportant des avantages de poids, par exemple par une étendue axiale réduite. L'invention concerne en outre un embout pour un outil de compression (2), et un procédé d'assemblage permanent de pièces en utilisant un outil de compression.
