A process and a device produces an assembly linkage on a hollow profile which is shaped for the installation of the assembly part by internal high-pressure remodeling. In order to achieve the shaping of an assembly linkage in a component space-saving, for a subsequent assembly correctly positioned, and with regard to its contour exactly fitted to the assembly part, in simple manner and even with high degrees of remodeling in a secure process, the hollow profile, under internal pressure, which is smaller than the remodeling pressure, is indented at the place of the to-be-produced assembly linkage by a die and by forming a rough contour. Afterward, while the die remains in this indenting position, a fluid high pressure is created in the hollow profile. Thereby, the hollow profile sides surrounding the die are molded to the external contour of the die, and that after releasing the fluid high pressure and the subsequent removal of the die, the finished trough-shaped assembly linkage is released.
Process for manufacturing a trough-shaped assembly connection from a hollow profile which is shaped for the attachment of an assembly part by internal high-pressure remodeling, comprising the step of indenting the hollow profile at an internal pressure which is lower than a remodeling pressure, by a die at a point of the to-be-manufactured assembly connection;
Apparatus for manufacturing an assembly connection from a hollow profile with an internal high-pressure tool into an engraving face thereof the hollow profile is insertable, comprising a bore in the face into which a die is guided, the die being controllably arranged such that, with the hollow profile inserted in the apparatus, the die is drivable into the engraving face for indenting the hollow profile at pressure conditions below the remodeling pressure and prior to internal high-pressure pressure and thereafter being retractable from the engraving face, and during the remodeling process of the hollow profile, against the remodeling pressure, remaining backstopped in an indenting position.
