JOINING METHOD, AND DEVICE FOR SUCH

Abstract: a method and a device for obtaining a joint between two surfaces of two parts that have a simple curvature are proposed in which a mandrel is placed below the first surface, which contains a moving stamp in its interior. a template is placed above the second surface, which has a deep drawing opening. the stamp is moved along the surface normals of the two surfaces, such that material forming the two surfaces is forced into the deep drawing opening, wherein the deep drawn and compressed portion of the first surface engages behind the remaining part of the second surface to obtain a form-fit connection between the two surfaces. the stamp blocks a channel inside the mandrel until pressure from a medium therein causes the stamp to move.
