摘要:
The invention relates to a method for producing a component join, comprising the following steps: providing a first component (1) that is made of a thermoplastic plastic material at least in the region of a portion of the surface thereof; providing a ball (3) that is made of a thermoplastic plastic material in at least one region of the surface thereof; pressing the ball (3) on the first component (1) in such a way that the thermoplastic plastic material of the ball (3) comes into contact with the thermoplastic plastic material of the first component (1); vibrating the ball (3) using an ultrasonic sonotrode (4) and welding the ball (3) with the first component (1); providing a second component having a through hole; bringing the second component (6) to the first component in such a way that the ball (3) projects at least into the through hole (6a) of the second component (6) or a piece projects a long way through the through hole (6a); clipping a clip element (7) to the ball (3), wherein the clip element (7) projects beyond the through hole (6a) and joins both components (1, 6) to one another in an interlocking and/or force-locked manner.

The invention relates to a connecting device, comprising a clip element, which has a section that is elastic in a radial direction and that can be clipped onto a male fastening element while being elastically expanded in the process, and a securing element, which can be slid onto the clip element in a sliding direction, in particular when the clip element is clipped onto a male fastening element, wherein the securing element has a sleeve-like section, which is in contact with the elastic section of the clip element from the outside when the securing element is slid onto the clip element. The clip element and the securing element are injection-molded from the same plastic material or from different plastic materials.

The invention relates to a component connection comprising - a first component (1) which has a through-hole (2); - a clip element (3) which has a shaft-like portion (3a) that has a first end (3b) and a second end (3c) facing away from the first end, wherein - at least one flexurally elastic first formfitting element (3b') protrudes laterally from the first end, said first formfitting element covering the through-hole on a first face of a wall of the first component and - a second formfitting element (3') protrudes laterally from the second end, said second formfitting element covering the through-hole on a second wall face opposite the first face; and - a connection or securing element (4) which is inserted into a central hole (3d) of the clip element and which has at least one ball (4a-4d). The diameter of the at least one ball corresponds at least to the width of the central hole such that the shaft-like portion is radially expanded to at least such a width that a press fit is produced between the shaft-like portion and the through-hole.

The invention relates to a plastic component (10) comprising a connecting element (20) that includes an attachment portion (21) protruding at least in part from the plastic component (10) as well as an anchoring portion (23), by means of which the connecting element (20) is releasably connected to the plastic component and which has a smaller cross-sectional diameter than the attachment portion (21).
摘要:
Disclosed is a method for producing vehicle parts, particularly shell parts for vehicles, according to which a three-dimensionally preformed semi-finished or finished standard part, especially a standard shell part, is produced for a serially manufactured vehicle type. An individualized part is then produced from the preformed standard part (1) by subsequently embossing a three-dimensional contour (2) into the standard part by means of a spike-type reshaping tool (14) which is pressed against the standard part from one side while being displaced relative to said standard part.
