Benefits of technology

The invention provides a method, a joining element, and a device for fast and easy production of strong junctions between plate-shaped components, particularly those made of thermoplastic plastic materials. The method involves incorporating a bore into the first component, welding the supporting plate to the first component, and joining the first and second components by incorporating a joining means into the second component. The weld joint between the first and second components has high mechanical load capacity, is resistant to delaminations and corrosion processes, and the joining element becomes an integral part of the first component. The device for realizing the junction is simple and easy to use, and can be used to produce strong junctions between plate-shaped components.

Problems solved by technology

Joining plate-shaped components, which only have low material thickness with respect to superficial extent, to other components or components also realized in plate-shape proves to be costly, because on many occasions, due to the low material thickness, joining screws, rivets, or the like, cannot be inserted directly into the components.
Due to a plurality of steps, the above mentioned methods or joining means require relatively intensive installation work.
Furthermore, in particular in components with fiber reinforced plastic materials, there is the risk of delaminations in the region of the junctions.
Both the rivets for fastening the plate nut and the expansible sleeve for central fastening of the plate nut moreover imply the risk of corrosion processes because components made of different materials are adjacent.

Embodiment Construction

[0029]FIG. 1 shows a top view of the inventive joining element.

[0030]The joining element 1 comprises among other things a supporting plate 2, preferably realized to be circular, into which a supporting plate bore 3 is incorporated approximately in the middle. The supporting plate 2 can also have a geometric shape which differs from the circular shape. The supporting plate 2 is joined to the first component 4 by a weld joint.

[0031]In order to enable a weld joint between the first component 4 and the supporting plate 2 of the joining element 1, the supporting plate 2 is formed according to the invention of a thermoplastic plastic material, which additionally can have fiber reinforcement. The supporting plate 2 can e.g. be formed of a plastic material, such as polyetheretherketone (PEEK), polyetherimide (PEI), or the like.

[0032]Alternatively, it is also possible to form the supporting plate 2 of a thermosetting material, wherein a bottom side of the supporting plate 2, which cannot be ...

Abstract

This invention firstly relates to a method for joining a first component made of a plastic material, in particular a thermoplastic and / or thermosetting plastic material, to a second component by applying a joining element on the first component, wherein the joining element has a supporting plate formed of a thermoplastic and / or thermosetting plastic material and comprising a connecting means and a supporting plate bore. The method comprising the steps of incorporating a bore into the first component; welding the supporting plate to the first component; and joining the first component and the second component by incorporating a joining means arranged on the second component into the connecting means. Due to welding of the supporting plate to the first component, a rivet joint, otherwise generally required for joining the supporting plate to the first component, can be omitted, whereby the production of a junction by means of the inventive joining means is considerably simplified. Moreover, weakening of the first component as well as formation of corrosion processes due to different materials used for riveting being adjacent can be avoided. In addition, the invention relates to a joining element for creating a junction in accordance with the method. Furthermore, the invention relates to a device, in particular for performing the method.
