Problems solved by technology

[0007] It is very common that the rivet nut deforms within the plastic material, causing material damage, such as the formation of cracks, necessitating the discarding of the part, thus losing time and significantly increasing costs
[0008] Also, with metal pins, the ends of the rivet nuts need to be coated with a corrosion resistant coating, which involves adding additional costs as mentioned above

Embodiment Construction

[0026] exist figure 1 As can be seen in , the traditional system of fastening rivet nuts 1 on synthetic plastic parts is achieved by means of conventional metal pins 3 which require corrosion protection at the ends of these pins 3 and which have Problems that may cause cracks in the plastic part 2.

[0027] Therefore, in order to avoid these problems and inconveniences, the system of the present invention preferably adopts such as figure 2 and 3 Riveting is performed ultrasonically as shown or by any other method as appropriate. For this purpose, the part of plastic material to which the rivet nut 1 is riveted has a plurality of protrusions 4 which are formed as part of the manufacturing process of the plastic part 2, preferably by injection moulding. These projections 4 pass through corresponding holes made for the rivet nut 1 . Riveting 3' is then performed by ultrasonic or other methods such as image 3 shown.

[0028] Such as Figure 4 and 5 As shown, the ultrason...

Abstract

A system for combining a riveting nut to a plastic material component fixes a metal riveting nut (1) on a plastic component (2), so as to connect the plastic component to other components; wherein the other components are metallic or nonmetallic. Preferably, the plastic component (2) manufactured by an injection mold comprises a plurality of noses (4) for riveting the riveting nut (1), and the noses (4) perforate the holes particularly arranged inside the riveting nut (1).

Description

technical field [0001] As the title of the description states, the invention relates to a system for incorporating rivet nuts into plastic components. The invention is based on riveting by means of ultrasound or any other mechanical method in order to avoid damage or cracks of the plastic part to which the rivet nut is bonded. This is used to combine with other components or to be fixed on other components by screws. [0002] The system is suitable for use in all types of industries that require or facilitate the joining of plastic parts to other parts, which may or may not be metal. In particular, one of the preferred applications may be in the field of aviation. Background technique [0003] It is increasingly common to use plastic materials to manufacture structures or structural components. They are widely used in the aerospace sector, where the combination of plastic materials and metal composites benefits their cost, their performance or the many possibilities offer...
