AI Technical Summary

Technical Problem

Conventional cladding elements require additional reinforcing elements like hat profiles or U- or L-profiles, which are welded onto sheet metal panels, leading to heat-induced distortion, surface contaminants, and additional manufacturing steps to achieve structural strength and aesthetic quality.

Method used

A cladding element made of a metal sheet with perforated bending edges and corner cutouts, forming a hollow frame, secured by rivet nuts, which provides rigidity without welding, allowing for cost-effective and visually appealing assembly.

Benefits of technology

The solution enhances mechanical stability and reduces manufacturing complexity by eliminating welding, minimizing distortion and surface contaminants, while enabling efficient assembly of large cladding elements into complex components.

Abstract

A cladding element (10), in particular for a machine cladding or a cabin, and a method for its manufacture are described, which is made from a metal sheet (12) with a rectangular basic shape, which comprises several adjacent and at least partially perforated bending edges (14,...,20) on each of its side edges and which has a cutout in each corner region, which is shaped such that by bending the metal sheet (12) along the bending edges (14,...,20) a frame (22) running along the outer circumference in the form of a hollow body formed at least in sections is created and that in the corner areas two sheet metal sections overlap, each of which is connected to the other by a rivet nut (38) having an internal thread (48), which gives the cladding element (10) the necessary stiffness, wherein one or more further rivet nuts (40) are formed on the frame (22) with respect to their internal threads in the same orientation to the rivet nuts (38) at the corner areas.
