ABSTRACT:
In the case of certain series-produced finished parts, such as switch cross ties, the precision of the assembly of components is of decisive importance. The components should neither be damaged nor should their position be changed during assembly. During the assembly process, they have to be nonslidably fastened in the casing, at the same time the fastening should not damage the finished part or the component during the movements occurring in the hardening process or during the removal of the casing from the finished part. The temporary connection uses a blind rivet which can be introduced and driven in from above with its stem through the bore of the bottom plate carrying the component, as well as through the bore determining the position of the component in the casing plate, and is solidly anchored on the outside of the casing plate by rivet-head-like enlargement.
