PCT No. PCT/EP89/00622 Sec. 371 Date Aug. 14, 1989 Sec. 102(e) Date Aug. 14, 1989 PCT Filed Jun. 2, 1989 PCT Pub. No. WO90/15191 PCT Pub. Date Dec. 13, 1990.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 non-slidably fastened in the casing, at the same time the fastening is not allowed to damage finished part, respectively the component, neither during the movements occuring in the hardening process, nor during the removal of the casing from the finished part, i.e. a fastening device has also to be easily detachable. The invention proposes as a temporary connection means the use of a blind rivet (7), which can be introduced and hammered in from above and pushed in from above with its stem (8) through the bore (20) of the bottom plate (19) carrying the component (18), as well as through the bore (20) determining the position of the component (18) in the casing plate (1), and is solidly anchored on the outside of the casing plate (1) by a rivet-head-like enlargement (9). |
