Popis:	The diploma thesis suggests a producing plan of the cover nut using cold forming technology. The component will be made of the structural steel 11 320 5R. Size of its assumed annual production is 800 000 pieces. The best option was chosen from four suggested production versions. A wire with a diameter of 13.2 mm was designed as a semi-product. The component will be made in four forming operations. Roll forming machine TPM 8 (produced by Šmeral Brno) with a nominal force of 1000 kN was elected for the proposed manufacturing technology. Drawing documentation was elaborated, which includes drawing of the rolling tool assembly and drawing of tools for 3rd operation (backward extrusion). The results of the economic evaluation shows that the production cost of one nut is 1 CZK.
