Bulk forming technology of connecting pin
Koukal, Vojtěch ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The project of master’s thesis elaborated within engineering studies of engineering technology deals with concept of manufacturing procedure of connecting pin made of steel 11 320 5R with cold forming. Two variants of production technique were projected based on the literature study of the cold heading and cold extrusion. Selected variant, for which the technological calculation was accomplished, consists of five forming operations. Manufacture was projected for multistage automatic forming machine TPM 8-A made by manufacturer Šmeral Brno with nominal forming force 1000 kN. Tool steel 19 436 was chosen as a material of extrusion and heading tools.

Bulk forming technology of cover nut
Dušek, Otakar ; Dohnal, Ivo (referee) ; Forejt, Milan (advisor)
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.
