Production of short shaft by extrusion
Hondl, Jiří ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
HONDL Jiří: Production of short shaft by extrusion. The project prepared as part of the Master-degree studies in the Engineering technology concerns the technology design for manufacturing a short shaft by extrusion. On the basis of the study cold forming methods and problems and following technical calculations was designed a four steps process of forming. Semifinished product has a cylinder shape with a diameter of 18mm and a length of 51,2mm. The production is designed for automatic multistage press TPZK 25 with nominal pressing force of 5 000kN from Czech producer and supplier of machinery Šmeral Brno company. Tools are made of tool steel, extrusion punch and extrusion die is designed of 19 830.4 steel, and extrusion die´s band is designed of 19 733.4 steel. Tools are designed to be improved by hardening and drawing.

Forming technology production of ending of brake hose
Obůrka, Miloš ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The purpose of the diploma thesis elaborated during studies of Engineering technology is to project the technological process for production of brake hose end made of 12010.3 steel by cold forming. Based on the study of the cold forming problems and following technical calculations of the production process was designed a 3 steps process of forming. As a semiproduct was chosen wire stub with a diameter of 11.2 mm and a length of 27mm. The production is designed for automatic multistage press TPZK 25 from local manufacturers Šmeral Brno, a.s.

Production of components "control element" extrusion
Stříbrný, Jan ; Forejt, Milan (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated in frame of engineering studies branch Engineering technology submitted technology design of manufacturing a control element by extrusion – part of aluminium alloy EN AW 6082. On the base of literature study of the cold forming problems and calculations was designed procedure on one operation. Semi-finished product was chosen cut block rods with a diameter of 43.5 mm and length of 17,4 mm. The production is designed for toggle stamping press LLR 400 (producer Šmeral Brno a.s.) with a nominal force 4000 kN. Extrusion punch and extrusion die are made of steel alloy 19 830.4 heat-worked according to drawing documentation.

Metal forming production of bush by cold extrusion.
Šimeček, Tomáš ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
ŠIMEČEK Tomáš: Metal forming production of bush by cold extrusion. The project elaborated in frame of bachelor study degree brings a proposal of step by step metal forming production of bush by cold extrusion. Workpiece is made of normalized circle-shaped bar using 12 050 steel. The step by step production is based on literary pursuit of volumetric forming and calculation and is designed into five steps containing cutting, pressing and extrusion. These operations will be done on multistage pressing automatic machine TPZK 25 manufactured by ŠMERAL Brno, plc. with nominal pressing force of 5MN. Semi-finished product is placed into tooling´s workspace with manipulator. Final part extraction is solved with ejector integrated in automatic machine. Tools are made of tool steel, extrusion punch is designed of 19 550.4 steel, extrusion die is designed of 19 436.4 steel and extrusion die´s band is designed of 19 733.4 steel. Tools are designed to be improved by hardening and drawing.

Bulk forming technology of shutting nut
Votavová, Jitka ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
VOTAVOVÁ Jitka: Bulk forming technology of shutting nut. The project elaborate in frame bachelor studies submit design technology of production shutting nut by means of bulk forming from stteel 11 320 5R CSN EN 10 204. Production sequence was proposed upon linear analyse of bulk forming especially to extrusion and upsetting. Technological calculations was made. Maschine was select automatic transfer press TPM12, nominal power 2000 kN (producer SMERAL Brno). Extruder will make from tool steel 19 436, clamp ring from tool steels 19 733 and extrusion die from sintered carbide SK65. Heat-treatment extruder and clamp ring according to drawing.

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.
