Technology of extrusion
Cháma, Jakub ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
This bachelor thesis is a literary study dealing with extrusion technology and is aimed to be used as a study material. There are described basic principles of technology, the division of methods, used materials, machines, tools and the area of usage. The main focus of this work is to depict advantages and disadvantages of extrusion technology and its application in practice, which is supported by the example of usage in one of the Czech companies called Vítkovice Cylinders.

Bulk forming technology of grooved charge
Sklenář, Luděk ; Samek, Radko (referee) ; Forejt, Milan (advisor)
SKLENÁŘ Luděk: Bulk forming technology of grooved charge. The project prepared as part of the Master-degree studies in the Manufacturing Technology and Management in Industry, concerns the technology design for manufacturing a grooved charge by cold bulk forming. Grade 12 040.3 (CSN) steel was used as the initial material. For the batch of 50,000 pieces per year are proposed three alternatives. The chosen option No. 1 is made of technology and tensile strength calculations for metal forming operations: upsetting, backwards extrusion, forward extrusion and calibrating. The grooved charge production is designed for two forming processes that will be realised at the Colombo press Agostino, which is part of the machinery park company Metaldyne Oslavany. The extruding dies for the manufacture are made of tool steel 19 655 and tool steel 19 830 is designed for extruding punches.
