Manufacturing of pin with flange
Procházka, Pavel ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The bachelor thesis is focused on the design of the towing hitch, which is used in the tractor. The component will be the production of a die forging technology made of low-alloy steel 13 242. The material is supplied as hot-rolled bars with a diameter of 60 mm and a length of 6 000 mm. The size of the production series has been set at 25,000 pieces per year. Due to the issue and the size of the forging, the component will be made on a power hammer. The machine Šmeral KHZ 8A, appears to be a suitable machine as the forging work was calculated at 89 kJ. The technical - economic evaluation takes into account material costs, which amount to 1,364,271 CZK. The die is made of tool steel 19 663, its purchase price is 73 000 CZK.

A design of small size power hammer
Hladík, Radim ; Knoflíček, Radek (referee) ; Tůma, Jiří (advisor)
The bachelor's thesis, in addition to the design of small power hammer, contains information from the history of power hammers, current research of the market of the manufacturers of these forming machines and their specific requirements. It also states the classification of these forming machines according to various criteria for example based on the structural arrangement, the method of energy transfer, etc. Furthermore, two designs of the power hammer construction are carried out according to the specified parameters. One of these variants is selected based on the multicriteria analysis and presents a detailed proposal. In this selected variant is made 3D model design sketched using software Autodesk Inventor 2021, basic design calculation and drawing documentation. In conclusion, there are recommendations for practice and evaluation of work results.

Design of wheel hub production
Zahálka, Tomáš ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The subject of this thesis was to propose a possible way of production for a wheel hub on the front axle of VAZ 2101 made out of steel 12 050. Based on the accesible technologies was selected a volume thermoforming technology, specifically drop forging for its positive impact on mechanical features of forging. Construction of the die cnforms to the norm ČSN 22 8308 with closed spout groove. The forging is done by a hammer KHZ 8A, with an impact energy of 80 kJ. Dies, upper and lower, made of tool steel 19 552, tempered to 54 HRC.

Machines for forming technologies
Kvapil, Jan ; Henzl, David (referee) ; Podaný, Kamil (advisor)
The Bachelor thesis, which is developed in an undergraduate degree in B 2339, provides a brief overview of the various types of machines used in metal forming. The work is characterized by earlier today and used machines. The basic types of machines include: mechanical presses, hydraulic presses, hammers and rotary molding machine. All machines are described operating principles and their practical application.
