Manufacturing of mudguard holder using forging technology
Ondráček, Miroslav ; Podaný, Kamil (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with problems of drop forging. A detailed literary study is prepared in this work, in which there are data for working out the specified component – mudguard holder. There are options for cutting the semi-product, types of lubricants, construction of ideal preform or different kinds of forging machines for drop forging. The next part of this thesis is about technology of drop forging on crank forging presses. This section is aimed on technical drawing of the forging and its classification by the complexity of the shape. Furthermore, the thesis deals with the economic part, setting out the individual costs of the production from which the cost price of a forging is determined.

Design of robotized workplace for die forging
Krejčí, Radek ; Zavadil, Radek (referee) ; Podaný, Kamil (advisor)
The thesis deals with the design of technology for production of wheels to be manufactured by die forging 15 142 low-alloy steel at an amount of 500,000 items per year. Based on a consideration of the suitable methods of manufacture, die forging on a Jing Duann FP-1600G vertical forging press was chosen as the best, as documented by the necessary technological and design drawings. A die with inserts made of 19 552 steel was designed for this machine. In view of the volume of annual production, a fully automated workplace was designed consisting of three robots and a chain and pan conveyor. In the conclusion there was a technical-economic evaluation of costs for the material of the semi-finished products and price of dies for annual production.

Drop forging of pinion
Cvrček, Jan ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
The final project has been elaborated in a frame of Bachelor’s studies branch Manufacturing technology assesses design of production pinion by method of die forging. The pinion is manufactured from alloyed structural steel 14 220 (1.7131). Size of production is set on 100 000 pieces per year. The pinion will be forged on the vertical forging press LMZ 1000 A with forming force 10 MN. The forging is formed in two operations. Forming tool is manufactured from alloyed instrumental steel 19 552 (1.2343). In the last chapter of the project is described the price comparison and costs for manufacture of die forging and machining.

Forging of the "lock-bolt"
Frýdl, Pavel ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
To lock-bolt manufacturing was selected technology of die forging. Lock-bolt is made of 11375 steel in a series of 2700 pieces per year. With the use of literary studies and practical knowledge has been developed technological process fittings. It includes the draft instrument stainless steel 19663 including drawings. Forging is performed on a hydraulic-pneumatic hammer KJH 2 with a nominal value of 20 kJ impact work. Blanks are cut from bars 30 mm 6 m long to bars 52.2 mm long. The techno-economic evaluation shows that the price of a forging is 4,71 CZK and for production will be need 24 pieces of bars.

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.

Forging oblong forgings
Příkaský, Jakub ; Štroner, Marek (referee) ; Lidmila, Zdeněk (advisor)
The project deals with the design of the production of a rod-shaped component using a die swage. The material is steel 12 060. Based on a literature study on forging and calculations, the forging, the technological process and the hammer die were designed. Based on the calculated work required, the power hammer KHZ 2 was designed. Technical and economic evaluation was performed.

Production of the piston rod eye
Vahala, Jiří ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
The project deal with technology design of production of the piston rod eye from steel 11 523 in the amount of 30 000 pieces. From various possibilities of technology was chosen as the most optimal method the technology die forging. Pursuant to the study of literature and calculations there will be made the forging as a double-edged in single-cavity die on hammer witch several hits in finishing hollow. According to the calculated energy there was selected pneumatic-hydraulic hammer KHZ-4A witch stated energy of 40kJ. The tool was made of steel 19 552, heat-treated according to the drawing documentation. The technical and economical evaluation was focused on the total material cost of the semi-finished material and the cost of manufacturing forging die, which is 1 229 507 CZK in total.

Sinumerik tools for programming of CNC machine tool
Chytil, Tomáš ; Sámelová, Vendula (referee) ; Polzer, Aleš (advisor)
The bachelor thesis focuses on the usage of possible ways of the Sinumerik system for programming of the form of the drop forging. The first part of the thesis contains of the characteristics of the part and its function in the composition. In the second part there is all the proper visual documentation. The following parts of this piece of work is devoted to the history and specification of the Sinumerik control system and a suggestion on how to make a forging die.The next part is contributed to the possible ways of how to produce a form in the Sinumerik system. The final part deals with the very formation of the programme and its graphic simulation.
