Production of socket wrench
Kryštof, Marek ; Forejt, Milan (referee) ; Císařová, Michaela (advisor)
This thesis propses the design of production of a socket wrench. A socket wrench is used as safety wrench for loosening safety screws of the car wheels. The proper technology for production was chosen based on the component requirements. The component is made by using metal extrusion and heading. The starting blank for metal forming was chosen steel rod made of 1.7131 steel (ČSN 14 220) with a diameter of 26 milimeters. The safety wrench will be made by doublecrank press GTX-300H. Production will be done in three operations.

Manufacturing of a connecting pin by cold forming
Koumar, František ; Peterková, Eva (referee) ; Jopek, Miroslav (advisor)
The diploma thesis is focused on the optimization of the production of a rotary connecting pin, produced by bulk cold forming with a focus on upsetting and forward and backward extrusion. The resulting pin will be made of 1.4511 steel. From the three proposed variants of production processes, the optimal variant for four forming operations was selected. Extrusion tools are made of tool steel 19 830. A numerical simulation was performed to verify the suitability of the sequence of the selected variant. The size of the production batch is set at 700,000 pieces / year. In the technical and economic evaluation, the calculated production price of 1 piece of part was coMPared between machining and volume forming, at which the production costs amount to CZK 6,64. The return on this method, with an assumed profitability of 10%, was found for 568 182 pieces produced.

Bulk forming technology of carrier pin
Večeřa, Jiří ; Samek, Radko (referee) ; Forejt, Milan (advisor)
This thesis deals with a proposal of a technology for manufacturing a carrier pin made of corrosion resistant chrome steel 17 021.3. Having studied the information about cold bulk-metal forming in the available literature, I have suggested two variants of manufacturing processes. The suggested manufacturing variants consist of four forming operations which combine upsetting and extrusion. As far as the chosen variant is concerned, there have been made technological and strength calculations for the individual operations. As regards the designed technology, I have opted for the automatic multistation forming machine TPZK 25, produced by the company ŠMERAL Brno.

Bulk forming technology of connecting pin
Trnka, Filip ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The project elaborated in frame of engineering studies branch M-STG proposes a technology of connecting pin – structural steel 11 320 5R. The technological calculations were performed and the production procedure was devised on the basic on the literary study of cold bulk forming with concentration on the extrusion and upsetting. Forming machine was design HATEBUR BKA-3 with a nominal power 1800 kN. The component is made in four forming operations. Extruder will be made from tool steel 19 830, extrusion die from tool steel 19 830 and clamp ring from tool steel 19 740.

Manufacturing of swivel pin
Vávra, Roman ; Šlais, Miroslav (referee) ; Řiháček, Jan (advisor)
The thesis deals with the design of a suitable technology for serial production of a pin. The component material is structural steel 11,320 5R. Due to the series production and material savings, the molding technology was chosen to be cold. For production, the CM 4-5 ECO HATEBUR process press was designed with a nominal force of 1 700 kN. Progressive tool and drawing documentation of tools for the final operation were also designed. The tool load was verified by manual calculation, and the finite element method was calculated to heat the formed blank due to molding.

Production of pinion
Vališ, Ondřej ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
The bachelor thesis deals with literature study of cold forming technology. Further the thesis submits a proposal of the production technology of pinion into the gearbox of passenger vehicles made from alloy steel according to ČSN 16 326. Thanks to knowledges aquired by literary study of bulk forming issue was suggested a direct extrusion technology with consequential cold upsetting. The component part will be produced in two production processes and series of fifty thousand pieces per year. These manufacturing processes will be used on forming machine called Schuler with nominal force of two thousand tons which is part of Metaldyne Oslavany company involved in automative industry.

Production of high pressure hydraulic filter housing
Podloucký, Lukáš ; Lidmila, Zdeněk (referee) ; Císařová, Michaela (advisor)
The Bachelor’s thesis is focused on solving the problem of production of high-pressure hydraulic filter by cold extrusion technology. The initial semi-finished product is a C15R steel cap with a diameter of 104 mm and a height of 57.9 mm. The production series assumes a quantity of 30,000 pieces per year. The technologicality of the product evaluation was based on technical literature knowledge and professional experience. The technological process was chosen subsequently. This process counts with the extrusion in two operations with mid-operational recrystallization annealing and with the use of surface treatment by phosphating and soaping. An Eitel 1 250 press with a nominal forming force of 12 500 kN is designed for the production. The design of the forming tools takes into consideration the shape of the extrusion, technological principles and mathematically verified safety. The material of the die and punch is high-speed tool steel 19 830. The material of the ejector it is high-alloy tool steel 19 437. The technological process and force calculations are verified by simulation of the forming process created in the Simufact Forming program.

Buffer box of a wagon
Řezáč, Patrik ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The subject of this work is the proposal of a technological process to create a train car bumper using volume thermoforming. The S235JR (11375) steel has been chosen as the main material. The work contains technological calculations, blueprint documentation of the mold, of the tool and a proposal of the set of machines for the production line. The capacity of such production line has been calculated to be 12460 pieces per year. Economical-technological evaluation of the production is also included.

Productin of injector holder
Štys, Michal ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
This paper presents a design of the production process for the clamping nut by cold extrusion. The nut, which is made of material ČSN 12 050, is used to clamp the injection nozzle to the injection system. Subsequently different variants of production were processed, from which the variant B was chosen. For slug a rod with diameter size of 24 mm with toleration f9 made by the company Ferona a. s was chosen. Calculations of process parameters were made for this variant. Based on the parameters the automatic forming machine TPD 630 with nominal force of 6 000 kN was chosen. For the selected machine, operational tools were designed for each forming operation, whose geometry is shown in the drawing documentation. Based on the technical and economical evaluation, the final price of the formed part was set at CZK 18,48.
