Produstion of shifting carrier by solid forming
Stříbrný, Jan ; Štroner, Marek (referee) ; Kopřiva, Miloslav (advisor)
The Project elaborated in frame of bachelor's studies branch 2303 and it presents technology design and forging production - part of aluminum alloy EN AW 6082 T6. Drop forging in one operation was suggested on the basis of specialized studies on the subject of drop forging and calculations. Regarding urgent need use of ejector pins and other aspects, he was elected vertical forging press LZK 1000 P / SH (producer ŠMERAL Brno), with a nominal force 10 MN. Swages are made of alloy instrumental steel, 19 552.8, heat-worked according to drawing-documentation.

Production of holder by solid forming
Nejedlý, Petr ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The project elaborated in frame of engineering studies branch 2307. The project is submitting design of technology production of holder by solid forming of steel 12 020.0. Pursuant to of the literary pursuit a problem of die forging and calculation was designed forging on a vertical cranked press LMZ 1600 and with nominal forging force 16MN (producer ŠMERAL Brno). The lower ejector is using for extrusion component.Heating billet is accomplished by using induction furnance type SOP 400kW.For trimming is used trimmning press LKOA 200 with force 2 MN. For holding of dies is used holder QLZK 1600/UC, dies are made of instrumental steel 19 552.9. A part of this project is economic estimation of production and produce of manufacturing drawings.

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.

Issues of drop forging on presses
Jelínek, Tomáš ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
This thesis is focused on the issue of drop forging on presses. The power forming machines works with calm pressure of the forging part. Their main disadvantage is the forging of the slag layer into the product. Hydraulic and mechanical presses are used for drop forging. This technology is mainly used in series production in most industries. To achieve a quality forging is necessary proper heating of the semi-finished product to the forging temperature. This reduces deformation resistance, tool wear and the required forming force The design of the forging is based on the drawing documentation of the required part. The shape of the product is driving for the dividing plane, the size of the stock, the permissible geometry deviations and tolerances. It is also necessary to take into account the flash groove, the clamping of the dies and the type of ejector. There are many companies in the market that deal with die forging. For clarity, several of them are listed, with an overview of the machine and production portfolio.

Drop forging of hub
Vostřel, Jan ; Novotný, Karel (referee) ; Štroner, Marek (advisor)
The project elaborated in a frame of Bachelor’s studies branch B 2307 presents a technology design of a forged piece – hub – a part of a gear box made by drop forging from 14 231.0 material. Drop forging in three operations was suggested on the basis of specialized studies on the subject of drop forging and calculations. Assumed series of 40 000 pieces a year, preciseness and automatization of production of the part, will be produced on the crank drawing inclinable press LMZ 2500 (producer Šmeral Brno, a.s.) with nominal tensile force 25 MN. Swages are made of alloyed instrumental steel 19 552.8, heat-worked according to drawing documentation. At the end of the project technical economic evaluation of the technology design is implemented.
