Technology of thrust bearing steel cages production
Jež, Marek ; Štroner, Marek (referee) ; Rumíšek, Pavel (advisor)
JEŽ Marek: Technology of thrust bearing steel cages production . Diploma assert of daily magisteral´s studies, study programme – Industry. The branch manufactoring technology, 2 end form, level 2 – summer semester, study group 50 / 51, academical year 2007 / 2008. FSI of Brno University of Technology, department of forming and plastics, May 2008, 78 pages, 54 pictures, 6 supplements. The main theme of the Diploma Theses is the technology of production of tin cages for axial spherical-roller bearings. The given matter includes the production of tin cages for axial spherical-roller bearings – by traction, cutting, punching and calibration. For the chosen representative, i.e. bearing with marking 29 336 M I suggest the substitution of tin cage instead of the brass one. The component (cage) is made of the sheet iron 11 300 of 4 mm thickness, the basic semi product is the sheet panel with the size of 360 x 4 x 3000 mm. In solving the given matter, it is started from the fact that the current state of the cage is still under development. The aim of the Diploma Thesis is to choose the representative, suggest the appropriate technological progress, proposing the engineering design of functional parts of the tool for punching the holes/windows including the necessary calculations and workshop graphical documentation.

Production of forging piece "Spanner"
Vávra, Jan ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
Projects developed within the bachelor's degree in Mechanical Engineering, presented a proposal technology forged wrench - the hot-rolled steel bars 11 523.0. The thesis also compares the past with conventional methods of production and considering the new technological process of manufacturing. Based on the literature studies about fitting and calculations, was chosen to die forging hammer KHZ 2 A (producer ŠMERAL Brno, plant Hronov), with nominal energy of 20 kJ working pressure of 16 MPa and 30 kW electric power.

Manufacturing of Shaped Holes into Stamped Metal Sheet
Bartusek, Břetislav ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The aim of bachelor thesis is a proposal of a new technology for manu-facturing of shaped holes into stamped metal sheets. The sheets are made of stainless steel DIN 1.4301 of thickness 0.8 mm. Square holes will be punched into a half-finished metal sheet with pre-pressed lengthwise stamps where elastic-plastic deformations occur. On the basis of study of the sheet metal forming technology, technological calculations and the machine adaptation, a new technology is proposed. The new technology is unassuming both with respect to machinery and tool equipment in a mechanical engineering factory. Also it enables solutions of dimensionally variable die stampings with stamps in higher quality for minimum costs. As the forming machine a punching press, model LDR 25-A, was chosen.

The Issue of Trimming and Punching of the Forged Piece
Kopečný, Adam ; Šlais, Miroslav (referee) ; Řiháček, Jan (advisor)
The bachelor thesis deals with the design of tool for punching and trimming of the forged case, made from 14 331 steel. Forging will be done on forging press LMZ 1 000 made by Šmeral Brno, a. s. The dies are made from 19 552 steel. Production series is 520 000 pieces per year. The tool is designed as progressive. Simulation of the forging process in FormFEM software has been done, because of evaluation of the trimming and punching temperature. Based on calculated punching and trimming force the press S 160 E made by Šmeral Brno, a. s., was chosen. Piercing punches and dies are produced from instrumental steel 19 550, with heat treatment according to design documentation. To conclude, the economical evaluation was done. The bachelor thesis was done in cooperation with Šmeral Brno, a. s.

Technology of the frame base production
Havliš, Lukáš ; Špaček, Jindřich (referee) ; Rumíšek, Pavel (advisor)
The bachelor's thesis deals with technological project of frame base production. Since a component designated as a wing base is produced together with this base, the thesis is also concerned with production of this part. Methods of sheet metal forming are analyzed in the theoretical part. Methods used during production pressings - such as cutting, bending, punching and calibrating – are concerned. Practical part of the thesis comprises description of produced segments and their location and function within the assembly, choice of material, shearing layout and choice of forming machine. Economic evaluation of segments production has been performed in conclusion. As soon as material has been chosen (11 343 material has been chosen with regard to low requirements for assemblies), calculation of cutting and bending force has followed. Forming machine (LE 250 has been found the most suitable one) has been chosen based on results of the necessary forming forces, after evaluation of cutting layout and demand on the sheet metal coil. Two options of components production have been compared in the economic evaluation. Method of production in a common tool has been found more cost-effective.
