Production Possibilities of Press Brakes
Hrazdíra, Michal ; Jopek, Miroslav (referee) ; Řiháček, Jan (advisor)
The bachelor thesis deals with the production possibilities of press brakes. This is a literary research, in which the aim of the work is to describe the principle of bending. It also focuses on common and special tools and their use in engineering practice. The first part of the work is focused on general bending technology, which discusses the basic principles and possibilities of this method. The main chapter is the bending itself, where the individual types of machines, their components, tools and clamping systems are introduced and described. Furthermore, modern tools and their application in engineering practice are presented. In the last part, the production of the switchboard cabinet is presented on a CNC press brake.

Technology of Production single parts with multiple bend
Daňhel, Marek ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
DAŇHEL, M. Production Technology for Parts with Multiple Bends. Bachelor thesis, Combined form of bachelor degree programme ENGINERING, subject of study Manufacturing Technology, 1st form, 3rd year of study, academic year 2008/2009, study group 3K1. FME BUT Brno, Institute of Manufacturing Technology, Department of metal forming and plastics. No. of pages 47, pictures 32, tables 6, supplements 9. Bachelor thesis supervisor doc. Ing. Milan Dvořák, CSc. _______________________________________________________________ The project developed within the framework of the bachelor degree programme, subject of study B2307-00 Manufacturing Technology, submits a bending technology proposal for a part with multiple bends. The bachelor thesis presents a theory overview related to the forming operations comprising bending, a selection of suitable alternatives for the manufacture of the given part and the production sequence for this part. The design of the bending tool is made in accordance with valid engineering standards for forming operations. As the basis for production the project includes manufacturing drawings of the punch and lower die and the drawing of the bending tool assembly. Technical and economic evaluation and conclusions in respect of the proposed technology constitute a part of the project.

Safety Equipment for Motorcyclists
Všianský, Michal ; Svítil, Petr (referee) ; Zdařil, Zdeněk (advisor)
In my thesis I looked for a solution to simplify the transfer and storage of motorcycle helmet. This is the helmet for smaller motorcycles for city traffic, where isn ´t often the sufficient space for helmet storage after the motorcycle is left. I choose this topic because the motorcycles are one of my main hobbies and I know how unpleasant is to move in the city, school or work always with the helmet in your hand because you cannot put it into your backpack or to the standard personal cabinets at school cloakrooms or in the factories. The helmet which I made will reduce its volume by folding approximately about 40% and it makes easier the transfer and enables putting into the storage space, cabinet or hand luggage /backpack, bag/ - as I know acc. to my experience the bikers carry with them. The skeleton and the helmet cushioning is divided into four parts /upper, two side and back/ which enable the folding. The cushioning of the side parts will fill the inside space of the upper part by simple folding, then the side skeleton will be inserted to the upper two-case part and in the last – back part, fixed to the rest of the helmet by the hinges, will fold into the helmet – it covers the above mentioned cushioning of the sides and so it protects its damage. The whole will be fixed by the tightening bend which is also used for helmet fixing on the head. In the dismanted status is everything saved by the locks which connect the back and side parts. The helmet skeleton was made of kevlar which compensates the added weight and also keeps the sufficient solidness. Because of double case enabling the saving of the side parts, the solidity and also the safeness are bitter then by using of normal helmet. The helmet shape is created in easy concept and aerodynamic shape. All details, blending and surface extrudation have the reason. In the bottom is the material enlarged because of locks , in the middle part the enlargement is used for breaking of hanging sides and the cleats on the outside enable the cooling and head airing. For the thesis presentation I make the model 1:1 which cannot be fold up. The skeleton is made with the help of 3D printing and after that colour treated. The cushioning milled on CNC machine of extrude polystyren will be refilled by soft foam and covered by the cloth. The shield protecting eyes will be vacuumed of colourless plastic.
