Production covering grids of welding machine
Rous, Miroslav ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
This thesis has been written in the time of my bachelor studies and it describes a production design of a rear cover of a welding set. It focuses on manufacturing of ventilating holes in this component. The cover is made of steel of standard quality 11 320, 1 mm thick. The flattened out shape of the component will be stamped on a Finn Power SG6 machine and subsequently it will be bent on a press brake Safan DNCS 225-4300. The practical part of this thesis contains a design of an instrument making the ventilating holes and an economic assessment.

Production of IT case
Holub, Dominik ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The master’s thesis deals with proposal of technological process for production of computer case in EMKO Case a.s. Computer case is manufactured from a DX51D + Z275 steel sheet with thickness 1 mm. For manufacturing were chosen technology punching and press-brake bending as the best technologies. Master’s thesis contains literary studies of these chosen technologies. Based on literary studies were made technological calculations, proposal of technological process and choice of machines. For punching was chosen machine TRUMPF TruPunch 2000, for press-brake bending hydraulic machine TRUMPF TrumaBend 50V. For chosen solution is made technical and economical evaluation.

Production Possibilities of Punching Machines
Dolejš, Radim ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
This thesis introduces the elementary principles of punching, stemming from the gradual shearing theory. Furthermore, it includes description of instruments used in cassette and revolver systems. Forming tools are then also defined. The thesis details the parameters of individual parts of the punching machine, and an example of a hybrid laser-punching machine is then presented.

Punching technology
Králíček, Václav ; Harant, Martin (referee) ; Peterková, Eva (advisor)
The thesis is focused on punching technology, technology which can create complex-shaped parts from sheet metal. The thesis contains description of the principles of punching, emphasis is put punching tools and various production methods, which can be performed using modern punching machines. Part of this thesis is focused on comparison between punching technology and laser cutting. The comparison is shown on two different semi-finished products made from stainless steel by ACO Industries k.s. These semi-finished products are compared from the point of view of production accuracy and manufacture speed.

Selection of appropriate technology for the production of welded constructions of boiler JE 12 and JE 6
Janás, Milan ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
The diploma thesis on the selection of appropriate technology to produce the welded construction of electric boiler JE6 / 12 aims to evaluate available production technologies and choose the most suitable of them. Choosing the technologies focuses primarily on those that are available at Slokov. Due to the connection of the welding robot to the production, it is necessary to consider the overall connection of the production and the high accuracy of the production. The individual methods of production, material separation, welding, bending and surface treatment are first theoretically analyzed and their advantages, disadvantages and parameters are summarized. Subsequently, it is practically tested individual technologies for a representative part and it evaluates the achieved parameters and economics of production. With the results obtained, the most suitable technologies are selected. With the selection of technologies, there is a need for a change in design and production parameters. Changes and modifications to the design describe another point. To achieve maximum efficiency and quality of production, a welding robot is used to make welds. The description of the production, modifications and overall design of the robot describes the next point of this work. The last part summarizes the economics of selected production technologies and details the technological process. The aim of the thesis is to design such technologies that will be advantageous from the point of view of the economy and from the perspective of the available possibilities of the company.

Production of supporting plate
Filip, Jiří ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of technology for production of supporting plate, which is a top part of a service trolley, serving for manipulation with switch of high voltage. The supporting plate is manufactured of low carbon, deep drawing steel DX51D+ZM thickness 2 mm and quality according to EN 10346. Annual serie was set for 200 pieces. In evaluation of production possibilities were chosen technologies of punching and bending. There was designed unfolded shape of the sheet metal with dimensions 1068 x 900 mm and created cutting plan. As was found, from one metal board is possible to cut out 2 pieces of the supporting plate, while 70% of material use. In the next step, punching tools were chosen and manufacturing process was made. The highest achieved cutting force was 122,8 kN. The chosen machine is hydraulic CNC press TruPunch 5000. For bending there was created a bending plan, according to which bends will be made in thirteen steps. Used bending tools are punch OW209/S and two types of matrix EV005 + FWZ and EV006 + FWZ. Maximal achieved bending force is, according to the calculation, 259,8 kN. Bending operations will be made on CNC press TruBend 5130. In a technical and economical evaluation was determined cost for the material, which is 57 337,5 Kč.
