Mechanical press 12 500 kN
Buyalskiy, Alexandr ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
This diploma thesis deals with the design of a mechanical press drive. It is a crank press with 4 points. The machine is designed for surface forming of body parts in the automotive industry. The mechanical press can work both in the mode of individual strokes and in automatic operation with the equipment to the production line. The first part deals with an analysis of forming machines and a description of the main parts of the press. The second part deals with the design of the drive based on the specified parameters. This part includes a calculation of the individual sectors of the press and a strength check of the drive parts. The drawing documentation is included.

Slide adjustment of mechanical press
Novotný, Ondřej ; Pavlík, Jan (referee) ; Omes, Jiří (advisor)
The bachelor's thesis deals with the design of a slide adjustment of mechanical press for double-point mechanical press with nominal force 3150 kN. This thesis also includes the design of the kinematic diagram of the slide adjustment, design of the pressure point and drawing documentation. First part of the thesis is focused on the problematic, especially regulation of shut height. Next chapter is about overload protection, which is important for properly and safety working proces. I the second part, there is created kinematic mechanism and design of pressure points which are made in Autodesk Inventor Professional 2017. Last chapter includes valorization of pressure points design. The pressure point with the most advatages is chosen for the final slide adjustment mechanism. For the final mechanism is made a calculation and drawing documentation.

Press LKJP 250
Dvorník, Milan ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
This Master thesis deals with the design concept of press drive of LKJP 250 press with planetary gearbox. It is a single one-point crank universal press, which is designed for cold-forming operations. The press is used for operate in single stroke mode or continuous operation when engaged in an automatic press line. The first part of the thesis deals with the research in the field of mechanical crank press drives arrangement and kinematic analysis, followed the description of the main parts of the press drive. The second part of the thesis deals with the design of the press drive. The solutions are suggested in several possible options with performing basic calculation. On the basis of the required criteria, the most suitable variant is chosen, for which detailed design and control calculations of individual design nodes of the press drive are performed. Part of this thesis also includes the required technical drawing documentation of the mechanical press.

Moving bolster of body panel press
Novotný, Lukáš ; Tůma, Jiří (referee) ; Omes, Jiří (advisor)
This Master thesis deals with design structures of moving bolster for body panel press and with design of railroad tracks, in which the bolster is moving in two mutually perpendicular directions. These moving bolsters are used for facilitating and speeding up the change of pressing dies, which is desirable in automated automotive industry for shortening and streamlining the pressing die change. The part of the work is research of the current state of knowledge in systems for quick die change, design of the moving bolster and its drive, design of railroad tracks, amount of design and control calculations, design of mechanism for lifting the bolster, optimization and strength calculations of bolster in ANSYS software. All the design structures of bolster, railroad tracks and basic workplace layout are processed in 3D software for modelling Autodesk Inventor. Attachments consist of drawing documentation of main assemblies, namely mounting drawing of moving bolster assembly, mounting drawing of railroad tracks assembly, drawing of workplace layout and furthermore drawing of driven shaft, weldment and workpiece of moving bolster and railroad tracks block.

Press LKDS 800
Kolbábek, Lukáš ; Sláma, Jaroslav (referee) ; Omes, Jiří (advisor)
The present Master´s thesis deals with the concept of press drive of Blanking press LKDS 800 used for blanking in automatic blanking line. The first part of the thesis is dedicated to the individual arrangements of press drives and servo press drives and to the description of main components. The second part of this thesis deals with the structural design of the drive. Based on the computation of the crank mechanism, several design solutions were suggested. From these solutions, the option with the lowest drive height is selected. This option, offers the computation of the main drive, flywheel, spur gearing and clutch/brake combination. This computation is followed by computations of individual construction nodes, which include a design and dimensioning of the individual joggles, shafts and bearings. The drawing of the press and clutch shaft assemblies with a list of items are also included.

Crank press 250 with direct drive
Čupr, Pavel ; Pavlík, Jan (referee) ; Omes, Jiří (advisor)
This thesis deals with the design of the single point crank press with direct drive. This crank press has an O-shaped stand and an access to the workspace from two sides. The introductory part of this paper describes the principles of mechanical presses drives, drives arrangement presses with direct drive and some conceptual solution stands. The main part of this work is a calculation of basic drive parameters of the press. There are suggested three design variants. The design with the smallest space requirements and good accessibility to the press working space was chosen. The calculation of the main shaft, the input shaft to the planetary gearing and calculation of brake sizes and the planetary gear to the bend and tough was done. Part of this thesis also includes technical drawing of the assembly press, technical drawing of the drive press, technical drawing of the stand a technical drawing of the satelitte gearwheel.

Presses with direct drive of current production
Bajdich, Matej ; Dokoupil, Vladimír (referee) ; Omes, Jiří (advisor)
The aim of this work is to analyze to the issues of mechanical presses with direct drive, their comparison with mechanical presses driven with indirect drive and introduction of presses with direct of current production on the market. In the first part of bechalor's thesis, it looks at the basic information about mechanical presses, the division of mechanical presses and describes the current state of selected mechanical presses on the market. In the second part, the works deals with the calculation and design of direct and indirect drive according to given parameters. 3D model of drive is created from the design of direct drive. To the part of the 3D model, the brackets for attaching the servomotor to the press body, production drawnings are attached. The last part of the thesis deals with the comparison of results from the second part of the thesis, the evaluation of the diferences between the direct and indirect drive of the mechanical presses resulting from the first part of thesis. Last but not least the author's view when comparing the drives and the idea of the next development of the direct drive technology in mechanical presses.
