Machinery used in an open die forging
Novák, Libor ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
For production of components, which are made by open die forging, are used forging hammers and hydraulic presses. The project contains a dividing of machines, short description, advantages and disadvantages and using of concrete types of forging hammers and hydraulic presses in practice. Advantages of forging hammers are simple construction, high range of choice from many types and simple maintenance. Disadvantages are big shakes and danger of accident. Forging hammers can be chosen from spring, pneumatic, hydraulic and steam air types with or without acceleration. Hydraulic presses are divided into push -down presses (two and four - column presses) and pull - down presses (two and four - column presses). Advantages consist in simple operating and controlling via computer. Disadvantages are complicated construction and difficult maintenance.

Suggestion of technology for manufacturing parts of a hydraulic press
Gryc, David ; Mouralová, Kateřina (referee) ; Zemčík, Oskar (advisor)
An introduction of hydraulic press and description of his main parts. An analysis of the given components and a proposal for the most suitable intermediate was made. A selection of tools and gauges for individual operations has been done. A proposition of manufacturing process and enumeration of machines times was proposed. Economic evaluation containing costs for intermediate, tools, workmen’s wages and energy for operating machines has been calculated.

Modification of columned hydraulic press
Pospíšil, Lukáš ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This bachelor’s thesis is focused on structural modifications of the universal columned hydraulic press. The thesis proposes justifiable structural modifications of fundamental parts of the press, including material choices, and necessary calculations and simulations of material strength and deformation characteristics. Calculated specifications of the unit that powers the press are also presented.

Production of trailer wheel shaft cover
Vaculík, Lukáš ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
The project elaborated in frame of bachelor´s degree program B-STG (“Mechanical Engineering Technology”) evaluate production of trailer wheel shaft cover, with the volume of productions 25 000 pieces for year. The cover will be manufactured from deep-drawing steel ČSN 11 305 (DC 04), surface will be blackening. On the base of literary studies and process calculation was designed manufacturing process. Production will take place in eight operations, the main operation is executed with conventional deep drawing proces. For the towing operation was choosen hydraulic press AMOB PH 25T. Upward drawing die with blank holder Was designed next, which is adapted for ejected press. Finally, price component and a profit from production have been calculated.

Manufacturing of the engine oil tank cap
Polášek, Lukáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The project introduces a technology design of an oil tank cap manufacturing for a turboschaft engine TV3 – 117MT of the MI – 17 helicopter. The component will be produced of DC04 material in a batch of 10 pieces per year. Based on the evaluation of possible production methods the rubber pad forming process with an uncertain instrument (Guerin Method) was chosen. A raw material of 112 mm diameter will be cut out from a metal sheet which dimension will be 1000 mm x 2000 mm x 1 mm. An versatile (universal) tool which is suitable for forming, cutting and bending is designed for a hydraulic press machine CTH 1000. It`s power is 10 000 kN and it is available in the Arial toolshop.

Production of the shape cover
Žilka, Daniel ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
This thesis deals with a project for production of output shaft cover for agricultural technique which is made of deep drawing steel DC04. On the basis of component geometry, material and contract volume (10000 pieces per year) the drawing technology without wall attenuation has been chosen. A production plan has been processed for this technique. Drawing will be realized within four operations in a modularly solved tool in double-acting hydraulic press Ždas CTH 250. A die design is a part of the thesis, the drawing tool for the first operation is described in detail. Within economic assessment a product price is counted and contract profitability is evaluated

Workshop hydraulic press
Budík, Tomáš ; Tůma, Jiří (referee) ; Omes, Jiří (advisor)
This work deal with workshop hydraulic press to moulding heated rod blanks with the possibility of adjusting the main pressing cylinder depending on the operating technology. We analyze issues of design and calculation of the hydraulic circuit and the hydraulic, electrical and electro-hydraulic components. In the end we solve the elastic deformation analysis of the machine using the finite element method.

Design forming tool for production of cylindrical case
Fiedor, Pavel ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The project was made as a part of a bachelor’s degree study program B-STG and it proposes the concept of a molding instrument for the making of a headless bushing. The making of the given part consists of 3 operations, including widening by means of a hard instrument and flanging. The instrument is fastened into a hydraulic press CUPJ 60/10. The cutting method is used in order to prepare the semi-product. The aim of the bachelor’s thesis is to propose a technological procedure of making and processing of design documentation of an instrument for making a headless bushing.

Hydraulic press of current production
Kolbábek, Lukáš ; Matějka, Petr (referee) ; Blecha, Petr (advisor)
In this thesis the background research is performed and a description of the basic parameters and parts of hydraulic press of current production. The advantages and disadvantages of hydraulic press are compared over the mechanical press. It deals in detail with constructional and technological division of press. The individual uses are described for the technology of sheet metal forming and solid forming metal materials where specific manufacturer and type of press are indicated. It further describes the new trends in use of press for production of car body parts in the automotive industry. In conclusion the basic formula for the design of the press are outlined.
