Optimization of production process of drain
Staněk, Vojtěch ; Chudík, Ivan (referee) ; Podaný, Kamil (advisor)
The project looks for a solution to optimalization of rotational deep drawn part with flange production. It deals with sewerage drain, which is produced by conventional tool to two deep drawing operations. The used material is austenitic Cr-Ni stainless steel 1.4301. Suitability of this material for deep drawing operations was considered by means of the tensile test and the Erichsen test. On the bases of these results, serializability of production and theoretic relationships for determination of number of deep drawing operations, it was decided upon one operation serial production, by conventional tool without attenuation thickness of sheet. Production will take place on hydraulic press Dieffenbacher PO250 with magnetic tool fastening. The deep drawing tool was designed and constructed. For series of 2 000 units per year the rate of return was calculated after 4,7 years, while using the punch from the current second deep drawing operation it was calculated after 3,4 years.

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.

Production of lamp cover
Tóthová, Romana ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
Project dissertate about manufacturing of lamp cover of steel 13 200 in serie 43 000. After comparing all the alternatives how to make the product , was choose a method of convention deep drawing. Product is manufactured in one operation. Design of apparatus using as standardized, so special parts. It is fitted in hydraulic pressing machine CTC 25. Functional parts are made from tool steel 19 191. Costs of production was calculated on 15,21 crowns a piece. From 26 173 manufactured pieces will the production gainful.

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

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.
