Optimization of the Wire Drawing Process
Kabilka, David ; Světlík, Radim (referee) ; Řiháček, Jan (advisor)
The aim of work is to present and analyse assessment of the current state and at the same time the proposal of adjustments to the technology or parameters, the introduction of the wire into the drawing machine. The problem arises when the introduction of wire with a diameter of 14 mm from the material CK 67 to the drawbenches Schumag. If we introduce the wire into the drawing machines with two primary beams leads to a buckling of the wire and pack between the drawing die and the boot device. For the introduction of wire are used hydraulic boot collets, which are controlled semi-automatically. In connection with professional studies and on the basis of the calculation, simulation and practical experiment have been identified the conditions allowing the current method of deployment of wire to use.

Productive single parts from shet metal by the help of technology Hydro- Mac
Štancl, Jiří ; Dvořák, Milan (referee) ; Žák, Ladislav (advisor)
The project in this bachelor thesis solves a proposal of design technology production of extract from deep sheet iron 17240, thickness of 2 mm. Pursuant to of the literary pursuit a problem of the deep drawing, calculation and production of 40 000 pieces a year, was designed hydromecanical deep drawing. Drawing tool is fixed in hydromechanical press EMU 4000 by AP & T company. This press reaches nominal force of 4000 kN. Drawing punch is produced from instrumental steel 19 436, heat-worked according to drawing documentation.

Wire Drawing Technology
Štys, Michal ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The paper presents current research on the technology of wire drawing with focusing on the analysis of process factors, their calculation and influence on the process itself. The research describes drawing methods and technological process of wire drawing. The work also deals with geometry and die materials and their effects on process quality and tool wear. Subsequently this thesis analyses currently used machines and their advantages and disadvantages. As well as their suitability for use depending on the materials of the drawn wires and economic profitability. At the end of the thesis, unconventional methods of wire drawing and their future development estimation are presented.

Coating of tools by the PVD HiPIMS technology
Havlíková, Tereza ; Ohnišťová, Petra (referee) ; Píška, Miroslav (advisor)
This bachelor’s thesis is aimed on the study of PVD coatings of tools with a focus on HiPIMS (High Power Impulse Magnetron Sputtering) technology. As part of the research, the PVD coating methods are presented, then the basic physical processes and characteristics of magnetron sputtering are described and finally the HiPIMS technology is analysed. The aim of the experimental part of this study is to evaluate (Al,Ti)N coating deposited by HiPIMS technology on a wire drawing die. For coated and uncoated die, the wear of the die, surface quality and thermal impact on the wire are observed and compared.

Production single parts from sheet metal with usage technology deep drawing
Jurča, Jan ; Dvořák, Milan (referee) ; Žák, Ladislav (advisor)
JURČA Jan: The manufacturing of sheet metal part by deep draw technology. Thesis of Master´s Studies, the 5th Year of Study, the School-year 2008/2009, The Institute of Manufacturing Technology, Department of Machining, FSI VUT Brno.The thesis deals with the project of manufacturing the part of the car body – the fifth door by deep draw technology. The material is zinc-coated sheet metal HX220YD EN 10292. Mechanical properties and suitability of the material are evaluated by mechanical tests. The structure of the material is evaluated by metalography scratch pattern. The analysis of draw process and manufacturability of the part is made by calculations and AutoForm software. The production line, necessary machinery and construction solution of draw tool for the manufacturing the part are determined. Last section deals with economical evaluation of the production.

Manufacturing of oil filter
Prokop, Karel ; Humlíček, Jaroslav (referee) ; Podaný, Kamil (advisor)
This thesis deals with the proposal of an oil filter body manufacture. The oil filter body is a rotational part made of DC02 deep drawing steel. With respect to the material, geometry and the size of the production, a deep drawing technology which does not consider wall thinning, was chosen. It was decided about necessity of five drawing operations. Suitable presses for a notching line and the very drawing were selected. Next part of the thesis is given to the design of the rolling tool construction. A drawing die for the first operation is described in details, including the controls and drawings. The economic part compares variants with the requirements of monthly production of 50 000, 180 000 and 350 000 pieces respectively. Due to the economic study, the production of 180 000 pieces per month was chosen.

The Production of the oil pan
Šupa, Jan ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The dissertation deals with a suggestion of the production of an oil pan into the car with a deep drawing. The part will be produced out of a deep drawed steel plate – class 11 305 (DC04). On the basis of a calculation and the study of the corresponding literature about the deep drawing a reverse drawing in a convention tools with a blank holder has been suggested. The part of the machine will be also an upper ejector for the fall of a sticking of a drawn part in the die. As a semi-product a blank has been chosen, which is burned out from the piece of plate with the dimension of 2500 x 12500 mm and thickness 1 mm with the help of the laser. The production quantity is 30 000 per one year. As a forming machine a universal hydraulic presser CTH 250 from the Czech company Žďas a.s. with the nominal power 2500 kN has been chosen.

Production of wash basin drain grid
Běhounek, Martin ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
This thesis deals with a draft on manufacturing a sink grill. It is a rotary component that is made of corrosion-resistant steel 17 240. Considering the material, the shape of the component and the size of the production lot of 100 000 pieces a year, the suggestion for manufacturing this component is a technique of a deep drawing with no wall thinning. It has been decided that the trimming will be done with a progressive blanking die and the deep drawing will be done with the use of pressing machine LKDA 315. One part of this thesis is a draft of a design of a tool for deep drawing enclosed in a drawing documentation. In the economic segment, there is a total of expenses for one product which is 9 CZK. Production becomes profitable after manufacturing 67 308 components.

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
