Production of wash basin strainer
Pecha, Oldřich ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
Bachelor's thesis focuses on wash basin strainer fabrication technology. This rotary component will be made from ČSN 1.4301 (X5CrNi 18-10) material. Stated annual production is twenty five thousands completed products. Chosen technology for fabrication is drawing with no wall thinning with the use of hydraulic press LEN 25C. Tool for deep drawing will be used for completion. This tool's drawing documentation is enclosed in this thesis. Single-operation tool for deep drawing was designed. This tool contains blank holder, punch, die and gas spring. In the economical section was calculated that total cost of one product is 33 czech crowns. For the production to generate income at least 13 628 products would have to be made.

Production of grill lid
Míka, Tomáš ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The thesis is focused on the design of the production of kettle grill lid from steel 11 305 (1.0338) with a constant wall thickness of 1 mm and a series of 10 000 pcs/year. For the selected method of manufacture by conventional drawing, technological calculations were performed. Depending on the diameter of the blank, maximum force and other parameters, the tool and the machine were designed. The tool is a single-operation drawing tool with a blank holder and a rib around the perimeter. These functional parts, together with the drawing punch and drawing die, are made of surface-treated cementitious steel 14 220 (1.7131). The drawing tool is clamped into a CBA 250 hydraulic press with a nominal force of 2 500 kN, where the blank holder is controlled by an additional device at the bottom of the press.

The suggestion of technology of protection cover
Vágner, Vladislav ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
he project executed in frame of Bachelor study presents a suggestion of manufacturing technology of cover made of deep drawing sheet iron DC 04. The theses includes comparing of possible manufacturing technologies and elaboration of manufacturing procedure by deep drawing. Based on calculation was discovered that there are four drawing and one calibrating operations needed. The CTC 250 press was chosen and for it was the tool designed for a first draw. In the theses was included economical-technical evaluation which shows that set of 50 000 pieces a year is profitable.

Manufacturing of belt drive cover
Rösner, Michal ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
Master’s thesis submit a concept for belt drive cover manufactured by ČSN 411320.21, a 1.5 mm thick material for series 10 000 pieces. On the basis of manufacturing method are presented problems around drawing, the parameters, used machine with tool design. For deep drawing operations were carried out control, computing technology, a hydraulic pres CTH 250 selection, designed set of drawing tools, simulation by AutoForm software, a technical economic evaluation, break-even point and supported by drawing documentation.

Technology of emitter production
Šrotíř, Petr ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
The goal of this bachelor thesis is to compare the technologies of production of given workpiece using the technology of spinning and deep drawing. The object of this project is an emitter and is supposed to be made of sheet metal. The workpiece will be deep drawn in the experimental drawing tool. An economic review by production of 1000 pieces will be worked out at the end of the bachelor thesis.

Manufacturing of body latch
Janáček, Adam ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
Thesis evaluaes production of the body latch, which is used for window, window shutter and door locking. It is made from 11 375 steel sheet which is 1 mm thick. Annual production is 50000 pcs. Progresive cutting and drawing in one combined tool and finishing product in single opperation drawing tool was choosen as most effective. Single operation drawing will be operated manually. Tools was designed by series of technological callculations to which was projected presses Šmeral LDC 160 with additional devices. Acording to economic valuation, cost of production of one piece is 16,50 Kč and production becames profitable after production of 27185 pieces.

Production of shower tray
Černý, Vít ; Žák, Ladislav (referee) ; Císařová, Michaela (advisor)
The thesis deals with design of technology production of the shower tray made of austenitic steel 17 240. Based on the research of deep drawing and calculations, it was proposed to draw in the tool with upper blankholder and the lower ejector. The drawing tools uses standard components that ensure its functionality and clamping in the CYA 500 hydraulic press with nominal tensile force of 5000 kN. Drawing punch and die are made of 19 437.3 grade steel, heat treated according to the attached drawing documentation.

Production of filter cup
Míka, Tomáš ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
This work is concerned with the design of producing a filter cup made of material 17 240 (1.4301), 0,5 mm thick and the series 100 000 pcs/year, used in the lever of the espresso machine. The method of conventional deep drawing without wall thinning was chosen as the most suitable technology for the production of body cup. Utilizing calculations, an initial semi-product of circular shape with a diameter of 92 mm was determined. By means of technological and constructional calculations a single operation tool was designed, with the upper blank holder and knockout, which is intended for use with a double-acting press. Its functional parts are made of material 19 436. According to the calculated total force a double acting hydraulic press CTH 250 was chosen.

Production of ceiling light
Kvasnička, Jan ; Řiháček, Jan (referee) ; Císařová, Michaela (advisor)
The manufactured component is the inner part of the ceiling lamp. It is made of 17 240 steel in a series of 100 000 pieces/year. A combination of tool cutting and deep drawing without thinning the wall was chosen from the possible production technologies. The diameter of the blank from which the resulting shape is pulled out was calculated to be 400 mm. It will be cut from an unwound coil of sheet metal, the inner diameter of which is 400 mm and the outer 1000 mm. A drawing tool was designed for forming and it's functional parts were made of 19 436 steel. The tool is placed in hydraulic three-acting press PO 160/100 from company Dieffenbacher. The press is part of a line which includes an unwinding device, a straightening device and a cutting tool.
