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.

Influence of input material on technology and production of deep drawn product
Černá, Monika ; Peterková, Eva (referee) ; Šulák, Ivo (advisor)
This bachelor thesis was elaborated in cooperation with company ITW Pronovia, s.r.o within the scope of the bachelor degree and presents an assessment of the effect of material properties and manufacturing technology of a deep-drawn product. In this work the mechanical and technological tests were carried out on the supplied material HT179. This material is further processed into a cartridge for an airbag deployment. During production many defects occurred, especially after cutting out the holes of deep-drawn product. The company established these defects as material property. Therefore it is necessary to evaluate the characteristics of different material sets.

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 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 the electric motor cover
Havlíček, Lukáš ; Staněk, Vojtěch (referee) ; Podaný, Kamil (advisor)
The present thesis solves a design of electric motor cover; specifically it deals with manufacture of cover body. A drawing is of simple flange-free cylindrical shape made of deep-drawn 11 305 steel sheet. With respect to the given shape of the component, material and annual series of 25,000 pieces, the most suitable technology selected was the method of deep drawing without thinning the wall by means of conventional tools. The process of deep drawing will be performed using a single-acting deep drawing tool supplemented with technical documentation. This tool is designated for the hydraulic press ZH 40 with a total drawing force of 400 kN. In the technical-economic part, the price of one product (respecting the indirect costs) was calculated for 42 CZK.

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

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.

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.
