Optimalisation of evaluation methods for phosphating bathes
Brzuchańská, Anna ; Trčka, Josef (referee) ; Zmrzlý, Martin (advisor)
This work deals with phosphating technology of steel. In theoretical part are summarized facts about conventional phosphating process, including steel surfaces pretreatment. In the next chapter the latest contemporary technology of phosphating is discussed, i.e. electrolytic phosphating. This chapter contains principles and characteristics of this technique. Than follow comparisons of electrolytic phosphating and conventional process, concerning economical and ecological aspects. In experimental part is firstly stated nowaday situation of process analyses of phosphating bath for electrolytic phosphating. Intention of experimental part is finding of analytical technique which can be used in operating conditions of phosphating production line. Next chapter render an account of all analytical techniques – measuring of density, refractive index, conductance, reduction potential, pH, turbidity and determination of sulphate, iron and phosphate by indicator papers. Discussion of all results leads to conclusions on tested techniques in connection with practical use in operating conditions of phosphating production line and recommendations for use of individual analytical techniques.

The Production Technology the fan cover
Hudousek, Jiří ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
HUDOUSEK Jiří: The Production Technology the fan cover. The project elaborated in frame of bachelor studies is submitting design of the fan cover production with sheet metal forming technology. Based on the literary pursuit a production process of the workpiece was designed when the blank is formed with deep drawing technology without thickness reduction (pure drawing) and subsequently completed by trimming to size, dimpling of the shell bottom, assembly holes punching and surface treated. Based on the calculation drawing in die with blankholder was designed for drawing operation and according to the force needed and tool size a hydraulic press ZH 160 (manufacturer PRESSHYDRAULIKA, s.r.o.) was selected. Material chosen for the production of workpiece is deep drawing steel sheet DC04 (ČSN EN 10130), production batch is 100 000 pcs. per year.

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.

Technology of production cover by forming
Řezáč, Patrik ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
The aim of this Bachelor's thesis is to develop a technological process of a production concerning the tank lid forming, namely the cold forming - technologies for deep drawing. As a material for the production of steel is chosen P 355 NB intended for the production of pressure tanks. Parts of this work are also technical drawings developing of LPG tank, of the tank lid, of paper-weight assembly, and the drawing of dies.Technological calculations needed for the production are the integral part as well. And also a choice of machines for the production and economic evaluation of the production process.

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.
