Engineering design of the hydraulic press for bearings for bikes
Vichr, Tomáš ; Brandejs, Jan (referee) ; Klapka, Milan (advisor)
This bachelor thesis concerns design of a bearing replacement device in the motorcycles wheels. The aim was to develop an affordable and reliable home appliance. In general research are defined the imperfections of commonly available devices on the market. Based on that are designed three conceptual proposals as a solution of these problems. The most suitable one is chosen and the critical crucial points are verified as well as the production price.

Workshop straightening hydraulic press
Ožvoldík, Daniel ; Tůma, Jiří (referee) ; Omes, Jiří (advisor)
This work deals with the design of a hydraulic workshop straightening press. This press is used primarily for basic operations needed in manufacture, such as straightening the steel plates or shafts. Furthermore, it is be used for bearing assembly or bending metal sheets. The essential parts of this work are the design of the electro-hydraulic circuit, the design of moving the press frame and the analysis of the mechanics of the material.

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.

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.

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.

Manufacturing of the part "shaker" by cold sheet metal forming
Pekař, Pavel ; Císařová, Michaela (referee) ; Jopek, Miroslav (advisor)
The project elaborated design of technology production of the extract from the stainless deep drawing sheet 0,3 mm steel 17 240. Pursuant to of the literary pursuit a problem of the sheering and deep drawing was designed sheering and drawing with blank holder in combined tool. The tool is solved like customary rack with guiding rods clamped on the hydraulic press for forming of sheet PO 100 with nominal forming force 1 000 kN. Shearing die, drawing die and drawing punch are produced from tool steel 19 436.9 heat-worked according to drawing documentation.

Manufacturing of Trailer Connecting Joint
Vahala, Jiří ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
The project elaborated design of technology production of the trailer connecting joint from the deep drawing sheet iron 11 320. Pursuant to of the literary pursuit a problem of the deep drawing and calculation was designed progressive tool concatenate four operations. The lower ejectors are using for ejecting components. The drawing instrument especially made of non-standardised components and it is designed for use on a hydraulic press CTH 250, with nominal tensile force 250 kN. Drawing punch and drawing die are produced from alloyed instrumental steel 19 436 heat-worked according to drawing documentation. The technical and economical evaluation was focused on the forming cost, which is 2 922 893 CZK in total.
