Production technology of plastic parts for automotive industry
Šobáň, Jakub ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The diploma thesis presents a production technology design of an automotive industry component – a resonator holder. The initial production run of the part is 500 000 pcs. Injection production has been selected based on variant analysis of available technologies. Technological calculations have been performed. The selected material PP 56M10 will be used for operation in granules. A quadruple shaped cavity injection mold with a tunnel gate has been designed. Based on estimated technological properties an Arburg Allrounder 470 A machine has been selected. The break-even point (BEP) shows economic return at the production of 185 595 pcs.

Production of holder by solid forming
Nejedlý, Petr ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The project elaborated in frame of engineering studies branch 2307. The project is submitting design of technology production of holder by solid forming of steel 12 020.0. Pursuant to of the literary pursuit a problem of die forging and calculation was designed forging on a vertical cranked press LMZ 1600 and with nominal forging force 16MN (producer ŠMERAL Brno). The lower ejector is using for extrusion component.Heating billet is accomplished by using induction furnance type SOP 400kW.For trimming is used trimmning press LKOA 200 with force 2 MN. For holding of dies is used holder QLZK 1600/UC, dies are made of instrumental steel 19 552.9. A part of this project is economic estimation of production and produce of manufacturing drawings.

Production of holder
Andris, Tomáš ; Podaný, Kamil (referee) ; Lidmila, Zdeněk (advisor)
The project elaborated the design of technology production of the holder used for fixing pneumatical cylinder at the testing rack. The holder is manufactured from 2 mm thick sheet metal made of structural steel 1.0038 in a production series of 6,000 units/year. After considering the individual production options, shearing in transfer die and simple bending die were selected. Based on the literature study of shearing and bending technology, an optimal production process of the holder was proposed. After technological, structural and verification calculations, the tools were designed, and the technical documentation was prepared. For the production of the holder was selected eccentric press LEXN 100 C made by Šmeral Brno a.s. This press meets the requirements of the forming force, forming work and the dimensions of the tool. According to the calculated economy of production, the production costs of one holder were determined with a 30 % profit to 97 Kč. The turning point when production becomes profitable was calculated to 4 454 units.

Production of holder by solid forming
Šimon, Miroslav ; Novotný, Karel (referee) ; Kopřiva, Miloslav (advisor)
The aim of this dissertation is to design an optimal technological processing of a given component by solid forming. This work includes a bibliographic study, which is the source of information for the solutions. Another important topic is the global technological processing of the given component: to begin with gear blank design until the final product. The best option seems to be the die forging on forging press in three steps. From an economical point of view, the die forging realized according to the designed technological processing appears to be the best solution.

The manufacture of cylindrical case by forming
Kratochvíl, Tomáš ; Císařová, Michaela (referee) ; Dvořák, Milan (advisor)
Bachelor theses done within bachelor study of specialization in an Engineering technology submits a proposal of production technology of a headless bushing by shaping. A proposed production technology of graded bushing involves an operation of cut-out of semifinished material, draw of an extract with the flange and a curtailment of the flange. The draw is made on the basis of calculation in three operations with the help of holder. According to graphical documentation the extract gets the final shape in the last operation of draw. The purpose of bachelor theses is a design of technological processing and elaboration of drawing documentation of an implement for making the headless bushing.

Forging production of Holder of steering pivot
Moudrý, Michal ; Kopřiva, Miloslav (referee) ; Novotný, Karel (advisor)
MOUDRÝ Michal: Forging production of holder of steering pivot The project was elaborated in frame of engineering studies branch 2307. The aim of the project was to propose design of technology production of steering pivot holder using solid forming of steel 12 040.0. Based on literary study on die forging and made calculations forging on a vertical crank press LMZ 1000 with nominal forging force of 10MN was designed (producer ŠMERAL Brno). Lower and upper ejectors are used for ejection of components. Induction furnace type SOP 250/6-A30 P/L/T will be used for heating of the raw material. Trimming will be performed using trimming press LDO 315 A/S with press force of 3,15 MN. Dies are made of instrumental steel 19 663.9, for their clamping die clamping device QLZK 1000/UC will be used. A part of this project is economic evaluation of the production and development of production drawings. Keywords: solid forming, die forging, steel forging, holder

Manufacturing of a VESA holder
Večeřa, Jaromír ; Podaný, Kamil (referee) ; Peterková, Eva (advisor)
This diploma thesis presents a proposal for manufacturing of a monitor holder supporting the VESA mounting system. The part is made of DC01 steel with a thickness of 2 mm, while the size of the production series was set at 150,000 pcs/year. After considering possible production variants, the use of a progressive combined tool combining cutting and bending was chosen as a suitable method. After technology control and selecting a suitable production process, calculations of forming forces and work were performed. The total force was set at 699,7 kN and the total forming work reaches 1,2 kJ. The S160 press from the company Šmeral Brno a.s. was chosen as a suitable machine for production. The semi-finished product in the form of a metal sheet coils will be fed into press by feeding device.

Design of adaptive wiper of liquids
Novotný, Antonín ; Nečas, David (referee) ; Košťál, David (advisor)
This thesis deals with the structural design of the adaptive fluid wiper, which is the complement of laboratory equipment. Laboratory equipment is used to study the thickness of the lubricating layer and the frictional force at contact. The purpose of the adaptive wiper is to remove the maximum amount of liquid from a moving planar disc or to make a uniform film in a rolling path around the periphery of the disc. Among the most controllable features, there are the wiper geometry, the evenly pressing and the follow the disc throwing. The thesis includes the design report, drawings and 3D model.
