The manufacturing of electromotor covering
Stejskal, Luboš ; Špaček, Jindřich (referee) ; Podaný, Kamil (advisor)
This project has been presented for the bachalor branch of study, B2307, it shows the proposal of technological and production process for deep drawn parts. They are produced from the steel (11305). Due to the production volume of 100.000 pieces per year, it was proposed to implement the production process. It basis of the literature study which describes the potential pitfalls of deep drawn technology. After control a technological calculations it was decide to choose the stamping machine CTC 250 (manufactured by ŽĎAS, a.s.).The deep drawn tool has been designed in order to use the maximum capabilities of this stamping machine, specially the upper ejector and the lower holding device.
The suggestion of shaped hollow cup technology
Fabík, Pavel ; Šlais, Miroslav (referee) ; Císařová, Michaela (advisor)
The project developed in the master's degree in M2-P, proposes a technology of hollow metal components DX53D+Z275N+NC with holes sheet metal forming. For batch production 225 000 units per year, on the basis of literary study problems of production of components there is designed a new way of producing components for progressive tools and it is compared with current production of simple tools. A progressive tool has 12 steps and combines them in cutting, drawing and extrusion. The tool is mounted in the hydraulic press KAISER KSTU2500 with a maximum force of 2500 kN. Simulations were performed for the campaign in the PAM-STAMP 2G 2011.
Drawing of a tin-coated metal sheet
Hudousek, Jiří ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
HUDOUSEK Jiří: Drawing of a tin-coated metal sheet. The project elaborated in frame of master studies is submitting design of the given part production - business card case from tin-coated metal sheet by deep drawing technology. From a variations of the design of the product has been chosen option, when the case is assembled from two identical drawn parts which form the bottom and the lid of the component, the connection of these two parts is arranged by a spacer in form of a plastic insert on which the metal parts are attached. Based on the literary survey and calculations drawing in die with blankholder was designed for metal parts production, according to the force needed and tool size a hydraulic press ZH 100 was selected. Part of the work is the process parameters determination, technical and economic evaluation and drawing documentation.
Manufacturing of car company logo
Prouza, Tomáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The logo component will be produced in a series of 8000 pcs. It will be made from sheet metal 0.5 mm thick stainless steel 17 040. After evaluation of possible modes of production, chosen technology is stamping non rigid tools Guerin. As a medium is used POLYTAN. Literary study is focused on the analysis of this technology. Semi-finished product have circular shape with a diameter of 104.9 mm. Semi-finished product will be produced by use cutting waterjet from steel sheet of size 0.5x1250x2500 mm. Utilization of the steel sheet is 76.58%. The forming components are powered by hydraulic press ŽĎAS corp. Cth400 and a nominal force of 4 MN. This machine is in a manufacturing company available. On the basis of design calculations is chosen comply a tool for Guerin method. When you set a margin 30%, the total profit from the production is 24 096 CZK.
New trends in processing of metal sheet with coating
Veverka, Štěpán ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
Presented document worked out as the part of bachelor study B2339-00 Mechanical Engineering deals with new trends in processing of coated metal sheets. With consideration of available literature are introduced issues of surface treatment, cutting, bending, drawing and spinning of altered sheets including also the descriptions of some machines which apply these technologies.
Production of gully
Švejda, Jakub ; Jopek, Miroslav (referee) ; Podaný, Kamil (advisor)
The project elaborated design of technology production of the gully – the rotational extract with flange from the deep drawing corrosion resistant sheet iron 1.4301. Pursuant to of the literary pursuit and calculation was designed drawing without thinning the wall in two operation and that in one instrument with two bottom holders enabling their combination into one stroke. The drawing instrument makes use of as standardised components as construction elements calculated using calculations and consist of three parts. The bottom and upper are magnetically clamped on the hydraulic drawing press Dieffenbacher PO 250, with nominal tensile force 2500 kN. Both drawing punches and drawing dies are produced from alloyed instrumental steel 19 436.9 heat-worked according to drawing documentation.
Forming Technology of Thin Sheets
Vymazal, Aleš ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The presentation of bachelor thesis deals with the thin metal sheet technology of forming for rotary and non rotary shapes. The focus is on knowledge transfer from the foreign literature. Selected formulas were compared for a given sample of steel 17240.
Manufacturing of biscuit pan
Pešava, Josef ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The solved part – the „cookie cutter“ is made of tin material TH 370 0,24 mm thick. It will be used for baking cookies at temperatures up to 250°C. Estimated annual series is 100 000 pieces. The most optimal method from the variant solution of the production of the part was chosen. In the first operation the circular rondel is cut from the sheet and there is the conventional campaign in the second operation. Based on calculations the nearest suitable press LEN 25 C is selected for the production. The price of 2,58 CZK per mold was calculated in, the technical-economic evalution. The pull tool is designed from technological and design calculations.
Forming Technology of Thin Sheets with Coating
Procházka, Lukáš ; Schwarzer, Emil (referee) ; Dvořák, Milan (advisor)
The bachelor's thesis deals with forming technology of thin sheets with coating. It is divided in three separate parts. Firstly, technologies used for forming thin sheets with coating like bending, drawing, spinning and shearing are discussed. Secondly, the thesis presents coatings, their types and means of measuring their thickness as well as examination technologies. The last part consists of a set of experiments testing aforementioned facts on testing samples.
Production of light holder
Němec, Miroslav ; Peterková, Eva (referee) ; Žák, Ladislav (advisor)
The project elaborated design of production technology of light holder for agricultural tractors. Light holder is made of deep-drawn steel DC 01. For a production series of 30000 pieces, the production using a progressive die. The part will be manufactured in five steps. For production of the component was chosen hydraulic forming press CTH 250 of nominal force 2500kN from the company ŽĎAS. Total production costs of the component were calculated at 79 CZK.
