The manufacturing of motorcycle tab by blanking technology
Jandík, Radim ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This bachelor’s thesis deals with the issue of manufacturing of motorcycle tabs. The tab is made from rust-resistant sheet aluminium (42 4412). The manufacturing process begins on a manufacturing line; it is automated to a great extent and controlled via CNC. If run at full capacity, the line can produce as many as 450 tabs per minute. A total of 300 000 pieces of tabs are manufactured per year. This order is planned to span over five years, during which it shall generate profit amounting approximately to CZK 1.74 million. Economic comparison of laser cutting, water jet cutting, plasma cutting and blanking technologies has confirmed the suitability of the blanking technology for the production batch in question. The quantity of tabs in stock is minimal, as the production process is organised in line with the customer’s requirements.

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.

Forming of thin-walled tubes
Baránek, Tomáš ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
This work brings a synopsis of technologies used in the process of thin-walled tubes forming as well as their evaluation. There are various forming methods applied in order to achieve a required shape e.g. tube bending, radial tube tripping and tube forming. The bending is done by several means e.g. collaring, reeling and pressing. In the pipe bending operation the tube may get deformed. Thus there might occur the following bending defects e.g. wall thinning, excessive flattening, wrinkles in the bend, tube suspension. At the radial tube tripping may occur local tube tapering or tube diameter attenuation. Tube forming is dividend into inlet, outlet and flattening.
