Manufacturing of Shaped Holes into Stamped Metal Sheet
Bartusek, Břetislav ; Hušek, Martin (referee) ; Dvořák, Milan (advisor)
The aim of bachelor thesis is a proposal of a new technology for manu-facturing of shaped holes into stamped metal sheets. The sheets are made of stainless steel DIN 1.4301 of thickness 0.8 mm. Square holes will be punched into a half-finished metal sheet with pre-pressed lengthwise stamps where elastic-plastic deformations occur. On the basis of study of the sheet metal forming technology, technological calculations and the machine adaptation, a new technology is proposed. The new technology is unassuming both with respect to machinery and tool equipment in a mechanical engineering factory. Also it enables solutions of dimensionally variable die stampings with stamps in higher quality for minimum costs. As the forming machine a punching press, model LDR 25-A, was chosen.

Forming technologies of non-ferrous materials
Zuhla, Michal ; Dvořák, Milan (referee) ; Císařová, Michaela (advisor)
This work is focused on the surface forming, in particular, non-ferrous metals. There are described methods of cutting, drawing and bending. For each of these methods are listed and summarized the issues. There are also given individual production technologies cutting, drawing and bending, along with examples of products and their use. The work is complemented with an overview of the most important non-ferrous metals. For these metals are described their properties, suitability for molding and their alloys.

Proposal for the production of variants of flat sheet metal parts with holes
Kohoutová, Zuzana ; Podaný, Kamil (referee) ; Špaček, Jindřich (advisor)
The final work elaborated in the scope of bachelor studies of the branch B2307-00 submitted proposal of variants for production for flat sheet steel parts with holes from the material 11 373. Work is set for cold shaping of metal by means of cutting and production by means of plasma CNC machine. Production on sequence shearing tool is based on series 150 000 pieces per year. Shearing machine S250 (manufacturer Šmeral Brno a.s.) with shearing force 2500 kN is selected for realization. Work is also focused on the production of the same components (valve) using a CNC plasma equipment and the subsequent economic evaluation of both variants of the production. In enclosure there is drawing documentation for cutting tool.

Proposal for the production of variants of flat sheet metal parts with holes
Fabík, Pavel ; Hušek, Martin (referee) ; Špaček, Jindřich (advisor)
FABÍK Pavel: Proposal for the production of variants of flat sheet metal parts with holes The project elaborated in frame of bachelor’s study branch B2307-00 submits a design of technology components from sheet metal with holes - parts of steel 11 320.1 (specified by INGE Opava). On the basis of literary study problems of production of the components were designed and compared two methods of production. Cutting on the combined cutter attached to the double-stand hydraulic press type Tleff (designed by KIT Invest Ltd. for the Trading) witch 4000 kN pressing power. The cut parts of cutting tool are made of material 19 312 (as designed by Brano). Laser cutting is done on a machine AMADO FO-3015 (in the company Dender).

The holder manufacturing
Isakidis, Petr ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The aim of the thesis is to propose a suitable technology for a production of a licence plate holder and motorcycle trafficators, which are from the thin metal plate. Production series is 600 000 items. The chosen material is 11 321.1 in form of the roll of steel. The thesis comprises of the theory of the topic of shaping, the proposal of an engineering solution including technology concept of calculations and choosing of a suitable option. The structural design of a procedural cutting machine is created by a modeling program CATIA V5, which was also a suitable instrument for technological calculations.

Analysis of Circular Bars Shearing Process
Dohnalová, Eva ; Hůlka, Jiří (referee) ; Foret, Rudolf (advisor)
In these days customers require a high quality as well as precision of products together with a cost that is as low possible. The cost of products can be reduced in a way of batch production. Implementation of the batch production requires a detailed plan of a technological process to avoid making depreciated products or series of products. A software package can be used to simulate the technological process of shearing to avoid difficulties of particular technological process. This bachelor paper contains analysis of technological process of shearing of circular section rods. The results of the analysis are going to be included in FEM simulations. The effect of the technological process of shearing on material was determined by optical and scanning electron microscopy method. The microhardness measurement was used to analyse the deformation hardening of the examinated material.

Technology project and layout for holder
Mottl, Jan ; Žák, Ladislav (referee) ; Rumíšek, Pavel (advisor)
Technology project and layout for holder. Bachelors thesis of the bachelor’s studies the 3rd year. School year 2008/2009, education group 3P1. FSI VUT in Brno. Institute of technology, department of forming. April 2009, pages 47, pictures 28, tables 2, supplements 9. Bachelors thesis which was elaborated in the frame of the bachelor’s studies branch 2307 submitting the technology project and layout of the holder. Component are produced from material 11 321 using of undermentioned literature pursuit a problem of the select material, sheet metal cutting and bending which was designed by cutting with processual tool and bending tool. At designed cutter and bending was used of standardised components. Project organization of production is designed so, to keep up produce of requisite series in a year.
