Production of supporting plate
Filip, Jiří ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The thesis presents a proposal of technology for production of supporting plate, which is a top part of a service trolley, serving for manipulation with switch of high voltage. The supporting plate is manufactured of low carbon, deep drawing steel DX51D+ZM thickness 2 mm and quality according to EN 10346. Annual serie was set for 200 pieces. In evaluation of production possibilities were chosen technologies of punching and bending. There was designed unfolded shape of the sheet metal with dimensions 1068 x 900 mm and created cutting plan. As was found, from one metal board is possible to cut out 2 pieces of the supporting plate, while 70% of material use. In the next step, punching tools were chosen and manufacturing process was made. The highest achieved cutting force was 122,8 kN. The chosen machine is hydraulic CNC press TruPunch 5000. For bending there was created a bending plan, according to which bends will be made in thirteen steps. Used bending tools are punch OW209/S and two types of matrix EV005 + FWZ and EV006 + FWZ. Maximal achieved bending force is, according to the calculation, 259,8 kN. Bending operations will be made on CNC press TruBend 5130. In a technical and economical evaluation was determined cost for the material, which is 57 337,5 Kč.

Manufacturing of wheel holder for washing machine
Kopřiva, Tomáš ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The project is design technology components by cutting and bending. It is a component, which is used for attaching wheel of waching machine.It is manufactured from sheet steel. Analysis of suitable technologies for the production of manufacturing were selected in the combined processing tools. The tool uses standard components for cutting and bending, which is done on an eccentric press LEN 40 (manufacturer ŠMERAL Brno), with a nominal tensile force 400 kN. The prize of holder is about 8 Kč.

Technology of production reinforcer for car
Spurný, Petr ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
The project, which have been created within the framework study of engineering branch N2301-2, submit technology project of presswork – car reinforcement from material H 220 P and concept of multi-tool set design for pressing operations 1, 2 and 3. Technology process was designed in six operations, based on literary study of blanking and drawing technology. Multi-tool set is design in according with transfer press Müller Weingarten 1250T-1, which was chosen on the basis of advantageousness calculation. Project includes technical and economical evaluation of elaborated technology whit two other variants of production.

Metal forming production of bush by cold extrusion.
Šimeček, Tomáš ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
ŠIMEČEK Tomáš: Metal forming production of bush by cold extrusion. The project elaborated in frame of bachelor study degree brings a proposal of step by step metal forming production of bush by cold extrusion. Workpiece is made of normalized circle-shaped bar using 12 050 steel. The step by step production is based on literary pursuit of volumetric forming and calculation and is designed into five steps containing cutting, pressing and extrusion. These operations will be done on multistage pressing automatic machine TPZK 25 manufactured by ŠMERAL Brno, plc. with nominal pressing force of 5MN. Semi-finished product is placed into tooling´s workspace with manipulator. Final part extraction is solved with ejector integrated in automatic machine. Tools are made of tool steel, extrusion punch is designed of 19 550.4 steel, extrusion die is designed of 19 436.4 steel and extrusion die´s band is designed of 19 733.4 steel. Tools are designed to be improved by hardening and drawing.

Production single parts "Ring" from sheet metal
Stejskal, Luboš ; Rumíšek, Pavel (referee) ; Žák, Ladislav (advisor)
This thesis elaborated within a master degree in 23-03-T002 line, introduces a suggestion of production technology of part „Ring“ by sheet metal forming out of deep-drawing steel W.Nr. 1.0338. Supposed production amount is 250 000 pieces per year. Based on a literary study of problematic of sheet forming for this required part regarding production series, technologies of this of deep drawing and cutting were chosen. According to performed technological calculations, a production process of seven operations was designed. A sequence automatic machine Paust 40 (VVB WMW), was cousin for this suggested process. This machine is particularly appointed for big series and wholesale production of impressions of sheet metal. It is equipped with mechanization and therefore creates a fully automatic line. A tool was designed for this chosen type of machine. Project includes economical evaluations of elaborated of production technology.
