Technology of radial bearing steel cages production
Jabůrek, Petr ; Špaček, Jindřich (referee) ; Rumíšek, Pavel (advisor)
The project conceived within engineer’s studies of branch 2303T002 is subbmitting a proposal for radial bearing cage produce technology. It is also subbmitting a design solution to functional parts for blanking the “windows” and coining the “locks”. The cage will be made from sheet steel 11 300.29. This cage should replace the current one machined from the brass Ms 58 Al. According to the literary research and development experiences of the company ZKL Brno, a.s., two pairs of tools were designed. First one for blanking the “windows” and second one for coining the “locks”. Blanking punch, blanking die and coining punch will be made from the steel 19436, coining die will be made from the steel 19312. Heat-treating process will be accomplished according to the enclosed drawings. Both pairs of tools will be mounted in the press LENR 63 AU (manufactured by the company ŠMERAL Trnava), with nominal force 630 kN.

Uses of a cutting die in the manufacturing process
Důrek, Milan ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The bachelor’s thesis elaborated as part of a bachelor's degree of the branch mechanical engineering submitted a proposal of use cutting technology in the manufacturing process. The specified component is a tine and it is made of abrasion resistant and high-strength steel. The tine is produced in a series of 200,000 units / year. The first part of the thesis is pointed to technology of material cutting. For this technology a literature summary was made including a description of the requirements for the calculation of shearing machines and tools. In the second part, cutting tool was chosen based on technological calculations. For this instrument has been chosen crank press LKJA 1000 with a nominal force of 10 000 kN. The study evaluate the economic comparison of laser and cutting tool.

Cutting components with higher accuracy to size
Steiner, Jaromír ; Varjan, Matúš (referee) ; Žák, Ladislav (advisor)
The main topic of this thesis is the fineblanking technology with a vee-ring which was chosen as the most suitable solution. The aim is a design and an assessment of technologicity of the selected component, a draft of the structural design of the tool and an economic evalua-tion of the project. The chain wheel has been designed from structural steel 11500; parameters have been evaluated as appropriate. The instrument has been designed as two-station progressive tool for single-row layout of the fineblanked parts with a moving punch; the vee-ring is positioned both to the blanking plate and to the vee-ring plate. The press was chosen on the basis of the calculated shearing force by Feintool Company. At the selected batch 500,000 units, 5.1 CZK per fineblanket part has been calculated.

Production of sealing strips for aerating system
Brdečková, Zuzana ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The aim of this work is the production of sealing strips for aerating system. The strip is made by technology of production - cutting and bending of stainless steel 17 240 with a thickness of 1 mm. Lot size is 22,000 units per year. Based on the information on the state seal was designed a new, more efficient and more productive shape for the production. Then, it was done the literary study. On the basis of calculations was chosen the hydraulic press CUPS 25 D for the production. The sealing strip will be manufactured on the newly designed cutting and bending tools. The work is carried out with a techno-economic evaluation that compares the current production technology with the newly proposed technology. The work contains drawings of sealing strip, shear and bending tools.

Pulley cheek manufacturing
Habr, Stanislav ; Císařová, Michaela (referee) ; Peterková, Eva (advisor)
This bachelor thesis focuses on the technology of follow cutting. The purpose is to project a progressive press tool for the given component of a pulley cheek made of a stainless steel sheet with the thickness of 1 mm. The optimal variety of component production was set on the basis of the theoretical study in the first part of the project. The progressive press tool uses standardized components and it is realized by using the usual post which is fixed to the compressing machine LEN 63 C (producer TOMA Industries Ltd.). At the end of the thesis, there is an economic assessment of production of the annual batch of 200 000 pcs.

Proposal for the production of variants of flat sheet metal parts with holes
Hamáček, Petr ; Vonka, Vladimír (referee) ; Špaček, Jindřich (advisor)
HAMÁČEK Petr: Proposal for the production of variants of flat sheet metal parts with holes. The final work of bachalors studies, 3th grade, academic year 2008/2009. FME VUT in Brno, Institute of manufacturing technology, department of metal forming and plastics. Bachelor work elaborated in the scope of bachalor studies of the branch B2307 submitted variants of production for flat sheet metal parts with holes. Theoretical part of the thesis is pointed to theory of cutting and description of personál cutting process. Shearing machine LEPP with shearing force 1000 kN is selected. Blanking puch and blanking are made from 19 class alloyed instrumental steels, heat treated according to graphical documentation. Cuttingin machine is using standardized components and it is solved by particular frame into eccentric machine. In the work there are implied necessary calcullations for both variants including economical evaluation.

The manufacturing of feed sheet metal component
Pašalov, Tomáš ; Matušková, Jarmila (referee) ; Peterková, Eva (advisor)
The project made within the bachelor‘s program B2307 represents a proposal of the production technology of a cutting – a device made of steel plate 12020. On the basis of secondary literature dealing with the problematic topic of cutting technology a production of components in sequential device was designed. The sequential device is composed of normalized components and is resolved by using a universal easel. The cutting box is fixed to the compressing machine LEN 40 C (producer TOMA Industries, s.r.o.) with the nominal drawing force of 400 kN. The upper cutting edge and cutting form are made of tool steel class 19, heat-treated according to the drawing documentation.
