Fineblanking component and its manufacturing
Lata, Miroslav ; Peterková, Eva (referee) ; Šlais, Miroslav (advisor)
The diploma thesis deals with a propose of a new manufacturing technology of component called „KULISA“ drawing number 4-DP-05-10/01. The beginning of this work is prepared as a literary study about blanking. There are explained some basic concepts necessary to introduce a blanking topic. Other interest of this work is an assessment of actual state of conventional blanking technology which is being currently used for component production. With regard to the deficiencies of the existing method is proposed new technology of fine blanking. In the proposal is evaluated technological site of component construction and blanking tools are proposed with stress analysis included. Last part of the work deals with the economic evaluation, where is being compared efficiency of existing and new technology.

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.

Technology groove manufacture on a shell clamping element
Brdečková, Zuzana ; Žák, Ladislav (referee) ; Lidmila, Zdeněk (advisor)
The aim of the thesis is the design of the production process and tools for production of two grooves in coats of concrete clamp. Shell anchors are made of longitudinally welded stainless steel tubes 17 240. The size of the production of all types of shell of concrete clamps is 18 000 PCs per year. The number and the dimensions of grooves in the coats of anchors were determined on the basis of a practical verification. To the present day the grooves are made by cutting on a band saw, which is little productive and on finishing operations demanding way. The grooves in the coats of anchors will be newly manufactured by technology of shearing, which was a literary study. On the basis of the calculations was selected for the production a hydraulic press of CUPS 25 D. The grooves will be produced on the newly designed shearing tool. Work is carried out by technical-economic evaluation, which compares the current technology of production with the newly proposed technology. Part of the thesis is drawing documentation of coats of concrete clamps of all dimensions and drawing documentation of shearing tool.

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.

Optimisation of punch tool for produce holes of bearing cage
Matail, Petr ; Jopek, Miroslav (referee) ; Peterková, Eva (advisor)
The thesis is focused on analysis of causes of blanking punch cracking, which is used for piercing holes of barrel bearing cages and designing of new construction solution by changing shape of blanking punch. Multiple variants of rounding shearing edge and chamfering shearing edge was designed. The current state and designed variants were analysed by simulation in Simufact Forming program. The variants were compared by shear force progress, equivalent stress, contact pressure in blanking punch and effective plastic strain in blank cage. According to mentioned criteria the best solutin with rounding shearing edge by 0,7 mm and chamfering face of blanking punch by 10° was chosen.
