Production of the Folding meter lock
Václavek, Petr ; Lidmila, Zdeněk (referee) ; Žák, Ladislav (advisor)
The thesis proposes a concept of manufacturing the folding meter lock. The part is made from DC01+LC steel of 0,3 mm thickness. The series size is 100 000 pcs/year. A forming in a progressive combination tool combining shearing, bending and stamping was chosen for the production, based on the analysis of possible solutions. The tool, designed on the basis of literary research of used technologies, produces the part in eleven steps exerting maximal force of 38,5 kN. The production will take place on an eccentric press LEN 40 C. The market price of 3,38 Kč for one piece was established by the technical and economic evaluation.
Influence of anchor stamping process on the function of pressure control valve
Koumar, František ; Jopek, Miroslav (referee) ; Peterková, Eva (advisor)
The project elaborated a possible simplification of the tool which is used for stamping of the anchor of pressure control valve (PCV). PCV is manufactured at Bosch Diesel s.r.o. Jihlava. The resulting change will reduce the cost of tool production. Current tool can be manufactured only in one company in order to achieve precise dimensions. Based on the comparison of internal stamping, it obtains the dispersion of depths for further tests. Optimal a force is obtained from these tests, followed by limit sample tests. The tests show that modified tool is not suitable for stamping on the force for anchors with limited hardness. It is necessary to use a more suitable variant. A more suitable variant is stamping on the track. With this method, there will be less effect of the hardness of the anchor. The test on stamping on the track will be performed in the second half of 2020 and, if successfully validated, will be introduced into the series.
Tools for the Deep Drawing Technology
Lukeštík, Tomáš ; Císařová, Michaela (referee) ; Řiháček, Jan (advisor)
The project includes overview of technology of deep drawing and analysis of individual methods with including their utilization. In the first place, the project is about manufacturing and construction of tools for the deep drawing technology. It also includes description, relations and utilization of individual parts. It also mentions problematics of defects and lubrication.
Production of cover plate
Rubáš, Petr ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
The thesis is focused on the proposal design of the technology of the production of the cover plate of the lock, which together with other parts forms part of the fifth door of the passenger car. The cover is made of 2 mm metal sheet and includes a number of bends, embosses, cuts and trimmed holes. Based on production requirements and a series size of 1,200,000 pieces over 3 years, the production using a progressive composite tool was chosen. The part will be made in eleven steps composing of cutting, stamping, bending and edging. Micro-alloyed structural steel S355MC was chosen as the most suitable material. The part will be produced on the press KSTU 5000-30-7G RKM from the company ANDRITZ Metals and the price of the product is 14,33 CZK.
Diagnostics of Historic Masonry Construction
Grygar, Zdeněk ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
Bachelor’s thesis describes historical overview of progress of masonry elements, including their technology production. Define used methods of diagnostics masonry structures and characterizes their implementations and evaluations. The essence of designing characteristic and designing strength of masonry in compresion is desribed in conclusion. As the result of this bachelor’s thesis is summary up diagnostic problematics and try out diagnostics methods on real object.
Manufacturing of clasp
Polách, Libor ; Řiháček, Jan (referee) ; Podaný, Kamil (advisor)
The project is focused on proposal of clasp technology production. The clasp is a part of central lock in parachute harness. The part is made of galvanized steel sheet metal, sheet metal thickness 3 mm. The part has a spatial shape with holes. Expected manufacture series is 25 000 per year. Bassed on literary studies and manufacture requirements on the clasp, the method of cutting combinated with stamping in combined tool was found the most optimal. The final shape of clasp will be done in three steps. The nobel steel 12 050, which performs required mechanical properties, was chosen as the main material for clasp manufacture. The manufacture will be made by eccentric press LEXN 100C. The expected price of the clasp is 9,7 CZK per piece with counting the procurement price of metallurgical semi-finished product and the tool.
Control of the pneumatic press
Lichosyt, Tomáš ; Pásek, Jan (referee) ; Štohl, Radek (advisor)
This thesis deals with the creation of the control program according to the standard 88. Document contains a brief description of the security features of the model of the pneumatic press. It also focuses on the description of the standard 88 and its subsequent implementation on the pneumatic model. Next part of this document describes the development environment FactoryTalk Batch, which will be used for batch control. The next is a description of the phases formed in RSLogix 5000, configures and recipe created in the FactoryTalk Batch software. The last point is the creation a product for pressing and stamping.
Analysis of the material and technological parameters on the insertion of a sealing ring and their optimization
Munduch, Ondřej ; Bothe, Martin (referee) ; Píška, Miroslav (advisor)
This project addresses the issue of pressing sealing shaft ring in the flange. Effect of flange material changes to static leakage between the flange and the sealing ring, the surviving process parameters. An optimal use of process fluids to eliminate leaks.
Production of parts for window fittings
Havliš, Lukáš ; Špaček, Jindřich (referee) ; Žák, Ladislav (advisor)
This project submits a proposal for manufacturing technology of casement and frame window hardware base, made of 11343.23 steel 2,5 mm in thickness and with 15000 pieces annual production volume. The components form an integral part of a window hardware arrest mechanism. From potential variants of manufacturing, the technology of stamping and bending, with the use of a combined tool, was chosen. A bibliographic search examining these technologies was made and the machine LE 250 with nominal forming force 2 500kN was selected. The project comprises structural and technological calculations, including the combined tool design. In the economical part of the project, the product prices were quoted and the break-even point was determined. The break-even point is broken as soon as 13 046 pieces are manufactured.
Proposal technology of production scheet-metal part of car body
Sviták, Martin ; Špaček, Jindřich (referee) ; Žák, Ladislav (advisor)
The Master’s Thesis is focused on stamping of sheet metal parts. The analyzed part is a structural part of an automobile body. The part is made of DC04 (cold rolled mild steel) material. The annual pruduction volume is 10.000 pieces. Theoretical background research is a knowledge base for design of tooling that can produce parts which meet quality requirements. There are three technological processes proposed in the Thesis. An economic analysis identifies the optimal technological process for the production volume. The thesis contains a complex analysis that confirmes material formability. Computer simulation verifies the part design, material and technological parameters of the forming process.
