Bulk forming technology of pin connector
Kříbala, Milan ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
The Bachelor’s thesis deals with the production of the coupling pin cold bulk forming with focus heading and extrusion. The part will be made of structural steel 11 320 5R. The size of the production is about 700 000 piece per year. The two processes was chosen for four forming operation. From the technological calculations were set forming by force 465 kN needed to select a suitable forming machine. Automatic machine TPM 8-A was elected due to force 1000 kN. The drawing documentation is part of the work. Extrusion tools are made of tool steel 19 830. One piece costs 0,6 Czech crowns – this calculation was in the technical-economic assessment.
Line for manufacturing parts for car engine volume thermoforming
Smola, Jiří ; Humlíček, Jaroslav (referee) ; Omes, Jiří (advisor)
The aim of this diploma thesis is to design valve production line for combustion engines by volume forming with heat. The production of line will be 2 500 000-10 000 000 pieces per year. In the introduction of this thesis are described production technologies. Next part is about design of production lines and description of each machine for each technology. Then are made the basic calculations for designe for each machine.
Production of shaft
Jančík, Petr ; Štroner, Marek (referee) ; Císařová, Michaela (advisor)
The bachelor's thesis is classified under the field of Engineering Technology and proposes a process for the production of a shaft made of steel 12 050 by combined extrusion. The material in question can be used, for example, for parts of mining machines, larger gears, pins or screws. In accordance with the acquired findings on the issue of volume forming, the production of the component was designed for two forming operations. A block with a diameter of 55 mm and a length of 146 mm was chosen as a semi-finished product. The production was designed on a Schuler automatic machine, which is a part of the company Metaldyne Oslavany, with a nominal force of 2 000 tons and a height of 7 meters in a series of 100 000 pieces per year.
Production of cold forging parts
Jedovnický, Jan ; Samek, Radko (referee) ; Špaček, Jindřich (advisor)
A project developed during a magister´s study of a program M-STM Mechanical engineering and industrial management brings in a proposal of a technology of cold forging part out of 12 040 steel. The forging on a multi-stage processual automatic machine TPZK 25 with nominal forming power 5000 kN was projected based on consultations, study of literary resources a calculations.
A study of upsetting tests
Chludil, Petr ; Šlais, Miroslav (referee) ; Podaný, Kamil (advisor)
Upsetting, or pressure tests are in an engineering practice used for determining the effect of the pressure load on material properties. They determine the values of deformation resistance and formability of tested materials. The usability of upsetting tests is even expanded with different kinds of execution, shapes of test samples and kinds of used test machines. Upsetting tests are then one of the most important and most variable kinds of tests that are used for the examination of mechanical properties of materials in an engineering practice.
Bulk forming technology of sandwich coil insert
Šíma, Vojtěch ; Kudláčová, Barbora (referee) ; Forejt, Milan (advisor)
The project elaborated in a frame of Master‘s degree branch M-STG focuses on the design of a technology of sandwich coil used for connecting the aircraft floor sandwich panels to the fuselage bulkheads. The product is made of a lightweight aluminium alloy AlMn1. Combined cold extrusion with upsetting of the flange was chosen as the most fitting technology due to the manufacturing requirements and production series size of 120 000 pieces per year. The component is manufactured from a block blank in three operations by a progressive forming machine TPM 8-A with a nominal force of 1000 kN from Šmeral Brno a.s. producer. Within the project, tools for the production of the part were designed and also technical calculations for individual operations and technical and economic evaluation of production were made. The price of the component is estimated to be at least CZK 7,33.
Design of Coupling Pin Production
Blažek, Matěj ; Podaný, Kamil (referee) ; Řiháček, Jan (advisor)
Bachelor’s thesis is aimed production of pin, made from steel 11 320-5R. This piece is in accordance to serial production 500 000 pieces year -1 made by cold bulk forming. Specifically it is about heading and forward extrusion. From two production variant was chosen the one with lower strain. By calculations there was set the power needed for production that equals Fc= 368,5 kN. Because of this power there was chosen a machine AKP 3-5 from company Hatebur. In the next step there was designed method that is in the attachment to the thesis. Final step was a control whether the idea of production by simulation is correct or not.
Manufacturing of a Pin
Glatter, Jiří ; Forejt, Milan (referee) ; Řiháček, Jan (advisor)
The work presents a proposal for the technology of production of a pin of gear assambly.The pin is used to position the wheel in a tapered roller bearing. Pin is made of 11 320.3 steel (11 320 5R), which is suitable for cold forming. Based on the study of cold forming and calculations, the methods of upsetting and extrusion were chosen. Most often, several methods are used for fabrication, which are mediated by a combined tool. It can also be made by any of the machining methods.
Forming technology production of window hanger.
Štejnar, Radek ; Šlais, Miroslav (referee) ; Forejt, Milan (advisor)
An objective of the bachelor’s thesis is the solution of forming technology production of window hanger by means of backward extrusion and elaboration of study concerning cold bulk forming. Required component is made of material ČSN 41 1320 5R and rounded chock with dimension of 14,6h9 - 25,3 mm is selected as semifinished product for production. Generally 2 alternatives of technology process were assessed whereas technological and strength calculations are executed utilizing computing support of TVÁŘENÍ and OPTIM97 software. Component is produced within 4 operations including cutting of wire. Multi-stage cold forming press TPZK 25 made by ŠMERAL a.s. Brno producer was chosen for designed technology. Production tools are made of high speed tool steel 19830.
