Production of HTHT32 / 40 GI Double Elbow
Kříbala, Milan ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The diploma thesis deals with the design of an injection mold for manufacturing double elbow, which finds its use in the siphon assembly. The part will be made of polypropylene with the trade name Tatren HT 25 11. The production batch size is set at 100,000 units in 3 months. Firstly, the analysis of the part is done including a detailed specification of its function and criteria that must be met by the component. Furthermore, a suitable technology for the production of the part is chosen. The theory of injection molding and mold design is made on the basis of the chosen injection technology. Subsequently, in the practical part is made a complete design of injection mold including technological calculations and simulations. An injection molding machine is chosen for the proposed injection mold. The conclusion of the thesis consists of technical - economic evaluation of the production of double elbow.
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.
