Production of filter cup
Míka, Tomáš ; Štroner, Marek (referee) ; Podaný, Kamil (advisor)
This work is concerned with the design of producing a filter cup made of material 17 240 (1.4301), 0,5 mm thick and the series 100 000 pcs/year, used in the lever of the espresso machine. The method of conventional deep drawing without wall thinning was chosen as the most suitable technology for the production of body cup. Utilizing calculations, an initial semi-product of circular shape with a diameter of 92 mm was determined. By means of technological and constructional calculations a single operation tool was designed, with the upper blank holder and knockout, which is intended for use with a double-acting press. Its functional parts are made of material 19 436. According to the calculated total force a double acting hydraulic press CTH 250 was chosen.
