Manufacturing of eye
Práce se zabĂ˝vá návrhem technologie vĂ˝roby oka, kterĂ© bude vyrábÄ›no zápustkovĂ˝m kovánĂm z nĂzkolegovanĂ© oceli 13 242. RoÄŤnĂ produkce je stanovena na 300 000 kusĹŻ. Na základÄ› literárnĂ studie problematiky a vĂ˝poÄŤtĹŻ bude vĂ˝kovek zhotoven pomocĂ bucharu, a to nÄ›kolika Ăşdery v dokonÄŤovacĂ dutinÄ›. Vzhledem k vĂ˝poÄŤtĹŻm kovacĂ práce je zvolen pneumaticko-hydraulickĂ˝ buchar KHZ – 2A o jmenovitĂ© energii 20 kJ. Zápustka je vyrobena z nástrojovĂ© oceli 19 663 tepelnÄ› zpracovanĂ© podle vĂ˝kresovĂ© dokumentace. Technicko-ekonomickĂ© zhodnocenĂ bylo zaměřeno na vĂ˝poÄŤet nákladĹŻ na materiál polotovaru (3 323 109,40 KÄŤ) a ceny kovacĂch nástrojĹŻ pro roÄŤnĂ produkci (930 000 KÄŤ).The project follows up design of technology manufacturing of eye, which will be made by drop forging from low-alloyed steel 13 242. Yearly production is set on 300 000 pieces. Pursuant to of the literary pursuit problem and calculations will be the forging made on a hammer with several hits in the finishing hollow. Regarding to calculations of forging work is elected pneumatic-hydraulic power hammer KHZ – 2A with energy of 20 kJ. Die is made of tool steel 19 663 heat-worked according to drawing documentation. Technical and economical evaluation was aimed on a calculation of production expenses of semi-produced material (3 323 109,40 CZK) and on price of the forging machines for yearly production (930 000 CZK).
