In this study, different blank shapes obtained from

anisotropic aluminum sheet has been investigated by drawing in the

form of square cup. No any failure (tearing and fracturing) occured

in the drawn cups. Namely, they are useable. The results shown that;

optimum blank shape reduces scrap metal and costs but also, leads to

slightly wrinkling and bad surface quality. There are more scrap

metal and costs in the cups obtained from the otherblank shapes due

to greater earing and projection but, the surface quality especially in

the corners of the cups becomes better.

ALÜMİNYUM KARE KABIN DERİN ÇEKİLMESİNDE TASLAK MALZEME ŞEKİLLERİNİN DEĞERLENDİRİLMESİ

Öz

Bu çalışmada, anizotropik alüminyum sactan hazırlanan değişik taslak malzeme

şekilleri kare kap biçiminde derin çekilerek incelenmiştir. Çekilen tüm parçalarda

herhangi bir yırtılma/kopma meydana gelmemiş yani kullanılabilir durumda elde

edilmişlerdir. Optimum taslak malzeme biçimleri ile çekilen kaplarda hurda malzeme

miktarı ve buna bağlı olarak maliyetler azalmakta ancak, hafif buruşmalar meydana

gelmekte ve bu nedenle de yüzey kalitesi bozulmaktadır. Diğer taslak malzeme

şekillerinden elde edilen kaplarda ise, kulaklanma/dalgalanma oldukça fazla

olduğundan hurda malzeme miktarı ve buna bağlı olarak maliyetler artmakta fakat

özellikle köşelerdeki yüzey kalitesi daha iyi elde edilmektedir.
