BÜKME KALIPLARINDA 0.75 MM KALINLIĞINDAKİ ÇELİK SAC MALZEMENİN GERİ ESNEME MİKTARLARININ BELİRLENMESİ

Bukme kaliplarinin sac metal endustrisindeki onemi buyuktur. Kaliptan cikacak olan parcalarin istenilen tolerans sinirlari icinde olmasi icin, bukme kaliplarinda bukulen malzemelerin geri esneme miktarlarinin bilinmesi de bir o kadar onem kazanmaktadir. Bu nedenle bu calismada bukme kaliplari ve bukmede geri esneme konusu arastirilmistir. Bukmede geri esneme miktarinin tespiti icin bir "V" kalibi tasarlanmis ve bu kalipta 0,75 mm kalinliktaki sac malzemelerin farkli acilarda ne kadar geri esneyebilecekleri tespit edilerek geri esneme grafikleri elde edilmistir. Geri esneme farkli kalipta, her acida 10' ar adet parca bukulmek suretiyle, kaliptan cikan parcalarin geri esneme miktarlari optik profili metre ile olculmustur. Deney sonuclari bilgisayar ortaminda excel programinin yardimi ile grafiklere donusturulmus ve degerlendirilmistir.
