Özet:

 High strength and light high strength steels are widely used in the automotive industry. Springback is as important a problem as tearing and thinning in the shaping of high-strength sheets. In this study, the mechanical properties of SCGADUB1180 high-strength sheet were determined by performing tensile tests and the effects of punch speed, die angle, holding time, rolling direction parameters on springback were experimentally investigated in the V bending process. No research has been found in the literature on the shaping and springback behavior of SCGADUB1180 high strength sheet. As a result of the test results, as the punch speed increased, the springback values increased at 60, 90 and 120 bending angles. When punch speed increased from 3 mmsec to 10 mmsec at 60 bend angle, springback increased 1.87 in 0 rolling direction, 0.35 in 45 rolling direction and 9.78 in 90 rolling direction. When punch speed increased from 3 mmsec to 10 mmsec at 90 bend angle, springback increased 5.87 in 0 rolling direction, 0.55 in 45 rolling direction and 4.77 in 90 rolling direction. When punch speed increased from 3 mmsec to 10 mmsec at 120 bend angle, springback increased 27 in 0 rolling direction, 0.49 in 45 rolling direction, and 3.5 in 90 rolling direction. Springback values are lowest at 3 mmsec punch speed. When the holding time was increased from 0.2 s to 1 s, the springback value decreased by 5.56. The least springbacks were observed in the O rolling direction. The amount of springback increased with increasing die angle. The experimental results obtained will help to predict the springback behavior of high strength sheets and to understand their mechanical behavior in the bending process.

 Dayanımı yüksek ve hafif yüksek mukavemetli çelikler, otomotiv sektöründe yaygın olarak kullanılmaktadır. Yüksek mukavemetli sacların şekillendirilmesinde geri yaylanma, yırtılma ve incelme kadar önemli bir problemdir. Bu çalışmada, SCGADUB1180 yüksek mukavemetli sacının çekme testleri yapılarak mekanik özellikleri tanımlanmış ve V büküm prosesinde, zımba hızı, kalıp açısı, ütüleme süresi, hadde yönü parametrelerinin geri yaylanmaya etkisi deneysel olarak araştırılmıştır. Literatürde, SCGADUB1180 yüksek mukavemetli sacının şekillendirilmesi ve geri yaylanma davranışları üzerine araştırmaya rastlanmamıştır. Yapılan deney sonuçları sonucunda, zımba hızı arttıkça 60,90 ve 120 büküm açılarında geri yaylanma değerleri artmıştır. 60 büküm açısında zımba hızı 3 mmsnden 10 mmsn arttığında geri yaylanma, 0 hadde yönünde 1.87, 45 hadde yönünde 0.35, 90 hadde yönünde 9.78 artmıştır. 90 büküm açısında zımba hızı 3 mmsnden 10 mmsn arttığında geri yaylanma, 0 hadde yönünde 5.87, 45 hadde yönünde 0.55, 90 hadde yönünde 4.77 artmıştır. 120 büküm açısında zımba hızı 3 mmsnden 10 mmsn arttığında geri yaylanma, 0 hadde yönünde 27, 45 hadde yönünde 0.49, 90 hadde yönünde 3.5 artmıştır. 3 mmsn zımba hızında geri yaylanma değerleri en düşüktür. Ütüleme süresi 0.2 snden 1 snye arttırıldığında geri yaylanma değeri  5.56 azalmıştır. 0 hadde yönünde en az geri yaylanmalar görülmüştür. Kalıp açısının artmasıyla geri yaylanma miktarları artmıştır. Elde edilen deneysel sonuçlar, yüksek mukavemetli sacların geri yaylanma davranışlarının tahmin edilip, bükme prosesinde mekanik davranışlarının anlaşılmasına fayda sağlayacaktır.
