Otomotiv Endüstrisinde Kullanılan Derin Çekme Kalıplarında Yeni Bir Optimizasyon Yaklaşımı

Günümüzde otomotiv sektöründeki proje maliyetlerinin günden güne azalarak, karlılığın artması beklenmektedir. Sac şekillendirme süreçlerinde de bu doğrultuda ilerleyerek, daha karmaşık parçaları daha az operasyonda tamamlanması hedeflenmektedir. Bir operasyonda gerçekleştirilen karmaşıklığın artması, plastik şekil verme süreçlerinde daha fazla yırtık, incelme, çatlak problemleri ile karşılaşılmasına neden olmaktadır. Bu çalışmada karmaşık yapılardaki derin çekme parçalarında kuvvet, açınım boşaltmaları, açınım konumlaması gibi optimizasyonlarla yırtık, incelme, çatlak problemlerinin azaltılması amaçlanmıştır. Çalışma sonunda şekillendirme kabiliyetinin arttığı görülmüştür. Bu sayede de imalat süreçlerindeki hurda, hat duruş zamanı %90 oranında azaltılmıştır. Bu çalışma Ford Otosan çatısı altında yürütülmüştür.

A New Process Optimization Of Deep Drawing Part For Sheet Metal Forming In Automotive Industry

Drawing die complexity is higher than conventional stamping operations, nowadays. It needs to decrease stamping die operation numbers for a part to reduce project budget consumption. Therefore, frequency of tearing, thinning, crack occurrence increase while this amendment. Force, blank cutting, blank location on the drawing die and process optimization were investigated to decrease tearing, thinning and crack occurrence in Transit bodyside inner panels which have over 110 mm. deep drawing process. Formability was improved at the end of this study. Thus production scrap, stoppage time of stamping line were decreased over 90%. This study was conducted at Ford Otosan.
