Abstract

Derin çekme, sac malzemelerin çekme kalıpları yardımıyla press kuvvetleri altında belirli derinlik ve şekillerde üç boyutlu kapların elde edilmesi işlemidir. Bu çalışmada, dikdörtgen geometriye sahip kapların açılı derin çekme kalıplarında deneysel olarak ve sonlu elemanlar metodu (SEM) ile sayısal olarak şekillendirilmesi araştırılmıştır. Bunun için kalıp boşluğu içine malzeme akışının kolaylaştırılması amacıyla matris/baskı plakası yüzeylerine α=0°, α=3°, α=6°, α=9°, α=12° ve α=15° açılar verilmiştir. Zımba ve kalıp köşe radyüsleri 8 mm sabit olarak alınmıştır. Deney malzemesi olarak 0,9 mm kalınlığında St37 çelik sac kullanılmıştır. Deneyler, 2500 N, 5000 N, 7500 N ve 10000 N baskı plakası kuvvetleri uygulanarak yapılmıştır. Açıların ve baskı plakası kuvvetinin limit çekme oranı, et kalınlığı ve kap hasarları üzerindeki etkileri deneysel ve sayısal olarak incelenmiş ve optimum zımba kuvveti belirlenmiştir. Elde edilen deneysel sonuçlar, ANSYS sonuçlarıyla karşılaştırılmıştır. Sonuç olarak, farklı açılara sahip dikdörtgen geometriye sahip çekme kalıplarında kalıp/baskı plakası yüzey açılarının artmasının geleneksel kalıplara göre daha yüksek limit çekme oranı sağladığı tespit edilmiştir. Deneysel olarak elde edilen sonuçlar ile sayısal sonuçların yaklaşık değerler olduğu gözlenmiştir.

Investigation of Deep Drawability of Rectangular Shaped Cups in Deep Drawing Dies

Abstract

Deep drawing is the process of obtaining three-dimensional containers of certain depths and shapes under pressing forces with the help of drawing molds of sheet materials. In this study, the numerical shaping of rectangular cups in angled deep drawing dies was investigated experimentally and by using the finite element method (FEM). For this purpose, die/blank holder surfaces have α=0°, α=3°, α=6°, α=9°, α=12° and α=15° angles in order to facilitate material flow into the die cavity. The punch and die corner radii are taken as 8 mm. St37 steel sheet with a thickness of 0,9 mm was used as the test material. The experiments were carried out by applying die/blank holder forces of 2500 N, 5000 N, 7500 N and 10000 N. The effects of angles and die/blank holder force on limit draw ratio, wall thickness and the damage of cups were investigated experimentally and numerically, and optimum punch force was determined. Obtained experimental results were compared with ANSYS results. As a result, it has been determined that the increase in die/blank holder surface angles in drawing dies with rectangular geometry with different angles provides a higher limit drawing rate than conventional dies. It has been seen that the experimental results and numerical results are approximate values.
