Heat shields are vehicle components that prevent transferring overheating that occurs in vehicle components at high temperatures to neighboring elements and vehicle body. Embossing is a sheet metal forming process for producing bulged designs by means of matched male and female roller rigid dies. After embossing process, embossed sheets are formed with the helping of molds according to the shape of vehicle component that will be kept away from overheating and in this forming process, some bulged designs are compressed. In this paper, for researching this compressed process, the embossed sheets are compressed with upper and lower rigid platens and this process entitled as restoration process. The purpose of this study is to investigate the effects of restoration process on the yield, tensile and bending strengths.

Isı kalkanları; yüksek sıcaklıkta, araç elemanlarında meydana gelen ısınmayı komşu parçalara ve araç gövdesine iletmeyi önleyen araç elemanlarıdır. Bu elemanlar; desenleme işlemi adı verilen üretim yöntemi vasıtasıyla üretilmektedir. Desenleme işlemi; rijit ve dönel merdaneler yardımıyla, levha metalin kabartılması işlemidir. Levha metal desenleme işleminden sonra, muhafaza edilecek parçanın üzerini kaplayacak şekilde kalıplar vasıtasıyla şekillendirilir. Bu esnada desenleme işlemiyle elde edilen kabartılarda ezilme işlemi gerçekleşir. Çalışma kapsamında bu işlemi elde etmek amacıyla; Al 1050 malzeme kullanılarak desenleme işlemiyle üretilen metallere, iki rijit plaka arasında ezme işlemi gerçekleştirilmiştir. Bu işleme literatürde yenileme işlemi denilmektedir. Bu çalışmanın amacı; yenileme işleminin akma, çekme ve eğilme davranışı üzerindeki etkilerini karşılaştırmaktır.
