Abstract

Uzun içi bos parçalarin (5), özellikle de eksantrik millerin, sadece alet edevatta ve üretim asamalarinda tasarruf edilmesiyle kalmayip, ayni zamanda üretimin de artmasi sayesinde ucuza mal olmasi için, yüksek iç basinçla biçimlendirme yoluyla içi bos bir milden (5) öyle bombeler ya da mil dirsekleri (6) bir parça halinde meydana getirilirler ki, bombeler (6) biçimleri ve/veya konumlari bakimindan çok sayida asamada sekillendirilebilme özelligine sahiptir.Long hollow parts (5), such as camshafts (5), by means of high internal pressure shaping, to not only save money on tool and production stages, but also because of the increase in production, with high internal pressure. The shaft elbows (6) are formed in one piece that the bombs (6) have the feature to be shaped in many stages in terms of their shapes and / or positions.
