Original abstract
The most common problem in area of bending technology is problem of achieving accurate and repeatable bending angle. This problem is caused by elastic springback. Springback can be defined as an elastically-driven change of shape of the deformed part upon removal of external loads. This phenomenon is observed also in other sheet metal forming processes. In this paper were presented results for different bending curvature and its influence to the springback amount springback. Difference between springback amount caused by Bauschinger effect was also discussed.
Czech abstract
Nejčastějším problémem v oblasti technologie ohýbání je problém dosažení přesného a opakovatelného úhlu ohybu. Tento problém je způsoben odpruženími. Odpružení může být definováno jako pružně řízená změna tvaru deformované části při odstranění vnějších zatížení. Tento jev je pozorován i u jiných procesů tváření plechů. V tomto článku byly prezentovány výsledky pro různé poloměry ohybu a jejich vliv na velikost odpružení. Rozdíl mezi hodnotou odpružení způsobené podle Bauschingerova efektu byl také pojednán.
