Bending and drawing
The document discusses bending operations in sheet metal manufacturing. There are two main types of bending: V-bending and edge bending. V-bending is done with a V-shaped die for low production, while edge bending uses a pressure pad and more complex dies for high production. When metal is bent, the inside of the neutral plane is compressed and the outside is stretched. After bending, springback occurs as the bent part partially recovers toward its original shape due to residual elastic energy.

BENDING OPERATIONS Springback in Bending Spring back = increase in included angle of bent part relative to included angle of forming tool after tool is removed Reason for spring back When bending pressure is removed, elastic energy remains in bent part, causing it to recover partially toward its original shape Spring back in bending shows itself as a decrease in bend angle and an increase in bend radius 07-02-2019 05:45 8
