Sheet metal bending is, bar, pipebending and profiles some perspective and shape of the stamping process. This study is the reeds blanking bending of progressive die design. First analysis, determined the best technology processing technology, and for process calculation, according to the size of workpiece and structural relationship, for instance in bending tooling design process of the determination of for rebound value. Major structural parts of the design calculation and strength check。 Finally and determine the blanking, bending the structural type of progressive die for parts, the design and check, and reasonable chose press.
