Metal stamping parts generated when the bending over

(1) when the blanking stamping caused by burrs. To research cutting edge, and pay attention to check whether the blanking clearance is reasonable.

(2) cutting has washed pieces of double material and torsion deformation, lead to bad after bending forming, blanking blanking from location to tackle.

(3) bending instability caused by metal stamping parts. Mainly aimed at the U and V bending. Deal with the problem of stamping parts of the guide before bending, the guide, in the process of bending and bending process of medium pressure live material prevent stamping when bending slide is the key to solve the problem
