Stamping parts manufacturers share: drawing a flanging defect analysis

Well-known flanging is one of the basic process of deep drawing stamping forming, flanging is divided into flanging around the inner and outer edge flanging, carried out on the workpiece hole flanging called of flanging, or simply for the double hole; Outer edge of stamping flanging is called outer edge flanging, the author study together with everybody today after deep drawing parts flanging defect analysis; 1, deep drawing stamping straight flange flanging deformation analysis: double side without deformation 'stretch flanging and shrink flanging, the edge part is deformation, is removed by the mould, the shape change, this change is not only the change of perspective, including its ridge, overall shape will have changed' 2, ridge preventing countermeasures to change ( 1) Adding stiffener in flanging place, increase its rigidity '( 2) Whether vice 'long flanging, or shrink flanging, try to reduce residual stresses in the 'with elastic deformation, when the external load are removed, the plastic deformation of preserved, and elastic deformation can disappear completely, make the change shape and size of flanging and do not agree with mold size, this phenomenon is called springback' 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts?
