Analytical part deep drawing a straight wall uneven how to solve?

by:Fortuna     2021-01-31
For engineers often design of deep drawing parts, conical or straight wall form deep drawing parts, how many are in the process of making the waist wrinkling or straight wall part wrinkled factors, and we also passed some detours, summarizes some experience to share: at the beginning of the deep drawing most of the materials are in a suspended state, pressure is too small or die fillet radius is too big, make radial force smaller tangential stress under the action of losing stability and wrinkle, we can use to increase pressure or USES the rolling steel structure, reduce the die radius or slightly increased to make the material thickness to solve, this method can be suitable for deep drawing of conical; For the straight wall deep drawing parts, punch without design and produce air breather, make its surface deformation due to compressed air appear uneven phenomenon, we must increase the vent; And the material springback effect also can make the rough on the surface of the deep drawing, the final need to increase the plastic process; For did not adjust because of mold, such as poor clearance in deep drawing, mold clearance adjustment must be suitable for production again.

Details: sharing details of stamping processing industry: precision metal stamping parts figure how to draw, please be aware that this several steps
