Distribution of Shrinkages During Dressing Off of Sheet Metal for Deep Drawing

  • Yu. B. Faleev


In the production of sheet steel for deep drawing, dressing off is the final technological operation with the help of which the following problems are solved: 1) the flow stage is eliminated and the formation of slip bands during stamping of parts from sheet steel is thereby eliminated; 2) the mechanical properties of the steel are changed, and the sheet material becomes anisotropic, which promotes increased stability in the drawing of parts of complex form [3,4]; 3) it serves as a means for obtaining sheets of the required profile, and decreases divergence in the sheet thickness, which improves the technological properties of the sheet metal. In [1,2] it was shown that the deformation age-hardening of dressed steel occurs considerably more slowly in comparison with age-hardening of steel after dressing with multi-roller dressing machines and stretching of the sheet to the elastic limits with stretching machines.
