Some key process parameters in the deep drawing process have a significant impact on the deep drawing results.

The deep drawing coefficient, which is the ratio of the billet diameter D to the workpiece outer diameter d, is an important indicator for measuring the difficulty of deep drawing. The smaller the deep drawing coefficient, the greater the degree of deformation, and the easier it is for the billet to crack, often requiring multiple deep drawings to complete the forming of the workpiece.

The thickness t of the sheet also has a significant impact on the deep drawing process. Thicker sheets have higher deformation resistance and require greater deep drawing force during the drawing process, while also improving the strength and rigidity of the workpiece; Although thinner sheets have lower drawing force, they are prone to defects such as wrinkling and tearing.

In addition, the drawing speed cannot be ignored. Excessive drawing speed can deteriorate the fluidity of the material, leading to defects such as cracks on the surface of the workpiece; Slow drawing speed can affect production efficiency.
