Earing cup drawing
WebThe deep drawing and tear-off test to Engelhardt is a method used for the determination of sheet metal forming properties. A cup is drawn from a circular specimen, and the die movement is continued until the bottom of the drawn component tears off. The necessary drawing force and force required to cause the bottom to crack are measured. WebExercise 8 Idler Pulley.

Webanisotropy determines the average cup height of the extra deep draw. The planar anisotropy determines the extent of earring. For optimal drawability, a combination of a high 4 value and a low ΔR value is necessary [17]. Ears are formed at the flange of the cup using the deepest drawing possible [18]. Das et WebEaring is a problem characteristic to deep drawing. Earing is the formation of wavy edges at the open end of the drawn cup. These are usually trimmed. The anisotropy of a …
