stamping die preventive maintenance Introduction to deep drawing process One: Concept Deep drawing: pressing the sheet into a hollow part (the wall thickness is basically unchanged) Deep drawing process: the material on the plane (flange) is transferred to the side wall of the cylinder (box), so the outer dimensions of the plane change greatly Drawing coefficient: the ratio of drawing diameter to blank diameter “m” (deformation degree from blank to workpiece) Two: the main factors affecting the drawing coefficient Mechanical properties of materials (yielding strength—-elastic deformation; tensile strength—-plastic deformation; elongation coefficient; section shrinkage rate) The relative thickness of the material (T/D<1 D is the diameter of the blank) Number of…
