Abstract: This article was the progressive die design of passenger car door plate for punching and blanking. Analyzed Parts of shape, size, and precision process, determined the reasonable process scheme and the number of processes. Determined the size of blank and reasonable layout, drew layout. Calculated punching force, cutting force, stripping force, pushing force, and total punching pressure, determined the center of pressure. Calculated the main structure size of parts. Determined structure of convex and concave die, and drew the drawing of parts, designed positioning parts, pressing parts, unloading parts. Designed Fixed parts, selected other standard parts. Finally, used CAD and Pro-E to draw 2D and 3D assembling drawings, and generated explosive view.
