Knowledge of structural design of sheet metal parts (IV): Configuration criteria of stretched parts
Configuration criterion of deep drawing parts a. The shape of drawing parts shall be as simple and symmetrical as possible. b. The size proportion of each part of the drawing part shall be appropriate, and the drawing parts with wide flange and large depth shall be avoided as far as possible. (d convex > 3D, H ≥ 2D) because such parts need more drawing times. c. The fillet radius of deep drawing parts shall be appropriate, and the fillet radius shall be larger as far as possible, so as to facilitate forming and reduce the number of deep drawing. (1)…
