    • PURPOSE: A drawing mold which can reduce the bending and spring-back phenomenon of a sidewall is provided to reduce the sidewall bending phenomenon and molded products spring back by gradually increasing bead force. CONSTITUTION: A drawing mold comprises a die(110), a punch(120), a blank holder(130), and a bead power control device(140). The die is ascended and descended. The punch is fixed to a rigid frame(101) arranged in the lower part of the die. The blank holder is lifted from the rigid frame. A material is provided to the blank holder through the die and blank holder. The bead power control device increases the bead power added in the material.
    • 目的:提供一种能够减少侧壁的弯曲和回弹现象的拉伸模具,以减少侧壁弯曲现象,并且通过逐渐增加胎圈力来使模制产品弹回。 构成:拉伸模具包括模具(110),冲头(120),坯料保持器(130)和胎圈功率控制装置(140)。 死亡是上升和下降的。 冲头固定到设置在模具的下部的刚性框架(101)。 坯料架从刚性框架上提起。 通过模具和坯料夹持器将材料提供给坯料支架。 胎圈功率控制装置增加材料中添加的胎圈功率。
