汽车侧围外板开卷落料模具的结构研究

摘要

本文主要研究汽车侧围外板的开卷落料模具结构，其中提到了两种常见的侧围落料模结构，一种传统的三个工步两个步距长度的开卷落料模，另一种两侧切角+中间切断的汽车侧围外板零件开卷落料模。通过对两种侧围落料模的结构及工作原理进行比较，得出各自的结构优缺点，便于今后汽车侧围开卷落料模的结构选择。%This paper mainly studies the automobile side wall plate decoiling fall die structure material, which referred to the two common side wall fall blanking die structure, a traditional three working step two step away from the unwinding of the length of the blanking die, another on both sides of the cut angle and cut in the middle of automobile side Wai plate parts of Decoil blanking die. Based on the two side around the structure and working principle of the die material, obtained the advantages and disadvantages of each structure, for the future of the automobile side Wai uncoiling of the die material falling.
