介绍了实现９０°弯曲和小于９０°弯曲２副模具合在１幅弯曲模具内弯曲的关键技术，以及弯曲作弯曲边靠得很近时，弯曲过程中尺寸干涉技术问题的解决方法。
The key technologies to realize the bending of two molds with 90 ° bending and less than 90 ° bending in one bending mold are introduced, and the solution to the technical problems of dimensional interference in the bending process when the bending side is in close proximity is introduced.
