一种新型的四角弯曲冲孔复合模结构

摘要

结合支撑托架冲件的具体案例,阐述了一种新型的四角弯曲冲孔复合模结构.该结构通过采用浮动式的弯曲凸模,能够保证先后两次U形弯曲和冲孔依次进行,且冲孔时消除了弯曲变形的发生.该结构能够保证弯曲件上孔及孔间距的精度,具有一定的独创性.%Based on the specific case of support bracket stamping, in this paper, a new type of structure of four bent corners bending & piercing compound mold is stated. By using floating bending punch, this structure can guarantee that it has two U bending and piercing in turn and the bending deformation has been eliminated when piercing happens. This structure can also guarantee the hole spacing accuracy of bending parts, and has some originality.
