大直径球形封头冲压展开下料尺寸的计算

Calculation of the blank expansion and size for spherical head with big diameter

在石油化工设备压力容器制造中,对于分瓣成形封头的质量控制关键是封头展开下料毛坯尺寸展开计算和冲压成形环节,文中对大直径球形封头冲压展开下料尺寸计算并加以阐述.

In the fabrication of pressure vessels for petrochemical equipments,the keys to quality control of sectional head are the blank expansion size calculation and stamping forming. The blank expansion size of the spherical head with big diameter head is calculated and introduced.
