板料和块体组合成形（SBMF）工艺是指采用典型的块体成形操作进行板料成形。因此，同时存在二维和三维应力和应变状态。此外，在板平面外形成的局部形状元素具有板厚度的大小。本文论述了镦粗/侧挤和拉深/镦粗的工艺组合。已经表明，使用传统的模具系统，不充分的模具填充几乎是不可避免的。并对新开发的成形方法的前景进行了讨论。(C)2011年CIRP。
The class of combined sheet and bulk metal forming (SBMF) processes denotes the forming of sheet metals with typical bulk forming operations. As a consequence, simultaneous 2D and 3D stress and strain states are present. Furthermore the local shape elements formed out of the sheet plane are in the magnitude of the sheet thickness. This paper deals with process combinations upsetting/lateral extrusion and deep drawing/upsetting. It has been shown that an insufficient mould filling is nearly inevitable using conventional tooling systems. Hence, the prospect of newly developed forming approaches will be discussed.
