Abstract：

The paper analyses the extrusion force of Aluminum alloy(LC4) tube workpiece with thin-wall in the process of extrusion forming.Using upper-bound method to solve the stress of die by deformation hodogragh and deformation rigid block,puts forward the limit forming condition of such parts and deduces the simplified engineering calculation method.
