Abstract：

In order to reduce the stamping steps and production costs of the forklift wheel hub as much as possible, the improving method of the stamping process was put forward. It was a simplified drawing process with a pre-punching lightening hole of deformation Ф80 mm at the position of Ф130.5 mm on the wheel hub bottom. It was demonstrated that the stress state on the bottom of the cylinder was improved by pre-punching the lightening hole of deformation, which made the metal of the tube bottom flow to tube wall. Therefore the height of the cylinder was increased and the drawing process was reduced. The simulation analysis verification was realized by the sheet metal stamping simulation software Dynaform. The results show that shaped parts are obtained without wrinkling and cracking. At the same time, it is experimental that the improved stamping process can produce the qualified forklift wheel hubs.
