Effect of Mandrel Exchange on the Precision Forging of Spur Gear
In order to reduce the spur gear precision forging load and prevent load to rise sharply in final forging, on the basis of analysis the distribution of contact pressure of cylinder upsetting, mandrel exchange technology is put forward. As a result, the material always has free space to flow. The tool-set and experiment scheme are designed, finally, the scheme is further validated by Deform-3D, and the results show that the validity of mandrel exchange technology to reduce the load in gears precision forging.
