Abstract

In the present study, billet is designed by utilizing the flow relief-hole principle to improve the dimensional accuracy during the cold precision forging of helical gear. A three-dimensional FE simulation was carried out to analyze the deformation features of billet with different initial diameter of relief-hole under the commercial software DEFORM 3D. When the diameter of relief-hole d0 increases, the forming load decreases and the unfilled portions at the teeth top contacting with the punch increase. The deform mode of relief-hole, the variation trend and the distribution of effective strain are different under different diameter of relief-hole when compression ratio s varies.
