Abstract：

Large mining pin-rail belongs to complex long axis forgings. Roll forging billet- two worktables die forging technology with hot die forging press was adopted in the pin-rail forgings forming. Rail plates on both sides of the pin-rail were mainly formed in pre-forging. Ring resistance wall was located in peripheral regions of the lugs pre-forging die cavity where the material filled hardly，then the metal would be urged to flow to lugs die cavity. Precision shaping of rail plates on two sides and forming of pin tooth in the middle were completed in final-forging. The FE model of forging process was constructed with finite simulation software of Deform-3D, and the coupled thermo-mechanical finite element simulation was conducted. Then the changing rules of temperature distribution, effective strain distribution and velocity field of material in the pin-rail forging process were analyzed. Pin-rail forgings were forged on a 80 MN hot die forging press, which as the main deformation equipment. The effect of pin-rail forgings forming is good, which verifies the truth of the simulation results.
