The cold forging process of LED radiator was simulated and analyzed by software FORGE-3D, and the change laws of forming loads and mold wear were obtained in the cold forging process for 1050 aluminum alloy parts. Based on numerical simulation and orthogonal experiment, the influences of friction factor, fillet radius of bridge, extrusion speed and flash thickness of forgings on the forming loads and mold wear were analyzed. The results show that among the four factors, the flash thickness has the greatest influence on the forming loads, and the extrusion speed has the greatest influence on the mold wear. Considering the simulation results of four factors comprehensively, the optimal scheme is determined with the friction factor of 0.06, the extrusion speed of 5 mm·s-1, the flash thickness of 0.6 mm, the fillet radius of bridge of 1.5 mm, and the above study provides a reference for practical production of high-power LED radiator parts and similar parts.
