Abstract: To improve the powder metallurgy forming quality of VVT umbrella-shaped oblique ribbed sprockets, Fe-Cu-C-MnS powders were used to investigate the effects of different compaction strategies on the density distribution and forming damage of green compacts through composition optimization and finite element simulation. The optimized powder formula was determined as Fe-2.5Cu-0.8C-0.4MnS. Four compaction models were established using Deform software to compare the density uniformity and damage characteristics under forward/reverse and same/opposite direction compaction modes. The results indicate that the scheme combining opposite-direction compaction and reverse forming achieves uniform powder filling with a minimum relative density difference of 0.006 and the lowest cumulative damage value, exhibiting the optimal forming performance. Practical production verification confirms that the simulated density distribution agrees well with experimental results, with a maximum error of only 0.94%. This study provides an effective technical reference for the manufacturing of high quality powder metallurgy automotive components.
