Description

It features small forging draft angles (0-3) and surface finishes of grade 6 or higher, significantly improving the dimensional accuracy and structural complexity of forgings. Currently, T-shaped connecting rods are commonly formed using forging processes.

[0003] Forging dies play a crucial role in the forging process: their cavity structure affects the final shape, size, and consistency of the product; dies restrict the direction of metal flow, and proper design can optimize stress distribution and avoid defects; furthermore, dies can reduce peak stress, make the load distribution more uniform, and reduce equipment load; additionally, the die structure directly affects the utilization rate of raw materials. In existing technologies, conventional dies used for forging T-shaped connecting rods consume a large amount of raw materials, and the flash rate of the forged products is also high, resulting in high overall production costs.
