Forged shaft process and heat treatment

Different forged shaft methods have different processes. Among them, hot die forging has the longest process. The general sequence is: blank blanking; blank heating; roll forging blank preparation; die forging forming; trimming; punching; straightening; Intermediate inspection to inspect the size and surface defects of forgings.

Heat treatment of forged shaft is used to eliminate forging stress and improve metal cutting performance; cleaning is mainly to remove surface oxide; correction; inspection, general forgings must undergo appearance and hardness inspections, and important forgings must undergo chemical composition analysis, mechanical properties, and residual stress Wait for inspection and non-destructive testing.
