Different forging 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, inspection of the size and surface defects of forgings; heat treatment of forgings to eliminate forging stress and improve metal cutting performance; cleaning, mainly to remove surface oxides; correction; inspection, general forgings must undergo appearance and hardness inspections, and important forgings It must go through chemical composition analysis, mechanical properties, residual stress and other inspections and non-destructive testing.
