Correction process for adjusting heat treatment deformation of an arm lever portion

The invention discloses a correction process for adjusting heat treatment deformation of an arm lever portion. The correction process comprises the steps of: placing a deformed product in a containercontaining a cooling medium for cooling until the product reaches the martensite temperature and is cooled completely, taking out the product and air-drying the product for later use, putting the product into a salt bath furnace, starting the heat treatment, after the heated finished product is taken out the furnace, quickly putting the product into a press for correction; putting the corrected product into a material frame, and bringing the material frame vertically into a cold water tank; putting the product into the salt bath furnace again, starting the secondary heat treatment, after the heated finished product is taken out the furnace, quickly putting the product into a press for secondary correction; then vertically putting the corrected product into the cold water tank again, takingthe product out and dryin
