Method for replacing shear blade of trimming shear

The invention relates to a method for replacing shear blades of trimming shears, and belongs to the technical field of steel trimming equipment.The method comprises the steps that the shear blades are dismounted and mounted; the display gap value of the shear blade gap between the shear blades is adjusted to the target gap value; adjusting the display overlap value of the overlap amount between the shear blades to a target overlap value; measuring the real clearance value of the shear blade clearance between the shear blades; measuring the real overlap value of the overlap amount between the shear blades; if the target value is the same as the true value, replacement is completed; if the target value is different from the true value, correcting the display gap value and the display overlapping value according to the true gap value, the target gap value, the true overlapping value and the target overlapping value; repeating the steps until the target value is the same as the true value; by continuously correct
