A kind of bearing calibration of blade may further comprise the steps:
A, blow clean the dust in blade root and the framework, and remove the burr of blade datum level;
B, the framework on the blade is detected, carry out the inspection of profile from central region, the correction of surplus or opening are proofreaied and correct before and after determining, and will need in addition mark of the profile of proofreading and correct;
C, select suitable cushion block according to the width of blade profile, described cushion block upper surface is provided with U-shaped opening, and its two ends are the strong point, and the described strong point is made by copper product;
D, cushion block is placed on the presenting a theatrical performance as the last item on a programme of forcing press the pressure head of forcing press and cushion block central vertical;
E, the supporting point position of adjusting cushion block and the pressure point position of forcing press;
F, the pressure of controlling well carry out sectional stamping with forcing press to profile and proofread and correct.
Further, adopt pneumatic spray gun to blow down blade root and the interior dust of framework among the described step a, adopt sand paper or file to remove the burr of blade datum level.
Further, described step e Leaf Inner arc has surplus and during imperforation, the strong point of cushion block is at the Inner arc, and the pressure point of forcing press is at back of the body arc.
Further, when described step e Leaf back of the body arc had card base, the strong point of cushion block was at back of the body arc, and the pressure point of forcing press is at the Inner arc.
Further, when opening appearred in described step e Leaf, the pressure point of forcing press was at the Inner arc, and the strong point of cushion block is at back of the body arc, and cushion block tiltedly puts, and became 45 ℃ with blade.
Further, described forcing press is hydraulic press.
Beneficial effect of the present invention is: the bearing calibration of described blade is adopted the method for segmentation that profile is carried out punching press and is proofreaied and correct, two strong points distance is little, after the correction, rebound amount is little, a profile is carried out the correction of next profile after proofreading and correct and finishing again, after employing the method is proofreaied and correct, the blade profile printing opacity is good, meets the requirements.
