Summary of the invention
The object of the present invention is to provide a kind of bearing calibration of blade, adopt disposable punching press to correct to solve existing blade, rebound amount is comparatively large, makes product can not the problem of composite demand.
The object of the invention is to be achieved through the following technical solutions:
A bearing calibration for blade, comprises the following steps:
A, the dust blown clean in blade root and framework, and remove the burr of blade datum level;
B, the framework on blade to be detected, carry out the inspection of profile from central region, determine the correction of front and back surplus or opening corrects, and the profile corrected will be needed to be marked;
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 up of 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 adjustment supporting point position of cushion block and the pressure point position of forcing press;
F, pressure of controlling well, carry out sectional stamping correction with forcing press to profile.
Further, in described step a, adopt the dust in pneumatic spray gun blowing blade root and framework, adopt sand paper or file to remove the burr of blade datum level.
Further, described step e Leaf Inner arc have surplus and imperforation time, the strong point of cushion block is at 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 has a card base, the strong point of cushion block is at back of the body arc, and the pressure point of forcing press is at Inner arc.
Further, when opening appears in described step e Leaf, the pressure point of forcing press is at Inner arc, and the strong point of cushion block is at back of the body arc, and cushion block is tiltedly put, and becomes 45 DEG C with blade.
Further, described forcing press is hydraulic press.
Beneficial effect of the present invention is: the bearing calibration of described blade adopts the method for segmentation to carry out punching press correction to profile, two strong points are apart from little, after correction, rebound amount is little, after a profile corrects and terminates, then carry out the correction of next profile, after adopting the method to correct, blade profile printing opacity is good, meets the requirements.
