Abstract：

The present production method of mixing blade in blender is free bending, and the blade will be shifted in the bending process because of the uneven force without a blank holder, so the bending precision of blade is affected greatly. The shape compensation in advance according to the slip can decrease or even avoid the shaping error, which can get an accurate slip quickly, and the quality and efficiency can be greatly improved. The blade slip was predicted by the numerical simulation about the bending process, and the bending experiment was carried out at the same time and the blade slip was measured. The variation trend of the calculated values and the measured values was generally in agreement with the measured values. The result shows that the slip value on the blade corner is larger and the slip value in the middle is smaller，and the error between them is stable through comparison. The simulated results after processing can represent experimental data generally, which shows that the finite element simulation method is effective in the prediction of the blade slip during bending.
