Abstract：

Due to the influence of alternating stress during the actual production process, hot forging mold has complex stress conditions and a very harsh service environment. Therefore, based on the Archerd wear model, the wear coefficient K value of the wear model was calculated by comparing the finite element simulation result of a typical crankshaft forging die with the actual wear amount to obtain a modified Archerd wear model suitable for the hot forging production of crankshaft. Then, the die life was predicted by the modified Archerd wear model, and the wear and failure of the die were judged based on the machine vision system. The results show that the correction value of K is 1.425×10-7, and the agreement with the actual measured value is 91.47%. The predicted life is 6351 pieces, which is consistent with the actual production condition of 6400 pieces. Machine vision judgment is performed on the wear and failure die to verify the feasibility of machine vision technology in forging die wear detection.
