Abstract: As an important part in automobile engine, torque converter housing has diversified and complex shape characteristics and processing technology. However, about traditional torque converter housing production line, there are problems such as high consumption and low efficiency, low productivity depending on workers' operation and so on, which makes it an urgent need to transform to the direction of green and intelligent. Based on this, the design of intelligent clean manufacturing production line for torque converter housing is carried out. Combined with the problems of the existing production line, the intelligent clean manufacturing production line for torque converter housing is optimized, the design of the hardware system of the intelligent clean manufacturing production line for torque converter housing, the design of the processing technology of the split torque converter housing and the design of the process equipment system of the torque converter housing production line are completed. Taking the average production beat as an indicator, the production efficiency of the intelligent clean manufacturing line has been improved by 55.1%.
