Abstract：

The traditional phosphating process commonly used for automotive extrusion parts has been gradually replaced by new lubricants. In order to match the market needs of lubrication system for new lubrication process, the product structure design was carried out. Guided by the design method of Six Sigma (6σ), the design scheme was conducted by the morphological matrix, and the three main equipments of heat treatment industrial furnace, transmission structure and lubrication structure were analyzed parametrically. Then, the morphological matrix was constructed to obtain 144 kinds of alternative schemes, and five typical schemes were selected based on theoretical research and actual enterprise research. Furthermore, the optimized scheme was conducted by the expert consistency evaluation method and mechanical design technical evaluation method, and the best solution was obtained. Finally, the design scheme was verified by the design principle of Six Sigma (6σ), and the No.5 scheme was determined as the best solution, namely, the radiant continuous heat treatment industrial furnace, the transmission structure of the chain mesh conveyor belt with the cycloidal pin wheel reducer, and the pneumatic multimotor stirring lubrication mechanism.
