Copper alloy extrusion can produce flat,rod,wire,pipe and profile products,which need frequent cleaning and maintenance of the mold in the production process,need to detect the use of the mold,whether the mold needs to be replaced;Due to the diverse shape of the die hole,small size and high tem-perature (500°~650°),it is currently manual detection,and the efficiency and accuracy are low. The de-velopment of online intelligent detection system of mold status,the use of robots instead of manual work,improve the quality and efficiency of equipment operation,reduce the labor intensity and risk of personnel,and realize the efficient,intelligent and "unmanned" operation of copper extrusion production line.
