The basic working principle of automatic installation of intumescent embedded parts was described. Through CNC and related builtin PLC control motors and other equipment, the movement of the working platform and the continuous stamping of the intumescent embedded parts were achieved. The specific mechanical movement scheme and the whole set of CNC device control process were put forward. The system has the advantages of simple operation, stable operation and smooth, safe and reliability. Not only the installation accuracy of embedded parts is ensured, but also the installation time is saved and the installation efficiency is improved.
