Abstract：

For the change of temperature during the hot stamping production process of ultra-high-strength steel, in order to improve the stability of hot stamped parts and reduce the influences of temperature changes on the performance of parts, a general long-period intelligent control model was proposed, and the long-period factors in hot stamping production were focused on. Based on the sensing data from cyber-physical system, the die temperature and the cooling water temperature in the hot stamping process were optimally controlled by the on-line long-period intelligent control method. Through building a sensor network in the production line and monitoring and actively adjusting the die temperature and the cooling water temperature, the long-period intelligent control method not only realized the optimal control of the die temperature and the cooling water temperature, but also intelligently adjusted the production cycle to a more reasonable value, which was an effective dynamic control method. Thus, the long-period intelligent control is a useful supplement to the existing hot stamping production control system.
