Numerical simulation and parameter optimization of cooling water channel of hot stamping die for door sill reinforced beam
Taking the hot stamping door sill reinforced beam as an example,the finite element mod-el of the flow field and temperature field of the cooling system of the hot stamping forming die were established,the distribution characteristics of temperature field in hot forming process of high strength steel was analyzed by using simulation software and orthogonal experimental design method.The results showed that the diameter of the cooling water channel,the distance from the water channel to the working surface and the distance between the water channels would affect the cooling effect of the hot stamping die,the parameters of the cooling water channels of the hot stamping die were optimized based on actual production factors.
