The ‘pre-design + optimization’ is one of the main methods to obtain appropriate cooling pipe parameters in hot stamping tools for satisfied quenching quality of hot stamping parts. Since good ‘pre-design’ can effectively reduce the workload of optimization, a novel pre-design method of cooling pipe parameters was put forward and applied in this paper. Firstly, the concept of pipe parameter window and its related building method were proposed, by which the domain of satisfied cooling pipe parameters, under certain quenching process and quality demand, could be obtained. Secondly, the pipe parameter window of drilled cooling pipes, suitable for flat die surface, was built based on the above method, and then used to pre-design the cooling pipes in flat die for application. Finally, the satisfied cooling performance of pre-designed cooling pipes demonstrated the validity of proposed method in guiding the pre-designing of cooling pipe parameters in hot stamping tools.
