热冲压是用于制造轻质结构产品（例如轻质车辆）的热成形工艺之一。了解热冲压工艺的特性对于设计和优化工艺条件、模具和工具是重要的;然而，迄今为止，该工艺的特性，例如产品性能和模具温度之间的关系以及产品性能和冷却速率之间的关系以及回弹量之间的关系，还没有一致或精确地阐明。本文提出了一种新的评价方法，用于衡量热冲压条件对产品性能的影响，作为工艺参数的函数。该方法利用热成形模拟器，该模拟器是具有反馈温度控制和受控冷却的精密压力机，并且允许了解热冲压过程的各种特性。在这里，所提出的方法的基本结构，并将其应用到表征的热冲压过程中的高强度钢板，如评价产品性能的变化时，不同的成形条件和工艺参数，显示和讨论。
Hot stamping is one of the hot forming processes for manufacturing products of lightweight construction such as lightweight vehicles. Knowledge on the characteristics of the hot stamping process is significant in designing and optimizing the process conditions, dies and tools; however, until now, the characteristics of this process, such as the relationships between a product property and die temperature and between a product property and cooling rate, and the springback amount, have not been clarified consistently or precisely. A new valuation method used to measure the effects of hot stamping conditions on product properties as a function of process parameters is proposed in this paper. This method utilizes a hot forming simulator, which is a precision press with feedback temperature control and controlled cooling, and permits to know the various characteristics of the hot stamping process. Here, the basic construction of the proposed method is presented, and its application to the characterization of the hot stamping process of high-strength steel sheets, such as an evaluation of the changes in product properties upon varying the forming conditions and process parameters, is shown and discussed.
