高强度钢热成形的核心技术包括模具结构设计和温度控制系统设计两部分,而板料加热变形后的淬火和冷却速度是该工艺成败的关键。因此,亟须研发能实现最佳淬火和冷却工艺的模具及相应的温度控制系统。以带凸缘的盒形件为研究对象,首先计算了热成形模具的凸、凹模圆角半径和凸、凹模间隙,然后进行了热成形凸模、凹模以及压边圈具体结构和冷却水路的设计,最终研发出了热成形模具温度控制系统的自动控制方案和装置。
The core technology of high-strength steel thermoforming includes the design of mold structure and the design of temperature control system. The quenching and cooling speed after the sheet is heated and deformed is the key to the success or failure of the process. Therefore, there is an urgent need to develop molds and corresponding temperature control systems that will achieve optimum quench and cooling processes. Taking the box with flange as the research object, the convex and concave fillet radii of the thermoforming mold and the gap between the convex and the concave mold were calculated first, and then the specific structure of the hot forming punch, the concave die and the blank holder The design of cooling waterway, and finally developed an automatic control scheme and device for the thermoforming mold temperature control system.
