Abstract

Abstract Fixture hardening is the process of choice when thin-walled, carburized gears need to be heat treated with minimal distortion. Only a few publications have studied and described the phenomena taking place in carburized gears during a fixture hardening process. An integrated approach is proposed to improve the design of hardening fixtures and introduce new strategies and instrumentation to better understand and control the process. The proposed approach is to tightly integrate the knowledge in metallurgy, numerical simulation, process control, and machine design areas to mutually compensate and overcome the current limitations in each single area. An instrumented fixture is designed for a reference gear and tested on an industrial quenching press. The signals from the fixture are combined directly with the signals from the quenching press, recorded, and used to validate and improve the numerical simulation models. Metallurgical simulations are used to predict temperature distribution, phase transformations, distortion, and to identify new process strategies.

刀具夹具硬化仿真及工艺优化设计
摘要当薄壁、渗碳齿轮需要以最小的变形进行热处理时,夹具硬化是一种选择。只有少数出版物研究和描述了在夹具硬化过程中发生的渗碳齿轮现象。提出了一种综合的方法来改进强化夹具的设计,并引入新的策略和仪器来更好地理解和控制过程。提出的方法是将冶金学、数值模拟、过程控制和机器设计等领域的知识紧密结合起来,相互弥补和克服当前每个单一领域的局限性。为参考齿轮设计了一种仪器夹具,并在工业淬火压力机上进行了试验。来自夹具的信号直接与来自淬火压力机的信号相结合,记录并用于验证和改进数值模拟模型。冶金模拟用于预测温度分布,相变,变形,并确定新的工艺策略。
