摘　　要：再制造工程的优势体现在节省原材料、节约能源、降低成本、环境友好等诸多方面。为提高模具寿命降低连杆生产成本,进行了连杆热锻模再制造试验。与传统方法相比,热锻模再制造将模具寿命提高了100%,显著降低了模具管理成本和模具成本。分析表明,选用优质模具材料,优化模具热处理和表面渗氮工艺是实施连杆热锻模再制造的核心技术。Reproducing engineering owns the benefits including raw materials saving, energy conservation, reduction of cost, environmental benign and etc. Reproducing experiment was carried out on hot forging dies for connecting rods, to improve the service life of dies and decrease the cost of rods. Compared to the conventional process, the reproducing process improved the service life of dies up to 100 %, which remarkably saved the costs of management and dies. It was concluded that the selection of the premium tool material and the process optimizations of heat treating and surface nitriding were the core techniques in the reproducing procedure.
