Abstract

Forging dies, which are crucial for manufacturing automobile tripod housings, are frequently replaced owing to their extensive use under challenging conditions, leading to the disposal of many components and increasing manufacturing costs. The development of repair and remanufacturing technologies for high-hardness forging dies is a challenging. This study explores the on-site repair of tripod forging dies using wire arc directed energy deposition (arc-DED), assesses the hardness and tensile properties of remanufactured components, and compares them with the specified forging die requirements for on-site usability. A validated novel slicer is employed in remanufacturing experiments on a 9.8 % Cr die steel tripod-forging die. Results show the effectiveness of arc-DED in remanufacturing, surpassing the specified requirements by at least 111 HV and 61 MPa in hardness and tensile strength, respectively. Thus, this study presents a promising approach to reduce the manufacturing costs and environmental impact associated with the forging-die-component disposal.

基于线弧定向能沉积的汽车零件锻模原位再制造

锻造模具是制造汽车三脚架外壳的关键，由于其在恶劣条件下的广泛使用，经常需要更换，导致许多部件报废，制造成本增加。开发高硬度锻造模具的维修和再制造技术是一项挑战。本研究探讨了使用线弧定向能沉积（arc-DED）对三脚架锻模进行现场修复，评估了再制造部件的硬度和拉伸性能，并将其与指定的锻模要求进行了比较，以确保现场可用性。在对铬含量为 9.8% 的模具钢三脚架锻模进行再制造实验时，使用了经过验证的新型切片机。结果表明电弧-去毛刺在再制造中的有效性，其硬度和抗拉强度分别比规定要求高出至少 111 HV 和 61 MPa。因此，这项研究为降低与锻造模具部件处理相关的制造成本和环境影响提供了一种可行的方法。
