摘要
叉车货叉失效方式主要表现为塑性变形超差,脆性断裂和早期疲劳断裂。为保证货叉的机械性能与工艺性能,材料合碳量以0.3～0.4％为宜,推荐采用35CrMo钢。在备料、锻造、热处理、焊接等工艺过程中,应严格保证质量要求。
Fork failure of a forklift truck mainly takes a form of plastic deformation exceeding allowable limit,fragile breakage and early stage fatigue breakage. In order to ensure mechanical performance and technologicalfeatures of a fork, a material with 0.3-0.4% carbon content is appropriate, 35CrMo steel is recommended.Strict quality control is required in the process of cutting, forging, heat treatment and welding.
