汽车轴类件是汽车传动和承载的关键基础件,我国传统的加工方式以锻造和切削成形为主,国外发达国家主要采用锻造成形,材料利用率和生产效率低、能源消耗大。随着汽车工业的发展,轴类零件需求巨大,其成形制造的高效节能,提高材料利用率,对实现绿色制造意义重大。
楔横轧是一种轴类零件成形的先进技术。汽车轴类件批量大、形状复杂、质量要求高,实现其楔横轧的近净成形,必须解决密集窄台阶成形、大断面收缩率成形和成形控性等技术难题。
项目组在国家自然科学基金重点项目、国家科技支撑计划项目等的支持下,十多年来产学研结合,在汽车轴类件楔横轧精确成形理论、关键技术、设备及自动化生产等方面取得了重大突破,与传统工艺比节省材料20%~30%,实现了汽车轴类件高效低耗近净成形。
应用上述创新成果,在全国建成楔横轧汽车轴类件生产线80多条,年产2100多万件。我国80%的商用汽车轴类件已采用楔横轧技术成形,并出口美国福特等公司。项目累计生产汽车轴类件1.4亿件,产值70亿元,节材21万吨。
同行专家鉴定为:“该项目总体技术达到国际先进水平,其中在楔横轧窄台阶精确成形机理,楔横轧一次楔大断面收缩率成形理论与轧制技术、高性能楔横轧机及自动化生产技术等方面处于国际领先地位。” 项目共获国家授权发明专利6项,实用新型专利9项,形成行业标准2项,发表专著2部,论文86篇。近三年实现直接销售收入22.38亿元,新增利润1.64亿元,新增税收1.05亿元,经济效益和社会效益显著。
通过本项目的创新,使我国汽车轴类件生产技术摆脱了低效高耗的落后状态,跃居国际先进行列。与原切削和锻造工艺相比,生产效率提高2~20倍,节材20%~30%,年节省优质钢材3万吨,价值1.3亿元。改善了劳动环境,为汽车轴类件成品企业节省了大量机加工设备、机加工工时及相关费用。
(1)节材效果显著。与锻造相比,平均节材20%,材料利用率由50%提高到60%。与切削比,平均节材30%,材料利用率由40%提高到60%。项目累计生产1.4亿件,节材21万吨。
(2)产品质量好。用楔横轧工艺成形,金属纤维流线连续,晶粒细化,热处理合格率高,产品综合机械性能提高30%以上。
(3)节省用户后续加工费用。楔横轧汽车轴类件精度高,机加工工时缩短,减少了用户设备投资,可为下游企业节省15%机加工辅材、刀具及加工工时费用。
(4)楔横轧汽车轴类件噪音低,自动化程度高,改善了劳动环境,减少了锻造噪音和机加工油烟污染。
主要技术创新点:
十多年来,项目组在国家自然科学基金重点项目《零件精确轧制成形机理与多学科仿真》、国家科技支撑计划项目《大型轴类件楔横轧近净成形工艺与装备研究》、国家科技成果重点推广计划项目支持下,产学研相结合,在汽车轴类件楔横轧精确成形上开展了系统深入的研究,在成形理论、关键技术、设备及自动化生产技术等方面取得了突破性进展,实现了汽车轴类件的高效低耗近净成形。
(1)建立了楔横轧窄台阶精确成形理论,实现了具有密集窄台阶特征轴类件的精确成形。
(2)揭示楔横轧大断面收缩率成形机理,突破楔横轧断面收缩率成形极限,实现了具有大断面收缩率特征轴类件的精确成形。
(3)建立了楔横轧多学科模拟仿真模型,揭示了楔横轧成形机理与微观组织演变规律,实现了楔横轧轴类件的成形控性。
(4)研制出具有自主知识产权的高性能楔横轧机,实现了从上料、加热、进料、轧制、出料生产线自动化。
