采用楔横轧工艺生产凸轮轴毛坯 ,节材率达 2 0 %～ 4 0 % ,具有工艺合理、技术先进、质量可靠等优点。采用该工艺现已生产 4～ 6缸凸轮轴 2 0 0多万根 ,并建成专业化生产工厂。它是在理论与实践上解决了窄台阶轧齐曲线问题、根圆轴颈拉细与折叠、高精度轧制等一系列难题后取得的 ,具有显著的经济效益和社会效益
Cross wedge rolling process using the production of camshaft rough, section rate of 20% ~ 40%, with reasonable technology, advanced technology, quality, reliability and so on. The process is now used to produce 4 to 6 cylinder camshafts 200 million, and built a specialized production plant. It is obtained in theory and practice after solving a series of problems such as narrow-step rolling alignment curve, root round neck thinning and folding, high-precision rolling, and the like, and has remarkable economic and social benefits
