摘　　要：针对高速机车高圆簧外形尺寸大、公差要求严、表面质量及热处理质量要求非常高、疲劳寿命要求高的情况，采用磨削拉光棒料、电热管电炉加热、自制专用靠模卷簧机卷簧以及使用合理浓度的水溶性淬火介质及校正回火、喷丸强化、表面磁粉探伤等措施来生产该产品可防止各种缺陷的产生，提高弹簧质量。Aiming at the practice situation of spring with large shape, tighter tolerances, hight surface and the quality of heat treatment, by choosing the grinding cold drawn bar, heated in the heating tube furnace, using the homemade special spring coiling machine to work and choosing reasonable concentration of water-soluble quenching medium and correction tempering, shot peening, surface magnetic particle inspection, the defects of the spring were prevented and the quality of the product was improved.
