Automatic production line design for surface induction-hardening of high-speed railway axles
摘要
Abstract
Surface induction-hardening imparts a material structure to high-speed railway axles that is hard on the outside and tough on the inside.The hardened surface layer can mitigate fretting fatigue in the axles,enhance their resistance to external damage,and comprehensively improve the service safety level throughout the entire lifecycle.Meanwhile,surface residual compressive stress can slow or inhibit crack propagation,increase the axle's load-bearing capacity,and enable lightweight axle design.Axle service safety depends not only on the lifecycle service adaptability design of surface induction-hardening processes determined by axle material,geometric dimensions,and service conditions,but also on automated production equipment with precisely controllable process parameters.To reduce labor input,improve the production efficiency,quenching quality stability,and controllability of axle surface induction-hardening,this study develops two automated production lines for axle surface induction-hardening.It elaborates on the design methods and workflow of these automated production lines,compares the advantages and disadvantages of the two production lines,and provides an efficient and intelligent technical solution for the domestic production of induction-hardened railway axles in China.关键词
