Arrangement of Heat Treatment Processes

Normalizing treatment is usually arranged first after forging of axle blank to eliminate internal stress in forging, refine grain size and improve cutting performance during machining.Heat treatment processes should be arranged to ensure the mechanical properties and processing accuracy requirements of gear shafts, and improve the workpiece processing performance In the whole process of axle After rough processing, conditioning heating treatment is arranged. In the rough processing stage, after rough turning, drilling and other processes, most of the processing allowance of gear shaft is removed. The cutting force and heat are very large in rough machining process. Under the action of force and heat, the axle produces great internal stress. The internal stress can be eliminated by conditioning treatment instead of aging treatment. At the same time, the required toughness can be obtained.

All the surfaces except the important ones have reached the design size after semi-processing. There is only finishing allowance on the important surfaces. At this time, local quenching treatment is arranged on the teeth to meet the hardness requirements of the design and ensure the wear resistance of these surfaces. The subsequent finishing process can eliminate quenching deformation.
