Embodiment Construction

[0007] The present invention is a driving shaft processing technology, comprising the following steps: step 1, forging, select low-carbon alloy steel material, reserve margin according to the drawing requirements, forging and forming; step 2, normalizing, normalizing the forged and formed product Fire treatment, in the process of normalizing, high temperature normalizing at 905°C-915°C is used to refine the bad structure, eliminate the band structure and Widmansite formed by forging; step 3, rough turning, remove a large amount of allowance, and the Preliminary forming is carried out. During the rough turning process, the unilateral reserved machining allowance of the product is 0.75-1mm, and the roughness is Ra6.3; step 4, finish turning, the outer circle and end surface are formed according to the technical requirements, and the finish turning process The surface roughness of the product formed by the medium precision car is Ra1.6; step five, drill deep holes, and drill the d...

Abstract

The invention discloses a driving shaft processing technique. The driving shaft processing technique includes the steps of forging, normalizing, rough turning, finish turning, deep-hole drilling, hobbing, oil-hole drilling, carburizing, induction hardening, external grinding and completion of finished products. Surface hardness and core tenacity of driving shafts produced by the driving shaft processing technique can be improved, and deformation of the driving shafts can be reduced.

Description

technical field [0001] The invention relates to a driving shaft processing technology. Background technique [0002] Automobile driving shaft is one of the important parts in automobile transmission mechanism, which requires high surface hardness and core toughness. Carburizing quenching or induction hardening processes are usually used now. Although carburizing and quenching can ensure high surface hardness and core hardness, it is difficult to control the deformation during quenching; although induction quenching can effectively control deformation, the surface hardness and wear resistance cannot meet the requirements. Therefore, there is a need for a processing technology of the drive shaft, so that the processed drive shaft has higher surface hardness and core toughness. Contents of the invention [0003] The invention provides a driving shaft processing technology, the product made by the technology can not only improve the surface hardness and core toughness of the...
