The invention provides an intelligent gear shaft forging and rolling process. The intelligent gear shaft forging and rolling process includes the following steps of S1, blank manufacturing; S2, shankforward extrusion; S3, pre-upsetting; S4, small tooth extrusion; S5, large tooth extrusion; and S6, detection and verification. Images of finally-obtained gear shafts are correspondingly shot throughvisible light cameras, the multiple images are subjected to stereoscopic imaging in corresponding processors, then corresponding data are compared with model data in a DEFORM-3D computing platform, meanwhile, the DEFORM-3D computing platform controls corresponding first rotating structures to rotate, irregular parts are cut to a certain degree through first cutting mechanisms, in the longitudinaldirection, the first cutting mechanisms are driven by second rotating mechanisms to carry out cutting, and after ultrasonic flaw detection and mechanical performance testing, finally finished productsare put in storage. By means of the process, the machined gear shafts are comparatively detected correspondingly, then the production precision of the gear shafts is improved, and meanwhile more production materials of the gear shafts are saved.
