The invention discloses a warm-cold composite forging production process for a hollow shaft sleeve of a transmission shaft of an SUV (sports utility vehicle). The warm-cold composite forging production process comprises the following steps of blanking, warm forging, annealing, finishing and drawing-out, finish machining and quenching. By the adoption of the technical scheme, the transmission shaft hollow shaft sleeve is high in internal structure density, good in product mechanical performance and stable in quality, meanwhile, production cost is reduced, production efficiency is improved, and product precision is high.
