This invention proposes a processing technology for hollow stabilizer bars in automobiles. The core of this technology lies in first achieving the final mechanical properties of the tubing through heat treatment, followed by forming and subsequent processing. The process involves online induction heat treatment of the hollow straight tube: sequential induction heating austenitization, quenching (martensitic transformation), and medium-frequency induction tempering (troostitic or sorbitic transformation), followed by water cooling to room temperature and eddy current testing. Then, the hollow straight tube, having achieved its final properties, undergoes end processing (flattening, drilling, welding), followed by cold bending into a three-dimensional shape using a CNC tube bending machine, and immediately undergoes stress-relief annealing to eliminate residual processing stress.

Finally, coating (cleaning, phosphating, electrostatic spraying, baking) forms a protective layer. This process, by prior heat treatment followed by forming, effectively improves the product's heating uniformity, microstructure, and controls residual stress.
