The invention discloses flexible shaft toughening equipment and flexible shaft toughening forming method for bent glass. The equipment comprises a transition section, a forming section and a toughening section, the transition section comprises a plurality of tensioned flexible cables and transition roller ways installed on the flexible cables, the flexible cables and the transition roller ways form a forming net, and in the process that heated glass passes through the forming net, the glass is gradually formed; the forming section is provided with a plurality of upper forming arc plates and aplurality of lower forming arc plates, the upper forming arc plates and the lower forming arc plates are respectively provided with forming roller ways or a plurality of rotatable forming roller wheels, and a forming channel is formed between the forming roller way or the plurality of forming roller wheels on the upper forming arc plates and the forming roller way or the plurality of forming roller wheels on the lower forming arc plates; and the equipment can also comprise a shape stabilizing section to correct the shape of the curved glass. By utilizing the equipment provided by the invention, the curved glass meeting the requirements is obtained after the glass is subjected to a gradual change stage, a forming stage and a shape stabilizing stage, and toughening is performed, so that theprecision and quality of the curved glass are improved.
