The invention discloses a vulcanization pipe bending device for rubber sleeve cable extrusion and an operation method of the vulcanization pipe bending device. The vulcanization pipe bending device comprises a heat preservation assembly, a heating conduction assembly, a pipe bending assembly, a vulcanization pipe and a PLC control system. The device can effectively improve the bending uniformity and consistency of each point position of the vulcanized pipe, realizes the accurate bending and shaping effects of the vulcanized pipe, and can measure and calculate the vertical displacement of a plurality of point positions relative to the center line according to the bending angle of the vulcanized pipe, thereby meeting the process requirement of the bending deformation quantity of the vulcanized pipe; compared with a bending mode of a traditional rubber sleeve cable vulcanized pipe, the method adopts a mode of combining hot-state bending and cold-state bending, hot-state processing is firstly performed for preliminary forming, the hardness is reduced by utilizing the plasticity of the rubber sleeve cable vulcanized pipe, then cold-state processing is performed for accurate forming, and therefore the problems of cracks and the like of materials are avoided; by means of the operation method of the device, it is guaranteed that deformation of the vulcanized pipe is uniform in the whole bending deformation process, product quality is guaranteed, and the technological requirement for the bending deformation quantity of the vulcanized pipe is met.
