Special-shaped pipe forming device using dot matrix soft mold

The invention relates to the field of pipe non-cutting forming, in particular to a special-shaped pipe forming device utilizing a dot matrix soft mold. The special-shaped pipe forming device utilizing the dot matrix soft mold comprises an inner section mold and an outer section mold, one of the inner section mold and the outer section mold is the dot matrix soft mold, the other one is a rigid mold, and a forming structure attached to a formed special-shaped pipe is arranged on the rigid mold. The dot matrix soft mold comprises at least two feature areas with different dot matrix structures so as to correspond to different forming areas on the pipe blank. In the forming process, the dot matrix soft mold pushes the pipe blank to be attached to the rigid mold for forming of the pipe blank, and due to the fact that the characteristic areas with different dot matrix structures can conduct distinguished loading and deformation on the pipe blanks needing different deformation degrees, the problems that in the prior
