The invention discloses a push-bending forming method and device for a thin-wall pipe with the adjustable bending radius. According to the method, a fixing rod is inserted into a circular through hole in a movable push table, and then the surface, located on one side of a supporting frame, of the fixing rod is sleeved with the thin-wall pipe; after sleeving is completed, a pipe bending mold is installed at the end of the fixing rod; the pushing mechanism is started after the outer side end of the fixing rod is fixed, the thin-wall pipe on the surface of the fixing rod is pushed to the heating position to be heated, and the heating coil is moved away after heating is completed; and the movable pushing table is used for pushing the heated thin-wall pipe to the bending position, the sliding table positioning mechanism is started, the rolling wheels are controlled to move back and forth according to the moving route when the movable pushing table pushes the heated thin-wall pipe, and the thin-wall pipe is pushed
