The invention discloses a sheet stamping and forming production line. The sheet stamping and forming production line comprises a stamping device, a leveling machine and a feeding transmitting roller positioned between the stamping device and the leveling machine, wherein at least one pair of limiting rollers which abut against the two sides of a belt-shaped rolled material is arranged on the feeding transmitting roller; each pair of limiting rollers is inclined and is in the shape of V; a plurality of layers of lower ring sleeves which are coaxial with the feeding transmitting roller and are different in diameter detachably sleeve the feeding transmitting roller; and the outermost layer of the lower ring sleeves is in contact with the bottom of the rolled material to support the rolled material, so that the rolled materials of different widths can be limited in a width direction of the rolled materials, and therefore, precise transmission of the rolled materials is realized.
