The invention relates to equipment for automatically lifting, continuously feeding, sawing and heating bars. The equipment comprises a loading device, a lifting device, a feeding device, a blanking device and a heating hot punching device, wherein the loading device comprises a loading frame, a loading platform, an ejector rod, a linkage rod, a driving wheel and an ejector cylinder; the lifting device comprises a lifting chain, a chain wheel, a driving chain wheel and a lifting motor; the feeding device comprises a feeding frame, a V-shaped wheel, a compression cylinder, a compression guide wheel and a feeding limit switch; the blanking device comprises a guide mechanism, a saw-cutting mechanism and a material rotating mechanism; and the heating hot punching device comprises a heating groove, a heating furnace, a blanking guide groove and a punch press. A fully-automatic production line of lifting, feeding, blanking and heating hot punching is manufactured and formed on a valve shell, so full-automatic control is realized, production efficiency is improved, energy consumption is saved, workers are protected from directly operating beside the heating furnace, scalding and sunstroke accidents are avoided, labor intensity is reduced, and the automatic level is increased and product quality is improved.
