The invention relates to the technical field of plasma steel plate cutting feeding, and particularly relates to a plasma steel plate cutting guiding feeding device. The plasma steel plate cutting guiding feeding device comprises a placing mechanism, a supporting mechanism, a pushing mechanism, a limiting mechanism, a sliding mechanism and a pressure reducing mechanism. Through installation of thesupporting mechanism, the placing mechanism can slide and place steel plates conveniently, the steel plates are placed in a stacked mode through the placing mechanism, the occupied space is reduced, the steel plates can be fed conveniently, and the production efficiency is improved. The steel plate on the topmost layer can be pushed and fed conveniently under the action of the pushing mechanism, meanwhile, the steel plates can be fed smoothly in a labor-saving mode under the action of the sliding mechanism, and the feeding efficiency is improved. The placing mechanism can be limited conveniently under the action of the limiting mechanism, so that the steel plates can be stacked conveniently, and subsequent feeding is facilitated. The placing mechanism and the supporting mechanism are protected under the action of the pressure reducing mechanism.
