Steel plate arc-shaped manufacturing device

The utility model relates to the technical field of building construction, in particular to a steel plate arc making device which comprises a bottom plate, a positioning structure is arranged on one side of the upper end face of the bottom plate and comprises two positioning plates arranged in parallel, and a clamping groove is formed between the two positioning plates. One sides of the top ends of the two positioning plates are fixedly connected with limiting plates, clamping grooves are formed in one sides of the connecting positions of the limiting plates and the positioning plates, and the radian of the arc edge is the preset bending degree of the steel plate, so that the specific radian of the arc edge is not limited and is set according to actual operation requirements; the steel plate is bent through external forming equipment, so that arc-shaped steel manufacturing is facilitated, the equipment is easy to operate and low in cost, and the manufacturing efficiency of a small number of arc-shaped steel p
