A forming equipment of a steel pipe pillar is provided to improve productivity by forming a steel pipe pillar through a single simple process of performing bending and welding operations, improve quality of the steel pipe pillar by forming the steel pipe pillar in a way that the steel pipe pillar is tapered to a shape similar to a real circle, and reduce manufacturing cost and improve workability and operation efficiency by simplifying structure of the forming equipment. A forming equipment of a steel pipe pillar comprises: a body(10) which is longitudinally formed in the length direction, and which forms a base and an external appearance of the steel pipe pillar forming equipment; a plurality pair of bending units(20) which are installed at both sides on a bottom surface of the body in a predetermined distance to bend a steel sheet workpiece that is longitudinally formed in the length direction; a plurality of pressurizing units(30) which is installed under the ceiling of the body in a predetermined distance, and which press end portions of the steel sheet workpiece that has been rolled up in a circle shape to form the steel sheet workpiece with a real circle shape; a mold dies(40) which is installed between the bending units and the pressurizing units, and which forms the steel sheet workpiece into a real circle by winding the steel sheet workpiece on an outer peripheral surface of the mold dies while the mold dies is vertically lifted and lowered; and at least one welding unit(50) which is installed at one side of the body to weld portions of the steel sheet workpiece that have been bent such that the bent portions come into contact with each other while the welding unit moves side to side.
