The utility model relates to the technical field of riveting, and provides a riveting column structure and riveting equipment. The riveting column structure comprises a working part and a riveting part, the riveting part is connected to the bottom of the working part, a limiting step is formed at the joint of the working part and the riveting part, the riveting part is of a column body structure, and at least one section of column body, close to the working part, of the riveting part is of a hollow structure. And axial pressure is applied to the riveting part, so that a section of cylinder, close to the working part, of the riveting part is extruded and deformed outwards in the circumferential direction to form an extrusion deformation part. According to the riveting column structure and the riveting equipment, riveting of the riveting column structure and the to-be-riveted workpiece can be achieved in a stamping mode, the to-be-riveted workpiece does not need to be turned over or transferred, riveting can be
