The utility model provides a combined bracket sliding seat, and aims to overcome the pervasive defects that tube blank feeding is difficult, and core rods are easy to be broken off due to lack of centering mechanism in conventional bracket sliding seats. The combined bracket sliding seat comprises two parts of a tube blank bracket and a core rod bracket; the tube blank bracket is characterized in that a double-side tooth rack is fixedly connected with an upper roller rack; left and right tooth racks are fixedly connected with a lower rolling rack; an air cylinder pushes an upper roller to move through the double-side tooth rack upper roller rack, drives left and right gears to rotate at the same time to enable the left and right tooth racks to move in the opposite directions, and drives a lower roller to move to supports a tube blank or a core rod; the structure of a core rod bracket is similar to that of a tube blank bracket; the difference is that the roller of the tube blank bracket rotates perpendicular to a rolling center line; the roller of the core rod bracket rotates parallel to the rolling center line. The combined bracket sliding seat has the characteristics that the combined bracket sliding seat is compact in structure, good in self centering, easy and reliable in feeding, low in labor intensity, high in production efficiency and good in product quality, and can be widely applied to cold pilger mills.
