The utility model discloses a kind of pipe column inner and outer spline integrated forming tool and equipment, wherein, pipe column inner and outer spline integrated forming tool includes press mould and piece moving mechanism, press mould includes the first die holder and the second die holder that can be mutually close or far away, a pair of outer spline extrusion tooth mould and inner spline extrusion tooth mould and multiple pairs of pipe reducing male die and pipe reducing female die are arranged on the first die holder and the second die holder. First, the diameter of the two ends of pipe column is reduced by multiple pairs of pipe reducing male die and pipe reducing female die in multiple times, so that the shrinkage of each diameter reduction section is controlled within reasonable range, effectively avoid the problem that extrusion fails due to excessive extrusion force causing pipe column to bend, thereby greatly improving the yield rate, reduce production cost, and, the pipe column inner and outer spline integrated forming tool is added by piece moving mechanism, the transfer of feeding process, pipe reducing process, extrusion tooth process and discharging process can be realized, so that the processing of pipe column can be fully automated.
