| description | The utility model discloses a one-step forming die for a gear shaft, wherein a lower die fixing sleeve is arranged at the lower part of a die frame; a concave die pressing ring is internally provided with a gear forming concave die and a square forming concave die in sequence from top to bottom and is arranged in the lower die fixing sleeve; a convex die is arranged at the upper part of the die frame by a fixing nut, a bush and a convex die fixing sleeve and is coaxial with the gear forming concave die; and an ejector rod used for demoulding of a processed workpiece is arranged at the center of the bottom of the die frame by an adjusting nut. In the utility model, the structures of the convex die and the concave die are optimized, the strength of the convex die and the concave die are improved, and the service life of the die is prolonged; a special die structure is adopted, so that a power transfer square and a tooth form are formed by one step, the requirement on the quality of workpieces is ensured, the pr |
