The invention relates to the technical field of electric power and machines, in particular to an improved busbar bending die. The improved busbar bending die is provided with a lower fixing base, an upper fixing base, a forming die piece, an ejector rod, a lower fixing component, an upper fixing component and a pin shaft. The improved busbar bending die is characterized by further comprising a force bearing component; in the improved busbar bending die, through cooperation of a protruding component of the forming die piece and a V-shaped groove, the regular and accurate bending angle is formed, and adjacent bending angles in the near distances are achieved; and through the improvement of the upper fixing base, the weight is reduced. Compared with the prior art, the improved busbar bendingdie mainly has the following beneficial technical effects that the structure is simpler, the weight is smaller, the forming angle is more accurate, and the bending angles can be close to one another.
