Busbar bending die

The invention relates to the field of workpiece bending equipment, in particular to a busbar bending die which comprises a convex die and a concave die, wherein the concave die is provided with a guiding groove; the guiding groove is provided with two guiding surfaces; the two guiding surfaces are used for being in sliding fit with a busbar in a guiding manner and are arranged in parallel at an interval; a concave die forming piece for being matched with the convex die to bend the busbar is assembled between the two guiding surfaces in the moving direction of the convex die in a sliding manner; and the guiding groove is adopted to guide the busbar in the moving direction of the convex die, so that the situation that deformation in the direction perpendicular to the moving direction of theconvex die is avoided during the busbar bending process is ensured, and the moving direction of the convex die is the busbar bending direction. After bending forming is in place, an elastic reset piece is adopted to apply ela
