Steel bar bending machines are convenient for bending and have a fast construction speed. However, most of the existing bending machines can only bend one end of the steel bar and cannot bend both ends of the steel bar in two directions at the same time. The steel bars need to be moved repeatedly, which is laborious and inconvenient to operate. Utility Model Content

[0011] 1. The output end of the first motor drives the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod drives the two sliders to move relative to each other along the horizontal direction of the slider. The relative movement of the two sliders enables the bending operation of the two ends of steel bars of different lengths.
