Forging trail hook frame bending and sizing structure

The invention discloses a forging trail hook frame bending and sizing structure. The forging trail hook frame bending and sizing structure comprises a die holder, two sets of rotary templates, connection plates, a slidable template, a small roller, a sizing plate, a guiding block and a side top cylinder; the two sets of rotary templates are horizontally and symmetrically arranged, two connection plates are fixed to the front and rear ends of each rotary templates, the two connection plates of each rotary templates are rotated and connected to the die holder through a rotary shaft, the slidabletemplate is slidably connected to the rotary templates through the small roller, the slidable template, the sizing plate and the guiding block are fixed through screw rods and positioning pins, and the output shaft of the side top cylinder is hinged to the lower end face of the rotary templates. In the bending process of a workpiece, the length change generated in the workpiece bending process iscounteracted with the mov
