This disclosure relates to the technical field of guardrail fastener processing equipment. One embodiment of this disclosure provides a cold heading forming device for guardrail fasteners, comprising: an equipment base and a forming frame, the forming frame being fixed to the surface of the equipment base, a feeding frame being fixed to the surface of the equipment base, a feeding forming assembly being disposed on the feeding frame and the forming frame, and a stamping and cutting assembly being disposed on the surface of the forming frame and the equipment base. The feeding forming assembly includes a plurality of feeding rollers, all of which are rotatably connected within the feeding frame. Two pairs of conveying rollers are disposed within the feeding frame, one end of each pair of conveying rollers being provided with a transmission gear, and one of the conveying rollers being electrically driven to rotate. A main frame is disposed on the surface of the equipment base. This technical solution solves the technical problem in the prior art where sequential feeding leads to an increased idle time ratio in the device, a limited supply of blanks per unit time, and difficulty in matching the high-speed processing capability of the cold heading forming main unit, thus restricting the overall production line's capacity improvement.
