Automatic feeding type cold header

The invention relates to the technical field of cold headers, in particular to an automatic feeding type cold header. The automatic feeding type cold header comprises a cold header body, a motor is installed on the rear end face, close to the right end, of a feeding supporting plate, an output shaft is coaxially connected with a traction roller, a fixing plate is arranged in a clamping groove, a roller is arranged in the middle of the fixing plate, a fixed clamping plate is installed on the portion, close to the rear end face, in the feeding supporting plate, a movable clamping plate is installed on the portion, close to the front end face, in the feeding supporting plate, a second pulley is arranged on the rear end face of the movable clamping plate and corresponds to a first pulley, and a threaded rod is arranged in the middle of the front end face of the movable clamping plate. According to the automatic feeding type cold header, the motor is matched with the traction roller, bars or wires needing to be machined are preliminarily dragged, the fixing plate is matched with the roller, traction use is better carried out, the movable clamping plate is matched with the threaded rod, the distance between the movable clamping plate and the fixed clamping plate is convenient to adjust, the automatic feeding type cold header is suitable for clamping the bars or the wires with different thicknesses, and feeding and use are more stable.
