(3) Mechanical rust remover The mechanical rust remover consists of 2 sets of 90-degree repeated bending rollers. Driven by motor-lifter-lead screw (or pneumatic), the movable bending roller is pushed to extend or retract. Ensure sufficient bending angle between the steel bar and the bending roller to peel off the oxide scale to the maximum. After the oxide skin is peeled off, it falls into the collection tank below for easy cleaning. Fully sealed structure is adopted to prevent dust from escaping in the workshop.

(4) The PC steel rod concave thread forming of the drawing machine adopts the method of matching the drawing speed and the rotation speed of the mold. The mold is well stressed, the mold life is long, and the lead of the steel rod is artificially controlled to ensure the appearance quality of the product. The reducer of the wire drawing machine adopts a medium-hard tooth surface reducer, and there are protective devices at the tank body and the belt. The wire drawing tank is equipped with a shut-down pneumatic pinch roller to prevent the machine from shutting down and disordering the line. The diameter of the reel is 900mm, the maximum drawing speed is 100m/min, the wire drawing machine motor is 90KW, and the rotary die motor is 5.5KW.

(7) There are two tractors. They are respectively placed in front of the quenching heating furnace, and after the tempering and cooling device, they play the role of full-line dragging. The traction machine is composed of three pairs of traction rollers, the lower roller is active and the upper roller is passive. The lower roller device is on the output of a non-standard transmission box with a single shaft input and three output shafts. The upper roller device is in the chute of the upper sliding frame. Keep to ensure the clamping force of the steel bar and ensure the smooth operation of the steel bar. The two tractors adopt micro-tension control technology, which can adjust the tension at any time according to the process needs and keep it between the two tractors. The micro-tension control technology can be used to adjust the tension and maintain at any time according to the process needs, which is automatic control between the two tractors. Under the formation of constant tension to provide guarantee to meet the needs of product quality. The traction roller is composed of two grooves, and the traction roller is arranged on the optical axis through an expansion sleeve to facilitate the replacement of the traction roller. The motor is 11KW, and the reducer is a planetary cycloid reducer.
