Bright aluminum alloy soldering wire rolling device

The utility model discloses a bright aluminum alloy soldering wire rolling device which comprises an unwinder, a front straightening device, a rolling mechanism, a rear straightening device and a winder. The unwinder is located in front of the front straightening device which is provided with a plurality of cylindrical straightening cylinders arranged transversely in a staggered mode, and soldering wires penetrate through the centers of the straightening cylinders and then enter the rolling mechanism; the rolling mechanism comprises horizontal double rolling barrels and longitudinal double rolling barrels perpendicular to the horizontal double rolling barrels; semi-arc rolling grooves are formed in the positions, in contact with the soldering wires, of the middle portions of the rolling barrels, the radiuses of the rolling grooves are gradually reduced in the moving direction of the soldering wires, and the rolling grooves of the horizontal double rolling barrels and the rolling grooves of the longitudinal double rolling barrels are concentric; the rear straightening device is also provided with a plurality of cylindrical straightening cylinders arranged transversely in a staggered mode, the rear straightening device is located behind the rolling mechanism, and the winder is located behind the rear straightening device. The bright aluminum alloy soldering wire rolling device can achieve the technical purpose of stretching the soldering wires in a rolling mode.
