Abstract
The utility model discloses a stretching and cutting mechanism for an armature wire. The stretching and cutting mechanism for the armature wire comprises an emptying device, a pulling wheel set, a straightening device, a cutting device and a power device. The emptying device, the pulling wheel set, the straightening device, the cutting device are connected with each other one by one, the pulling wheel set comprises at least two pulling wheels, wire rods are wound on the pulling wheels in sequence, and the power device supplies power for the pulling wheel set. Within the pulling wheel set, the linear velocity of a back pulling wheel is bigger than the linear velocity of a front pulling wheel in the direction of wire rod delivery. Wire rods pass the pulling wheel with smaller linear velocity first, and then pass the pulling wheel with bigger linear velocity.
