The invention provides a wire end forming die of an armature coil of a direct-current motor, relates to a wire end forming and manufacturing die for an armature coil of a low-voltage and high-current direct-current motor, and mainly solves the problems of excessive forming processes, inconsistent size and low efficiency due to large wire gauge and cross section of an electromagnetic wire of the armature coil of a conventional direct-current motor. The wire end forming die of the armature coil of the direct-current motor comprises an upper die and a lower die, wherein a circular handle is arranged at the upper end part of the upper die, and an oblique angle is formed at the edge of a working surface of the lower end part; an oblique angle surface is formed on an upper working surface of the lower die; and a movable positioning pin and positioning and straightening bearings are arranged on the upper working surface of the lower die. The wire end forming die adopts an air hammer or a friction pressing machine as a power machine, a forging die adopts two rows of bearings to position and straighten the electromagnetic wire, adopts the movable positioning pin for positioning, and utilizes the working surfaces of the upper die and the lower die for performing one-time forming of the electromagnetic wire, so that the wire ends have regular beginning ends and consistent sizes, the processes are reduced, and the production efficiency and the product quality are improved.
