Abstract

The invention discloses a stretch forming machine for a direct-current armature lap winding, comprising a base, a limiting element fixedly arranged on the base and used for limiting one side edge of a coil, a pull rod rotatably arranged on the base, and a crimping element rotatably arranged on the pull rod and used for pulling the other side edge of the coil, wherein a limiting locking groove for locking one side edge of the coil is formed on the limiting element and two guide rails for guiding the stretching direction of a coil frame are also arranged on the limiting element; a positioning locking groove for locking the other side edge of the coil is formed on the crimping element; and the crimping element is driven by the pull rod to slide on the outer peripheral wall of the crimping element so that the distance between the positioning locking groove of the crimping element and the limiting locking groove of the limiting element is changed. A lap winding coil manufactured by the stretch forming machine is good in consistency; and the productivity is high; and therefore, the reliability of finished product motors can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of coil forming, and in particular relates to a DC armature stacked winding stretch forming machine. Background technique [0002] For DC armature stacked windings, round insulated wires are used only in motors with small capacity and multi-turn windings around the city, and flat wires are used as single-turn windings when the capacity is slightly larger. Since the stacked windings of the DC armature are connected to the commutator, the armature windings are made of copper wires. [0003] Stacked winding is a commonly used DC armature stacked winding, such as figure 1 As shown, it is also called parallel winding, and the number of parallel branches (single stack) as many as the number of poles can be obtained, so a larger current can be obtained. [0004] Traditionally, stacked windings are mostly manufactured using complex molds, but this manufacturing method is time-consuming and laborious, and it is dif...
