With market demands, customer demand for electric motors is increasing. Motor performance is strongly related to the stator coils, and the process of the stator coils includes the winding of the coils. In the coil winding process, copper wires are regularly and orderly arranged on a winding former. Meanwhile, the stator coil also has requirements on the overall dimension, the winding quality is not in accordance with the requirements, the wire embedding quality and the wire embedding difficulty can be influenced, the coil length at the end part can be caused to be uneven, the appearance is attractive, the assembly difficulty can be caused, the creepage distance can be influenced, the motor performance can be directly influenced, a multi-purpose copper wire is used in the manufacturing process, and the manufacturing cost of the motor is directly increased.

However, the template of the multifunctional motor coil winding mold with the publication of CN205986556U has no hollow structure, so that the upper plate and the lower plate can not be directly separated when the upper plate and the lower plate are opened and closed, and the coils are inconvenient to be quickly separated, and the winding mold of the motor coil is provided to solve the problems

As shown in fig. 1, the winding former of the motor coil comprises an upper template 1 made of a wood board material, wherein a first bump 3 is only arranged on the right side of the bottom of the upper template 1 in the Y-axis direction of fig. 1, a first wire passing groove 6 is only arranged on the right side of the upper template 1, a lower template 2 made of a wood board material is arranged under the upper template 1, a second bump 4 is arranged on the left side of the top of the lower template 2, and a second wire passing groove 7 is arranged on two sides of the lower template 2.

The bottom of cope match-plate pattern 1 faces the top of lower bolster 2, and when cope match-plate pattern 1 and lower bolster 2 superpose in the Z axial, first protruding 3 pieces can paste and lean on the top at lower bolster 2, and second lug 4 can paste and lean on the bottom at cope match-plate pattern 1, is equipped with interval 8 between first lug 3 and the second lug 4.

In fig. 1-3, only one set of upper and lower templates 1 and 2 is provided, and preferably, a plurality of sets of upper and lower templates 1 and 2 are combined and stacked together. More preferably, a bump is respectively arranged at the upper and lower positions of one template, and the bumps are respectively arranged at two ends of the template. The upper template 1 and the lower template 2 can slide relatively.

The first bump 3 and the second bump 4 are the same in size, the outer sides of the first bump 3 and the second bump 4 are both arc-shaped, and the arc-shaped directions of the two bumps are opposite; so as to ensure the coil standard of the outer surface winding of the first projection 3 and the second projection 4, and in the arc-shaped arrangement, the coil is wound on the arc-shaped to reduce the crease problem when the coil is wound.

A concave part for winding is arranged between the upper template 1 and the lower template 2, namely the maximum width of the first lug 3 and the second lug 4 is smaller than the maximum width of the upper template 1 and the lower template 2. Preferably, the width of the connecting line between the two ends of the arc of the first bump 3 or the second bump 4 is smaller than the width of the two ends of the upper template 1 and the lower template 2, and when winding, the coil is limited by the upper template and the lower template up and down to prevent separation.

As shown in fig. 4, the upper and lower templates 1 and 2 are stacked and fixed to each other by the binding 9, and the upper and lower templates 1 and 2 can slide relatively. Preferably, the binding 9 is a rope belt, the binding 9 is wound between the upper template 1 and the lower template 2, and the loop formed by winding the binding 9 is perpendicular to the sliding direction of the upper template 1 and the lower template 2. The sliding direction of the upper template 1 and the lower template 2 is the Y-axis direction, and the sliding time interval 8 of the upper template 1 and the lower template 2 can be changed at the moment.
