Problems solved by technology

This production method is suitable for the manufacture of small-sized saddle-shaped coils. For the production of saddle-shaped coils for high-power motors, the efficiency is low, it is not easy to operate, the coil size is not easy to guarantee, and it is easy to damage the insulating layer wrapped on the surface of the copper wire, which reduces the quality of the coil. , the scrap rate increases

Abstract

The present invention relates to a molding device and a molding method of a saddle-shaped coil. The molding device comprises a winding device arranged at a winding machine. The winding device is usedfor winding coils, and the winding device also comprises a primary bending device and a secondary bending device used for positioning and fixing the coil. The device has the advantages of compact andreasonable structure and easy operation. By combining the primary bending device and the secondary bending device, the production of the high-power saddle-shaped coil can be easily realized, and the production efficiency of the coil is improved.

Description

technical field [0001] The invention relates to the technical field of coil forming equipment, in particular to a saddle coil forming device and a forming method thereof. Background technique [0002] The forming method of high-power motor coils is mainly realized by using various expansion machines at present, and the expansion principle adopts the profiling method. This expanding device, because the rotating shaft is fixed, depends on the rotating profiling during expanding, and cannot realize the expanding of the saddle-shaped coil. [0003] For saddle-shaped coils with smaller sizes, at present, after the coil is wound on the winding die, the end molding is completed by artificial end beating or external force extrusion. This production method is suitable for the manufacture of small-sized saddle-shaped coils. For the production of saddle-shaped coils for high-power motors, the efficiency is low, it is not easy to operate, the coil size is not easy to guarantee, and it ...
