Abstract

PURPOSE:To simplify machining and reduce machining time for coping with modification of coil specifications by using a plurality of rod-shaped coil core where line grooves for positioning a wire are provided at an outer periphery are used between a pair of flanges by cutting a molded object. CONSTITUTION:Four cores 10 where a line groove 11 for positioning a wire which is coil-wound on the outer periphery of a round rod is machined are positioned between a pair of flanges 13 and 13 for constituting a roll frame and a coil roll frame is constituted by tightening with a stud 14 and a nut 15. A wire 20 is coil-wound along the line groove 11 of the core 10 of the coil former for forming a first coil layer and is wound in multiple layers successively along a recessed groove between the wires of the layers where the wires were wound already starting from the second layer for completing the coil, thus simplifying machining of the coil former and reducing the machining time, reducing the quantity of the coil formers since no coil formers need to be prepared every time the coil specifications change, and hence obtaining the title coil former which is also inexpensive.

かり、生産効率が悪くなり、コストが非常に高くなる。In the conventional bobbin 2, a non-metallic material such as engineering plastic is processed into a rectangular plate, and then a groove 5 is provided at each corner for positioning the wire to be wound. However, when processing the parallelism of the plate, it is difficult to process with high accuracy because it is thermally affected by the wide material and causes warpage. For this reason, it takes a lot of time to accurately process the groove 5 of each corner portion in parallel, the production efficiency is deteriorated, and the cost becomes very high.

The winding core 10 is a molded product in which a groove 11 for positioning a coil winding wire is formed on the outer circumference of a round bar made of a non-metallic material such as engineering plastic, and a through hole is provided in the center thereof. . Four cores 10 are used, and each core 10 is provided between a pair of flanges 13 and 13 made of a material such as aluminum.
Assembling coil winding forms are constructed by arranging the winding frames at upper and lower two positions with a space therebetween, inserting the studs 14 through the through holes of the respective winding cores 10 and tightening them with nuts 15 so as to be detachable. At this time, the core 10 is used by cutting the molded product according to the axial dimension of the coil. Flange 13
Has a through hole 16 for the winding shaft at the center thereof, and four holes 17 through which the stud 14 penetrates at the position where the winding core 10 is mounted. A notch 18 is formed through which an adhesive tape for fixing the wire passes.

プをコイルの外周に巻いて固着しコイルを完成させる。In the coil winding die thus constructed, as shown in FIG. 2, the through hole 16 is attached to the winding shaft 19 and the wire 20 is aligned along the groove 11 of the winding core 10 located at the corner. In this state, the coil is wound to form the first layer of the coil, and from the second layer, the layers are aligned and wound along the grooves between the wires of the already wound layer, and the layers are successively wound into multiple layers for coil winding. An adhesive tape (not shown) is wound around the outer periphery of the coil from the cutout portion 18 of the flange 13 and fixed to complete the coil.

ぐれたコイル巻型が得られる。。By doing this. The groove 11 for positioning the wire 20 is formed in a rod-shaped molded product. When the wire diameter is the same and the axial dimension is different, this molded product is cut and used. When the axial direction is the same and the short side dimension and the long side dimension are different, it is only necessary to change the position of the hole 17 of the flange 13. Therefore, the processing of coil winding dies is simplified, the processing time is shortened, and it is not necessary to prepare winding dies every time the coil specifications change, so the number of winding dies can be reduced and the cost is excellent. A coil winding form is obtained. .
