Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 5 are please referred to Fig.1, the utility model provides a kind of technical solution：A kind of flat device of round wires, including fixed frame 1,
The top of guide wheel 2, the first fabric wheel 3 and the second fabric wheel 4,1 inside of the fixed frame is installed with dead axle 7, the dead axle 7
Outer wall is rotatably connected to guide wheel 2, and the bottom side of 1 inside of the fixed frame is rotatablely equipped with first rotating shaft 8, the first rotating shaft
8 outer walls are rotatably connected to the first fabric wheel 3, and side of the bottom far from first rotating shaft 8 of 1 inside of the fixed frame is installed with
One end of jackscrew plate 10,10 inside of the jackscrew plate is rotatably connected to the second shaft 9,9 outer wall of the second shaft rotation connection
There are the second fabric wheel 4,2 outer wall of the guide wheel to be wound with round wire 5, the round wire 5 passes through the first fabric wheel 3 and the second crimping
Flat conductor 11 is formd between wheel 4.
5 outer wall of the round wire is uniformly bonded with insulating point gummed paper layer 12, the round wire 5 and insulating point gummed paper layer 12 it
Between form tungued-and-grooved face, and 11 outer wall of flat conductor is uniformly bonded with insulating point gummed paper layer 12, the flat conductor 11 with
Surfacing between insulating point gummed paper layer 12 after round wire 5 is squeezed into flat conductor 11 in this way, ensure that coil surface is flat
Whole, 5 diameter dimension of the round wire is 2.5 millimeters, and first gap 13, the first gap are formd between the round wire 5
13 cross-sectional dimensions are 1.3413 square millimeters, and Second gap 14 is formd between the flat conductor 11, and described second is empty
14 cross-sectional dimension of gap is 0.6022 square millimeter, after round wire 5 is squeezed into flat conductor 11 in this way, improves coil filling
Coefficient, 2 outer wall of the guide wheel are uniformly provided with groove 6, and the position of round wire 5 is limited by the way that groove 6 is added, prevents round wire 5
It falls off from guide wheel 2, first fabric wheel 3 is matched with the second fabric wheel 4, passes through the first fabric wheel 3 and the second fabric wheel 4
Flat conductor 11 can be squeezed by round wire 5 by matching.
