Description

[Detailed Description of the Invention] Technical Field The present invention relates to an electric wire leveler that straightens and straightens a square cross-section electric wire as a pre-process when winding and forming a field coil for a rotating machine, for example.

Conventional technology In the past, when winding and forming motor status coils using rectangular cross-section electric wires, it was necessary to use a leveler to remove distortion and make the wires straight as a pre-process. According to the leveler, there were the following drawbacks. This is the first
Referring to the drawings and FIG. 2, 1 is a drum around which an electric wire 2 having a square cross section is wound, and 3 is a known leveler. In the leveler 3, a plurality of rollers 5 are installed horizontally on a mounting frame 4, and the electric wire 2 passes between them while being bent up and down in a zigzag manner.At this time, distortion is removed. The electric wire 2 pulled out from the last roller 5a is passed through the winding machine 6.
As the winding frame 7 rotates, it is wound around the winding frame 7, which is approximately rectangular and has pointed ends, and is formed into a stator coil. 8 is a winding shaft.

Therefore, in the conventional electric wire leveler, the mounting frame 4 of the roller 5 is fixed to the support stand 9, and on the other hand, when the stator coil winding frame 7 of the winding machine 6 rotates, the electric wire 2 is wound up on the winding frame 7 while reciprocating in the axial direction of the winding frame 7 between the solid line and the chain line in FIG. However, when forming the stator coil, the winding portion 7 of the winding frame 7 is
If the electric wire 2 drawn out in the direction a is not drawn out straight but in a bent state as shown in the figure, there is a problem that the wire 2 will be deformed again after being wound and formed into a stator coil.

Purpose of the invention The present invention improves the above-mentioned conventional drawbacks, and aims to provide a wire leveler that does not deform again after straightening the wire.

Summary of the invention The electric wire leveler according to the invention removes the strain by applying the rectangular cross-section electric wire drawn out from the winding drum to the leveler, and then unwinds the electric wire coming out of the leveler while rotating the winding frame of the winding machine. In an electric wire leveler that winds a coil around a winding frame while reciprocating in an axial direction, a roller mounting frame of the leveler is supported by a bearing on a support base so as to be rotatable along a vertical axis. The present invention is characterized by a configuration in which the roller mounting frame is horizontally rotatable to follow the reciprocating movement of the wire winding position of the winding frame in the axial direction.

Embodiment An embodiment of the present invention will be described below with reference to FIG. In addition, in the figure, the same reference numerals are used to describe the same components as in the prior art.

In the electric wire leveler 3 of the present invention shown in FIG. 3, reference numeral 10 denotes a rotation support base that supports the roller mounting frame 4. The rotation support base 10 is supported by a thrust bearing 11 on a base 12, and rotates along a vertical axis. It is supported freely.

Therefore, according to the above configuration, as can be seen from FIG. 1 which shows a conventional example, the electric wire 3 pulled out from the outlet 3a of the leveler 3 reciprocates in the axial direction of the winding frame 7 between the solid line and the chain line. When the electric wire 2 is wound while moving, the rotary support base 10 according to the present invention is horizontally rotatably supported by the thrust bearing 11 as shown in FIG. Therefore, the electric wire 2 that is pulled out from the wire outlet 3a of the leveler 3 toward the winding part 7a of the winding frame 7 is always pulled out in a straight state.

As mentioned above, the roller mounting frame 4 is mounted on the horizontal support shaft 13 and supported by the rotation support stand 10, and the mounting frame 4 is mounted on the horizontal support shaft 13 as a fulcrum.
The front and rear ends of are provided to move up and down like a seesaw, and as the winding frame 7 rotates and the winding position of the electric wire 2 pulled out from the leveler 3 moves up and down, the roller mounting frame 4 moves up and down. It is configured to be able to swing.

Effects of the Invention As described above, according to the wire leveler of the present invention, when the wire pulled out from the leveler is wound onto the take-up frame while reciprocating along the axial direction of the take-up frame, the leveler The roller mounting frame also follows this movement and swings along the vertical axis.
The wire is always pulled out horizontally from the outlet of the leveler in a straight state, and therefore the wire wound on the winding frame does not suffer from the distortion seen in conventional examples that do not have this type of device. This has the excellent effect of eliminating the problem of deformation again after being wound and formed into a stator coil etc. as in the conventional case.
