Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for straightening a general wire such as a wire or a coil terminal wire from a bent state to a straight state.

[Conventional technology]

Previously, the wire had to be pulled and straightened by hand. There were also cases in which the nails were pressed and straightened to prevent them from bending. (For example, Publication of Utility Model Publication No. 15-19371, etc.) [Problems to be Solved by the Invention] However, in the latter conventional method mentioned above, when the coil terminal wire is long, it bends from the base of the coil and becomes long and undulating. There may be cases. In this case, it is impossible to clamp all of the coil terminal wires, and if you try to clamp them forcibly, there is a problem that the coil terminal wires will be damaged.

Therefore, an object of the present invention is to easily straighten the terminal wire of the coil.

[Means to solve the problem]

Therefore, the following configuration is adopted as the device of the present invention.

In a wire straightening device in which the end portion of the wire is distorted from its root portion 3b, a fixing shaping means 8 packed in multiple layers at a predetermined interval, and a wire provided at the outer peripheral end of the fixing shaping means It consists of a straightening stabilizing plate 9 and a plurality of shaping arrows whose arrow ends are separated into bifurcated shapes. moving means 4a, 4b for inserting the moving shaping arrows between the fixing shaping means so as to sandwich the wire; The moving straightening arrow is a device for straightening a wire, characterized in that the wire is straightened into a substantially straight line by sequentially straightening the wire from the root of the wire.

〔Example〕

FIG. 1 shows a state in which a coil 2 wound in an assembled body using a coil according to the present invention has been inserted into a stator 1. This wound coil 2
has lead wires 3 at the beginning and end of the winding. The amount of distortion and deformation of this lead wire 3 and its tip portion 3a is greater than that of the root portion 3b.

To explain the device of the present invention from FIG. 2, 4a,
Reference numeral 4b denotes a holder for the moving shaping arrow packed in multiple layers at predetermined intervals, 5 the moving shaping arrow, 7 a spacer, and 6 a tightening bolt for the moving shaping arrow.

Now, the fixing shaping arrow 8 is moved coaxially with the coil 2 wound or inserted into the stator 1 to a position where it contacts the coil 2 by a known driving device (not shown). Reference numerals 11 and 12 denote fixed shaping arrow holding plates which are packed in multiple layers at a predetermined interval similar to the predetermined interval of the moving shaping arrow 5, 10 is a spacer, and 9 is a lead wire straightening guide plate. .

After the fixed shaping arrow 8 moves, the movable shaping arrow holder 4a moves forward toward the fixed shaping arrow 8 by a known drive device (not shown).

The reason why the holder 4a moves before the holder 4b is because the lead wire root portion 3b has less distortion and deformation than the tip portion 3a and can be reliably picked up by the moving shaping arrow 5a. In order to make it easier to pick up the lead wire with the shaping arrow, steps are provided in the order of 5a, 5b, and 5c.

When the holder 4a moves and becomes combed with the fixed shaping arrow 8, the center part of the lead wire 3 is connected to the root part 3b.
The structure is such that even if the upper holder 4b moves due to distortion or deformation, the lead wire tip 3a can be reliably picked up.

Although the lead wire 3 is straightened to the specified position by the above operation, the position of the base portion 3b of the coil is bent because the lead wire 3 can be held at the specified position even if the shaping arrow holders 4a, 4b retreat. In order to set the shape, as shown in FIG.
is made larger in the outer circumferential direction than the fixed shaping arrow 8 and the guide plate 9, as shown in FIG.

The guide plate 9 is used to correct the distortion of the lead wire 3 which is straightened with the fixed shaping arrow 8 and the movable shaping arrow 5 in a combed state.

〔Effect of the invention〕

As described above, the wire rod can be straightened from the vicinity of its root, and even if it is bent in various directions, it can be easily straightened by an automatic machine or the like.
