しかしながら、上記従来技術には以下のような課題が存在する。
線材に冷却用の長溝及び長穴を有するコイルにおいては、その寸法精度上、上記従来の巻線形成装置により製造することが困難であった。詳細には、例えばドラムに巻かれた線材に予め長溝等を加工したものを用意した場合、ドラム巻線中の線材の伸びまたは後から形成される曲げ部での線材の伸び及び歪み等により、寸法誤差が累積されて、長溝等の所要寸法精度を確保することが困難であった。そこで、線材に長溝等を有するコイルの製造方法は、例えば、(1)線材を所定長さに切断→(2)線材に長溝等を形成するための切削加工→(3)線材をコの字形状にするため線材両端の曲げ加工→(4)コの字形状の線材をロー付の工程で行われていた。そのため、線材の切断及びロー付け等の工数が増加するとともに、作業効率が低下していた。

For this reason, man-hours such as cutting and brazing of wire rods have increased, and work efficiency has been reduced.

A sliding member 38B is provided on the inner side in the width direction of the holding lever 37B, and an actuator 39B (for example, a hydraulic actuator or the like) capable of abutting the tip of the rod 39Ba on the upper surface of the block body 33B is provided on the outer side in the width direction of the holding lever 37B. ) Is provided. The sliding members 38A and 38B are arranged so as not to interfere with the cutting blade 22.

そして、アクチュエータ39Aのロッド39Aa及びアクチュエータ39Bのロッド39Aaが伸長することにより、保持レバー37Aが軸部37Aaまわりに回動して摺動部材38Aが線材8を押しつける力(図5中矢印Cで図示)が働き、また保持レバー37Bが軸部37Baまわりに回動して摺動部材38Bが線材8を押しつける力(図5中矢印Dで図示)が働くようになっている。その結果、線材8の上下面を摺動部材38A,38B及び摺動部材32で狭持するようになっている。これにより、切削刃22の切削力によって線材8に生じた切削反力(垂直分力)を受けつつ、線材8を長手方向に送り出し可能としている。   Then, when the rod 39Aa of the actuator 39A and the rod 39Aa of the actuator 39B extend, the holding lever 37A rotates around the shaft portion 37Aa and the sliding member 38A presses the wire 8 (illustrated by an arrow C in FIG. 5). ), And the holding lever 37B rotates around the shaft portion 37Ba so that the sliding member 38B presses the wire 8 (shown by an arrow D in FIG. 5). As a result, the upper and lower surfaces of the wire 8 are held between the sliding members 38A and 38B and the sliding member 32. Thereby, the wire 8 can be sent out in the longitudinal direction while receiving the cutting reaction force (vertical component force) generated in the wire 8 by the cutting force of the cutting blade 22.

次に、本実施形態の動作及び作用効果を説明する。図6〜図10は、本実施形態の動作を説明するための巻線形成装置1の上面図である。   Next, the operation and effect of this embodiment will be described. 6 to 10 are top views of the winding forming apparatus 1 for explaining the operation of the present embodiment.

まず図6に示すように、ドラム17から送り出した線材8の所定位置(第1の曲げ位置近傍)を曲げ台車11の曲げ装置15が保持する。そして、揺動ビーム3が揺動しつつ曲げ台車11が走行輪4側(図中右下側)に走行することにより、ドラム17から線材8を引き出し、これと同時に、曲げ台車11の線材ガイド14が線材8を押さえつつ曲げ装置15が巻型13のまわりに回動することにより、線材8を折り曲げていく(図7参照)。その後、図8に示すように線材8が引き出され直角まで折り曲がると、保持台車12がベース2側(図中左上側)に走行して保持クランプ16が線材8を保持し、その後、曲げ台車11の曲げ装置15が線材8を離して曲げ台車11がベース2側に走行する(図9参照)。そして、線材8の所定位置(第2の曲げ位置近傍)を曲げ台車11の曲げ装置15が保持し、その後、保持台車12の保持クランプ16が線材8を離して保持台車12が走行輪4側に走行する(図10参照)。このような動作が繰り返されて線材8の所定位置を曲げ加工し、矩形らせん状に巻線形成していく。なお、テーブル10は、上述した曲げ台車11の巻型13の位置に連動して回転し、矩形らせん状に巻線形成したコイル9を的確に積み重ねて載置する。   First, as shown in FIG. 6, the bending device 15 of the bending carriage 11 holds a predetermined position (near the first bending position) of the wire 8 fed from the drum 17. Then, the bending carriage 11 travels to the traveling wheel 4 side (lower right side in the figure) while the swinging beam 3 is swinging, thereby pulling the wire 8 from the drum 17 and at the same time, the wire guide of the bending carriage 11. The bending device 15 rotates around the winding mold 13 while the wire 14 holds the wire 8, thereby bending the wire 8 (see FIG. 7). Thereafter, as shown in FIG. 8, when the wire 8 is pulled out and bent to a right angle, the holding carriage 12 travels to the base 2 side (the upper left side in the figure), the holding clamp 16 holds the wire 8, and then the bending carriage 11, the bending apparatus 15 separates the wire 8, and the bending carriage 11 travels to the base 2 side (see FIG. 9). Then, the bending device 15 of the bending carriage 11 holds the predetermined position (near the second bending position) of the wire 8, and then the holding clamp 16 of the holding carriage 12 releases the wire 8 and the holding carriage 12 moves to the traveling wheel 4 side. (See FIG. 10). Such an operation is repeated to bend a predetermined position of the wire 8 and form a winding in a rectangular spiral shape. The table 10 is rotated in conjunction with the position of the winding die 13 of the bending carriage 11 described above, and the coils 9 wound in a rectangular spiral shape are accurately stacked and placed.

また、上述の動作中において、切削加工装置21の線材保持部24は、線材8を長手方向に送り出し可能に保持している。すなわち、曲げ台車11が走行してドラム17から線材8を引き出す際にも支障をきたすことがない。また線材保持部24は、切削刃23の切削力によって線材8に生じた切削反力を受つつ、線材8を長手方向に送り出し可能に保持する。これにより、例えば線材8を引き出しながら、切削刃22で線材8に長溝(図示せず)又は長穴(図示せず)を切削加工することができるようになり、線材8の曲げ加工と切削加工とを同時に行うことができる。あるいは例えば図8に示すように線材8の曲げ加工が終了したときに(若しくは例えば図7に示すように線材8の曲げ加工中に線材8の送り出しを一旦停止したときに)、切削加工装置21がベース2上を移動しながら切削刃22で線材8に長溝(図示せず)又は長穴(図示せず)を切削加工することができるようになり、ドラム17から送り出した線材8を順次連続的に切削加工することができる。したがって、例えば所定長さの線材に長穴等を切削加工し折り曲げ、それら線材をロー付け等で結合するような製造方法に比べ、工数を低減し、作業効率を向上することができる。また、本実施形態では、線材保持部24で保持する範囲よりも長い寸法の長溝又は長穴を切削加工することができ、これによって切削加工装置21の小型化を図ることもできる。   Further, during the above-described operation, the wire holding unit 24 of the cutting device 21 holds the wire 8 so that the wire 8 can be fed out in the longitudinal direction. That is, there is no problem even when the bending carriage 11 runs and pulls the wire 8 from the drum 17. The wire holding part 24 holds the wire 8 so that it can be sent out in the longitudinal direction while receiving the cutting reaction force generated in the wire 8 by the cutting force of the cutting blade 23. As a result, for example, a long groove (not shown) or a long hole (not shown) can be cut in the wire 8 with the cutting blade 22 while the wire 8 is pulled out. Can be performed simultaneously. Alternatively, for example, when the bending of the wire 8 is completed as shown in FIG. 8 (or when the feeding of the wire 8 is temporarily stopped during the bending of the wire 8 as shown in FIG. 7, for example), the cutting device 21 Can move a long groove (not shown) or a long hole (not shown) in the wire 8 with the cutting blade 22 while moving on the base 2, and the wire 8 delivered from the drum 17 is successively continued. Can be cut. Therefore, for example, man-hours can be reduced and work efficiency can be improved as compared with a manufacturing method in which long holes and the like are cut and bent in a predetermined length of wire, and these wires are joined by brazing or the like. Moreover, in this embodiment, the long groove | channel or long hole of a dimension longer than the range hold | maintained with the wire holding | maintenance part 24 can be cut, and, thereby, size reduction of the cutting apparatus 21 can also be achieved.

なお、上記一実施形態においては、線材8の上面側一方を切削加工する場合を例にとって説明したが、これに限られない。すなわち、例えば線材8の上下面のいずれか一方を切削加工するような構成としてもよい。詳細には、例えば切削加工装置は、線材8の上下面両側にそれぞれ配設した切削刃を備えるとともに、加工する上面及び下面の切り換えに合わせて線材保持部の配置を180度回転させるような構造としてもよい。このような場合も、上記同様の効果を得ることができる。   In the above-described embodiment, the case where one of the upper surfaces of the wire 8 is cut has been described as an example, but the present invention is not limited thereto. That is, for example, it may be configured such that either one of the upper and lower surfaces of the wire 8 is cut. Specifically, for example, the cutting apparatus includes cutting blades disposed on both the upper and lower surfaces of the wire 8 and has a structure in which the arrangement of the wire holding portion is rotated 180 degrees in accordance with switching between the upper surface and the lower surface to be processed. It is good. In such a case, the same effect as described above can be obtained.

また、上記一実施形態においては、線材保持部24は、背面側当接部としての摺動部材32、加工面側当接部としての転動部材38A,38B、及び側面側当接部としての転動部材34A,34Bを備えた構成を例にとって説明したが、これに限られない。変形例を図11及び図12により説明する。 Moreover, in the said one Embodiment, the wire holding | maintenance part 24 is the sliding member 32 as a back surface side contact part, rolling member 38A, 38B as a process surface side contact part, and a side surface side contact part. Although the structure provided with rolling member 34A, 34B was demonstrated as an example, it is not restricted to this . The varying Katachirei be described by FIGS.
