３，３の突起４とその没部を嵌め合わせる。 Next, at the third station C, one E iron core 3' is punched out from the band-shaped iron core plate 1 using a punch, and the one E iron core 3' is dropped into the lower die 7 and laminated. At the same time, the projections 4 of the overlapping upper and lower E-iron cores 3', 3' are fitted with their recessed parts, and then at the fourth station D, the other E-iron core 3 is punched out using a punch, and the lower die is formed. The other E-iron core 3' is dropped into the E-iron core 8 and stacked, and at the same time, the protrusion 4 of the upper and lower E-iron cores 3, 3, which overlap each other, is fitted into the recessed part.
この作用における各鉄芯２，３，３′の積層時

うに、ポンチ９の打抜き下降により、Ｉ鉄芯２は
一枚分づつ保持リング１０内を下降するととも
に、上記突起４とその没部の嵌合がなされる。 In this action, the support during stacking of each iron core 2, 3, 3' is performed by the same structure and action,
For the I-iron core 2, this is done by a retaining ring 10 on the lower surface of the lower die 6 shown in FIG. That is, the inner circumference of the retaining ring 10 is narrower by about 3/100 mm over the entire circumference than the hole of the lower die 6, and the I iron core 2 is press-fitted into the retaining ring 10 by the downward force of the punch 9. Retaining ring 1
Support with 0 side pressure. For this reason, as shown in the figure, as the punch 9 is punched downward, the I-iron core 2 is lowered into the retaining ring 10 one by one, and the projection 4 is fitted into the recessed portion thereof.

れる。 On the other hand, when forming the protrusions 4, the punch usually descends deeply for each required number of laminated I-iron cores 2, and punches out without forming the protrusions 4 to form a through hole. Therefore, the fitting of the protrusions 4 of the I-iron core 2 is not performed for each required number of I-iron cores 2, and the I-iron core 2 is fitted with the required number of laminated I-iron cores.
a and descends through the lower die 6 and the retaining ring 10, and when the separation surface passes the lower surface of the retaining ring 10, it falls onto the conveyor 11 perpendicular to the feeding direction of the strip-shaped iron core plate 1, as shown by the chain line. sent to the required location.
その送られた積層鉄芯２ａが半カシメ状態であ
れば、再押し成形されて再カシメされる。 If the sent laminated iron core 2a is in a semi-caulked state, it is re-pressed and re-crimped.

る手段もある。 In addition, to form the above-mentioned through-holes, a through-hole punch is separately provided before the protrusion 4-forming punch, and this punch is applied to each of the required number of sheets to form the through-holes, and the protrusion 4-forming punch is then used to form the through-holes. There is also a method of inserting it into a through hole and causing it to swing in vain.

抜きエリアから外れないように帯状鉄芯１をその
大きい幅の分余裕をもつて送り込むことができ打
抜きのミスなどが生じにくい。 In this manufacturing method, conventionally, as shown in the figure, the strip-shaped iron core plate 1 has a width t wider than the width of the E iron cores 3 and 3', and the other E iron core 3 is also connected to the fourth station D. The final processing is done by punching. That is, the E iron core 3 is attached to the strip iron core plate 1 until the end (it is an integral piece). For this reason,
The belt-shaped iron core 1 can be fed into each station A, B, C, and D with a margin corresponding to its large width so that it does not fall out of the punching area of each punch, and punching errors are less likely to occur.
しかし、同図のごとく、両側に２本の耳５がで

て短く切断したのち回収している。 However, as shown in the figure, two ears 5 are formed on both sides. This ear 5 is a surplus portion and causes an increase in cost. Further, the selvage 5 needs to be disposed of, and conventionally, the selvage 5 is collected by winding it up or cutting it into short pieces with a cutter.
このため、その回収装置が必要であり、その回
収耳５を適宜に廃棄しなければならないなどの問
題がある。 Therefore, a collecting device is required, and there are problems such as the need to dispose of the collecting ear 5 appropriately.

幅と同じ幅ｔのものとすれば、耳５の発生がなく
なるが、一方のＥ鉄芯３′を打抜き後、他方のＥ
鉄芯３が自由となり、その取扱いが問題となる。 Therefore, if the band-shaped iron core plate 1 is made to have the same width t as the width of the E iron cores 3, 3', the formation of ears 5 will be eliminated, but after punching one E iron core 3', the other E iron core 3' will not be formed. E
The iron core 3 becomes free, and its handling becomes a problem.
この発明は、以上の点に鑑み、上記帯状鉄芯板

In order to solve the above problems, the present invention provides a manufacturing method in which the formation of protrusions and the punching and lamination of I-iron cores and E-iron cores are sequentially performed at each station, as described above, in which each station is positioned in a straight line. The above-mentioned strip-shaped iron core plate having the same width as the E iron core is floated on the straight line so that it can be lowered by the protrusion height of the above-mentioned protrusion from the upper surface of each lower die, and its width direction is regulated by a guide. While feeding, the first station forms the above protrusion, and the second station feeds the I.
The iron cores are punched and laminated as described above, and at the third station, one of the E iron cores whose front side becomes the notch is punched and laminated, and the other E iron core, which is freed by the punching, is rotated so as to come into contact with the upper surface of the E iron core. The tip edge of the other E iron core is brought into contact with the positioning stopper to position it in the feeding direction above the lower die, and the corner protruding toward the front from the positioning stopper is transferred to the fourth station by the body. The structure is such that the above-mentioned drop-in lamination is performed by fitting into the notch of the other E iron core and positioning it in the width direction on the lower die.
この様に構成するこの発明に係る製造方法にあ
つては、従来と同様にして、帯状鉄芯板の送り込
みによつて、Ｉ鉄芯及びＥ鉄芯が連続的に積層状
態で製作される。
In the manufacturing method according to the present invention configured as described above, the I iron core and the E iron core are manufactured in a continuous layered state by feeding the strip iron core plate in the same manner as in the conventional method.
この作用時、突起の突出分浮かして、帯状鉄芯
板を送るため、突起形成後においてもその送りは
円滑になされる。また、ポンチ作用時には、帯状
鉄芯は下降可能のため、その作用に支障がない。 During this action, the belt-shaped iron core plate is fed by floating the protruding portion of the protrusion, so that the feeding can be done smoothly even after the protrusion is formed. Further, during the punch action, the band-shaped iron core can be lowered, so there is no problem with the punch action.
切り離されて自由になつた他方のＥ鉄芯は、回
転体の回転により第４ステーシヨンまで確実に移
送される。また、その位置で送り方向及び幅方向
が位置決めされるため、下部ダイ内に確実に落と
し込まれて積層される。 The other E iron core, which has been separated and becomes free, is reliably transferred to the fourth station by the rotation of the rotating body. Furthermore, since the feed direction and width direction are determined at that position, the sheets are reliably dropped into the lower die and stacked.
なお、他方のＥ鉄芯を第４ステーシヨンまで移
送するのは、一方のＥ鉄芯の抜き落とし用下部ダ
イ（刃）の存在により、その抜き落としと同時に
他方のＥ鉄芯を下部ダイ内に落とし込み積層でき
ないからである。 The reason why the other E-iron core is transferred to the fourth station is because of the existence of a lower die (blade) for removing one E-iron core, the other E-iron core is simultaneously removed into the lower die. This is because drop-in lamination is not possible.
