本発明は鋼帯を巻回数ごとに異るピッチで、スロットを
打抜きなから巻芯に巻回してなる巻鉄心加工法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for processing a wound core in which a steel strip is punched out with slots and then wound around a core at a different pitch for each winding.
一般にこの種の巻鉄心は、巻き初めにあたって鋼帯の先
端を折り曲げ巻芯の溝に挿入、固定した後、打抜きなが
ら巻取っているため、巻芯と打抜刃との間にある鋼帯は
スロット部が打抜かれないまま巻回されていた。Generally, in this type of wound core, the tip of the steel strip is bent at the beginning of winding, inserted into the groove of the core, fixed, and then wound while being punched, so that the steel strip between the core and the punching blade is The slot part was wound without being punched out.
このため、第３図に示すように鋼帯を巻回後に前記巻き
初め部分の鋼帯４′を工具で除去せねばならない不都合
があった。For this reason, as shown in FIG. 3, after winding the steel strip, the steel strip 4' at the beginning of winding must be removed with a tool.
この作業は巻回された鉄心の内径部をさらに小径の環状
に巻くなどして工具の入る隙間をつくり、しかる後に切
除するため相当の時間を要し、生産性を著しく低減させ
る他、スクラップが増大し、材料の歩溜りを低下させて
いた。This process involves winding the inner diameter of the wound core into an annular shape with a smaller diameter to create a gap for the tool, and then cutting it out, which takes a considerable amount of time, significantly reduces productivity, and reduces scrap. This caused a decrease in material yield.
本発明はこれらの問題点を解決し、生産性を高め材料費
を低減するなど効果の高い加工法を提供するものである
。The present invention solves these problems and provides a highly effective processing method that increases productivity and reduces material costs.
以下、本発明の一実施例を第１図、第２図を参照して説
明する。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
第１図は本発明の加工法により製作した鉄心の構成を示
すもので、１は鉄心、２はスロット部、３はヨーク部、
４は全巻部である。Figure 1 shows the configuration of the core manufactured by the processing method of the present invention, where 1 is the core, 2 is the slot portion, 3 is the yoke portion,
4 is a complete volume.
第２図は加工装置を示すもので、５は打抜装置の打抜刃
６によりスロット２を打抜かれなから巻芯７に巻回積層
される鋼帯、８は打抜装置に連動された鋼帯送り装置で
ある。Figure 2 shows the processing equipment, in which 5 is a steel strip that is wound and laminated around a winding core 7 after the slot 2 is punched out by the punching blade 6 of the punching equipment, and 8 is linked to the punching equipment. It is a steel strip feeding device.
次に巻鉄心の製作工程を説明する。Next, the manufacturing process of the wound core will be explained.
まず、鋼帯５は、Ｐ点で打抜刃６によりスロット２を打
抜かれなから巻芯７に巻回積層される。First, the steel strip 5 is wound and laminated around the winding core 7 after the slot 2 is punched out by the punching blade 6 at point P.
このとき、Ｐ点で打抜かれたスロット２は、必ず巻芯７
の同一角度位置Ａ点に巻回積層されるように構成されて
いる。At this time, the slot 2 punched out at point P is always located at the core 7.
It is configured to be wound and laminated at the same angular position A point.
従来の方法によれば、この鋼帯５の巻初めに際し、第３
図に示すような巻初めの部分の鋼帯４′はスロット２の
ない巻鉄心となる。According to the conventional method, at the beginning of winding the steel strip 5, the third
The steel strip 4' at the beginning of the winding as shown in the figure becomes a wound core without slots 2.
なお、第４図は従来の加工方法を示すもので、図示する
如く巻初めの部分の鋼帯４′はスロット２が打抜かれな
いまま巻回され、巻回後、この巻き初め部分の鋼鉄除去
される。FIG. 4 shows a conventional processing method. As shown in the figure, the steel strip 4' at the beginning of the winding is wound without punching the slot 2, and after winding, the steel at the beginning of the winding is removed. be done.
すなわち、寸法１分の鋼板は、巻回後、除去され、スク
ラップとなる。That is, a steel plate having a size of 1 minute is removed after being wound and becomes scrap.
そこで本発明では、打抜刃６と連動した送り装置８によ
り鋼帯５を打抜刃６に送り込み、巻取芯７までの距離に
必要な長さ、すなわち、Ｐ点からＡ点までの長さ分を連
続打抜きしてヨーク部３だけを残した全巻部４を形成す
る様にするものである。Therefore, in the present invention, the steel strip 5 is fed to the punching blade 6 by a feeding device 8 linked to the punching blade 6, and the length required for the distance to the winding core 7, that is, the length from point P to point A, is The portions are continuously punched out to form a full-wound portion 4 with only the yoke portion 3 remaining.
このとき、送り装置８の鋼帯送すピッチは打抜刃６の巾
、すなわちスロワｌ−２の巾より若干小さい長さにセッ
トされる。At this time, the pitch at which the steel strip is fed by the feeding device 8 is set to a length that is slightly smaller than the width of the punching blade 6, that is, the width of the thrower l-2.
以上の説明から明らかなように本発明によればスロット
加工に必要なだけの簡単にして安価な金型がそのまま使
用でき、材料ロスがなく、後加工のいらない生産性の高
高い安価な巻鉄心を提供できる。As is clear from the above description, according to the present invention, a simple and inexpensive mold necessary for slot processing can be used as is, and a highly productive and inexpensive wound core with no material loss and no post-processing is required. can be provided.
