本発明は自動車用ウェルトの芯金等に用いられる鋼製芯
材の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a steel core material used for a core metal of an automobile welt.

できる様になされている。Is automotive welt used for automobiles? This is a component made of thermoplastic resin or rubber and having a shape roughly shown in FIG. This welt 1 is attached to a U-shaped base 2 at a connecting portion 4' as shown in FIG.
The core bar 3 includes a core bar 3 in which grooves 4 are bored at a predetermined pitch in the longitudinal direction over the entire width, leaving the entire width, so that it can be bent at any position in the longitudinal direction.

拡大する方法が一般的であった０
しかし々から、この様な打抜プレスによると、芯金材と
して軟鋼のみの使用を余儀なくされ、また打抜いた部分
がムダとなり資源の有効利用の面から好ましくない。Conventionally, the method for producing this type of core metal is to first punch a small groove in the thin strip steel using a punching press,
It was common practice to then roll the entire thin steel strip using rolling rolls to enlarge the grooves. However, with such a punching press, only mild steel had to be used as the core material. Furthermore, the punched parts become wasteful, which is not desirable from the standpoint of effective use of resources.
また、打抜操作と帯鋼送給操作とを同期させる機構を別

する遅速操作を余儀なくされ＼芯金製造の連続化、高速
化が果たせ々いという欠点があった。更に、連結部４′
は切損しにくいため、ウェルトが屈曲しにくいといった
欠点があった。In addition, it is necessary to separately provide a mechanism to synchronize the punching operation and the strip feeding operation, which is complicated in terms of equipment and operation.Also, the punching operation itself is slow and requires a considerable amount of time to go back and forth. The drawback was that it was difficult to achieve continuous and high-speed core metal manufacturing because of the forced operation. Furthermore, the connecting portion 4'
Since it is difficult to cut and break, it has the disadvantage that the welt is difficult to bend.

供するものである。The present invention has been made in view of these conventional drawbacks, and includes: a feeding roller for thin strip steel; A pair of gear bodies that shear the entire width of the thin steel strip at a predetermined pitch in the longitudinal direction, leaving a connection part along the gear body, and a chisel-shaped protrusion that is pressed against the connection part of the thin steel band that passes through this gear body. and a pair of rolling rollers that have been modified, and the gear body is provided with in&lj neat teeth adjacent to each other with a small width of thin strip steel near the pitch circle, at a pitch of one to several times the shear pitch. The present invention provides an apparatus for manufacturing a core material, which is characterized by a gear body having a shape of a cylindrical shape.
