左右のカッターヘッド14、15の背面側にはカッター駆動用モータ21が配設され、このカッター駆動用モータ21で各カッターヘッド14、15にある合計6本の回転軸を複数の歯車を介して駆動するようになっている。各カッターヘッド14、15は、カッター18〜20の6本の回転軸の後端に個別に連結されたカッター進退用モータ22を有する。このカッター進退用モータ22によって各カッター18〜20をH形鋼Sに対する加工位置とH形鋼Sと干渉しない退避位置に選択的に移動させるようになっている。なお、カッター進退用モータ22に代えてシリンダを配設することも可能である。カッター進退用モータ22は開先加工量の調整用としても機能する。例えばスカラップ加工なし(ノンスカラップ加工)の場合は、カッター進退用モータ22でスカラップカッター19をH形鋼Sと干渉しない位置まで後退させた後、追い込みカッター18を通常よりもやや後退させた位置に移動して追い込み加工を行う。また、追い込みカッター18で形成したルート面の幅を調整したい場合、カッター進退用モータ22で開先カッター20の突き出し量を増減調節してルート面の幅を調整する。 On the back side of the left and right cutter head 14, 15 is arranged a cutter driving motor 21, the rotation axis of the total of six of this cutter driving motor 21 on each cutter head 14, 15 via a plurality of gears It comes to drive. Each cutter head 14, 15 has a cutter advance / retreat motor 22 individually connected to the rear ends of the six rotary shafts of the cutters 18-20. The cutter advancing / retreating motor 22 selectively moves each of the cutters 18 to 20 to a machining position for the H-section steel S and a retreat position that does not interfere with the H-section steel S. A cylinder may be provided instead of the cutter advance / retreat motor 22. The cutter advancing / retreating motor 22 also functions for adjusting the groove processing amount. For example, when there is no scallop processing (non-scallop processing), the cutter advance / retreat motor 22 moves the scallop cutter 19 back to a position where it does not interfere with the H-section steel S, and then moves the driving cutter 18 back to a position slightly retracted than usual. Then, it is driven. When the width of the route surface formed by the driving cutter 18 is to be adjusted, the width of the route surface is adjusted by adjusting the protrusion amount of the groove cutter 20 with the cutter advance / retreat motor 22.

次に、本発明の開先加工装置による加工について説明する。
図1に示すように、最初にカッター進退用モータ22を駆動して左右のカッターヘッド
14、15の後側のカッター18〜20をH形鋼Sと干渉しない位置まで後退させておく。また、このときカッターヘッド14、15は上昇させておく。この状態でH形鋼Sを図1で矢印A方向に搬送してその前端Eが二点鎖線で示す位置まで来るとH形鋼Sの搬送を停止する。次に、上クランプシリンダ9と下クランプシリンダ(図示せず)を駆動して押さえ治具10と受け治具12によってH形鋼Sのフランジ上下端を押圧し、これによってH形鋼Sを固定する(図4)。
Next, the process by the groove processing apparatus of this invention is demonstrated.
As shown in FIG. 1, the cutter advancing / retracting motor 22 is first driven to retract the rear cutters 18 to 20 of the left and right cutter heads 14 and 15 to a position where they do not interfere with the H-section steel S. At this time, the cutter heads 14 and 15 are raised. In this state, when the H-section steel S is conveyed in the direction of arrow A in FIG. 1 and its front end E reaches the position indicated by the two-dot chain line , the conveyance of the H-section steel S is stopped. Next, the upper clamp cylinder 9 and the lower clamp cylinder (not shown) are driven, and the upper and lower ends of the flange of the H-shaped steel S are pressed by the holding jig 10 and the receiving jig 12, thereby fixing the H-shaped steel S. (FIG. 4).

次に、カッター駆動用モータ21で各カッター18〜20を回転駆動し、昇降用モータ16によってカッターヘッド14、15を徐々に下降させ、追い込みカッター18、スカラップカッター19、開先カッター20の順にH形鋼Sに切り込んでいく。図7はスカラップカッター19によるスカラップ加工が終わって開先加工を行っている状態を示す。開先カッター20による面取り面の加工が終了すると、カッターヘッド14、15を元の高さ位置まで上昇させ、カッター駆動用モータ21を停止し、次いで進退用モータ22を駆動して前側の各カッター18〜20を後退させる。この状態でH形鋼Sのクランプを一旦解除し、H形鋼Sを前方に向けて搬送し、その後端が図6に示すように開先加工装置1の後側のカッター18〜20に対応した位置まで来たら搬送を停止する。そして前端加工時と同様に上クランプシリンダ9と下クランプシリンダ(図示せず)によってH形鋼Sを固定し、進退用モータ22で後側の各カッター18〜20を退避位置から前進させ、カッター駆動用モータ21で各カッター18〜20を回転駆動し、昇降用モータ16でカッターヘッド14、15を徐々に下降させていく。これによりH形鋼Sの前端と同様に後端が開先加工される。このようにしてH形鋼Sの前後両端の開先加工を行う。後端の開先加工が終わると、次のH形鋼Sの加工に備えてカッターヘッド14、15を元の高さ位置まで上昇させ、カッター駆動用モータ21を停止し、図5のように進退用モータ22を駆動してカッターヘッド14、15の後側の各カッター18〜20を退避させ、前側の各カッター18〜20を前進させる。 Next, each cutter 18-20 is rotationally driven by the cutter driving motor 21, and the cutter heads 14, 15 are gradually lowered by the lifting motor 16, and the driving cutter 18, the scallop cutter 19, and the groove cutter 20 are in the order of H. Cut into shape steel S. FIG. 7 shows a state in which groove processing is performed after scalloping by the scallop cutter 19 is finished. When the processing of the chamfered surface by the groove cutter 20 is completed, the cutter heads 14 and 15 are raised to their original height positions, the cutter driving motor 21 is stopped, and then the forward / backward motor 22 is driven to move each cutter on the front side. Retract 18-20. In this state, the clamp of the H-section steel S is once released, the H-section steel S is conveyed forward, and the rear end corresponds to the cutters 18 to 20 on the rear side of the groove processing apparatus 1 as shown in FIG. When it reaches the specified position, the conveyance is stopped. Then, similarly to the front end machining, the H-shaped steel S is fixed by the upper clamp cylinder 9 and the lower clamp cylinder (not shown), and the respective rear cutters 18 to 20 are advanced from the retracted position by the advance / retreat motor 22, and the cutter The cutters 18 to 20 are rotationally driven by the drive motor 21, and the cutter heads 14 and 15 are gradually lowered by the lift motor 16. As a result, the rear end is grooved in the same manner as the front end of the H-shaped steel S. In this way, groove processing is performed on both front and rear ends of the H-shaped steel S. When the rear end groove processing is finished, the cutter heads 14 and 15 are raised to their original height positions in preparation for the next processing of the H-shaped steel S, and the cutter driving motor 21 is stopped, as shown in FIG. The advancing / retreating motor 22 is driven to retract the respective cutters 18 to 20 on the rear side of the cutter heads 14 and 15 and advance the respective front cutters 18 to 20.
