Description

本発明はスラブの表面切削装置において、切削対象となるスラブを安定に支持することができるスラブ支持用定盤に関するものである。   The present invention relates to a slab support surface plate that can stably support a slab to be cut in a slab surface cutting apparatus.

連続鋳造されたスラブは、その表面に酸化スケール等の異物が付着しているため、スラブの表面切削装置により表面層の切削が行われる。例えば特許文献1に示されるように、スラブの表面切削はスラブ支持用定盤の上にスラブを載せてクランプし、スラブの上面に切削刃物を走行させて行われるのが一般的である。   The continuously cast slab has a surface layer cut by a surface cutting device of the slab because foreign matters such as oxide scale adhere to the surface. For example, as disclosed in Patent Document 1, surface cutting of a slab is generally performed by placing and clamping a slab on a slab supporting surface plate and running a cutting blade on the upper surface of the slab.

しかし、表面切削装置に搬入されるスラブは鋳造されたままの状態、あるいは圧延されたままの状態であるため、大きな反りや凹凸があるのが普通であり、必ずしも平板状ではない。このためスラブを左右方向のクランプのみで固定して切削作業を行うと、スラブが共振することがあり、切削面の品質に悪影響を及ぼすことがある。   However, since the slab carried into the surface cutting apparatus is in a cast state or a rolled state, it usually has a large warp and unevenness, and is not necessarily flat. For this reason, when the cutting operation is performed with the slab fixed only by the clamp in the left-right direction, the slab may resonate, which may adversely affect the quality of the cutting surface.

そこで従来はスラブの下面にくさびを打ち込み、そりや凹凸によって発生した床面とスラブとの隙間を埋めることによってスラブを固定し、切削中に発生する共振を抑制していた。しかしこのくさび打ち作業は機内においてハンマーとくさびを用いて行うため、被災リスクが高い作業であった。またこの作業が終了するまで切削を開始できないため、表面切削装置の稼働率の低下を余儀なくされていた。   Therefore, conventionally, a wedge is driven into the lower surface of the slab, and the slab is fixed by filling a gap between the floor surface and the slab generated by warpage or unevenness, thereby suppressing resonance generated during cutting. However, this wedge driving work was carried out using a hammer and a wedge in the machine, so the risk of damage was high. Moreover, since cutting cannot be started until this operation is completed, the operating rate of the surface cutting device has been reduced.

特開2004−17224号公報JP 2004-17224 A

従って本発明の目的は上記した従来の問題点を解決し、スラブに大きな反りや凹凸がある場合にも、くさび打ち作業を行うことなくスラブを安定的に支持することができるスラブ支持用定盤を提供することである。   Accordingly, the object of the present invention is to solve the above-mentioned conventional problems, and even when the slab has a large warp or unevenness, the slab support surface plate can stably support the slab without performing the wedge driving operation. Is to provide.

上記の課題を解決するためになされた本発明は、スラブの表面切削装置におけるスラブ支持用定盤であって、スラブの下面を支持する支持ビームを、所定間隔で複数本配置し、当該支持ビームの間に、スラブを幅方向にクランプするためのクランプ用シリンダが水平に配置されるとともに、スラブの幅方向の一方の端面には固定板が設けられ、当該クランプ用シリンダはスラブの幅方向に延びるシリンダロッドを備え、当該シリンダロッドの先端には、スラブを前記固定板に密着させてクランプするためのクランプ板が、前記支持ビーム上面よりも上方に立ち上がって固定され、前記支持ビームの間に、その一端が水平軸によってベースに固定され、他端が昇降用シリンダにより昇降自在とされ、個別に昇降されてスラブの下面を支持する昇降部材を複数配置し、これらの複数の昇降部材のうち前記固定板側の1つの昇降部材の水平軸の位置を、その他の昇降部材の水平軸の位置の反対側としたことを特徴とするものである。 The present invention made to solve the above problems is a slab support surface plate in a surface cutting apparatus for a slab, wherein a plurality of support beams supporting the lower surface of the slab are arranged at a predetermined interval, and the support beam A clamping cylinder for clamping the slab in the width direction is horizontally disposed, and a fixing plate is provided on one end surface in the width direction of the slab, and the clamping cylinder is arranged in the width direction of the slab. includes a cylinder rod extending to the distal end of the cylinder rod, the clamping plate for clamping in close contact with the slab to the fixing plate, rises upward is fixed than the support beam upper surface, between said support beams One end is fixed to the base by a horizontal shaft, and the other end is freely raised and lowered by a lifting cylinder. Those members plurality placed, the position of the horizontal axis of one of the lifting members of the fixed plate side of these plurality of lifting members, characterized in that the opposite side of the position of the horizontal axis of the other of the elevating member It is.

なお請求項2のように、前記支持ビームはスラブの幅方向に延びる部材であり、前記昇降部材はスラブの幅方向に延びる板状体であることが好ましく、請求項3のように、前記昇降部材はスラブの幅方向に複数個設けられていることが好ましい。また請求項4のように、前記昇降用シリンダは圧力スイッチを備え、昇降部材を所定の接触圧でスラブの下面に接触されるものであることが好ましく、さらに請求項5のように、上位コンピュータから伝送されるスラブのサイズにより、作動させる昇降用シリンダを決定することが好ましい。 As in claim 2, the support beam is a member extending in the width direction of the slab, and the lifting member is preferably a plate-like body extending in the width direction of the slab. It is preferable that a plurality of members are provided in the width direction of the slab. According to a fourth aspect of the present invention, the lifting cylinder preferably includes a pressure switch, and the lifting member is preferably brought into contact with the lower surface of the slab with a predetermined contact pressure. It is preferable to determine the lifting cylinder to be operated according to the size of the slab transmitted from the head.

本発明のスラブ支持用定盤は、スラブの下面を支持する支持ビームの間に、昇降用シリンダによって個別に昇降されてスラブの下面を支持する昇降部材を多数配置した構造であるから、スラブに大きな反りや凹凸がある場合にも、多数の昇降部材によってスラブの下面を自動的に、確実かつ安定に支持することができる。このため従来のような危険なくさび打ち作業をなくすことができ、安全性の向上を図ることができる。また従来はくさび打ち作業に15分程度の作業時間を要していたが、本発明によれば1秒程度の非常に短い時間でスラブを安定支持することができるので、表面切削装置の稼働率を向上させることができる。   The slab support surface plate of the present invention has a structure in which a large number of elevating members that are individually raised and lowered by the elevating cylinder and support the lower surface of the slab are arranged between the support beams that support the lower surface of the slab. Even when there are large warps or irregularities, the lower surface of the slab can be automatically and reliably supported stably by a large number of lifting members. For this reason, the conventional rusting operation can be eliminated without danger, and the safety can be improved. Conventionally, the wedge driving operation requires about 15 minutes. However, according to the present invention, the slab can be stably supported in a very short time of about 1 second. Can be improved.

なお、請求項4のように圧力スイッチによりスラブの下面への接触圧を設定しておけば、昇降部材に無理な力が作用することがない。また請求項5のように上位コンピュータから伝送されるスラブのサイズにより、作動させる昇降用シリンダを決定するようにすれば、動力の無駄を省くことができる。   In addition, if the contact pressure to the lower surface of the slab is set by the pressure switch as in claim 4, an unreasonable force does not act on the elevating member. Further, if the lifting cylinder to be activated is determined according to the size of the slab transmitted from the host computer as in claim 5, waste of power can be saved.

以下に本発明の好ましい実施形態を示す。
図1、図2に示すように、本実施形態のスラブ支持用定盤は、スラブSの幅方向に延びる細長い支持ビーム1を、スラブSの長手方向に所定間隔で複数本配置したものである。これらの支持ビーム1の上面は水平面を構成し、スラブSをその上に支持することができる。
Preferred embodiments of the present invention are shown below.
As shown in FIGS. 1 and 2, the slab support surface plate of the present embodiment has a plurality of elongated support beams 1 extending in the width direction of the slab S arranged at predetermined intervals in the longitudinal direction of the slab S. . The upper surfaces of these support beams 1 constitute a horizontal plane, and the slab S can be supported thereon.

本実施形態ではこれらの支持ビーム1の間に、スラブSを巾方向にクランプするためのクランプ用シリンダ2が水平に配置されている。これらのクランプ用シリンダ2はスラブSの幅方向に延びるシリンダロッド3を備えており、その先端に支持ビーム1の上面よりも上方に立ち上がるクランプ板4が固定されている。これらのクランプ板4はスラブSの幅方向の端面に接してスラブSを図1の図面上の上方に引き寄せ、固定板5に密着させてクランプする役割を持つ。   In this embodiment, a clamping cylinder 2 for clamping the slab S in the width direction is horizontally disposed between the support beams 1. These clamping cylinders 2 are provided with a cylinder rod 3 extending in the width direction of the slab S, and a clamp plate 4 rising above the upper surface of the support beam 1 is fixed to the tip thereof. These clamp plates 4 are in contact with the end face in the width direction of the slab S and have the role of drawing the slab S upward in the drawing of FIG.

これらの支持ビーム1の隣接位置には、図2、図3に示される昇降部材6が配置されている。昇降部材6はスラブSの幅方向に延びる板状体であり、スラブSの幅方向に複数個設けられている。本実施形態では幅方向に4個、長手方向に5列の全体で20個の昇降部材6が設けられている。しかしその個数は適宜設定することができる。   In the adjacent positions of these support beams 1, a lifting member 6 shown in FIGS. 2 and 3 is arranged. The lifting member 6 is a plate-like body extending in the width direction of the slab S, and a plurality of lifting members 6 are provided in the width direction of the slab S. In the present embodiment, four lifting members 6 are provided in a total of four rows in the width direction and five rows in the longitudinal direction. However, the number can be set as appropriate.

図3に示すように各昇降部材6はその一端が水平軸7によってベースに支持され、他端が昇降用シリンダ8により昇降自在とされている。このため各昇降部材6は端部を昇降させることができる。なお、本実施形態では、昇降用シリンダ8及びクランプ用シリンダ2は何れも油圧シリンダである。   As shown in FIG. 3, one end of each elevating member 6 is supported on the base by a horizontal shaft 7, and the other end can be raised and lowered by an elevating cylinder 8. For this reason, each raising / lowering member 6 can raise / lower an edge part. In the present embodiment, the lifting cylinder 8 and the clamping cylinder 2 are both hydraulic cylinders.

昇降用シリンダ8には圧力スイッチ(図示せず)が設けられており、各昇降部材6を所定の接触圧でスラブSの下面に接触させる。このためスラブSの下面に反りや凹凸がある場合にも、各昇降部材6はそれぞれ個別に上昇し、スラブSの下面に所定の接触圧で接した位置で停止する。この結果、支持ビーム1上に置かれたスラブSの下面全体を、確実に支持することができる。ただし必ずしも圧力スイッチを用いる必要はなく、全ての昇降用シリンダ8に一定の元圧を加えるようにしてもよい。   The lifting cylinder 8 is provided with a pressure switch (not shown), and each lifting member 6 is brought into contact with the lower surface of the slab S with a predetermined contact pressure. Therefore, even when the lower surface of the slab S is warped or uneven, the elevating members 6 are individually raised and stopped at a position in contact with the lower surface of the slab S with a predetermined contact pressure. As a result, the entire lower surface of the slab S placed on the support beam 1 can be reliably supported. However, it is not always necessary to use a pressure switch, and a constant source pressure may be applied to all the lifting cylinders 8.

図3に示すように、本実施形態では前記した固定板5側の昇降部材6のみ水平軸7の位置が他の3つの昇降部材6と反対側となっている。これによってスラブSの幅が狭い場合にも、スラブSの下面を確実に支持することができる。このように本実施形態では昇降部材6を水平軸7を中心として回転させる構造としたが、昇降用シリンダ8の先端に昇降部材6を直接取付け、上下方向に昇降させるようにしても差支えない。 As shown in FIG. 3, in the present embodiment, the position of the horizontal shaft 7 of only the lifting member 6 on the fixed plate 5 side is opposite to the other three lifting members 6. Thereby, even when the width of the slab S is narrow, the lower surface of the slab S can be reliably supported. As described above, in the present embodiment, the elevating member 6 is rotated around the horizontal shaft 7. However, the elevating member 6 may be directly attached to the tip of the elevating cylinder 8 and moved up and down.

なお、スラブSのサイズは様々であるが、工程を管理している上位コンピュータには全てのスラブのサイズが入力されている。このため、上位コンピュータから伝送されるスラブSのサイズにより、作動させる昇降用シリンダ8を決定するようにすれば、スラブSの下面に位置する昇降部材6のみを作動させることができ、動力の無駄を省くことができる利点がある。   Although the size of the slab S varies, the size of all the slabs is input to the host computer that manages the process. Therefore, if the lifting cylinder 8 to be operated is determined according to the size of the slab S transmitted from the host computer, only the lifting member 6 located on the lower surface of the slab S can be operated, and power is wasted. There is an advantage that can be omitted.

このようにして本発明のスラブ支持用定盤の上にスラブSを固定したうえ、その表面をフライスカッターにより切削する作業が行われるが、スラブSの下面は多数の昇降部材6により支持されているためがたつきが生じることはなく、共振やそれに伴う切削面の品質低下を防止することができる。また、昇降部材6の昇降は瞬時に行なうことができるので、従来のくさび打ち作業に要していた時間の無駄をなくすことができる。   In this manner, the slab S is fixed on the slab supporting surface plate of the present invention, and the work of cutting the surface with a milling cutter is performed. The lower surface of the slab S is supported by a number of lifting members 6. As a result, rattling does not occur, and resonance and the quality degradation of the cut surface associated therewith can be prevented. Moreover, since the raising / lowering of the raising / lowering member 6 can be performed instantly, the waste of time required for the conventional wedge driving operation can be eliminated.
