明細書 ' 板厚圧下プレス装置の金型ギヤップ調整装置 発明の背景  Description '' Die Gap Adjustment Device for Plate Thickness Pressing Machine Background of the Invention
発明の技術分野 TECHNICAL FIELD OF THE INVENTION
本発明は、 1パスで高圧下が可能な板厚圧下プレス装置の金型ギヤップ調整装 置に関する。 関連技術の説明  The present invention relates to a die gap adjusting device of a plate thickness reduction press device capable of reducing pressure in one pass. Description of related technology
1パスで高圧下が可能な圧延手段として、 従来の幅圧下プレスを板厚圧下に適 用したプレス装置が提案されている （例えば、 特公平 2— 0 1 4 1 3 9号、 特開 昭 6 1— 2 2 2 6 5 1号、 特開平 2— 1 7 5 0 1 1号、 等）。  As a rolling means capable of high-pressure reduction in one pass, a press apparatus in which a conventional width reduction press is applied for thickness reduction has been proposed (for example, Japanese Patent Publication No. 2-0141139, 6 1- 2 2 265 1, Japanese Unexamined Patent Application Publication No. 2-175011, etc.).
例えば、 特開平 2— 1 7 5 0 1 1号の 「走間サイジングプレス装置」 は、 図 1 に示すように、 被成形材料搬送ライン Zの上方と下方、 あるいは左方と右方に回 転軸 4を配設し、 この回転軸 4の偏心部に所要の形状のコンロッド 3のボス部を 嵌合するとともに、 コンロッド 3の先端部に被成形材料搬送ライン Zと対峙する ように配設した金型 2を連結したものであり、 回転軸 4を回動させ、 回転軸の偏 心部に嵌合したコンロッド 3を介して金型 2を被成形材料 1 (スラブ） の上下両 面に圧下させてスラブ 1の厚さを減じるようになつている。 この場合、 金型 2の 上下ストロークは、 回転軸 4の偏心量で決まり、 回転軸 4の回転中心が一定であ る限り、 圧下後のスラブ 1の厚さ hは一定となる。  For example, as shown in Fig. 1, the "running sizing press" disclosed in Japanese Patent Application Laid-Open No. 2-175001 is rotated to above and below the material conveying line Z, or to left and right. A shaft 4 is provided, a boss of a connecting rod 3 having a required shape is fitted to an eccentric portion of the rotating shaft 4, and a leading end of the connecting rod 3 is provided so as to face the material transfer line Z. The mold 2 is connected. The rotating shaft 4 is rotated, and the mold 2 is pressed down on the upper and lower surfaces of the material 1 (slab) via the connecting rod 3 fitted to the eccentric portion of the rotating shaft. Then, the thickness of the slab 1 is reduced. In this case, the vertical stroke of the mold 2 is determined by the amount of eccentricity of the rotary shaft 4, and the thickness h of the slab 1 after the reduction is constant as long as the rotation center of the rotary shaft 4 is constant.
また、同様の目的で図 2に例示する圧下プレスを用いることも考えられている。 この装置は、 スラブ 1を挟んで上下に設けた金型 2と、 各金型ごとに設けられ金 型を上下および前後に揺動させるスライダー 8と、 このスライダーを駆動する駆 動装置とを備え、 前記スライダーは、 スラブ幅方向に中心軸を有する円孔が設け られたスライダー本体 8 aと、 この円孔に嵌合する第 1軸 9 aとこの第 1軸より 小径の第 2軸 9 bで第 1軸と中心軸をずらして構成されたクランク 9とを有し、 この第 2軸が前記駆動装置で回転駆動されるものである。  It is also considered to use a draft press illustrated in FIG. 2 for the same purpose. This device includes a mold 2 provided vertically above and below a slab 1, a slider 8 provided for each mold to swing the mold up and down and back and forth, and a driving device for driving the slider. The slider includes a slider body 8a provided with a circular hole having a central axis in the slab width direction, a first shaft 9a fitted into the circular hole, and a second shaft 9b smaller in diameter than the first shaft. And a crank 9 having a first axis shifted from a center axis, and the second axis is rotationally driven by the driving device.
この構成により、 第 2軸 9 bが回転すると第 1軸 9 aは第 2軸の軸心を中心に クランク動作を行い、 嵌合した円孔によりスライダー本体 8 aに上下、 前後動'を 与える。 これによりスライダー 8は金型を圧下し、 かつ圧下中は金型に前進運動 を与えることができるので、 スラブ 1は圧下されつつ前進 （スラブ流れ方向） 作 用を受けるので連続的な圧下動作が可能になる。 また、 この発明はスラブ 1の上 下両方から金型 2で圧下するので、 大きな圧下量を与えることができる。 なおこ の図で、 6はピンチロール、 7は搬送テーブルである。 With this configuration, when the second shaft 9b rotates, the first shaft 9a rotates around the axis of the second shaft. The crank operation is performed, and the slider body 8a is moved up and down and back and forth by the fitted circular hole. As a result, the slider 8 can press down the mold and apply a forward movement to the mold during the press-down, so that the slab 1 is subjected to the forward operation (slab flow direction) while being pressed down, so that the continuous press-down operation is performed. Will be possible. Further, in the present invention, since the die 2 is pressed down from both the upper and lower sides of the slab 1, a large amount of reduction can be given. In this figure, 6 is a pinch roll and 7 is a transfer table.
更に、 図 3は、 クランクとコンロッドを用いた例であり、 スラブ 1を挟んで上 下に設けられた金型 2にはコンロッド 3を介してクランク 4が接続され、 金型 2 を上下に揺動して圧下する。 この場合にも、 金型 2の上下ストロークは、 クラン ク 4の偏心量で決まり、 クランク 4の回転中心が一定である限り、 圧下後のスラ ブ 1の厚さ hは一定となる。  Fig. 3 shows an example in which a crank and a connecting rod are used. A crank 4 is connected to a mold 2 provided above and below the slab 1 via a connecting rod 3, and the mold 2 is swung up and down. Move and reduce. Also in this case, the vertical stroke of the mold 2 is determined by the amount of eccentricity of the crank 4, and the thickness h of the slab 1 after reduction is constant as long as the rotation center of the crank 4 is constant.
なお、 その他にも、 1パスで高圧下が可能な板厚圧下プレス装置として、 種々 の形式の高圧下手段が、 本願発明の発明者等により提案されている。  In addition, various types of high-pressure reduction means have been proposed by the inventors of the present invention as a plate thickness reduction press apparatus capable of performing high-pressure reduction in one pass.
しかし、 上述したように、 1パスで高圧下が可能な板厚圧下プレス装置では、 上下の金型の上下動をカム又はクランクを用いて行うため、 上下の金型の圧下ス トロークは常に一定になる。 そのため、 同一の金型を用いる限り、 圧下後の板厚 が一定であり高圧下後の板厚調整が困難である問題点があった。 発明の要約 本発明は上述の問題点に鑑みてなされたもので、 同一の金型を用いて、 高圧下 後の板厚を容易に調整することができる板厚圧下プレス装置の金型ギヤップ調整 装置を提供することを目的とする。  However, as described above, in a plate thickness reduction press that can perform high pressure reduction in one pass, since the upper and lower dies are moved up and down using a cam or a crank, the reduction stroke of the upper and lower dies is always constant. become. Therefore, as long as the same die is used, there is a problem that the thickness after the reduction is constant and it is difficult to adjust the thickness after the reduction. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a die gap adjustment of a plate thickness reduction press device capable of easily adjusting a plate thickness after high pressure using the same die. It is intended to provide a device.

The distance between the rotation centers of the eccentric shaft and the crankshaft can be changed. Therefore, since the upper and lower molds have the same reduction stroke, and even if the same mold is used, the respective stroke ranges change, so that the thickness of the plate after the reduction can be freely adjusted. In other words, by reducing the interval between the rotation centers of the upper and lower eccentric shafts or the crankshaft, the thickness after high pressure can be reduced, and conversely, by increasing the interval between the rotation centers, the thickness after high pressure can be increased. .
