【発明の詳細な説明】
各種耐火煉瓦中特にスライディングノズルシステムに使
用されるスライドプレートなど特殊煉瓦の成形作業は最
近益々強圧化され、従って金型の中に投入される坏土の
密度分布の完全に均一であることが強く要求されるよう
になった。[Detailed Description of the Invention] In recent years, molding operations for special bricks such as slide plates used in sliding nozzle systems among various types of refractory bricks have become increasingly pressurized. There is now a strong demand for uniformity.
坏土分布が不均一になることはそのまま成形密度のバラ
ツキとなり、特に下辺に凸部のある特殊平板状の成形作
業においては圧縮過程における成形方向と垂直なる方向
の坏土の移動はほとんどないから密度の均一化を期待で
きない。Uneven distribution of clay leads to variations in molding density, and especially when molding a special flat plate shape with a convex portion on the lower side, there is almost no movement of clay in the direction perpendicular to the molding direction during the compression process. Uniform density cannot be expected.
そのことは真先に加圧充填された部分が最終加圧を抑制
し、もう一歩加圧充填せねばならない線部分をそれ以上
加圧できないのである。This means that the part that was pressurized first will suppress the final pressurization, and the line part that needs to be pressurized one more time cannot be pressurized any further.
このような不均一な坏土投入を防ぐため現在までは正確
に秤量された坏土な作業員が金型内に手動で投入した上
目見当と手さばきで適当にならして成形を行う例であっ
た。In order to prevent such uneven injection of clay, up until now, workers have manually poured the clay into the mold after accurately weighing the clay, and then used a rough guide and hand to properly level the clay and form it. there were.
この手でならすことが一つの秘伝ともいうような技術と
なり、それ故にこの種のプレートを製作するには、この
手動による原料投入が今のところ必須かつ最良のものと
されていたのである。Smoothing by hand became a secret technique, and for this reason, manual input of raw materials was considered essential and the best method for producing this type of plate.
然しながら最近労働環境に対するきびしい認識や法的規
制が行われ、又作業そのものに大きく個人差のあるやり
方に対する反省もあり、自動的、機械的操作方法が重要
な課題となってきた。However, in recent years, stricter recognition and legal regulations have been implemented regarding the working environment, and there has also been a reflection on the large individual differences in work methods, so automatic and mechanical operating methods have become an important issue.
本願発明はそれに対する自動坏土投入方法及び金型形式
の新しい提案である。The present invention is a new proposal for an automatic clay charging method and a mold type.
この提案の主眼点は第２図に示されるような凸部９をも
つ特殊プレート煉瓦３を成形するにあたり凸部９に対し
て如何にすれば平板部と同じように坏土を投入した後均
質に加圧成形するかという点、すなわち平板部と凸部の
成形密度を均一にすることがその重要な目的である。The main point of this proposal is that when molding a special plate brick 3 having convex portions 9 as shown in Fig. 2, how can the convex portions 9 be made homogeneous after being filled with clay in the same way as for the flat plate portions? The important objective is to make the molding density uniform between the flat plate portion and the convex portion.
本願発明者は従来の手動投入方式から近代的、自動的容
量チャージ方式へと機械化された場合、どういう不都合
な面があるか、これをカバーして、より均一な成形密度
を得るための基本的条件として、第１図に見らるる如く
金型は完全フローティング型面して上部プランジャーは
衝撃スクリューと油圧シリンダーよりなる公知の複合式
加圧方式を採用した。The inventor of this application aims to solve the disadvantages of mechanization from the conventional manual charging method to the modern automatic capacity charging method, and to solve the basic problems in order to obtain a more uniform molding density. As a condition, as shown in FIG. 1, the mold was a completely floating mold, and the upper plunger was a known composite pressurization system consisting of an impact screw and a hydraulic cylinder.
第２図に示すような一部に高さ２なる凸部９をもった厚
みＸなる板状成形物３を自動容量チャージの後成形する
場合、たとえば第３図に示す如く金型を板部２ｘ凸部２
ｚとして、成品寸法に対し同じ圧縮比をもたせる考慮を
せずこの点に特別の工夫をしないと、板部と凸部におけ
る坏土の初期体積と成形後体積の比、すなわち圧縮比が
異るものとなり、そのため成形後凸部の境界でひび割れ
が起きまた凸部の締り不足等の欠陥がどうしてもまぬが
れない。When molding a plate-like molded product 3 having a thickness of X and having a convex portion 9 with a height of 2 in a part as shown in FIG. 2 after automatic capacitance charging, for example, as shown in FIG. 2x convex part 2
As for z, unless consideration is given to giving the same compression ratio to the product dimensions and no special measures are taken in this respect, the ratio of the initial volume of the clay to the volume after molding in the plate part and the convex part, that is, the compression ratio will be different. As a result, cracks occur at the boundaries of the convex parts after molding, and defects such as insufficient tightening of the convex parts cannot be avoided.
本願発明は第１図に見られる如く下部パンチ６は上面に
金型４を嵌装しかつ凸部９の底部に対し開口し凸部高さ
と同じ３寸法だけロッド５の上部に余分に坏土が入る様
にして、通常の容量チャージ方式で坏土を投入する。In the present invention, as shown in FIG. 1, the lower punch 6 has a mold 4 fitted on its upper surface and is open to the bottom of the convex part 9, and an extra mold is placed on the top of the rod 5 by three dimensions equal to the height of the convex part. Insert the clay using the normal capacity charging method.
而してロッド５は下部テーブル８に固定され下パンチ６
に対しては滑合するものとする。The rod 5 is fixed to the lower table 8 and the lower punch 6
It is assumed that there is a sliding fit for
図ではフローティング構造の金型４が下部シリンダー■
により上限に支持されその状態に於て坏土がチャージャ
ーで充填され、凸部９の下側の開口はピン５の上面が３
寸法だけ下位にある如く固定される。In the figure, the floating structure mold 4 is the lower cylinder■
In this state, the clay is filled with the charger, and the lower opening of the convex part 9 is opened so that the upper surface of the pin 5 is 3.
It is fixed as if it were lower only by its dimensions.
ピン５に滑合する下パンチ６はシリンダー７によって支
持され凸部に対する坏土の充填深さは２ｚになる如（す
る。The lower punch 6, which is slidably fitted onto the pin 5, is supported by the cylinder 7, so that the filling depth of the clay into the convex portion is 2z.
次に第１図に於て上部予圧シリンダー■が発動し、それ
に垂下したプランジャー２及び上部プレスブロック１が
矢印の如く降下して金型の支持位置はそのままにして先
づ金型上部より坏土を加圧する。Next, in Fig. 1, the upper preload cylinder (■) is activated, and the plunger 2 and the upper press block 1 that hang down from it descend as shown by the arrows, leaving the supporting position of the mold as it is and starting from the upper part of the mold. Pressurize the soil.
続いて衝撃式スクリュー加圧作用が始まるとフローティ
ング式金型４及び下パンチ６の支持シリンダー７の圧力
を減じて下降させ余分の加圧穴Ｘ及び２はゼロとなる。Subsequently, when the impact type screw pressurizing action starts, the pressure of the floating mold 4 and the supporting cylinder 7 of the lower punch 6 is reduced and lowered, and the extra pressurizing holes X and 2 become zero.
衝撃による加圧力は予圧の数倍〜数十倍となるが下パン
チ６と下部テーブル８がこれを受けとめ結局平板部と凸
部の圧縮比は同一となるから成品全体は均一な加圧力が
加えられるのである。The pressing force due to the impact is several times to several tens of times the preload, but the lower punch 6 and the lower table 8 receive this, and the compression ratio of the flat plate part and the convex part becomes the same, so a uniform pressing force is applied to the entire product. It will be done.
尚機械的容量チャージャーで平板部及び凸部に均一に坏
土を投入することが長い経験と特別のノウハウによらず
ども十分可能であることは既に毎日の実地生産現場にお
いて実証済みである。It has already been proven in daily production sites that it is possible to uniformly inject clay into flat plate parts and convex parts using a mechanical capacity charger without relying on long experience or special know-how.
成形が完了すｉｆ金型４を細鎖線位置まで引下げること
により、成形物は金型から抜出され、更にこれをピック
アップ装置で取り出すことはきわめて容易である。If molding is completed, the molded product is pulled out from the mold by pulling down the mold 4 to the position shown by the thin chain line, and it is very easy to take out the molded product using a pickup device.
尚坏土３の投入深さ２Ｘ２Ｚはフローチング式金型４の
上下調整によって調節されることは従来の機械と同様で
ある。As with conventional machines, the feeding depth 2X2Z of the clay 3 is adjusted by vertically adjusting the floating mold 4.
上述の如く本発明にかかわる新酸形装置によれば平板部
も凸部も同じ圧縮比に加圧され、煉瓦全体の密度にバラ
ツキが無く強靭で均質な成品を得ることが十分期待され
る。As mentioned above, according to the new acid molding device according to the present invention, both the flat plate portion and the convex portion are pressurized to the same compression ratio, and it is fully expected that a tough and homogeneous product with no variation in the density of the brick as a whole can be obtained.
その構造の簡単なことと調節自在であることが、価格安
（操作の容易である利益をもたらすことは重要である。It is important that the structure is simple and adjustable, resulting in the advantage of low cost (and ease of operation).
