Description

本発明は、半凝固金属スラリー製造装置と、それで作った半凝固金属スラリーを用い、金属成形体を得る金型を装着した成形装置とを具備したレオキャスト設備に関する。   The present invention relates to a rheocast facility comprising a semi-solid metal slurry manufacturing apparatus and a molding apparatus equipped with a mold for obtaining a metal molded body using a semi-solid metal slurry produced therefrom.

近年、自動車用部品や携帯情報機器用部品などの各種部品がアルミニウム合金やマグネシウム合金などの半凝固金属スラリーを用い、ダイキャストや溶湯鍛造により作られている。これは半凝固加工法により、結晶粒が球状でマクロ偏析や収縮巣がなく、優れた機械的性質が得られるからである。
この種の半凝固加工法では、半凝固金属スラリー製造装置で作った金属スラリーが半凝固域にある状態で成形装置に供給するレオキャスト法と、半凝固金属スラリーを一旦凝固させてビッレト状とし、それを半溶融温度域に再加熱して加工するチクソキャスト法が知られ、前者のレオキャスト法が再加熱する必要がないことから、省エネルギー性に優れた加工法である。それに用いる半凝固金属スラリーは、結晶粒が液相マトリックス中に互いに分離した状態で存在し球状であることが、良好な金属成形体を得るうえで、必要である。 In recent years, various parts such as automobile parts and portable information equipment parts are made by die casting or molten metal forging using semi-solid metal slurry such as aluminum alloy or magnesium alloy. This is because the semi-solidified processing method makes it possible to obtain excellent mechanical properties because the crystal grains are spherical and there is no macro segregation or shrinkage.
In this type of semi-solid processing method, the metal slurry made by the semi-solid metal slurry production equipment is supplied to the molding equipment in a state where it is in the semi-solid zone, and the semi-solid metal slurry is once solidified into a biteto shape. A thixocast method is known in which it is reheated to a semi-melting temperature range and processed, and the former rheocast method does not need to be reheated. The semi-solid metal slurry used for it is necessary to obtain a good metal formed body in which the crystal grains are present in a separated state in the liquid phase matrix and are spherical.

そのため、従来から、各種の半凝固金属スラリーの製造方法が提案されている（例えば特許文献１）。この特許文献１に記載の製造方法は、図４に示すような半凝固金属スラリー製造装置１を用い、ほぼ球状化した微細な結晶粒を得るために、溶融金属（溶湯ともいう）を傾斜冷却体１Ａ上に流下して急冷し、次いで保持容器３内で保持する方法である。
なお、溶融金属保持炉１Ｃで保持した溶湯は、当該アルミニウム合金の液相線温度ＴL（℃）からＴL＋６０（℃）の間の温度で傾斜冷却体１Ａと接触させ、当該溶融金属の少なくとも一部を固液共存状態とすると共に、細粒で粒状の１次粒子を晶出させ、その後、保持容器３内で１次粒子が晶出した溶湯を半溶融温度域に所定の時間保持し、半凝固金属スラリーとしている。この半凝固金属スラリー製造装置１では、溶融金属保持炉１Ｃ内に制御棒を浸漬させ、溶融金属保持炉１Ｃ内の溶湯を、図４に示したように、給湯管１Ｂを経て傾斜冷却体１Ａ上に流下させ、回転テーブル１１上の保持容器３で受けるのが普通である。 Therefore, conventionally, various methods for producing semi-solid metal slurry have been proposed (for example, Patent Document 1). The manufacturing method described in Patent Document 1 uses a semi-solid metal slurry manufacturing apparatus 1 as shown in FIG. 4 to incline cool molten metal (also referred to as molten metal) in order to obtain almost spherical particles. It is a method of flowing down on the body 1A, quenching, and then holding in the holding container 3.
The molten metal held in the molten metal holding furnace 1C is brought into contact with the inclined cooling body 1A at a temperature between the liquidus temperature T L (° C.) and T L +60 (° C.) of the aluminum alloy, and the molten metal At least a part is in a solid-liquid coexistence state, and fine and granular primary particles are crystallized, and then the molten metal in which the primary particles crystallize in the holding container 3 is held in a semi-melting temperature range for a predetermined time. And semi-solid metal slurry. In this semi-solid metal slurry manufacturing apparatus 1, the control rod is immersed in the molten metal holding furnace 1C, and the molten metal in the molten metal holding furnace 1C passes through the hot water supply pipe 1B and the inclined cooling body 1A as shown in FIG. Usually, it flows down and is received by the holding container 3 on the rotary table 11.

従来の金属スラリーの搬送装置は、回転テーブル１１の円周上に沿って保持容器３が複数個並べられ、回転中心１１Ａ周りの回転テーブル１１の回転に伴って保持容器３が順次、傾斜冷却体１Ａの下端にて流下する溶湯を受ける位置に来るようになっている。
特開平８−１８７５４７号公報 In the conventional metal slurry transfer device, a plurality of holding containers 3 are arranged along the circumference of the rotary table 11, and the holding containers 3 are sequentially inclined as the rotary table 11 rotates around the rotation center 11A. It comes to the position which receives the molten metal which flows down in the lower end of 1A.
JP-A-8-187547

しかしながら、従来の回転テーブル方式の半凝固金属搬送装置は、回転テーブル１１の回転に伴って保持容器３が順次、傾斜冷却体１Ａの下端にて流下する溶湯を受ける位置に来るようにしなければならず、また、回転テーブル１１の円周上に沿って保持容器３が複数個並べられているため、大型となる。したがって、これを具備したレオキャスト設備に広い設置スペースを要するという欠点があった。   However, in the conventional semi-solid metal transport device of the rotary table type, as the rotary table 11 rotates, the holding container 3 must sequentially come to a position for receiving the molten metal flowing down at the lower end of the inclined cooling body 1A. Furthermore, since a plurality of holding containers 3 are arranged along the circumference of the rotary table 11, the size becomes large. Therefore, there is a drawback that a large installation space is required for the rheocast equipment equipped with this.

また、従来の回転テーブル方式の半凝固金属搬送装置と、溶湯鍛造装置やダイキャスト装置などの金型を装着した成形装置２とを具備したレオキャスト設備の場合には、回転テーブル１１の回転に伴って成形装置２の近くに来た保持容器３を人手で持ち上げ、図５に示したように、金型を装着した成形装置２の湯口部に、半凝固金属スラリーが流下するよう保持容器３を傾斜させていた。   Further, in the case of a rheocast facility equipped with a conventional rotary table type semi-solid metal transfer device and a molding device 2 equipped with a mold such as a molten metal forging device or a die cast device, the rotary table 11 is rotated. Along with this, the holding container 3 that comes close to the molding apparatus 2 is manually lifted, and as shown in FIG. 5, the holding container 3 so that the semi-solid metal slurry flows down to the gate of the molding apparatus 2 equipped with a mold. Was tilted.

このため、成形装置２の湯口部へ半凝固金属スラリーを供給する作業者の作業負荷が大きく、熟練した作業者でも成形装置２の湯口部へ半凝固金属スラリーを安定して供給するのが難しいという欠点があった。これを解消するため、傾斜冷却体１Ａで溶湯を冷却する半凝固金属スラリー製造装置１と、それで作った半凝固金属スラリーを用い、金属成形体を得る金型を装着した成形装置２とを具備したレオキャスト設備にロボットを導入し、保持容器３を持ち上げ、傾斜させて半凝固金属スラリーを成形装置２に供給する作業などを行うことも考えられるが、それを導入した場合、設置スペースが余分に必要になると共に高度な機械を扱うには熟練を要するという問題が発生してしまう。   For this reason, the work load of the operator who supplies the semi-solid metal slurry to the gate of the molding apparatus 2 is large, and it is difficult for a skilled worker to stably supply the semi-solid metal slurry to the gate of the molding apparatus 2. There was a drawback. In order to solve this problem, the semi-solid metal slurry manufacturing apparatus 1 for cooling the molten metal with the inclined cooling body 1A and the molding apparatus 2 equipped with a mold for obtaining a metal molded body using the semi-solid metal slurry made therewith are provided. It is conceivable to introduce a robot into the Rheocast equipment, lift the holding container 3 and tilt it to supply the semi-solid metal slurry to the molding apparatus 2. In addition, a problem arises that skill is required to handle sophisticated machines.

本発明は、上記従来技術の問題点を解消し、半凝固金属スラリーを、金型を装着した成形装置に容易にかつ安定して供給することで、品質が一定した金属成形体を得ることができるコンパクトなレオキャスト設備を提供することを目的とする。   The present invention eliminates the above-mentioned problems of the prior art, and can easily and stably supply a semi-solid metal slurry to a molding apparatus equipped with a mold to obtain a metal molded body having a constant quality. The purpose is to provide a compact rheocasting facility.

本発明は、傾斜冷却体で溶湯を冷却する半凝固金属スラリー製造装置と、該半凝固金属スラリー製造装置で作った半凝固金属スラリーを用い、金属成形体を得る金型を装着した成形装置とを近接配置し、かつ前記半凝固金属スラリーを保持する保持容器を１とし、該１つの保持容器を、前記傾斜冷却体の下端にて流下する溶湯を前記保持容器で受ける位置から前記成形装置の湯口部の上方であって前記保持容器底部の流出口より流下させた半凝固金属スラリーを自重により成形装置へ供給できる位置までの間にわたり、往復動可能とする搬送手段を設けたことを特徴とするレオキャスト設備である。
The present invention relates to a semi-solid metal slurry production apparatus for cooling molten metal with an inclined cooling body, and a molding apparatus equipped with a mold for obtaining a metal molded body using the semi- solid metal slurry produced by the semi- solid metal slurry production apparatus , and The holding container for holding the semi-solid metal slurry is set as 1, and the holding apparatus receives the molten metal flowing down at the lower end of the inclined cooling body from the position where the holding container receives the molten metal. It is characterized in that a conveying means is provided that can reciprocate over a position above the gate and to a position where the semi-solid metal slurry flowed down from the outlet at the bottom of the holding container can be supplied to the molding apparatus by its own weight. This is a Leocast facility.

前記保持容器は、切り欠き部を形成した固定蓋と、前記切り欠き部を塞ぐスライド蓋とで開口部の蓋ができることが好ましく、またさらに切り欠き部を形成した固定蓋と、容器底部の流出口を塞ぐ棒状ストッパーとを有し、前記固定蓋に棒状ストッパーが上下動できるガイド孔を設けてなり、前記固定蓋のガイド孔に挿入した棒状ストッパーで容器底部の流出口を塞いだものとするのが好ましい。 The holding container includes a fixed cover forming the notches, it is preferred that the lid of the opening in the slide cover for closing the cutout portion and a fixed lid further formed notches, the flow of the container bottom It has a rod-shaped stopper that closes the outlet, and is provided with a guide hole in which the rod-shaped stopper can move up and down in the fixed lid, and the outlet at the bottom of the container is blocked by the rod-shaped stopper inserted into the guide hole of the fixed lid Is preferred.

本発明にかかるレオキャスト設備によれば、傾斜冷却体で溶湯を冷却する半凝固金属スラリー製造装置と、金型を装着した成形装置とを近接配置し、半凝固金属スラリーを保持する保持容器を１つとし、それを往復動可能とする搬送手段を設けたので、コンパクトなレオキャスト設備とすることができる。
また、一つの保持容器の往復動する範囲を、前記傾斜冷却体の下端にて流下する溶湯を保持容器で受ける位置から前記成形装置の湯口部の上方近傍、すなわち容器底部の流出口より流下させた半凝固金属スラリーを自重により成形装置へ供給できる位置までの間としたから、金型を装着した成形装置に容易にかつ安定して半凝固金属スラリーを供給できる。このため、結晶粒がほぼ球状でマクロ偏析や収縮巣が少なく、品質が一定した金属成形体を得ることが可能となる。 According to the rheocast equipment according to the present invention, a semi-solid metal slurry production device that cools the molten metal with an inclined cooling body and a molding device equipped with a mold are arranged close to each other, and a holding container that holds the semi-solid metal slurry is provided. Since one is provided and a conveying means that can reciprocate it is provided, a compact rheocast facility can be obtained.
Further, the reciprocating range of one holding container is caused to flow down from the position where the molten metal flowing down at the lower end of the inclined cooling body is received by the holding container, near the upper part of the pouring part of the molding apparatus, that is, from the outlet at the bottom of the container. Since the semi-solid metal slurry is set to a position where it can be supplied to the molding apparatus by its own weight, the semi-solid metal slurry can be easily and stably supplied to the molding apparatus equipped with a mold. For this reason, it is possible to obtain a metal molded body having substantially uniform crystal grains, less macro segregation and shrinkage, and a constant quality.

以下に、図面を用い、本発明にかかるレオキャスト設備について説明する。図１は、本発明にかかるレオキャスト設備の構成の一例を示す側面図であり、図２は、図１に示したレオキャスト設備の平面図である。
本発明にかかるレオキャスト設備は、傾斜冷却体１Ａで溶湯を冷却する半凝固金属スラリー製造装置１と、金属成形体を得る金型を装着した成形装置２とを近接配置し、半凝固金属を保持する一つの保持容器３を所定の範囲にわたり、往復動可能とする搬送手段６を設けたことを特徴とする。この場合、搬送手段６は、図１中に示した移動距離Ｌの範囲内で、レール部材７上を往復移動する移動台６であり、一つの保持容器３が移動台６に搭載されている。移動距離Ｌは、保持容器３が斜冷却体１Ａの下端にて流下する溶湯を受ける位置から成形装置２の金型へ至る湯口部の上方近傍位置、すなわち、容器底部の流出口より流下させた半凝固金属スラリーを自重により成形装置２へ供給できる位置までの間である。なお、保持容器３には、流出口と連通させて傾斜連結管５が設けられている。容器底部の流出口は上下動可能な棒状ストッパー４で塞ぐのが好ましい。 Below, the rheocasting equipment concerning the present invention is explained using a drawing. FIG. 1 is a side view showing an example of the configuration of the rheocast equipment according to the present invention, and FIG. 2 is a plan view of the rheocast equipment shown in FIG.
The rheocast equipment according to the present invention includes a semi-solid metal slurry manufacturing apparatus 1 that cools a molten metal with an inclined cooling body 1A and a molding apparatus 2 that is equipped with a mold for obtaining a metal molded body, so that the semi-solid metal is disposed. The present invention is characterized in that a conveying means 6 is provided that enables one holding container 3 to be held to reciprocate over a predetermined range. In this case, the conveying means 6 is a moving table 6 that reciprocates on the rail member 7 within the moving distance L shown in FIG. 1, and one holding container 3 is mounted on the moving table 6. . The moving distance L was made to flow down from the position near the upper part of the gate from the position where the holding container 3 receives the molten metal flowing down at the lower end of the inclined cooling body 1A to the mold of the molding apparatus 2, that is, from the outlet at the bottom of the container. This is until the position where the semi-solid metal slurry can be supplied to the molding apparatus 2 by its own weight. The holding container 3 is provided with an inclined connecting pipe 5 that communicates with the outflow port. The outlet at the bottom of the container is preferably closed with a bar-like stopper 4 that can move up and down.

ここで、一つの保持容器３を搭載した移動台６は、２つのレール部材７によって移動方向１０と直角な２方向への移動が規制されている。また一つの保持容器３を搭載した移動台６は、移動台６に搭載したモータを回転させ、モータを正転、逆転させ、移動距離Ｌの範囲内で往復移動するようになっている。
図１、２中、８、９は支持部材であり、２つのレール部材７を介して、移動台６に搭載された保持容器３の高さ方向位置が、半凝固金属スラリー製造装置１の側では、斜冷却体１Ａの下端にて流下する溶湯を受ける高さとなり、成形装置２の側では、湯口部の上方にその底部が位置するように調整されていると共に、金属成形体に必要な量の溶湯を保持したときの一つの保持容器３と、それを搭載した移動台６とを支持している。 Here, the movement table 6 on which one holding container 3 is mounted is restricted from moving in two directions perpendicular to the movement direction 10 by two rail members 7. In addition, the movable table 6 on which one holding container 3 is mounted is configured such that a motor mounted on the movable table 6 is rotated, and the motor is rotated forward and backward so as to reciprocate within the range of the moving distance L.
In FIGS. 1 and 2, reference numerals 8 and 9 denote support members, and the position in the height direction of the holding container 3 mounted on the movable table 6 via the two rail members 7 is the side of the semi-solid metal slurry production apparatus 1. Then, it becomes the height which receives the molten metal which flows down in the lower end of 1 A of slant cooling bodies, and while being adjusted so that the bottom part may be located above the gate part on the shaping | molding apparatus 2 side, it is required for a metal molded object One holding container 3 when a quantity of molten metal is held and a movable table 6 on which it is mounted are supported.

なお、この実施の形態にかかるレオキャスト設備では、金型を装着した成形装置２は、パンチ２Ａと、金型装着台２Ｂと、型締め２Ｃなどを有する溶湯鍛造装置とした。溶湯鍛造装置の湯口部は、パンチ２Ａの下方に位置している。この実施の形態のレオキャスト設備に用いた半凝固金属スラリー製造装置１と、溶湯鍛造装置は、従来から用いられている装置である。   In the rheocast equipment according to this embodiment, the molding apparatus 2 on which the mold is mounted is a molten forging apparatus having a punch 2A, a mold mounting base 2B, a mold clamping 2C, and the like. The gate of the molten metal forging device is located below the punch 2A. The semi-solid metal slurry production apparatus 1 and the molten metal forging apparatus used in the rheocast equipment of this embodiment are apparatuses conventionally used.

本発明のレオキャスト設備に用いる保持容器３は、図３に示すように、切り欠き部を形成した固定蓋３Ａと、その切り欠き部を塞ぐスライド蓋３Ｂとで開口部の蓋ができることが好ましい。このようにすれば、半凝固金属スラリー製造装置１側の斜冷却体１Ａの下端にて流下する溶湯を保持容器３で受けた後、固定蓋３Ａの切り欠き部をスライド蓋３Ｂをスライドさせて塞ぐことで、大気と容器内部の溶湯との接触を防ぐことができ、溶湯保持中の酸化を抑制できる。なお、保持容器３の内層３Ｃは、従来と同様に耐火物製とした。   As shown in FIG. 3, the holding container 3 used in the rheocasting equipment of the present invention preferably has an opening lid formed by a fixed lid 3 </ b> A in which a cutout portion is formed and a slide lid 3 </ b> B that closes the cutout portion. . In this way, after the molten metal flowing down at the lower end of the inclined cooling body 1A on the semi-solid metal slurry production apparatus 1 side is received by the holding container 3, the slide lid 3B is slid by sliding the cutout portion of the fixed lid 3A. By closing, contact between the atmosphere and the molten metal inside the container can be prevented, and oxidation during holding of the molten metal can be suppressed. The inner layer 3C of the holding container 3 is made of a refractory material as in the conventional case.

また、本発明のレオキャスト設備に用いる保持容器３は、切り欠き部を形成した固定蓋３Ａと、底部の流出口を塞ぐ棒状ストッパー４とを有し、固定蓋３Ａに棒状ストッパー４が上下動できるガイド孔を設けてなり、固定蓋３Ａのガイド孔に挿入した棒状ストッパー４で底部の流出口を塞いだものとするのがさらに好ましい（図１参照）。
このような保持容器３を具備した場合、図１に示した、金型を装着した成形装置２に半凝固金属スラリーを供給するに際し、固定蓋３Ａのガイド孔に挿入した棒状ストッパー４を引き上げるだけで、半凝固金属スラリーを成形装置２の金型内、容易にかつ安定して供給することができる。 Further, the holding container 3 used in the rheocasting equipment of the present invention has a fixed lid 3A having a notch and a rod-like stopper 4 that closes the outlet at the bottom, and the rod-like stopper 4 moves up and down on the fixed lid 3A. More preferably, a guide hole is provided, and the outlet at the bottom is closed with a rod-like stopper 4 inserted into the guide hole of the fixed lid 3A (see FIG. 1).
When such a holding container 3 is provided, the rod-like stopper 4 inserted into the guide hole of the fixed lid 3A is simply pulled up when supplying the semi-solid metal slurry to the molding apparatus 2 equipped with the mold shown in FIG. Thus, the semi-solid metal slurry can be supplied easily and stably in the mold of the molding apparatus 2.

以上説明した実施の形態にかかるレオキャスト設備の動作について次に説明する。まず、移動台６に搭載された保持容器３の位置を、半凝固金属スラリー製造装置１の傾斜冷却体１Ａの下端から流下する溶湯を受ける位置にしておく。その位置で、金型成形体に要する溶湯を保持容器３で受湯する。受湯後、移動台６を図１中の右方へ向かって移動距離Ｌだけ移動させる。移動台６が図１中に示す成形装置２の湯口部の上方近傍で止まる。その位置で棒状ストッパー４を引き上げると容器底部の流出口より半凝固金属スラリーが自重により流出し、傾斜連結管５を経て、成形装置の金型内へ供給される。半凝固金属スラリーの供給が終了した後、移動台６を図１中、左方へ向かって移動距離Ｌだけ移動させる。それと同時に、成形装置２で金型成形体の成形を行う。移動台６に搭載された保持容器３が、最初の位置に戻ったところで、１サイクルが終了する。これを繰り返すことで、結晶粒がほぼ球状でマクロ偏析や収縮巣が少なく、品質が一定した金属成形体を得ることができる。   Next, the operation of the rheocast facility according to the embodiment described above will be described. First, the position of the holding container 3 mounted on the moving table 6 is set to a position for receiving the molten metal flowing down from the lower end of the inclined cooling body 1A of the semi-solid metal slurry production apparatus 1. At that position, the molten metal required for the mold body is received by the holding container 3. After the hot water is received, the moving table 6 is moved by a moving distance L toward the right in FIG. The moving table 6 stops near the upper part of the gate of the molding apparatus 2 shown in FIG. When the bar-like stopper 4 is pulled up at that position, the semi-solid metal slurry flows out of the container at its bottom by its own weight and is supplied into the mold of the molding apparatus through the inclined connecting pipe 5. After the supply of the semi-solid metal slurry is completed, the moving table 6 is moved by a moving distance L toward the left in FIG. At the same time, a molding body is molded by the molding apparatus 2. When the holding container 3 mounted on the movable table 6 returns to the initial position, one cycle is completed. By repeating this, it is possible to obtain a metal molded body having almost constant crystal grains, less macro segregation and shrinkage, and constant quality.
