Description
本発明は、未注湯の鋳型に溶湯を注湯する傾動式注湯装置に関する。 The present invention relates to a tilting type pouring device that pours molten metal into a mold for non-pouring.
従来、鋳型に溶湯を注湯する注湯工程においては、溶解炉で溶解した高温の溶湯を取鍋に移し、その取鍋を注湯場まで搬送し、鋳型に注湯を行う方法が知られている。 Conventionally, in the pouring process of pouring molten metal into the mold, a method of transferring the hot molten metal melted in the melting furnace to the ladle, transporting the ladle to the pouring station, and pouring the mold into the mold is known. ing.
この場合、溶解炉と注湯場はそれぞれ独立した場所に設置され、取鍋は搬送台車、フォークリフト、クレーン、ホイストモノレール等の各種の搬送装置で搬送し、注湯場においては取鍋をクレーンやホイストで吊り上げて作業者が手作業で注湯を行うことが一般的である。最近では、作業者による注湯作業を自動注湯機で行う方法も多く採用されるようになっている。 In this case, the melting furnace and the pouring station are installed in independent places, and the ladle is transported by various transport devices such as a transport carriage, forklift, crane, hoist monorail, etc. It is common for an operator to pour hot water manually by lifting it with a hoist. Recently, a method of performing pouring work by an operator using an automatic pouring machine has been widely adopted.
例えば特許文献１では、溶湯は保持炉から取鍋へ給湯され、取鍋が鋳型へ注湯を行っている。ここで、注湯は自動注湯とされている。 For example, in Patent Document 1, molten metal is supplied from a holding furnace to a ladle, and the ladle pours molten metal into a mold. Here, the pouring is an automatic pouring.
また、特許文献２および特許文献３では、扇形の取鍋を搬送台車により搬送し、自動注湯を行っている。 Moreover, in patent document 2 and patent document 3, a sector-shaped ladle is conveyed with a conveyance trolley and automatic pouring is performed.
このように、溶解炉または保持炉から溶湯を運搬容器である取鍋に移し替え、注湯場へ搬送し注湯を行うと、金属材料を溶解してから注湯するまでに時間がかかり、高温に溶解した溶湯の温度が低下し鋳物不良の原因となるという問題があった。 In this way, when the molten metal is transferred from the melting furnace or holding furnace to the ladle that is the transport container, and transported to the pouring station and poured, it takes time to melt the metal material and then pour, There was a problem that the temperature of the molten metal melted at a high temperature was lowered, causing casting defects.
また、高温の溶湯を取鍋で搬送すると、搬送過程で発煙し、作業環境を損ねるだけでなく、溶湯のこぼれや飛散による火災や爆発事故の危険性が高いという問題もあった。 In addition, when hot molten metal is transported in a ladle, not only does it produce smoke during the transport process, and the working environment is impaired, but there is also a problem that there is a high risk of fire and explosion accidents due to spilling and scattering of molten metal.
本発明は以上の事情に鑑みてなされたもので、その目的は、溶解炉または保持炉から溶湯を取鍋によって搬送する工程をなくし、作業効率および安全性を高めるとともに、鋳型への注湯を精度よく行うことである。 The present invention has been made in view of the above circumstances, and its purpose is to eliminate the step of transporting molten metal from a melting furnace or holding furnace by a ladle, to improve work efficiency and safety, and to pour molten metal into a mold. This is done with high accuracy.
上記の目的を達成するために本発明は、溶融金属を生成する溶解炉を傾動させて該溶解炉から鋳型に注湯を行う注湯装置であって、前記溶解炉の出湯口先端の側面断面形状が円弧状を成し、該円弧を形成する円の中心を前記溶解炉の傾動中心とする傾動式注湯装置を提供する。このような注湯装置とすることにより、溶解炉から溶湯を取鍋によって搬送する工程がなくなり、作業効率、作業環境、および安全性が向上し、なお且つ精度良く注湯を行うことができる。 In order to achieve the above object, the present invention provides a pouring device that tilts a melting furnace for generating molten metal to pour molten metal from the melting furnace to a mold, and includes a side cross-sectional view at a tip of a pouring gate of the melting furnace Provided is a tilting type pouring device having a circular arc shape and having the center of a circle forming the circular arc as the tilting center of the melting furnace. By setting it as such a pouring apparatus, the process which takes a molten metal from a melting furnace with a ladle is lose | eliminated, work efficiency, work environment, and safety improve, and also it can pour with high precision.
また、本発明の前記注湯装置は、前記溶解炉の炉壁の側面断面が前記円弧を形成する円の接線を成すように形成された傾動式注湯装置としても良い。このような注湯装置とすることにより、注湯精度をさらに向上させることができる。 Moreover, the said pouring apparatus of this invention is good also as a tilting type pouring apparatus formed so that the side surface cross section of the furnace wall of the said melting furnace might form the tangent of the circle | round | yen which forms the said circular arc. By using such a pouring device, the pouring accuracy can be further improved.
以下、本発明の実施の形態を図面に基づいて詳細に説明する。図１に示すように、本発明の注湯装置は、溶解炉１と、溶解炉１に固着されたフレーム６にピストンロッドの先端が装着されたシリンダー２と、傾動中心軸４とからなる。傾動中心軸４は、側面断面形状が円弧状を成している前記溶解炉１の出湯口３を、その円弧を形成する円の中心で図１の紙面の垂直方向に貫通するように設けられている。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the pouring apparatus of the present invention includes a melting furnace 1, a cylinder 2 in which a tip of a piston rod is attached to a frame 6 fixed to the melting furnace 1, and a tilting central shaft 4. The tilting central shaft 4 is provided so as to penetrate the hot water outlet 3 of the melting furnace 1 whose side sectional shape forms an arc shape in the direction perpendicular to the paper surface of FIG. 1 at the center of the circle forming the arc. ing.
図１においては、本発明の注湯装置は溶解炉１で金属材料を溶解中である。溶解が終了した後、図２に示すように、鋳型搬送装置５により鋳型Ｍを溶解炉１前の注湯位置に搬送し、シリンダー２を伸長することにより、溶解炉１を傾動中心軸４を中心に傾動させ注湯を行う。 In FIG. 1, the pouring apparatus of the present invention is melting a metal material in a melting furnace 1. After the completion of melting, as shown in FIG. 2, the mold M is conveyed to the pouring position in front of the melting furnace 1 by the mold conveying device 5, and the cylinder 2 is extended so that the melting furnace 1 is tilted around the central axis 4. Tilt to the center and pour hot water.
次に、図３、図４および図５に基づいて出湯口３の形状について説明する。図３は溶解炉１の平面図であり、図４は図３のＡ−Ａ矢視図であり、図５は図４の出湯口部分の拡大図である。なお、図６は本発明の溶解炉の出湯口形状を示す斜視図である。 Next, the shape of the tap 3 will be described with reference to FIGS. 3, 4 and 5. 3 is a plan view of the melting furnace 1, FIG. 4 is a view taken along the line AA of FIG. 3, and FIG. 5 is an enlarged view of the outlet portion of FIG. FIG. 6 is a perspective view showing the shape of the outlet of the melting furnace of the present invention.
図５に示すように、溶解炉１の出湯口３は、その先端の断面形状が円弧Ｓ（実線部）を成すようにされている。円弧Ｓを形成する円Ｃ（図５において、点線で示す。）の中心Ｏを溶解炉１の傾動中心としていることは、先述の通りである。これにより、注湯流線を一定位置に安定させることができ、取鍋に比べて大型なため注湯精度を維持しにくい溶解炉による注湯であっても、精度の良い注湯を行うことができる。 As shown in FIG. 5, the outlet 3 of the melting furnace 1 is configured such that the cross-sectional shape of the tip thereof forms an arc S (solid line portion). As described above, the center O of the circle C forming the arc S (indicated by a dotted line in FIG. 5) is the tilting center of the melting furnace 1. As a result, the pouring streamline can be stabilized at a certain position, and even when pouring with a melting furnace that is difficult to maintain the pouring accuracy because it is larger than the ladle, it is possible to perform pouring with high accuracy. Can do.
なお本実施例では、図５に示すように、溶解炉１の炉壁７は円Ｃの接線となるように形成されている（即ち、図５に示すように円Ｃの半径と炉壁７は直角を成す）。これにより、注湯流線がさらに安定し、注湯精度をさらに向上させることができる。 In this embodiment, as shown in FIG. 5, the furnace wall 7 of the melting furnace 1 is formed to be tangent to the circle C (that is, the radius of the circle C and the furnace wall 7 as shown in FIG. 5). Make a right angle). Thereby, the pouring streamline is further stabilized and the pouring accuracy can be further improved.
図７から図９は、本実施例の注湯装置による注湯の様子を表している。図７−９に示すように、溶解炉１を傾動させることにより溶湯８を鋳型Ｍに対して注湯しているが、出湯口の先端の側面断面形状を円弧状とし、その円弧を形成する円の中心を傾動中心とすることにより、また溶解炉１の炉壁７が前記円の接線となるようにするにより、注湯流線が安定し、安定した注湯を行えていることが分かる。 7 to 9 show the state of pouring by the pouring device of this embodiment. As shown in FIG. 7-9, the molten metal 8 is poured into the mold M by tilting the melting furnace 1, but the side cross-sectional shape at the tip of the pouring gate is made into an arc shape, and the arc is formed. By making the center of the circle the tilting center and making the furnace wall 7 of the melting furnace 1 tangent to the circle, it can be seen that the pouring stream line is stable and stable pouring can be performed. .
以上の通り、本発明は、溶解炉から取鍋を介さず直接注湯することにより、溶湯の搬送に起因する作業環境の悪化や災害の危険性をなくすことができ、出湯口の形状を円弧状とすることで、精度の良い注湯を行うことができる。 As described above, the present invention can eliminate the deterioration of the work environment and the risk of disaster caused by the transport of the molten metal by pouring directly from the melting furnace without using the ladle. By using the arc shape, it is possible to perform pouring with high accuracy.
以上、本発明による代表的実施例について説明したが、本発明は必ずしもこれに限定されるものではなく、当業者であれば、添付した特許請求の範囲を逸脱することなく、種々の代替実施例及び改変例を見出すことは可能である。 While typical embodiments of the present invention have been described above, the present invention is not necessarily limited thereto, and various alternative embodiments can be made by those skilled in the art without departing from the scope of the appended claims. And it is possible to find modifications.
