では耐摩耗性が低い欠点がある。As is well known, the bed 1 of a machine tool is often made of cast iron-based material. In other words, the 5JJ iron system has the following advantages: it can be manufactured into a relatively easy-to-integrate structure even if it is complex, it has good workability and reduces finishing costs, and it has significantly higher A corrosion resistance than steel materials. Therefore, it is used in the body of machine tools. On the other hand, cast guide surfaces have the disadvantage of low wear resistance when used as is.

記ベツド１が倒置する形で鋳込まれる。In order to provide wear resistance to the guide surface and smooth sliding movement, a guide rail 2 such as a copper strip (850C in this example) made of a different material from the bed 1 is often attached to the guide surface. bed 1. The guide rail 2, whose cross section is shown in FIG. 2 of a casting mold for forming an integral structure with the guide rail 2, is made in advance by a separate process such as cutting. The flask 10 is filled with molding sand 11. The bed 1 is cast in the molding sand 11 in an inverted manner.

It is a well-known thermite agent to which i, V, Mo, Ni, etc. are added. Since the reaction temperature is 1200°C, the reaction occurs at the temperature of the hot water during gj production. However, the thermite agent 26 is not necessarily indispensable, as will be described later.
第４図に示す断面図は、第２図の他の部分の断面図であ

てられている状態を示している。The cross-sectional view shown in FIG. 4 is a cross-sectional view of another part of FIG. 2, and shows a state in which the pad 30 is applied between the guide rail and the molding sand 11.
鋳造時にガイドレール２の曲がりを防ぐものである。当
て金３０の下端には、湯を流す貫通穴３１が形成してあ

（」九Ｉ吏
前記の構成で以下、本発明の溶着鋳造法を説明する。湯
口１４から溶湯、本例ではＦｅ１２の溶湯を注ぎ込む。(9I) The welding casting method of the present invention will be described below with the above configuration. Molten metal, in this example Fe12, is poured from the sprue 14.
湯の温度は、第２の鋳型へ注ぎ込まれる温度より低温度

れた湯は、ガイドレール２の下方の周囲を包むように流
れる。The temperature of the hot water is lower than the temperature at which it is poured into the second mold. , the poured hot water flows through the vertical runner channel 15. It flows through weir 16 and into first mold 12 . The hot water that has flowed into the first mold 12 flows so as to surround the lower part of the guide rail 2.
この状態で第１の鋳型１２内の溶湯が自然冷却するのを
待ち、第１の鋳型の湯を固める。第１の鋳型１２に流入
した湯の熱量は、ガイドレール２を温める。In this state, the molten metal in the first mold 12 is allowed to naturally cool down, and then the molten metal in the first mold is solidified. The amount of heat of the hot water flowing into the first mold 12 warms the guide rail 2.

線の状態のようにＡ。When the first mold hardens, in this example, after several minutes, the lower periphery of the guide rail 2 is held and fixed, so that it has rigidity against bending. When left in a natural bent state, the guide rail 2 of this example will be in the state A as shown by the chain line in FIG.

変形する。Bend like B and C. In this embodiment, if hot water is poured into the second table, the heat of the hot water will enter the guide rail 2 and heat the surface of the guide rail 2, causing only the portion near the surface to rapidly expand thermally. , it expands unevenly and deforms as shown by the chain line.
したがって、前記第１の鋳型１２を設けたものである。Therefore, the first mold 12 is provided.
第１の鋳型１２の注入して数分後（本例では１〜５分後
）、湯口１７から湯を注ぎこむ。Several minutes after pouring into the first mold 12 (1 to 5 minutes in this example), hot water is poured from the sprue 17.

止される。This bending occurs due to the difference in expansion and contraction of the guide rail 2 due to thermal expansion. However, when the hot water poured into the first mold 12 cools and hardens, the guide rail 2 is firmly held and fixed by the cast metal of the first mold and the pad 30. bending is prevented.

ツト剤２６は、必ずしも必要ではなく、配置しなくても
接合はできる。Therefore, the molten metal in the guide rail 2 and the convex portion 27 in the second mold does not cool down easily, so that the molten metal and the metal between the guide rail 2 are more fused together. However, the thermite agent 26 of this embodiment is not necessarily necessary, and bonding can be performed even if it is not provided.

を設けた例である。"Other Embodiments" As can be understood from the above description, the gist of the present invention is to join dissimilar metals by a casting method, and the present invention is applicable to the joining of the machine tool bed and guide rail 2 of the above embodiments. There are no limitations, but as long as it joins dissimilar metals,
Any object may be joined. The casting of the first mold described above may be made of the same material as the casting that is poured into the second mold, or it may be made of any other material as long as it is relatively low-temperature and does not deform the guide rail 2. good. In the embodiment shown in the seventh country, a preheating port 10 is used instead of the thermite agent 26.
This is an example where .

２には、栓４１を介して加熱口４０が形成されている。It is desirable that a plug 41 made of iron or sand is provided at the back of the preheating port 40, into which heat is sent by flame radiation or electric resistance heating means, so that it does not come into direct contact with the cast metal. The examples shown in FIGS. 8(a) and 8(b) show other embodiments of the heating means. A runner 44 is formed in 1ζ of the guide rail 2, and a plurality of support parts 43 are provided so as to communicate with the runner 44. The support portion 43 is formed to wrap around the guide rail 2 from below. Heating section 42 between support section 43

る。FIG. 9 shows another embodiment of a method for preventing deformation of metal parts during welding. Deformation is prevented by applying a partial load to the metal part 2 with a casting dent or the like and embedding the dent in a sand mold to prevent deformation. It is relatively easy to handle because it only involves placing the keren on the metal parts.
