ルギを照射してこれを加熱溶融させ、凝固に伴つ
てチル化させる加工を行なうことがある。 For example, in cast iron products such as gears and engine cylinder heads, the hardness is increased at the periphery of the boss and the nozzle fitting hole (where a pair of surfaces intersect at right angles to form a corner). In order to withstand abrasion and compressive force, these edges can be heated and melted by irradiating high-density energy such as a laser, high-temperature gas, or electron beam, and then chilled as they solidify. be.

されている。 When such remelting and chilling processing is performed, the intermediate cast iron product to be subjected to this processing is constructed, for example, as shown in FIG. 1 (this shows the case where the final product is a gear). In Fig. 1, a through hole 2 which becomes a boss part is bored in an intermediate cast iron product (only a part is shown) 1 that will eventually become a gear, and a portion of the peripheral edge 3 of the through hole 2 to be chilled is A chamfer 6 is cut.

突出する盛り上り部７がそれぞれ形成される。 However, when the chilled processing peripheral edge 3 of such a product 1 is heated and melted and subjected to chilled processing,
Since the molten part swells due to surface tension and solidifies as it is, as shown in FIG. are formed respectively.
このため、従来はこの盛り上り部７を機械加工

した点にある。 The present invention has been developed in view of the above points, and is a cast iron product for remelting and chilling processing that can prevent the occurrence of raised portions on the machined surface due to remelting and chilling and omit post-processing. with the purpose of providing
The feature lies in that each stepped portion is cut into the inner circumferential surface and end surface forming the periphery, each having a dimension that takes into account the swelling caused by remelting.
以下、図面につき本考案の一実施例を詳細に説
明する。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

It is a diagram.

る。 This intermediate product 11 for remelting and chilling processing is integrally molded from cast iron so as to finally form a gear, and has a through hole 12 formed therein which will eventually become a boss portion. A circumferential surface step portion 16 and an end surface step portion 17 are formed on the inner circumferential surface 14 and end surface 15 of the through-hole peripheral edge 13 as a pair of surfaces forming a corner, respectively, and the step portions 16 and 17 are Dimension D 1
and D 2 are each set in advance to values that take into account the swelling caused by remelting during chilling processing.

るので、周縁１３には、第５図に示すように面取
り加工を施した断面形状が作り出される。 When the periphery 13 of the through-hole 12 of the product 11 having the above structure is heated by irradiating high-density energy such as a laser, high-temperature gas, or electron beam, and melts the vicinity of the periphery 13, the surface tension in the molten part increases. When this occurs, the peripheral edge 13 has step portions 16 and 17 with predetermined dimensions, so the peripheral edge 13 has a chamfered cross-sectional shape as shown in FIG. produced.
すなわち、溶融時の表面張力に伴う盛り上りは
段差部１６，１７で吸収されるため、第２図に示
したような盛り上り部７は、本実施例においては
形成されることがない。 That is, since the bulge caused by the surface tension during melting is absorbed by the step portions 16 and 17, the bulge portion 7 as shown in FIG. 2 is not formed in this example.
したがつて、前記中間製品１１にチル化加工を
施して得られた歯車におけるボス部のチル化加工
周縁についての切削仕上加工は省略化することが
でき、生産性が向上される。また、チル化加工を
施工された部分について、硬さが増し、摩耗、圧
縮力に耐えるようになることはいうまでもない。 Therefore, cutting and finishing work on the chilled peripheral edge of the boss portion of the gear obtained by subjecting the intermediate product 11 to the chilling process can be omitted, and productivity is improved. It goes without saying that the parts that have been subjected to the chilling process will have increased hardness and will be able to withstand abrasion and compressive force.
なお、最終製品が歯車である場合につき説明し
たが、本考案はこれに限らず、あらゆる製品に適
用することができる。 Although the case where the final product is a gear has been described, the present invention is not limited to this and can be applied to any product.
以上の説明より明らかなように、本考案によれ
