Abstract
Description
本発明は、車両・船舶・航空機等の輸送機器、および住宅・ビル・プレハブ等の建造物に備わる金属製の構造体に関する。 The present invention relates to a metal structure provided in a transportation apparatus such as a vehicle, a ship, or an aircraft, and a building such as a house, a building, or a prefab.
従来、金属製の構造体の各部分間は、溶接もしくはロウ付けによって結合されていた。 Conventionally, the parts of a metal structure have been joined by welding or brazing.
従来の技術によれば、鋳造部分を有する金属製の構造体は、細長く、かつ略一定断面の形状である板・管・条等を、鋳造等の方法によって形成され自由度の高い形状をなす部分（以下、鋳造部分）に、溶接もしくはロウ付けにより結合することで、構成されるのが専らである。なお、当該鋳造部分は、結合前既に固体金属となっている。
これは優れた技術で、安価・高強度に製造可能な板・管・条等を、形状自由度の高い鋳造部分を節として組み立てることにより、当該構造体は、所要の形状・強度を得ることが可能となっている。
しかしながら、溶接もしくはロウ付けにより結合する製造方法には、幾つかの問題点がある。
溶接による結合では、結合部分が順次局所的に加熱溶解・冷却されるため、歪み・残留応力等、熱変形に係る問題が複雑な様相を呈するのを免れない。特に、大断面の管を用いる場合、結合部分の溶接長さが長くなり、上記の熱変形に係る問題に加えて、作業時間・製造原価を高める欠点がある。
また、ロウ付けによる結合では、結合部分の形成に、ロウ・即ち母材と異なる金属材料の介在が必須で、構造体全体を同材料とすることは、できない。
さらに、特に自動車・２輪車部品等、比較的小規模の構造体においては、溶接・ロウ付けの作業を複数箇所同時に行うことは稀で、製造に必要な時間は、結合箇所の数に強く依存する。このことは、設計上の大きな制約となる。According to the prior art, a metal structure having a cast part is formed into a shape having a high degree of freedom by forming a plate, pipe, strip, etc., which is elongated and has a substantially constant cross-sectional shape, by a method such as casting. It is exclusively configured by joining to a part (hereinafter referred to as a cast part) by welding or brazing. The cast part is already a solid metal before bonding.
This is an excellent technology, and it is possible to obtain the required shape and strength by assembling plates, pipes, strips, etc. that can be manufactured at low cost and high strength, with the cast part having a high degree of freedom as a node. Is possible.
However, there are some problems in the manufacturing method in which the bonding is performed by welding or brazing.
In the joining by welding, since the joining portion is heated and melted and cooled locally locally, it is inevitable that problems relating to thermal deformation such as strain and residual stress appear complicated. In particular, when a pipe having a large cross section is used, the weld length of the joint portion becomes long, and there is a drawback that the working time and the manufacturing cost are increased in addition to the problems related to the thermal deformation.
Further, in the bonding by brazing, the formation of the bonding portion requires the intervention of a metal material different from the brazing, that is, the base material, and the entire structure cannot be made of the same material.
Furthermore, it is rare that welding and brazing operations are performed at a plurality of locations at the same time, especially in relatively small structures such as automobiles and two-wheeled vehicle parts. Dependent. This is a great design limitation.
以上の課題を解決するため、本発明では以下の製造方法を採用する。
（Ａ）鋳造部分の鋳造に供する鋳型の空洞内部に、板・管・条等の一部を露出し、当該鋳造部分の鋳造時に、鋳型の空洞内部に注がれた溶融金属と当該露出部分が接触することにより、板・管・条等と鋳造部分の結合を行う製造方法。
また特に高い信頼性を要求される場合や、著しく融点の異なる異種金属材料相互の結合のごとく金属組織間の結合に充分な強度が期待できない場合等に有効な補強方法として、本発明では以下の構造も、補足的に提案する。
（Ｂ）（Ａ）に係る製造方法において、当該露出部分に、穴・突起等を設け、当該鋳造部分の固体化により、当該２部分が機械的にも抜去不能となる構造。In order to solve the above problems, the present invention employs the following manufacturing method.
(A) A part of a plate, a pipe, a strip, etc. is exposed inside the mold cavity to be used for casting of the cast part, and the molten metal poured into the mold cavity and the exposed part at the time of casting of the cast part Manufacturing method that joins the cast part with the plate, pipe, strip, etc.
Further, in the present invention, as an effective reinforcing method when high reliability is required or when sufficient strength cannot be expected for bonding between metal structures such as bonding between dissimilar metal materials having significantly different melting points, the present invention provides the following The structure is also proposed as a supplement.
(B) In the manufacturing method according to (A), the exposed portion is provided with holes, protrusions, and the like, and the casting portion is solidified so that the two portions cannot be mechanically removed.
当該製造方法による結合を用いた場合、鋳造作業と結合作業が同時に行われるため、時間的・経済的に有利である。
また、結合部分全体がほぼ同時に加熱・冷却されるため、熱変形による諸問題は、溶接によって結合を行う場合に比較して、極めて単純な様相を呈する。即ち、容易な推測により充分な対策が可能である。
また、ロウ付けによる結合と異なり、結合部分の形成に、ロウ・即ち母材と異なる金属材料の介在が必須ではないので、構造体全体を同材料とすることも可能である。
さらに、特に自動車・２輪車部品等、比較的小規模の構造体においては、溶接・ロウ付けの作業を複数箇所同時に行うことは稀で、製造に必要な時間は、結合箇所の数に強く依存するのに対し、当該製造方法による結合を用いた場合、当該規模の構造体であっても、複数箇所同時の作業が容易に可能であり、製造に必要な時間は、結合箇所の数に依存しないので、設計上の制約とならない。When the joining by the manufacturing method is used, the casting operation and the joining operation are performed simultaneously, which is advantageous in terms of time and economy.
In addition, since the entire joining portion is heated and cooled almost simultaneously, various problems due to thermal deformation appear very simple as compared with the case where joining is performed by welding. That is, a sufficient countermeasure can be taken by easy estimation.
In addition, unlike the joining by brazing, the formation of the joint portion does not require the intervention of a metal material that is different from the brazing, that is, the base material, so that the entire structure can be made of the same material.
Furthermore, it is rare that welding and brazing operations are performed at a plurality of locations at the same time, especially in relatively small structures such as automobiles and two-wheeled vehicle parts. On the other hand, when using the bonding by the manufacturing method, even a structure of the scale can easily work at a plurality of locations simultaneously, and the time required for manufacturing depends on the number of connecting locations. Since it does not depend on it, it does not become a design constraint.
図面に示す金属製の構造体における実施例に基づき、発明の具体例を説明する。容易に推測されるとおり、本発明は、従来溶接・ロウ付け等による結合部分を具備するあらゆる構造体に応用可能である。

図２に、図１に示した鋳造部分を有する金属製の構造体が完成し、当該鋳造部分の鋳造時に、鋳型の空洞内部に注がれた溶融金属と当該露出部分が接触することにより、当該露出部分と鋳造部分の結合された状態を、図１と同一部位の断面図として示した。
図３に、鋳造部分を有する金属製の構造体のうち、当該露出部分に、穴・突起等を設け、当該鋳造部分の固体化により、当該２部分が機械的に抜去不能となる構造を採用した派生形を、図１と同一部位の断面図として示した。

本図に示すように、（１）既に固体金属となっている構成部分が管材の場合、当該空洞部分の内部は（６）中子によって占められ、完成時には空洞となることにより、当該構造体は軽量となる。
当該鋳造作業により、図２に示す如く、（４）空洞部分には溶融金属が充填され、冷却・凝固によって固体化し、（２）鋳造部分となる。このとき、（１）既に固体金属となっている構成部分のうち、（４）空洞部分に露出している部分は、当該溶融金属と直接接触し昇温され、ロウ付けもしくは溶接に近しい状態となり、（２）鋳造部分と固着する。本発明では、この効果により継手を形成する。
なお、さらに図３に示す如く、（１）既に固体金属となっている構成部分のうち、（４）空洞部分に露出している部分に（７）穴もしくは（８）突起を設けることにより、（２）鋳造部分の冷却・凝固の後には機械的にも抜去不能となる構造が、容易に得られる。Specific examples of the invention will be described based on examples of the metal structure shown in the drawings.
