Description
本発明は、金属合金の連続鋳造品又は押出品から、自動車用構成部品を製造する方法に関する。 The present invention relates to a method for producing a component for an automobile from a continuous cast or extruded product of a metal alloy.
特許文献1では、自動車のバルブ駆動装置について開示しており、このロータ及びハウジングは、押出しアルミニウム合金から製造される。この場合、鋼片は、所望の長さに切り落とされ、次いで切断及び研磨工程によって処理される。 Patent Document 1 discloses a valve driving device for an automobile, and the rotor and the housing are manufactured from an extruded aluminum alloy. In this case, the steel slab is cut to the desired length and then processed by a cutting and polishing process.
本発明の目的は、素早くかつコスト効果の高い製造が確実となる製造方法を設計し、配置することである。 The object of the present invention is to design and arrange a manufacturing method that ensures fast and cost-effective manufacturing.
上記目的は、本発明に従って、構成部品素材が、連続鋳造品又は形材或いは押出品又は形材を分割することによって製造され、その構成部品素材が、分割の前又は後の成形工程において鋳型を用いて、その構成部品の要求寸法に較正されることによって達成される。 The above object is achieved in accordance with the present invention in that a component material is produced by dividing a continuous casting or profile or extrudate or profile, and the component material is molded in a molding process before or after the division. And is achieved by calibrating to the required dimensions of the component.
このようにして製造された構成部品素材は、高価な切断又は研磨工程によって処理する必要がない。構成部品素材が鋳型内又は鋳型全体の圧縮操作によって得られるので、成形工程は、極めて素早くかつ簡単にその効果が生じる。 The component material produced in this way does not need to be processed by an expensive cutting or polishing process. Since the component material is obtained by a compression operation in the mold or in the entire mold, the effect of the molding process is very quick and simple.
このため、構成部品素材をその構成部品の仕上り寸法に成形することは、冷間圧縮又は冷間成形工程、温間圧縮又は温間成形工程、或いは熱間圧縮又は熱間成形工程によって達成されることが好ましい。 For this reason, forming the component material into the finished dimensions of the component is accomplished by a cold compression or cold forming process, a warm compression or warm forming process, or a hot compression or hot forming process. It is preferable.
この場合、成形工程は、構成部品が冷たい状態の時にその効果が生じ得る。また、鋳型内の加熱状態の熱膨張を考慮しながら、構成部品素材を成形する手段が講じられる。 In this case, the molding process can be effective when the component is cold. In addition, a means for forming the component material is taken into consideration while taking into account the thermal expansion of the heated state in the mold.
発展形態によれば、さらに、構成部品素材及び/又は鋳型の、少なくとも互いに接触している表面部分を、較正の前に潤滑剤で湿らせることができる。 According to a further development, at least the surface parts of the component material and / or mold that are in contact with each other can be moistened with a lubricant before calibration.
潤滑剤を使用することにより磨耗のない成形操作が確実となるので、構成部品と鋳型との間の冷間溶接現象が防止される。この場合、構成部品及び鋳型は、それぞれ、対応する表面の、冷間溶接現象を助ける、少なくとも重要な領域内が潤滑剤で湿らされる又は覆われる。 The use of a lubricant ensures a wear-free molding operation and prevents cold welding phenomena between the component and the mold. In this case, the component and the mold are each wetted or covered with a lubricant in the corresponding surface, at least in the critical areas that help the cold welding phenomenon.
さらに、使用される潤滑剤は、油、固体潤滑剤、及び/又はプラスチックであることが好ましい。 Furthermore, the lubricant used is preferably an oil, a solid lubricant and / or a plastic.
グリース又は噴霧プラスチック潤滑剤などの固体潤滑剤を使用することにより、冷間溶接現象のない成形工程が実現できる。 By using a solid lubricant such as grease or sprayed plastic lubricant, a molding process without cold welding phenomenon can be realized.
このため、構成部品の寸法が、少なくとも一部分、構成部品素材を製造する工程後に行われる成形工程によって成形されることも好ましい。 For this reason, it is also preferable that the dimensions of the component parts are at least partially molded by a molding process performed after the process of manufacturing the component material.
この場合、成形工程は、切断又は研磨工程より実質的に簡単かつ素早く配置され得る。このようにして成形された構成部品は、必要な許容範囲の大きさを有する。 In this case, the molding process can be arranged substantially easier and faster than the cutting or polishing process. The component molded in this way has the required tolerance size.
最後に、本発明による解決方法の好ましい実施形態によれば、構成部品を、カム軸調節器用のロータとして又はロータハウジングとして設計する手段が講じられる。 Finally, according to a preferred embodiment of the solution according to the invention, measures are taken to design the component as a rotor for the camshaft adjuster or as a rotor housing.
本発明の特に重要な点は、ロータが、中心軸の周囲に均一に分散されるよう配置された4枚の羽根を備えることが好ましいということにある。 A particularly important aspect of the present invention is that the rotor preferably comprises four blades arranged to be evenly distributed around the central axis.
本発明による設計及び配置と関連して、ハウジングが羽根用に4つの窪みを有することが好ましく、これらの窪みが中心軸の周囲に均一に分散されるよう配置されることが好ましい。中心軸に対する窪み内の各羽根の角位置は、操作中に変化する。 In connection with the design and arrangement according to the invention, it is preferred that the housing has four depressions for the vanes, and these depressions are preferably arranged so as to be evenly distributed around the central axis. The angular position of each blade within the recess relative to the central axis changes during operation.
本発明のさらなる利点及び詳細が、頭記の特許請求の範囲及び以下の記述に説明され、図に示されている。 Further advantages and details of the invention are set forth in the appended claims and the following description and illustrated in the figures.
本明細書に示されている構成部品1及び2は、ハウジング1、及び前記ハウジング1によって収容されるロータ2である。この場合、ハウジング1もロータ2も、カム軸(図示せず)と同軸状に又はカム軸の中心軸3と同軸状に配置される。ロータ2及びハウジング1は、この場合、放射状に走る表面1.3、2.3を介して作動連結している。中心軸3に対するロータ2とハウジング1との間の相対角位置は、操作中、調整機構(図示せず)によって変化する。 The components 1 and 2 shown here are a housing 1 and a rotor 2 accommodated by the housing 1. In this case, both the housing 1 and the rotor 2 are arranged coaxially with the cam shaft (not shown) or coaxial with the central axis 3 of the cam shaft. The rotor 2 and the housing 1 are in this case operatively connected via radially running surfaces 1.3, 2.3. The relative angular position between the rotor 2 and the housing 1 with respect to the central axis 3 is changed by an adjustment mechanism (not shown) during operation.
このため、ロータ2は、ロータハウジング2の対応する窪み1.2〜1.2’’’内に配置された4枚の羽根2.2〜2.2’’’を備えるが、対応する窪みを有する別の数の羽根も考えられる。 For this purpose, the rotor 2 comprises four blades 2.2-2.2 ′ ″ arranged in the corresponding recesses 1.2-1.2 ′ ″ of the rotor housing 2, but the corresponding recesses Other numbers of vanes having are also conceivable.
製造工程中の重要な要因は、基本的に、連続鋳造後の鋳型を利用した成形工程により、仕上り寸法に形作られる又は較正される、羽根2.2及び窪み1.2の大きさである。 An important factor during the manufacturing process is basically the size of the vanes 2.2 and the depressions 1.2 that are shaped or calibrated to the finished dimensions by a molding process using a mold after continuous casting.
