【発明の詳細な説明】 横方向押出によって中空部品に フランジ又はカラーを作る方法 技術分野 本発明は、横方向押出中肉部が支持されている中空部品にフランジ又はカラーを 作る方法に関する。[Detailed description of the invention] Hollow parts by lateral extrusion How to make a flange or collar Technical field The present invention provides a method for attaching a flange or collar to a hollow part in which a laterally extruded mid-wall part is supported. Regarding how to make.
中空部品に形成されたフランジは、ハブ等の場合管のフランジとして数多くの異 なる用途を有する。Flanges formed on hollow parts can be used in many different ways as pipe flanges in the case of hubs, etc. It has several uses.
先行技術 例えば、成形方法として横方向押出がドイツ工業規格８５８３に定義されている 。prior art For example, lateral extrusion is defined as a molding method in German Industrial Standard 8583. .
横方向押出法によるビン又はジャーナルの製造方法および装置が知られており、 これは固定ボディにカラーを横方向押出しすることにも応用される。外側から内 側に半径方向に移動可能なツール要素を用いて歯車を押出すことも知られている 。横方向押出では、材料が一部被加工物の外側から中心に、又、一部被加工物の 中心から外方に流れる。Methods and devices for manufacturing bottles or journals by lateral extrusion are known, This also applies to laterally extruding a collar onto a fixed body. from outside to inside It is also known to extrude gears using tool elements that can be moved radially to the side. . In lateral extrusion, the material is moved partly from the outside of the workpiece to the center, and partly from the outside of the workpiece. Flows outward from the center.
カラーの横方向押出による固い鋼ボディの固定ブロック成形は、雑誌［ドラ−） （Ｄｒａｈｔ） Ｊの１９８４年第３５号１３ページに説明されている。ドイ ツ公告公報第１０８７４３３号は、特にフリーホイール用ブレーキハブのハブボ ディの横方向押出中パンチによる内側支持法を開示している。Fixed block molding of solid steel body by lateral extrusion of collar is magazine [Dollar] (Draht) J, No. 35, 1984, page 13. Doi Publication No. 1087433 specifically applies to hub bolts for freewheel brake hubs. Discloses a method for internal support by punches during lateral extrusion of D.
これまで中空部品のフランジ又はカラーの横方向押出は、皺や重なりがフランジ 形成位置で中空部品内部に常にできるという点で不利であった。かかる重なりを ２側面缶押出および横方向押出の組合せによって回避することが一般的に知られ ている。カラー又はフランジ付中空部品は、缶底に孔を開けることによっても作 ることができる。しかしながら、かかる手順によって得られる中空部品の長さは 、直径に対する長さの工程基準比率（約４以下）に依存し、かくて、即ち、これ までは工程基準の最大長さをもつ中空部品しか作ることができなかった。Up until now, lateral extrusion of flanges or collars on hollow parts has been difficult to avoid due to wrinkles and overlaps on the flange. This is disadvantageous in that it always forms inside the hollow part at the forming location. This overlap It is generally known to be avoided by a combination of two-sided can extrusion and lateral extrusion. ing. Hollow parts with collars or flanges can also be made by drilling holes in the bottom of the can. can be done. However, the length of the hollow part obtained by such a procedure is , depending on the process standard ratio of length to diameter (approximately 4 or less), thus i.e. Until now, it was only possible to make hollow parts with the maximum length specified by the process standard.
発明の説明 本発明の課題は、フランジ又はカラー領域に重なりなしにフランジ又はカラーを 作ることができ、かつ、製造コストが安く、一方ミフランジを備えた中空部品の 長さについて工程基準制限がない、フランジ又はカラー付中空部品の製造方法を 提供することである。Description of the invention The object of the present invention is to fit the flange or collar without overlapping the flange or collar area. can be made, and the production cost is low, while hollow parts with miflanges A method for manufacturing hollow parts with flanges or collars that has no process standard restrictions on length. It is to provide.
前記の形式の方法では、この課題は、塑性的に振舞う媒体によって穴の中で材料 が支持されることによって解決される。In methods of the type described above, this task is achieved by displacing the material in the hole by means of a plastically behaving medium. This is resolved by supporting the issue.
横方向押出中中空部品の塑性内側支持により、横方向に流れる材料を内側に重な り又は皺を作ることなしに外側に向って驚くほど偏向させることができ、フラン ジを単一工程段階で作ることができる。Plastic inner support of hollow parts during lateral extrusion allows the material flowing laterally to overlap inside. It can be surprisingly deflected outward without creating wrinkles or creases, making the flan can be made in a single process step.
制御された可変の材料流れが塑性支持体から生ずる。安価な横方向押出法によっ −Ｃ作られたカラーの重なりをもつ在来法による部品は、あまり重要でない口約 にしか用いることができなかった。A controlled and variable material flow results from the plastic support. by an inexpensive lateral extrusion method. -Conventionally manufactured parts with overlapping colors are of minor importance. It could only be used for.
というのは、前記型なりを、強度計算において考慮することができず、又同時に 重なりが、荷重をかけたとき、クラックの開始個所、および構成部品の破損を意 味していたからである。本発明の方法の好ましい実施例では、塑性的におよび／ 又は弾性的に変形できる材料、例えば、ゴム、プラスチック、軟質金属等が支持 のために用いられる。This is because the above-mentioned shape cannot be taken into account in the strength calculation, and at the same time Overlapping can be a point of initiation for cracks and failure of components when loads are applied. Because I had tasted it. In a preferred embodiment of the method of the invention, plastically and/or or supported by elastically deformable materials such as rubber, plastic, soft metals, etc. used for.
本発明方法のもう１つの実施例によれば、支持のためにガス、好ましくは高圧の ガスが用いられる。According to another embodiment of the method according to the invention, gas, preferably high pressure, is used for the support. Gas is used.
本発明方法の特に好ましい実施例では、支持のために水が用いられる。前記水は １００００バールまでの範囲の圧力で弾性的に振舞う。In a particularly preferred embodiment of the process according to the invention, water is used for support. The water is Behaves elastically at pressures in the range up to 10,000 bar.
本発明方法の結果、回転対称および非回転対称両方のフランジ又はカラーを作る ことができる。As a result of the method of the invention, both rotationally symmetrical and non-rotationally symmetrical flanges or collars are produced. be able to.
支持効果は一部、マルドレルによって得ることができ、塑性材料は平衡および逆 流のため、にフランジの領域でのみ用いられる。The supporting effect can be partly obtained by Mardrel, and the plastic material can be Because of the flow, it is used only in the flange area.
周囲温度および高温いずれにおいてもフォーミングを行うことができる。Forming can be performed at both ambient and elevated temperatures.
本方法は、横方向押出によって成形できるすべての材料について用いることがで き、それ自体が知られたその他の成形方法の一部をなすこともでき、例えば、絞 り方法、膨張方法等と一緒に用いることができる。鋼を、本発明方法によって特 に好ましい仕方で横方向に押出すことができる。This method can be used for all materials that can be formed by lateral extrusion. and may itself form part of other known forming methods, e.g. It can be used together with the expansion method, expansion method, etc. Steel is characterized by the method of the present invention. can be extruded in the transverse direction in a preferred manner.
本発明方法によって初めて、横方向押出によって内側に重なりを形成することな く、又、高価な工程段階を含むことなしに、中空部品にフランジ又はカラーを作 ることができる。For the first time, the method of the present invention eliminates the formation of internal overlaps due to lateral extrusion. Create flanges or collars on hollow parts without involving expensive process steps. can be done.
第１図は、在来方法の製品の断面図である。FIG. 1 is a cross-sectional view of a conventional product.
第２図は、横方向押出中中空部品の内壁に弾性／塑性媒体中で作用する力の加え 状態を示した図である。Figure 2 shows the application of forces acting in an elastic/plastic medium on the inner wall of a hollow part during lateral extrusion. It is a figure showing a state.
発明を実施するための最良の形態 図面と関連して、以下に実施例をさらに詳しく説明する。BEST MODE FOR CARRYING OUT THE INVENTION Embodiments are explained in more detail below in conjunction with the drawings.
ている。本発明方法によれば、カラーの領域に重なりなしに管を作ることができ る（第２図）。ing. According to the method of the present invention, a tube can be made without overlapping in the collar area. (Figure 2).
本発明方法の好ましい実施例によれば、水が高圧で、即ち、１００００バールま での圧力で支持のために管の横方向押出中キャビティ内に圧入される。水は瞬間 の幾何的要求にたえず順応する弾性支持体を提供し、かくして、横方向押出中所 望の材料流れ方向を得ることができる。According to a preferred embodiment of the process according to the invention, the water is supplied at high pressure, i.e. up to 10,000 bar. is forced into the cavity during lateral extrusion of the tube for support with pressure at . water is instant provides an elastic support that continually adapts to the geometrical demands of the A desired material flow direction can be obtained.
横方向押出の終わりにフォーミングおよび水圧を下げて、内側フランジの再生な しに仕上り製品を取り出すことができる。Reduce forming and water pressure at the end of lateral extrusion to avoid regeneration of the inner flange. The finished product can then be removed.
カラーの成形中管の膨張と同時にフォーミングが行なわれる。During the forming of the collar, forming occurs simultaneously with the expansion of the tube.
かくして、第２図では、フォーミング領域６で中空部品５の元の管径を、フォー ミングと平行してがっ、カラー２の製造を伴って、管の最終直径１まで膨張させ ることができる。Thus, in FIG. 2, the original tube diameter of the hollow part 5 is changed in the forming region Parallel to the manufacturing process, the tube is expanded to its final diameter 1, accompanied by the production of collar 2. can be done.
上記の説明、および図面、および特許請求の範囲に開示された本発明の特徴は、 単独で、或いはでたらめに組合せて、本発明の異なる実施例を実現するのに不可 欠である。The features of the invention disclosed in the above description, drawings, and claims include: Indispensable elements used alone or in random combination to realize different embodiments of the present invention. It is lacking.
