Description
【0001】
本発明は、請求項1の前提部分に基づく、同心ハブを有する成形体を製造するための装置に関する。
【0002】
かかる装置で製造された成形体は、多くの利用分野に用途が見つかっている。流動成形法(Druckverfahren)として知られている非切削製造方法は、通常、冷間変形法であり、そして特に、自動車製造の際に例えば変速装置部品として使用されるような大量生産品の合理的且つ経済的な製造を可能にする様々な利点を特徴としている。
【0003】
記載した形式の装置は、例えば、国際公開WO94/20235から既知である。そこでは、同心ハブを備えた成形体が、丸い金属素材、即ち中心穴を有する金属薄板から流動成形により製造される。
【0004】
作業ローラの助けを借りて、丸い素材からの材料は、半径方向の送り込みにより絞り出されてマンドレルの方向に移動させられ、そこでマンドレルに当て付形することによりハブの形にされる。非破壊的変形とも呼ぶことができる材料の移動の過程で、丸い素材の厚さは、ハブの付形に必要な材料の除去に従って減少される。
【0005】
作業ローラは、一方では、丸い素材からの材料の除去を生じさせ、他方では、マンドレルの方向への材料の移動を生じさせるが、従動ローラは、第1に、流動成形中の丸い素材の屈曲を防止し、第2に、マンドレルに対する正確な付形を行う役目を果している。従動ローラは短い間隔で作業ローラに追従する。
【0006】
既知の装置において、作業ローラは、それらの周方向加圧面がマンドレル又は丸い素材の長手方向中心軸線に平行に位置するように形成されていて、該加圧面は、丸い素材と係合状態に至ることのできる流動成形縁と直接に隣り合っている。
【0007】
作業ローラの軸方向及び半径方向の送り込みの際、丸い素材から分離した材料は、加圧面の前で次第に増大して、マンドレルの領域中に移動され、そこで材料は、ハブの高さを制御するストッパに達するまでマンドレルに沿って流動する。
【0008】
しかし、説明した材料の増大の際に、非常に大きな力が加圧面のところに発生し、この力は、作業ローラに作用すると共に、対応の機械要素の対応するサイズ変更を必要とするだけでなく、比較的に強い摩耗に至ることになる。
【0009】
いわばアプセットされた材料は、マンドレルに当接することになる直前までは、マンドレルに平行又はほぼ平行に流動することはないと同時に、その時点の前、それは比較的に厚い***の余地を持つようになることが分かった。
【0010】
従って、この発明の目的は、流動成形中に生ずる負荷が減少するように、記載した形式の装置を形成することである。
【0011】
この目的は、請求項1の特徴を有する装置及び/又は請求項10に基づく方法により達成される。
【0012】
驚いたことに、実質的により小さな***状の材料増大が作業ローラの半径方向送り込みにおいて達成されることが分かった。実際に、作業ローラにより丸い素材から分離された材料は、早い時期に加圧面に沿って流動するので、流動形成のために費やされねばならない力の減少又はより小さな負荷が自然な方法でもたらされる。これは、本発明の有利な開発において10°より小さく、好ましくは3〜5°の傾斜を提供する最適設計の作業ローラと仮定すると、先行技術による流動成形におけるよりも40%ほど小さい。
【0013】
このように予成形されたハブは、作業ローラによりマンドレルに対して実際に直接押し付けられていない。これは、加圧面が長手方向中心軸線と平行に置かれた従動ローラにより行われ、この従動ローラによって、前には若干傾いていた、即ち、朝顔形をしていたハブは、円筒形状になるような方法でマンドレルに押し付けられる。
【0014】
本発明の第1の思想によると、従動ローラは、ハブの端部制限のための突起を有しており、成形中、この突起に対してハブがその自由端面で当接する。
【0015】
ここでマンドレルは、肩部の形のストッパを更に有することができ、これは、ハブの高さを制限すると共に、丸い素材と平行に、加圧ローラの突起と同一平面に位置している。
【0016】
しかし、マンドレルを全体にわたり平滑な軸部で形成することも考えられるので、その場合、従動ローラのみがハブ付形の終端限界を形成する。
【0017】
製造を最適化するために、従動ローラのストッパ形成突起とマンドレルとの間に小さな環状の間隙を残す備えが更になされており、その中に、ハブ付形の間に過剰の材料を通すことができ、この過剰材料は続くハブ機械加工の際に除去される。
【0018】
突起の幅及び肩部の幅は、同じ大きさであることが好ましいが、全体としてはたかだかハブの壁厚に等しい。
【0019】
請求項10の前提部分に基づいて丸い素材からハブ付きの成形体を非切削で製造するための方法において、ハブは初期に、作業ローラにより、その壁をマンドレルの中心軸線に関して外側に斜めに配置させて、朝顔形に成形され、その後、従動ローラにより壁をマンドレルに押圧することによって円筒形の形状にされる。
【0020】
本発明の更なる有利な開発は従属請求項において特徴として記載されている。
【0021】
以下に、本発明の例示的な実施形態が添付図面に基づいて記載されている。
【0022】
図は、同心ハブ12を有する成形体1を製造するための装置を表わしており、この装置は、チャックの形の回転工具プレート2と、作業ローラ4と、従動ローラ7と、マンドレル3とを有している。
【0023】
工具プレート2は、凹部を有していて、その中に、丸い素材11があり、その上にハブ12を作業ローラ4及び従動ローラ7により付形することができ、作業ローラ4は、その端部へと、丸い素材11の中心軸線に関して軸方向及び半径方向に送り込まれることができる。
【0024】
付形のため、最初に、中央に穴のある円板状の素材11は、工具プレート2の中に入れられ、固定して回転される。最初、工具プレート2の上方から突き出ている丸い素材11の材料は、作業ローラ4の加圧縁によりマンドレル3の方向に押し出され、こうして分離した材料は、作業ローラ4の加圧面に当たり支持される。
【0025】
丸い素材11から始まって、加圧面は、図の右側に例示するように、初期の大雑把に言って朝顔形のハブが形成されるように、マンドレル3の長手方向軸線に関して外側に傾斜している。
【0026】
加圧面6の傾斜角は3〜5°が好ましい。
【0027】
従動ローラ7は、丸い素材11の対応する成形表面に当たり支持されて、作業ローラ4の直ぐ後に従う。従動ローラ7もまた、加圧面13を有しており、しかしこれはマンドレル3の中心軸線に平行に位置している。初期に傾斜していたハブ12は、同心の円筒形状のハブ12が創生されるように、この加圧面によりマンドレル3に押し付けられて、それと接合状態になる。
【0028】
従動ローラ7は、丸い素材11から離れる方に向くその一側に突起8を有しており、これは、ハブ12の形成での終端限界を表わすと共に、その高さの寸法を規定する。
【0029】
その意味で、マンドレル3が周方向の肩部9を有し、それが同様に、ハブ12の当接するストッパを形成している。肩部9及び突起8の各ストッパ面は、一つの平面内に位置している。
【0030】
更に図に示すように、環状の間隙10が突起8とマンドレル3との間に形成されており、この間隙内に、過剰の材料がハブ付形中に流入することができるので、ハブ12のすべての点で正確な形成が何ら問題なしに可能である。この過剰は、続いて機械切削により除去することができる。

The invention relates to an apparatus for producing a shaped body with a concentric hub according to the preamble of claim 1.
[0002]
The molded body produced by such an apparatus has found use in many fields of use. The non-cutting manufacturing method known as the fluid forming method (Druckverfahren) is usually the cold deformation method, and in particular the rationality of mass-produced products such as those used in transmissions, for example as transmission parts It is also characterized by various advantages that allow for economical production.
[0003]
A device of the type described is known, for example, from WO 94/20235. There, a compact with a concentric hub is produced by fluid molding from a round metal material, ie a metal sheet with a central hole.
[0004]
With the help of the work roller, the material from the round blank is squeezed out by radial feeding and moved in the direction of the mandrel, where it is formed into a hub by applying it to the mandrel. In the course of material movement, which can also be referred to as non-destructive deformation, the thickness of the round blank is reduced according to the removal of the material required for hub shaping.
[0005]
The work roller, on the one hand, causes the removal of material from the round blank and, on the other hand, the movement of the material in the direction of the mandrel, while the driven roller firstly bends the round blank during fluid molding. Secondly, it plays the role of accurately shaping the mandrel. The driven roller follows the work roller at short intervals.
[0006]
In known devices, the working rollers are formed such that their circumferential pressure surfaces are positioned parallel to the longitudinal central axis of the mandrel or round material, which press surfaces reach engagement with the round material. Directly adjacent to the fluid molded edge that can.
[0007]
During the axial and radial feeding of the work roller, the material separated from the round blank gradually increases in front of the pressing surface and is moved into the mandrel area, where the material controls the height of the hub. Flows along the mandrel until it reaches the stopper.
[0008]
However, during the increase of the material described, a very large force is generated at the pressing surface, which acts on the work roller and only requires a corresponding sizing of the corresponding machine element. Rather, it leads to relatively strong wear.
[0009]
In other words, the upset material does not flow parallel or nearly parallel to the mandrel until just before it comes into contact with the mandrel, but before that point it has room for a relatively thick ridge. I found out that
[0010]
Accordingly, it is an object of the present invention to form an apparatus of the type described so that the load generated during fluid molding is reduced.
[0011]
This object is achieved by a device having the features of claim 1 and / or a method according to claim 10.
[0012]
Surprisingly, it has been found that a substantially smaller raised material increase is achieved in the radial feed of the work roller. In fact, the material separated from the round material by the work roller will flow along the pressure surface at an early stage, resulting in a natural reduction in the force that must be spent for flow formation or a smaller load. It is. This is 40% less than in prior art flow forming, assuming an optimally designed work roller that provides an inclination of less than 10 °, preferably 3-5 °, in an advantageous development of the invention.
[0013]
The hub preformed in this way is not actually pressed directly against the mandrel by the working roller. This is done by a driven roller whose pressing surface is placed parallel to the longitudinal central axis, by which the hub that has been tilted slightly before, ie in the form of a morning glory, becomes cylindrical. It is pressed against the mandrel in such a way.
[0014]
According to the first concept of the present invention, the driven roller has a protrusion for limiting the end of the hub, and the hub abuts against the protrusion at the free end surface during molding.
[0015]
Here, the mandrel can further comprise a stopper in the form of a shoulder, which limits the height of the hub and lies parallel to the round blank and in the same plane as the protrusions of the pressure roller.
[0016]
However, it is also conceivable to form the mandrel with an entirely smooth shaft, in which case only the driven roller forms the end limit of the hub type.
[0017]
In order to optimize manufacturing, there is further provision for leaving a small annular gap between the follower roller stop forming protrusion and the mandrel, in which excess material can be passed between the hub-shaped. This excess material can be removed during subsequent hub machining.
[0018]
The width of the protrusion and the width of the shoulder are preferably the same, but as a whole are at most equal to the wall thickness of the hub.
[0019]
11. A method for non-cutting production of a molded body with a hub from a round blank according to the premise of claim 10, wherein the hub is initially arranged with its working roller obliquely outwardly with respect to the mandrel central axis. Then, it is formed into a morning glory shape, and then formed into a cylindrical shape by pressing the wall against the mandrel by a driven roller.
[0020]
Further advantageous developments of the invention are described as features in the dependent claims.
[0021]
In the following, exemplary embodiments of the invention are described with reference to the accompanying drawings.
[0022]
The figure shows an apparatus for producing a shaped body 1 having a concentric hub 12, which comprises a rotary tool plate 2 in the form of a chuck, a work roller 4, a driven roller 7 and a mandrel 3. Have.
[0023]
The tool plate 2 has a recess, in which a round material 11 is formed, on which a hub 12 can be shaped by a work roller 4 and a driven roller 7, and the work roller 4 has its end. The part can be fed axially and radially with respect to the central axis of the round material 11.
[0024]
Due to the shaping, first, a disk-shaped material 11 having a hole in the center is put in the tool plate 2 and fixedly rotated. Initially, the material of the round material 11 protruding from above the tool plate 2 is pushed out in the direction of the mandrel 3 by the pressure edge of the work roller 4, and the material thus separated hits the pressure surface of the work roller 4 and is supported. .
[0025]
Starting from the round material 11, the pressure surface is inclined outwardly with respect to the longitudinal axis of the mandrel 3 so that a morning glory hub is formed, as illustrated on the right side of the figure. .
[0026]
The inclination angle of the pressing surface 6 is preferably 3 to 5 °.
[0027]
The driven roller 7 is supported by the corresponding molding surface of the round blank 11 and follows immediately after the work roller 4. The driven roller 7 also has a pressure surface 13, but this is located parallel to the central axis of the mandrel 3. The initially tilted hub 12 is pressed against the mandrel 3 by this pressure surface so that a concentric cylindrical hub 12 is created and is joined to it.
[0028]
The driven roller 7 has a protrusion 8 on one side thereof that faces away from the round blank 11, which represents the end limit in the formation of the hub 12 and defines its height dimension.
[0029]
In that sense, the mandrel 3 has a circumferential shoulder 9, which likewise forms a stopper against which the hub 12 abuts. The respective stopper surfaces of the shoulder 9 and the protrusion 8 are located in one plane.
[0030]
As further shown in the figure, an annular gap 10 is formed between the protrusion 8 and the mandrel 3, and excess material can flow into the hub-mounted shape into the gap, so that the hub 12 Accurate formation in all respects is possible without any problems. This excess can subsequently be removed by machine cutting.
