Description
本発明は、ワークを塑性変形して転造加工する転造加工装置に関する。
The present invention relates to a threading machine that plastically deforms a work to perform threading.
例えば特許文献１には、高硬度の材料からなるボルトや雄ネジを塑性変形することによって加工する加工装置が開示されている。
For example, Patent Document 1 discloses a processing apparatus for processing a bolt or a male screw made of a high hardness material by plastically deforming it.
かかる構成にあっては、ダイスに亀裂や局部破壊が生じにくい構成を採用しており、ダイスの長寿命化を図っている。
In such a configuration, a configuration that is less likely to cause cracks or local destruction in the die is adopted to extend the life of the die.
また、特に近年、自動車等の軽量化が進んでおり、それらに用いられるボルトとしては、硬度が高い熱処理ボルトの需要が増加している。
In recent years, the weight of automobiles and the like has been reduced, and the demand for heat-treated bolts with high hardness is increasing as bolts used for them.
しかしながら、こうした高硬度のボルトを従来のダイスで製造すると、ダイスにチッピング（欠け）が発生してしまったり、加工歯が変形してしまったりする不具合が早期に発生するため、ダイスの寿命が非常に短くなるという問題が生じる。
However, if such high-hardness bolts are manufactured with conventional dies, the dies will have a very long life because chipping (chips) will occur in the dies and problems such as deformation of the processed teeth will occur at an early stage. The problem of shortening occurs.
本発明は、高硬度の母材を塑性変形加工してもダイスを長期にわたって使用できる転造加工装置を提供することを目的とする。
An object of the present invention is to provide a threading processing apparatus capable of using a die for a long period of time even if a base material having a high hardness is plastically deformed.
本発明は、ワークを少なくとも一対のダイスによって挟圧して塑性変形させる転造加工装置であって、基台と、前記一対のダイスと、を備え、前記基台に前記一対のダイスが取り付けられて、前記基台に前記一対のダイスが保持されており、前記一対のダイスのうち、少なくとも一方には、前記ワークを挟圧する方向である挟圧方向に交わる第一の面が形成されており、前記基台には、前記一対のダイスが保持された保持状態で前記第一の面に対向する第二の面が形成されており、前記保持状態で、第一の面と前記第二の面との間には、イソシアネート成分とポリアミン成分とを含む樹脂からなるシート部が介在してなり、前記挟圧方向に交わる方向に沿って一対のダイスが互いに相対移動することを特徴とする転造加工装置である。
The present invention is a threading apparatus for sandwiching and plastically deforming a work with at least a pair of dies, comprising a base and the pair of dies, and the pair of dies are attached to the base. The pair of dies are held on the base, and at least one of the pair of dies is formed with a first surface intersecting in the pressing direction, which is the direction in which the work is pressed. A second surface facing the first surface is formed on the base in a holding state in which the pair of dice are held, and in the holding state, the first surface and the second surface are formed. A sheet portion made of a resin containing an isocyanate component and a polyamine component is interposed between the two, and the pair of dies move relative to each other along the direction of intersection in the pressing direction. It is a processing device.
かかる構成にあっては、ボルト等のワークを転造加工するにあたってダイスにかかる大きな圧をイソシアネート成分とポリアミン成分とを含む樹脂からなる、いわゆるポリウレア樹脂のシート部が受けることによって加工時に発生する衝撃を吸収する。具体的には、ポリウレア樹脂は耐衝撃性に優れ、ダイスにかかる圧を好適に分散してダイスのチッピング（欠け）を抑制する。
In such a configuration, an impact generated during processing is generated when a so-called polyurea resin sheet portion made of a resin containing an isocyanate component and a polyamine component receives a large pressure applied to a die when a workpiece such as a bolt is threaded. To absorb. Specifically, the polyurea resin has excellent impact resistance and preferably disperses the pressure applied to the die to suppress chipping of the die.
ここで、転造加工における一対のダイスにあっては、ワークを挟圧する方向に多大な負荷が付与された状態で固定側ダイスに対して移動側ダイスが所定の移動方向に沿って往復動する。このため、上述のシート部には、ワークを挟圧することで生ずる当該シート部の厚み方向に沿った負荷に対して衝撃吸収効果を発揮すると共に、ダイスの移動に伴って生ずる当該移動方向に沿った負荷に対しても衝撃吸収効果を発揮するものと推定される。したがって、上述した所要の位置にシート部が配置されることで、転造時に発生するダイスに付与される複数種の負荷が総合的に緩和されて、転造ダイスの寿命が向上することとなる。
Here, in the case of a pair of dies in the rolling process, the moving side dies reciprocate along a predetermined moving direction with respect to the fixed side dies in a state where a large load is applied in the direction of sandwiching the work. .. For this reason, the above-mentioned sheet portion exerts a shock absorbing effect against a load along the thickness direction of the sheet portion generated by sandwiching the work, and also exhibits a shock absorbing effect along the moving direction generated by the movement of the die. It is presumed that it exerts a shock absorbing effect even with a heavy load. Therefore, by arranging the seat portion at the required position described above, the load applied to the dies generated at the time of rolling is comprehensively alleviated, and the life of the rolled dies is improved. ..
さらに、前記シート部のシート厚が２ｍｍ以上４ｍｍ以下である構成が提案される。
Further, a configuration is proposed in which the sheet thickness of the sheet portion is 2 mm or more and 4 mm or less.
かかる構成とすることにより、前記シート部のシート厚を適切なものとすることができる。例えば、シート部のシート厚が２ｍｍに満たないと、ダイスにかかる負荷を十分に緩和することができず、ダイスの長寿命化を図ることが困難となる。また、シート部のシート厚が４ｍｍを越えると、ワークに対して転造圧を十分に加えることができず、ねじ山が十分に立ち上がらなくなり、加工精度が低下してしまう。
With such a configuration, the sheet thickness of the sheet portion can be made appropriate. For example, if the sheet thickness of the sheet portion is less than 2 mm, the load applied to the die cannot be sufficiently relaxed, and it becomes difficult to extend the life of the die. Further, if the sheet thickness of the sheet portion exceeds 4 mm, the rolling pressure cannot be sufficiently applied to the work, the screw thread does not rise sufficiently, and the processing accuracy is lowered.
本発明は、ダイスの寿命を長くすることができる優れた効果がある。
The present invention has an excellent effect of extending the life of the die.
以下、本発明の転造加工装置を具体化した実施例を詳細に説明する。なお、本発明は、下記に示す実施例に限定されることはなく、適宜設計変更が可能である。
Hereinafter, an embodiment embodying the rolling processing apparatus of the present invention will be described in detail. The present invention is not limited to the examples shown below, and the design can be changed as appropriate.
図１～図３に示すように、転造加工装置１は、基台１０上に直方体形状を有した一対のダイス１１，２１が取り付けられている。
As shown in FIGS. 1 to 3, the rolling machine 1 has a pair of dies 11 and 21 having a rectangular parallelepiped shape mounted on a base 10.
さらに詳述すると、前記基台１０は、設置面（図示省略）に載置される固定側基台部１０ａと、固定側基台部１０ａに対して片持ち状に支持されて往復移動する移動側基台部１０ｂとを備えている。
More specifically, the base 10 is cantilevered and reciprocates with respect to the fixed side base portion 10a mounted on the installation surface (not shown) and the fixed side base portion 10a. It is provided with a side base portion 10b.
そして、固定側基台部１０ａに固定ダイス１１が取り付けられ、移動側基台部１０ｂに移動ダイス２１が取り付けられる。このとき、各ダイス１１，２１の表面に形成された転造面１２，２２が対向する。
Then, the fixed die 11 is attached to the fixed side base portion 10a, and the moving die 21 is attached to the moving side base portion 10b. At this time, the rolled surfaces 12 and 22 formed on the surfaces of the dies 11 and 21 face each other.
そして、転造加工装置１は、転造面１２，２２間にワークＷを挟持し、ワークＷを挟圧しつつダイス２１を転造面に沿って移動させることでワークＷを転造加工する。
Then, the rolling processing apparatus 1 sandwiches the work W between the rolling surfaces 12 and 22, and moves the die 21 along the rolling surface while sandwiching the work W to perform the rolling processing.
ここで、固定ダイス１１は、固定側基台部１０ａに対して別部材であるライナー４０を介してネジ固定されている。したがって、固定ダイス１１において転造面１２と平行な裏面（第一の面）１３と、ライナー４０の受け面（第二の面）４１とが対向しており、前記裏面１３と前記受け面４１との間にシート形状（薄厚状）のシート部３０が介在されている。
Here, the fixing die 11 is screwed to the fixed side base portion 10a via a liner 40 which is a separate member. Therefore, in the fixed die 11, the back surface (first surface) 13 parallel to the rolled surface 12 and the receiving surface (second surface) 41 of the liner 40 face each other, and the back surface 13 and the receiving surface 41 are opposed to each other. A sheet-shaped (thin-thick) sheet portion 30 is interposed between the and.
シート部３０は、イソシアネート成分とポリアミン成分とを含む樹脂からなる、いわゆるポリウレア樹脂によって構成されている。ポリウレア樹脂は耐衝撃性に優れ、転造加工におけるダイスにかかる圧を好適に分散することができる。ここで、ダイス１１，２１にかかる負荷は、ワークＷを挟圧する挟圧負荷に限られず、移動ダイス２１の移動方向に沿って固定ダイス１１が受ける剪断方向の負荷も含むものである。
The sheet portion 30 is made of a so-called polyurea resin, which is made of a resin containing an isocyanate component and a polyamine component. The polyurea resin has excellent impact resistance and can suitably disperse the pressure applied to the die in the rolling process. Here, the load applied to the dies 11 and 21 is not limited to the pinching load for pinching the work W, but also includes the load in the shearing direction received by the fixed die 11 along the moving direction of the moving die 21.
ここで、ワークであるＭ１０のボルトを転造加工する場合にあって、シート部３０の厚み（シート厚）を変えてダイス１１，２１がチッピング等によって使用不可能となるまでの寿命を調査した結果を図４（ａ）に示す。なお、シート部３０の材料はポリウレア樹脂を用いた。
Here, when the bolt of M10 which is a work is threaded, the life until the dies 11 and 21 become unusable due to chipping or the like by changing the thickness (sheet thickness) of the sheet portion 30 is investigated. The results are shown in FIG. 4 (a). The material of the sheet portion 30 was a polyurea resin.
図４（ａ）における表において、寿命は、ダイス１１，２１のいずれか、又は両方にチッピングが発生するまでに加工したワークの数を示す。
ワーク形状は、加工されたワークの形状を示し、下記のように表現した。
◎は従来形状と変わらず問題なく使用できる。

The work shape indicates the shape of the processed work and is expressed as follows.
◎ can be used without any problem as in the conventional shape.

◎ can be used without any problem as in the conventional shape.
X cannot be used as a product because the bolt ridges cannot be formed accurately.
図４（ａ）に記載される表に示すように、シート部３０を備えることによってダイスの寿命が格段に向上し、特にシート部３０の厚みが２ｍｍ以上になるとダイスの寿命が大幅に延びることがわかる。また、シート部３０の厚みが４ｍｍを越えると、寿命としては延長されるが、加工されたワークが正しく成形されず、製品としての使用に向かなくなってしまう。これはシート部３０の緩衝効果が過剰となり、適正な転造圧が得られないことによるものと思われる。以上のことから、本実施例におけるシート部３０の厚みは２ｍｍ以上４ｍｍ以下が適切であることがわかる。
As shown in the table shown in FIG. 4A, the life of the die is significantly improved by providing the sheet portion 30, and the life of the die is significantly extended especially when the thickness of the sheet portion 30 is 2 mm or more. I understand. Further, if the thickness of the sheet portion 30 exceeds 4 mm, the life is extended, but the processed work is not formed correctly and is not suitable for use as a product. It is considered that this is because the cushioning effect of the sheet portion 30 becomes excessive and an appropriate rolling pressure cannot be obtained. From the above, it can be seen that the thickness of the sheet portion 30 in this embodiment is appropriately 2 mm or more and 4 mm or less.
