Description

【０００１】
【発明の属する技術分野】
本発明は、摩耗やクラック修理のため等に母材の穴部に肉盛りを行う穴部の肉盛り方法および肉盛り装置に関する。
【０００２】
【従来の技術】
機械部品等の穴部の摩耗やクラック修理のために、穴部の内側に肉盛りを行う場合があるが、母材がアルミ合金等においても他の金属と同様に、従来は、ＴＩＧ溶接法（タングステン電極を用いる不活性ガスアーク溶接法）等の溶融溶接により当該穴部の肉盛りを行っていた。
【０００３】
アルミ合金等の軽金属の穴部の修理の際、ＴＩＧ溶接等の溶融溶接による肉盛りを実施すると、かなりの高温になるため、熱によって部品の変形や材料の機械強度低下が発生してしまい、肉盛り不良が生じる場合があった。
この対策として、例えば、図３の（ａ）に示すように、アルミ合金で形成された母材３に空けられた比較的小さな穴部３ａの内側を肉盛りして修理する手段として、母材３の下面側において穴部３ａの開口端を閉塞するように当て板５を当てがい、穴部３ａ内に溶接材４を入れた状態で、モータ等の駆動手段２で摩擦棒１を回転させるとともに、図３に（ｂ）に示すように、穴部３ａ内に圧入させる手段が提案されている。
【０００４】
この手段によれば、高速回転する摩擦棒１と溶接材４との間、もしくは溶接材４と当て板５との間で瞬間的に大きな摩擦熱を発生させるので、塑性化された溶接材４は、摩擦棒１によって塑性流動し、摩擦棒１と母材３との隙間に押し出されて該隙間を埋めるとともに、溶接材４と母材３とが混合、接合し、穴部３ａの内側が肉盛りされる。
このような穴部の肉盛り手段では、母材３の融点まで温度を上昇させず、瞬時に溶接材４を塑性流動させるため、変形や強度低下が抑えられ、穴部３ａの良好な肉盛りが可能となるものである。
【０００５】
【発明が解決しようとする課題】
しかしながら、従来の肉盛り手段では、以下のような課題が残されている。すなわち、穴部の底における塑性流動が小規模なため、底近傍で母材と溶接材との間に接合不良が発生するおそれがあった。また、溶接材が摩擦棒によって押し出される際に、穴部の底で径方向への流れが発生し、この部分で穴部の変形が生じるおそれがあった。さらに、溶接材の流動部と母材とが擦れることによる酸化被膜除去効果が小さくなってしまい、酸化被膜の残留により接合不良等が発生するおそれがあった。
【０００６】
本発明は、前述の課題に鑑みてなされたもので、穴部の底近傍での接合不良および変形等を防止するとともに、酸化被膜の残留を防いで良好な接合を得ることができる穴部の肉盛り方法および肉盛り装置を提供することを目的とする。
【０００７】
【課題を解決するための手段】
本発明は、前記課題を解決するため、以下の構成を採用した。すなわち、請求項１記載の穴部の肉盛り方法では、母材を貫通した穴部の肉盛り方法であって、前記穴部の一方を当て部材で塞いで底を形成する工程と、前記穴部の底に溶接材を設置する工程と、穴部の穴径よりも外径が小さい摩擦棒を回転させながら穴部に圧入する工程と、を備え、前記穴部とほぼ同径の貫通孔が設けられた板状スペーサを、前記母材と前記当て部材との間に前記貫通孔を穴部に一致させて挟み込む技術が採用される。
【０００８】
また、請求項２記載の穴部の肉盛り装置では、母材を貫通した穴部の肉盛り装置であって、前記穴部の一方を塞ぐ当て部材と、該当て部材と前記母材との間に挟み込まれる板状スペーサと、穴部の穴径よりも外径が小さい摩擦棒と、摩擦棒を回転させるとともに穴部に圧入する駆動手段と、を備え、前記板状スペーサは、前記穴部とほぼ同径で肉盛り時に前記穴部に一致させる貫通孔が設けられている技術が採用される。
【０００９】
これらの穴部の肉盛り方法および穴部の肉盛り装置では、穴部とほぼ同径の貫通孔が設けられた板状スペーサを、母材と当て部材との間に貫通孔を穴部に一致させて挟み込むことにより、塑性流動した溶接材の流れを貫通孔の内側面で穴部の軸方向に向けることができ、穴部の底近傍における接合不良および変形等を防ぐことができる。また、穴部の底近傍においても、母材と流動部とがスムーズに擦れ合うことにより、酸化皮膜除去効果も向上させることができる。
【００１０】
【発明の実施の形態】
以下、本発明に係る穴部の肉盛り方法および肉盛り装置の一実施形態を、図１を参照しながら説明する。
この図において、符号１は摩擦棒、２は駆動手段、３は母材、４はスリーブ、５は当て板、６は穴付き板である。
【００１１】
本実施形態の肉盛り方法に用いる肉盛り装置は、図１の（ａ）に示すように、例えば、アルミ合金で形成された母材３（本実施形態では、厚さが均一な板状のもの）に空けられた比較的小さな穴部３ａ（例えば、ピン用の穴部）の内側を肉盛りして修理する装置であって、工具鋼で形成され回転可能なプラグである摩擦棒１と、該摩擦棒１を所定の回転数で回転駆動するとともに軸方向に進退させる駆動手段２と、母材３の下面側において穴部３ａの開口端を閉塞するように当てがう当て板（当て部材）５と、当て板５と母材３との間に挟み込まれる穴付き板（板状スペーサ）６とを備えている。
また、穴付き板６には、穴部３ａとほぼ同径で肉盛り時に穴部３ａに一致させる貫通孔６ａが設けられている。
【００１２】
この肉盛り装置を用いた穴部３ａの肉盛り方法を、以下に説明する。
まず、母材３の下面側において穴部３ａの開口端を閉塞するように当て板５を当てがう。この際、穴付き板６を、母材３と当て板５との間に貫通孔６ａを穴部３ａに一致させて挟み込ませる。
さらに、穴部３ａ内にその内径より僅かに小さい外径のスリーブ（溶接材）４を挿入する。
【００１３】
なお、スリーブ４は、溶接材として母材３と同じ材料であるアルミ合金で形成されている。また、当て板５および穴付き板６は、いずれも母材３と異なる材料（例えば、鉄ベースの合金）で形成されている。
また、摩擦棒１は、円柱状に形成されその外径がスリーブ４の内径より大きく、かつ穴部３ａの内径より小さく設定されている。
【００１４】
次に、この状態で、摩擦棒１を駆動手段２によって、所定の回転数で回転させるとともに、図１の（ｂ）に示すように、スリーブ４内に圧入させる。
このとき、主に摩擦棒１の先端面１ａの外縁部がスリーブ４に接触して摩擦熱を発生させる。そして、スリーブ４および母材３は、この摩擦熱によってスリーブ４および母材３を形成するアルミ合金の融点より低い温度で、かつ塑性流動させるのに十分な温度まで加熱される。
【００１５】
そして、摩擦棒１が圧入されることによって、先端面１ａでスリーブ４の塑性化成分を流動させてスリーブ４と母材３とが混合、接合し、穴部３ａの内側が肉盛りされる。
さらに、塑性化された溶接材４は、摩擦棒１の回転、圧入に伴って、貫通孔６ａの内側面で穴部３ａの軸方向上方に流れが向けられ、穴部３ａの底近傍での接合不良および変形等を防ぐことができる。また、穴部３ａの底近傍においても、母材３ａと流動する溶接材４とがスムーズに擦れ合うことにより、酸化皮膜の除去が良好に行われる。
【００１６】
次に、上記実施形態の他の例を、図２を参照して説明する。
【００１７】
上記実施形態では、先端面１ａが平らな摩擦棒１と表面が平らな当て板５とを用いたが、他の例として、図２に示すように、先端面１１ａが先端側に向けて凸状（テーパ状）に形成された摩擦棒１１と、先端面１１ａの形状に応じた凹状の有底穴１３ａを穴部３ａに当てる位置に有する当て板１３とを採用しても構わない。なお、有底穴１３は、穴部３ａとほぼ同じ内径に形成されている。
また、上記実施形態では、円筒状の溶接材としてスリーブ４を用いたが、他の例として、図２の（ａ）に示すように、穴部３ａの内径より小さい外径に成形された円柱状（ペレット状）の溶接材１４を採用しても構わない。
【００１８】
この例では、溶接材１４を有底穴１３ａの底面に載置し、この状態で、摩擦棒１１を駆動手段２によって回転させるとともに、図２の（ｂ）に示すように、穴部３ａ内に圧入させる。
このとき、高速回転する摩擦棒１１の先端面１１ａが溶接材４に接触して、摩擦棒１１と溶接材４との間、もしくは溶接材４と当て板１３の有底穴１３ａとの間で瞬間的に大きな摩擦熱を発生させる。
【００１９】
そして、塑性化された溶接材４は、図２の（ｂ）に示すように、摩擦棒１１の回転、圧入に伴って、有底穴１３ａの中で径方向に流動するとともに、有底穴１３ａの内側面および穴付き板６の貫通孔６ａの内側面によって穴部３ａの軸方向上方に流れが向けられる。この後、溶接材４は、母材３と摩擦棒１１との間の隙間に流動させられて該隙間を埋める。この際、溶接材４と母材３とが混合、接合し、穴部３ａの内側が肉盛りされる。
【００２０】
したがって、この例では、穴付き板６を挟み込んで行うことによる溶接材の整流効果に加えて、以下のような効果が得られる。すなわち、摩擦棒１１の先端面１１ａが圧入方向に向けて凸状に形成されているとともに、有底穴１３ａが摩擦棒１１の先端面１１ａの形状に応じた凹状に形成されているので、塑性化した溶接材４が摩擦棒１１の先端面１１ａおよび有底穴１３ａの底面に沿って流動することにより、径方向の流れをスムーズに軸方向へ変えることができる。
【００２１】
本発明は、次のような実施形態をも含むものである。
上記実施形態では、母材３と同じ材料の溶接材を用いたが、溶接材料として肉盛りに適用可能な材料であれば、他の材料で溶接材を形成しても構わない。
溶接材の形状は円筒状または円柱状にしたが、これに限るものではなく、他の形状のものを採用しても構わない。例えば、十分な摩擦熱が得られるものであれば、粒状の溶接材を適用してもよい。
【００２２】
【発明の効果】
本発明によれば、以下の効果を奏する。
請求項１記載の穴部の肉盛り方法および請求項２記載の穴部の肉盛り装置によれば、穴部とほぼ同径の貫通孔が設けられた板状スペーサを、母材と当て部材との間に貫通孔を穴部に一致させて挟み込むことにより、穴部の底近傍において溶接材を穴部の軸方向に流動させ、底近傍での接合不良および変形等の防止および酸化皮膜除去効果の向上を図ることができ、接合強度を向上させて良好な接合が可能になる。

BACKGROUND OF THE INVENTION
The present invention relates to a hole filling method and a build-up device for building up a hole in a base material for wear or crack repair.
[0002]
[Prior art]
In order to repair wear and cracks in hole parts such as machine parts, there is a case where the inside of the hole part is piled up. The hole was built up by fusion welding such as (inert gas arc welding using a tungsten electrode).
[0003]
When repairing a hole in a light metal such as an aluminum alloy, when overlaying by fusion welding such as TIG welding is performed, the temperature becomes considerably high, so the heat causes deformation of the parts and reduction of the mechanical strength of the material. There was a case where poor overlay occurred.
As a countermeasure, for example, as shown in FIG. 3 (a), as a means for building up and repairing the inside of a relatively small hole 3a formed in the base material 3 formed of an aluminum alloy, The friction plate 1 is rotated by the driving means 2 such as a motor in a state where the contact plate 5 is applied so as to close the opening end of the hole 3a on the lower surface side of 3 and the welding material 4 is put in the hole 3a. At the same time, as shown in FIG. 3B, a means for press-fitting into the hole 3a has been proposed.
[0004]
According to this means, since a large frictional heat is instantaneously generated between the friction rod 1 and the welding material 4 rotating at high speed or between the welding material 4 and the contact plate 5, the plasticized welding material 4 is used. Is plastically flowed by the friction rod 1 and is pushed into the gap between the friction rod 1 and the base material 3 to fill the gap, and the welding material 4 and the base material 3 are mixed and joined, and the inside of the hole 3a is It is meat filled.
In such a hole build-up means, the temperature is not raised to the melting point of the base material 3 and the welding material 4 is plastically flowed instantaneously, so that deformation and strength reduction can be suppressed, and good build-up of the hole 3a is achieved. Is possible.
[0005]
[Problems to be solved by the invention]
However, the following problems remain in the conventional overlaying means. That is, since the plastic flow at the bottom of the hole is small, there is a risk that poor bonding occurs between the base material and the welding material in the vicinity of the bottom. Further, when the welding material is pushed out by the friction rod, a radial flow occurs at the bottom of the hole, and the hole may be deformed at this portion. Further, the effect of removing the oxide film due to rubbing between the fluidized portion of the welding material and the base material is reduced, and there is a possibility that bonding failure or the like may occur due to the remaining oxide film.
[0006]
The present invention has been made in view of the above-described problems, and prevents the bonding failure and deformation in the vicinity of the bottom of the hole, and prevents the oxide film from remaining, thereby obtaining a good bonding. An object of the present invention is to provide a build-up method and a build-up apparatus.
[0007]
[Means for Solving the Problems]
The present invention employs the following configuration in order to solve the above problems. That is, in the method of building up the hole according to claim 1, the method of building up the hole that penetrates the base material, the step of closing one of the holes with a contact member to form the bottom, and the hole A step of installing a welding material on the bottom of the hole, and a step of press-fitting the hole into the hole while rotating a friction rod having an outer diameter smaller than the hole diameter of the hole, the through hole having substantially the same diameter as the hole A technique is adopted in which the plate-like spacer provided with is sandwiched between the base material and the abutting member so that the through-hole is aligned with the hole.
[0008]
Further, in the hole build-up device according to claim 2, the hole build-up device penetrates the base material, and includes a member for closing one of the hole portions, and the corresponding member and the base material. A plate-like spacer sandwiched therebetween, a friction rod having an outer diameter smaller than the hole diameter of the hole portion, and a driving means for rotating the friction rod and press-fitting into the hole portion, the plate-like spacer comprising the hole A technique is adopted in which a through-hole is provided that has substantially the same diameter as the portion and matches the hole when being built.
[0009]
In these hole-filling methods and hole-filling devices, a plate-like spacer having a through-hole having substantially the same diameter as the hole is used, and the through-hole is formed between the base material and the abutting member. By sandwiching them in a matching manner, the flow of the plastically flowing welding material can be directed in the axial direction of the hole portion on the inner side surface of the through hole, and it is possible to prevent joint failure and deformation in the vicinity of the bottom of the hole portion. Further, even in the vicinity of the bottom of the hole portion, the base material and the fluidized portion smoothly rub against each other, so that the effect of removing the oxide film can be improved.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, one embodiment of a method for piling up a hole and a piling device according to the present invention will be described with reference to FIG.
In this figure, reference numeral 1 is a friction rod, 2 is a driving means, 3 is a base material, 4 is a sleeve, 5 is a contact plate, and 6 is a plate with a hole.
[0011]
As shown in FIG. 1A, the build-up apparatus used in the build-up method of the present embodiment is, for example, a base material 3 formed of an aluminum alloy (in this embodiment, a plate-like plate having a uniform thickness). Friction rod 1 which is a device that builds up and repairs the inside of a relatively small hole 3a (for example, a hole for a pin), and is a rotatable plug formed of tool steel, , A driving means 2 for rotating the friction rod 1 at a predetermined rotational speed and advancing and retreating in the axial direction, and a contact plate (abutment) for closing the opening end of the hole 3a on the lower surface side of the base material 3 Member) 5 and a plate with holes (plate spacer) 6 sandwiched between the contact plate 5 and the base material 3.
Further, the holed plate 6 is provided with a through-hole 6a that has substantially the same diameter as the hole 3a and matches the hole 3a when building up.
[0012]
A method for building up the hole 3a using this build-up device will be described below.
First, the contact plate 5 is applied so as to close the open end of the hole 3 a on the lower surface side of the base material 3. At this time, the holed plate 6 is sandwiched between the base material 3 and the contact plate 5 with the through hole 6a being aligned with the hole 3a.
Further, a sleeve (welding material) 4 having an outer diameter slightly smaller than the inner diameter is inserted into the hole 3a.
[0013]
The sleeve 4 is formed of an aluminum alloy that is the same material as the base material 3 as a welding material. Further, both the contact plate 5 and the holed plate 6 are made of a material different from the base material 3 (for example, an iron-based alloy).
The friction rod 1 is formed in a columnar shape and has an outer diameter larger than the inner diameter of the sleeve 4 and smaller than the inner diameter of the hole 3a.
[0014]
Next, in this state, the friction rod 1 is rotated at a predetermined rotational speed by the driving means 2 and is press-fitted into the sleeve 4 as shown in FIG.
At this time, the outer edge portion of the tip surface 1a of the friction rod 1 mainly contacts the sleeve 4 to generate frictional heat. The sleeve 4 and the base material 3 are heated to a temperature lower than the melting point of the aluminum alloy forming the sleeve 4 and the base material 3 by this frictional heat and sufficient to cause plastic flow.
[0015]
When the friction rod 1 is press-fitted, the plasticizing component of the sleeve 4 is caused to flow at the front end surface 1a, the sleeve 4 and the base material 3 are mixed and joined, and the inside of the hole 3a is built up.
Further, the plasticized welding material 4 is flowed upward in the axial direction of the hole 3a on the inner surface of the through hole 6a with the rotation and press-fitting of the friction rod 1, and near the bottom of the hole 3a. Bonding failure and deformation can be prevented. Further, even in the vicinity of the bottom of the hole 3a, the base material 3a and the flowing welding material 4 rub against each other smoothly, so that the oxide film can be satisfactorily removed.
[0016]
Next, another example of the above embodiment will be described with reference to FIG.
[0017]
In the above embodiment, the friction rod 1 having a flat tip surface 1a and the contact plate 5 having a flat surface are used, but as another example, as shown in FIG. 2, the tip surface 11a is convex toward the tip side. The friction rod 11 formed in a shape (tapered shape) and the contact plate 13 having a concave bottomed hole 13a corresponding to the shape of the tip end surface 11a at the position where the hole 3a is applied may be employed. The bottomed hole 13 is formed with substantially the same inner diameter as the hole 3a.
Moreover, in the said embodiment, although the sleeve 4 was used as a cylindrical welding material, as shown to (a) of FIG. 2, as another example, the circle | round | yen shape | molded by the outer diameter smaller than the internal diameter of the hole 3a. A columnar (pellet-like) welding material 14 may be employed.
[0018]
In this example, the welding material 14 is placed on the bottom surface of the bottomed hole 13a, and in this state, the friction rod 11 is rotated by the driving means 2 and, as shown in FIG. Press fit into.
At this time, the tip surface 11a of the friction rod 11 rotating at high speed comes into contact with the welding material 4, and between the friction rod 11 and the welding material 4, or between the welding material 4 and the bottomed hole 13a of the contact plate 13. Instantly generates large frictional heat.
[0019]
As shown in FIG. 2B, the plasticized welding material 4 flows in the radial direction in the bottomed hole 13a with the rotation and press-fitting of the friction rod 11, and the bottomed hole The flow is directed upward in the axial direction of the hole 3a by the inner surface of 13a and the inner surface of the through hole 6a of the plate 6 with holes. Thereafter, the welding material 4 is caused to flow in the gap between the base material 3 and the friction rod 11 to fill the gap. At this time, the welding material 4 and the base material 3 are mixed and joined, and the inside of the hole 3a is built up.
[0020]
Therefore, in this example, in addition to the rectifying effect of the welding material by sandwiching the plate 6 with the hole, the following effects can be obtained. That is, the tip surface 11a of the friction rod 11 is formed in a convex shape toward the press-fitting direction, and the bottomed hole 13a is formed in a concave shape corresponding to the shape of the tip surface 11a of the friction rod 11, so that plasticity is achieved. Since the welded material 4 that has been converted to flow along the tip surface 11a of the friction rod 11 and the bottom surface of the bottomed hole 13a, the radial flow can be smoothly changed to the axial direction.
[0021]
The present invention includes the following embodiments.
In the above embodiment, the welding material of the same material as that of the base material 3 is used. However, the welding material may be formed of other materials as long as the welding material is applicable to overlaying.
The shape of the welding material is cylindrical or columnar, but is not limited thereto, and other shapes may be employed. For example, a granular welding material may be applied as long as sufficient frictional heat can be obtained.
[0022]
【The invention's effect】
The present invention has the following effects.
According to the method for building up a hole according to claim 1 and the device for building up a hole according to claim 2, a base material and a contact member are provided with a plate-like spacer provided with a through-hole having substantially the same diameter as the hole. By sandwiching the through hole between the hole and the hole, the welding material flows in the axial direction of the hole near the bottom of the hole, preventing bonding failure and deformation near the bottom and removing the oxide film. The effect can be improved, and the bonding strength can be improved to achieve good bonding.
