Description

この発明は、液体ホーニング加工作業の際に用いる補助器具、詳しくは液体ホーニング加工の際に、冶具や周辺機器を研磨材の衝突から保護する遮蔽具に関するものである。   The present invention relates to an auxiliary device used in a liquid honing process, and more particularly to a shield that protects a jig and peripheral devices from collision of abrasives during a liquid honing process.

水と研磨材との混合物であるスラリーを加工対象物に向けて高速で投射し、その表面の加工を行う液体ホーニングは、金属加工、その他の産業分野において広く実施されている。この液体ホーニングは、圧縮空気によってスラリーを噴射する為、加工対象物だけではなく、冶具や周辺機器にもスラリーが飛び散り、これによって、それらの表面が摩耗させられるなど、好ましからざる影響を与えることがあった。
アルミナ等の切削性の強い研磨材を用いた場合には、この現象は特に顕著であり、加工対象物の穴を通過した噴射スラリーが衝突した箇所や、加工対象物表面で跳ね返った箇所などでは、局部的に激しい摩耗が発生することがあった。
なし なし
Liquid honing in which a slurry, which is a mixture of water and an abrasive, is projected at a high speed toward a workpiece and the surface thereof is processed is widely implemented in metal processing and other industrial fields. In this liquid honing, the slurry is sprayed by compressed air, so that the slurry scatters not only on the workpiece but also on the jigs and peripheral devices, which can cause undesirable effects such as wear on the surface. there were.
This phenomenon is particularly noticeable when using an abrasive material such as alumina that has a high machinability, such as where the spray slurry that has passed through the hole in the workpiece has collided or where it has bounced off the surface of the workpiece. In some cases, severe wear occurred locally.
None None

この為、図1に示す様に、噴射ガン1に対向している加工対象物2の後方に天然ゴム等の耐摩耗性を有する遮蔽板3を位置させ、加工対象物2の穴4を通過したり、加工対象物2の表面で跳ね返ったスラリー13が、周辺機器5や冶具などに向かって飛び散らない様に遮蔽することが行われている。しかしながら、時間経過と共に、遮蔽板3もスラリー13の衝突によって摩耗し、ついには局部摩耗箇所14に穴があいてしまうという現象が発生しており、スラリー13の衝突による摩耗を効果的に防止できる方策が求められていた。本発明者はこの要望を実現出来る遮蔽具を実現すべく研究を行った結果、遮蔽具の形状を工夫することにより、スラリー13の衝突によっても摩耗しにくい摩耗防止用遮蔽具を開発することに成功し、本発明としてここに提案するものである。   For this reason, as shown in FIG. 1, a shielding plate 3 having wear resistance such as natural rubber is positioned behind the workpiece 2 facing the spray gun 1 and passes through the hole 4 of the workpiece 2. In other words, the slurry 13 that bounces off the surface of the workpiece 2 is shielded from splashing toward the peripheral device 5 or the jig. However, with the passage of time, the shielding plate 3 is also worn by the collision of the slurry 13, and finally a phenomenon occurs in which a local wear spot 14 is perforated, so that the wear due to the collision of the slurry 13 can be effectively prevented. Measures were sought. As a result of conducting research to realize a shield capable of realizing this demand, the present inventor has developed a wear-preventing shield that is not easily worn by the collision of the slurry 13 by devising the shape of the shield. It has been successful and is proposed here as the present invention.

有底円筒状をなした筒状部の開口端12側に拡径したつば部9が一体的に形成されている耐摩耗性を有する天然ゴム製のカップ型遮蔽材7の筒状部10を、該筒状部10の外径よりわずかに大きい内径を有する透孔8が形成されている耐摩耗性を有する天然ゴム製の遮蔽板6の前記透孔8に嵌め込み、該カップ型遮蔽材7の開口端12を噴射ガン1の方向に指向させ、かつスラリー13の衝突により局部的に激しい摩耗が生じるおそれのある箇所にこのカップ型遮蔽材7が位置する様に配置せしめることにより、上記課題を解決した。 A cylindrical portion 10 of a natural rubber cup-type shielding material 7 having a wear-resistant collar 9 integrally formed with a flange 9 having an enlarged diameter on the opening end 12 side of a cylindrical portion having a bottomed cylindrical shape. The cup-shaped shielding material 7 is fitted into the through-hole 8 of the wear-resistant natural rubber shielding plate 6 in which the through-hole 8 having an inner diameter slightly larger than the outer diameter of the cylindrical portion 10 is formed. The opening end 12 is directed toward the spray gun 1 and the cup-type shielding material 7 is disposed at a location where severe wear may occur locally due to the collision of the slurry 13. Solved.

噴射ガン1から噴射されたスラリー13は、加工対象物2の穴4を通過したり、跳ね返ったりして、この摩耗防止用遮蔽具に達するが、スラリー13の到達位置には、カップ型遮蔽材7が位置しているので、スラリー13はその開口端12からカップ型遮蔽材7の内側空間に導かれて、その底部11に溜まり、障壁となって噴射ガン1から噴射される運動エネルギーを持ったスラリー13がこの底部11に達するのを阻止すると共に、カップ型遮蔽材7の内部空間で反射したスラリー13と噴射ガン1から噴射された運動エネルギーを持ったスラリー13とが互いに衝突干渉することにより、噴射ガン1から噴射されたスラリー13の運動エネルギーは著しく減衰させられる。
従って、従来の遮蔽板3の様に、継続的使用によってスラリー13の衝突箇所に穴があくという現象は起こらず、局部的な摩耗を著しく低減させることが出来る。又、長期間の
供用によってカップ型遮蔽材7の一部に摩耗が生じたとしても、このカップ型遮蔽材7だけを取り替えればいつまでも使用することが可能で、極めて高い実用性を有する。
The slurry 13 sprayed from the spray gun 1 passes through the hole 4 of the workpiece 2 or rebounds and reaches the wear prevention shielding tool. 7 is located, the slurry 13 is guided from the opening end 12 to the inner space of the cup-shaped shielding material 7 and accumulates in the bottom 11 thereof, and has kinetic energy injected from the injection gun 1 as a barrier. The slurry 13 is prevented from reaching the bottom 11 and the slurry 13 reflected in the internal space of the cup type shielding material 7 and the slurry 13 having kinetic energy injected from the injection gun 1 collide with each other. Thus, the kinetic energy of the slurry 13 injected from the injection gun 1 is significantly attenuated.
Therefore, unlike the conventional shielding plate 3, the phenomenon that the slurry 13 is punctured by continuous use does not occur, and local wear can be remarkably reduced. Further, even if a part of the cup type shielding material 7 is worn due to long-term use, it can be used forever if only the cup type shielding material 7 is replaced, and has extremely high practicality.

板状の遮蔽板3とカップ型の遮蔽材7を組合せて摩耗防止用遮断具を構成した点に最大の特徴が存する。   The greatest feature lies in that the anti-wear breaker is configured by combining the plate-shaped shielding plate 3 and the cup-shaped shielding material 7.

図2はこの発明に係る液体ホーニング加工に用いる摩耗防止用遮蔽具の一実施例の説明図である。この発明に係る液体ホーニング加工に用いる摩耗防止用遮蔽具は、板状をなした遮蔽板6とカップ型遮蔽材7とから構成されており、遮蔽板6は耐摩耗性を有する天然ゴムを素材とする板状体であり、その所望位置には表裏を貫通した円形の透孔8があけられてる。 FIG. 2 is an explanatory view of an embodiment of a wear preventing shield used in the liquid honing process according to the present invention. The wear-preventing shielding tool used in the liquid honing process according to the present invention comprises a plate-shaped shielding plate 6 and a cup-shaped shielding material 7, and the shielding plate 6 is made of natural rubber having wear resistance. A circular through-hole 8 penetrating the front and back is opened at a desired position.

一方、カップ型遮蔽材7は、前記遮蔽板6と同様、耐摩耗性を有する天然ゴムを素材とするものであり、筒状部10と底部11からなる有底円筒状をなし、開口端12側に拡径したつば部9が一体的に形成されたカップ状を呈しており、筒状部10の外径は、前記遮蔽板6の透孔8の内径よりわずかに小さく形成されている。そして、このカップ型遮蔽材7は、その筒状部10が遮蔽板6の透孔8に嵌め込まれ、つば部9の裏面が遮蔽板6の表面に密着した状態で、遮蔽板6に取付けられている。 On the other hand, the cup-type shielding material 7 is made of a natural rubber having wear resistance , like the shielding plate 6, and has a bottomed cylindrical shape composed of a cylindrical portion 10 and a bottom portion 11, and has an open end 12. It has a cup shape integrally formed with a flange portion 9 whose diameter is increased on the side, and the outer diameter of the cylindrical portion 10 is slightly smaller than the inner diameter of the through hole 8 of the shielding plate 6. The cup-shaped shielding material 7 is attached to the shielding plate 6 with the tubular portion 10 fitted in the through hole 8 of the shielding plate 6 and the back surface of the collar portion 9 being in close contact with the surface of the shielding plate 6. ing.

この発明に係る摩耗防止用遮蔽具は、上記の通りの構成を有するものであり、図2に示す様に、カップ型遮蔽材7の開口端11を噴射ガン1の方向を向け、かつ、噴射されたスラリー13が直接あるいは間接的に衝突して局部的に激しい摩耗が発生するおそれのある部分に、このカップ型遮蔽材7が位置する様に配置して使用に供する。   The wear prevention shield according to the present invention has the above-described configuration. As shown in FIG. 2, the opening end 11 of the cup type shielding material 7 is directed to the spray gun 1 and sprayed. The cup-type shielding material 7 is disposed so as to be used for use in a portion where the worn slurry 13 may collide directly or indirectly to generate severe wear locally.

このとき、噴射ガン1から噴射されたスラリー13は、加工対象物2の穴4を通過したり、跳ね返ったりして、摩耗防止用遮蔽具に達するが、スラリー13の到達位置には、カップ型遮蔽材7が位置しているので、スラリー13はその開口端12からカップ型遮蔽材7の内側空間に導かれて、その底部11に溜まり、障壁となって噴射ガン1から噴射される運動エネルギーを持ったスラリー13がこの底部11に達するのを阻止すると共に、カップ型遮蔽材7の内部空間で反射したスラリー13と噴射ガン1から噴射された運動エネルギーを持ったスラリー13とが互いに衝突干渉することにより、噴射ガン1から噴射されたスラリー13の運動エネルギーは著しく減衰させられる。   At this time, the slurry 13 sprayed from the spray gun 1 passes through the hole 4 of the workpiece 2 or rebounds to reach the wear prevention shielding tool. Since the shielding material 7 is located, the slurry 13 is guided from the opening end 12 to the inner space of the cup-shaped shielding material 7 and accumulated in the bottom 11, and the kinetic energy injected from the injection gun 1 as a barrier. And the slurry 13 reflected in the inner space of the cup type shielding material 7 and the slurry 13 having kinetic energy injected from the injection gun 1 collide with each other. As a result, the kinetic energy of the slurry 13 injected from the injection gun 1 is significantly attenuated.

従って、従来の遮蔽板3の様に、継続的使用によってスラリー13の衝突箇所に穴があくという現象は起こらず、局部的な摩耗を著しく低減させることが出来る。又、長期間の供用によってカップ型遮蔽材7の一部に摩耗が生じたとしても、このカップ型遮蔽材7だけを取り替えればいつまでも使用することが可能である。   Therefore, unlike the conventional shielding plate 3, the phenomenon that the slurry 13 is punctured by continuous use does not occur, and local wear can be remarkably reduced. Further, even if a part of the cup type shielding material 7 is worn due to long-term use, it can be used forever if only the cup type shielding material 7 is replaced.

なお、図3はカップ型遮蔽材7の内径、長さ及びスラリー13の噴射角度をいく通りかに変化させて、それぞれの場合のカップ型遮蔽材7の切削された量、つまり摩耗した量を記した表であり、この表からも、この発明に係る摩耗防止用遮蔽具が局部的な摩耗阻止に極めて有効であることは明らかである。ちなみに、同表の最下欄に記載されている通り、内径が35mmで長さが60mmであるところの、内径が小さく、奥行きが長いカップ型遮蔽材7においては、スラリー13が底部11に特に溜まりやすく、噴射ガン1から噴射された運動エネルギーを持ったスラリー13が底部11にほとんど到達せず、従って、底部11がほとんど摩耗しないことが明らかになった。   In FIG. 3, the inner diameter and length of the cup type shielding material 7 and the spray angle of the slurry 13 are changed in several ways, and the amount of cutting of the cup type shielding material 7 in each case, that is, the amount of wear. From this table, it is clear that the wear prevention shield according to the present invention is extremely effective for local wear prevention. Incidentally, as described in the bottom column of the table, in the cup-shaped shielding material 7 having a small inner diameter and a long depth, where the inner diameter is 35 mm and the length is 60 mm, the slurry 13 is particularly at the bottom 11. It became clear that the slurry 13 having the kinetic energy ejected from the spray gun 1 hardly reached the bottom portion 11 and thus the bottom portion 11 was hardly worn.

金属加工、半導体製造、プラスチック加工など液体ホーニング加工を行う各種産業分野において広く利用可能である。   It can be widely used in various industrial fields that perform liquid honing such as metal processing, semiconductor manufacturing, and plastic processing.
