- the collection device 30 for collecting the dust used a dust collector including a filter cloth for separating solid (dust) and gas from a solid-gas two-phase flow.
- a pulse jet method in which compressed air is intermittently blown onto the filter cloth was used.
- the method is not particularly limited, and for example, a mechanical method of removing by mechanical means may be used.
- the collection device 30 is provided with a discharge tool 31 for discharging dust that has been wiped off from the filter cloth and stored at the bottom of the collection device 30 to the outside of the collection device 30. ing.
- the discharge tool 31 uses a ball valve.
- a gate valve or a rotary valve may be used.
- the deburring device of this embodiment Next, deburring by the deburring device of this embodiment will be described.
- a process for roughening a 0.8 ⁇ 1.6 mm ceramic member as the workpiece W will be described.
- the term “small component to be processed” refers to a component to be processed having a diameter or side of approximately 30 mm or less, particularly for a component to be processed having a diameter or side of approximately 2 mm or less.
- the deburring device of the invention can be preferably used.
- the door 10a of the blasting chamber 10 is opened, the four tumblers 11 are taken out from the blasting chamber 10, and approximately the same amount of the workpieces W are put into the tumblers 11 respectively. Thereafter, the tumbler 11 is again engaged with the tumbler holder 11 a and set in the blasting chamber 10. Further, a required amount of the injection material (in this embodiment, zirconia) is put into the blasting chamber 10 and the door 10a is closed.
- the door 10a may be opened and closed manually, but may be performed by a mechanical operation such as an air cylinder.
- the spray material is transferred into the classification device 20 by the suction force generated by the recovery device 30, and then stored in the reservoir 21.
- the four tumblers 11 rotate by operating the motor 12a.
- the workpiece W in the tumbler 11 is agitated by this rotation.
- the compressed air generation source is operated, and negative pressure is generated inside the nozzle assembly 13 by, for example, injecting compressed air having a pressure of 0.7 MPa from the air nozzle 13b. Abrasives This negative pressure is supplied to the nozzle assembly 13, it is injected together with the compressed air from the injection port 13c o. Deburring is performed when the sprayed spray material collides with the surface of the workpiece W. Further, since the parts to be processed W are agitated by the rotation of the tumbler 11, all the parts to be processed W are sequentially exposed to the spray material, and all the parts to be processed W can be deburred.
- the dust transferred to the collection device 30 accumulates on the surface of the filter cloth inside the collection device 30. Dust accumulated on the surface of the filter cloth is removed by a pulse jet and stored at the bottom. The stored dust is discharged to the outside of the collection device 30 by opening the discharge tool 31.
- the operation of the compressed air supply source is stopped. At that time, the rotation of the motor 12a is still continued. This is because the spray material remaining in the tumbler 11 is discharged to the outside through the through hole 11i on the wall surface. Similarly, the operation of the collection device 30 is still continued. This is because the inside of the blasting chamber 10 is filled with the spray material and dust, so that these are stored (collected) in the reservoir 21 via the classifier 20, or the dust is collected by the recovery device 30. It is to do.
- the discharge auxiliary tool 21d is opened. By doing so, the propellant can be easily taken out.

- FIG. 13B shows a blasting device that opens and closes the door 10a by human power (manually).
- the specific gravity of the spray material is too small, a sufficient deburring effect cannot be obtained. If the specific gravity is too large, cracks and chips of the parts to be processed by the spray material are caused. When the average diameter of the spray material is smaller than 0.02 mm, a sufficient deburring effect cannot be obtained, and when it is larger than 0.08 mm, the collision of the spray material with the portion to be deburred becomes insufficient. If the injection pressure is too low, a sufficient deburring effect cannot be obtained, and if it is too high, cracks and chips occur in the parts to be processed.
- the specific gravity of the injection material is 1.0 to 3.0
- the average diameter of the injection material is 0.02 to 0.08 mm
- the distance from the opening of the nozzle tip that emits a jet of gas mixed with the propellant to the core member made of bulk ceramic that is the component to be processed W is shorter than 200 mm, the bulk in which the propellant is the component to be processed is sufficient. Injected material that is not sufficiently diffused to reach the core member made of the ceramic is wasted. On the other hand, if it is larger than 500 mm, the spray material collides with the part to be processed only sparsely, and deburring becomes insufficient. In order to perform efficient deburring without excessively spreading the jet airflow, it is preferable that the distance from the opening of the nozzle tip to the component to be processed is 200 mm or more and 500 mm or less. Furthermore, it is more preferable to set it to 200 mm or more and 300 mm or less. This moderate distance does not cause cracks or chipping in the parts to be processed.
- the core member has a rotational speed difference between the injection center and the injection outer peripheral portion of 32 mm / s or more and 64 mm / s or less in the injection range of the gas jet mixed with the injection material at the position of the core member made of bulk ceramics. It is good to tumbl. If the rotational speed difference is small, the deburring efficiency decreases. If the rotational speed difference is large, the core members collide with each other and cracks and chips occur. It is preferable to set the rotational speed difference to 32 mm / s or more and 64 mm / s or less for efficient deburring without causing the core member to collide with each other without cracking or chipping.
- the hardness of the spray material is too low, a sufficient deburring effect cannot be obtained, and if it is too high, the parts to be processed will be cracked or chipped.
- the core member made of bulk ceramic is an inductor member or a coil member of an electronic component manufactured by baking after molding and having a flange gap of 0.3 mm to 0.8 mm, and has a polygonal shape. Often made of alumina or silicon carbide. Therefore, an injection material having an average diameter of 0.02 to 0.08 mm is injected at least toward the gap between the plurality of flanges and the connection edge of the core part or the outer periphery of the core part. Thereby, since the injection material of a suitable magnitude
- the nozzle assembly 13 may use a so-called direct pressure type as long as a space for installing auxiliary equipment such as a pressurized tank can be secured.
- the tumbler holder 11a is used to rotate and hold the tumbler 11.
- an embodiment using the tumbler 11 having the drive shaft at the bottom by omitting the tumbler holder 11a can be configured. Please note that.
- the spray material is generally a deburring jet, such as a cut wire, ceramics, resin, plant, etc., cut from iron or iron-based shots or grit or thin lines (or rounded corners after cutting). Any material used as a material can be suitably applied.
- the deburring for the workpiece W formed from a hard and brittle material has been described.
- the deburring apparatus of the present invention does not depend on whether the workpiece W is a metal material or a non-metal material. It can be applied to the entire collection.

また、本発明は以下の詳細な説明により更に完全に理解できるであろう。しかしながら、詳細な説明および特定の実施例は、本発明の望ましい実施の形態であり、説明の目的のためにのみ記載されているものである。この詳細な説明から、種々の変更、改変が、当業者にとって明らかだからである。
出願人は、記載された実施の形態のいずれをも公衆に献上する意図はなく、開示された改変、代替案のうち、特許請求の範囲内に文言上含まれないかもしれないものも、均等論下での発明の一部とする。
本明細書あるいは請求の範囲の記載において、名詞及び同様な指示語の使用は、特に指示されない限り、または文脈によって明瞭に否定されない限り、単数および複数の両方を含むものと解釈すべきである。本明細書中で提供されたいずれの例示または例示的な用語(例えば、「等」)の使用も、単に本発明を説明し易くするという意図であるに過ぎず、特に請求の範囲に記載しない限り本発明の範囲に制限を加えるものではない。
明は本実施形態の構成に限られず、必要に応じて適宜変更することができる。
或いは第1の駆動伝達具11cとしてプーリ(図示せず)を用いる場合、第2の駆動伝達具12cは第1の駆動伝達具11cの溝の形状および溝の深さが同じであるプーリとする。
そこで、本実施形態では、第2の駆動伝達具12cは第1の駆動伝達具11cのスプロケットの山の高さおよび山と山との間隔が同じであるスプロケットを使用した。
本実施形態では、駆動伝達部材12fとしてチェーンを使用し、このチェーン12fがモータ(回転発生手段)12aの回転軸12bのスプロケット(第2の駆動伝達具)12cの回転力を、タンブラホルダ11a(図4には図示せず)の回転軸11bのスプロケット(第1の駆動伝達具)11cへ伝達するように連結している。従ってモータ(駆動伝達手段)12aの回転軸12bの回転に合わせて全てのタンブラホルダ11aが回転し、ひいては全てのタンブラ11が回転する。
さらに、タンブラ11の前記開口部11dに平行な断面形状に依らず、タンブラ11の底部に被処理部品Wが滞留するのを防ぐために、タンブラ11の底部付近に底部に向かってタンブラ11の内径(断面積)が連続的に小さくなる攪拌促進面11hを設けることが好ましい。この攪拌促進面11hの傾斜角度θ1は、実験によれば、115°から135°の範囲であると効果が顕著である。また、貫通穴11iは、タンブラ内部に噴射材が滞留しないように設けてあり、その径は、噴射材は通過できるが、被処理部品が該貫通穴より漏出しない程度の大きさである。
さらに、前記攪拌がより効果的に行われると噴射中の被処理部品Wがタンブラ11より漏出するためタンブラ11の開口部11d内面部に凸部形状のリング11jを取り付けるのがよい。内面に突き出る凸部の高さ(11k)は開口部より噴射材の進入を妨げない1~8mmが好ましく、より好ましくは3~6mmである。
このタンブラ11をタンブラホルダ11aを介して保持し回転する回転機構12は、該タンブラ11の傾斜角度θが前述の通り30°となるように配置した。
例えば、図9(A)では複数の角柱部材と複数の円柱部材とを係合させて回動自在なノズル・アセンブリ設置部材14を形成することで、ノズル・アセンブリ13をタンブラ11に対して上下左右方向に自由な位置に設定することができる。ノズル・アセンブリ設置部材14をブラスト加工室10内に設置する場所は特に限定されないが、本実施形態では、回転機構12のベース12d(図3参照)に配置した。具体的には、図9(B)に示すようにベース12d(図9(B)には図示せず)に対してノズル・アセンブリ設置部材14を構成するのに係合される第1、第2、第3、第4、および第5のアーム14a、14b、14c、14d、および14eは下記の通りである。
ベース12d :それぞれのノズル・アセンブリ13を設置するのに適した位置に円柱部材を設けている。
第1のアーム14a:角柱部材で形成されており、長手方向(図9(B)の紙面の垂直方向)に前記円柱部材と同径の第1の穴を有し、この第1の穴にはベース12dの円柱部材が嵌入されている。また、高さ方向(紙面の上下方向)には第2のアーム14bと同径の第2の穴を有する。
第2のアーム14b:円柱部材で形成されており、その下端が第1のアーム14aの第2の穴に嵌入されて係合する。
第3のアーム14c:角柱部材で形成されており、その一端(図9(B)の右側)の高さ方向に第2のアーム14bと同径の第3の穴を有し、この穴には第2のアーム14bの上端が嵌入されて係合する。また、他端には紙面に対して垂直方向に第5のアーム14eと同径の第4の穴を有し、この穴には第5のアーム14eの一端が嵌入されて係合する。
第4のアーム14d:角柱部材で形成されており、その一端(図9(B)の右側)の紙面に対して垂直方向に第5のアーム14eの円柱部材と同径の第5の穴を有し、この穴には第5のアーム14eの円柱部材が嵌入されて係合する。また、他端付近にはノズル・アセンブリ13を保持する保持具(図示せず)を有する。
第5のアーム14e:円柱部材で形成されており、その一端(図9(B)の紙面に対して奥)は、第3のアーム14cの第4の穴に嵌入されて係合し、その他端は、第4のアーム14dの第5の穴に嵌入されて係合する。
ここで、ノズル・アセンブリ13の保持具は特に限定されない。例えば、第4のアーム14dにボルト等で固定してもよく、クランプ機構によって保持してもよい。また、該保持具自体を回転可能に構成することで、該ノズル・アセンブリ13の設置の自由度を向上させてもよい。
この角度が73°より小さいと、貯留器21内部の噴射材がブリッチング現象(棚吊り)により取り出せなくなる現象が生じ易い。この現象を防ぐためには、該角度は大きい方がよいが、該角度が87°よりも大きくなると、後述の排出補助具21dが大型化してしまう。そこで、貯留器21から噴射材を効率よく取り出せ、かつ排出補助具21dを小さくするためには、該角度θ3は73°から87°の範囲で設定することが好ましい。そして、最下面付近には、貯留器21の内部に貯留されている噴射材をノズル・アセンブリ13に供給するための噴射材取り出し具21cが設置されている。噴射材取り出し具21cはホースH2(図2)を介し、ノズル・アセンブリ13の噴射材供給口13dと連接されている。さらに、第4の筒状体21bの最下面には、貯留器21に貯留された噴射材を交換等のために排出するために、排出補助具21dが設けられている。この排出補助具21dとしては、本実施形態ではバタフライバルブを使用したが、これに代えてボールバルブやゲートバルブを用いてもよい。なお、貯留器21の筒状体21aおよび21bは、円筒体でもよく、横断面が多角形の筒状体でもよい。本実施形態では横断面が四角形の筒状体を用いた。
また、回収時に濾布上に堆積したダストの除去(払い落とす)方式としては、圧縮空気を間欠的に濾布に吹き付けるパルスジェット方式を使用した。しかし、その方式は特に限定されるものではなく、例えば機械的手段によって払い落とす機械方式を用いてもよい。
図12に示すように、回収装置30には、濾布上から払い落とされて、回収装置30の底部に貯留されたダストを回収装置30の外部に排出するために、排出具31が設けられている。この排出具31は、本実施形態ではボールバルブを用いたが、これに代えて、例えばゲートバルブやロータリーバルブ等を用いてもよい。
次に、本実施形態のバリ取り装置によるバリ取りについて説明する。本実施例では、被処理部品Wとして0.8×1.6mmのセラミックス系部材を粗面化するための加工について説明する。なお、本明細書において「小型の被処理部品」とは、径または辺が概ね30mm以下程度の大きさの被処理部品を称し、特に径または辺が2mm以下程度の被処理部品に対して本発明のバリ取り装置を好適に用いることができる。
すなわち、被処理製品に割れや欠けが発生することなくバリ取りを行うには、噴射材の比重が1.0~3.0、噴射材の平均径が0.02~0.08mm、前記噴流の噴射圧力が0.03MPa以上0.15MPa以下に設定するのが好ましい。
回転速度差が小さいとバリ取りの効率が下がる。回転速度差が大きいとコア部材が互いに衝突して割れや欠けが発生する。
コア部材が互いに衝突することにより、割れや欠けが発生することなく、効率的なバリ取りをするには回転速度差を32mm/s以上64mm/s以下にするのが好ましい。
これにより、電子部品のインダクタ部材又はコイル部材のフランジの隙間に対し好適な大きさの噴射材を噴射できるので、効率的なバリ取りができる。
