本発明はサンドブラストノズルの改良に関ず°るもので
ある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in sandblasting nozzles.
従来サンドブラストノズルは、ノズルホルタ−中に硬質
金属製又はセラミック製の大径ノズルを □嵌め
、エアホースをノズルホルダーに接続して、研掃材を含
んだブラスト気流をノズルから前方へ噴出させている。In conventional sandblasting nozzles, a large diameter nozzle made of hard metal or ceramic is fitted into a nozzle holter, an air hose is connected to the nozzle holder, and a blast air stream containing abrasive material is ejected forward from the nozzle.
ブラスト気流はノズル前方に置かれた対象物に対し1本

のであるか、ブラスト □気流の直径によって
加工範囲が決まるから、対象物の広い面積をブラスト処
理するには、ノズルを何度も繰り返し往復してブラスト
気流を対象物の表面に当てねばならなかった。The blasting airflow forms a single straight jet toward the object placed in front of the nozzle, and adds blasting force to the object. To blast a large area, the nozzle must be moved back and forth many times to apply the blast air stream to the surface of the object.
又、管の内面或は対象物の凹んだ空間をブラスト処理す
るためには、ノズル先端を7Ft、の内面に向けた状態
で管軸周りを回転させる特別な装置を必要とした。In addition, in order to blast the inner surface of the tube or the recessed space of the object, a special device was required to rotate the nozzle around the tube axis with the nozzle tip facing the inner surface of the 7Ft.

本発明はノズルホルダーの前壁に取り付ける小径ノズル
の向きを変えることによって、噴出するブラスト気流の
パターンを自由に変えることが出来、対象物の加工面に
合せて最適の気流パターンを形成出来る。In the present invention, by changing the direction of the small-diameter nozzle attached to the front wall of the nozzle holder, the pattern of the ejected blast airflow can be freely changed, and the optimum airflow pattern can be formed according to the processing surface of the object.
小径ノズルの先端を第2図の如く外向きに取付レノると
、フラスト気流のパターンは外航がりに噴出して対象物
の表面に衝撃を加える面積は拡大するから、ブラスト処
理のためノズルを対象物表面に向けて往復操作する回数
は減少する。If the tip of the small-diameter nozzle is installed with the tip facing outward as shown in Figure 2, the pattern of the blast airflow will be ejected outward and the area that will impact the surface of the object will be expanded, so it is difficult to attach the nozzle for blasting. The number of reciprocating operations toward the object surface is reduced.

とが出来る。In addition, by installing the small diameter nozzle with the tip facing the tangential direction of the nozzle holder, the blast airflow ejected from the 11T of the small diameter nozzle (5) becomes a spiral flow in the pipe, expands, and is ejected from the door. , blasting treatment can be applied to the inner surface of the tube.

たものである。Three straight holes (6) are made in the front wall (4) at equal intervals and parallel to the nozzle axis, and the small diameter nozzles (5) shown in Fig. 3 are fitted into the three straight holes (6), respectively. , nozzle holder (1)
At the same time, place the press plate (8) on the opening of the nozzle holder (1) and fix it to the end face of the nozzle holder (1) with the screw (9).
The wall (4) and each small diameter nozzle (5) are held down to prevent removal.

ているから、ブラスト気流流は3本の各小径ノズル(5
)に均等に分れて流入し、先端より3本の細いブラスト
気流の東となって噴出する。The blast airflow that has entered the inlet side of the nozzle is ejected from the nozzle pipe (2) and fills the chamber (3), forming a high-pressure air condition. Since the base ends of the three small-diameter nozzles (5) are open in the reservoir chamber (3), the blast air flow flows through each of the three small-diameter nozzles (5).
), and it flows out into three narrow blast airflows east of the tip.

If it is fixed, the nozzle will produce three thin blast airflows that spread in three directions in a 9 (11) pattern, making it possible to impact a wide area of the object's surface for efficient blasting.

PP出来る。In addition, in the embodiment shown in FIG. 1 or 4, a small diameter nozzle (5
) by horizontally recessing it in the tangential direction of the nozzle holder (1), it is possible to make the thin three-wood blast air stream ejected from the three-wood small-diameter nozzle (5) in a tangential direction. If this blast airflow is ejected into the pipe or at the recess of the object, the blasting airflow will eject along the inner surface of the object with a 4, 1, 11 rotation, and the blasting process will be performed. Alternatively, the side wall of the recess of the object can be blasted.
