Description
前記課題を解決するため、本発明の請求項１に係る発明は、導入孔に供給された高圧水に研磨材を混入したアブレシブウォータージェットをワークに噴射して加工するアブレシブウォータージェットノズルであって、前記研磨材が供給口から室内に空気とともに吸い込まれて導入される気室からなる混合室と、この混合室の上方に配設され前記導入孔が形成され前記高圧水を噴出するウォーターノズルと、このウォーターノズルの下流部であって前記混合室の中央部に入り込むように配設され、当該ウォーターノズルから噴出されたウォータージェットに前記研磨材を混入させ、前記混合室内に当該ウォータージェットを導通孔の開口部から噴出するミキシングノズルと、このミキシングノズルの下流部に配設され前記ウォータージェットを導入して前記アブレシブウォータージェットを前記ワークに噴射するアブレシブノズルと、を備え、前記供給口は、前記開口部よりも前記ウォータージェットの噴出方向に対して上流側に前記研磨材を供給するように前記混合室に配設され、前記ミキシングノズルの導通孔の孔径は、前記ウォーターノズルの孔径よりも大きく形成され、当該導通孔を通過するウォータージェットと当該導通孔の内周面との間に形成された隙間に前記混合室内に滞留させた研磨材を空気とともに吸引して当該導通孔内で前記ウォータージェットに混入させること、を特徴とする。 In order to solve the above-mentioned problem, the invention according to claim 1 of the present invention is an abrasive water jet nozzle that injects and processes an abrasive water jet in which abrasive is mixed into high-pressure water supplied to an introduction hole, onto a workpiece. A mixing chamber composed of an air chamber into which the abrasive material is sucked and introduced into the room from the supply port, and a water nozzle disposed above the mixing chamber to form the introduction hole and eject the high-pressure water; The downstream portion of the water nozzle is disposed so as to enter the central portion of the mixing chamber, the abrasive is mixed into the water jet ejected from the water nozzle, and the water jet is conducted into the mixing chamber. and mixing nozzle ejected from the opening of the hole, the water jet is disposed on the downstream portion of the mixing nozzle And a abrasive nozzle for injecting the abrasive water jet to the workpiece by entering the supply port, so as to supply the abrasive on the upstream side relative to the ejection direction of the water jet than the opening The hole diameter of the conduction hole of the mixing nozzle disposed in the mixing chamber is formed larger than the hole diameter of the water nozzle, and is formed between the water jet passing through the conduction hole and the inner peripheral surface of the conduction hole. The abrasive material retained in the mixing chamber in the gap is sucked together with air and mixed into the water jet in the conduction hole.
