Abstract
The utility model relates to a novel shot blasting nozzle which adopts the structure that a boss is arranged at an inner hole of a valve body; a diversion body is arranged on the boss; a distribution cone is arranged at the left side of the diversion body; the left end of the distribution cone is conical, and a cavity is arranged at the right side of the distribution cone; a reflector is arranged at the right side of the diversion body; the middle part of the reflector is conical; and the distribution cone, the diversion body and the reflector are connected by a screw together. The novel shot blasting nozzle is used for shot blasting strengthening on the surface of inner holes of metal parts, has good abrasion resistance and long service life, is uniform in surface spraying in shot blasting process, and is capable of improving the working efficiency and quality of shot blasting on the inner holes of the metal parts.
Description
Technical field
The utility model relates to a kind of novel shot-peening nozzle, and the shot peening strengthening that is used for the metal parts inner surface is handled, to improve the fatigue strength of metal parts.
Background technology
At machine industry, especially in the aircraft manufacturing industry, some metal parts carries out shot peening strengthening with compressed air shotblasting machine to piece surface usually and handles in order to improve fatigue strength.The used nozzle of part endoporus shot-peening adopted the formula single way jet structure of twitching one's mouth in the past, during work, needed the nozzle moving linearly; Part rotates simultaneously, and it is inhomogeneous that shot-peening sprays the part time job surface, influenced part shot-peening quality; Inefficiency, the nozzle wearability is bad, and service life is short.
Summary of the invention
The technical problem that the utility model will solve provides a kind of novel shot-peening nozzle; This novel shot-peening nozzle is used in the metal parts inner surface shot blasting strengthening; Not only wearability is good; Long service life, and the shot-blasting surface injection is evenly, can heighten the operating efficiency and the quality of metal parts inner shot-peening.
For overcoming the above problems, the concrete technical scheme of the utility model is following: a kind of novel shot-peening nozzle is provided with boss at the endoporus of valve body; Boss is provided with baffle, and the left side of baffle is provided with the shunting cone, and the left end of shunting cone is conical; The right side has cavity; The right side of baffle is provided with reflector, and the centre of reflector is conical, and shunting cone, baffle are connected through screw with reflector jointly.
The cavity on described baffle right side is 3～5 passages of circle distribution.
It is conical shunting cone that this novel shot-peening nozzle adopts distolateral, makes the high speed bullet that from valve body, gets into flow to periphery and evenly distributes; In the middle of adopting is conical reflector, makes bullet stream be mapped to the conical surface of reflector, and vertical reflection goes out valve body, reaches the purpose of axially spraying to the part bore area.In sum, this shot-peening nozzle adopts endoporus drainage bullet, the refraction of conical surface water conservancy diversion, and not only nozzle and part need not rotate, and bullet circumferentially sprays the part bore area, and jet face is even, and efficient is high, quality is good, and the while wearability of nozzle is good, long service life.

Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
As illustrated in fig. 1 and 2, a kind of novel shot-peening nozzle, it is characterized in that: the endoporus at valve body 1 is provided with boss; Boss is provided with baffle 3, and the left side of baffle 3 is provided with shunting cone 2, and the left end of shunting cone 2 is conical; The right side has cavity; The right side of baffle 3 is provided with reflector 4, and the centre of reflector 4 is conical, and shunting cone 2, baffle 3 are connected through screw 5 with reflector 4 jointly.
The cavity on described baffle 3 right sides is 3～5 passages of circle distribution.
During use, the left side of valve body 1 is installed on the compressed air shotblasting machine, high speed bullet stream flows in the cavity passage of baffle along the taper shape of shunting cone, and reflexes to the outside metal parts inner surface of valve body 1 along reflector 4.
