Problems solved by technology
At present, the nozzles of most spray guns on the market lack airflow control devices, the air pressure exhausts quickly during work, cannot obtain continuous sandblasting pressure, and will lead to a decrease in the roughness of the processed surface, affecting the wear resistance of the workpiece and the stability of the fit , fatigue strength, etc.

Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.
[0025] combine figure 1 Shown, a kind of shot-peening spray gun device comprises nozzle 5, air inlet pipe 1 and shot-peening inlet pipe 2, and described nozzle 5 top has two openings, and air inlet pipe 1 and shot-peening inlet pipe 2 are threaded respectively on two sides. The air inlet pipe 1 and the shot blasting inlet pipe 2 are inserted into the inlet of the nozzle 5, and the deflector 3 is installed at the outlet of the nozzle 5 through countersunk screws. The deflector 3 is a curved surface or an arc shape or a conical surface. The function of the deflector 3 is that when the nozzle is close to a certain distance from the shot blasting workpiece, due to the existence of the deflector 3, the shot blasting can be made to pass through the deflector. 3 Perform seconda...

The invention provides a blast shot spray gun device. The blast shot spray gun device comprises a nozzle, an air inlet pipe and a blast shot inlet pipe, the air inlet pipe and the blast shot inlet pipe are inserted into a nozzle inlet, a flow guide plate is arranged on a nozzle outlet, the flow guide plate is in a curved face or arc shape, and the reflection frequency of shot steel shots or steelsand is increased; the flow guide plate is a conical face, the center line of the conical face coincides with the center line of the nozzle outlet, the taper of the conical face of the conical flow guide plate ranges from 1 to 3 degrees, the proportion of the bottom face area of the conical flow guide plate to the area of the cross section of the nozzle outlet is 30:1-50:1, the length of the air inlet pipe inserted into the nozzle is smaller than the length of the blast shot inlet pipe inserted in the nozzle, and air pressure losses are avoided. The grinding frequency in unit time can be increased, the air pressure failure speed can be controlled, the machining efficiency is improved, and the effective jetting strength can be effectively improved.
Description
technical field [0001] The invention relates to the field of sandblasting and shot peening, in particular to a shot blasting spray gun device. Background technique [0002] Shot peening is a surface strengthening process widely used in factories, that is, a cold working process that bombards the surface of the workpiece with pellets and implants residual compressive stress to improve the fatigue strength of the workpiece. It is widely used to improve the mechanical strength of parts, as well as wear resistance, fatigue resistance and corrosion resistance. Shot peening is a surface strengthening process widely used in factories. Its equipment is simple, low in cost, not limited by the shape and position of the workpiece, and easy to operate. It can also be used for surface matting, descaling and eliminating residual stress of casting, forging and welding parts. The spray gun is one of the important parts of the sandblasting machine, and its quality affects the processing qu...
