Buffer spray gun assembly

Abstract

The invention relates to a buffer spray gun assembly, including a nozzle connecting sleeve, a spray sleeve, a nozzle locking sleeve, a buffer joint and a nozzle. The spray sleeve is arranged in the nozzle connecting sleeve, and the rear end of the nozzle connecting sleeve is provided with an interface for connecting steel shot input pipes , the front end of the nozzle connection sleeve is connected to the nozzle lock sleeve, the nozzle is placed in the inner cavity of the nozzle lock sleeve, and a buffer joint is sandwiched between the rear end surface of the nozzle and the front surface of the spray sleeve, and the spray sleeve, buffer joint and nozzle The center of each center is provided with a central through hole, and the inner diameters of each central through hole are the same and communicated coaxially to form a steel shot channel. The steel shot channel is connected to the nozzle at the front center of the nozzle locking sleeve. The invention has a reasonable structure, and because a buffering and shock-absorbing structure is designed inside, it can effectively reduce the amount of mutual wear and prolong the service life of the internal assembly parts of the spray gun assembly.

Description

technical field [0001] The invention relates to the improvement of a spray gun device of a shot blasting machine, in particular to a buffer spray gun assembly, which belongs to the technical field of shot peening intensive cleaning. Background technique [0002] Shot peening is a surface treatment process widely used at present. The high-speed shot flow produced by shot peening hits the surface of metal parts and effectively improves the microstructure. It produces high surface residual compressive stress on the surface of metal parts. The residual compressive stress can be Offset the tensile stress of the metal parts in the alternating force movement that causes the fatigue damage of the components, thereby greatly improving the fatigue life of the metal parts and improving the performance of various mechanical equipment. [0003] In order to ensure that the shot peening effect reaches the standard, the flow rate of the steel shot during the shot peening process must be con...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure that the shot peening effect reaches the standard, the flow rate of the steel shot during the shot peening process must be continuous, uniform and stable. However, when the spray gun on the existing shot peening equipment sprays the steel shot, the impact of the strong airflow causes the steel shot to vibrate violently in the spray gun , the steel shot flow is unstable and uneven, and it will make the spray gun vibrate, which is not easy to control, thus affecting the treatment effect
