Description

Technical Field

[0001] The invention relates to the technical field of shot peening equipment, in particular to an inner diameter shot peening circulation system. Background Art

[0002] Metal pipe fittings, especially large metal pipe fittings, play an indispensable role in the field of engineering technology and are widely used in the transportation of fluids such as oil, natural gas, water, and steam. Since the pipe fittings cast by foundries are relatively rough, and some parts even have metal and various residues, it is necessary to clean the outer and inner surfaces of the metal pipe fittings, otherwise it will affect the normal use of the metal pipe fittings. The outer surface is relatively easy to handle because it is exposed to the outside, but the inner surface is not so easy to handle. For some special industries, higher requirements are placed on the inner surface roughness of metal pipes. The quality of the inner surface roughness directly affects the fluid delivery effect. In this case, the inner surface of the metal pipe needs to be polished and ground. During the polishing process, due to the different lengths of the pipes, the traditional shot peening equipment cannot achieve uniform and complete grinding of the inside of the pipes. This requires the use of a shot peening gun with a certain length for grinding. During the shot peening process, how to improve the stability of the shot peening gun, and be able to grind the inside of the pipe in all directions, how to achieve continuous grinding after grinding, and make full use of the grinding shot to grind the workpiece, therefore, an inner diameter shot peening circulation system is required. Summary of the invention
