Description

Technical Field

[0001] The utility model relates to the technical field of a rear flushing structure of a diameter expander, in particular to an improved rear flushing nozzle of a diameter expander. Background Art

[0002] After the steel pipe is mechanically expanded by a diameter expander, its outer and inner walls need to be flushed, mainly to remove the lubricating oil sprayed on the inner wall of the steel pipe during expansion. At present, the flushing method for the inner wall of the steel pipe is to penetrate the flushing nozzle into the steel pipe and then spray the emulsion to flush the inner wall of the steel pipe. Figure 1 Since only emulsion needs to be delivered, the existing flushing nozzle is mainly a single-channel cylindrical nozzle, which has a plurality of spray holes 2 connected to the water channel distributed on the cylindrical surface of the nozzle 1, and the emulsion input into the flushing nozzle water channel can be sprayed out from the spray holes 2 to flush the inner wall of the steel pipe. After use, it was found that the effect of flushing with only emulsion is not good, and the emulsion combined with clean water can achieve a better cleaning effect, but the single-channel structure of the existing flushing nozzle cannot realize the simultaneous delivery and spraying of emulsion and clean water.
