Abstract

The invention relates to the technical field of steel pipe expanding equipment, in particular to an after-washing device of an expanding machine. The after-washing device comprises a box body, a rotating shaft and a sprayer unit which are coaxially arranged. The box body is installed at the end of an after-washing cantilever of the expanding machine. One end of the rotating shaft is inserted in the box body and connected with a driving unit, and the other end of the rotating shaft is connected with the sprayer unit. The rotating shaft can rotate freely in the axial direction of the rotating shaft. The driving unit is used for driving the rotating shaft and the sprayer unit to rotate synchronously. The sprayer unit comprises a fixed piece and a plurality of nozzles which are evenly distributed on the periphery of the fixed piece. Water delivery channels which are communicated with the nozzles are formed in the rotating shaft and the fixed piece. A water injection cavity is formed in the box body, the water injection cavity is communicated with the water delivery channels, and the water injection cavity is communicated with a high-pressure water inlet pipe. By means of the after-washing device of the expanding machine, the problems that by the adoption of a fixed sprayer, residual oil stains exist on the inner wall of a washed steel pipe and the water utilization rate is low in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of steel pipe expanding equipment, in particular to a post-expanding machine flushing device, and more particularly to a post-expanding machine flushing device with a rotatable nozzle. Background technique [0002] After the steel pipe is mechanically expanded, due to the needs of subsequent processes, the emulsion sprayed on the inner wall of the steel pipe during diameter expansion and the oxide scale generated on the inner wall during diameter expansion must be removed. Impurities such as lubricating oil remaining after diameter expansion are cleaned. [0003] At present, there are fewer flushing devices after expanding machines in China, and some processing plants clean them manually. The work efficiency of manual cleaning is low, the labor cost is high, and the cleaning quality cannot be guaranteed and unified. And a kind of flushing device in the prior art, its flushing nozzle is four fixed nozzles, ...
