Hereinafter, with reference to the above description, a description will be given of how to perform the polishing process:
(1) before the equipment enters the special-shaped pipe, the electromagnetic component 4 and the electromagnetic component configured on the surface of the cylinder body 22 are in a power-on state, and based on the power-on state, the magnetic pole 55 is tightly attached to one side of the sleeve 54 with the hole under the guidance of strong magnetic attraction, and the polishing medium is firmly attached to the surface of the cylinder body 22;
(2) defining the specific position of the inner surface to be polished in the special-shaped pipe to ensure that the specific position is positioned between the air bags 51, then guiding airflow into the air bags 51 from the shaft tube 3, and expanding the air bags 51 in the special-shaped pipe so as to ensure that the area framed by the air bags 51 is in a closed state when the outer surface of the air bags 51 completely contacts the inner surface of the special-shaped pipe;
(3) after the position is clear, the current direction of the electromagnetic part 4 is changed, so that the magnetic pole 55 originally attached to one side of the sleeve pipe with the hole 54 and the electromagnetic part 4 repel each other and move towards the position of the medium cylinder positioning plate 6, and during the movement, the poking rod 13 is extruded, so that the support rod 12 connected with the poking rod 13 is bent outwards relative to the cylinder body 22, and the plugging rod 11 tightly installed at the slot 21 is moved out of the slot 21;
(4) when the electromagnetic component 4 changes the current direction, the electromagnetic component is powered off, after the power is off, the polishing medium in the cylinder body 22 flows out from the open slot 21 under the action of gravity, and the polishing position is polished by continuously contacting the position to be polished during flowing out;
(5) the electromagnetic component 4 is reset to the initial current direction, the slotting control rod piece 1 is bent and erected again, the electromagnetic component is electrified, so that the polishing medium in the closed area is adsorbed on the outer surface of the cylinder body 22, then the current direction of the electromagnetic component 4 is changed again, the electromagnetic component is powered off, and the polishing medium on the outer surface of the cylinder body 22 is contacted with the inner surface of the special-shaped pipe again;
(6) the above processes are repeated, and the inner surface of the special-shaped pipe in the closed area is continuously and effectively polished.
It should be noted that, in the step (5), when the current direction of the electromagnetic component 4 is changed again, the function of the slot control rod 1 is not to control the opening or closing of the slot 21, but to express the accumulated kinetic energy when the electromagnetic component is converted from vertical to bending in the polishing medium, so that the polishing medium is accelerated in the closed area, i.e. the polishing medium contacts the inner surface of the special-shaped pipe material at a better terminal speed, so as to obtain a more sufficient polishing effect, thereby greatly shortening the polishing time.
After polishing, the electromagnetic component of the barrel body 22 must be in an energized state, i.e., in an energized state, such that the polishing medium and the debris within the profiled tubing (metal tubing debris that is magnetically attracted to the electromagnetic component) are attracted to the surface of the barrel body 22 to maintain the polished profiled tubing in a relatively clean state after the polishing apparatus is removed.
Further, the position to be polished is located below the barrel body 22, the best polishing effect can be obtained, and certainly, in order to improve the polishing effect deeply, the irregular pipe can be continuously turned over through polishing, so that the polishing medium in the irregular pipe can contact the inner surface of the irregular pipe in a defined interval comprehensively, and the more sufficient polishing effect can be obtained.
The foregoing shows and describes the general principles, principal features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention, and that various changes and modifications may be made without departing from the spirit and scope of the present invention, which fall within the scope of the claimed invention.
