Background
At present, the metal pipe polishing machine tool commonly used for polishing the inner wall of a metal pipe fixes the metal pipe on the machine tool, a motor provides power, a polishing rod extends into the metal pipe to drive a thousand-impeller or a sand belt wheel to rotate at a high speed, polishing is carried out along with the rotation of the steel pipe, and the polishing rod slowly advances while rotating.
This process has the following disadvantages:
(1) the metal pipe is integrally processed, and when some metal pipes with longer lengths are processed, the length of a machine table is required to be very long and needs to exceed the length of the metal pipe to be processed, so that the whole machine table has a very long structure, large space is required, materials are consumed, the machine table is heavy, and the cost is high;
(2) the metal pipe polishing machine table adopts a grinding wheel (abrasive cloth) to rotate at a high speed for polishing, a rotating shaft which needs to be stretched out when a metal pipe with a long length is processed is very long, vibration is easy to generate, and the vibration amplitude is large, so that the friction noise between the grinding wheel and the inner wall of the metal pipe is very large;
(3) the inner wall of the metal tube is ground by the rotation of the shaft of the grinding wheel (abrasive cloth) at a high speed, and the grinding wheel (abrasive cloth) forms polishing marks along the inner wall of the metal tube. The fluid in the metal pipe flows through the metal pipe along the axial direction, the flow direction of the fluid is just vertical to the polishing mark of the metal pipe, so that the resistance of the fluid during fluid channeling is caused, the flow speed of the fluid is reduced, and the working benefit is further reduced;
(4) the mechanical polishing rotating shaft needs to be matched with the length of the metal pipe, so that the mechanical polishing rotating shaft has a long length. When the rotating shaft gradually moves for a distance, the rotating shaft naturally has a sagging amplitude due to overlong length, so that a grinding wheel (abrasive cloth) generates eccentric operation on the inner wall of the metal pipe, the grinding is light and heavy, the precision of the inner wall of the metal pipe is inconsistent, the product quality is seriously influenced, and the rotating shaft has large torque and high manufacturing requirement and cost due to the long length;
(5) the machine tool has long time consumption and low economic efficiency when used for processing the inner wall of the metal pipe.
