Abstract

The invention discloses a polishing device for the inner wall of a magnetic special-shaped tube. Two magnetic needle suspension collection and pumping components are installed in the polishing box. The special-shaped tube is rotatably installed between the two magnetic needle suspension collection and pumping components. The magnetic needle suspension is in the The magnetic needle suspension collects the flow between the pump out component and the inner cavity of the special-shaped tube; there are multiple sets of guide rails in the polishing box, and each set of guide rails is equipped with an electromagnetic coil assembly. The electromagnetic coil assembly is generated by the change of input current, voltage and current direction. The magnetic field distribution and magnetic field conversion frequency drive the magnetic needle in the magnetic needle suspension to impact the special-shaped tube at the required speed for polishing. The invention utilizes its unique magnetic field distribution to produce a strong and stable magnetic induction effect, so that the magnetic steel needle and the inner cavity of the special-shaped tube can be fully impacted and ground in all directions and from multiple angles, and quickly polished. After polishing, the surface can reach the level of the mirror surface without damage And the surface of the special-shaped tube, does not affect the precision of the special-shaped tube, and at the same time has a certain strengthening effect on the metal material special-shaped tube.

Description

technical field [0001] The invention belongs to the technical field of parts surface treatment, and relates to a polishing device, in particular to a polishing device for the inner wall of a magnetic special-shaped tube. Background technique [0002] The polishing of the inner wall of long tubes, bent tubes and special-shaped tubes made of metals such as gold, silver, copper, aluminum, zinc, magnesium, iron, stainless steel and non-metallic materials such as hard plastics has always been a major problem in surface treatment; It is difficult to polish the inner wall of long pipes, bent pipes and special-shaped pipes by mechanical means, using the relative movement of the grinding head and the inner wall of the pipe fitting. Treatment by chemical and electrochemical means will cause corrosion on the inner wall, uneven polishing at the bend, and chemical waste liquid, which may pollute the environment and be costly. Contents of the invention [0003] In view of the deficienc...
