7. A self-cooling steel polisher apparatus as defined in claim 1 further comprising: the water spraying area of the clear water spray head (404) is located in the shielding range of the water baffle (405), and a liquid drainage bottom pipe (406) used for collecting liquid and metal powder mixture at the bottom of the lining frame (4) in a backflow mode is arranged at the bottom of the lining frame (4).
8. A self-cooling steel polishing method, characterized in that a self-cooling steel polishing device as claimed in any one of claims 1 to 7 is used, comprising the steps of: (1) before a steel piece (1) is sent into a region between polishing wheels (5) on two sides, an electromagnetic mechanism (11) is started to attract a magnetic suction disc (414), and a lining frame (4) and the polishing wheels (5) move inwards; secondly, pushing the side end of the steel piece (1) to the area between the polishing wheels (5) on the two sides, powering off the electromagnetic mechanism (11), enabling the polishing wheels (5) to move outwards, enabling the polishing wheels (5) to extrude the steel piece (1), and sensing and detecting the extrusion deformation distance of the tension spring (9) after the polishing wheels (5) extrude inwards by the photoelectric distance sensing module (10); thirdly, according to the extrusion deformation distance of the tension spring (9), the extrusion force between the polishing wheel (5) and the steel piece (1) is analyzed, and according to the polishing reference extrusion force preset by the system, the electromagnetic mechanism (11) is driven to attract the magnetic chuck (414) to a corresponding degree; (2) polishing, cleaning and cooling, namely polishing the steel part (1) by using a polishing wheel (5), starting a clear water spray head (404), an inclined air knife pipe (407), a low-position air outlet pipe (410) and a polishing liquid spray head (409), directly spraying a position area where bristles (402) are contacted with the polishing wheel (5) by using the clear water spray head (404), spraying and cleaning the surface of the polishing wheel (5), liquid attached to the bristles (402) and metal powder residues, and simultaneously cooling the polishing wheel (5) for the second time; secondly, a small amount of liquid and powder are remained on the surface of the polishing wheel (5), when the liquid and the powder pass through the inclined air knife pipes (407), the liquid and the powder are continuously blown downwards along the surface of the polishing wheel (5) by the inclined air knife pipes (407), and the liquid and powder mixture falling on the bottom of the lining frame (4) is blown to the position of the liquid drainage bottom pipe (406) by the low-position air outlet pipe (410) to be discharged; and thirdly, after the polishing wheel (5) passes through the inclined air knife pipe (407), the polishing liquid spray head (409) sprays polishing liquid to the position where polishing friction between the polishing wheel (5) and the steel piece (1) is about to occur.
