The convex shaft 61 rotates through the circular plate 60, driving the T-shaped plate 62 to reciprocate. The reciprocating motion of the T-shaped plate 62 pumps the polishing liquid in the polishing box 37 into the working box 40 through the lower liquid pipe 38, and then squeezes and discharges it through the Y-shaped nozzle 41. The function of the pressure relief valve 42 on the Y-shaped nozzle 41 is that when the pressure reaches a certain level, it is discharged at multiple angles through the Y-shaped nozzle 41. The two ends of the Y-shaped nozzle 41 are respectively facing the side wall and the inner surface of the I-shaped steel, which is convenient for spraying the polishing liquid.

[0042] S3. After the initial processing of the "I-shaped" steel, it is necessary to flip it over and process the other side of the steel. At this time, the electric guide rod 8 is started to rotate the electric guide rod 8 out of the limit slot 7. The operator first releases the clamping state of the L-shaped plug plate 57 on the slot 58, and then turns the hand wheel 4 to drive the arc plate 3 to rotate as a whole on the surface of the C-shaped plate 2 through the connection of the cross plate 5. The pad 15 originally located on the top of the arc plate 3 is located below the arc plate 3 after rotating 180 degrees, supporting the flipped I-shaped steel. At this time, the linkage plate 9 moves as a whole to one side of the guide plate 6, and will not interfere with the rotating arc plate 3. The forward and reverse motor 12 can be started to reverse, and the flipped I-shaped steel can be polished again.

[0043] S4. When polishing the inner surface of the "I-shaped" steel of workpieces of different specifications, it is necessary to adjust the positions of multiple polishing circular plates 46. At this time, the operator keeps the inner polishing plate 23 stable with one hand and rotates the screw rod 54 with the other hand. The screw rod 54 rotates through the connecting plate 53 to change the position of the slide bar 51 in the sleeve 52. At this time, the slide bar 51 slides in the sleeve 52. After the position is changed, the position of multiple triangular plates 47 is driven to change, so that the push rod 44 slides on the inclined surface of the triangular plate 47. After adjusting the height, the position of multiple polishing circular plates 46 from the center of the inner polishing plate 23 is controlled to adapt to the height difference of the inner surfaces of workpieces of different specifications.

[0044] The working principle of the present invention is as follows: the I-shaped steel surface rust removal equipment and method, after the operator places the I-shaped steel material to be processed and rust removed on the pad 15, the third polishing disc 34 is in contact with the upper surface of the workpiece, and then the operator starts the forward and reverse motor 12, the output end of the forward and reverse motor 12 drives the U-shaped tube 17 to rotate, the rotation of the U-shaped tube 17 drives the driving disc 25 to rotate, the rotation of the U-shaped tube 17 drives the linkage shaft 24 to rotate, the rotation of the linkage shaft 24 drives the first polishing disc 18, the second polishing disc 20, the first thumb coupling 59 and the spur gear 21 to rotate, the spur gear 21 rotates and cooperates with the rack 22, so that the spur gear 21, under the support of a plurality of balls 64, drives the linkage plate 9 to slide on the surface of the guide plate 6, and the first gear 16 rotates to drive the second gear 10 to rotate The second gear 10 rotates to drive the third polishing disc 34 to rotate. The third polishing disc 34 rotates and contacts with the upper surface of the I-shaped steel to perform polishing and rust removal. When the U-shaped tube 17 rotates, it drives the driving disc 25 to rotate, changes the position of the driving disc 25, and drives the L-shaped piston plate 29 to reciprocate through the connecting shaft 26 and the connecting rod 28. In this process, the L-shaped piston plate 29 pushes the polishing liquid falling from the discharge hole 35 out of the discharge pipe 30 reciprocatingly. The polishing liquid dripping from the discharge pipe 30 flows into the multiple polishing holes 33 through the multiple guide grooves 32. The polishing liquid in the polishing holes 33 enters the lower surface of the third polishing disc 34 and cooperates with the third polishing disc 34 to perform polishing and rust removal. The linkage shaft 24 rotates to drive the first thumb coupling 59 and the second thumb coupling 3 6 rotates, the second thumb coupling 36 rotates through the sleeve 52 to drive the slide bar 51 and the inner throwing disc 23 to rotate, the rotation of the inner throwing disc 23 will drive the fourth polishing disc 43 and multiple polishing circular discs 46 to rotate, and perform polishing and rust removal operations. In this process, the second thumb coupling 36 will drive the driving disc 49 to rotate through the convex ball 48, and the convex ball 48 cooperates with multiple ball grooves 50. The driving disc 49 drives the convex shaft 61 located on the side connected to it to rotate, and the convex shaft 61 rotates through the circular plate 60 to drive the T-shaped plate 62 to reciprocate. The reciprocating motion of the T-shaped plate 62 pumps the polishing liquid in the polishing box 37 into the action box 40 through the lower liquid pipe 38, and then squeezes and discharges it through the Y-shaped nozzle 41. The function of the pressure relief valve 42 on the Y-shaped nozzle 41 is that when the pressure reaches a certain level After that, it is discharged at multiple angles through the Y-shaped nozzle 41. The two ends of the Y-shaped nozzle 41 are respectively facing the side wall and the inner surface of the I-shaped steel, which is convenient for spraying the polishing liquid and facilitating the subsequent polishing of the inner polishing disc 23. After the polishing of the I-shaped steel is completed, the operator can control to start the electric guide rod 8 so that the electric guide rod 8 rotates out of the limit groove 7. The operator first releases the clamping state of the L-shaped plug plate 57 on the slot 58, and then rotates the hand wheel 4. The arc plate 3 is driven to rotate as a whole on the surface of the C-shaped plate 2 through the connection of the cross plate 5. The I-shaped steel on the pad 15 is guided and clamped by a pair of electric guide rods 8, and then turned over and rotated 180 degrees, and then placed on the pad 15 originally located on the top of the arc plate 3. After the pad 15 originally located on the top of the arc plate 3 is rotated 180 degrees,Located below the arc plate 3, the I-shaped steel is supported after the flip. At this time, the linkage plate 9 moves as a whole to one side of the guide plate 6, and will not interfere with the rotating arc plate 3. After the rotation is completed, the forward and reverse motor 12 can be started to reverse, and the flipped I-shaped steel is polished again. When it is necessary to polish the inner surface of the I-shaped steel of different specifications, it is necessary to adjust the positions of multiple polishing circular discs 46 to meet the specifications of different I-shaped steels. At this time, the operator keeps the inner polishing disc 23 stable with one hand and rotates it with the other hand. The screw rod 54 rotates through the connecting plate 53 to change the position of the slide rod 51 in the sleeve 52. At this time, the slide rod 51 slides in the sleeve 52. After the position is changed, the position of multiple triangular plates 47 is driven to change, so that the push rod 44 slides on the inclined surface of the triangular plate 47. After adjusting the height, the position of multiple polishing circular plates 46 from the center of the inner polishing plate 23 is controlled to adapt to the height difference of the inner surface of workpieces of different specifications. With the above structure, multiple surfaces of "I-shaped" steel are automatically polished and rust-removed to improve efficiency.
