7' When performing polishing, replace the abrasive material that has reached the end of its life.
This invention relates to a method for electrolytic composite polishing of a strip, which can be carried out without stopping the transportation of the strip.

In general, in electrolytic composite polishing that combines the polishing action of electrolysis and the abrasive action of an abrasive, if the strip is continuously conveyed and polished for a long time, the abrasive will be consumed and it will be necessary to replace the abrasive. There is.

However, when the conveyance of the strip is stopped when replacing the abrasive,
Work efficiency will decrease significantly. This invention has been made with the above points in mind, and will now be described in detail with reference to drawings showing one embodiment thereof. In the drawing, 1 is a polishing table, 2 is a strip of the object to be polished, which is conveyed at a constant speed from left to right on the polishing table 1, and 3 is the polishing table 1.
4 is a two-slide horizontal slide bar formed laterally on the pedestal 3; 5 is a vertical holding plate; 6 is a holder integrally formed on the back side of the holding plate 5. The holding plate 5 is slidably fitted onto the horizontal slide bar 4 and is movable in the horizontal direction along the horizontal slide bar 4.

7 is a hydraulic horizontal cylinder supported by the pedestal 3; 8 is a piston rod of the horizontal cylinder 1;
Its tip is connected to the right end of the holding plate 5, and as the piston rod 8 moves due to the operation of the horizontal cylinder 7, the holding plate 5 slides laterally along the horizontal sliding rod 4, thereby forming a horizontal sliding mechanism. has been done.

Reference numeral 9 designates two vertical slide rods formed in the vertical direction on the front surface of the holding plate, 10 represents an electrolytic composite polishing tool, and 11 represents a holder formed on the back surface of the tool 10, which slides into the vertical slide rod 9. , the tool 10 is freely movable in the vertical direction along the vertical slide rod 9.

12 is an upper and lower cylinder supported by the holding plate 5; 13 is a piston rod of the upper and lower cylinder 12, the tip of which is connected to the tool 10, and the tool 10 is moved up and down by movement of the piston rod 13 by the operation of the upper and lower cylinders 12; It slides in the vertical direction along the slide rod 9, and a vertical slide mechanism is constituted by the above.

14 is a rotating shaft introduced downward from the tool 10, and is rotated by a drive mechanism within the tool 10.

Reference numeral 15 denotes a polishing head attached to the tip of the rotating shaft 14, which includes electrodes 17 formed radially on the lower surface of the disk 16, and a disk abrasive material 18 attached to the lower surfaces of the disk 16 and the electrodes 17. It is composed of.

Then, the abrasive material 18 is brought into contact with the strip plate 2 with a predetermined pressing force, and the electrolytic solution from the tool 10 passes through the center hole of the rotating shaft 14 and the center hole of the disc 16, and the electrolyte is brought into contact with the electrode 17 and the strip plate 2. The polishing head 15 is rotated by the rotating shaft 14, and the electrode 17 is supplied with power from the tool 10, and the strip plate 2 is supplied with power from the polishing table 1! As a result, the polishing action by electrolysis and the scratching action by the abrasive material 18 are combined, and the band plate 2 is polished. Then, as shown in FIG. 1, in a state where the strip plate 2 is continuously conveyed to the right and the polishing head 15 is performing electrolytic composite polishing at the first position A shown in the figure, the polishing When the material 18 is worn out due to long-term use and reaches the end of its service life, the upper and lower cylinders 12 are activated to move the polishing head 15 upward together with the tool 10, the rotation of the polishing head 15 is stopped, and the abrasive material 18 is replaced with a new abrasive material. Exchange it for 18. Next, the horizontal cylinder 7 is actuated to rapidly move the polishing head 15 together with the holding plate 5 to the second position B shown in the figure, faster than the transport speed of the strip plate 2, and the upper and lower cylinders 12 are actuated to move the polishing head 15 to the second position B shown in the figure.
, and start polishing again at the second position B. Here, the length of the first position A and the second position B is the length that the strip plate 2 is conveyed during the time required for exchanging the abrasive material 18 and moving the polishing head upward, downward, and horizontally. This is the length plus a slight overlap.

Next, the horizontal cylinder 7 is operated to move the polishing head 15 from the second position B to the first position A within the life time of the abrasive material 18.
When the abrasive material 18 reaches the end of its life at the first position A, the polishing head 15 is moved upward again and the abrasive material 18 is replaced as described above. In the above description, the abrasive material 18 is replaced at the first position A, but it goes without saying that it may be replaced at the second position B.

As described above, according to the electrolytic composite polishing method for strips of the present invention, it is possible to replace the worn out abrasive material without stopping the strip being conveyed, improving work efficiency, and reducing the amount of abrasive material used. There is no need to prepare a preliminary polishing head for replacement.
