Abstract

PURPOSE:To grind and finely polish a worked material and obtain the product having high quality through the synergetic action of the rotary contact of the working members for a metal wire material (worked material) having a small diameter in reeled state and the transfer of the worked material. CONSTITUTION:A long worked material, e.g., a titanium alloy wire material is fitted, penetrating through the center part of a rotary frame 3 along the passing locus from the right to the left on the figure. Circular grindstones, i.e., working members 41 and 41' in discharge of role are mounted onto a shaft part 42, and the contact and the pressing pressure for the worked material are adjusted. Therefore, the working member 41 carries-out rough polishing, and the working member 41' carries-out fine polishing. After preparation is completed, the rotary frame 3 and the working members 41 and 41' are revolved, and the worked material is taken-up onto a taking-up reel. The rotary frame 3 revolves in the peripheral direction with respect to the worked material on the both base parts by the revolution of a driving wheel 38 because of a driving source 13 built into the base part 1. The working members 41 and 41' are revolved by the motors 45 and 45', and an air cylinder 52 drives a pressure adjusting lever 51 to adjust the pressing pressure of the working members 41 and 41' for the worked material. The worked material can be finely polished through the passing only in one time.

], 41', and adjust contact and suppression to the workpiece. Note that the workpiece is polished while passing to the right and to the left in Figure 1, so the workpiece 41 is in charge of rough polishing and the workpiece 41' is in charge of precision polishing. The material is wound on a reel - C. It is fed from the right side in the figure, and is taken up by the take-up reel to the left (I7), so the rotation direction of the processed material 4141' is counterclockwise in the figure. The lower stage rotates in the opening direction to polish the workpiece.

After the above preparations are completed, the rotary frame 3 and the workpiece 41, 41' are rotated, and winding of the workpiece by the take-up reel is started. The rotating frame 3 is a drive source 1 built into the base (A) 1.

Air is supplied from 4 to drive the pressure adjustment rod 51 to adjust the pressure of the workpieces 4 and 41' on the workpiece. The surface of the workpiece is polished by the workpiece 41, 41' while moving in the circumferential direction due to the rotation of the rotating frame 3, and in addition to this, the workpiece itself moves in the thrust direction. After phase opening, the surface of the workpiece can be precisely polished by passing through this polishing device only once, that is, by just one operation. However, in the explanation in J1, the wire rod has a circular cross-sectional shape, but if it is flat, the rotating frame should be fixed at a predetermined angle so that the surface of the workpiece corresponds to the workpiece. You can take advantage of this by doing this. Therefore, embodiments of the present invention have been described above.
The processed material in the example is 12-stage series (rough polishing and precision polishing), but this can be made into a multi-stage series to finish Japanese-made wire rods up to precision polishing in one operation, and give rotation to the processed material. Proposition 1 was changed without departing from the spirit of the present invention, such as replacing the motor device with belt transmission and installing it separately every two months (8), and the means for pressing the workpiece against the workpiece. There are things you can do freely.
