が従来性われている。The method for marking the upper surface of the piston ring is to perform various surface treatments such as Cr plating, iron plating, nitriding, phosphorous salt coating, etc., and then mark the piston ring as shown in Figure 2. A conventional method is to send the ring 1 to a predetermined position on the positioning device 22 using a bushing 21, fix it, and stamp the ring 1 at the marking position of the upper surface mating opening 23 using a marking device.

り改善することはできなかった。In the conventional marking method for the upper surface of a piston ring, the piston ring is stopped at a predetermined position and is engraved in one series, so in order to make the markings visually readable,
It must be engraved to a depth of 0.03- or more. If the engraving depth is increased, curling will occur in proportion to the depth,
- There was a problem that the flatness of the stamped surface was impaired. Also,
Since it is a series of stamping operations, there is a problem in that productivity is low. It was not possible to improve the indistinctness and flatness of the stamp by various surface treatments.

業を繰返しピストンリングに連続的に刻印をしていく。The mirror 6b is linked to a computer (not shown) and moves in accordance with the characters and figures engraved at the marking position 8. During this marking of the piston ring 1', a new piston ring 1 is placed on the positioning device 3, completing its preparation for receiving the marking described above. These steps are repeated to continuously mark the piston ring.
