[Problem that the idea aims to solve]

As mentioned above, when only a needle marking head is installed as the marking means, the marking speed Although it is unavoidable that the cutting speed is slow, the score lines can be removed by cutting the steel plate with gas. There is no problem when cutting so that it is erased, but it is not a problem when cutting lines are erased. often remains on the surface of the steel plate even after the structure is completed. Therefore These remaining score lines are the same as surface scratches and can cause stress concentration and crevice corrosion. It is hard to say that this is a favorable state for creatures.

[0005] In addition, if only a thermal spray scribe head is installed as a scribing means, this thermal spray scribe will Unlike needle marks, they do not leave surface scratches, but the marks are thick and may be scratched as they are processed. It is not possible to ensure high precision, and extra machining work is required to compensate for this precision. However, there was a problem in that machining efficiency deteriorated.

Execute the ruler from the input data group. Select the data of the steel plate 5 to be processed, and manually align the origin of the NC mechanism. After that, the prescribed markings are made.

[0021] As mentioned above, needle markings generally have thin marking lines and can be written with high precision, but the speed is slow. , Thermal spray markings can be scored at high speed, but the marking lines are thick. This device Because of the characteristics of both scribing heads and the fact that they do not leave scratches on the structure, it is recommended to use both. It was designed to be separated. Therefore, relatively high accuracy is required among the marking data. The needle marking head 26 selects items that are removed during processing and items that are removed during processing. For the others, the thermal spray marking head 27 is selected. And this The origin alignment for the mounting positions of both heads can be done within the CNC rather than using mechanical mounting methods. Needless to say, it is automatically processed.

[0022] In the markings for the flange materials 1 and 2 shown in Fig. 1, the outline cutting position 6 and the hole drilling position are The position 8 is processed by the needle marking head 26, and the other web attachment positions 7 and diaphragm The attachment position 9 and the vertical rib attachment position 10 are processed by a thermal spray scribing head 27. .

[0023] During the scribing process with the needle scribing head 26, the other thermal spray scribing head 27 is connected to the cylinder 2. 9, and while the sprayed marking head 27 is processing the markings, the needle markings are The head 26 is retracted upward by the action of the cylinder 28. And all the outlines are completed Then, both the marking heads 26 and 27 are retracted upward and returned to the NC origin. Then, The cylinder 15 operates to move all the drive rollers 16 above the top surface of the marking plate 11. After the steel plate 5 is supported on the drive roller 16, the drive roller 16 is driven. The steel plate 5 is moved out of the system, and the state waits for input of the next marking command.
