As shown in 705, the transverse direction is performed in the + X direction or the -X direction.

As shown in FIG. 4 (a), when the U servo motor 503 performs forward and reverse rotation, the pipe drive unit 5 rotates the drive shaft worm gear 508 coupled by the U servo motor 503 and the coupling 518. As the drive shaft 504 rotates, and the drive gear 506 rotates in accordance with the rotation of the drive shaft 504, the drive shaft rotating means 507 also rotates so that the pipe 501 connected thereto + Rotation in the U direction or -U direction, while the driven shaft worm gear 508 and the driven shaft worm gear 509 is also rotated to rotate the driven shaft 510, the rotation of the driven shaft 510 As the driven shaft gear 511 rotates accordingly, the driven shaft rotating means 512 also rotates, and the pipe 501 is rotated by interlocking with the drive shaft rotating means 507. Pressing a button (not shown) on the pipe operation panel 502 causes the U servo motor 503 to stop. The rotation, and thus there is a pipe to a 501 rotation as described above, which is used for, setting the time of preparation of the pipe and the extraction pipe.

As shown in FIG. 4 (b), the pipe supporting part 6 is always in an idling state so that the pipe supporting part 6 rotates and stops in conjunction with the pipe 501 while the pipe 501 rotates and stops. The pipe 501 is supported and maintained in balance, and the pipe support 6 is disposed below the pipe support 6 so as to be properly spaced from the pipe drive 5 described above according to the length of the pipe 501. The roller 604 slides on the rail 514, which is enabled by manual operation.

Next, referring to the process of cutting the plate 401, as shown in Figs. 2 and 3, the plate 401 is placed on the flat work table 4, and the desired shape program is input to the CNC controller 1. Then, when starting, the heat source (not shown) is ejected from the torch 303, and as described above, the torch 303 is operated simultaneously or separately in the X direction and the Y direction to draw a desired shape of the trajectory. 401 is cut | disconnected to desired shape by the heat source (not shown) of the torch 303. FIG.

Looking at the process of cutting for the processing of the circular pipe 501, as shown in Fig. 5, the pipe 501 to be cut is placed on the pipe driving part 5 and the pipe support 6, and the desired program is CNC. When inputted to the controller 1 and started, the heat source (not shown) of the torch 303 is ejected and the pipe 501 rotates in the + U or -U direction as described above, and at the same time the torch 303 In addition, the cutting is made by operating in the + X or -X direction.

Next, as an embodiment of the present invention, the rotating sphere 9 is devised for smooth cutting of non-circular pipes, and L-shaped steels, H-shaped steels, etc. Referring to the cutting process of the square pipe 501a, as shown in FIGS. 6 and 7, a plurality of rotary holes 9 are clamped to the square pipe 501a to be cut, so that the pipe driving part 5 and the pipe support part 6 ), And control the pipe operating plate 502 to operate the button to rotate the square pipe 501a to be the starting position, which is because the outside shape of the square pipe 501a is not constant. After the program is input to the CNC controller 1 and started, the torch 303 lowers to the height of the cutting start point toward the square pipe 501a, and the torch 303 Heat source (axe U) is ejected to start the cutting operation. For example, if a square hole is machined in the square pipe 501a, the torch is operated by the operation of the X driving unit 7 and the Y driving unit 8 as described above. 303 is cut in (a) to (b) by starting in the -Y direction, cut in (b) to (c) by starting in the + X direction, and starting in + Y direction (c). ) Is cut from (d) to (x), and the cut is made from (d) to (a) by activating in the -X direction. The rectangular hole of the desired shape is cut, and then the torch 303 is raised The distance from the square pipe 501a is a proper distance, which is larger than the position of the end of the end of the torch 303 to be cut because the radius of the square pipe 501a rotates to the torch 303 when the square pipe 501a rotates. In order to prevent collision, it is necessary to cut another side again. In order to rotate the square pipe 501a in the -U or + U direction, the cutting operation is performed by the sequence of the program input to the CNC controller 1 in the above-described process. This is not only limited to the cutting of the square pipe, but also by changing the operation order of each part by a program or by changing the structure of the clamp 521 of the rotating hole 9 as described above in the part-specific configuration. It is possible to cut the section steel such as round pipe, L section steel and H section steel.

Next, as another embodiment of the present invention, the pipe 501 to be cut is devised to work when the longitudinal direction of the pipe 501 is placed perpendicular to the X direction and placed parallel to the Y direction As shown in FIG. 8 and FIG. 9, the cutting process may be performed on the pipe driving part 5 and the pipe support part 6. When placed in the engine, the desired program is input to the CNC controller 1, and then started. The heat source (not shown) of the torch 303 is ejected and the pipe 501 rotates in the + U or -U direction. At the same time, the torch 303 is also driven in the + Y or -Y direction so that the desired cutting is made.

As described above, the present invention, the X drive unit 7, the Y drive unit 8, the plate worktable 4, the pipe drive unit 5, the pipe support unit 6, the torch unit 3 And, by the rotary sphere (9) by the control of the CNC controller (1), by automating the batch processing of the steel, such as various pipes, plates and section steel, batch processing, eliminating the trouble of various cutting processes, cutting Increasing the accuracy of the dimensions and improving the work efficiency has a number of effects, such as manufacturing cost reduction and quality improvement.
