Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims.

In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.

As shown in Fig. 1 to Fig. 3, the curved surface processing apparatus of the hull material according to the present invention includes a laser beam irradiation unit 100, a drive unit 200, and a controller 300.

First, the laser beam irradiation unit 100 irradiates the laser beam 120 through the injection hole 110 while moving along the reference line 11 of the material 10 for processing into a curved surface.

The material 10 may be a curved plate or the like for forming an outer surface of a ship, and the like, which has been conventionally bent through heat processing, uses a laser beam bending method.

To this end, the reference line 11 to which the laser beam 120 is irradiated may be marked on the upper surface of the material 10.

As described above, both ends of the material 10 are bent upward with respect to the reference line 11 of the material 10 to which the laser beam 120 is irradiated.

That is, the molten portion 12 formed along the reference line 11 by the laser beam 120 is the molten portion 12 is formed on the top of the material 10.

At this time, both ends of the material 10 are bent in the direction of the molten portion 12, the physical properties of which are relatively weakened.

In addition, since the laser beam 120 is irradiated with a narrow width, it is possible to reduce the deformation of the material 10 due to the thermal effect.

On the other hand, the laser beam irradiation unit 100 may be arranged in a plurality along the direction of the reference line 11 of the material 10.

That is, the laser beam irradiation unit 100 may selectively irradiate the laser beam 120 depending on the thickness or type of the material 10.

In addition, a power supply unit (not shown) for supplying power to the laser beam irradiation unit 100 may be provided.

The drive unit 200 selectively moves the laser beam irradiation unit 100 along the X axis, the Y axis, and the Z axis by supplying power from the power supply unit.

To this end, the driving unit 200 may be provided with an X-axis moving member 210, a Y-axis moving member 220, and a Z-axis moving member 230.

First, the X-axis moving member 210 may be installed on the upper end of the laser beam irradiation unit 100 to move the laser beam irradiation unit 100 on the X axis.

The Y-axis moving member 220 may be installed at the upper end of the X-axis moving member 210 to move the laser beam irradiator 100 along the Y-axis.

The Z-axis moving member 230 moves the X-axis moving member 210 and the Y-axis moving member 220 to the Z-axis to raise and lower the laser beam irradiation unit 100 to a predetermined height so as to be positioned at a predetermined height. Can be.

Alternatively, the driving unit 200 may be used in any manner as long as it can move the laser beam irradiation unit 100 in the X-axis, Y-axis, and Z-axis directions.

The controller 300 is for controlling the operation of the driving unit 200 and the laser beam irradiation unit 100, and the controller 300 may be preset with a reference irradiation value according to the bending angle of the material 10.

Here, the controller 300 may vary the irradiation value of the laser beam 120 of the laser beam irradiation unit 100 according to the bending angle of the material 10 to be gas cut.

In other words, by varying the laser beam 120 irradiation value, the deformation amount of the material 10 may be variously set, and thus, the processed form of the material 10 may be variously obtained.

In addition, the controller 300 may preset a reference movement speed value according to the bending angle of the material 10.

That is, the bending angle of the finished material 10 may vary depending on the depth of the molten portion 12.

For example, when the vertical depth of the molten portion 12 is equal to (a) as shown in FIG. 4A, the bending angle of the material 10 is increased by the shallowly formed molten portion 12.

Alternatively, when the vertical depth of the molten portion 12 is equal to (b) as in (B), the bending angle of the material 10 by the deeply formed molten portion 12 has a bending angle that is relative to that of (A). Becomes smaller.

Here, the controller 300 may vary the moving speed of the laser beam irradiation unit 100 according to the bending angle of the selected material 10.

In addition, the controller 300 may further be electrically connected to the distance sensor 400 for detecting the distance between the lower end of the laser beam irradiation unit 100 and the upper end of the material 10.

The distance sensor 400 transmits a distance detection signal to the controller 300 to maintain the lower end of the laser beam irradiator 100 and the upper end of the material 10 at a predetermined distance.

In addition, the input sensor 300 to detect the input of the raw material 10 may be further electrically connected to the controller 300.

The input detecting sensor 500 applies an input detecting signal to the controller 300 when the raw material 10 is detected to stop at the standby position.

In this case, the controller 300 may drive the driving unit 200 to irradiate the laser beam 120 while moving along the reference line 11 after the laser beam irradiation unit 100 descends.

Preferably, when the input detection sensor 500 detects the end of the material 10 stopped in the standby position, it may transmit a detection signal to the controller 300.

To this end, the controller 300 may be a computer numerical control (CNC) control method.

The controller 300 may further include a water cooling unit 600 for injecting cooling water into the molten portion 12 of the material 10 that is bent and formed by the laser beam irradiation unit 100.
