[0026] Working principle:

[0027] The operator places the sheet material on the workbench 5 and controls the extension end of the hydraulic cylinder 10 to extend and drive the clamping plate 11 to move inward. After the clamping plate 11 contacts the sheet material, it presses against and fixes it, preparing for the subsequent cutting of the sheet material.

[0028] Protective measures during sheet metal cutting:

[0029] When cutting sheet metal, molten slag will be generated. Connecting the external power supply to motor 201 starts the motor, causing its output shaft to rotate and drive the first gear 202 to rotate. The first gear 202 then drives the second gear 203 to rotate in the opposite direction. Simultaneously, the rotation of the first and second gears 202 and 203 drives the rotating rods 204 on both sides to rotate in the opposite direction. The rotation of the rotating rods 204 also drives the transparent protective plate 205 to rotate synchronously. The movement of the transparent protective plate 205 simultaneously drives the magnetic strips 206 to move synchronously. When the transparent protective plate 205 has rotated 90°, the magnetic strips 206 on both sides adhere tightly under the influence of magnetism, stopping the rotation of the motor 201's output shaft and preventing molten slag generated during subsequent sheet metal cutting from splashing onto the operator. After the sheet metal cutting is completed, the above process can be reversed to complete the protection process during sheet metal cutting.

[0030] Laser cutting process for sheet metal:

[0031] Once the sheet material to be laser-cut is placed on the surface of the worktable 5 and fixed in place, the operator controls the main body 8 of the laser cutting machine through the control terminal according to the product size and model, ensuring that the focus of the laser beam of the laser cutting head 306 is aligned with the processing point of the sheet material. The main body 8 of the laser cutting machine is started to control the laser cutting head 306 to perform laser cutting on the sheet material. After the cutting is completed, the main body 8 of the laser cutting machine and the laser cutting head 306 are reset to complete the laser cutting process of the sheet material. The working principle of the main body 8 of the laser cutting machine is consistent with the working principle in the authorization announcement number "CN 209986414 U".

[0032] The process of adjusting the angle of the laser cutting head:

[0033] When the angle of the laser cutting head needs to be adjusted, the operator turns the bolt 303 in the opposite direction, causing the rubber pad 304 at the end of the bolt 303 to move away from the steering ball 302, thus no longer fixing the steering ball 302. After the operator rotates the laser cutting head 306 to adjust the appropriate angle, the operator turns the bolt 303 again, causing the bolt 303 to drive the rubber pad 304 into the fixing block 301. This causes the rubber pad 304 to press against the steering ball 302, fixing the position of the steering ball 302, and then fixing the position of the laser cutting head 306, thus completing the angle adjustment process of the laser cutting head.

[0034] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
