[0024] In Embodiment 2, based on Embodiment 1, the electromagnetic control component 5 includes: an electromagnet 501 and a downward sliding block 502. The electromagnet 501 is fixedly mounted on the sliding mounting bracket 402; the downward sliding block 502 is slidably mounted on the sliding mounting bracket 402; the electromagnet 501 is aligned with the bottom of the downward sliding block 502; a spring is sleeved on the inner side of the bottom of the downward sliding block 502; the spring on the inner side of the bottom of the downward sliding block 502 is connected between the electromagnet 501 and the downward sliding block 502; the electromagnet 501 is used to magnetically attract the downward sliding block 502; the electromagnetic control component 5 also includes: an electromagnetic switch 503, which is fixedly mounted on the sliding mounting bracket 402. The device is equipped with an electromagnetic switch 503; the electromagnetic switch 503 is located above the lower sliding block 502; the top of the lower sliding block 502 is used to press and adhere the electromagnetic switch 503; the electromagnetic switch 503 is electrically connected to the laser cutting machine; the polarization safety component 6 includes: a polarization mounting cylinder 601 and a spiral guide wire 6011, the polarization mounting cylinder 601 is inserted into the insertion mounting plate 403; the polarization mounting cylinder 601 has a through hole in the middle; the spiral guide wire 6011 is fixedly embedded in the through hole in the middle of the polarization mounting cylinder 601, and the spiral guide wire 6011 is installed in a spiral shape; the polarization safety component 6 also includes: a conductive wire 602 and a spiral guide wire 601. Conductive wires 602 are fixedly installed at both ends, and each conductive wire 602 passes through a polarizing mounting cylinder 601. The two conductive wires 602 and the electromagnet 501 are connected in series with a power supply. A polarizing safety device 6 enables automatic polarization detection below the laser cutting head. Simultaneously, a spiral guide wire 6011, when the laser cutting head is normally emitting laser light, will not cause interference, but will automatically detect any polarization. Combined with an electromagnetic control device 5, this enables automatic shutdown protection of the laser cutting machine, preventing further damage to the sheet metal and ensuring cutting accuracy. While manual adjustments are necessary, the direct detection method using the spiral guide wire 6011 effectively ensures timely detection, avoiding the long cycle of manual polarization checks that could lead to excessive cutting deviations in sheet metal and increased economic losses. Furthermore, the direct shutdown control method further reduces the workload of staff, eliminating the need for frequent checks. The spiral structure of the 6011 guide wire ensures comprehensive polarization detection. When excessive polarization gradually occurs during the actual laser cutting process, the spiral guide wire 6011 will be cut, causing the electromagnet 501 to lose power and shut down the laser cutting machine.

[0025] The working principle of this embodiment is as follows: First, the laser cutting machine base is installed by bolts passing through bolt mounting holes 1011. Simultaneously, the cutting mounting cylinder 401 can be directly welded to the laser cutting head. Before actual cutting, the friction sliding frame 301 is pulled outwards. During this process, the tension spring 201 is stretched, the tension slider 202 moves outwards, and the tension elastic rope 203 is also elastically stretched, placing the plate material on a row of support blades 102. At this point, releasing the friction sliding frame 301 allows it to move under the elastic pull of the tension spring 201 and tension elastic rope 203, elastically clamping the plate material. Subsequent cutting can then proceed normally. The laser cutting head is positioned at the gantry... During the process of switching the cutting position by the moving structure drive, protective gas is supplied. The bellows 404 can be connected, and the protective gas of the laser cutting head can be introduced into the through hole in the middle of the polarizing mounting cylinder 601 for jet protection. After the cutting is completed, when the plate is removed, the friction sliding frame 301 can be automatically pulled back to its original position under the elastic pull of the tension spring 201 and the tension elastic rope 203. During the process, the elastic downward pressure of the downward spring 304 causes the downward pressure strip 302 to drive the grinding disc 303 to move down and fit against a row of support blades 102 for grinding and roughening treatment, so that the laser can diffusely reflect when it passes by again, preventing direct specular reflection from causing safety hazards, burning the plate, or directly reflecting and damaging the laser cutting head. If the polarization gradually exceeds the limit during the actual laser cutting process, the eccentric laser will directly cut the spiral guide wire 6011. Once the spiral guide wire 6011 is cut, the electromagnet 501 will lose power and will no longer magnetically attract the downward sliding block 502. Under the pressure of the spring inside the downward sliding block 502, the downward sliding block 502 will move upward to press the electromagnetic switch 503, controlling the laser cutting machine to stop. The automatic control completes the shutdown. The staff can then perform timely maintenance. After replacing the polarization fuse 6, the conductive wire 602 can be connected to the power supply and the electromagnet 501 through the plug, and it can be put into use again.
