[0032] When laser cutting of metal plates is required for metal cutting, this device can be used. Make the machine tool 1 contact the ground, and then inject coolant or cold water into the cooling frame 11 from the water inlet and outlet 12. The cooling frame 11 is made of copper alloy, having good hardness, strength and high temperature resistance. Then use a plug to block the water inlet and outlet 12, and then pull the sliding frame 4 along the slide rail 3 out by the handle. The slide rails 3 are all U-shaped, facilitating the movement of the sliding frame 4. Then place the metal plate on the adjusting plate 10, and then start the first motor 5. Drive the bevel gear 6 to rotate through the first motor 5. The bevel gears 6 mesh with each other to make the bidirectional lead screw 7 rotate. Under the action of the thread, make the clamping plate 8 move along the sliding frame 4 to contact and clamp the metal plate, so as to be able to center and clamp the metal plate for positioning, ensure the position of the metal plate, reduce the dimensional error caused by material movement, and improve the cutting accuracy. Then turn off the first motor 5. Subsequently, push the sliding frame 4 to move back to its original position in the reverse direction by the handle, and then start the electric push rod 9. Drive the adjusting plate 10 to move through the electric push rod 9 to make the plate move. After adjusting to a suitable height, turn off the electric push rod 9. Then start the first trackless cylinder 101 to make the slider on the first trackless cylinder 101 move, and then drive the sliding block 102 to move. After moving to a suitable position, turn off the first trackless cylinder 101. Then start the second trackless cylinder 103 to make the slider on the second trackless cylinder 103 move, so that the laser cutting instrument 2 moves. After moving to a suitable position, start the laser cutting instrument 2 to cut the metal plate, so as to be able to adjust the position of the laser cutting instrument 2 and the height of the metal plate to perform laser cutting on the metal plate, facilitating the cutting of plates with different thicknesses, and improving the versatility and flexibility of this device. During the cutting process, cool and lower the temperature of the laser cutting instrument 2 through the coolant or cold water in the cooling frame 11. At the same time, select a suitable auxiliary gas according to the metal material. There are three different gases in the gas storage cylinder 13, namely oxygen, nitrogen and argon. Then start the second motor 18 on the fixing member 15. Drive the gear to rotate through the second motor 18. The gear meshes with the toothed ring to make the rotating cylinder 17 rotate, so that the holes on the rotating cylinder 17 rotate to the positions of the air outlet holes on the communication block 16 corresponding to the gases. Then turn off the second motor 18. Then make the gas in the corresponding gas storage cylinder 13 enter the connecting pipe 14, and then discharge from the air outlet hole into the air inlet frame 20, and then flow into the air injection pipe 21 and spray out for use. By contacting the laser cutting instrument 2 and the plate with oxygen, a large amount of heat is released for cooling. By spraying nitrogen for cooling and removing molten metal, a cutting edge without oxidation and with high surface finish is obtained. By using argon to prevent the metal from oxidizing at high temperature,Furthermore, by blowing away the molten slag and smoke generated during the cutting process with different gases, it is possible to select a suitable gas for treatment according to different metal materials during cutting and at the same time cool and protect the laser cutting instrument 2, improve the cutting quality and efficiency, prevent damage, extend the service life, and make it convenient to use. After the cutting is completed, turn off the laser cutting instrument 2, and then reverse the operation of the electric push rod 9 to make the adjusting plate 10 move backward and reset. Then turn off the electric push rod 9, then pull out the sliding frame 4 through the handle, and then reverse the operation of the first motor 5 to make the bevel gear 6 rotate in the reverse direction. The bevel gears 6 mesh with each other and move, making the bidirectional lead screw 7 rotate in the reverse direction. Under the action of the thread, the clamping plate 8 moves backward and resets. Then turn off the first motor 5, and then remove the metal plate, so that the position of the sliding frame 4 can be adjusted to load and unload the metal plate, saving time, reducing the difficulty of manual handling, and improving the operation convenience. Then place a new metal plate on the adjusting plate 10 and repeat the above operation to continue cutting the plate until the plate cutting is completed.
