The laser beam itself is not affected by the gas, it is responsible for effectively burning, melting or vaporizing the material, and the gas blows away the various debris generated in the process, thereby ensuring high-quality cutting edges. Laser cutting can also be used for welding and etching. Laser cutting machines are required for processing when producing aluminum alloy doors and windows.

[0046] Working principle:

[0047] When using a laser cutting machine to cut aluminum alloy doors and windows:

[0048] Fixation process:

[0049] The aluminum alloy doors and windows are placed on the surface of the support plate 6, and the cylinder 201 is controlled to work, so that the telescopic end of the cylinder 201 is shortened and the bent plate 205 is driven to move through the connecting plate 204, so that the bent plate 205 can drive the groove rod 206 to move synchronously through the cylinder 209, so that the groove rod 206 can drive the pressing plate 10 to press against the aluminum alloy doors and windows, so that the position of the aluminum alloy doors and windows is fixed. When it is necessary to fix the aluminum alloy doors and windows of different thicknesses, the operator pulls the handle 203 so that the handle 203 can drive the insertion rods 208 on both sides to move synchronously, so that the two springs 207 are stretched. At the same time, the operator pulls the groove rod 206 to rise or fall to a suitable height, and then releases the handle 203. Under the action of the springs 207 on both sides, the insertion rod 208 can be driven to engage with the groove rod 206 again, so that the height of the pressing plate 10 is adjusted and the position is fixed.

[0050] Limiting process:

[0051] When placing aluminum alloy doors and windows, it is necessary to make one side of the aluminum alloy doors and windows fit with the push plate 801, and at the same time, align the edge of the aluminum alloy door and window close to the laser cutting machine body 11 with the edge of the support plate 6 to complete the limiting of the aluminum alloy door and window. When limiting aluminum alloy doors and windows of different specifications, the operator rotates the bolt 804 so that the bolt 804 moves upward and no longer engages with the groove on the surface of the support plate 6. The operator pushes the push plate 801 so that the push plate 801 limits the position of the aluminum alloy door and window close to the pressure plate 10 to always be the same. At the same time, the operator rotates the bolt 804 in the opposite direction so that the bolt 804 engages with the groove on the surface of the support plate 6 again, so that the position of the push plate 801 is fixed, and the limiting of aluminum alloy doors and windows of more specifications is completed.

[0052] Feeding and cutting process:

[0053] The power device inside the base 1 is controlled to work, so that the power device inside the base 1 on both sides can drive the slide plate 7 to move (the power device can be a motor driving the lead screw to drive the slide plate 7 to move), and the slide plate 7 can drive the support plate 6 to move synchronously, so that the support plate 6 can drive the aluminum alloy door and window to move synchronously, so that the aluminum alloy door and window can move to the bottom of the laser cutting machine body 11 for cutting. When the length of the aluminum alloy door and window is long, the slide plate 7 moves to the limit position, and the aluminum alloy door and window still cannot be completely transported under the laser cutting machine body 11. The motor 901 is controlled to work so that the motor 901 The output shaft rotates to drive the lead screw 907 to rotate synchronously, so that the lead screw 907 can drive the threaded seat 906 to move, and the threaded seat 906 can drive the support plate 6 to move, so that the support plate 6 can drive the sliding bars 17 on both sides to move synchronously through the semicircular blocks 16 on both sides, so that the sliding bars 17 on both sides can slide under the support of the support blocks 18 on both sides, and at the same time, with the support of the rollers 904 on both sides, the movement of the support plate 6 can be more stable, so that the support plate 6 can continue to move when the slide plate 7 moves to the limit, so that the aluminum alloy frame can continue to move under the laser cutting machine body 11, so that the aluminum alloy frame can be completely cut.
