[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The rotating sleeve drives the telescopic sleeve, the rotating ring and the workpiece after cutting to rotate downward to a vertical state. The waste inside the workpiece after cutting is separated from the workpiece by its own weight. The rotating assembly drives the rotating ring to rotate or reciprocate. The rotating ring drives the workpiece after cutting to vibrate, thereby shaking off the waste on the workpiece after cutting, realizing the separation of the waste and the workpiece, improving the surface quality of the workpiece after cutting, and preventing waste and other impurities from adhering to the workpiece;

[0016] 2. The rotating assembly drives the rotating ring and the workpiece to rotate synchronously. The rotating ring supports the workpiece to avoid the problem that when the laser cutter performs circular cutting on the workpiece, the workpiece is suspended in the air. As the connection part between the workpiece and the workpiece body gradually decreases, the workpiece will move relative to the workpiece body due to rotation and its own weight, which will affect the cutting quality of the workpiece.

[0017] 3. When cutting the workpiece, an external gas source supplies gas to the second end connector. The gas in the second end connector is blown into the workpiece through the end air hole and the telescopic sleeve. The gas can be oxygen or nitrogen. The gas removes the heat from the cutting area through the air flow, reducing the deformation and surface hardening of the pipe caused by local high temperature. This is especially important for thin-walled or high thermal conductivity materials (such as copper and aluminum pipes). Oxygen combustion can improve the cutting efficiency of carbon steel (the oxidation reaction releases additional heat energy), while nitrogen achieves oxidation-free cutting by isolating oxygen. It is suitable for metal pipes with high precision requirements. The gas can be selected according to the characteristics of the workpiece material.

[0018] 4. When the rotating sleeve rotates downward to separate the workpiece and waste, the external air source inputs high-pressure air pressure to the second end joint, and the gas is blown into the workpiece through the end air hole and the telescopic sleeve. The high-pressure gas can blow out the waste residue inside the workpiece;

[0019] 5. The fixed tube extends out of the telescopic sleeve and into the workpiece, and the fixed tube can push out the waste slag stuck inside the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In the embodiment of the present invention, when cutting a pipe workpiece, the feeding mechanism 2 drives the workpiece to rotate and move back and forth, thereby causing the workpiece to move and rotate under the laser cutter 102. The feeding mechanism 2 cooperates with the laser cutter 102 to cut the workpiece into various shapes. When the hollowing cutting on the side wall of the workpiece is completed and the workpiece needs to be cut and blanked, the electric telescopic rod 106 is in a retracted state, and the telescopic sleeve 105 is retracted in the rotating sleeve 103. The motor 104 drives the rotating sleeve 103 to rotate to a horizontal state, and the rotating sleeve 103 drives the telescopic sleeve 105 and the rotating ring 107 to rotate to a horizontal state. At this time, the rotating sleeve 103, the telescopic sleeve 105 and the rotating ring 107 are in a coaxial state with the workpiece, and the electric telescopic rod 106 begins to extend.

A waste box is provided under the cut workpiece to collect the waste.

[0041] Motor 104 continues to drive the rotating sleeve 103 to rotate, and the rotating sleeve 103 drives the cut workpiece away from the waste through the telescopic sleeve 105 and the rotating ring 107. Then the fixing component 5 releases the cut workpiece, and the cut workpiece is returned. The cutting process of one workpiece is completed.

With the joint cooperation of multiple clamping blocks 503, the inner wall of the workpiece is clamped, and the workpiece is fixed on the rotating ring 107.

[0049] In the embodiment of the present invention, when cutting a workpiece, the fixed tube 701 is retracted into the telescopic sleeve 105, and an external gas source supplies gas to the second end joint 704. The gas in the second end joint 704 is blown into the interior of the workpiece through the end air hole 703 and the telescopic sleeve 105. The gas can be oxygen or nitrogen. The gas removes heat from the cutting area through the air flow, reducing deformation and surface hardening of the pipe due to local high temperature. This is especially important for thin-walled or high-thermal-conductivity materials (such as copper and aluminum pipes). Oxygen combustion can improve the cutting efficiency of carbon steel (the oxidation reaction releases additional heat energy), while nitrogen achieves oxidation-free cutting by isolating oxygen, which is suitable for metal pipes with high-precision requirements.

[0050] When the rotating sleeve 103 rotates downward to separate the workpiece and the waste, the external air source inputs high-pressure air pressure to the end joint 704, and the air is blown into the workpiece through the end air hole 703 and the telescopic sleeve 105.

The side wall air holes 702 are set at an angle, and the gas is blown obliquely toward the inner wall of the workpiece. As the electric telescopic rod 106 contracts, the fixed tube 701 moves from one end of the workpiece to the other end of the workpiece, so that the side wall air holes 702 can fully pneumatically clean the inner wall of the workpiece. Combined with the rotation of the rotating ring 107, the rotating ring 107 drives the workpiece to rotate, further improving the cleaning effect of the side wall air holes 702 on the inner wall of the workpiece.

[0052] The above embodiment of the present invention provides a laser cutting device with a waste collection function. When cutting a workpiece, the feeding mechanism 2 drives the workpiece to rotate and move back and forth, thereby causing the workpiece to move and rotate under the laser cutter 102. The feeding mechanism 2 cooperates with the laser cutter 102 to cut the workpiece into various shapes. When the hollowing cutting on the side wall of the workpiece is completed and the workpiece needs to be cut and unloaded, the electric telescopic rod 106 is in a retracted state, and the telescopic sleeve 105 is retracted in the rotating sleeve 103. The motor 104 drives the rotating sleeve 103 to rotate to a horizontal state. The rotating sleeve 103 drives the telescopic sleeve 105 and the rotating ring 107 to rotate to a horizontal state. At this time, the rotating sleeve 103, the telescopic sleeve 105 and the rotating ring 107 are in a coaxial state with the workpiece. The electric telescopic rod 106 begins to extend, and the electric telescopic rod 106 drives the telescopic sleeve 105 to extend out of the rotating sleeve 103. The rotating sleeve 103 drives the rotating ring 107 to extend into the workpiece, and the fixing component 5 fixes the rotating ring 107 to the workpiece.

[0053] The feeding mechanism 2 drives the workpiece to rotate. When the laser cutter 102 performs circular cutting on the workpiece, the rotating assembly 6 drives the rotating ring 107 to rotate synchronously with the workpiece. The rotating ring 107 supports the workpiece, thereby preventing the problem that when the laser cutter 102 performs circular cutting on the workpiece, the workpiece to be cut is suspended. As the connection portion between the workpiece to be cut and the workpiece body gradually decreases, the workpiece to be cut and the workpiece body will move relative to each other due to the rotation and deadweight of the workpiece, which will affect the cutting quality of the workpiece.

[0054] After the workpiece is cut and unloaded, the electric telescopic rod 106 contracts, and the telescopic sleeve 105 drives the rotating ring 107 and the cut workpiece away from the workpiece body, so that when the cut workpiece rotates downward, it will not collide with the workpiece body. The motor 104 drives the rotating sleeve 103 to rotate downward, and the rotating sleeve 103 drives the telescopic sleeve 105, the rotating ring 107 and the cut workpiece to rotate downward to a vertical state. The waste inside the cut workpiece is separated from the cut workpiece by its own weight. The rotating component 6 drives the rotating ring 107 to rotate or reciprocate, and the rotating ring 107 drives the cut workpiece to vibrate, thereby shaking off the waste on the cut workpiece, thereby realizing the separation of the waste and the workpiece. The external air source inputs high-pressure air pressure to the end joint 2 704, and the gas is blown toward Inside the workpiece, the high-pressure gas can blow out the waste residue inside the workpiece, and when the electric telescopic rod 106 contracts and the telescopic sleeve 105 retracts into the rotating sleeve 103, the fixed tube 701 extends out of the telescopic sleeve 105, and the fixed tube 701 extends into the interior of the workpiece, the fixed tube 701 can push out the waste residue stuck inside the workpiece, and the gas in the fixed tube 701 is ejected through the side wall air holes 702. The side wall air holes 702 are tilted, and the gas is blown obliquely toward the inner wall of the workpiece. As the electric telescopic rod 106 contracts, the fixed tube 701 moves from one end of the workpiece to the other end of the workpiece, so that the side wall air holes 702 can fully pneumatically clean the inner wall of the workpiece, and then cooperate with the rotation of the rotating ring 107, the rotating ring 107 drives the workpiece to rotate, further improving the cleaning effect of the side wall air holes 702 on the inner wall of the workpiece;

[0055] Motor 104 continues to drive the rotating sleeve 103 to rotate, and the rotating sleeve 103 drives the cut workpiece away from the waste through the telescopic sleeve 105 and the rotating ring 107. Then the fixing component 5 releases the cut workpiece, and the cut workpiece is returned. The cutting process of one workpiece is completed. In the present invention, after the workpiece cutting is completed, there is no need to manually separate the workpiece and the waste, thereby improving the workpiece cutting efficiency.
