Description

Technical Field

[0001] The present invention belongs to the technical field of laser cutting, and particularly relates to a laser cutting device with a waste collection function. Background Art

[0002] A laser cutting device is a device that uses a high-energy laser beam to cut and process pipes. Its core functions include cutting, perforating, beveling, and cutting special-shaped profiles.

[0003] When processing a workpiece, a laser cutting machine can perform hollowing processing on the side wall of the workpiece. For example, it can cut notches in the shapes of circles and long strips on the side walls of pipes such as round pipes, square pipes, and polygonal pipes. During cutting, the pipe fittings are placed horizontally, and the laser cutting device works above the pipe fittings.

[0004] The waste after cutting is likely to fall inside the pipe fittings or adhere to the workpiece. The waste includes scraps and welding slag, etc. After the pipe fittings are cut, generally, it is necessary to manually separate the pipe fittings from the waste, clean the pipe fittings to improve the surface quality of the pipe fittings. Manually handling the waste increases the labor intensity of workers, adds the processing procedures of the workpiece, and reduces the efficiency of laser cutting. Therefore, a laser cutting device that can automatically separate the workpiece from the waste and collect the waste is needed. Summary of the Invention

[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 after cutting 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 to be cut is suspended in the air. As the connection part 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 rotation and deadweight, 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 joint, and the gas in the second end joint is blown to the inside of the workpiece through the end air hole and the telescopic sleeve. The gas can be oxygen or nitrogen, etc. The gas takes away the heat in the cutting area through the air flow, reducing the deformation and surface hardening of the pipe due to local high temperature, which is especially important for thin-walled or high thermal conductivity materials (such as copper pipes and aluminum pipes). Oxygen combustion can improve the cutting efficiency of carbon steel (oxidation reaction releases additional heat energy), while nitrogen can achieve non-oxidation cutting by isolating oxygen, which is suitable for metal pipes with high precision requirements. The gas can be selected according to the material characteristics of the workpiece;

[0018] 4. When the rotating sleeve rotates downward to separate the workpiece and the 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

[0036] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0037] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0038] As Figure 1 、 Figure 2 and Figure 7 shown, a laser cutting device with a waste collection function provided by an embodiment of the present invention includes a cutting table 101, a laser cutter 102 and a feeding mechanism 2 arranged at the upper end of the cutting table 101, and further includes: a rotating sleeve 103 rotatably connected to the upper end of the cutting table 101 through a bracket, a motor 104 installed on the cutting table 101, and a rotating end of the motor 104 is connected to the side wall of the rotating sleeve 103; a telescopic sleeve 105 is slidably connected to the rotating sleeve 103 along the length direction, an electric telescopic rod 106 is fixed on the side wall of the rotating sleeve 103, and a telescopic end of the electric telescopic rod 106 is connected to the telescopic sleeve 105; one end of the telescopic sleeve 105 is rotatably connected to a rotating ring 107, a fixing component 5 and a rotating component 6 are arranged on the rotating ring 107, the fixing component 5 is used to fixedly connect the rotating ring 107 with the workpiece, the rotating component 6 is used to drive the rotating ring 107 to rotate, and the feeding mechanism 2 is used to convey and rotate the workpiece.

[0039] In the embodiment of the present invention, when cutting a pipe workpiece, the feeding mechanism 2 drives the workpiece to rotate and move forward and backward, 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 hollow 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, 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. The electric telescopic rod 106 drives the telescopic sleeve 105 to extend out of the rotating sleeve 103, and the rotating sleeve 103 drives the rotating ring 107 to extend into the workpiece. The fixing component 5 fixes the rotating ring 107 to the workpiece, and the feeding mechanism 2 drives the workpiece to rotate. When the laser cutter 102 performs annular cutting on the workpiece, the rotating component 6 drives the rotating ring 107 to rotate synchronously with the workpiece. The rotating ring 107 supports the workpiece to avoid the problem that when the laser cutter 102 performs annular cutting on the workpiece, the workpiece to be cut is suspended in the air. As the connection part 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.

[0040] 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, and 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, and the waste inside the cut workpiece is separated from the cut workpiece by its own weight, and the rotating component 6 drives the rotating ring 107 to rotate or reciprocate, and the rotating ring 107 drives the cut workpiece to vibrate, and then the waste on the cut workpiece is shaken off, so as to separate the waste from the workpiece, improve the surface quality of the workpiece after cutting, and avoid waste and other impurities adhering to the workpiece. A waste box is set below the cut workpiece to collect the waste;

[0041] The 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, and then the fixing component 5 releases the cut workpiece, thereby allowing the cut workpiece to be withdrawn, and 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.

[0042] like Figure 1 , Figure 9 and Figure 10As shown, as a preferred embodiment of the present invention, the feeding mechanism 2 includes a moving block 201, and a rotating assembly 3 and a moving assembly 4 connected to the moving block 201. The moving assembly 4 is used to drive the moving block 201 to move. A rotating sleeve 202 is rotatably connected inside the moving block 201. Two bolts 203 are threadedly connected to the rotating sleeve 202. One end of the bolt 203 extending into the rotating sleeve 202 is rotatably connected to a fixed block 204. The rotating assembly 3 is used to drive the rotating sleeve 202 to rotate. A guiding bracket 205 is fixed at the upper end of the cutting table 101. The guiding bracket 205 plays a role in supporting and guiding the workpiece. A through hole for the movement of the workpiece is provided on the guiding bracket 205. The rotating assembly 3 includes an external gear ring 301 fixed on the side wall of the rotating sleeve 202, and a second motor 303 fixed on the moving block 201. The rotating end of the second motor 303 is connected to a first gear 302. The first gear 302 meshes with the external gear ring 301. The moving assembly 4 includes two guide rails 401 fixed at the upper end of the cutting table 101. The moving block 201 is slidably connected to the two guide rails 401. A third motor 403 is fixed on the cutting table 101. The rotating end of the third motor 403 is connected to a lead screw 402. The lead screw 402 passes through the moving block 201 and is threadedly connected to the moving block 201. The lead screw 402 is rotatably connected to the cutting table 101.

[0043] In the embodiment of the present invention, one end of the workpiece is passed through the guiding bracket 205, and the other end of the workpiece is placed inside the rotating sleeve 202. The two bolts 203 are rotated. The bolts 203 drive the fixed block 204 to move by means of screw transmission. The two fixed blocks 204 clamp the other end of the workpiece, so that the other end of the workpiece is fixed on the moving block 201. The third motor 403 drives the lead screw 402 to rotate.

[0044] As Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, as a preferred embodiment of the present invention, the fixing component 5 includes a plurality of piston cavities 501 provided on the rotating ring 107. The plurality of piston cavities 501 are radially arranged with the axis of the rotating ring 107 as the center. A piston block 502 is slidably connected in the plurality of piston cavities 501. A clamping block 503 is fixed to the end of the piston block 502 away from the telescopic sleeve 105. An air-operated module is provided on the telescopic sleeve 105, and the air-operated module is used to drive the piston block 502 to move; the air-operated module includes a compression spring 504 fixed to the end of the piston block 502 away from the telescopic sleeve 105. The compression spring 504 is arranged in the piston cavity 501. An air groove 506 is provided in the telescopic sleeve 105. An end joint one 508 is fixed to the side wall of the telescopic sleeve 105. The end joint one 508 is connected to one end of the air groove 506. An avoidance groove 509 for avoiding the movement of the end joint one 508 is provided on the rotating sleeve 103. The end joint one 508 is connected to an external air source. The external air source includes an air pump or an air compressor, etc. An annular sunk groove 505 is provided on the side wall of the telescopic sleeve 105. A plurality of connection holes 507 communicating with the other end of the air groove 506 are uniformly arranged in the annular sunk groove 505. One end of the piston cavity 501 close to the annular sunk groove 505 is communicated with the annular sunk groove 505.

[0045] In the embodiment of the present invention, when the rotating ring 107 is inside the workpiece, the external air source supplies air into the end joint one 508. The gas in the end joint one 508 enters the piston cavity 501 through the air groove 506, the connection hole 507 and the annular sunk groove 505. The gas in the piston cavity 501 overcomes the elastic force of the compression spring 504 and drives the piston block 502 to move. The piston block 502 drives the clamping block 503 to contact the inner wall of the workpiece. With the cooperation of the plurality of clamping blocks 503, the inner wall of the workpiece is clamped, and then the workpiece is fixed on the rotating ring 107.

[0046] As Figures 2 - 4 shown, as a preferred embodiment of the present invention, the rotating component 6 includes a motor four 601 fixed to the side wall of the telescopic sleeve 105. The rotating end of the motor four 601 is connected to a gear two 602. An internal gear ring 603 is fixed to the inner wall of the rotating ring 107. The internal gear ring 603 meshes with the gear two 602.

[0047] In the embodiment of the present invention, the motor four 601 drives the gear two 602 to rotate. The gear two 602 drives the internal gear ring 603 to rotate. The internal gear ring 603 drives the rotating ring 107 to rotate. The rotating ring 107 drives the workpiece to rotate through the plurality of clamping blocks 503.

[0048] As Figure 5 、 Figure 6 and Figure 8As shown, as a preferred embodiment of the present invention, a fixed tube 701 is fixed inside the rotating sleeve 103. The fixed tube 701 is arranged inside the telescopic sleeve 105. One end of the fixed tube 701 is communicated with an end joint two 704. The end joint two 704 extends out from the side wall of the rotating sleeve 103, and the end joint two 704 is connected to an external air source. The external air source includes an air pump or an air compressor, etc. The other end of the fixed tube 701 is provided with an end air hole 703. A plurality of side wall air holes 702 are uniformly arranged on the side wall of the fixed tube 701 near one end of the end air hole 703.

[0049] In the embodiment of the present invention, during workpiece cutting, the fixed tube 701 is retracted inside the telescopic sleeve 105. The external air source supplies air to the end joint two 704. The gas in the end joint two 704 blows towards the inside of the workpiece through the end air hole 703 and the telescopic sleeve 105. The gas can be oxygen or nitrogen, etc. The gas takes away the heat in the cutting area through the air flow, reducing the deformation and surface hardening of the pipe caused by local high temperature. This is particularly important for thin-walled or high-thermal-conductivity materials (such as copper pipes and aluminum pipes). Oxygen can promote the cutting efficiency of carbon steel (the oxidation reaction releases additional heat energy), while nitrogen realizes oxidation-free cutting by isolating oxygen and is suitable for metal pipes with high-precision requirements. The gas can be selected according to the material characteristics of the workpiece.

[0050] When the rotating sleeve 103 rotates downward to separate the workpiece from the waste, the external air source inputs high-pressure air pressure to the end joint two 704. The gas blows towards the inside of the workpiece through the end air hole 703 and the telescopic sleeve 105. The high-pressure gas can blow out the waste residue inside the workpiece.

[0051] Moreover, 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 inside of the workpiece. The fixed tube 701 can push out the waste residue stuck inside the workpiece (as Figure 8 shown). And the gas in the fixed tube 701 sprays out through the side wall air holes 702. The side wall air holes 702 are inclined. The gas blows obliquely towards 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 perform pneumatic cleaning on the inner wall of the workpiece. Then, 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 forward and backward, so that the workpiece moves and rotates under the laser cutter 102. The feeding mechanism 2 cooperates with the laser cutter 102 to cut the workpiece into various shapes. When the hollow cutting on the side wall of the workpiece is completed, when 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, 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, and the electric telescopic rod 106 drives the telescopic sleeve 105 to extend out of the rotating sleeve 103, and 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 to avoid the problem that when the laser cutter 102 performs circular cutting on the workpiece, the workpiece to be cut is suspended in the air. As the connection part between the workpiece to be cut and the workpiece body is gradually reduced, 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 blanked, 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. Thus, when the cut workpiece rotates downward, it will not collide with the workpiece body. The first 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 assembly 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 and realizing the separation of the waste from the workpiece. The external air source inputs high-pressure air pressure into the second end joint 704, and the gas blows into the workpiece interior through the end air holes 703 and the telescopic sleeve 105. The high-pressure gas can blow out the waste residue inside the workpiece. Moreover, when the electric telescopic rod 106 contracts and the telescopic sleeve 105 retracts into the rotating sleeve 103, the fixed pipe 701 extends out of the telescopic sleeve 105, and the fixed pipe 701 extends into the workpiece interior. The fixed pipe 701 can push out the waste residue stuck inside the workpiece, and the gas inside the fixed pipe 701 jets out through the side wall air holes 702. The side wall air holes 702 are inclined, and the gas blows obliquely against the inner wall of the workpiece. As the electric telescopic rod 106 contracts, the fixed pipe 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 perform pneumatic cleaning on the inner wall of the workpiece. Coupled 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] The first motor 104 continues to drive the rotating sleeve 103 to rotate. 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 assembly 5 releases the cut workpiece, thereby enabling the cut workpiece to be unloaded. The cutting process of one workpiece ends. In the present invention, after the workpiece cutting is completed, there is no need for manual separation of the workpiece and the waste, improving the workpiece cutting efficiency.

[0056] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
