[0002] Laser cutting machine is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point, and at the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal.

[0003] Since the laser cutting process will produce a heat-affected zone, which will cause thermal deformation or thermal stress of the workpiece, this effect will be more obvious when cutting profiles with internal ribs, affecting the cutting accuracy and quality of the workpiece. Therefore, some laser cutting equipment is often equipped with a cutting disc to cut profiles with internal ribs. After the laser processing of the profile is completed, the profile is cut by the cutting disc to ensure the quality of the profile cutting.

[0038] See also Figure 1 and Figure 2 A laser cutting device for bevel-cutting profiles includes a laser cutting body 1, which includes a feed end and a processing and discharging end. The profile enters the laser cutting body 1 from the feed end, and the profile is laser processed at the processing and discharging end. The processing and discharging end is fixedly connected to a fixed frame 2, and a fixed cover on the top surface of the fixed frame 2 is provided with a processing table 3. A first motor 4 is installed in the processing table 3, and a cutting blade 5 is coaxially fixedly connected to the driving shaft of the first motor 4. The fixed frame 2 is also equipped with a driving assembly, and the driving assembly is used to drive the first motor 4 to rise and fall and rotate. A cutting hole 6 runs through the top surface of the processing table 3. In this embodiment, there are two cutting holes 6, and the two cutting holes 6 are at different rotation angles. The cutting blade 5 is respectively plugged into the two cutting holes 6. The processing table 3 is also equipped with an extrusion mechanism, which is used to fix the profile to be cut on the processing table 3.

[0039] Select different cutting angles according to actual processing requirements. After the profile with internal ribs is input into the processing discharge end of the laser cutting machine body 1 and the laser processing is completed, the profile needs to be cut by the cutting blade 5. First, the profile is squeezed and fixed on the processing table 3 by the extrusion mechanism, and then the first motor 4 is started. The driving shaft of the first motor 4 drives the cutting blade 5 to rotate, and then the driving assembly finally drives the cutting blade 5 to rotate until the cutting blade 5 is aligned with the cutting hole 6 of the required angle, and then the driving assembly finally drives the cutting blade 5 to rise. At this time, the cutting blade 5 cuts the profile through the cutting hole 6. The cutting of the profile from different angles is completed.

[0040] For details, see Figure 2-Figure 4 The driving assembly includes a first cylinder 7 and a reduction motor 8. The first cylinder 7 is installed in the processing table 3, and the first cylinder 7 is fixedly installed on the inner side of the fixed frame 2. The telescopic end of the first cylinder 7 is fixedly connected to the lifting frame 9, and the lifting frame 9 is arranged in a Z shape. The reduction motor 8 is fixedly installed on the top surface of the lifting frame 9, and the output shaft of the reduction motor 8 is fixedly connected to the rotating frame 10, which is also arranged in a Z shape, and the first motor 4 is fixedly installed on the top surface of the rotating frame 10.

[0041] When the first cylinder 7 is started, the telescopic end of the first cylinder 7 drives the lifting frame 9 to rise, the lifting frame 9 drives the reduction motor 8 to rise, the reduction motor 8 drives the rotating frame 10 to rise, the rotating frame 10 drives the first motor 4 to rise, and the first motor 4 further drives the cutting blade 5 to rise. At this time, the cutting blade 5 cuts the profile through one of the cutting holes 6.

[0042] When the reduction motor 8 is started, the reduction motor 8 drives the rotating frame 10 to rotate, the rotating frame 10 drives the first motor 4 to rotate, and the first motor 4 drives the cutting blade 5 to rotate. At this time, the cutting blade 5 is aligned with the cutting hole 6 of the required angle.

[0043] See also Figure 2-Figure 4 A bracket 11 is fixedly connected to one side of the fixed frame 2, and a stop swing hole 12 is penetrated through the top surface of the bracket 11, and the stop swing hole 12 is arranged in an arc shape. A swing rod 13 is swingably installed in the stop swing hole 12, and the swing rod 13 is arranged in an L-shaped shape. One end of the swing rod 13 is fixedly connected to a smoke hood 14, and the other end of the swing rod 13 extends below the bracket 11, and the other end of the swing rod 13 is a plug-in end. The side wall of the smoke hood 14 is fixedly connected to a suction pipe 15, and the end of the suction pipe 15 away from the smoke hood 14 is fixedly connected to a suction piece (not shown in the figure). Among them, the suction piece is a dust pump.

[0044] In addition, in order to facilitate the fume hood 14 to always face the cutting blade and keep it parallel to the cutting blade during the cutting operation, and to absorb the smoke generated during the cutting to the maximum extent, the rotating frame 10 is equipped with a transmission assembly, which is used to drive the swing rod 13 to swing. The transmission assembly includes a swing cylinder 16, which is arranged in an L shape, and is installed on the top surface of the rotating frame 10, and one end of the swing cylinder 16 is connected to the top surface of the rotating frame 10, and the plug-in end of the swing rod 13 is plugged with the other end of the swing cylinder 16.

[0045] When the rotating frame 10 rotates, the rotating frame 10 drives the swing cylinder 16 to rotate, the swing cylinder 16 drives the swing rod 13 to rotate, and the swing rod 13 drives the smoke hood 14 to swing, so that the smoke hood 14 always remains facing the cutting knife. When the rotating frame 10 descends, the rotating frame 10 drives the swing cylinder 16 to descend, the swing cylinder 16 and the swing rod 13 slide relative to each other, and the smoke hood 14 remains at the current height, so as to avoid interference and collision between the swing rod 13 or the smoke hood 14 and the profile when descending.

[0046] It is worth noting that when the cutting knife is aligned with one of the cutting holes 6, the swing rod 13 is placed at one end of the stop swing hole 12. When the cutting knife is aligned with the other cutting hole 6, the swing rod 13 is placed at the other end of the stop swing hole 12.

[0047] See also Figure 4 In order to avoid interference and collision between the swing tube 16 and the profile when the cutting knife is fully reset and swung, the rotating frame 10 is equipped with an auxiliary part, which is used to cooperate and drive the swing tube 16 to swing, and the auxiliary part is a first spring 17. An extrusion groove 18 is provided on the top surface of the rotating frame 10, and the extrusion groove 18 is arranged in an arc shape. An extrusion rod 19 is fixedly connected to one end of the swing tube 16, and the extrusion rod 19 is inserted into the extrusion groove 18, and the extrusion rod 19 is slidably connected to the extrusion groove 18. The first spring 17 is installed in the extrusion groove 18, and one end of the first spring 17 is fixedly connected to the extrusion rod 19, and the other end of the first spring 17 is fixedly connected to the groove wall of the extrusion groove 18.

[0048] When the swing rod 13 is placed at the other end of the stop swing hole 12 and the rotating frame 10 continues to reset and rotate, the swing cylinder 16 squeezes the first spring 17, and the rotating frame 10 rotates relatively with the swing cylinder 16. Under the elastic force of the first spring 17, the swing cylinder 16 is positioned at the current position to avoid interference and collision with the profile.

[0049] For details, see Figure 5 and Figure 6 The extrusion mechanism includes an extrusion block 20. A stand 21 is fixedly connected to the top surface of the processing table 3, and two second cylinders 22 are fixedly installed on the inner side of the stand 21. The number of the extrusion blocks 20 is the same as the number of the second cylinders 22, and the extrusion blocks 20 are fixedly installed at the telescopic ends of the second cylinders 22.

[0050] When the second cylinder 22 is started, the telescopic end of the second cylinder 22 drives the extrusion block 20 to descend, and the extrusion block 20 is thereby pressed on the top surface of the profile. At this time, the profile is fixed on the processing table 3 in the up and down directions.

[0051] It should be noted that in order to prevent the profile from changing its position in the front-to-back direction, the vertical frame 21 is also equipped with an adjustment component, which is used to center and correct the section to be cut of the profile. There are two groups of adjustment components, each of which includes a first clamping rod group 23 and a second clamping rod group 24. A third cylinder 25 is fixedly installed on the inner side of the vertical frame 21, and the telescopic end of the third cylinder 25 is fixedly connected to a cross frame 26, and one side of the cross frame 26 is fixedly connected to a fixed rail 27. The top surfaces of the first clamping rod group 23 and the second clamping rod group 24 are fixedly connected to a slide 28, and the slide 28 is slidably connected to the fixed rail 27. A fourth cylinder 29 is also fixedly installed on one side of the cross frame 26, and the telescopic ends of the fourth cylinder 29 are respectively hingedly installed with a first connecting rod 30 and a second connecting rod 31. One end of the first connecting rod 30 away from the fourth cylinder 29 is hinged to the slide seat 28 on the first clamping rod group 23 , and one end of the second connecting rod 31 away from the fourth cylinder 29 is hinged to the slide seat 28 on the second clamping rod group 24 .

[0052] When the third cylinder 25 is activated, the third cylinder 25 drives the cross frame 26 to descend, and the cross frame 26 simultaneously drives the first clamping rod group 23 and the second clamping rod group 24 to descend. When the profile is placed between the first clamping rod group 23 and the second clamping rod group 24, the fourth cylinder 29 is activated, and the telescopic end of the fourth cylinder 29 is upward, and the fourth cylinder 29 drives the first clamping rod group 23 and the second clamping rod group 24 to move toward each other through the first connecting rod 30 and the second connecting rod 31, so as to achieve the clamping of the profile in the middle in the front-back direction.

[0053] See also Figure 2 and Figure 7 In order to facilitate the support of the profile to be cut longer than the processing table 3, an extension frame 32 is fixedly connected to one side of the fixed frame 2. The extension frame 32 extends outside the processing table 3, and a support table 33 is fixedly installed on the extension frame 32, and the number of the support tables 33 is set to two.

[0054] The extension frame 32 includes a main frame 34, one end of which is fixedly connected to the fixed frame 2, and the other end of the main frame 34 extends outside the processing table 3. A first sub-frame 35 is slidably mounted on the bottom surface of the main frame 34, and a second sub-frame 36 is slidably mounted on the bottom surface of the first sub-frame 35. One of the brackets 33 is fixedly mounted on the top surface of the first sub-frame 35, and the other bracket 33 is fixedly mounted on the top surface of the second sub-frame 36.

[0055] In addition, in order to facilitate the fixing of the positions of the first sub-frame 35 and the second sub-frame 36, the main frame 34 is also installed with a fixing assembly, and the fixing assembly includes an insertion rod 37. A fixing seat 38 is fixedly installed on the top surface of the main frame 34, and the cross-section of the fixing seat 38 is L-shaped. The bottom end of the insertion rod 37 passes through the fixing seat 38, and the insertion rod 37 is slidably connected to the fixing seat 38. The top surfaces of the first sub-frame 35 and the second sub-frame 36 are penetrated by a plug hole 39, and the number of the plug holes 39 is provided in plurality. The multiple plug holes 39 of the first sub-frame 35 and the second sub-frame 36 are evenly distributed in a linear array. The insertion rods 37 are respectively plugged into the plug holes 39, and the side walls of the insertion rods 37 are sleeved with second springs 40, one end of the second spring 40 is fixedly connected to the side wall of the insertion rod 37, and the other end of the second spring 40 is fixedly connected to the inner top wall of the fixing seat 38.

[0056] By driving the first sub-frame 35 and the second sub-frame 36 to slide respectively, the support platform 33 can adapt to the length of the profile to be cut. When the insertion rod 37 is lifted up, the insertion rod 37 squeezes the second spring 40, and the insertion rod 37 is separated from the insertion hole 39. At this time, the length of the first sub-frame 35 and the second sub-frame 36 is stretched and adjusted. When the insertion rod 37 is released, the second spring 40 releases the elastic force and drives the insertion rod 37 to descend. At this time, the insertion rod 37 is inserted into the insertion holes 39 on the first sub-frame 35 and the second sub-frame 36, and the main frame 34, the first sub-frame 35 and the second sub-frame 36 are relatively fixed.

[0057] It is worth noting that see Figure 5 In order to facilitate the collection of the cut profiles, a fifth cylinder 41 is fixedly installed on one side of the stand 21, and a push plate 42 is fixedly connected to the telescopic end of the fifth cylinder 41. A clearance groove 43 is opened on the surface of the push plate 42, and the clearance groove 43 corresponds to the position of the cutting hole 6, and the cutting blade 5 is plugged into the clearance groove 43.

[0058] The laser cutting machine body 1 is originally equipped with a movable rear chuck, which is used to clamp and drag the profile to move, ensuring that the push plate 42 does not collide with the profile when pushing the material. In addition, the push plate 42 is lengthened to open the clearance groove 43, which is also conducive to blocking cutting sparks and debris, and protecting the equipment.

[0059] Working principle of a bevel profile laser cutting equipment:

[0060] Different cutting angles are selected according to actual processing requirements. After the profile with internal ribs is input to the processing discharge end of the laser cutting machine body 1 and the laser processing is completed, the profile needs to be cut by the cutting blade 5 .

[0061] First, the second cylinder 22 is started, and the telescopic end of the second cylinder 22 drives the extrusion block 20 to descend, so that the extrusion block 20 is squeezed on the top surface of the profile, and the profile is fixed on the processing table 3 in the up and down direction. Then the third cylinder 25 is started, and the third cylinder 25 drives the cross frame 26 to descend, and the cross frame 26 simultaneously drives the first clamping rod group 23 and the second clamping rod group 24 to descend. And when the profile is placed between the first clamping rod group 23 and the second clamping rod group 24, the fourth cylinder 29 is started, and the telescopic end of the fourth cylinder 29 is upward, and the fourth cylinder 29 drives the first clamping rod group 23 and the second clamping rod group 24 to move in a direction close to each other through the first connecting rod 30 and the second connecting rod 31, so as to achieve the clamping of the profile in the front and back directions.
