[0002] Laser cutting equipment is a mechanical device that uses laser beams for cutting. The laser cutting machine focuses the laser beam emitted by the laser into a high-power density beam, irradiates the surface of the workpiece, makes the material reach the melting point or boiling point, and then blows away the melted or vaporized material through high-speed gas coaxial with the beam, thereby achieving cutting.

[0003] The invention patent with the publication number CN117773356A discloses a profile laser cutting machine, a chassis for mounting cutting actuators; a five-axis cutting manipulator, which is arranged on the chassis and can move and cut profiles by itself; and a workpiece fixture, which is arranged on the side of the five-axis cutting manipulator and can convey and clamp profiles. The problem of difficulty in feeding I-beams, channel steels, angle steels and other profiles, and difficulty in moving profiles after cutting is solved.

A cutting hole 6 is penetrated through the top surface of the blanking platform 3, and the cutting blade 5 is plugged into the cutting hole 6. A lifting member is installed on the fixed frame 2, and the lifting member is used to drive the first motor 4 to lift and lower. A pressing mechanism is installed on the blanking platform 3, and the pressing mechanism is used to press the section of the profile to be cut on the top surface of the blanking platform 3.

[0037] The laser cutting head in the laser cutting machine body 1 is used for drilling holes on the surface of the profile. When the laser cutting machine body 1 is used, the profile is input into the laser cutting machine body 1 from the feed end, and then the profile is laser cut from the processing discharge end, and the profile after laser cutting is placed on the blanking table 3. Due to the obstruction of the internal ribs of the profile, the quality of the laser cutting head cutting the profile into segments is poor. Therefore, when it is necessary to cut the profile placed on the blanking table 3 into segments, the profile is first pressed and fixed on the blanking table 3 by the pressing mechanism, and then the first motor 4 is started, and the driving shaft of the first motor 4 drives the cutting blade 5 to rotate, and then the first motor 4 is driven to rise by the lifting member, and the first motor 4 drives the cutting blade 5 to rise, and the profile placed on the blanking table 3 is cut through the cutting hole 6.

[0038] For details, see Figure 2 and Figure 3 The lifting member is a lifting cylinder 38, and a lifting frame 39 is fixedly connected to one side of the fixed frame 2. The lifting cylinder 38 is fixed to one side of the lifting frame 39, the telescopic end of the lifting cylinder 38 faces upward, and the telescopic end of the lifting cylinder 38 is fixedly connected to the first motor 4.

[0039] When the lifting cylinder 38 is started, the lifting cylinder 38 drives the first motor 4 to rise, and the first motor 4 further drives the cutting blade 5 to rise.

[0040] For details, see Figure 2 , Figure 4 and Figure 5 The pressing mechanism includes a pressing block 7. The top surface of the blanking platform 3 is fixedly connected with a bracket 8. The inner side of the bracket 8 is fixedly connected with a first cylinder 9. The telescopic end of the first cylinder 9 faces downward, and the pressing block 7 is fixedly connected to the telescopic end of the first cylinder 9.

[0041] In addition, in order to avoid the damage of the profile caused by the pressing block 7 when the pressing block 7 presses the surface of the profile, and at the same time to facilitate the suction of the smoke caused by the cutting of the profile. The outer wall sliding sleeve of the pressing block 7 is provided with a suction box 10, and the suction box 10 is provided with a plurality of suction holes 11 on the side facing the cutting blade 5. The same side of the pressing block 7 facing the cutting blade 5 is penetrated by a plurality of through holes 12, and the positions of the through holes 12 and the suction holes 11 correspond, and the number of the through holes 12 and the suction holes 11 is the same. The side of the suction box 10 facing away from the cutting blade 5 is fixedly connected with a suction pipe 13, and the end of the suction pipe 13 facing away from the suction box 10 is fixedly connected with a suction piece (not shown in the figure). In this embodiment, the suction piece is a dust pump.

[0042] The pressing block 7 is also equipped with an elastic member, which is used to cooperate and drive the suction box 10 to slide. The elastic member is a first spring 14, and a pressing edge 15 is fixedly connected to the circumference of the pressing block 7, and a buffer rod 16 is fixedly connected to the bottom surface of the pressing edge 15. The bottom end of the buffer rod 16 passes through the suction box 10, and the buffer rod 16 is slidably connected to the suction box 10. The first spring 14 is sleeved on the buffer rod 16, and one end of the first spring 14 is fixedly connected to the bottom surface of the pressing edge 15, and the other end of the first spring 14 is fixedly connected to the top surface of the suction box 10.

[0043] When the first cylinder 9 is started, the telescopic end of the first cylinder 9 drives the pressure block 7 to descend, and the pressure block 7 drives the suction box 10 to descend. When the suction box 10 abuts against the profile, under the guidance of the first spring 14, the suction box 10 squeezes the first spring 14 upward, thereby buffering the squeezing force to avoid deformation of the profile. When the pressure block 7 continues to descend, the pressure block 7 finally abuts against the top surface of the profile, and the suction hole 11 and the through hole 12 are opposite and connected to each other. When it is necessary to suck the smoke generated during cutting, start the suction piece. At this time, the smoke passes through the suction hole 11 and the through hole 12 in turn, and finally flows into the suction pipe 13 to achieve the suction of the smoke.

[0044] See also Figure 2 , Figure 4 and Figure 6 In order to prevent the profile from shifting in the front-back direction when cutting, the bracket 8 is equipped with a centering clamping assembly, and two groups of centering clamping assemblies are provided. Each group of centering clamping assemblies includes a first clamping rod group 17 and a second clamping rod group 18. A second cylinder 19 is fixedly connected to the inner side of the bracket 8, and the telescopic end of the second cylinder 19 faces downward. The telescopic end of the second cylinder 19 is fixedly connected to a cross frame 20. The first clamping rod group 17 and the second clamping rod group 18 are symmetrically slidably installed on one side of the cross frame 20, and the first clamping rod group 17 and the second clamping rod group 18 enclose a clamping space 21 for the profile.

[0045] In addition, the cross frame 20 is also equipped with a driving member, which is used to drive the first clamping rod group 17 and the second clamping rod group 18 to move in a direction close to or away from each other at the same time, and the driving member is a third cylinder 22. A guide rail 23 is fixedly connected to one side of the cross frame 20, and the top surfaces of the first clamping rod group 17 and the second clamping rod group 18 are respectively fixedly connected to a guide seat 24, and the guide seat 24 is slidably connected to the guide rail 23.

The telescopic ends of the third cylinder 22 are respectively hinged with a first connecting rod 25 and a second connecting rod 26, the other end of the first connecting rod 25 is hinged to the top surface of the first clamping rod group 17, and the other end of the second connecting rod 26 is hinged to the top surface of the second clamping rod group 18.

[0046] When the second cylinder 19 is started, the telescopic end of the second cylinder 19 drives the cross frame 20 to descend until the profile is inserted into the clamping space 21. Then the third cylinder 22 is started. Under the guiding sliding action of the guide seat 24 and the guide rail 23, the third cylinder 22 drives the first clamping rod group 17 and the second clamping rod group 18 to move toward each other through the first connecting rod 25 and the second connecting rod 26. At this time, the first clamping rod group 17 and the second clamping rod group 18 jointly clamp the profile in the center to prevent the profile from shifting in the front and rear directions during cutting.

[0047] It is worth mentioning that see Figure 2 and Figure 4 A fourth cylinder 27 is fixedly connected to one side of the bracket 8, and a push plate 28 is fixedly connected to the telescopic end of the fourth cylinder 27. A clearance hole 29 is penetrated through the bottom surface of the push plate 28, and the cutting blade 5 is plugged into the clearance hole 29.

[0048] A movable rear chuck is originally installed in the laser cutting machine body 1, and the rear chuck is used to clamp and drag the profile to move, so as to ensure that the push plate 28 does not collide with the profile when pushing the profile. When the cut profile needs to be collected, the fourth cylinder 27 is started, and the telescopic end of the fourth cylinder 27 drives the push plate 28 to move, so that the push plate 28 pushes the profile placed on the blanking table 3 out of the blanking table 3, and the collection of the profile is completed.

[0049] In addition, the stripping plate 28 is lengthened to open the clearance hole 29, which is also helpful in blocking cutting sparks and debris, thereby protecting the equipment.

[0050] See also Figure 2 and Figure 7, a crossbar frame 30 is fixedly connected to the side of the fixed frame 2 away from the processing discharge end, and the crossbar frame 30 extends outside the blanking platform 3. An auxiliary support platform 31 is slidably installed on the top surface of the crossbar frame 30, and the number of auxiliary support platforms 31 is set to two. A vertical rod 32 is fixedly connected to the bottom surface of the auxiliary support platform 31, and a slide groove 33 is provided on the top surface of the crossbar frame 30, and the slide groove 33 is opened along the length direction of the crossbar frame 30. The bottom end of the vertical rod 32 is slidably connected to the slide groove 33, and the side wall of the vertical rod 32 is fixedly connected to a connecting frame 34, and the connecting frame 34 is set in an L shape. An insertion rod 35 is installed on one side of the connecting frame 34, and the insertion rod 35 passes through the connecting frame 34 toward one end of the crossbar frame 30, and the insertion rod 35 is slidably connected to the connecting frame 34. A slot 36 is provided on the outer side of the crossbar frame 30, and the number of the slots 36 is set to be multiple, and the multiple slots 36 are evenly distributed along the length direction of the crossbar frame 30. The end of the insertion rod 35 facing the crossbar frame 30 is respectively plugged into the slot 36. The side wall of the insertion rod 35 is sleeved with a second spring 37, one end of the second spring 37 is fixedly connected to the side wall of the insertion rod 35, and the other end of the second spring 37 is fixedly connected to the inner wall of the connecting frame 34.

[0051] When the length of the cut profile section is greater than the length of the blanking platform 3, it is necessary to adjust the position of the auxiliary support platform 31 and use the auxiliary support platform 31 to provide auxiliary support for the profile. To this end, the insertion rod 35 is driven to move in the direction away from the crossbar frame 30. At this time, the insertion rod 35 squeezes the second spring 37, and the insertion rod 35 is separated from the slot 36. After the insertion rod 35 is separated from the slot 36, the position of the auxiliary support platform 31 is moved and adjusted. After the position adjustment of the auxiliary support platform 31 is completed, the insertion rod 35 is released, the second spring 37 releases its elastic force, and drives the insertion rod 35 to move in the direction close to the crossbar frame 30. At this time, the insertion rod 35 is inserted into the slot 36, and the auxiliary support platform 31 is fixed at the current position.

[0052] The working principle of a flat-cut profile laser cutting equipment:

[0053] The laser cutting head in the laser cutting machine body 1 is used to drill holes on the surface of the profile. When the laser cutting machine body 1 is used, the profile is input into the laser cutting machine body 1 from the feed end, and then the profile is laser cut from the processing discharge end, and the profile after laser cutting is placed on the blanking table 3.

[0054] Due to the obstruction of the internal ribs of the profile, the quality of the laser cutting head cutting the profile into sections is poor. Therefore, when the profile placed on the blanking table 3 needs to be cut into sections, the first cylinder 9 is started, and the telescopic end of the first cylinder 9 drives the pressure block 7 to descend, and the pressure block 7 drives the suction box 10 to descend. When the suction box 10 abuts against the profile, under the guidance of the first spring 14, the suction box 10 squeezes the first spring 14 upward, thereby buffering the squeezing force to avoid deformation of the profile. When the pressure block 7 continues to descend, the pressure block 7 finally abuts against the top surface of the profile, and the suction hole 11 and the through hole 12 are opposite and connected to each other. When it is necessary to suck the smoke generated during cutting, the suction piece is started. At this time, the smoke passes through the suction hole 11 and the through hole 12 in turn, and finally flows into the suction pipe 13 to achieve the suction of the smoke.

[0055] Then the second cylinder 19 is started, and the telescopic end of the second cylinder 19 drives the cross frame 20 to descend until the profile is inserted into the clamping space 21. Then the third cylinder 22 is started, and under the guiding sliding action of the guide seat 24 and the guide rail 23, the third cylinder 22 drives the first clamping rod group 17 and the second clamping rod group 18 to move towards each other through the first connecting rod 25 and the second connecting rod 26. At this time, the first clamping rod group 17 and the second clamping rod group 18 jointly clamp the profile in the center to prevent the profile from shifting in the front and rear directions during cutting.

[0056] When it is necessary to cut the profile placed on the blanking table 3, the profile is first pressed and fixed on the blanking table 3 by the pressing mechanism, and then the first motor 4 is started, and the driving shaft of the first motor 4 drives the cutting blade 5 to rotate, and then the first motor 4 is driven to rise by the lifting member, and the first motor 4 drives the cutting blade 5 to rise, and the profile placed on the blanking table 3 is cut through the cutting hole 6.

[0057] After the profile is cut and the pressure on the profile is released, the fourth cylinder 27 is started, and the telescopic end of the fourth cylinder 27 drives the push plate 28 to move, and the push plate 28 pushes the profile placed on the blanking table 3 down, completing the collection of the profile.

[0058] In summary, the laser cutting machine body 1 meets the requirements of cutting various types of profiles, which not only improves the application scope of the laser cutting machine body 1, but also improves the efficiency of cutting processing.

[0059] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
