Description

A laser cutting device for metal material processing Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a laser cutting equipment for metal material processing. Background Technology

[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a narrow kerf, completing the cutting process. When a laser cutting device is in operation, a structure is typically needed to hold the metal material in place, allowing for transport, displacement, and rotation to coordinate with the laser cutting head. Existing laser cutting devices are not suitable for adapting to different lengths, widths, and even diameters of metal materials, making it difficult to continue the laser cutting process. Furthermore, existing laser cutting devices, while capable of handling small metal materials, do not readily adapt to the deformation of the transport structure to transport larger metal materials, thus hindering the improvement of the laser cutting device's applicability.

[0003] To address the aforementioned problems, a laser cutting device for metal material processing is proposed. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To address the technical problem of existing laser cutting devices being inconvenient for adapting to the length, width, and even diameter of different metal materials during clamping and transportation, as shown in Figures 1-5, the following preferred technical solutions are provided:

[0028] A laser cutting device for metal material processing includes a frame 1 and a laser cutting head 2 disposed at the upper part of the frame 1. A support platform 3 is disposed at the lower part of the frame 1. A deformation device 4 is disposed on one side of the frame 1. A rotating component 7 is movably disposed inside the deformation device 4. A conveying device 6 is disposed inside the rotating component 7. A guide rail 5 is movably disposed at the lower end of the deformation device 4, and two sets of guide rails 5 are provided. The deformation device 4 includes a first moving stage 41 and a second moving stage 42. The first moving stage 41 and the second moving stage 42 are components made of the same structure. The conveying device 6 is used to clamp and transport the metal material. The conveying device 6 has the effect of transporting and rotating the metal material to cooperate with the laser cutting head 2 to perform laser cutting on the metal material. When cutting large metal materials, the first moving stage 41 and the second moving stage 42 move in opposite directions through the setting of the guide rail 5. The large metal material is clamped by the conveying device 6, which has the effect of transporting the large metal material. The rotating component 7 drives the conveying device 6 to rotate, that is, it has the effect of rotating the large metal material.

[0029] The upper end of the first moving platform 41 is provided with a component groove 411, and the inner side of the first moving platform 41 is provided with an arc-shaped groove 412, which is connected to the component groove 411. The rotating component 7 is movably disposed inside the arc-shaped groove 412. The deformation device 4 is provided with a fixed connecting block 413 inside, and the rotating component 7 is connected to the conveying device 6 through the fixed connecting block 413. The conveying device 6 includes a first half-ring 61 and a second half-ring 62. The first half-ring 61 is provided with an inner ring groove 611 inside. The first half-ring 61 and the second half-ring 62 are components made of the same structure. The first half-ring 61 is fixedly connected to a set of fixed connecting blocks 413, and the second half-ring 62 is fixedly connected to another set of fixed connecting blocks 413.

[0030] The conveying device 6 also includes a first rotating ring 63 and a second rotating ring 64 movably fitted inside two sets of inner ring grooves 611. Each of the first rotating ring 63 and the second rotating ring 64 has a driven half-ring 69 inside. A second electric drive component 68 and a first electric drive component 67 are movably arranged inside one set of driven half-rings 69. Two sets of the first electric drive components 67 and the second electric drive components 68 are provided. First meshing wheels 66 are meshed on the outer sides of both the first rotating ring 63 and the second rotating ring 64. A first fixed motor 65 is connected to the first meshing wheel 66 via a shaft. The first fixed motor 65 is fixed inside the conveying device 6. Two sets of the first fixed motor 65 and the first meshing wheel 66 are provided. The first electric drive component 67 includes an electric drive lifting block 671 movably fitted inside the corresponding set of driven half-rings 69, and a first component strip arranged on one side of the electric drive lifting block 671. The first transport roller 672 and the first transport roller 673, the second electric drive component 68 includes an electric drive displacement block 681 movably fitted into a corresponding set of driven half rings 69, a connecting strip 682 is provided on one side of the electric drive displacement block 681, a second component strip 683 is provided on the outer side of the connecting strip 682, and a second transport roller 684 is movably provided on one side of the second component strip 683. The two sets of second transport rollers 684 are on the same vertical plane, the two sets of first transport rollers 673 are on the same vertical plane, and the shortest distance between the second transport roller 684 and the second rotating ring 64 is greater than the shortest distance between the first transport roller 673 and the second rotating ring 64. The first electric drive component 67, driven half ring 69 and second electric drive component 68 of one set are provided on the first rotating ring 63, and the first electric drive component 67, driven half ring 69 and second electric drive component 68 of the other set are provided on the second rotating ring 64.

[0031] Specifically, the metal material is placed inside the gap between the two sets of driven semi-rings 69. The two sets of electrically driven displacement blocks 681 and electrically driven lifting blocks 671 are electrically driven, causing them to move towards the center of the conveying device 6. At this time, the two sets of second transport rollers 684 and first transport rollers 673 come into contact with the metal material and clamp it. The two sets of second transport rollers 684 and first transport rollers 673 are electrically driven to rotate, thereby driving the metal material to move and increase or decrease the distance between the metal material and the laser cutting head 2, allowing the laser cutting head 2 to cut the metal material. By driving the first fixed motor 65, the two sets of first meshing wheels 66 rotate, thereby causing the first rotating ring 63, the second rotating ring 64, and the clamped metal material to rotate. That is, the metal material can be displaced and rotated, thus facilitating multi-directional cutting by the laser cutting head 2. The gap between the two sets of second transport rollers 684 and first transport rollers 673 can be varied to clamp metal materials of different sizes and diameters.

[0032] To address the technical challenge of existing laser cutting devices being unable to deform the transport structure to transport large metal materials when handling small parts, as shown in Figures 6-7, the following preferred technical solutions are provided:

[0033] The rotating assembly 7 includes a connecting ring 71 disposed inside the arc-shaped groove 412, and two sets of connecting rings 71 are provided. The interior of the connecting ring 71 is fixedly connected to a corresponding set of fixed connecting blocks 413. The rotating assembly 7 also includes a second motor 72 fixedly disposed inside the deformation device 4 and a second meshing wheel 73 connected to one side of the second motor 72 via a shaft. The rotating assembly 7 also includes an outer ring 74, and two sets of outer rings 74 are provided. A first external gear 712 is provided on the outer side of the connecting ring 71, and the first external gear 712 matches the second meshing wheel 73. Both ends of the connecting ring 71 are provided with fitting grooves 711. A second external gear 742 is provided on the outer side of the outer ring 74, and the second external gear 742 matches the second meshing wheel 73. Both ends of the outer ring 74 are provided with fitting strips 741, and the fitting strips 741 match the fitting grooves 711. The outer ring 74 is assembled with the corresponding connecting ring 71 by the action of an external robotic arm.

[0034] Specifically, when large metal materials need to be cut, the guide rail 5 allows the first moving stage 41 and the second moving stage 42 to move in opposite directions, thus increasing the distance between them. Once the first and second moving stages 41 and 42 have reached their extreme positions, the robotic arm clamps a set of outer insert rings 74 and moves them into the component groove 411. The fitting groove 711 and fitting strip 741 allow the outer insert rings 74 to engage with the two sets of connecting rings 71. Driven by the two sets of second motors 72, the two sets of second meshing wheels 73 rotate, causing the two sets of connecting rings 71 and the set of outer insert rings 74 to rotate. This rotation is limited by the arc-shaped groove 412, allowing rotation only on the same vertical plane. When the set of outer insert rings 74 reaches its lowest position, the robotic arm clamps it again. Another set of outer rings 74 is held so that they engage with the two sets of connecting rings 71, that is, the two sets of outer rings 74 and the two sets of connecting rings 71 form a complete ring. The rotation of the two sets of second meshing wheels 73 drives the rotation of the fixed connecting block 413 and the conveying device 6. Due to the opposite movement of the first moving table 41 and the second moving table 42, the distance between the first rotating ring 63 and the second rotating ring 64 increases. At this time, large metal materials are placed inside the gap between the first rotating ring 63 and the second rotating ring 64. The first transport roller 673 and the second transport roller 684 clamp and transport the large metal materials in the same way. The rotation of the two sets of connecting rings 71 and the two sets of outer rings 74 causes the large metal materials to rotate. Through the deformation of the same structure, the laser cutting device can cut both small and large metal materials at the same time, which improves the applicability of the device.
