Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a cutting platform for a plasma cutting machine. Background Technology

[0002] Plasma cutting technology uses a high-speed plasma arc to melt conductive metal at high temperatures and then uses a jet of air to deliver the molten metal out of the cut. Due to its advantages such as fast cutting speed, narrow cut, and small heat-affected zone, it is widely used in shipbuilding, machining, steel structure fabrication, and workpiece waste recycling.

[0003] However, in actual production, especially during batch cutting, the number of cut panels is large and their shapes are different. If they cannot be separated in time, the residual heat of the panels can cause them to re-adhere at the cut, resulting in incomplete separation. Existing cutting platforms lack corresponding auxiliary separation structures, and separation is usually achieved by relying on the natural separation of the panels or by manual hammering, which is labor-intensive and requires careful control of the force used during hammering, making it quite inconvenient.

[0004] Therefore, there is an urgent need to design a cutting platform for plasma cutting machines that can promptly separate metal plates after cutting, reduce manual intervention, and thus improve production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a cutting platform for a plasma cutting machine. This cutting platform can automatically separate the metal plates after cutting, effectively prevent the problem of kerf adhesion caused by residual heat, reduce manual intervention, and improve production efficiency.

[0006] The technical solution adopted by this utility model to solve the above problems is: a cutting platform for a plasma cutting machine, including a base and a separation component. The base is provided with a perforated plate, and the perforated plate is provided with a number of sets of mesh holes. The separation component includes a bracket, and the bracket is provided with a support rod corresponding to the number of mesh holes. The support rod slides vertically through the mesh holes. The bracket is connected to a first driving component that drives it to move in the vertical direction. A vibration head is provided at the upper end of the support rod.

[0007] Preferably, the vibrating head includes a vibrating shell, and a vibrating motor is installed inside the vibrating shell. The vibrating motor is fixed to the upper end of the support rod by a spring connection.

[0008] Preferably, the base includes six sets of legs and two sets of crossbeams, with three sets of legs arranged at equal intervals below each set of crossbeams, and the mesh plate is disposed between the two sets of crossbeams.

[0009] Preferably, the first driving component includes four sets of driving cylinders, and the bracket is provided with four sets of connecting seats, which are connected and fixed to the piston rods of the driving cylinders.

[0010] Preferably, the mesh is provided with triangular protrusions around its perimeter, and the upper end of the protrusions is provided with rounded corners.

[0011] Preferably, it also includes an XY axis moving module, which includes two sets of X-axis guide rails and one set of Y-axis guide rails. A set of first sliding seats is provided below each end of the Y-axis guide rail. The first sliding seats are slidably connected to the X-axis guide rails below them. A first rack is provided on one side of any set of X-axis guide rails. A first drive motor is provided on the first sliding seat slidably connected above the set of X-axis guide rails.

Detailed Implementation

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0023] Example:

[0024] See Figures 1-6 In this embodiment, a cutting platform for a plasma cutting machine is disclosed. Specifically, it is used to effectively separate the cut metal plate after plasma cutting, preventing kerf adhesion due to residual heat, improving production efficiency, and reducing manual labor intensity. The platform includes a base 11 and a separation component 12. A perforated plate 13 is provided on the base 11, with several sets of mesh holes 14. The separation component 12 includes a support 15, on which a support rod 16 corresponding to the number of mesh holes 14 is provided. The support rod 16 slides vertically through the mesh holes 14. The support 15 is connected to a first driving component 17 that drives its vertical movement. A vibration head 18 is provided at the upper end of the support rod 16.

[0025] Specifically, after the cutting operation is completed, the cut metal plates often show signs of sticking together at the cut seam due to their residual heat. At this time, the first drive component 17 is activated, and the drive bracket 15 drives the support rod 16 to move upward along the mesh 14. After the support rod 16 successfully passes through the mesh 14, it continues to rise until the vibrating head 18 at the upper end of the support rod 16 is in close contact with the bottom surface of the metal plate. With the continuous action of the first drive component 17, the support rod 16 gradually lifts the metal plate upward, using the upward lifting force to overcome the sticking force at the cut seam. At the same time, the vibrating head 18 starts working, and the high-frequency vibration it generates can effectively loosen the metal parts that are stuck together at the cut seam due to residual heat, further assisting in the separation of the metal plates. This utility model achieves timely separation of the cut metal plates through the above process, reduces the need for manual intervention, effectively improves production efficiency, and solves the problem mentioned in the background art of the easy sticking of cut plates after cooling, which is inconvenient to manually knock. In actual use, the operator only needs to activate the first drive component 17 after the cutting operation is completed, and the entire separation process can be completed automatically.

[0026] Furthermore, to further reduce overall energy consumption, this embodiment incorporates a zoned management function for the vibrating heads 18 within the control system: based on the plasma cutting program and the placement of the plate, several groups of vibrating heads 18 corresponding to the area above the cutting kerf are designated as "active zones." After cutting, only the vibrating heads 18 within these active zones are powered on, while the remaining vibrating heads 18 remain in standby mode and do not require activation. This concentrates vibration energy on the most easily adhered areas while avoiding the significant amount of ineffective power consumption generated by vibration across the entire platform.

[0027] For details, see Figure 3 The vibrating head 18 includes a vibrating shell 19, inside which a vibrating motor 21 is installed. The vibrating motor 21 is connected and fixed to the upper end of the support rod 16 via a spring 22. When the vibrating motor 21 is powered on, the spring 22 ensures that the vibration impact can be effectively transmitted to the metal plate, and also absorbs excess vibration energy, reducing the impact on the bracket 15 and the base, which helps to extend the service life of the separation assembly 12.

[0028] In this embodiment, the base 11 includes six sets of support legs 23 and two sets of crossbeams 24. Three sets of support legs 23 are evenly spaced below each set of crossbeams 24, and the mesh plate is positioned between the two sets of crossbeams 24. The six sets of support legs 23 of the base 11 are fixed to the ground, providing stable support for the entire cutting platform. The two sets of crossbeams 24 are horizontally mounted on the six sets of support legs 23, and a perforated plate 13 is fixedly installed between them to form a working plane for the cutting operation.

[0029] See Figure 2The first driving component 17 includes four sets of driving cylinders 25, and the bracket 15 is provided with four sets of connecting seats 26. The connecting seats 26 are connected and fixed to the piston rods 27 of the driving cylinders 25. In this embodiment, the driving cylinders 25 are hydraulic cylinders of the same specification. When the hydraulic cylinders are working, the extension and retraction of the piston rods 27 drives the bracket 15 to move up and down, thereby realizing the vertical movement of the support rods 16 relative to the mesh 14. It should be noted that during the cutting operation, the bracket 15 needs to be lowered as a whole by the first driving component 17 so that the support rods 16 and the vibrating head 18 are away from the cutting heat source.

[0030] The mesh 14 is surrounded by triangular protrusions 28, which suspend the metal plate and allow molten slag to fall through the gap between the metal plate and the mesh 14. In this embodiment, a waste bin is also provided below the mesh 14 to collect molten slag or leftover material falling from above the mesh. The upper end of the protrusions 28 is rounded 29 to effectively reduce scratches on the bottom surface of the metal plate.

[0031] In this embodiment, the cutting platform further includes an XY-axis moving module 31, which includes two sets of X-axis guide rails 32 and one set of Y-axis guide rails 33. A set of first sliding seats 34 are provided below both ends of the Y-axis guide rails 33. (See also...) Figure 4 The first sliding seat 34 is slidably connected to the X-axis guide rail 32 below it, and a first rack 35 is provided on one side of any set of X-axis guide rails 32. A first drive motor 36 is provided on the first sliding seat 34 slidably connected above the set of X-axis guide rails 32. The output shaft of the first drive motor 36 is axially connected to a first transmission tooth 37 that meshes with the first rack 35. See also Figure 5 A second sliding seat 38 is slidably connected to the Y-axis guide rail 33. A second rack 39 is disposed above the Y-axis guide rail 33. A second drive motor 41 is disposed on the second sliding seat 38. The output shaft of the second drive motor 41 is shaft-connected to a second transmission gear 42 that meshes with the second rack 39. The first drive motor 36 drives the Y-axis guide rail 33 to move along the X-axis guide rail 32 through the meshing of the first transmission gear 37 and the first rack 35; the second drive motor 41 drives the second sliding seat 38 to move along the Y-axis guide rail 33 through the meshing of the second transmission gear 42 and the second rack 39. This dual-axis linkage structure can meet the cutting requirements of plasma cutting machines for various trajectories in the horizontal plane.

[0032] See Figure 6A linear module 43 is mounted on one side of the second sliding seat 38. This module includes a third drive motor 44, a screw 45, a slide rail 46, and a mounting base 47. The output shaft of the third drive motor 44 is fixedly connected to the screw 45 via a coupling 48. The mounting base 47 is threadedly fitted to the screw 45 and slidably connected to the slide rail 46. A cutting torch 49 is mounted and fixed on the mounting base 47. The linear module 43 is mounted on one side of the second sliding seat 38. Its third drive motor 44 drives the screw 45 to rotate via the coupling 48. The mounting base 47 is threadedly fitted to the screw 45 and slides along the slide rail 46, thereby enabling the cutting torch 49 to move vertically. During the cutting process, the distance between the nozzle at the bottom of the cutting torch 49 and the metal plate is adjusted by the linear module 43, allowing the plasma arc to cut the metal plate quickly and stably under optimal focusing conditions, effectively reducing molten slag splash and achieving better cutting results.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
