Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to an air-cooled bed-type dust-removing laser cutting machine. Background Technology

[0002] A laser cutting machine uses a laser beam emitted from a laser source, which is focused into a high-power-density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the purpose of cutting.

[0003] Current laser cutting machine references, such as CN202123019849.8 (a laser cutting machine with a dust extraction device) and CN202223017237.X (cooling device and laser cutting machine), mostly fix the cutting table to the machine bed, thus presenting the following problems:

[0004] 1) As the power of laser generators increases and the plates being cut become thicker, the heat generated during the cutting process accumulates inside the equipment, which can cause deformation of the bed and cutting table.

[0005] 2) The cutting table of the existing desktop laser cutting machine is fixed to the bed. The weight of the cutting table itself and the weight of the sheet metal are both applied to the bed. Over time, this will cause the bed to deform inward, affecting the cutting accuracy.

[0006] 3) Laser generators are becoming increasingly powerful, which can meet the cutting requirements of more customers for large-format panels. However, the larger the cutting area, the worse the dust removal and ventilation effect on both sides, which can lead to damage to the machine bed, work frame, and customer site.

[0007] 4) The larger the cutting area, the worse the dust removal effect. The metal dust generated during the cutting process will cause harm to the factory and operators, which does not meet the requirements of green and environmentally friendly production. Moreover, if the cutting is of combustible metals (aluminum, copper, etc.), the excessive metal dust density will cause a dust explosion, which is quite dangerous.

[0008] To address these issues, we offer an air-cooled, bed-mounted, dust-removing laser cutting machine. Utility Model Content

[0009] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an air-cooled, dust-removing laser cutting machine to solve the problems of deformation of the cutting table and laser cutting on the machine bed and excessive dust generated by laser cutting.

[0010] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an air-cooled bed-type dust removal laser cutting machine, including a cutting table and a cutting machine bed, wherein the cutting table and the cutting machine bed are separately arranged;

[0011] A crossbeam is mounted on the cutting machine body, and a laser cutting head is mounted on the crossbeam; the crossbeam moves on the cutting machine body; a water tank is placed at the bottom of the cutting table;

[0012] The cutting machine bed includes a dust removal air duct and an air cooling duct, which are used for dust removal and cooling of the cutting machine bed, respectively.

[0013] In a further technical solution, the top height of the cutting table is lower than the height of the crossbeam frame;

[0014] The cutting table includes a work frame, which is horizontal to the top surface of the cutting machine body; multiple sets of toothed plates are installed on the work frame and arranged in parallel, the toothed plates being used to support the workpiece.

[0015] In a further technical solution, the working frame includes a snap-fit ​​plate, and a snap-fit ​​groove is formed in the snap-fit ​​plate. The groove diameter is adapted to the thickness of the toothed plate; the top of the toothed plate has a toothed shape.

[0016] The bottom of the work frame is equipped with a ground support column, and adjustable feet are installed at the bottom of the cutting machine body.

[0017] In a further technical solution, the dust removal duct includes an upper longitudinal duct and an upper transverse duct, which are fixedly connected and arranged in a rectangular shape; the cutting table is installed within the rectangle formed by the upper longitudinal duct and the upper transverse duct.

[0018] A dust removal port is provided on the side of the upper longitudinal air duct opposite to the water tank, and an air outlet is installed at the end.

[0019] In a further technical solution, the air-cooling channel includes a lower longitudinal air duct and a lower transverse air duct, and two sets of the lower longitudinal air duct and the lower transverse air duct are provided and connected to each other; an air inlet is installed on one set of lower transverse air ducts, and a cooling port is opened on the other set of lower transverse air ducts.

[0020] The lower longitudinal duct is fixedly installed at the bottom of the upper longitudinal duct.

[0021] In a further technical solution, the ground support pillar is installed inside the water tank.

[0022] In a further technical solution, both the air inlet and the air outlet are located on the same side of the cutting machine body.

[0023] In a further technical solution, two sets of parallel longitudinal ducts are set up, with a reinforcing rib installed between them;

[0024] Two sets of parallel, longitudinally spaced ducts are installed in the lower part of the room, with reinforcing ribs installed between them.

[0025] In a further technical solution, an external air duct is installed outside the air outlet and connected to a dust removal device; the air inlet is connected to an external air duct and connected to a blower.

[0026] Compared with existing technologies, it has the following advantages:

[0027] This invention separates the cutting machine bed and the cutting table, so that the weight of the cutting table and the workpiece to be cut does not act on the bed, reducing deformation of the cutting machine bed caused by the weight of the workpiece and the cutting table itself. Secondly, continuous feeding onto the cutting table prevents vibrations from affecting the cutting accuracy of the laser cutting head. The separation also reduces heat conduction during cutting, minimizing deformation of the cutting machine bed due to prolonged overheating.

[0028] The upper tube of the cutting machine bed in this invention serves as a dust removal duct, while the lower tube serves as a cooling channel, both contributing to dust removal and cooling during the laser cutting process. A water tank is installed at the bottom of the work frame, which cools the machine and absorbs the generated metal dust during cutting. This water protection also reduces the likelihood of localized deformation of the customer's factory floor due to overheating. Attached Figure Description

[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] Example 1

[0052] Please see Figure 1 and2 As shown, this utility model provides a technical solution. It covers an air-cooled, bed-type dust-removing laser cutting machine, including a cutting table 10 and a cutting machine bed 20, which are separately arranged; as shown... Figure 1 As shown, a crossbeam frame 30 is installed on the cutting machine bed 20, and a laser cutting head 40 is installed on the crossbeam frame 30; the crossbeam frame 30 moves on the cutting machine bed 20; a water tank 50 is placed at the bottom of the cutting table 10; and water is filled in the water tank during operation.

[0053] like Figure 2 As shown, the cutting machine bed 20 includes a dust removal air duct 60 and an air-cooling duct 70, which are used for dust removal and cooling of the cutting machine bed 20, respectively. Adjustable feet 21 are installed at the bottom of the cutting machine bed 20. The ground support column 15 is installed in the water tank 50.

[0054] The laser cutting machine also includes related components or systems such as an air pump, control console, laser generator, transmission components, and mechanical transmission system. This application does not describe the aforementioned structures; however, the structures described refer to existing laser cutter structures, and are not elaborated upon here. For example, the laser generator can convert CO2 into a laser beam by converting electrical energy. The air pump is used in the air blowing system to assist the laser cutting process by blowing away molten slag and protecting the lens, while also assisting in the cutting process. The control console is used to control the movement of the crossbeam and the laser cutting head, including the corresponding travel path and cutting path.

[0055] like Figure 2 As shown, the top height of the cutting table 10 is lower than the height of the crossbeam frame 30.

[0056] This invention separates the cutting machine bed and the cutting table, so that the weight of the cutting table and the workpiece to be cut does not act on the bed, reducing deformation of the cutting machine bed caused by the weight of the workpiece and the cutting table itself. Secondly, continuous feeding onto the cutting table prevents vibrations from affecting the cutting accuracy of the laser cutting head. The separation also reduces heat conduction during cutting, minimizing deformation of the cutting machine bed due to prolonged overheating.

[0057] Example 2

[0058] like Figure 3-6 As shown, another embodiment of the present invention is provided. Based on embodiment 1, the cutting table 10 includes a working frame 11, which is horizontal to the top surface of the cutting machine bed 20. Multiple sets of toothed plates 12 are installed on the working frame 11 and arranged in parallel. The toothed plates 12 are used to support the workpiece.

[0059] Combination Figure 5 and 6As shown, the working frame 11 includes a snap-fit ​​plate 13, and a snap-fit ​​groove 14 is provided in the snap-fit ​​plate 13. The groove diameter of the snap-fit ​​groove 14 is adapted to the thickness of the toothed plate 12; the top of the toothed plate 12 is provided with a tooth shape.

[0060] The bottom of the working frame 11 is equipped with a ground support column 15.

[0061] This invention uses a snap-fit ​​plate to simultaneously snap-fit ​​multiple sets of toothed plates, ensuring that the multiple sets of toothed plates are installed in the same direction and in parallel, which is beneficial for bearing the workpiece.

[0062] Example 3

[0063] like Figure 7-13 As shown, this is another embodiment of the present invention, based on embodiment 2, as follows: Figure 7 and 8 As shown, the dust removal duct 60 includes an upper longitudinal duct 61 and an upper transverse duct 62, which are fixedly connected and arranged in a rectangular shape; the cutting table 10 is installed within the rectangle formed by the upper longitudinal duct 61 and the upper transverse duct 62.

[0064] Combination Figure 7 , 8 As shown in Figures 10 and 13, a dust removal port 63 is provided on the side of the upper longitudinal air duct 61 opposite to the water tank 50, and an air outlet 64 is installed at the end. In this embodiment, the dust removal port is a directional port facing the cutting table, used to absorb the smoke generated by laser cutting, combined with... Figure 10 The arrows indicate the direction of the adsorption airflow. The adsorption airflow enters the upper longitudinal duct from the dust collection ports on both sides, and then flows to the dust collection device through the outlet at the end. Figure 13 As shown. In particular, during powerful dust removal, it can also absorb the heat generated in the cutting table, achieving the combined advantages of cooling and dust removal.

[0065] Combination Figure 7 , 12 As shown in Figure 13, the air-cooled channel 70 includes a lower longitudinal air duct 71 and a lower transverse air duct 72, both of which are provided in two sets and connected to each other; an air inlet 73 is installed on one set of lower transverse air ducts 72, and a cooling outlet 74 is opened on the other set of lower transverse air ducts 72; the lower longitudinal air duct 71 is fixedly installed at the bottom of the upper longitudinal air duct 61. The air-cooled channel is as follows... Figure 12As shown, strong air enters through the bottom air inlet and flows through the bottom horizontal air duct to the lower vertical air ducts on both sides. The airflow then flows to the upper lower horizontal air duct and exits through the cooling vent, carrying away heat from the pipes. This heat is absorbed by the water tank, resulting in a cooling effect. The airflow also blows dust from the cutting table into the water tank at the bottom, where the water absorbs some of the dust. Therefore, it achieves the combined advantages of cooling and dust removal. Of course, the material being cut must be clearly identified before cutting to reduce the possibility of a reaction between the water and the cutting process, producing smoke.

[0066] like Figure 9 As shown, the air inlet 73 and the air outlet 64 are both located on the same side of the cutting machine bed 20.

[0067] like Figure 8 As shown, the upper longitudinal air duct 61 is provided in two sets and parallel to each other, and a reinforcing rib 65 is installed between them;

[0068] like Figure 7 As shown, the lower longitudinal air duct 71 is provided in two sets and parallel to each other, and a reinforcing rib 75 is installed between them.

[0069] like Figure 13 As shown, an external air duct is installed outside the air outlet 64 and connected to a dust removal device 80. Dust is treated in an environmentally friendly manner through the external air duct and the dust removal device; the dust removal device is usually located outside the factory building. The air inlet 73 is connected to an external air duct and a blower 90.

[0070] The upper tube of the cutting machine bed in this invention serves as a dust removal duct, while the lower tube serves as a cooling channel, both contributing to dust removal and cooling during the laser cutting process. A water tank is installed at the bottom of the work frame, which cools the machine and absorbs the generated metal dust during cutting. This water protection also reduces the likelihood of localized deformation of the customer's factory floor due to overheating.

[0071] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
