Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically a water-cooled, split-type 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) In existing desktop laser cutting machines, the cutting table 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 can cause the bed to deform inward, affecting the cutting accuracy.

[0005] 2) The integrated long-stroke tabletop laser cutting machine is used by customers in two sections: one for loading and unloading, and the other for cutting. During the loading and unloading process, the vibration will be transmitted to the running parts through the cutting table, thus affecting the cutting quality.

[0006] 3) As laser power increases, the plates being cut become thicker, and the heat generated during cutting can cause thermal deformation of the machine bed, especially when the equipment has a bevel cutting function, the heat generated is even greater.

[0007] To address these issues, we offer a water-cooled, split-bed laser cutting machine. Utility Model Content

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a water-cooled, split-bed laser cutting machine to solve the technical problems of pressure and thermal effects on the cutting machine bed caused by the cutting table and workpiece pressing, and laser cutting.

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[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 cutting machine bed includes transverse columns and longitudinal columns, distributed in a rectangular area; a reinforcing column is provided between the two sets of longitudinal columns, and the reinforcing column is arranged parallel to the transverse columns;

[0018] The cutting table is installed within the rectangular area enclosed by the horizontal and vertical columns.

[0019] In a further technical solution, the cooling water channel includes an upper water channel and a lower water channel; the upper water channel and the lower water channel are located on the upper and lower sides of the longitudinal column, respectively.

[0020] In a further technical solution, the upper water channel includes two sets of upper longitudinal pipes and two sets of upper transverse pipes. The upper longitudinal pipes are installed parallel to each other on the upper side of the longitudinal column. The two sets of upper longitudinal pipes are parallel and connected to the two sets of upper transverse pipes. An inlet is installed at the end of one set of upper longitudinal pipes and an upper connecting pipe is also installed thereon.

[0021] Two sets of upper horizontal pipes are set in parallel, and the set of upper horizontal pipes furthest from the water inlet is connected to the two sets of upper longitudinal pipes respectively.

[0022] Another set of upper horizontal pipes has an outlet on the outer side of the end near the inlet, which is not connected to the upper vertical pipe with the inlet, and the other end is connected to the corresponding upper vertical pipe.

[0023] An upper pipe 2 is installed on the water outlet 1; the upper pipe 1 and the upper pipe 2 are located on the same side of the cutting machine bed.

[0024] In a further technical solution, the lower water channel includes two sets of lower longitudinal pipes and two sets of lower transverse pipes. The lower longitudinal pipes are installed parallel to each other on the lower side of the longitudinal column. The two sets of lower longitudinal pipes are parallel and connected to the two sets of lower transverse pipes. A water inlet two and a lower pipe one are installed at the end of one set of lower longitudinal pipes.

[0031] Compared with existing technologies, it has the following advantages:

[0032] 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. Furthermore, continuous feeding onto the cutting table does not affect the cutting accuracy of the laser cutting head due to vibrations generated during feeding.

[0033] This invention maintains water cooling for the cutting machine bed by setting up upper and lower water channels. The continuous increase in heat generated during high-power laser cutting is mitigated by the water-cooled return roller, reducing the likelihood of thermal deformation of the cutting machine bed.

[0054] 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.

[0055] Example 1

[0056] Please see Figure 1-6 This utility model provides a technical solution, including a water-cooled bed-type split laser cutting machine, which includes a cutting table 10 and a cutting machine bed 20, wherein the cutting table 10 and the cutting machine bed 20 are separately configured;

[0057] A crossbeam 30 is mounted on the cutting machine bed 20, and a laser cutting head 40 is mounted on the crossbeam 30. The crossbeam 30 moves on the cutting machine bed 20. The movement of the crossbeam on the cutting machine bed is achieved by a drive motor mounted at the bottom of the crossbeam, a gear mounted at the bottom of the drive motor, and a slide rail and rack mounted on the cutting machine bed. The rack meshes with the gear, and the slide rail restricts the crossbeam's axial movement along the slide rail. The sliding method is a conventional method. Figure 1 and Figure 2 Part of it has been drawn, but no enlarged details have been provided.

[0058] Cooling water channels are arranged inside the cutting machine bed 20. By having two layers of cooling water channels on the cutting machine bed, the temperature of the cutting machine bed is reduced, preventing deformation of the cutting machine bed due to heat generated during prolonged cutting use. The laser cutting machine may also include air pumps, control consoles, laser generators, transmission components, and dust removal systems, etc. This application does not describe the above structures; the structures mentioned above refer to existing laser cutter structures, and are not described in detail 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 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.

[0059] like Figure 1 As shown, the cutting table 10 is installed inside the cutting machine bed 20 and is arranged separately. The top height of the cutting table 10 is lower than the height of the crossbeam frame 30.

[0060] like Figure 3 As shown, 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, and the toothed plates 12 are used to support the workpiece.

[0061] Combination Figure 4 and 5 As shown, the working frame 11 includes a snap-fit ​​plate 13, within which a snap-fit ​​groove 14 is formed. 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 has a toothed shape. A ground support column 15 is installed at the bottom of the working frame 11, and adjustable feet 21 are installed at the bottom of the cutting machine bed 20. The cutting table and the cutting machine bed are each mounted on the ground via the ground support column and the adjustable feet. The snap-fit ​​groove connects to the toothed plate to keep the toothed plate facing upwards, with the toothed shape also facing upwards.

[0062] like Figure 2 As shown, the cutting machine bed 20 includes transverse columns 22 and longitudinal columns 23, which are distributed in a rectangular area; a reinforcing column 24 is provided between the two sets of longitudinal columns 23, and the reinforcing column 24 is arranged parallel to the transverse columns 22; the cutting table 10 is installed in the rectangular area enclosed by the transverse columns 22 and the longitudinal columns 23.

[0063] 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. Furthermore, continuous feeding onto the cutting table does not affect the cutting accuracy of the laser cutting head due to vibrations generated during feeding.

[0064] Example 2

[0065] like Figure 7-13 As shown, this is another embodiment of the present invention, based on embodiment 1, as follows: Figure 7 As shown, the cooling water circuit includes an upper water circuit 50 and a lower water circuit 60; the upper water circuit 50 and the lower water circuit 60 are located on the upper and lower sides of the longitudinal column 23, respectively.

[0066] like Figure 10 As shown, the upper waterway 50 includes two sets of upper longitudinal pipes 51 and two sets of upper transverse pipes 52. The upper longitudinal pipes 51 are installed parallel to each other on the upper side of the longitudinal column 23. The two sets of upper longitudinal pipes 51 are parallel and connected to the two sets of upper transverse pipes 52. An inlet is installed at the end of one set of upper longitudinal pipes 51 and an upper connecting pipe 53 is also installed thereon. Figure 10 The middle part is a bottom view of the crossbeam frame. Two sets of upper horizontal pipes 52 are set in parallel. The set of upper horizontal pipes 52 away from the water inlet is connected to the two sets of upper longitudinal pipes 51 respectively.

[0067] Another set of upper horizontal pipes 52 has an outlet 1 on the outer side of the end near the inlet 1, which is not connected to the upper vertical pipe 51 with the inlet 1, and the other end is connected to the corresponding upper vertical pipe 51.

[0068] An upper pipe 2 54 is installed on the water outlet 1; the upper pipe 1 53 and the upper pipe 2 54 are located on the same side of the cutting machine body 20. The upper horizontal pipe and the upper vertical pipe corresponding to the water outlet 1 and the water inlet 1 are not connected, but other connection points are connected to form a layout of cooling water in the pipes, covering a large area of ​​the cutting machine body.

[0069] like Figure 12 The lower water passage 60 includes two sets of lower longitudinal pipes 61 and two sets of lower transverse pipes 62. The lower longitudinal pipes 61 are installed parallel to each other on the lower side of the longitudinal column 23. The two sets of lower longitudinal pipes 61 are parallel and connected to the two sets of lower transverse pipes 62. A water inlet 2 is installed at the end of one set of lower longitudinal pipes 61 and a lower pipe 1 63 is installed thereon.

[0070] Two sets of lower horizontal pipes 62 are arranged in parallel, and the set of lower horizontal pipes 62 that is far away from the second inlet is connected to the two sets of lower vertical pipes 61 respectively.

[0071] Another set of lower horizontal pipes 62 has an outlet 2 on the outer side of the end near the inlet 2, which is not connected to the lower vertical pipe 61 with the inlet 2, and the other end is connected to the corresponding lower vertical pipe 61.

[0072] A lower pipe 2 64 is installed on the second water outlet; the lower pipe 1 63 and the lower pipe 2 64 are located on the same side of the cutting machine bed 20. Similar to the upper water channel, the lower water channel, which forms a closed loop, also covers a large area of ​​the cutting machine bed, and its proportion is higher than that of the upper water channel.

[0073] Considering that the inside of the pipes would corrode due to long-term contact with water, and that rust would contaminate the water chiller and laser, the pipes were internally galvanized for corrosion protection.

[0074] Among them, upper pipe one, upper pipe two, lower pipe one, and lower pipe two are all located on the same side of the cutting machine bed 20, such as Figure 8 As shown in the figure, the connection between the connecting pipe and the pipeline is not illustrated. It can be seen that the width of the upper longitudinal pipe 51 is smaller than the width of the lower longitudinal pipe 61, and the width of the upper transverse pipe 52 is smaller than the width of the lower transverse pipe 62. A protective pipe I is installed outside the upper longitudinal pipe, and slide rails are installed on both the protective pipe I and the upper longitudinal pipe. These slide rails are used to connect and guide the movement of the crossbeam frame. A protective pipe II, with the same dimensions as the lower longitudinal pipe, is installed at the bottom of the lower longitudinal pipe. Adjustable feet are installed at the bottom of the protective pipe II. The height of the cutting machine bed is adjusted via threaded connections.

[0075] like Figure 13 As shown, the laser cutting machine is externally equipped with a water chiller 70. The water chiller is a functional component that the laser cutting head needs to carry, primarily to maintain the operating temperature of the laser cutting machine and prevent power fluctuations or equipment damage due to overheating. Conventional water chillers 70 are equipped with an outlet pipe 71 and an inlet pipe 72; in this embodiment, a T-junction and pipes are used.

[0076] Simply add a tee and pipes to the inlet and outlet pipes to connect the corresponding pipes; no separate cooling device is needed, making it more environmentally friendly and energy-efficient. Upper pipe 1 53 and lower pipe 1 63 are both connected to the outlet pipe 71 via pipes; upper pipe 2 54 and lower pipe 2 64 are both connected to the inlet pipe 72 via pipes.

[0077] After placing the workpiece on the cutting table, the crossbeam is moved and the cutting path is set via the interactive interface of the control panel; the laser cutting head then cuts the workpiece. During operation, the water chiller is kept constantly on, ensuring the reciprocating circulation of cooling water between the upper and lower circuits, resulting in continuous cooling of the cutting machine bed and maintaining structural stability.

[0078] 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.
