Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, in particular to a hydraulic sheet metal laser cutting device. Background Art

[0002] Laser cutting is an advanced metal processing technology that uses a concentrated high-power, high-energy-density laser beam as a heat source, and irradiates the workpiece according to the designed cutting trajectory through computer-aided design and computer-aided manufacturing technology. Under the irradiation of the laser beam, the surface of the material will quickly melt, vaporize, ablate or reach the ignition point, and at the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby achieving cutting.

[0003] The basic principle of laser cutting is to irradiate the cutting area with a high-energy-density laser beam, causing the material surface to evaporate or melt, and at the same time forming a tiny slit on the material surface, thereby achieving the purpose of cutting. Under the action of the laser, due to the strong physical and chemical changes on the material surface, the processed material melts, evaporates or decomposes, and finally forms an incision. Laser cutting can cut complex shapes and fine features, with high cutting accuracy and good slit geometry. The laser cutter does not physically contact the material, so it does not cause deformation or stress, the workpiece deformation is small, the laser cutting incision is narrow, and the cutting surface is smooth and beautiful.

[0004] In laser cutting, oxidation and burning are prone to occur in the cutting area, causing the cutting surface to become rough and uneven, and even causing cracks, deformation and other problems. Therefore, spraying of protective gas is usually used in the laser cutting area to ensure the cutting effect. However, the protective gas in the prior art is usually sprayed directly on the cutting area through a pipe. This spraying method has a low spraying range. If multiple pipes are arranged around the cutting area, the gas loss is large and the cost is too high. Therefore, it does not meet the existing needs. We propose a hydraulic sheet metal laser cutting device. Summary of the invention

[0017] The present invention has the following beneficial effects: 1. The hydraulic sheet metal laser cutting device, through the design of the rotating component, allows the protective gas to be rotated and sprayed around the laser output head. The rotating drive motor drives the driving gear to start rotating, and the driving gear is meshed with a rotating gear ring, so the rotating gear starts to rotate around the laser output head. Since the thickness of the rotating gear ring is much greater than the driving gear, no matter how far the electric push rod controls the distance between the processing column and the plate, the driving gear can be meshed with the rotating gear ring to ensure the normal rotation movement. In addition, since the protective gas output component continuously provides protective gas, the protective gas is continuously sprayed around the laser output head. Through this design, it is possible to realize the rotational spraying of protective gas around the laser cutting. Compared with the prior art, this design uses one pipeline for spraying, and has the advantages of increasing the spraying range. Compared with the use of multiple pipelines, it has the advantages of energy saving and material saving. In addition, the design of the self-rotating connecting block in the rotating block and the inclined design of the protective gas output port can further expand the spraying range of the protective gas. Compared with the prior art, one pipeline is used for spraying, and has the advantages of energy saving and material saving.

[0018] 2. The hydraulic sheet metal laser cutting device can adjust the supply efficiency of the protective gas while adjusting the distance between the laser output head and the sheet through the design of the pressure regulating component. For cutting thicker sheets, it is necessary to control the processing column to slide upward through the electric push rod to increase the distance between the laser output head and the sheet. During this process, the adjusting connecting rod and the adjusting plate fixedly connected to the inner wall of the mounting shell will slide downward in the gas supply bin. At this time, the movable space in the gas supply bin is reduced. During the piston movement, the gas supply rate is controlled by the moving speed of the telescopic gas supply component and the cross-sectional area of ​​the gas supply bin, and the moving speed of the telescopic gas supply component is controlled by the gas supply push rod. Therefore, under the premise of ensuring that the power of the gas supply push rod remains unchanged, the gas supply rate can be reduced by reducing the cross-sectional area of ​​the gas supply bin. Conversely, through this design, the output rate of the protective gas can be adjusted while adjusting the distance between the laser output head and the sheet, thereby ensuring that when cutting thick plates, the laser energy can have more time to penetrate the material, preventing excessive gas flow from causing the cutting surface to become wider and affecting the cutting accuracy.

[0019] 3. The hydraulic sheet metal laser cutting device can further improve the cooling effect on the cutting area through the design of the cooling component. During the rotation of the self-rotating connecting block, due to the design of the track groove at the bottom of the self-rotating connecting block and the design of the piston spring in the piston chamber, the piston rod continuously moves up and down. Through this movement, gas can be continuously absorbed from the outside through the cooling output port, and the gas in the piston chamber can be ejected outward through the cooling output port. Through this design, the effect of jetting the cutting area can be effectively achieved, further improving the cooling effect on the cutting area, and effectively ensuring the cutting accuracy and cutting quality.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example 1: This example aims to promote the solution of the problem that in order to ensure that the plate in the cutting area will not be deformed during the laser cutting process, the protective gas is usually sprayed in the cutting area. However, the common spraying method is to use a pipe to spray directly on the cutting area. This spraying method has a limited coverage. Please refer to Figures 1 to 9 A hydraulic sheet metal laser cutting device comprises a mounting shell 1, in which a processing device 2 is mounted, the processing device 2 comprises an electric push rod 21 fixedly connected to the mounting shell 1, an output end of the electric push rod 21 is fixedly connected to a processing column 22, a laser output head 23 is mounted at the bottom of the processing column 22, and a rotating component 3 is mounted at the bottom of the processing column 22.

[0032] The rotating assembly 3 includes a rotating block 32 , in which a self-rotating assembly 5 is installed. The self-rotating assembly 5 includes a self-rotating connecting block 52 installed in the rotating block 32 , and a protective gas outlet 56 is installed at the bottom of the self-rotating connecting block 52 .

[0033] The mounting shell 1 provides support for the entire laser cutting device. The mounting shell 1 is connected to a robotic arm to achieve mobile cutting, and is controlled by a CNC machine tool to achieve precise cutting (the movement of the laser cutting is controlled by a CNC machine tool, and the structure involved in this step is prior art, so this solution is not described in detail for comparison).

[0034] The distance between the laser output head 23 at the bottom of the processing column 22 and the plate can be adjusted by driving the electric push rod 21. This distance is adjusted according to the thickness of the plate. The design of the rotating component 3 allows the protective gas to rotate and spray around the laser output head 23. The design of the self-rotating connecting block 52 in the rotating block 32 and the inclined design of the protective gas output port 56 can further expand the spraying range of the protective gas. Compared with the prior art, which uses one pipe for spraying, it has the advantage of increasing the spraying range. Compared with the use of multiple pipes, it has the advantage of saving energy and materials.

[0035] A rotating groove 31 is provided in the processing column 22 , a rotating block 32 is rotatably connected in the rotating groove 31 , an anti-slip block 34 is fixedly connected to the top of the rotating block 32 , and the anti-slip block 34 is slidably connected in the anti-slip groove 33 , and the anti-slip groove 33 is provided in the processing column 22 .

[0036] The outer wall of the rotating block 32 is fixedly connected with a rotating gear ring 35, and the rotating gear ring 35 is meshingly connected with a driving gear 36. The upper center of the driving gear 36 is fixedly connected with the output end of a rotating driving motor 37. The rotating driving motor 37 is fixedly connected to the bottom of a mounting plate 38, and the mounting plate 38 is fixedly connected to the outer wall of the mounting shell 1.

[0037] The mounting plate 38 provides an installation space for the rotary drive motor 37. The rotary drive motor 37 drives the drive gear 36 to start rotating, and the drive gear 36 is meshed with the rotating gear ring 35, so the rotating gear ring 35 starts to rotate around the laser output head 23. Since the thickness of the rotating gear ring 35 is much greater than the driving gear 36, no matter the distance between the electric push rod 21 and the processing column 22 and the plate, the driving gear 36 can be meshed with the rotating gear ring 35 to ensure the normal rotation movement. In addition, since the protective gas output component 4 continuously provides protective gas, the protective gas is continuously sprayed around the laser output head 23. Through this design, it is possible to realize the rotational spraying of protective gas around the laser cutting. Compared with the prior art, this design uses one pipeline for spraying, which has the advantage of increasing the spraying range, and compared with the use of multiple pipelines, it has the advantage of energy saving and material saving. The design of the anti-slip groove 33 and the anti-slip block 34 ensures that the rotating block 32 will not fall off during the rotation process.

[0038] A shielding gas output assembly 4 for providing shielding gas is provided in the processing column 22. The shielding gas output assembly 4 includes an air supply bin 41, a one-way air inlet pipe 42 and a one-way output pipe 43 which are opened in the processing column 22. The air supply bin 41, the rotating block 32 and the one-way output pipe 43 are interconnected. The end of the one-way air inlet pipe 42 away from the air supply bin 41 is connected to the air supply equipment, and the end of the one-way output pipe 43 away from the air supply bin 41 is connected to the transition bin 44. The transition bin 44 is opened in the processing column 22. The transition bin 44 is connected to a connecting channel 45. The connecting channel 45 is opened in the anti-slip block 34 and the rotating block 32.

[0039] The shielding gas output assembly 4 is used to provide shielding gas to the shielding gas output port 56, and under the drive of the pressure regulating assembly 6, the gas is ejected through the shielding gas output port 56. Since the gas supply equipment, the one-way air inlet pipe 42, the gas supply bin 41, the one-way output pipe 43, the transition bin 44, the connecting channel 45 and the self-rotating driving gear block 54 are connected in sequence, the shielding gas is transported to the shielding gas output port 56 through the above-mentioned channels, and under the drive of the pressure regulating assembly 6, the gas is ejected at a certain pressure. This design ensures the output of the shielding gas, and under the drive of the rotating assembly 3, the shielding gas is continuously ejected around the laser output head 23. Through this design, it is possible to realize the rotational spraying of shielding gas around the laser cutting. Compared with the prior art, this design uses one pipe for spraying, and has the advantage of increasing the spraying range. Compared with the use of multiple pipes, it has the advantage of energy saving and material saving. Moreover, through the continuous jetting of the shielding gas output port 56, the cutting area can also be cooled, thereby ensuring the cutting effect.

[0040] The rotation assembly 5 includes a rotation groove 51 opened in the rotating block 32, a rotation connecting block 52 is rotatably connected in the rotation groove 51, a rotation gear ring 53 is fixedly connected to the side wall of the rotation connecting block 52, the rotation gear ring 53 is meshingly connected to the rotation driving gear block 54, and the rotation driving gear block 54 is installed on the side of the processing column 22 close to the rotation groove 31.

[0041] A ventilation channel 55 is provided in the self-rotating gear ring 53 . The ventilation channel 55 is connected to the communication channel 45 . The bottom of the ventilation channel 55 is connected to a protective gas outlet 56 . The protective gas outlet 56 is fixedly connected to the bottom of the self-rotating gear ring 53 .

[0042] During the rotation of the rotating block 32 around the processing column 22, the rotating gear ring 53 and the rotating driving gear block 54 start to mesh and rotate. The rotating driving gear block 54 is installed in the processing column 22. Therefore, the rotating connecting block 52 starts to rotate in the rotating block 32 with its own central axis as the axis. Moreover, due to the inclined design of the protective gas outlet 56 at the bottom of the rotating connecting block 52, the spraying range can be further expanded through the rotation of the rotating connecting block 52, thereby further improving the protective effect of the protective gas on the cutting area.

[0043] Example 2: This example is intended to promote the solution of the problem that the ejection rate of the protective gas directly affects the processing accuracy of plates of different thicknesses. This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 A pressure regulating assembly 6 is provided in the air supply bin 41. The pressure regulating assembly 6 includes an adjusting plate 61 slidably connected in the air supply bin 41. An adjusting connecting rod 63 is fixedly connected to the top of the adjusting plate 61. The adjusting connecting rod 63 is slidably connected in an adjusting slot 62. The adjusting slot 62 is opened in the processing column 22.

[0044] An extrusion slot 64 is provided at the bottom of the adjusting plate 61, and an extrusion slider 65 is slidably connected in the extrusion slot 64. A telescopic air supply assembly 66 is installed at the bottom of the extrusion slider 65. The telescopic air supply assembly 66 includes a telescopic inner plate 662 fixedly connected to the bottom of the extrusion slider 65, the telescopic inner plate 662 is slidably connected in the telescopic outer plate 661, and an air supply push rod 67 is fixedly connected to one side of the telescopic outer plate 661. The air supply push rod 67 is installed in the air supply bin 41, the lower end of the telescopic outer plate 661 is flush with the bottom of the air supply bin 41, and the upper end of the telescopic inner plate 662 is aligned with the bottom of the adjusting plate 61.

[0045] The thickness of the material directly affects the optimal spacing between the laser cutting head and the plate. Generally speaking, thinner materials require a smaller spacing to ensure that the laser cutting head does not idle and cuts effectively. On the contrary, thicker materials require a larger spacing to ensure that the laser cutting head can move smoothly and cut effectively. When cutting thinner plates, oxygen or other protective gases, such as nitrogen, argon, etc., can be appropriately increased, depending on the cutting material and the required flow rate. This is because when cutting thin plates, laser energy is easier to penetrate the material. Increasing the gas flow rate can help better blow away the molten material and improve the cutting quality and efficiency. For thicker plates, the flow rate of the protective gas should be appropriately reduced. This is because when cutting thick plates, the laser energy takes more time to penetrate the material. If the gas flow rate is too large, it may cause the cutting surface to become wider and even affect the cutting accuracy. Therefore, the thicker the plate, the larger the spacing between the laser output head 23 and the plate, and the smaller the output rate required at this time. The thinner the plate, the smaller the spacing between the laser output head 23 and the plate, and the larger the output rate required at this time.

[0046] Since the mounting shell 1 is fixed in the robot arm, for cutting thicker plates, it is necessary to control the processing column 22 to slide upward through the electric push rod 21 to increase the distance between the laser output head 23 and the plate. During this process, the adjustment connecting rod 63 and the adjustment plate 61 fixedly connected to the inner wall of the mounting shell 1 will slide downward in the gas supply bin 41. At this time, the movable space in the gas supply bin 41 is reduced, and during the piston movement, the gas supply rate is controlled by the moving speed of the telescopic gas supply component 66 and the cross-sectional area of ​​the gas supply bin 41, and the moving speed of the telescopic gas supply component 66 is controlled by the gas supply push rod 67. Therefore, under the premise of ensuring that the power of the gas supply push rod 67 remains unchanged, the gas supply rate can be reduced by reducing the cross-sectional area of ​​the gas supply bin 41. Conversely, through this design, the output rate of the protective gas can be adjusted while adjusting the distance between the laser output head 23 and the plate, thereby ensuring that when cutting thick plates, the laser energy can have more time to penetrate the material, preventing the cutting surface from becoming wider due to excessive gas flow, affecting the cutting accuracy.

[0047] The design of the extrusion groove 64 and the extrusion slider 65 ensures that the telescopic air supply component 66 can slide in the air supply bin 41 under the drive of the air supply push rod 67. The telescopic design of the telescopic air supply component 66 ensures that the adjustment plate 61 can ensure the sealing of the extruded area when adjusting the volume of the extrusion area.

[0048] Example 3: This example is intended to solve the problem that cooling by spraying protective gas alone may result in poor cooling effect. This example is an explanation based on Example 2. For details, please refer to Figures 1 to 9 A cooling component 7 is provided in the rotating block 32, and the cooling component 7 includes a piston chamber 71 opened in the rotating block 32, a piston plate 72 is slidably connected in the piston chamber 71, a piston spring 76 is fixedly connected to the bottom of the piston plate 72, and a cooling output port 77 is connected to the bottom of the piston chamber 71, and the cooling output port 77 is installed at the bottom of the rotating block 32.

[0049] A piston rod 74 is fixedly connected to the upper surface of the piston plate 72 , and the piston rod 74 is slidably connected in the extrusion groove 73 , which is opened in the rotating block 32 , and the top end of the piston rod 74 is slidably connected in the track groove 75 , which is opened at the bottom of the rotating connecting block 52 .

[0050] During the rotation of the rotating connecting block 52, due to the design of the track groove 75 opened at the bottom of the rotating connecting block 52 and the design of the piston spring 76 in the piston chamber 71, the piston rod 74 continuously performs an up and down movement. Through this movement, it can continuously absorb gas from the outside through the cooling output port 77, and the gas in the piston chamber 71 can be ejected outward through the cooling output port 77. Through this design, the effect of jetting the cutting area can be effectively achieved, further improving the cooling effect on the cutting area, and effectively ensuring the cutting accuracy and cutting quality.

[0051] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
