Description

Technical Field

[0001] This application relates to the technical field of laser cutting, and particularly to a laser cutting device. Background Art

[0002] In the process of laser equipment cutting and processing, the current market demand for processing special-shaped pipes is gradually increasing. Similar to the "day"-shaped pipes, there are single-layer or multi-layer special-shaped pipes inside. Laser cutting is relatively difficult and requires the assistance of a sawing machine to achieve cutting. Sawing equipment has limitations in fine processing or complex contour cutting. When laser processing and saw blade sawing are performed on workpieces, the processing process often requires changing the processing equipment or transferring the workpiece, which greatly reduces the processing efficiency. In addition, a large amount of metal debris and dust are easily generated during the processing of sawing equipment and may enter the equipment interior, reducing the equipment life.

[0034] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the laser cutting equipment 100 provided in the embodiments of this application. Figure 2 This is a schematic diagram of the sawing module 30 provided in an embodiment of this application. The laser cutting equipment 100 provided in this embodiment of the application is used for processing workpieces to be processed. The laser cutting equipment 100 includes a body 10, a laser module 20, and a sawing module 30.

[0035] The workpiece to be processed is placed on the machine body 10. The machine body 10 serves as the basic frame of the entire equipment, supporting the laser module 20, the sawing module 30, and other functional components; therefore, the machine body 10 possesses sufficient strength and rigidity. A support platform 11 may be provided on the machine body 10, located below the laser module 20 and the sawing module 30. The support platform 11 is used to place the workpiece to be processed so that the laser module 20 and the sawing module 30 can process it. The workpiece to be processed includes, but is not limited to, pipes, profiles, and other shaped metal or non-metal workpieces. The support platform 11 can also move vertically relative to the machine body 10 to facilitate loading and unloading.

[0036] A waste collection device 12 may also be installed on the machine body 10, located below the support platform 11. During laser cutting and sawing, a large amount of waste, such as metal scraps and slag, is generated. The waste collection device 12 is used to collect this waste, maintaining a clean working environment and preventing waste accumulation from affecting the equipment. The waste collection device 12 may be equipped with casters for easy movement within the working area as needed.

[0037] The laser module 20 is mounted on the machine body 10 and is used for laser processing of the workpiece. The laser module 20 mainly consists of a laser generator 21 and a drive unit 22, such as... Figure 3 As shown, Figure 3 Another structural schematic diagram of the laser cutting equipment 100 provided for the implementation of this application. The laser generator 21 can be selected from fiber lasers, CO2 lasers, or ultraviolet lasers, etc., depending on the processing requirements, and there is no limitation here.

[0038] The drive unit 22 is connected to the laser generator 21 and is used to drive the laser generator 21 to move in order to perform laser processing on the workpiece. The drive unit 22 may include, but is not limited to, an X-axis movement component, a Y-axis movement component, and a Z-axis movement component.

[0039] The X-axis is parallel to the length of the machine body 10, the Y-axis is parallel to the width of the machine body 10, and the Z-axis is parallel to the height of the machine body 10. The X-axis moving component drives the laser generator 21 to move along the length of the machine body 10, the Y-axis moving component drives the laser generator 21 to move along the width of the machine body 10, and the Z-axis moving component drives the laser generator 21 to move along the height of the machine body 10. Both the X-axis and Y-axis moving components can use a servo motor to drive a ball screw and a linear guide rail structure to drive the laser generator 21 to complete linear or circular trajectory movements in the horizontal plane. The Z-axis moving component can be vertically adjusted by a cylinder or an electric lead screw to adjust the focal length between the laser generator 21 and the workpiece surface to be processed.

[0040] The sawing module 30 is located on the machine body 10. The sawing module 30 includes a drive assembly 31, a saw blade 32, and a protective cover 33. The drive assembly 31 is connected to the saw blade 32 and the protective cover 33. The drive assembly 31 is used to drive the saw blade 32 to move in order to saw the workpiece to be processed. The protective cover 33 forms an accommodating space 331. Part of the saw blade 32 is accommodated in the accommodating space 331, and part of it is set towards the workpiece to be processed.

[0041] The drive assembly 31 can drive the saw blade 32 to rotate along its own axis to saw the workpiece to be processed. In addition, the drive assembly 31 can also drive the saw blade 32 to move in the vertical direction to get closer to the workpiece for cutting or to move away from the workpiece after cutting so that the workpiece can be unloaded.

[0042] The protective cover 33 has a semi-enclosed structure and can be composed of a metal frame and a transparent protective plate. The protective cover 33 can be fixed to the outside of the drive assembly 31. The size of the accommodating space 331 of the protective cover 33 is adapted to the saw blade 32, capable of accommodating part of the saw blade 32's structure. Simultaneously, the accommodating space 331 has a suitable opening facing the workpiece to be processed. The portion of the saw blade 32 not accommodated extends through the opening to contact and cut the workpiece during operation. It should be noted that a gap exists between the protective cover 33 and the saw blade 32 within the accommodating space 331, which avoids interference with the rotation of the saw blade 32 and prevents metal chips and dust generated during sawing from splashing into the equipment.

[0043] The laser cutting equipment 100 provided in this application embodiment integrates a laser module 20 and a sawing module 30 into one unit, enabling combined laser cutting and sawing of workpieces. It can also flexibly switch between laser processing and saw blade 32 sawing methods depending on the workpiece and processing requirements, eliminating the need to change equipment or transfer workpieces, reducing process turnaround time and significantly improving processing efficiency. Part of the saw blade 32 is exposed for cutting, while the remaining part is housed within a protective cover 33. The protective cover 33 effectively prevents debris and dust generated during sawing from entering the drive assembly 31 or the laser module 20, avoiding wear and tear on the equipment's internal components.

[0044] Please see Figure 2 , Figure 4 and Figure 5 ,in, Figure 4 This is a schematic diagram of the structure of the protective cover 33 provided in the embodiment of this application. Figure 5 This is a structural schematic diagram of the protective cover 33 provided in an embodiment of this application from another perspective. Optionally, the protective cover 33 includes a body 332 and an exhaust pipe 333. An accommodating space 331 is formed on the body 332, and the exhaust pipe 333 is disposed on one side of the body 333 and communicates with the accommodating space 331.

[0045] Thus, during the sawing process, the accommodating space 331 provides physical protection, preventing debris generated during sawing from splashing into the laser cutting equipment 100 and causing wear. The exhaust pipe 333 can be connected to external dust removal equipment to suck out the dust generated during the sawing process and located in the accommodating space 331, ensuring a clean environment during the sawing process and preventing dust from adhering to the inside of the protective cover 33 for a long time, which would affect the normal operation of the saw blade 32.

[0046] The main body 332 may include a first housing and a second housing, which together form an accommodating space 331. The first housing and the second housing can be connected by a detachable connection method such as bolts or clips. The detachable connection structure facilitates installation, maintenance, and repair. For example, when replacing the saw blade 32, the saw blade 32 can be easily removed by simply disassembling either the first housing or the second housing. When cleaning debris attached to the accommodating space 331, the debris on the first housing, the second housing, and the saw blade 32 can be cleaned by simply disassembling either the first housing or the second housing.

[0047] The exhaust duct 333 is mounted on the main body 332. One end of the exhaust duct 333 is inserted into the accommodating space 331, and the other end is connected to an external dust removal system or exhaust device via a pipe. The dust removal system or exhaust device can directly suck the chips and dust generated by the saw blade 32 during sawing into the pipe, preventing chips and dust from splashing or accumulating in the accommodating space 331. It can also prevent chips from entering the laser module 20 or the drive assembly 31, thus avoiding affecting the normal operation of these components.

[0048] Optionally, the protective cover 33 also includes a baffle 334 installed on one side of the body 332. The baffle 334 has an opening 334a, which faces the saw blade 32 and is connected to the exhaust pipe 333. The baffle 334 is used to block the debris generated by the saw blade 32 sawing the workpiece to be processed.

[0049] In this way, some of the chips generated by the saw blade 32 cutting the workpiece can splash onto the baffle 334, and the exhaust pipe 333 can prevent the chips on the baffle 334 from accumulating through the suction pipe.

[0050] by Figure 2 Taking the current perspective as an example, when the saw blade 32 rotates clockwise, some of the debris generated when the saw blade 32 cuts the workpiece is thrown to the left rear of the body 332 along the tangential direction at the bottom of the saw blade 32. Therefore, a baffle 334 is provided on the left side of the body 332 to block some of the debris. The position of the baffle 334 can be set according to the rotation direction of the saw blade 32 and is not limited here. In addition, the exhaust pipe 333 can extract the debris from the baffle 334, and the opening 334a can increase the air intake of the exhaust pipe 333, thereby improving the dust removal efficiency.

[0051] Optionally, the drive assembly 31 includes a first rotary drive member 311, the output shaft of which is connected to the saw blade 32. The first rotary drive member 311 drives the saw blade 32 to rotate around its own axis to saw the workpiece. A first notch 332a is provided on the body 332 for mounting the first rotary drive member 311. Thus, mounting the first rotary drive member 311 on the first notch 332a of the body 332 makes the sawing module 30 structure more compact.

[0052] The main body 332 serves as the base of the protective cover 33 and can be directly connected and fixed to the drive assembly 31. The output shaft of the first rotary drive component 311 in the drive assembly 31 can be fixedly connected to the main body 332 and the center hole of the saw blade 32 through couplings, flanges, and other connecting parts. The first rotary drive component 311 transmits rotational power to the saw blade 32, driving the saw blade 32 to rotate at high speed around its own axis to achieve sawing of the workpiece.

[0053] To accommodate the installation of the first rotary drive component 311, a first notch 332a is provided on the main body 332. The size of the first notch 332a matches the shape of the first rotary drive component 311, ensuring that the first rotary drive component 311 can be securely embedded and guaranteeing the coaxiality of the output shaft of the first rotary drive component 311 and the saw blade 32. The shape of the first notch 332a can be circular, semi-circular, or square, etc., and the specific shape can be selected according to the installation requirements of the first rotary drive component 311, without limitation.

[0054] In one embodiment, when the first rotary drive 311 is a cylindrical servo motor, the first notch 332a is also a circular hole. The motor is embedded in the first notch 332a and then fixed from the outside of the body 332 by screws to ensure that the motor will not fall off during high-speed operation.

[0055] Please see Figure 6 , Figure 6 This is a schematic diagram of the sawing module provided in an embodiment of this application from another perspective. To ensure a more stable connection between the saw blade 32 and the output shaft of the first rotary drive 311, a pressure plate 335 is installed on the side of the saw blade 32 away from the first rotary drive 311, and the pressure plate 335 is bolted to the saw blade 32. The pressure plate 335 ensures that the saw blade 32 will not fall off the output shaft when the first rotary drive 311 drives the saw blade 32 to rotate.

[0056] Optionally, a second notch 332b is provided on the main body 332. The second notch 332b is positioned opposite to the first notch 332a, and the size of the second notch 332b is larger than that of the first notch 332a. The second notch 332b is located close to the pressure plate 335, which facilitates the installation and removal of the pressure plate 335. This allows operators to observe the sawing process and perform equipment maintenance. When the saw blade 32 becomes worn and needs to be replaced, the larger second notch 332b also provides maintenance personnel with more operating space, making it easier to disassemble the saw blade 32 and inspect the internal structure.

[0057] Optionally, the drive assembly 31 includes a first linear drive 312 mounted on the machine body 10. The first linear drive 312 is connected to the saw blade 32 via a bracket 35, and is used to drive the saw blade 32 to move vertically. Thus, the first linear drive 312 drives the saw blade 32 to move vertically, allowing the sawing module 30 to automatically adjust the cutting depth according to the workpiece thickness without manual adjustment.

[0058] Specifically, the first linear drive unit 312 integrates a power source and a transmission mechanism. The power source can be a servo motor, and the transmission mechanism can be a ball screw or linear guide with a synchronous belt. One end of the bracket 35 is fixedly connected to the transmission mechanism of the first linear drive unit 312, and the other end is connected to the saw blade 32. The bracket 35 can be made of high-strength metal materials, such as aluminum alloy or steel, and has good rigidity and stability to ensure that it will not deform during power transmission and will not affect the movement accuracy of the saw blade 32.

[0059] Before sawing begins, the first linear drive 312 drives the support 35 to move downward, so that the saw blade 32 gradually approaches the workpiece to be processed; after sawing is completed, in order to facilitate the unloading of the workpiece, the first linear drive 312 controls the support 35 to drive the saw blade 32 to move upward, so that the saw blade 32 moves away from the workpiece and returns to the initial position.

[0060] In some embodiments, the sawing module 30 may also include a limiting device disposed on the machine body 10. When the saw blade 32 moves to a set upper or lower limit position, the limiting device is activated to stop the action of the first linear drive member 312 in a timely manner, so as to prevent the saw blade 32 from being damaged due to excessive movement.

[0061] In one embodiment, the first linear drive 312 includes a servo motor, a linear guide rail, and a slider. The servo motor is mounted on the linear guide rail, which is vertically mounted on the machine body 10. One end of the bracket 35 is connected to the saw blade 32, and the other end is fixedly connected to the slider. The slider is tightly fitted onto the linear guide rail and can slide smoothly along it. When the servo motor starts, it drives the bracket 35 and the saw blade 32 to move vertically along the linear guide rail. During the rising or falling process, the linear guide rail provides guidance for the bracket 35, ensuring the accuracy of the saw blade 32's movement trajectory.

[0062] Optionally, the drive assembly 31 further includes a second rotary drive 313, which is mounted on the bracket 35 and is used to drive the bracket 35 to rotate in the vertical direction to drive the saw blade 32 to rotate.

[0063] Thus, the second rotary drive 313 drives the saw blade 32 to rotate, thereby adjusting the cutting angle of the saw blade 32 and enabling the sawing module 30 to cut the workpiece at multiple angles. When it is necessary to cut a bevel or a workpiece contour at a specific angle, the cutting direction of the saw blade 32 can be controlled simply by adjusting the rotation angle of the saw blade 32.

[0064] Specifically, the second rotary drive component 313 may include a servo motor and a reducer to ensure the stability and positioning accuracy of the saw blade 32 during rotation. The output shaft of the servo motor is connected to the input end of the reducer via a coupling, and the output end of the reducer is fixedly connected to the rotation shaft of the bracket 35 via a rotating flange 36. The saw blade 32 is mounted on the bracket 35. When the servo motor operates, the power is amplified by the reducer, and the speed is reduced before being transmitted to the bracket 35, driving the entire bracket 35 to rotate in the vertical direction. The rotation of the bracket 35 then drives the saw blade 32 to rotate synchronously.

[0065] Please see Figure 7 , Figure 7 This is another structural schematic diagram of the sawing module 30 provided in the embodiments of this application. Optionally, the sawing module 30 further includes a pressing assembly 34 mounted on the machine body 10. The pressing assembly 34 includes a second linear drive member 341 and a pressing plate 342 connected to the second linear drive member 341. The second linear drive member 341 is used to drive the pressing plate 342 to move in the vertical direction.

[0066] During the sawing process, the pressure plate 342, controlled by the second linear drive component 341, firmly presses the workpiece to be processed onto the support platform 11 of the machine body 10, preventing the workpiece from shifting, vibrating, or warping under the action of the cutting force, thereby affecting the processing accuracy.

[0067] The second linear drive unit 341 can be driven by a servo motor in conjunction with a ball screw, or it can be driven by a cylinder. Different drive methods can be used according to different needs, and no restrictions are imposed here.

[0068] The pressure plate 342 is the component that directly contacts the workpiece. The main structure of the pressure plate 342 can be made of high-strength aluminum alloy to ensure sufficient rigidity so that it is not easily broken when holding the workpiece. The surface of the pressure plate 342 that contacts the workpiece can be provided with a rubber anti-slip layer, which can effectively fix the workpiece and prevent scratches on the machined surface of the workpiece. The pressure plate 342 can be circular, rectangular or other irregular shapes.

[0069] Optionally, the sawing module 30 may also include a frame 37, on which a drive assembly 31 and a pressing assembly 34 may be mounted. The sawing module 30 may be mounted on the machine body 10 via the frame 37 for easy disassembly and installation.

[0070] Optionally, the laser cutting equipment 100 also includes a chuck 40 mounted on the machine body 10. The chuck 40 is used to hold the workpiece to be processed. A third rotary drive (not shown) is provided on the chuck 40 to drive the chuck 40 to rotate, thereby causing the workpiece to rotate about its own length. Thus, during the processing of the workpiece, after processing one surface, the third rotary drive drives the chuck 40 to rotate, thereby causing the workpiece to rotate to process the remaining surfaces. This eliminates the hassle of removing the workpiece from the equipment and aligning the workpiece to be processed with the laser module 20 or the sawing module 30, thus improving the processing speed.

[0071] The chuck 40 may include clamping components for holding the workpiece, typically a pneumatically or hydraulically driven three-jaw or four-jaw self-centering chuck. A servo motor, ball screw, and linear guide rail can be used to drive the chuck 40 to move along the length of the machine body 10. For example, the servo motor, as a power source, is directly connected to the ball screw via a coupling. The nut seat of the ball screw is connected to the chuck 40 via bolts. A slider is mounted on the chuck 40, and the slider cooperates with the linear guide rail fixed to the machine body 10, providing stable guiding support for the movement of the chuck 40. This allows the servo motor to drive the chuck 40 to move relative to the machine body 10 along its length, facilitating the processing of different parts of the workpiece by the laser module 20 and the sawing module 30.

[0072] Optionally, the chuck 40 is located below the laser module 20 and the sawing module 30, and the chuck 40 can move along the length of the machine body 10. The chuck 40 fixes the workpiece to be processed on the machine body 10 by clamping force, which facilitates the subsequent processing by the laser module 20 and the sawing module 30, ensuring that the workpiece will not be displaced, vibrated, or deflected during processing, thereby ensuring processing quality. When laser cutting is performed, the chuck 40 can move the workpiece to the optimal focusing position of the laser beam to ensure cutting quality. Optionally, there are at least two chucks 40, and at least two chucks 40 are spaced apart on the machine body 10 along the length of the machine body 10. In this way, multiple chucks 40 simultaneously clamp different parts of the workpiece, realizing the segmented clamping of the workpiece in one clamping.

[0073] In one implementation, there are two chucks 40, with the first chuck and the second chuck spaced apart along the length of the machine body 10. When the workpiece to be processed is a short tube, one end of the tube is clamped by the first chuck, and the other end passes through the second chuck and is also clamped by the second chuck.

[0074] In another embodiment, there are three chucks 40, with the first, second, and third chucks spaced apart along the length of the machine body 10. When the workpiece to be processed is a long pipe, the beginning, middle, and end of the pipe are clamped in sections by the first, second, and third chucks respectively, so that the pipe is stably fixed.

[0075] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
