Abstract
Description
Technical Field
[0001] This application relates to the field of metal cutting technology, and in particular to a laser cutting device for aluminum production and processing. Background Technology
[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the workpiece, rapidly heating the irradiated area to its melting or boiling point. Simultaneously, a high-pressure auxiliary gas (such as nitrogen) coaxial with the laser beam blows away the molten or vaporized material, creating a hole. As the relative position of the laser beam and the workpiece moves, a continuous kerf is eventually formed, thus cutting the workpiece.
[0003] Aluminum is a metal product made from aluminum as a base, with the addition of other alloying elements (such as copper, magnesium, silicon, zinc, etc.). It has the characteristics of being lightweight, high-strength, corrosion-resistant, easy to process, and having good electrical and thermal conductivity, and is widely used in industries such as construction and transportation. Laser cutting is an important step in the production and processing of aluminum materials, which can precisely cut aluminum materials (such as square tubes) into the required shapes and sizes, thus preparing them for subsequent bending, welding, and assembly.
[0004] Common laser cutting equipment includes a track machine tool, a drive mechanism that slides along the length of the track machine tool, a fixing mechanism that is fixed on the track machine tool, and a laser cutting head located above the track machine tool. The laser cutting head includes a laser generator, a laser nozzle, and an air jet module. The laser nozzle and the air jet module are coaxially arranged. When cutting aluminum workpieces, the aluminum workpiece is first transferred to the track machine tool and fixed by the drive mechanism and the fixing mechanism. Then, the laser cutting head is controlled to move to the starting point of the pre-designed cutting path. The laser generator then emits a laser beam to pierce the aluminum workpiece. The laser cutting head is then controlled to move along the pre-designed cutting path to achieve the cutting of the aluminum workpiece.
[0005] However, laser cutting equipment still has some drawbacks in use: First, during laser cutting, the two ends of the aluminum workpiece are located on both sides of the laser cutting head, and only one end of the aluminum workpiece is supported and fixed. Due to the high thermal conductivity and low rigidity of the aluminum workpiece, when the end of the aluminum workpiece is irradiated by the laser beam, the internal thermal stress of the aluminum workpiece accumulates, and its end is prone to warping and deformation, resulting in poor cutting quality of the aluminum workpiece. Second, during laser cutting, the pressure of high-pressure nitrogen gas is at its maximum when it is ejected. As the nitrogen gas flow moves, its pressure gradually decreases and its speed gradually slows down. Thus, when the nitrogen gas flow passes through the kerf, it can blow the liquid aluminum to the lower half of the kerf, but it cannot blow it away completely, causing the molten slag to adhere to the lower surface of the aluminum workpiece, resulting in poor cutting quality of the aluminum workpiece. Summary of the Invention
[0006] This application proposes a laser cutting equipment for aluminum production and processing, which has the advantages of effectively constraining the aluminum workpiece to prevent it from warping and deforming due to heat, and effectively increasing the pressure of the nitrogen gas flow to help blow away the molten slag from the aluminum workpiece, thereby solving the problem of poor cutting quality of aluminum workpieces caused by the above factors.
[0007] To achieve the above objectives, this application adopts the following technical solution: a laser cutting equipment for aluminum material production and processing, comprising: A cutting mechanism is fixedly mounted on a track machine tool, and an aluminum workpiece is placed below the cutting mechanism; A fixing mechanism is fixedly mounted on the track machine tool and is located on the right side of the cutting mechanism; A drive mechanism is slidably mounted on the track machine tool, and the drive mechanism is located to the right of the fixed mechanism; An auxiliary mechanism is slidably mounted on the track machine tool and located to the left of the cutting mechanism. The auxiliary mechanism includes an auxiliary component, a left rotating device, a pushing device, and a connecting device. The left rotating device is movably sleeved inside the auxiliary component. One end of the connecting device is embedded inside the left rotating device. During laser cutting, the other end of the connecting device passes through the cutting mechanism and extends into the interior of the fixing mechanism. At this time, one end of the aluminum workpiece is clamped and fixed by the driving mechanism, the middle part of the aluminum workpiece moves through the fixing mechanism, and the other end of the aluminum workpiece is sleeved and fixed by the connecting device. Thus, the connecting device is used to support and constrain the end of the aluminum workpiece.
[0008] Furthermore, the bottom end of the auxiliary component is provided with a sliding device, and the bottom end of the auxiliary component can slide on the track machine tool through the sliding device; The auxiliary component has a rotary device inside, and the rotary device is connected to the left rotary device in a transmission connection. The front half of the pushing device is a U-shaped plate and is movably connected to the connecting device. The rear half of the pushing device is a telescopic device and is movably connected to the left rotating device.
[0009] Furthermore, the cutting mechanism includes: The gantry frame is fixedly mounted on the track machine tool; A laser cutting head is movably mounted in the middle of the gantry frame.
[0010] Furthermore, the laser cutting head consists of a laser generator, a laser nozzle, and an air jet module. The laser generator is equipped with a laser nozzle and an air jet module at its bottom end, and the laser nozzle and air jet module are arranged coaxially.
[0011] Furthermore, the connecting device includes: A connecting plate, which is fixedly connected to the left rotating device by bolts; A connecting plate is fixedly connected to a connecting block on one side. A connecting rod, wherein the other side wall of the connecting block is fixedly connected to one end of the connecting rod; A connecting short block is formed, and the other end of the connecting rod is fixedly connected to one side wall of the connecting short block; The protective component has two ends that are fixedly connected to the connecting long block and the connecting short block by bolts, and the two protective components are spliced together on the outside of the connecting rod. The connecting rod has two symmetrically arranged rotating components.
[0012] Furthermore, the connecting long block and the connecting short block are located on both sides of the laser cutting head, and the connecting rod corresponds to the position of the laser cutting head; The connecting long block and the connecting short block have the same cross-section, and the exterior of the connecting long block and the connecting short block are adapted to the interior of the aluminum workpiece; The connecting rod is cylindrical in shape, and its diameter is shorter than the minimum width of the connecting block. The connecting rod has a connecting cavity inside and several connecting grooves on its outer side in the axial direction. The connecting rod has connecting holes in the radial direction, and the connecting holes connect the connecting cavity and the connecting grooves. Several connecting holes are provided on each connecting groove, and the several connecting holes are evenly arranged around the axis of the connecting cavity.
[0013] Furthermore, the surface of the protective component is coated with an anti-splash coating; The protective component has a sealed section and an open section, with the sealed section located at both ends of the open section. The working area of the jet module is located within the open section, and the working area of the rotating component is located within the sealed section. Both the open section and the sealed section have a number of air holes, and the number of air holes per unit area on the open section is greater than the number of air holes per unit area on the sealed section.
[0014] Furthermore, the rotating assembly includes: A rotary motor, which is fixedly installed inside the connecting long block or the connecting short block; A rotating shaft, one end of which is movably connected to a rotary motor; A rotating plate, with the other end of the rotating shaft fixedly connected to one side of the rotating plate; A rotating body is provided on the other side of the rotating plate, and the rotating body is trumpet-shaped; The rotating component consists of several arc-shaped rotating plates, and the rotating plate and the rotating body are fixedly connected by the rotating component. The rotating plate, the rotating body and the rotating component are located in the sealed section, and the space between the two rotating components corresponds to the position of the open section.
[0015] By designing the protective components, an anti-splatter coating is applied to their surface. This reduces the difficulty of peeling the molten aluminum off the components after it drips onto them and adheres to form slag. Secondly, the end of the connecting rod corresponds to the sealing section of the protective component, so the gas from the rotating assembly is rotated and discharged towards the sealing section of the protective component, effectively generating a vibration effect on the protective component and effectively cleaning the molten slag adhering to it. In addition, since the two protective components are spliced on the outside of the connecting rod and fixedly connected to the connecting long block and connecting short block by bolts, the old protective component can be disassembled and replaced with a new one if the molten slag on the protective component affects its normal use, and the operation is convenient.
[0016] Furthermore, the drive mechanism includes: The driving component has a sliding device at its bottom end, and the bottom end of the driving component can slide on the track machine tool through the sliding device. The drive component has a right-rotating device inside, which is movably sleeved and has a clamping device that can clamp and fix the end of the aluminum workpiece. The drive component has a rotary device inside, which is connected to the right-rotating device in a transmission manner.
[0017] Furthermore, the fixing mechanism includes: The fastener is fixedly connected to the track machine tool at its bottom end by bolts; The central rotating device is movably sleeved inside the fixed component, and the aluminum workpiece can pass through the interior of the central rotating device. Both ends of the central rotating device are provided with clamping devices, and the clamping devices can clamp and fix the middle part of the aluminum workpiece. The fixed component is provided with a rotary device inside, and the rotary device is connected to the central rotating device in a transmission manner.
[0018] The beneficial effects of this invention are as follows: This application provides a laser cutting equipment for aluminum production and processing. By setting a fixing mechanism and an auxiliary mechanism on both sides of the cutting mechanism, and the auxiliary mechanism includes an auxiliary component, a left rotation device, a pushing device, and a connecting device, the connecting device is inserted into the interior of the aluminum workpiece during the laser cutting process. This supports and constrains the end of the aluminum workpiece, ensuring the stability of the aluminum workpiece throughout the processing and preventing the end of the aluminum workpiece from warping or deforming due to heat, thus effectively improving the cutting quality of the aluminum workpiece.
[0019] By designing the connecting device, it is composed of a connecting long block, a connecting rod, a connecting short block, a protective component, and a rotating assembly. The connecting rod corresponds to the position of the laser cutting head. During laser cutting, the rotating assembly operates, generating gas flow within the connecting rod. The gas flow path is from the middle to the end of the connecting rod. Since the middle of the connecting rod corresponds to the open section of the protective component, the gas used by the rotating assembly comes from nitrogen injected by the jet module. This effectively enhances the gas pressure of nitrogen when passing through the cut of the aluminum workpiece, improves the penetration of the nitrogen gas flow, assists in blowing the liquid aluminum away from the aluminum workpiece, and prevents the formed slag from adhering to the lower surface of the aluminum workpiece, further improving the cutting quality of the aluminum workpiece. In addition, the nitrogen gas flow carrying heat moves within the aluminum workpiece due to the action of the rotating assembly, effectively reducing the temperature difference between the upper and lower surfaces of the aluminum workpiece, ensuring the thermal balance of the irradiated area of the aluminum workpiece, and effectively preventing the liquid aluminum from solidifying prematurely before being blown away.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0023] Example 1: A laser cutting device for aluminum material production and processing, such as... Figure 1 The system includes a track machine tool 1, on which an aluminum workpiece 2 is mounted. The aluminum workpiece 2 is driven by a driving mechanism 3, a fixing mechanism 4, a cutting mechanism 5, and an auxiliary mechanism 6. Specifically: like Figure 1 The cutting mechanism 5 is fixedly mounted on the track machine tool 1, and the aluminum workpiece 2 is positioned below the cutting mechanism 5. The cutting mechanism 5 is used to perform cutting operations on the aluminum workpiece 2. Figure 4 The cutting mechanism 5 includes a gantry frame 51 and a laser cutting head 52. The gantry frame 51 is fixedly mounted on the track machine tool 1, and a high-precision, high-speed three-dimensional motion platform is constructed in the middle of the gantry frame 51. The laser cutting head 52 is mounted on the three-dimensional motion platform, which allows the laser cutting head 52 to move precisely along a preset cutting trajectory to achieve directional cutting of the aluminum workpiece 2. Figure 5The laser cutting head 52 consists of a laser generator 521, a laser nozzle 522, and an air jet module 523. The laser nozzle 522 and the air jet module 523 are located at the bottom of the laser generator 521 and are coaxially arranged. When cutting the aluminum workpiece 2, the laser generator 521 emits a laser beam, which is focused and emitted by the laser nozzle 522, so that the laser beam accurately irradiates the surface of the aluminum workpiece 2. The light energy is instantly converted into heat energy, which increases the temperature of the irradiated area of the aluminum workpiece 2. The temperature rises sharply, exceeding its melting point, forming liquid aluminum, thus creating a slit in the aluminum workpiece 2. At the same time, the jet module 523 ejects high-pressure nitrogen gas, which assists the laser beam in its operation. This high-pressure gas flow can both blow the molten liquid aluminum away from the slit to form a cut and prevent the aluminum workpiece 2 from reacting with oxygen in the air at high temperatures, thus protecting the cut. It should be noted that the laser cutting head 52 needs to be adjusted to concentrate the laser energy in the lower middle part of the thickness of the aluminum workpiece 2, which helps the liquid aluminum to drain downwards.
[0024] like Figure 1 The fixing mechanism 4 is fixedly mounted on the track machine tool 1, and is located to the right of the cutting mechanism 5. The fixing mechanism 4 is used to fix the aluminum workpiece 2, such as... Figure 2 and Figure 4 The fixing mechanism 4 includes a fixing member 41 and a central rotating device 42. The bottom end of the fixing member 41 is fixedly connected to the track machine tool 1 by bolts. The central rotating device 42 is movably sleeved inside the fixing member 41, and the aluminum workpiece 2 can pass through the interior of the central rotating device 42. Both ends of the central rotating device 42 are provided with clamping devices, and the clamping devices can clamp and fix the middle part of the aluminum workpiece 2, effectively ensuring the stability of the aluminum workpiece 2 during the processing. The fixing member 41 is provided with a rotary device, and the rotary device is connected to the central rotating device 42 for transmission, so that the rotary device can drive the central rotating device 42 to generate self-rotation, thereby pushing the aluminum workpiece 2 to rotate.
[0025] like Figure 1 The drive mechanism 3 is slidably mounted on the track machine tool 1, and is located to the right of the fixed mechanism 4. The drive mechanism 3 is used to drive the aluminum workpiece 2, such as... Figure 2 and Figure 4The drive mechanism 3 includes a drive component 31 and a right rotation device 32. The bottom end of the drive component 31 is provided with a sliding device, and the bottom end of the drive component 31 can slide on the track machine tool 1 through the sliding device. The right rotation device 32 is movably sleeved inside the drive component 31, and the right rotation device 32 is provided with a clamping device, which can clamp and fix the end of the aluminum workpiece 2, effectively ensuring the stability of the aluminum workpiece 2 during the processing. The drive component 31 is provided with a rotary device, and the rotary device is connected to the right rotation device 32 through a transmission, so that the rotary device can drive the right rotation device 32 to generate self-rotation, thereby synchronously pushing the aluminum workpiece 2 to rotate.
[0026] like Figure 1 The auxiliary mechanism 6 is slidably mounted on the track machine tool 1, and is located to the left of the cutting mechanism 5. The auxiliary mechanism 6 is used to constrain the aluminum workpiece 2, such as... Figure 2 , Figure 6 and Figure 7 The auxiliary mechanism 6 includes an auxiliary component 61, a left rotating device 62, a pushing device 63, and a connecting device 7. The bottom end of the auxiliary component 61 is equipped with a sliding device, allowing it to slide on the track machine tool 1. The left rotating device 62 is movably sleeved inside the auxiliary component 61. A rotary device is also located inside the auxiliary component 61, and this rotary device is connected to the left rotating device 62 via a transmission connection. This allows the rotary device to drive the left rotating device 62 to rotate, ensuring that the left rotating device 62, right rotating device 32, and middle rotating device 42 rotate synchronously. This achieves synchronous rotation of the aluminum workpiece 2 and the connecting device 7, improving the stability of the aluminum workpiece 2 during operation. One end of the connecting device 7 is embedded inside the left rotating device 62, and during laser cutting, the other end of the connecting device 7 passes through the cutting edge. The cutting mechanism 5 extends into the fixed mechanism 4. At this time, one end of the aluminum workpiece 2 is clamped and fixed by the driving mechanism 3, the middle part of the aluminum workpiece 2 moves through the fixed mechanism 4, and the other end of the aluminum workpiece 2 is sleeved and fixed by the connecting device 7. Thus, the connecting device 7 is used to support and constrain the end of the aluminum workpiece 2, which not only ensures the stability of the aluminum workpiece 2 during the entire processing, but also prevents the end of the aluminum workpiece 2 from warping and deforming due to heat, effectively improving the cutting quality of the aluminum workpiece 2. The front half of the pushing device 63 is a "U"-shaped plate and is movably sleeved with the connecting device 7. The rear half of the pushing device 63 is a telescopic device and is movably connected with the left rotating device 62. The telescopic device pushes the "U"-shaped plate to move horizontally, which can help the cut aluminum workpiece 2 to get off the connecting device 7.
[0027] In summary, the control system drives the drive mechanism 3 to move horizontally along the track machine tool 1, pushing the aluminum workpiece 2 through the fixing mechanism 4, so that the aluminum workpiece 2 is cut from a long tube into several short tubes by the cutting mechanism 5. The specific operation to form a short tube is as follows: before cutting, the control system drives the auxiliary component 61 to move closer to the cutting mechanism 5, so that the connecting device 7 is sleeved with the end of the long tube before cutting. During cutting, the drive mechanism 3 and the fixing mechanism 4 control the movement of the long tube, and the cutting mechanism 5 performs laser cutting on its surface, thereby cutting a short tube from the end of the long tube. The short tube is sleeved on the connecting device 7 under the push of the drive mechanism 3. After cutting, the control system drives the auxiliary component 61 to move away from the cutting mechanism 5, and then the connecting device 7 is disengaged from the cut short tube under the action of the pushing device 63. This process is repeated.
[0028] Example 2, based on Example 1, such as Figure 6 and Figure 7 The connecting device 7 includes a connecting plate 71, a connecting long block 72, a connecting rod 73, a connecting short block 74, a protective component 8, and a rotating assembly 9, specifically: like Figure 3 , Figure 8 and Figure 9 The connecting plate 71 is fixedly connected to the left rotating device 62 by bolts. One side wall of the connecting plate 71 is fixedly connected to one side wall of the connecting long block 72, and the other side wall of the connecting long block 72 is fixedly connected to one end of the connecting rod 73. The other end of the connecting rod 73 is fixedly connected to one side wall of the connecting short block 74. The connecting long block 72 and the connecting short block 74 are located on both sides of the laser cutting head 52, and the connecting rod 73 corresponds to the position of the laser cutting head 52. That is, the connecting rod 73 and its internal components face the working area of the laser cutting head 52 to accurately assist in the irradiation area of the aluminum workpiece 2, thereby improving the cutting quality of the aluminum workpiece 2. The connecting long block 72 and the connecting short block 74 have the same cross-section, and the exterior of the connecting long block 72 and the connecting short block 74 are adapted to the interior of the aluminum workpiece 2, thus enabling the connecting long block 72 and the connecting short block 74 to achieve the desired cutting quality. Together, they provide support to the end of the aluminum workpiece 2. As laser cutting proceeds, driven by the drive mechanism 3, the post-cutting area of the aluminum workpiece 2 moves towards the connecting block 72, which then constrains it, preventing the aluminum workpiece 2 from warping or deforming due to heat. The connecting rod 73 is cylindrical, and its diameter is shorter than the minimum width of the connecting block 72, providing space for slag accumulation. The connecting rod 73 has a connecting cavity inside and several connecting grooves on its outer side in the axial direction. Connecting holes are radially formed on the connecting rod 73, connecting the cavity and the connecting grooves. Several connecting holes are correspondingly arranged on each connecting groove, and these holes are evenly arranged around the axis of the connecting cavity, thus facilitating the uniform movement of nitrogen gas inside and outside the connecting rod 73.
[0029] like Figure 3 and Figure 8 The two ends of the protective component 8 are fixedly connected to the connecting long block 72 and the connecting short block 74 respectively by bolts. There are two protective components 8, and the two protective components 8 are spliced on the outside of the connecting rod 73. The protective components 8 are used to receive molten slag, prevent molten slag from affecting the use of the connecting rod 73, and improve the service life of the connecting rod 73 and its internal components. The surface of the protective component 8 is coated with an anti-splatter coating, which helps the molten slag to be peeled off from the protective component 8. The protective component 8 has a sealing section and an open section, and the sealing section is located at both ends of the open section. The working area of the jet module 523 is located in the open section, and the working area of the rotating component 9 is located in the sealing section. Both the open section and the sealing section are provided with a number of air holes, and the number of air holes per unit area on the open section is greater than that on the sealing section. The large number of pores on the protective component 8 allows the nitrogen carrying heat to move around the protective component 8, effectively reducing the temperature difference between the upper and lower surfaces of the aluminum workpiece 2 and ensuring the thermal balance of the irradiated area of the aluminum workpiece 2. This prevents the liquid aluminum from solidifying prematurely before it is blown away. In addition, since the airflow enters the protective component 8 through the open section and exits through the sealed section, the design of the number of pores in the sealed and open sections can both increase the pressurization effect of the nitrogen airflow from the jet module 523 during air intake to improve the penetration of the nitrogen airflow and assist in blowing the liquid aluminum away from the aluminum workpiece 2, and increase the impact effect on the protective component 8 during exhaust to generate a vibration effect on the protective component 8, thereby partially cleaning the slag on the protective component 8.
[0030] like Figure 9 The connecting rod 73 has two symmetrically arranged rotating components 9 inside. These rotating components 9 help improve the cutting quality of the aluminum workpiece 2, such as... Figure 3 and Figure 10The rotating assembly 9 includes a rotating motor 91, a rotating shaft 92, a rotating plate 93, a rotating body 94, and a rotating component 95. The rotating motor 91 is fixedly disposed inside the connecting long block 72 or the connecting short block 74. One end of the rotating shaft 92 is movably connected to the rotating motor 91, and the other end of the rotating shaft 92 is fixedly connected to one side of the rotating plate 93. The rotating body 94 is disposed on the other side of the rotating plate 93 and is trumpet-shaped. The rotating component 95 is composed of several arc-shaped rotating plates, and the rotating plate 93 and the rotating body 94 are fixedly connected by the rotating component 95. Specifically, the front end of the rotating component 95 is fixedly sleeved with the inner wall of the rotating body 94, and the rear end of the rotating component 95 is fixedly sleeved with the wall of the rotating plate 93. The rotating plate 93, rotating body 94, and rotating component 95 are fixedly connected, so that centrifugal force is generated when they rotate at high speed, which helps to form a gas flow along the moving direction of the rotating component 95. The rotating plate 93, rotating body 94, and rotating component 95 are located in the sealed section, and the space between the two rotating components 95 corresponds to the position of the open section. When the rotating motor 91 is started, it drives the rotating shaft 92, rotating plate 93, rotating body 94, and rotating component 95 to rotate synchronously, so as to push the nitrogen gas to move in the connecting rod 73 and make the flow path of the nitrogen gas from the middle of the connecting rod 73 to the end of the connecting rod 73. Thus, the flow of nitrogen gas can achieve a variety of effects to improve the cutting quality of the aluminum workpiece 2.
[0031] The working principle of this invention is as follows: The entire aluminum workpiece 2 is transferred to the track machine tool 1, and the right end of the aluminum workpiece 2 is clamped and fixed by the drive mechanism 3, so that the left end of the aluminum workpiece 2 passes through the fixing mechanism 4 and is located below the cutting mechanism 5. Before cutting, the control auxiliary component 61 is brought close to the cutting mechanism 5 so that the connecting device 7 is inserted into the left end of the aluminum workpiece 2. During cutting, as the drive mechanism 3 pushes, this end of the aluminum workpiece 2 is gradually laser-cut by the cutting mechanism 5. After cutting, the cut aluminum workpiece 2 is sleeved on the connecting device 7. At this time, the control auxiliary component 61 is moved away from the cutting mechanism 5 so that the connecting device 7 is disengaged from the left end of the aluminum workpiece 2. Then the pushing device 63 works to disengage the cut aluminum workpiece 2 from the connecting device 7. The above operation is repeated until the entire aluminum workpiece 2 is completely cut.
[0032] During the laser cutting process, the post-cut area of the aluminum workpiece 2 is effectively constrained by the connecting short block 74 due to the pushing action of the drive mechanism 3, thereby preventing the end of the aluminum workpiece 2 from warping and deforming due to heat, and effectively improving the cutting quality of the aluminum workpiece 2.
[0033] During the laser cutting process, the working area of the laser cutting head 52 always corresponds to the connecting cavity located between the two rotating components 9. At this time, the rotating motor 91 is started, causing the rotating shaft 92 to drive the rotating plate 93, the rotating body 94, and the rotating component 95 to rotate at high speed. Under the centrifugal force of the rotating components 9, the airflow is pushed to move in one direction, thereby causing the gas used by the rotating components 9 to come from the nitrogen gas sprayed by the jet module 523. Specifically, under the action of the rotating components 9, the nitrogen gas enters the connecting rod 73 from the open section of the protective component 8 and is discharged to the outside of the connecting rod 73 from the sealed section of the protective component 8. This effectively enhances the gas pressure of the nitrogen gas flow when passing through the cut of the aluminum workpiece 2, improves the penetration of the nitrogen gas flow, assists in blowing the liquid aluminum away from the aluminum workpiece 2, prevents the formed slag from adhering to the lower surface of the aluminum workpiece 2, and further improves the cutting quality of the aluminum workpiece 2. It also effectively generates a vibration effect on the protective component 8, realizing the effective cleaning of some of the slag adhering to the protective component 8, so as to extend the service life of the protective component 8.
[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
