Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically to a laser cutting equipment and process for irregularly shaped metal components. Background Technology

[0002] Laser cutting equipment for irregularly shaped metal profiles is a core specialized piece of equipment in the field of precision metal processing. Utilizing laser cutting technology, it completes various forming processes such as hole cutting, line cutting, and segmented cutting of irregularly shaped metal profiles. It is primarily used for the precise cutting and shaping of various non-standard and irregularly shaped metal profiles. This equipment employs a mechanical positioning structure in conjunction with laser cutting components for automated processing, avoiding the deformation and burr problems of traditional mechanical cutting, ensuring the processing accuracy of irregularly shaped profiles, and adapting to the forming and processing needs of various irregularly shaped metal components. It is widely used in industrial production scenarios such as steel structures and hardware components.

[0003] Existing laser cutting equipment for irregularly shaped metal profiles suffers from numerous technical shortcomings. Conventional limiting structures have poor adaptability, failing to accommodate profiles of varying sizes and cross-sectional shapes. After segmented cutting, achieving stable multi-point limiting is difficult, leading to issues such as processing posture deviation and positioning loosening. In situations involving short, thin-edged profile ends, existing equipment lacks targeted edge-clamping limiting structures, causing short processing segments to easily suspend in mid-air. After cutting, these segments fall freely, easily causing component breakage and deformation. Furthermore, traditional equipment often employs rigid unloading methods such as vertical drop or ramps, making the profiles susceptible to hard impact damage. Unloading and cutting operations cannot be performed simultaneously, resulting in poor process continuity and significantly reducing the profile processing yield and overall processing efficiency, making it difficult to meet the batch processing needs of multi-specification, high-precision irregularly shaped metal profiles. Summary of the Invention

[0004] The purpose of this invention is to solve the compatibility problem of the limiting structure for irregularly shaped profiles, and to design a thin-edge limiting structure and provide a flexible unloading method. To achieve the above objectives, this invention adopts the following technical solution: A laser cutting device for irregularly shaped metal components includes an operating table and a laser cutter. The laser cutter is installed on the operating table and is used to laser cut the profile. A support assembly is provided on the operating table. The support assembly includes a material guiding component, six supporting components, and two clamping components. The material guiding component includes a linear guide rail and a carrier plate. The linear guide rail is installed on the operating table, and the carrier plate is located at the bottom of the linear guide rail. The carrier plate is used to support the cut profile. Multiple tension springs are provided at the bottom of the carrier plate to assist the carrier plate in adapting to profiles of different diameters.

[0005] Six supporting components are arranged in a straight line on the linear guide rail. Each supporting component includes a bracket plate, which is sleeved on the linear guide rail. The bracket plate is eccentrically installed on the linear guide rail and can move along the axial direction of the linear guide rail and rotate around it. Two sets of four pressure plates are staggered on the bracket plate. The two sets of pressure plates are distributed in an overlapping manner, and the four pressure plates are distributed in a ring. The pressure plates are used to limit and push the profile.

[0006] Two clamping components are respectively set on two support components located in the middle. The clamping components include four electric push rods, which are arranged in a ring. The telescopic shaft ends of the four electric push rods face one side of the corresponding bracket plate. The electric push rods are used to adjust the clamping position of the profile. Each electric push rod has two clamping plates at its telescopic shaft end. The clamping plates are used to clamp the inner and outer walls of the profile.

[0007] Furthermore, the material guiding component also includes a base, which is fixedly connected to the operating table. Multiple guide rods are slidably connected to the top of the base. The top ends of the multiple guide rods are fixedly connected to the lower surface of the carrier plate. Multiple tension springs are respectively sleeved on a guide rod. The bottom ends of the multiple guide rods are fixedly connected to a sliding plate, which is slidably connected to the base.

[0008] Furthermore, the support components also include a rotating plate one, which is mounted on a linear guide rail. A bracket plate is mounted on the rotating plate one. A rotating plate two is mounted on the end of the bracket plate away from the rotating plate one. Four pressure plates are arranged in a ring around the rotating plate two. Four telescopic rods are fixedly connected in a ring array on the rotating plate two. The telescopic shaft ends of the telescopic rods face the center of the rotating plate two. Each of the four telescopic rods is fixedly connected to a pressure plate.

[0009] Furthermore, the clamping component also includes two leveling rods, which are fixedly connected to the two closest to the rotating plate two of the four pressure plates. Two of the four electric push rods are fixedly connected to the leveling rods, and the other two electric push rods are fixedly connected to the pressure plates. Each of the four electric push rods has a frame fixedly connected to its telescopic shaft end. Each of the four frames has a guide groove on the side away from the electric push rod. The two clamping plates on the same electric push rod are slidably connected to the corresponding guide groove. Each of the four frames has an electric push rod two fixedly connected inside, and the electric push rod two and the corresponding clamping plate are distributed perpendicularly to each other. Each of the four electric push rod two has a guide plate fixedly connected to its telescopic shaft end. The guide plate is slidably connected to the inner wall of the corresponding frame. Each of the four guide plates has two symmetrical sliding grooves. Each clamping plate has a sliding shaft fixedly connected to one end inside the frame. The sliding shaft is slidably connected to the sliding groove.

[0010] Furthermore, the six supporting components are evenly distributed on both sides of the laser cutter as the center.

[0011] Furthermore, the carrier plate is located on the path of the profile being rotated downwards by the support plate.

[0012] Furthermore, the guide plate is L-shaped, and the chute is inclined on the guide plate.

[0013] A laser cutting process for irregularly shaped metal components includes the following steps:

[0014] Step 1: Insert the profile into the rectangular passage formed by multiple pressure plates, drive the telescopic rod to move the pressure plates inward until the electric drive rollers press against the outer wall of the profile, thus completing the limiting and alignment;

[0015] Step 2: Start the laser cutter to cut. During the process, the drive plate 2 drives the profile to rotate and moves in conjunction with the electric drive rollers to adjust the position and angle of the profile in real time to ensure the cutting trajectory is accurate.

[0016] Step 3: After the profile is completely cut into multiple segments, each segment is limited by the corresponding support components. Relying on the cooperation of linear guide rails and electric drive rollers, each segment is moved to the laser cutter for processing in sequence.

[0017] Step 4: When the remaining profile length is insufficient, activate the clamping components: Electric push rod one extends, and electric push rod two drives the two clamping plates to come together, clamping the inner and outer walls of the profile respectively to prevent it from falling and being damaged during cutting.

[0018] Further, in step five: the processed profile is rotated downwards by the support plate, squeezing the carrier plate and compressing the tension spring to flexibly support it; then the telescopic rod retracts to release the pressure plate, the support plate moves away, and the profile remains on the carrier plate to complete the unloading.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] By combining a ring-shaped multi-point adjustable pressure plate with multiple support components, a stable clamping mechanism is achieved for profiles with any complex cross-section across a long span. The profile will not shift, twist, or vibrate during the cutting process. At the same time, with the electric rollers on the pressure plate and the self-rotation function of the rotating plate, the position and angle of the profile can be adjusted in real time to ensure that the laser cutter is always aligned with the optimal processing trajectory, thereby obtaining high-precision cuts and dimensions.

[0021] The design of clamping components simultaneously holding the inner and outer walls of the profile ensures that even very short profile segments or small pieces of workpiece can be firmly fixed, preventing edge chipping, surface scratches, or workpiece scrap caused by falling.

[0022] By using a flexible support structure with a carrier plate and tension spring, combined with the rotating material feeding action of the support components, the unloading process of the profile is placed rather than thrown, avoiding the hard collision in the traditional material feeding method, effectively maintaining the smoothness of the processed surface and the overall appearance of the profile, and reducing subsequent finishing processes.

[0037] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0038] Example 1:

[0039] Reference Figures 1 to 10 As shown, a laser cutting equipment for irregularly shaped metal components includes an operating table 11 and a laser cutter 12. The laser cutter 12 is installed on the operating table 11 and is used to laser cut the profile 13.

[0040] The operating table 11 is equipped with a support assembly, which includes a material guiding component, six supporting components and two clamping components. The material guiding component includes a linear guide rail 21 and a carrier plate 29. The linear guide rail 21 is installed on the operating table 11, and the carrier plate 29 is set at the bottom of the linear guide rail 21. The carrier plate 29 is used to support the cut profile 13. Multiple tension springs 211 are set at the bottom of the carrier plate 29. The tension springs 211 are used to assist the carrier plate 29 in adapting to profiles 13 of different diameters.

[0041] Six supporting components are arranged in a straight line on the linear guide rail 21. Each supporting component includes a bracket plate 22, which is sleeved on the linear guide rail 21. The bracket plate 22 is eccentrically mounted on the linear guide rail 21. The bracket plate 22 can move along the axial direction of the linear guide rail 21 and can rotate around the linear guide rail 21. Two sets of four pressure plates 26 are staggered on the bracket plate 22. The two sets of pressure plates 26 are distributed in an overlapping manner, and the four pressure plates 26 are distributed in a ring. The pressure plates 26 are used to limit and push the profile 13.

[0042] Two clamping components are respectively set on two support components located in the middle. The clamping components include four electric push rods 31. The four electric push rods 31 are arranged in a ring. The telescopic shaft ends of the four electric push rods 31 face one side of the corresponding bracket plate 22. The electric push rods 31 are used to adjust the clamping position of the profile 13. Each electric push rod 31 has two clamping plates 34 at its telescopic shaft end. The clamping plates 34 are used to clamp the inner and outer walls of the profile 13.

[0043] The material guiding component also includes a base 27, which is fixedly connected to the operating table 11. Multiple guide rods 28 are slidably connected to the top of the base 27. The top ends of the multiple guide rods 28 are fixedly connected to the lower surface of the carrier plate 29. Multiple tension springs 211 are respectively sleeved on a guide rod 28. The bottom ends of the multiple guide rods 28 are fixedly connected to a slide plate 210, which is slidably connected to the base 27.

[0044] The supporting components also include a rotating plate 23, which is mounted on the linear guide rail 21. A bracket plate 22 is mounted on the rotating plate 23. A rotating plate 24 is mounted on the end of the bracket plate 22 away from the rotating plate 23. Four pressure plates 26 are arranged in a ring around the rotating plate 24. Four telescopic rods 25 are fixedly connected in a ring array on the rotating plate 24. The telescopic shaft ends of the telescopic rods 25 face the center of the rotating plate 24. Each of the four telescopic rods 25 is fixedly connected to a pressure plate 26.

[0045] The clamping component also includes two leveling rods 39, which are fixedly connected to the two pressure plates 26 closest to the rotating plate 24. Two of the four electric push rods 31 are fixedly connected to the leveling rods 39, and the other two electric push rods 31 are fixedly connected to the pressure plates 26. Each of the four electric push rods 31 has a carrier frame 32 fixedly connected to its telescopic shaft end. Each of the four carrier frames 32 has a guide groove 33 on the side away from the electric push rod 31. The two clamping plates 34 on the same electric push rod 31 are both connected to... The corresponding guide groove 33 is slidably connected. Each of the four frames 32 is fixedly connected to an electric push rod 35. The electric push rod 35 and the corresponding clamping plate 34 are distributed perpendicularly to each other. Each electric push rod 35 is fixedly connected to a guide plate 36 at the telescopic shaft end. The guide plate 36 is slidably connected to the inner wall of the corresponding frame 32. Two sliding grooves 37 are symmetrically opened on each of the four guide plates 36. Each clamping plate 34 is fixedly connected to a sliding shaft 38 at one end inside the frame 32. The sliding shaft 38 is slidably connected to the sliding groove 37.

[0046] Wherein: Rotating plate 23 is driven to be mounted on linear guide rail 21, and rotating plate 23 can drive support plate 22 to move along the axial direction of linear guide rail 21. Rotating plate 23 and linear guide rail 21 constitute a linear motion module in the prior art; support plate 22 is driven to be mounted on rotating plate 23, and support plate 22 can rotate around rotating plate 23; rotating plate 24 is driven to be mounted on support plate 22, and rotating plate 24 can rotate on support plate 22.

[0047] It should be noted that the rotary drive installation of bracket plate 22 and rotating plate 1 23, and the rotary drive installation of rotating plate 24 and bracket plate 22 are both achieved through the pulley chain transmission connection in the prior art. The drive source is the hydraulic cylinder or motor in the prior art. This is the prior art and will not be described in detail here.

[0048] Among them, the four pressure plates 26 on the same rotating plate 24 can form a rectangular channel of any shape under the telescopic control of the corresponding telescopic rod 25, so as to adapt to profiles 13 of different sizes. Each pressure plate 26 is provided with an electric drive roller on the side away from the telescopic rod 25. The electric drive roller abuts against the profile 13 to drive the profile 13 to move, thereby adjusting the position of the laser cutter 12 to cut the profile 13.

[0049] Among them, the six supporting components are evenly distributed on both sides with the laser cutter 12 as the center. Their function is to ensure that when the profile 13 is cut into two segments by the laser, any segment of the profile 13 can be clamped and limited by multiple points, thereby ensuring the stability of the profile 13 after the segment is cut.

[0050] Wherein: the carrier plate 29 is located on the path of the profile 13 being rotated downward by the support plate 22.

[0051] Among them: Since the four pressure plates 26 on a single support plate 22 are arranged in pairs and staggered, that is, there is a height difference between the two sets of pressure plates 26, the function of the leveling rod 39 is to level the height difference between the staggered pressure plates 26, so that the four electric push rods 31 are initially on the same plane.

[0052] Among them, the guide plate 36 is set to L-shape.

[0053] Among them, the chute 37 is inclined on the guide plate 36.

[0054] In the initial state, that is, before the laser cutting operation is performed on the profile 13, the structural states within the bracket assembly are as follows:

[0055] The rotating plate 24 flips on the linear guide rail 21 to a vertically upward state, the telescopic shaft of the telescopic rod 25 is fully retracted, the four pressure plates 26 on the same support plate 22 are far apart from each other to the maximum distance, that is, to form the largest rectangular passage. The profile 13 has not yet been placed in the rectangular passage, the tension spring 211 has not yet produced elastic deformation, the carrier plate 29 is in the highest position on the base 27. Since the four pressure plates 26 on the same support plate 22 are far apart from each other at this time, the four carrier frames 32 are also far apart from each other. The two clamping plates 34 on the carrier frame 32 are located at both ends of the guide groove 33, that is, the distance between the two clamping plates 34 is the largest at this time. The two sliding shafts 38 on the carrier frame 32 are respectively located at the far ends of the two sliding grooves 37. The telescopic shaft end of the electric push rod 31 is fully retracted.

[0056] In the working state, that is, when laser cutting is required on profile 13, the support assembly operates as follows:

[0057] The user inserts the profile 13 completely into the rectangular passage formed by the pressure plates 26 on the multiple support plates 22. At the same time, the user drives the telescopic shaft of the telescopic rod 25 to extend, causing the four pressure plates 26 on the single rotating plate 24 to move inward. As the pressure plates 26 move, all the pressure plates 26 press against the outer wall of the profile 13 through the electric drive rollers on them, thereby limiting the profile 13 on the operating table 11. At this time, the profile 13 can be pushed horizontally by the operation of the electric drive rollers to adjust the position of the profile 13 on the operating table 11.

[0058] At this time, the user can use the laser cutter 12 to perform laser cutting on the profile 13. The laser cutter 12 performs laser cutting operations on the profile 13, such as cutting holes, cutting lines, or completely cutting. During this process, the user can drive the rotating plate 24 to rotate, so that the rotating plate 24 drives the profile 13 to rotate. In conjunction with the operation of the electric drive roller of the pressure plate 26, the profile 13 can adjust its position and angle in real time according to the laser cutting requirements when being laser cut.

[0059] If the profile 13 is completely cut by the laser cutter 12, thus forming two independent profiles 13, the laser cutter 12 needs to perform laser cutting on the two profiles 13 respectively. At this time, each of the two profiles 13 is supported and limited by three support components, and all of them are multi-point limiting, which can effectively prevent the processing posture of the profile 13 from getting out of control.

[0060] It should be noted that if the profile 13 needs to be cut into multiple segments due to processing requirements, and the multiple segments are cut separately, the six support components can each limit one segment of the profile 13. By relying on the cooperation of the linear guide rail 21 and the rotating plate 23, as well as the cooperation of the electric drive rollers on each support component, the profile 13 can be switched and moved on multiple support components, ensuring that each segment of the profile 13 can be moved to the position of the laser cutter 12 for laser cutting processing.

[0061] If the laser cutting of a certain section of profile 13 is completed, it needs to be unloaded. At this time, the user can operate the support component that clamps and limits the corresponding section, so that the support component moves the profile 13 to the position of the base 27. Then, the rotating plate 23 drives the support plate 22 to rotate, so that the support plate 22 drives the clamped profile 13 to rotate downward. During the rotation of the support plate 22, the support plate 22 is located on the side of the base 27 without interfering, while the profile 13 is pressed against the carrier plate 29 as it rotates. Since the carrier plate 29 is at its highest position at this time, the profile 13 with a smaller cross-sectional size can be placed directly on the carrier plate 29, while the profile 13 with a larger cross-sectional size will press against the carrier plate 29 as the support plate 22 rotates, applying downward pressure to the carrier plate 29, causing the guide rod 28 and the slide plate 210 to slide downward, and the tension spring 211 to undergo elastic deformation. This design allows for the adaptation of profiles 13 with different cross-sectional dimensions, enabling profiles 13 with different cross-sectional dimensions to be flipped downwards along with the support plate 22 and placed on the carrier plate 29.

[0062] After placing the profile 13, the user can retract the four telescopic rods 25 of the support component, causing the pressure plates 26 to move away from each other and no longer clamp the profile 13. Simultaneously, the linear guide rail 21 and rotating plate 23 are activated, causing the support plate 22 to move away from the base 27 along the linear guide rail 21, thus allowing the profile 13 to be completely unloaded from the support plate 22. At this point, the laser-cut profile 13 is placed on the carrier plate 29. The entire unloading process is smooth, unlike existing methods such as direct discharge or ramp discharge. The entire unloading process is controllable by the support component, preventing damage to the profile 13 due to hard impacts during unloading.

[0063] After unloading, the user can operate the support plate 22 to flip upwards and resume laser cutting of the remaining profile sections 13. It should be noted that the above unloading process does not occupy the laser cutting time of the remaining profile sections 13. During unloading, the remaining support components can maintain the laser cutting work of the remaining profile sections 13, and unloading and laser cutting can be carried out in parallel.

[0064] It should be noted that in the above unloading operation, the number of supporting components involved in unloading is determined according to the number of components previously used to support and limit the profile 13. Preferably, two supporting components clamp the two ends of the profile 13 respectively for rotation and unloading.

[0065] As laser cutting progresses, if the preset processing parameters for laser cutting of profile 13 require a thin-edge cutting condition, specifically: a section of profile 13 is laser-cut into a shorter segment, and laser cutting is still needed on the side near the end. However, the portion near the end does not meet the limiting width requirement of the support component; that is, the required limiting length is greater than the remaining length of profile 13. In this case, the support component cannot support and limit the profile 13, leaving it suspended at one end. If this portion of profile 13 needs to be completely laser-cut, the cut portion will fall directly downwards, posing a risk of damage from a hard impact. Therefore, the user must operate the clamping component, as follows:

[0066] At this time, the end of the profile 13 that does not need to be processed is limited by the support component, while the clamping component on the support component near the laser processing point moves. According to the shape of the laser-cut part near the processing side, the four electric push rods 31 are driven to move. Specifically, since the profile 13 needs to be made into a special-shaped metal component, the end formed by laser cutting has a concave and convex cross section. The electric push rods 31 need to extend and retract according to the concave and convex cross section to ensure that the two clamping plates 34 on each electric push rod 31 can be clamped in the effective position on the inner and outer walls of the profile 13 respectively.

[0067] It should be noted that in the prior art, profile 13 has hollow characteristics, that is, it has inner and outer walls.

[0068] At this time, the telescopic shaft of the electric push rod 31 extends, pushing the clamping plate 34 to move towards the profile 13. During this process, the electric push rod 35 operates, and the telescopic shaft of the electric push rod 35 extends, pushing the guide plate 36 to slide inside the frame 32. As the guide plate 36 moves, the guide plate 36 drives the two sliding grooves 37 to slide on the two sliding shafts 38. Specifically, the two sliding shafts 38 move closer to each other under the guidance of the corresponding sliding grooves 37, so that the two clamping plates 34 slide closer to each other in the guide grooves 33, that is, the distance between the two clamping plates 34 is reduced.

[0069] At this time, as the telescopic shaft of the electric push rod 31 extends, the two clamping plates 34 move closer to the profile 13. The two clamping plates 34 move to the inner and outer sides of the profile 13 respectively. As the two clamping plates 34 approach each other, they clamp the inner and outer sides of the profile 13 respectively. When all four electric push rods 31 extend to the concave and convex positions on the corresponding profile 13 cross-section, there are two clamping plates 34 on each of the four sides of the profile 13 to clamp the inner and outer walls. That is, the four sides of the profile 13 are clamped and limited.

[0070] It should be noted that: by extending and retracting the electric push rod 31, it can adapt to profiles 13 with irregular cross sections, and effectively clamp and limit the profiles 13 with irregular cross sections on all four sides. By moving the clamping plate 34, it can adapt to profiles 13 with different thicknesses.

[0071] At this point, the profile 13 is positioned. The user can use the laser cutter 12 to laser cut the profile 13. After the profile 13 is cut, the completely cut profile 13 is positioned by the clamping plate 34. The user can place the profile 13 on the carrier plate 29 by rotating the support plate 22.

[0072] It should be noted that during the laser cutting and clamping process of the profile 13, the end of the profile 13 closest to the laser cutting position is always limited by the clamping plate 34, forming an effective constraint, providing effective support for the short end of the profile 13 on the cutting side, and preventing it from losing its posture and falling and being damaged.

[0073] In summary, the following beneficial effects can be achieved through the design of the support components:

[0074] By combining the annular multi-point adjustable pressure plate 26 with multiple support components, a stable clamping of the profile 13 with any complex cross-section over a long span is achieved. The profile 13 will not shift, twist, or vibrate during the cutting process. At the same time, with the electric drive rollers on the pressure plate 26 and the self-rotation function of the rotating plate 24, the position and angle of the profile 13 can be adjusted in real time to ensure that the laser cutter 12 is always aligned with the optimal processing trajectory, thereby obtaining high-precision cuts and dimensions.

[0075] The design of clamping the inner and outer walls of the profile 13 simultaneously by clamping the clamping components ensures that even very short sections of the profile 13 or small pieces of workpieces cut off can be firmly fixed, avoiding edge chipping, surface scratches or workpiece scrap caused by falling.

[0076] By using the flexible support structure of the carrier plate 29 and the tension spring 211, combined with the rotating material feeding action of the support component, the unloading process of the profile 13 is placed rather than thrown, avoiding the hard collision in the traditional material feeding method, effectively maintaining the smoothness of the processed surface and the overall appearance of the profile 13, and reducing subsequent finishing processes.

[0077] Example 2:

[0078] A laser cutting process for irregularly shaped metal components includes the following steps:

[0079] Step 1: Insert the profile 13 into the rectangular passage formed by multiple pressure plates 26, drive the telescopic rod 25 to move the pressure plates 26 inward until the electric drive roller presses against the outer wall of the profile 13, thus completing the limiting and alignment.

[0080] Step 2: Start the laser cutter 12 to cut. During the process, drive the rotating plate 24 to rotate the profile 13 and move it in conjunction with the electric drive roller to adjust the position and angle of the profile 13 in real time to ensure the cutting trajectory is accurate.

[0081] Step 3: After the profile 13 is completely cut into multiple segments, each segment is limited by the corresponding support components. Relying on the linear guide 21 and the electric drive roller, each segment is moved to the laser cutter 12 for processing in sequence.

[0082] Step 4: When the remaining profile 13 is not long enough, activate the clamping components: electric push rod 1 31 extends, electric push rod 2 35 drives the two clamping plates 34 to come together, clamping the inner and outer walls of the profile 13 respectively, to prevent it from falling and being damaged during cutting.

[0083] Further, in step five: the processed profile 13 is rotated downward by the support plate 22, pressing the carrier plate 29 and compressing the tension spring 211 to flexibly support it; then the telescopic rod 25 retracts and releases the pressure plate 26, the support plate 22 moves away, and the profile 13 remains on the carrier plate 29 to complete the unloading.

[0084] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way.
