Description

Technical Field

[0001] This application relates to the field of sheet metal production and processing technology, and in particular to a sheet metal cutting device. Background Technology

[0002] Sheet metal processing is a crucial part of modern manufacturing, widely used in the automotive, aerospace, and electronic equipment industries. With the advancement of industrial automation, traditional sheet metal cutting techniques are gradually evolving towards higher precision and efficiency. Currently, laser cutting technology, due to its non-contact processing, high precision, and high efficiency, has become one of the mainstream sheet metal cutting technologies. However, existing laser cutting equipment still has certain limitations in terms of cutting angle adjustment, making it difficult to meet the processing needs of complex-shaped sheet metal parts.

[0003] In existing technologies, sheet metal cutting mainly employs three types of laser cutting machines: First, fixed laser cutting machines, which use a fixed laser head position and rely on moving the workpiece or laser head to perform linear cutting. These machines have a simple structure but cannot achieve multi-angle cutting. Second, robotic arm laser cutting machines, which use a robotic arm to drive the laser cylinder to perform multi-angle cutting. These machines offer high flexibility but are expensive and require a large footprint. Third, track-type laser cutting machines, which use a linear track to move the laser head. These machines are suitable for large workpieces but have limited ability to adjust the cutting angle.

[0004] Regarding the aforementioned existing technologies, fixed laser cutting machines cannot meet the needs of multi-angle cutting; robotic arm laser cutting machines are costly and complex to maintain; and although track-type laser cutting machines can cover a large processing range, their angle adjustment capability is insufficient and they are difficult to adapt to the processing needs of complex sheet metal parts. Utility Model Content

[0005] In view of the above-mentioned prior art, in order to solve the problem that the cutting device cannot realize multi-angle adjustment of the laser cutting head and is difficult to meet the cutting needs of complex sheet metal parts, this application provides a sheet metal cutting device.

[0006] This application provides a sheet metal cutting device, which adopts the following technical solution: A sheet metal cutting device includes an internally suspended support frame and a moving mechanism for moving the support frame. The support frame is mounted on the moving mechanism, and the support frame is provided with a cutting mechanism for cutting sheet metal parts. The cutting mechanism includes an upper annular track, a lower annular track, an equipment frame, a drive component, a drive wheel, an upper moving component, a lower moving component, and a laser cutting head. The upper and lower annular tracks are fixed to the top and bottom of the support frame, respectively. The drive wheel is disposed on the upper and lower annular tracks. The equipment frame is disposed between the upper and lower annular tracks. The drive component is fixed on top and connected to the drive wheel. The upper and lower moving components are fixed above and below the equipment frame, respectively, and are disposed opposite to each other. The laser cutting head is disposed on the upper and lower moving components, allowing the upper and lower moving components to adjust the cutting angle of the laser cutting head.

[0007] By adopting the above technical solution, the support frame can be moved as a whole by the moving mechanism, and the relative position of the cutting mechanism and the sheet metal parts can be adjusted to adapt to the processing range of sheet metal parts of different sizes. In the cutting mechanism, the driving component drives the driving wheel to roll along the upper and lower circular tracks, and drives the equipment frame to make a 360° circular motion around the circular track, so as to realize the circular trajectory movement of the laser cutting head. At the same time, the upper moving component and the lower moving component are set opposite to each other and connected to the laser cutting head respectively. Through the coordinated action of the two, the spray angle of the laser cutting head can be adjusted to meet the cutting needs of different positions (plane, side, and inclined) of the sheet metal parts.

[0008] Preferably, the upper moving component includes a support plate, a first motor, a first lead screw, a first moving block, a first connecting member, and a first guide rail for guiding the first moving block. The top of the support plate is fixedly connected to the top of the inner side of the equipment frame. The first motor is fixed on the support plate. The output end of the first motor is coaxially connected to one end of the first lead screw. The other end of the first lead screw is rotatably connected to the support plate. The first moving block is threadedly connected to the first lead screw via threaded balls. The bottom of the first moving block is slidably connected to the first guide rail. The top of the first guide rail is fixedly connected to the bottom of the support plate. The first connecting member is fixed to the bottom of the first moving block and is rotatably connected to the laser cutting head via a rotating shaft.

[0009] By adopting the above technical solution, the rotational motion of the first motor is converted into the linear motion of the first moving block through the rotation of the first lead screw driven by the first motor and the threaded ball bearing engaged with the first moving block. This allows the first moving block to move and adjust the upper part of the laser cutting head via the first connecting member. At the same time, the first guide rail cooperates with the first moving block to provide guidance and constraint for the first moving block, preventing deviation and shaking during movement, ensuring the straightness of the laser cutting head's movement trajectory, and improving the flatness of the cutting edge. Meanwhile, the first connecting member is rotatably connected to the laser cutting head via a rotating shaft, which allows the laser cutting head to swing on the basis of horizontal movement. In conjunction with the lower moving member, the angle adjustment of the laser cutting head is further expanded, enabling it to perform multi-angle cutting.

[0010] Preferably, the lower moving component includes a U-shaped connecting plate, a second motor, a second lead screw, a second moving block, a second connecting member, and a second guide rail for guiding the second moving block. The bottom of the U-shaped connecting plate is fixedly connected to the bottom of the inner side of the equipment frame. The second motor is fixed on the U-shaped connecting plate. The output end of the second motor is coaxially connected to one end of the second lead screw. The other end of the second lead screw is rotatably connected to the end of the U-shaped connecting plate away from the second motor. The second moving block is threadedly connected to the second lead screw via threaded balls. The bottom of the second moving block is slidably connected to the second guide rail. The bottom of the second guide rail is fixedly connected to the top of the U-shaped connecting plate. The top of the second moving block is fixedly connected to the bottom of the second connecting member. The second connecting member is rotatably connected to the laser cutting head via a rotating shaft.

[0011] By adopting the above technical solution, the U-shaped connecting plate provides a stable installation space for the second lead screw and the second moving block, enabling the second motor to drive the second lead screw to rotate. The second lead screw drives the second moving block to move linearly, allowing the second moving block to move and adjust the lower part of the laser cutting head. The second guide rail cooperates with the second moving block to provide guidance and constraint for the second moving block, preventing deviation and shaking during movement, ensuring the straightness of the laser cutting head's movement trajectory, and improving the flatness of the cutting surface. At the same time, the second connecting piece is rotatably connected to the laser cutting head through a rotating shaft, which allows the laser cutting head to swing on the basis of horizontal movement. With the moving piece, the angle adjustment of the laser cutting head is further expanded, enabling it to perform multi-angle cutting.

[0012] Preferably, the top and bottom of the equipment frame are provided with multiple sets of guide wheels for assisting the movement of the drive wheels, and the guide wheels are arranged on the upper annular track and the lower annular track.

[0013] By adopting the above technical solution and using multiple sets of guide wheels, the movement trajectory of the drive wheels can be made more regular, reducing the swaying and shaking when the equipment frame moves. This makes the equipment frame move more stably along the upper and lower circular tracks, avoiding the laser cutting welding head from shifting. It can significantly improve the flatness and dimensional accuracy of the cutting edge, reduce the processing error of sheet metal parts, and improve the finished product qualification rate.

[0014] Preferably, the support frame includes a top plate, a bottom plate, side plates, and support columns. The bottom plate and the top plate are fixedly connected to the side plates on the side plates. The side plates are connected to the moving mechanism. The top and bottom of the support columns are fixedly connected to the top plate and the bottom plate, respectively.

[0015] By adopting the above technical solution, the top plate and bottom plate form a closed frame structure through the side plates and support columns. The multi-point fixing makes the overall rigidity higher, which can effectively resist the vibration and load during the cutting process, avoid the deformation of the support frame, and ensure the installation accuracy of the cutting mechanism. At the same time, the internal suspended hollow structure provides sufficient space for the installation of the upper and lower ring tracks and equipment frame, does not obstruct the working path of the laser cutting head, facilitates the handling of sheet metal parts, and adapts to the spatial requirements of ring cutting.

[0016] Preferably, a reinforcing plate is provided at the connection between the side plate and the top plate and the bottom plate, and the reinforcing plate is in the shape of a right trapezoid.

[0017] By adopting the above technical solution, the two right-angled sides of the right trapezoid can be tightly attached and fixed to the side plate and the top / bottom plate respectively to form a triangular support structure, which greatly improves the shear and bending resistance of the connection and avoids loosening of the connection due to long-term stress or vibration. At the same time, the hypotenuse of the trapezoidal structure can disperse the concentrated load at the connection and transmit the force between the side plate and the top / bottom plate to the reinforcing plate itself and the surrounding structure, reducing local stress concentration and reducing the risk of deformation and cracking at the connection.

[0018] Preferably, the top plate and the bottom plate are provided with circular grooves, and the upper annular track and the lower annular track are respectively arranged at the positions of the annular grooves on the top plate and the bottom plate.

[0019] By adopting the above technical solution, the outline of the circular groove matches the annular track, which can be directly used as the reference surface for track installation, quickly achieving coaxial alignment of the upper and lower annular tracks, reducing positioning errors during assembly, and improving installation efficiency.

[0020] Preferably, the moving mechanism includes a frame, a servo motor, a screw, and a moving plate. The servo motor is fixed to the inner wall of the frame, and the output end of the servo motor is coaxially connected to one end of the screw. The other end of the screw is rotatably connected to the inner wall of the frame through a bearing. The moving plate is threaded onto the screw, and a moving groove for guiding the movement of the moving plate is provided at the bottom of the frame. The moving plate is fixedly connected to the support frame.

[0021] By adopting the above technical solution, the servo motor has high control precision. In conjunction with the screw thread transmission, it can accurately convert the rotational motion into the linear motion of the moving plate. It can precisely control the moving distance of the support frame to meet the position adjustment requirements of high-precision cutting. At the same time, the moving slot provides a dedicated guide path for the moving plate, restricts the offset direction of the moving plate, avoids shaking or jamming during the movement, ensures that the support frame drives the cutting mechanism to move smoothly, and ensures the regularity of the cutting trajectory.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The moving mechanism, through the precise transmission of servo motors and screws, drives the support frame to move linearly as a whole. It can flexibly adjust the relative position of the cutting mechanism and the sheet metal parts, easily adapting to the processing range of sheet metal parts of different sizes. There is no need to frequently change tooling or adjust the workpiece placement. The cutting mechanism adopts an upper and lower circular track design, and the driving component drives the equipment frame to move 360° in a circular motion, realizing the circular trajectory coverage of the laser cutting head. With the coordinated action of the upper and lower moving components, it can achieve linear adjustment of the upper and lower ends of the laser cutting head through the lead screw transmission, and can also achieve multi-angle swing through the rotating shaft connection. It can accurately meet the cutting needs of different positions of sheet metal parts such as planes, sides, and bevels, greatly expanding the processing scenarios. 2. This utility model uses dedicated guide rails (first guide rail and second guide rail) on both the upper and lower moving parts to slide with the moving block, effectively constraining the movement trajectory, avoiding deviation and shaking, ensuring the straightness of the laser cutting head movement, and significantly improving the flatness of the cutting edge.

[0023] 3. This utility model adds multiple sets of guide wheels to the top and bottom of the equipment frame to assist the drive wheels in moving along the circular track, reducing the movement and shaking of the equipment frame, ensuring the regularity of the circular trajectory movement, avoiding laser cutting head deviation, reducing processing errors, and improving dimensional accuracy.

[0024] 4. This utility model combines the high-precision control of the servo motor with the stability of the threaded transmission, enabling precise positioning for both the overall movement of the support frame and the angle adjustment of the laser cutting head, reducing processing deviations and effectively improving the finished product qualification rate.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail.

[0028] This application discloses a sheet metal cutting device.

[0029] Reference Figures 1 to 5 A sheet metal cutting device includes a support frame 100, a moving mechanism 200, and a cutting mechanism 300. The support frame 100 is internally suspended and is mounted on the moving mechanism 200, allowing the moving mechanism 200 to move and adjust the support frame 100. The cutting mechanism 300 is mounted on the support frame 100 and moves with the support frame 100. The position of the cutting mechanism 300 is adjusted and adapted by the moving mechanism 200 according to the size of the sheet metal part and the cutting area. The support frame 100 includes a side plate 130, a bottom plate 120, a top plate 110, and a support column 140. One end of the side plate 130 is detachably connected to the moving mechanism 200 by bolts and nuts. The ends of the bottom plate 120 and the top plate 110 near the side plate 130 are fixedly connected to the side plate 130 by bolts and nuts. The top and bottom ends of the support column 140 are fixedly connected to the ends of the top plate 110 and the bottom plate 120 away from the side plate 130, respectively. The support column 140 is located between the bottom plate 120 and the top plate 110, forming a suspended space between the side plate 130, the top plate 110, the bottom plate 120, and the support column 140. The cutting mechanism 300 is installed in the suspended space. The cutting mechanism 300 includes an upper annular track 310, a lower annular track 320, an equipment frame 330, a drive component 340, a drive wheel 350, an upper moving component 360, a lower moving component 370, and a laser cutting head 380. The top of the upper annular track 310 is fixedly connected to the bottom of the top plate 110 of the support frame 100 by screws. The bottom of the lower annular track 320 is fixedly connected to the top of the bottom plate 120 of the support frame 100 by bolts. The equipment frame 330 is movably connected between the upper annular track 310 and the lower annular track 320. A pneumatic component is fixed to the inner wall of the equipment frame 330. The output end of the drive component 340 is coaxially connected to the drive wheel 350. The upper annular track 310 and the lower annular track 320 are connected to each other, so that the drive wheel 350 is driven by the drive component 340 to move on the upper annular track 310 and the lower annular track 320. The top of the upper moving component 360 is fixed to the top of the inner side of the equipment frame 330 by bolts and nuts, and the lower moving component 370 is fixed to the bottom of the inner side of the equipment frame 330 by bolts and nuts, so that the upper moving component 360 and the lower moving component 370 are set opposite to each other. The laser cutting equipment is rotatably connected with the upper moving component 360 and the lower moving component 370, so that the upper moving component 360 and the lower moving component 370 cooperate to adjust the angle of the laser cutting head 380, thereby adjusting the cutting angle to adapt to the cutting of inclined planes, planes and sides.

[0030] Specifically, the sheet metal part is placed on the cutting worktable, and the moving mechanism 200 is installed on the worktable. Activating the moving mechanism 200 moves the support frame 100 and the cutting mechanism 300 to the area of ​​the sheet metal part to be cut. Then, the drive unit 340 on the equipment frame 330 is activated. The drive unit 340 uses a servo motor 220, which drives the drive wheel 350 via a connecting shaft to move on the upper annular track 310 and the lower annular track 320. This causes the drive wheel 350 to rotate and adjust the equipment frame 330, thereby adjusting the cutting position of the laser cutting head 380. Then, by working with the upper moving part 360 and the lower moving part 370, the cutting angle of the laser cutting head 380 is adjusted to make it suitable for cutting planes, bevels, and sides. During cutting, the driving part 340 drives the driving wheel 350 to roll along the upper and lower annular tracks 320, which drives the equipment frame 330 to make a 360° circular motion around the annular tracks, realizing the circular trajectory movement of the laser cutting head 380. At the same time, the upper moving part 360 and the lower moving part 370 are set relative to each other and connected to the laser cutting head 380. Through the coordinated action of the two, the jet angle of the laser cutting head 380 is adjusted to meet the cutting needs of different positions of the sheet metal parts, including planes, sides, and bevels.

[0031] refer to Figure 2The support frame 100 has circular grooves 160 on both the bottom plate 120 and the top plate 110. The upper annular track 310 and the lower annular track 320 are fixed at the circular grooves 160 of the top plate 110 and the bottom plate 120, respectively, so that there is room for installation and the laser cutting head 380 can be installed and adjusted to avoid motion interference.

[0032] A reinforcing plate 150 is fixedly connected to the connection between the side plate 130 and the top plate 110 and the bottom plate 120. The reinforcing plate 150 is in the shape of a right trapezoid, which strengthens the connection between the top plate 110 and the side plate 130, reduces stress concentration, and enhances the load-bearing capacity of the support frame 100.

[0033] The top plate 110 and the bottom plate 120 are provided with circular grooves 160. The upper annular track 310 and the lower annular track 320 are respectively set at the positions of the annular grooves on the top plate 110 and the bottom plate 120. The outline of the circular groove 160 matches the annular track, which can be directly used as the reference surface for track installation. The coaxial alignment of the lower annular track 320 can be quickly achieved, reducing positioning errors during assembly and improving installation efficiency.

[0034] refer to Figure 3 and Figure 4 The upper moving part 360 includes a support plate 361, a first motor 362, a first lead screw 363, a first moving block 364, a first connecting piece 365, and a first guide rail 366. The support plate 361 is inverted U-shaped, and its top is bolted to the top of the inner side of the equipment frame 330. The first lead screw 363 is rotatably connected to the bottom of the support plate 361. The first motor 362 is fixed to one end of the support plate 361, and its output end is coaxially connected to the first lead screw 363 via a coupling. The first moving block 364 is threadedly connected to the first lead screw 363. The first guide rail 366 is fixed to the bottom of the support plate 361. The first guide rail 366 limits and guides the first moving block 364, so that the first motor 362 drives the first lead screw 363 to rotate. The first lead screw 363 drives the first moving block 364 to move linearly on the first guide rail 366. The first connecting piece 365 is a connecting plate. The top of the first connecting piece 365 is fixedly connected to the bottom of the first moving block 364. The first connecting piece 365 is rotatably connected to the laser cutting head 380 through the connecting shaft, so that the laser cutting head 380 can be rotated and adjusted with the cooperation of the first moving piece and the second moving piece.

[0035] Specifically, the first motor 362 drives the first lead screw 363 to rotate, and then the threaded ball engages with the first moving block 364, converting the rotational motion of the first motor 362 into the linear motion of the first moving block 364. This allows the first moving block 364 to move and adjust the laser cutting head 380 via the first connecting member 365. At the same time, the first guide rail 366 cooperates with the first moving block 364 to provide guidance and constraint for the first moving block 364, preventing deviation and shaking during movement, ensuring the straightness of the laser cutting head 380's movement trajectory, and improving the flatness of the cut. Meanwhile, the first connecting member 365 is rotatably connected to the laser cutting head 380 via a rotating shaft, enabling the laser cutting head 380 to swing on top of horizontal movement. In conjunction with the lower moving member 370, this further expands the angle adjustment of the laser cutting head 380, allowing it to perform multi-angle cuts.

[0036] refer to Figure 4 and Figure 5 The top and bottom of the equipment frame 330 are equipped with multiple sets of guide wheels 390 to assist the movement of the drive wheel 350. The guide wheels 390 are set on the upper annular track 310 and the lower annular track 320. The multiple sets of guide wheels 390 assist the drive wheel 350, which makes the movement trajectory of the drive wheel 350 more regular, reduces the swaying and shaking when the equipment frame 330 moves, and makes the movement of the equipment frame 330 along the upper annular track 310 and the linear annular track more stable. It avoids the laser cutting welding head from moving and deviating, which can significantly improve the flatness and dimensional accuracy of the cutting edge, reduce the processing error of sheet metal parts, and improve the finished product qualification rate.

[0037] refer to Figure 5 and Figure 6 The lower moving part 370 includes a U-shaped connecting plate 371, a second motor 372, a second lead screw 373, a second moving block 374, a second connecting part 375, and a second guide rail 376. The bottom of the U-shaped connecting plate 371 is fixedly connected to the bottom of the inner side of the equipment frame 330 via bolts and nuts. The second lead screw 373 is rotatably connected to the U-shaped connecting plate 371. The second motor 372 is fixed to the U-shaped connecting plate 371 via a motor mount, and the output end of the second motor 372 is coaxially fixedly connected to the second lead screw 373 via a coupling. The second moving block 374 is threadedly connected to... The second lead screw 373 is mounted on the second moving block 374, which is slidably connected to the second guide rail 376. The bottom of the second guide rail 376 is fixedly connected to the top of the U-shaped connecting plate 371, so that the second guide rail 376 guides the movement of the second moving block 374, reduces the offset of the movement of the second moving block 374, and makes its movement more stable. The second connecting piece 375 is fixed to the top of the second moving block 374. The second connecting piece 375 has the same structure as the first connecting piece 365, and the second connecting piece 375 is rotatably connected to the laser cutting head 380 through a rotating shaft, so that it can be rotated and adjusted.

[0038] The above-mentioned design of the U-shaped connecting plate provides a more comprehensive load-bearing space. The bottom is firmly fixed to the equipment frame 330, and the top provides a stable mounting base for the second guide rail 376 and the moving block, distributing the weight of the laser cutting head 380 and reducing the impact of vibration. It also adopts the transmission method of "second motor 372 + second lead screw 373 + threaded ball", which has high transmission accuracy and small gap. It can realize the linear movement of the laser cutting head 380 synchronously with the upper moving part 360, ensuring consistent up and down adjustment and improving positioning accuracy. In addition, the second guide rail 376 and the second moving block 374 slide together to provide precise guidance for the linear movement of the moving block, avoiding left and right swaying or deviation during the movement, and ensuring that the movement trajectory of the laser cutting head 380 is regular.

[0039] refer to Figure 7 The moving mechanism 200 includes a frame 210, a servo motor 220, a screw 230, and a moving plate 240. The frame 210 is formed by splicing and fixing multiple sets of panels to create an installation space inside. The servo motor 220 is fixedly mounted on the inner wall of the frame 210 via a motor support. One end of the screw 230 is coaxially fixedly connected to the output end of the servo motor 220, and the other end of the screw 230 is rotatably connected to the inner wall of the frame 210 via a bearing. The moving plate 240 is screwed onto the screw 230. A moving groove 250 is provided at the bottom of the frame 210 to guide and limit the moving plate 240, allowing it to move linearly as the screw 230 rotates, thereby driving the support frame 100 to move and adjust. The implementation principle of this application embodiment is as follows: In implementation, the moving mechanism 200, the support frame 100, and the cutting mechanism 300 are installed as a whole on the sheet metal cutting workbench. The sheet metal part is placed on the workbench, and the servo motor 220 on the moving mechanism 200 is started. The servo motor 220 drives the screw 230 to rotate, and the screw 230 drives the moving plate 240 to move within the moving groove 250. The moving plate 240 drives the support frame 100, which is composed of the side plate 130, the top plate 110, the bottom plate 120, and the support column 140. The support frame 100 is moved, causing the cutting mechanism 300 to move to the area of ​​the sheet metal part that needs to be cut. Then, the first motor 362 and the second motor 372 on the upper moving part 360 and the lower moving part 370 are activated. The first motor 362 drives the first lead screw 363 to rotate, and the second motor 372 drives the second lead screw 373 to rotate. The first lead screw 363 and the second lead screw 373 respectively drive the first moving block 364 and the second moving block 374 along the first guide rail 366 and the second guide rail 377. The first moving block 364 and the second moving block 374 respectively drive the first connecting piece 365 and the second connecting piece 375 to move. The first connecting piece 365 and the second connecting piece 375 drive the laser cutting head 380 to move and adjust. After adjustment, the upper moving piece 360 ​​can work while the lower moving piece 370 does not work, so that the cutting angle of the laser cutting head 380 can be adjusted to be in a vertical plane, an inclined plane, or a side angle. This allows for inclined, flat, and side cutting of sheet metal parts. After adjustment, the drive piece 340 on the equipment frame 330 is activated. The drive piece 340 drives the drive wheel 350 to move on the upper annular track 310 and the lower annular track 320, so that the laser cutting head 380 starts working and performs annular cutting. This achieves both linear adjustment of the upper and lower ends of the laser cutting head 380 through screw drive and multi-angle swing through the rotating shaft connection. It can accurately meet the cutting needs of sheet metal parts in different positions such as flat, side, and inclined planes, greatly expanding the processing scenarios.

[0040] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
