Description

Technical Field

[0001] This invention relates to the field of metal sheet cutting technology, specifically to a sheet processing and cutting device. Background Technology

[0002] The core objective of metal sheet cutting is to efficiently and accurately divide standard-sized raw material sheets into the required shapes and sizes according to digital design drawings. Laser cutting is one of the cutting methods. The working principle of laser cutting is to focus a high-power laser beam on the surface of the metal sheet, causing it to quickly reach its melting or boiling point. At the same time, an auxiliary gas coaxial with the beam blows away the molten material, forming a kerf. Therefore, it can adapt to the cutting of complex shapes. However, when cutting the outer contour, the CAM software will set several "breakpoints" on the path. At these points, the laser does not completely cut through, leaving very small (usually 0.2mm~0.5mm) connection points. These micro-connections are sufficient to firmly fix the parts to the metal sheet frame, preventing them from shifting or falling during the cutting process, thus ensuring the cutting quality of the metal sheet. After the cutting is completed, the parts can be easily broken off from the micro-connections by manual tapping, robotic gripping, special vibration devices, or sorting equipment to achieve the removal of the parts.

[0003] In the above process, the size of the sheet metal will change depending on the requirements. Therefore, the distance between the clamps needs to be adjusted during the clamping process to secure the sheet metal firmly. At the same time, the size of the conveying device also needs to be adjusted, because the conveying device needs to transport the cut sheet metal and also separate the workpiece and waste. If a simple crawler conveyor is used, it will not be able to separate the workpiece or waste. If other equipment is used for separation, it will not only increase the cost, but also be detrimental to continuous processing. It is necessary to coordinate the processing efficiency of the separation equipment and this device, which is time-consuming and labor-intensive.

[0004] A search revealed that Chinese patent application CN108501129B discloses a sheet metal cutting device. Although it can adjust the angle of the cutting tool according to the angle of the sheet metal to reduce cutting errors, it cannot solve the aforementioned problem. Summary of the Invention

[0008] As a further embodiment of the present invention: the cross-section of the rotating rod is mushroom-shaped, and the rotating rod is sleeved with the first clamping plate, the transmission bevel gear, the driven bevel gear and the first worm gear. The rotating rod is fitted and connected with the connecting rod, and the planetary bevel gear is rotatably sleeved with the first inner cavity.

[0009] As a further aspect of the present invention: the second conveyor belt and the lead screw are both rotatably sleeved with the first clamping plate, and the second conveyor belt is fitted into the groove.

[0010] As a further embodiment of the present invention: a pressure frame is fixedly connected to the end of the connecting rod, a first pressure wheel is hinged inside the pressure frame, a bearing frame is fixedly connected to the side wall of the second clamping plate, a second pressure wheel is hinged inside the bearing frame, and a second inner cavity is opened in the side wall of the bearing frame, a magnetic ring is fixedly connected to the end of the second pressure wheel, a coil is sleeved on the magnetic ring, two pressure frames are provided, a telescopic rod is fixedly connected between the two pressure frames, and a third inner cavity is opened in the side wall of the pressure frame.

[0011] As a further embodiment of the present invention: multiple first pressure rollers and multiple second pressure rollers are provided; the coil is fixedly connected to the side wall of the second inner cavity; the coil corresponds one-to-one with the second pressure roller; the ends of adjacent coils are connected; and the telescopic rod can extend and retract in multiple stages.

[0012] As a further embodiment of the present invention: a second worm gear is rotatably connected to the side wall of the third inner cavity, a second worm wheel is meshed with the outer surface of the second worm gear, a driving gear is fixedly connected to the bottom surface of the second worm wheel, a driven gear ring is meshed with the outer surface of the driving gear, a rotating sleeve is fixedly connected to the inner surface of the driven gear ring, a guide groove is formed on the inner surface of the rotating sleeve, a slider is slidably connected in the guide groove, a push rod is fixedly connected to the end of the slider, a guide rod is fitted on the central axis of the push rod, a fixing rod is fixedly connected to the top surface of the guide rod, and a return spring is fixedly connected between the fixing rod and the push rod.

[0013] As a further embodiment of the present invention: the guide groove is a single-turn spiral groove with the beginning and end connected; the cross-section of the guide rod is mushroom-shaped; the fixing rod is L-shaped and fixedly connected to the top surface of the pressure frame; the reset spring is sleeved on the guide rod; the top rod is sleeved on the rotating sleeve; the end of the second worm gear is fixedly connected to the central axis of the first pressure wheel; the driven gear ring is sleeved on the third inner cavity; and the driving gear is rotatably connected to the bottom surface of the third inner cavity.

[0014] Compared with the prior art, the beneficial effects of the present invention, using the above technical solution, are as follows: 1. This invention generates an induced magnetic field through a coil, which drives a magnetic ring to rotate. This rotation causes the second pressure roller on the magnetic ring to rotate, allowing the second pressure roller to work in conjunction with the first pressure roller to move the cut sheet material horizontally. During this translation, the sheet material comes into contact with the first pressure roller on the second worm gear. This causes the sheet material to drive the second worm gear to rotate via the first pressure roller, resulting in the rotation of the second worm wheel on the second worm gear. This, in turn, causes the driving gear on the second worm wheel to rotate, which in turn causes the rotating sleeve on the driven gear to rotate. Consequently, the guide groove on the rotating sleeve rotates clockwise, causing the sidewall of the guide groove to press down on the slider. The push rod on the slider is restricted by the guide rod and cannot... The slider rotates, causing it to fall under the pressure of the guide groove and stretch the return spring until it reaches the bottom of the guide groove. At this point, the guide groove no longer restricts the slider's upward movement, allowing the slider and push rod to return to their original positions under the spring's rebound. This process is repeated, allowing the push rod to rise and fall repeatedly. This allows the push rod to extend from the rotating sleeve and impact the cut sheet metal, causing the workpiece to detach from the sheet metal frame. This achieves the purpose of separating the workpiece from the waste material, eliminating the need for manual hammering, robotic gripping, dedicated vibration devices, or sorting equipment. This not only reduces costs but also facilitates continuous processing. It eliminates the need to coordinate the processing efficiency of the separation equipment with that of the device, saving time and effort.

[0015] 2. This invention uses a first clamping plate and a second clamping plate to push the plate, positioning it at a designated location on the worktable and initially restricting its movement. During this process, as the driven bevel gear rotates, the first worm gear on the driven bevel gear drives the first worm wheel to rotate, causing the lead screw on the first worm wheel to move the connecting rod. The connecting rod is slidably connected to the first and second clamping plates, preventing it from rotating. Therefore, the connecting rod descends under the drive of the lead screw, causing the pressure frame on the connecting rod to drive the first pressure roller to descend until the first pressure roller, in conjunction with the second pressure roller, clamps the end of the plate, achieving full fixation of the plate. The opposing movement of the second clamping plate causes the connecting rod to move in the opposite direction, causing the pressure frame and the bearing frame to move in opposite directions, changing the width of the conveying mechanism. Simultaneously, the descent of the pressure frame changes the height of the conveying mechanism, allowing the first and second pressure rollers to clamp the edge of the plate and simultaneously move the plate horizontally. Therefore, the adjustment of the clamp can be synchronized with the adjustment of the conveying device, eliminating the need for separate adjustments, saving time and effort. Furthermore, the cutting device can adapt to the cutting of various types of plates, expanding its applicability.

[0016] 3. When the first clamping plate and the second clamping plate fix the plate before the first pressure roller, the transmission bevel gear that indirectly drives the movement of the first clamping plate and the second clamping plate is fixed. As the rotating rod continues to rotate, the connecting rod still drives the planetary bevel gear to revolve. The connecting rod is rotatably connected to the planetary bevel gear, so that the planetary bevel gear rotates on its own axis and revolves at the same time when blocked by the transmission bevel gear, thus not affecting the rotation of the driven bevel gear, so that the first pressure roller can still descend. Conversely, when the first pressure roller fixes the plate before the first clamping plate and the second clamping plate, the first clamping plate and the second clamping plate can still further fix the plate. It can adapt to the fixing of plates of various sizes, thereby ensuring the quality of plate cutting. Attached Figure Description

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] Example 1, please refer to Figures 1-5 This invention provides a technical solution: a sheet metal processing and cutting device, including a laser cutting machine body 1, a worktable 2 slidably connected to the top surface of the laser cutting machine body 1, a groove 3 formed on the top surface of the worktable 2, a bidirectional screw 4 rotatably connected to the side wall of the groove 3, two bidirectional screws 4 are provided, a first conveyor belt 5 is fixedly connected between the two bidirectional screws 4, and a second clamping plate 7 is threaded to both ends of one bidirectional screw 4, and a first clamping plate 6 is threaded to both ends of the other bidirectional screw 4. A first inner cavity 10 is formed at the bottom end of the first clamping plate 6, a motor 8 is installed on the side wall of the worktable 2, and a rotating rod 9 is fixedly connected to the output end of the motor 8. One end of a connecting rod 11 is surface-fitted and connected, and the other end of the connecting rod 11 is rotatably connected to a planetary bevel gear 12. The outer surface of the planetary bevel gear 12 is meshed with a drive bevel gear 13 and a driven bevel gear 14. One end of a second conveyor belt 15 is fixedly connected to the end face of the drive bevel gear 13. The other end of the second conveyor belt 15 is sleeved with a bidirectional screw 4, and a groove 16 is opened on the external thread of the bidirectional screw 4. A first worm 17 is fixedly connected to the end face of the driven bevel gear 14. A first worm wheel 18 is meshed and connected to the outer surface of the first worm 17. A lead screw 19 is fixedly connected to the central axis of the first worm wheel 18, and a connecting rod 20 is threadedly connected to the outer surface of the lead screw 19.

[0021] Please see Figure 3 and Figure 4 Two of each of the first clamping plate 6, the second clamping plate 7, and the connecting rod 20 are provided. The connecting rod 20 is slidably connected to the first clamping plate 6 and the second clamping plate 7. The first clamping plate 6 and the second clamping plate 7 are slidably connected to the slide groove 3. The rotating rod 9 is sleeved on the worktable 2, and the rotating rod 9 is rotatably connected to the side wall of the slide groove 3.

[0022] Please see Figure 4 The cross-section of the rotating rod 9 is mushroom-shaped, and the rotating rod 9 is sleeved with the first clamping plate 6, the transmission bevel gear 13, the driven bevel gear 14 and the first worm gear 17. The rotating rod 9 is fitted and connected with the connecting rod 11, and the planetary bevel gear 12 is rotatably sleeved with the first inner cavity 10.

[0023] Please see Figure 4 The second conveyor belt 15 and the lead screw 19 are both rotatably sleeved with the first clamping plate 6, and the second conveyor belt 15 is fitted and connected with the groove 16.

[0024] Specifically, during the plate cutting process, the plate is placed on the workbench 2, with one end positioned between the first pressure roller 22 and the second pressure roller 25. Then, the motor 8 on the workbench 2 is started, causing the motor 8 to drive the connecting rod 11 to rotate via the rotating rod 9. This causes the planetary bevel gear 12 on the connecting rod 11 to drive the transmission bevel gear 13 and the driven bevel gear 14 to rotate. As the transmission bevel gear 13 rotates, it drives the second conveyor belt 15 to rotate. The second conveyor belt 15 engages with the groove 16 on the bidirectional screw 4, allowing the second conveyor belt 15 to drive the bidirectional screw 4 to rotate. A first conveyor belt 5 is positioned between the two bidirectional screws 4, allowing them to rotate at the same speed and in the same direction. This causes the first clamping plate 6 and the second clamping plate 7 at both ends of the bidirectional screw 4 to move in opposite directions, pushing the plate to a designated position on the workbench 2, thus completing the plate positioning and initially restricting its movement. During this process, as the driven bevel gear 14... The rotation of the first worm gear 17 on the driven bevel gear 14 drives the first worm wheel 18 to rotate, causing the lead screw 19 on the first worm wheel 18 to drive the connecting rod 20 to move. The connecting rod 20 is slidably connected to the first clamping plate 6 and the second clamping plate 7, preventing the connecting rod 20 from rotating. Therefore, the connecting rod 20 descends under the drive of the lead screw 19, causing the pressure frame 21 on the connecting rod 20 to drive the first pressure roller 22 to descend until the first pressure roller 22 cooperates with the second pressure roller 25 to clamp the end of the plate, achieving the purpose of fully fixing the plate. The opposing movement of the second clamping plate 7 can drive the connecting rod 20 to move in the opposite direction, causing the pressure frame 21 and the bearing frame 23 to move in the opposite direction, changing the width of the conveying mechanism. At the same time, the descent of the pressure frame 21 can change the height of the conveying mechanism, allowing the first pressure roller 22 and the second pressure roller 25 to clamp the edge of the plate and drive the plate to move horizontally. Therefore, the adjustment of the clamp can be carried out synchronously with the adjustment of the conveying device, without the need for separate adjustment, saving time and effort. At the same time, the cutting device can adapt to the cutting of various plates, expanding the applicability of the device.

[0025] Example 2, please refer to Figure 2 , Figure 3 and Figures 5-8 The present invention provides a technical solution: a plate processing and cutting device, wherein a pressure frame 21 is fixedly connected to the end of a connecting rod 20, a first pressure roller 22 is hinged inside the pressure frame 21, a bearing frame 23 is fixedly connected to the side wall of a second clamping plate 7, a second pressure roller 25 is hinged inside the bearing frame 23, and a second inner cavity 24 is opened in the side wall of the bearing frame 23, a magnetic ring 26 is fixedly connected to the end of the second pressure roller 25, a coil 27 is sleeved on the magnetic ring 26, two pressure frames 21 are provided, a telescopic rod 28 is fixedly connected between the two pressure frames 21, and a third inner cavity 29 is opened in the side wall of the pressure frame 21.

[0026] Please see Figure 5 and Figure 6The first pressure roller 22 and the second pressure roller 25 are each provided with multiple coils 27. The coil 27 is fixedly connected to the side wall of the second inner cavity 24, and the coil 27 corresponds one-to-one with the second pressure roller 25. The ends of adjacent coils 27 are connected. The telescopic rod 28 can extend and retract in multiple stages.

[0027] Specifically, if the first clamping plate 6 and the second clamping plate 7 fix the plate before the first pressure roller 22, the transmission bevel gear 13 that indirectly drives the movement of the first clamping plate 6 and the second clamping plate 7 is fixed. As the rotating rod 9 continues to rotate, the connecting rod 11 still drives the planetary bevel gear 12 to revolve. The connecting rod 11 is rotatably connected to the planetary bevel gear 12, so that the planetary bevel gear 12 rotates on its own axis and revolves at the same time while being blocked by the transmission bevel gear 13, thus not affecting the rotation of the driven bevel gear 14, so that the first pressure roller 22 can still descend. Conversely, if the first pressure roller 22 fixes the plate before the first clamping plate 6 and the second clamping plate 7, the first clamping plate 6 and the second clamping plate 7 can still further fix the plate, which can adapt to the fixing of plates of various sizes, thereby ensuring the quality of plate cutting.

[0028] Example 3, please refer to Figures 7-9 The present invention provides a technical solution: a plate processing and cutting device, wherein a second worm gear 30 is rotatably connected to the side wall of the third inner cavity 29, a second worm wheel 31 is meshed with the outer surface of the second worm gear 30, a driving gear 32 is fixedly connected to the bottom surface of the second worm wheel 31, a driven gear ring 33 is meshed with the outer surface of the driving gear 32, a rotating sleeve 34 is fixedly connected to the inner surface of the driven gear ring 33, a guide groove 35 is opened on the inner surface of the rotating sleeve 34, a slider 36 is slidably connected in the guide groove 35, a top rod 37 is fixedly connected to the end of the slider 36, a guide rod 38 is fitted on the central axis of the top rod 37, a fixing rod 39 is fixedly connected to the top surface of the guide rod 38, and a return spring 40 is fixedly connected between the fixing rod 39 and the top rod 37.

[0029] Please see Figure 8 and Figure 9 The guide groove 35 is a single-turn spiral groove with the beginning and end connected. The cross-section of the guide rod 38 is mushroom-shaped. The fixing rod 39 is L-shaped and is fixed to the top surface of the pressure frame 21. The return spring 40 is sleeved on the guide rod 38. The top rod 37 is sleeved on the rotating sleeve 34. The end of the second worm gear 30 is fixed to the central axis of the first pressure wheel 22. The driven gear ring 33 is sleeved on the third inner cavity 29. The driving gear 32 is rotatably connected to the bottom surface of the third inner cavity 29.

[0030] Specifically, during the workpiece separation process, the coil 27 is energized, generating an induced magnetic field. This magnetic field drives the magnetic ring 26 to rotate, causing the second pressure roller 25 on the magnetic ring 26 to rotate. The second pressure roller 25, in conjunction with the first pressure roller 22, moves the cut sheet material horizontally. During this horizontal movement, the sheet material comes into contact with the first pressure roller 22 on the second worm gear 30. This causes the second worm gear 30 to rotate via the first pressure roller 22, resulting in the second worm wheel 31 on the second worm gear 30 rotating. Consequently, the driving gear 32 on the second worm wheel 31 drives the driven gear ring 33 to rotate, causing the rotating sleeve 34 on the driven gear ring 33 to rotate. This, in turn, causes the guide groove 35 on the rotating sleeve 34 to rotate clockwise, pressing the side wall of the guide groove 35 against the slider 36. The push rod 37 on block 36 is restricted from rotating by the guide rod 38, causing the slider 36 to fall under the pressure of the guide groove 35 and stretch the return spring 40 until the slider 36 moves to the bottom of the guide groove 35. At this time, the guide groove 35 no longer restricts the upward movement of the slider 36, allowing the slider 36 and push rod 37 to return to their original positions under the rebound of the return spring 40. The above process is repeated, allowing the push rod 37 to rise and fall repeatedly, thereby allowing the push rod 37 to extend out of the rotating sleeve 34 and impact the cut plate, causing the workpiece to fall off the plate skeleton, achieving the purpose of separating the workpiece from the waste. There is no need to use manual knocking, robotic gripping, special vibration devices or sorting equipment, which not only reduces the cost input, but also facilitates continuous processing. There is no need to coordinate the processing efficiency of the separation equipment and this device, saving time and labor.

[0031] The working principle and usage process of this invention are as follows: When it is necessary to cut a plate, the plate is placed on the workbench 2, and one end of the plate is positioned between the first pressure roller 22 and the second pressure roller 25. At this time, the motor 8 on the workbench 2 is started, so that the motor 8 drives the connecting rod 11 to rotate through the rotating rod 9. The planetary bevel gear 12 on the connecting rod 11 drives the transmission bevel gear 13 and the driven bevel gear 14 to rotate. As the transmission bevel gear 13 rotates, the transmission bevel gear 13 can drive the second conveyor belt 15 to rotate. The second conveyor belt 15 is engaged with the groove 16 on the bidirectional screw 4, so that the second conveyor belt 15 can drive the bidirectional screw 4 to rotate. The first conveyor belt 5 is provided between the two bidirectional screws 4, so that the two bidirectional screws 4 can rotate at the same speed and in the same direction. This causes the first clamping plate 6 and the second clamping plate 7 at both ends of the bidirectional screw 4 to move in opposite directions, thereby pushing the plate and positioning it at the designated position on the workbench 2, completing the positioning of the plate and initially restricting its movement. During the above process, as the driven bevel gear 14 rotates, the first worm gear 17 on the driven bevel gear 14 drives the first worm wheel 18 to rotate, causing the lead screw 19 on the first worm wheel 18 to drive the connecting rod 20 to move. The connecting rod 20 is slidably connected to the first clamping plate 6 and the second clamping plate 7, preventing the connecting rod 20 from rotating. Therefore, the connecting rod 20 descends under the drive of the lead screw 19, causing the pressure frame 21 on the connecting rod 20 to drive the first pressure roller 22 to descend until the first pressure roller 22, in conjunction with the second pressure roller 25, clamps the end of the plate, achieving full clamping. The purpose of fixing the plate is to move the connecting rod 20 in opposite directions, which in turn moves the pressure frame 21 and the bearing frame 23 in opposite directions, changing the width of the conveying mechanism. At the same time, the lowering of the pressure frame 21 can change the height of the conveying mechanism, so that the first pressure roller 22 and the second pressure roller 25 can clamp the edge of the plate and move the plate horizontally. Therefore, the adjustment of the clamp can be carried out synchronously with the adjustment of the conveying device, without the need for separate adjustment, saving time and effort. At the same time, the cutting device can adapt to the cutting of various plates, expanding the application range of the device. It should be further explained that if the first clamping plate 6 and the second clamping plate 7 fix the plate before the first pressure roller 22, the transmission bevel gear 13 that indirectly drives the movement of the first clamping plate 6 and the second clamping plate 7 is fixed. As the rotating rod 9 continues to rotate, the connecting rod 11 still drives the planetary bevel gear 12 to revolve. The connecting rod 11 is rotatably connected to the planetary bevel gear 12, so that the planetary bevel gear 12 rotates on its own axis and revolves at the same time while being blocked by the transmission bevel gear 13, thus not affecting the rotation of the driven bevel gear 14, so that the first pressure roller 22 can still descend. Conversely, if the first pressure roller 22 fixes the plate before the first clamping plate 6 and the second clamping plate 7, the first clamping plate 6 and the second clamping plate 7 can still further fix the plate, which can adapt to the fixing of plates of various sizes, thereby ensuring the quality of plate cutting. After the laser cutting machine body 1 completes the cutting of the sheet metal, the coil 27 is energized, causing it to generate an induced magnetic field. This magnetic field drives the magnetic ring 26 to rotate, causing the second pressure roller 25 on the magnetic ring 26 to rotate. The second pressure roller 25, in conjunction with the first pressure roller 22, moves the cut sheet metal horizontally. During this horizontal movement, the sheet metal comes into contact with the first pressure roller 22 on the second worm gear 30. This causes the sheet metal to drive the second worm gear 30 to rotate via the first pressure roller 22, resulting in the second worm wheel 31 on the second worm gear 30 rotating. This causes the driving gear 32 on the second worm wheel 31 to drive the driven gear ring 33 to rotate, causing the rotating sleeve 34 on the driven gear ring 33 to rotate. Consequently, the guide groove 35 on the rotating sleeve 34 rotates clockwise, causing the side wall of the guide groove 35 to press down on the slider 36. The push rod 37 on 36 is restricted from rotating by the guide rod 38, causing the slider 36 to fall under the pressure of the guide groove 35 and stretch the return spring 40 until the slider 36 moves to the bottom of the guide groove 35. At this time, the guide groove 35 no longer restricts the upward movement of the slider 36, allowing the slider 36 and the push rod 37 to return to their original positions under the rebound of the return spring 40. The above process is repeated, allowing the push rod 37 to rise and fall repeatedly, thereby allowing the push rod 37 to extend out of the rotating sleeve 34 and impact the cut plate, causing the workpiece to fall off the plate skeleton, achieving the purpose of separating the workpiece from the waste. There is no need to use manual knocking, robotic gripping, special vibration devices or sorting equipment, which not only reduces the cost input, but also facilitates continuous processing. There is no need to coordinate the processing efficiency of the separation equipment and this device, saving time and effort to complete the operation.

For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
