Description

Technical Field

[0001] The invention relates to the technical field of shearing machines, in particular to a laser-assisted leveling cross-cutting shearing machine. Background Art

[0002] To accommodate the continuous processing of metal coils, cross-cut shears integrate uncoiling, leveling, cut-to-length cutting, and stacking functions to form an integrated production line. With advancements in precision control, cutting tools, shearing processes, and CNC technology, cross-cut shears address the problems of accumulated flatness errors, shearing size deviations, and lengthy die-changing times associated with traditional mechanical leveling and shearing.

[0003] The diameter of the traditional laser focus spot is greater than 0.1mm, resulting in high incision roughness, which cannot meet the needs of precision processing. At the same time, the heat generated during the laser cutting process cannot be utilized. The heat generated at the cutting position will cause local temperature rise of the plate, and thermal stress will cause deformation of the plate, which cannot meet the high flatness requirements.

[0004] Patent CN118478044B discloses a hydraulic shearing machine, which can flatten the plate from the middle to both sides, thereby avoiding the bulge of the plate.

[0005] The above patent sets up evenly arranged fan-shaped blocks, and the arc length of the middle fan-shaped block is the longest, and the arc lengths of the fan-shaped blocks on both sides of the middle fan-shaped block become shorter in sequence. Therefore, in the process of different fan-shaped blocks following the rotation of the drive shaft, the middle fan-shaped block will first squeeze the pressing assembly downward. After the downward pressing assembly contacts the plate, the plate can be flattened by using the pressing plate. After the pressing plate on the middle pressing assembly is fitted with the plate, the fan-shaped blocks on both sides of the middle fan-shaped block will contact the lower pressing assembly, squeeze the pressing assembly downward, and flatten the plate. Then the remaining fan-shaped blocks will press down the lower pressing assembly in turn, so that the plate can be flattened again. In this process, the plate can be flattened from the middle to both sides in turn, thereby avoiding the situation where bulges still appear after the plate is fixed, thereby affecting the plate shearing process. There is room for optimization in laser cutting accuracy.

[0006] To this end, the present application proposes a laser-assisted leveling cross-cutting shearing machine for precise laser cutting. Summary of the Invention

During the cutting process of the plate, the vibration information of the plate is collected by the vibration sensor 26 located on the left side of the outer wall of the fixed block 25, and the information is transmitted to the controller 4. The controller 4 adjusts the thrust of the return rod 28 to the fixed block 25 according to the vibration information of the plate, thereby changing the fixing effect of the fixed block 25 on the plate, avoiding the influence of the plate vibration on the shearing of the plate by the cutting head 35, realizing the function of double fixing of the plate, solving the problem that the plate offset reduces the shearing accuracy and aggravates the wear of the device, avoiding the offset of the plate during the shearing process, improving the shearing accuracy of the plate, improving the processing efficiency and processing efficiency of the device, and extending the service life of the device.

[0071] Example 5: Please refer to Figure 1 、 Figure 5 and Figure 6 , a laser-assisted leveling cross-cutting shearing machine, wherein the outer wall of the conveyor belt 2 is provided with an offset module on both sides thereof, and the offset module comprises: a fixed block 25, a vibration sensor 26, a visual sensor 27 and a return rod 28;

[0072] Fixed blocks 25 are symmetrically installed on the front and rear sides of the outer wall of the conveyor belt 2. A return rod 28 is installed on the rear side of the outer wall of the fixed block 25. The return rod 28 is connected to the laser motor 8 through a connecting shaft. A visual sensor 27 is installed on the upper side of the outer wall of the fixed block 25. A vibration sensor 26 is installed on the left side of the outer wall of the fixed block 25. The vibration sensor 26 and the visual sensor 27 are connected to the controller 4 through signal lines.

[0073] The cutting unit 7 includes: a second slide 29, a second slider 30, a telescopic rod 31, an infrared sensor 32, a rotating shaft 33, an angle sensor 34 and a cutting head 35;

[0074] A second chute 29 is installed on the upper side of the outer wall of the conveyor belt 2, a second slider 30 is installed in the middle of the inner wall of the second chute 29, a telescopic rod 31 is installed on the lower side of the outer wall of the second slider 30, a rotating shaft 33 is installed on the lower side of the outer wall of the telescopic rod 31, a cutting head 35 is installed on the lower side of the outer wall of the rotating shaft 33, an infrared sensor 32 is installed on the left side of the outer wall of the telescopic rod 31, and an angle sensor 34 is installed on the right side of the outer wall of the telescopic rod 31. The infrared sensor 32 and the angle sensor 34 are connected to the controller 4 via signal lines, and the second slider 30, the telescopic rod 31 and the rotating shaft 33 are respectively connected to the laser motor 8 via connecting shafts;

[0075] Furthermore, when facing the cutting of plates that require complex patterns or curves, the infrared sensor 32 is used to collect the distance between the cutting head 35 and the plate, and according to the required pattern or curve, the controller 4 controls the offset modules located on the front and rear sides of the conveyor belt 2 to adjust the front and rear position of the plate. The controller 4 controls the laser motor 8 to drive the return rod 28 to adjust the telescopic length of the two fixed blocks 25 in front and rear of the conveyor belt 2, so that the plate on the conveyor belt 2 moves in the front and rear directions. At the same time, the controller 4 controls the dynamic rotating shaft 33 of the laser motor 8 to adjust the angle of the cutting head 35. The angle sensor 34 collects the angle adjustment information of the cutting head 35 in real time and transmits the angle adjustment information to the controller 4. Through the coordinated action of the offset module, the rotating shaft 33 and the conveyor belt 2, the pattern information is collected by the visual sensor 27 during the cutting process and the information is transmitted to the controller 4. The controller 4 compares the input curve or pattern information to ensure that the pattern or curve is cut accurately. When complex patterns or curves need to be cut, through multi-directional coordinated control, the device can adapt to most complex curve trajectories and improve the cutting efficiency of the device.

[0076] Working principle: The operator puts the plate to be cut onto the conveyor belt 2, and the feeding module located on the left side of the conveyor belt 2 processes the plate. The laser sensor 24 collects the flatness information of the plate and transmits the information to the controller 4. The controller 4 controls the conveying motor 3 to drive the first slider 21 to move in the first slide 20 according to the flatness information of the plate surface, and moves the leveling blocks 19 on the upper and lower sides of the plate to the uneven place of the plate. Then, the conveying motor 3 is controlled to drive the lifting rod 23 to push the leveling block 19 to squeeze the plate to complete the leveling process of the plate. According to the stain information on the plate surface transmitted by the laser sensor 24, the controller 4 controls the first slider 21 to move the leveling block 19 to the stain position during the plate conveying process. The cleaning brush 22 cleans the stains on the surface of the plate during the plate conveying process, and controls the movement of the first slider 21 to drop the cleaned stains into the recovery tank 44. The controller 4 controls the switching valve 17 to connect the recovery tank 44 and the cleaning box 14, and recycles the cleaned stains into the cleaning box 14;

[0077] Before the plate enters the laser module and starts shearing, the controller 4 controls the laser motor 8 to drive the return rods 28 located on the front and rear sides of the conveyor belt 2 to push the fixed blocks 25 on both sides of the conveyor belt 2 to fix the plate to be sheared. Then the controller 4 controls the laser motor 8 to drive the second slider 30 to move in the second slide groove 29 to move the cutting head 35 to the cutting position. Then the laser motor 8 is controlled to drive the telescopic rod 31 to move downward to fit the lower surface of the protective cover 12 with the upper surface of the plate to fix the plate for the second time. During the cutting process of the plate, the vibration information of the plate is collected by the vibration sensor 26 located on the left side of the outer wall of the fixed block 25, and the information is transmitted to the controller 4. The controller 4 adjusts the thrust of the return rod 28 to the fixed block 25 according to the vibration information of the plate, so that the fixing effect of the fixed block 25 on the plate changes, thereby avoiding the influence of the plate vibration on the shearing of the plate by the cutting head 35.

[0078] After the plate enters the laser module and is fixed, the controller 4 controls the laser 5, the laser 5 generates a laser beam, and transmits the laser beam to the cutting unit 7 through the transmission light path 6. After the transmission light path 6 transmits the laser generated by the laser 5 into the optical fiber interface 36, the lens group 37 processes the laser, and the collimator 46 converts the divergent light into parallel light, and then the focusing lens 47 converges the parallel light into a micron-level light spot with a diameter of 0.01mm to 0.03mm. During the laser conversion process, the protective mirror 48 located between the collimator 46 and the focusing lens 47 is used to ensure sealing. After the laser conversion is completed, the controller 48 is used to control the laser 5. The controller 4 controls the gas box 39 to provide shielding gas for the nozzle 38, so that the shielding gas and the light spot act on the surface of the plate at the same time to cut the plate. During the cutting process, the circulation pipe 10 exchanges heat with the water flow in the water tank 9 through the connecting valve 11, and exchanges the heat generated by the laser 5 and the cutting unit 7 when they are working, so as to avoid the laser 5 and the cutting unit 7 from malfunctioning due to excessive temperature. At the same time, the heated water flows through the circulation pipe 10 to flow under the conveyor belt 2, so as to absorb the heat generated when the laser cuts the plate, and at the same time avoid the temperature conversion rate being too fast to cause the plate to malfunction. When the cutting unit 7 needs to be temperature compensated During compensation, the water temperature in the circulation pipe 10 can be changed by connecting the valve 11, so that the cutting unit 7 works within the temperature range of 15℃~30℃. When facing the cutting of plates that require complex patterns or curves, the distance between the cutting head 35 and the plate is collected by the infrared sensor 32, and according to the required pattern or curve, the controller 4 controls the offset modules located on the front and rear sides of the conveyor belt 2 to adjust the front and rear position of the plate. The controller 4 controls the laser motor 8 to drive the return rod 28 to adjust the telescopic length of the two fixed blocks 25 on the front and rear of the conveyor belt 2, so that the plate on the conveyor belt 2 moves in the front and rear directions. At the same time, the controller 4 controls the rotating shaft 33 of the laser motor 8 to adjust the angle of the cutting head 35. The angle sensor 34 collects the angle adjustment information of the cutting head 35 in real time and transmits the angle adjustment information to the controller 4. Through the coordinated action of the offset module, the rotating shaft 33 and the conveyor belt 2, the pattern information is collected by the visual sensor 27 during the cutting process and the information is transmitted to the controller 4. The controller 4 compares the input curve or pattern information to ensure that the pattern or curve is cut accurately. When complex patterns or curves need to be cut, the device can adapt to most complex curve trajectories through multi-directional coordinated control.

[0079] After the protective cover 12 is attached to the surface of the plate, the controller 4 idles the laser module to cut the plate. During the cutting process, the controller 4 controls the on-off valve 13 to open, and controls the switching valve 17 to connect the protective cover 12, the fan 15 and the cleaning box 14. During the cutting process, the controller 4 controls the cleaning motor 18 to drive the fan 15 to rotate, generating suction in the connecting pipe, sucking the waste gas and debris generated during the plate cutting process into the connecting pipe through the on-off valve 13, and entering the cleaning box 14 through the adjustment of the switching valve 17. After the shearing is completed, the controller 4 controls the cleaning motor 18 to drive the push rod 43 to move the piston 41. Pull to suck the water flow in the water tank 9 into the pressurizing chamber 40, then reset the piston 41, pressurize the water flow and switch the connection through the switching valve 17, connect the pressurizing unit 16 and the opening and closing valve 13, and spray the pressurized water flow into the protective cover 12 to clean the cutting position of the plate. During the pressurization process of the water flow in the pressurizing chamber 40, the balance pipe 42 maintains the pressure balance in the pressurizing chamber 40. After the shearing is completed, the controller 4 controls the cleaning port 45 to connect the pressurizing unit 16, pressurize the water flow in the water tank 9 and spray it out from the cleaning port 45. While the cleaning brush 22 cleans the surface of the plate, the pressurized water flow cleans the surface of the plate.
