Description

Technical Field

[0001] The present invention relates to the technical field of laser cutting machines, and in particular to a laser cutting machine with an auxiliary precision cutting function. Background Art

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a cut is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] The existing laser cutting machines gradually exposed their shortcomings during use, mainly in the following aspects: First, the continuous processability is low. Specifically, when cutting metal sheets, the laser cutting gun is first reset to the origin, and then the uncut area of ​​the metal sheet is adjusted accordingly to ensure that the moving range of the laser cutting gun nozzle is in the uncut area of ​​the metal sheet. After the laser cutting gun completes cutting, the staff will take out the cut body, and the laser cutting gun will cut the residual area of ​​the metal sheet again. After the staff takes out the residual material of the metal sheet, the laser cutting gun is reset to the origin, and the above operation steps are repeated to continuously cut the metal sheet. During the entire cutting process, the staff not only needs to continuously take out the cut body and the residual material of the metal sheet, but also needs to drag the metal sheet back and forth to adjust the cutting position. Therefore, the unnecessary waiting time in the continuous cutting process is long, resulting in low continuous processability.

[0004] Second, the cutting accuracy is low, resulting in a high waste rate of metal sheets. Specifically, when cutting metal sheets, workers need to drag the metal sheets to adjust their position. The manual adjustment method has low accuracy, so it cannot prevent the laser cutting gun from moving the nozzle outside the metal sheet during the cutting process, resulting in failure of the cutting process. Usually, there is a lot of margin margin left in the metal sheet, so there is a lot of residual metal sheet after cutting, resulting in a high waste rate of metal sheets.

[0005] Third, the degree of automation in the cutting process is low, resulting in low cutting efficiency. Specifically, the removal of the cutting body and metal sheet waste and the adjustment of the metal sheet in the entire cutting process all require manual operation. Therefore, the degree of automation in the metal sheet cutting process is low, which in turn affects the cutting efficiency of the metal sheet.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. When cutting metal sheets, place the metal sheets on the rotating rollers and push them until their ends abut against the two stop plates. Drive the telescopic cylinder to drive the positioning plates to slide horizontally until the four positioning plates abut against the side walls of the metal sheets, and then accurately position the metal sheets. The three-axis mobile assembly drives the laser cutting gun to reset to the origin. At this time, the nozzle of the laser cutting gun is located directly above a corner of the metal sheet. The three-axis mobile assembly drives the laser cutting gun to move and cut the metal sheets between the four rotating rollers. The laser cutting machine can accurately adjust the position of the metal sheets, so that the laser cutting gun can accurately cut the metal sheets, reducing the boundary margin of the metal sheets, thereby reducing the waste of metal sheets. 2. After the metal sheet is positioned, the lifting and telescopic cylinder drives the vacuum suction cup to move upward until the vacuum suction cup contacts the area to be cut of the metal sheet and fixes it by adsorption (not repeated operation). After the metal sheet is cut, the vacuum suction cup fixes and adsorbs the cutting body. The lifting and telescopic cylinder drives the cutting body to descend and avoid the metal sheet. The control telescopic cylinder drives the cutting body to move above the product box. The first stepper motor drives the first rotating block and the cutting body to rotate downward. The second stepper motor drives the second rotating block and the cutting body to rotate to a horizontal state and put the cutting body in the product box. Then the first stepper motor drives the control telescopic cylinder to rotate The lifting and telescopic cylinder drives the vacuum suction cup to move horizontally to the preset position, and the lifting and telescopic cylinder drives the vacuum suction cup to move upward until the vacuum suction cup abuts against the area to be cut of the metal sheet, and the vacuum suction cup adsorbs and fixes the metal sheet (the adsorption position is the area to be cut next time). During this process, the control motor drives the driving shaft, the driven shaft and the driving gear to rotate, and the two driven racks respectively drive the upper driven plate and the lower driven plate to slide toward each other, thereby driving the stop plate and the clamping L-shaped plate to slide toward each other, until the metal sheet abuts against the clamping L-shaped plate, and the electric control telescopic cylinder drives the vacuum suction cup to move horizontally to the preset position. The lifting and telescopic cylinder drives the vacuum suction cup to move upward until the vacuum suction cup abuts against the area to be cut of the metal sheet, and the vacuum suction cup adsorbs and fixes the metal sheet (the adsorption position is the area to be cut next time). During this process, the control motor drives the driving shaft, the driven shaft and the driving gear to rotate, and the two driven racks drive the upper driven plate and the lower driven plate to slide toward each other, thereby driving the stop plate and the clamping L-shaped plate to slide toward each other, until the metal sheet abuts against the clamping L-shaped plate, and the electric control telescopic cylinder drives the vacuum suction cup to move upward until the vacuum suction cup abuts against the area to be cut of the metal sheet, and the vacuum suction cup adsorbs and fixes the metal sheet (the adsorption position is the area to be cut next time). The retracting cylinder drives the sliding clamping plate to slide downward and clamp the residual area of ​​the metal sheet. After the above two processes are completed synchronously, the three-axis mobile assembly drives the laser cutting gun to move and then cut the residual area of ​​the metal sheet. During the cutting process of the residual metal sheet, the telescopic cylinder drives the positioning plate to reset, and the driving motor drives the rotating shaft, rotating circular plate and rotating roller to rotate until the rotating roller avoids the residual metal sheet. After the residual metal sheet cutting is completed, the servo motor drives the driving rod, the driven rod, the rotating L-shaped plate and the clamping L-shaped plate to rotate downward to a certain angle, and the electric-controlled telescopic cylinder drives the sliding clamping plate to slide upward and then The metal sheet residue is released from the clamping, and the metal sheet residue falls into the residue box. After the metal sheet residue is processed, the driving motor drives the rotating roller to reset. At the same time, the servo motor and the control motor drive the rotating L-shaped plate and the stop plate to reset respectively, and the telescopic end of the telescopic cylinder is controlled to extend synchronously, thereby driving the metal sheet to move until the metal sheet hits the stop plate again. Repeat the above process (except for "non-subsequent repeated operations") to continuously cut the metal sheet. The laser cutting machine can greatly reduce the waiting time during the continuous cutting of the metal sheet, thereby improving the continuous processing of the metal sheet; 3. The laser cutting machine can also automatically and continuously cut metal sheets, with a high degree of automation, thereby improving the cutting efficiency of metal sheets; 4. When processing cutting bodies of different sizes and specifications, the distance between the sliding plate and the fixed plate is adjusted to match the width of the metal plate by adjusting the hydraulic telescopic cylinder, the distance between the opposing positioning plates is adjusted to match the width of the metal plate by adjusting the width adjustment telescopic cylinder, and the distance between adjacent positioning plates is adjusted to match the size of the cutting body by adjusting the length adjustment telescopic cylinder, thereby realizing the function of processing cutting bodies of different sizes and specifications and improving the practicability of the equipment.

The laser cutting machine can accurately adjust the position of the metal sheet 54, thereby enabling the laser cutting gun 7 to accurately cut the metal sheet 54, reducing the boundary margin of the metal sheet 54, thereby reducing the waste of the metal sheet 54; After the metal sheet 54 is positioned, the lifting and telescopic cylinder 49 drives the vacuum suction cup 48 to move upward until the vacuum suction cup 48 contacts the area to be cut of the metal sheet 54 and is adsorbed and fixed (not a subsequent repeated operation). After the cutting of the metal sheet 54 is completed, the vacuum suction cup 48 fixes and adsorbs the cutting body, and the lifting and telescopic cylinder 49 drives the cutting body to descend and avoid the metal sheet 54. The control telescopic cylinder 53 drives the cutting body to move above the product box 16. The first stepper motor 44 drives the first rotating block 46 and the cutting body to rotate downward. The second stepper motor 52 drives the second rotating block 51 and the cutting body to rotate to a horizontal state and put the cutting body in the product box 16. After that, the first stepper motor 44 drives the control telescopic cylinder 53 to rotate to a horizontal state. The second stepper motor 52 drives the lifting and telescopic cylinder 49 to rotate to a vertical state, and the control telescopic cylinder 53 drives the vacuum suction cup 48 to move horizontally to a preset position. The lifting and telescopic cylinder 49 drives the vacuum suction cup 48 to move upward until the vacuum suction cup 48 abuts against the area to be cut of the metal plate 54, and the vacuum suction cup 48 adsorbs and fixes the metal plate 54 (the adsorption position is the area to be cut next time). During this process, the control motor 43 drives the driving shaft 41, the driven shaft 32 and the driving gear 31 to rotate, and the two driven racks 36 respectively drive the upper driven plate 38 and the lower driven plate 30 to slide toward each other, thereby driving the stop plate 33 and the clamping L-shaped plate 34 to slide toward each other, until the metal plate 54 abuts against the clamping L-shaped plate 34, and the electric control telescopic cylinder 49 drives the vacuum suction cup 48 to move upward until the vacuum suction cup 48 abuts against the area to be cut of the metal plate 54, and the vacuum suction cup 48 adsorbs and fixes the metal plate 54 (the adsorption position is the area to be cut next time). During this process, the control motor 43 drives the driving shaft 41, the driven shaft 32 and the driving gear 31 to rotate, and the two driven racks 36 drive the upper driven plate 38 and the lower driven plate 30 to slide toward each other, thereby driving the stop plate 33 and the clamping L-shaped plate 34 to slide toward each other, until the metal plate 54 abuts against the clamping L-shaped plate 34, and the electric control telescopic cylinder 49 drives the vacuum suction cup 48 to move upward until the vacuum suction cup 48 abuts against the area to be cut of the metal plate 54, and the electric control telescopic cylinder 49 drives the vacuum suction cup 48 to move upward until the vacuum suction cup 48 a The cylinder 37 drives the sliding clamping plate 35 to slide downward and clamp the residual area of ​​the metal sheet 54. After the above two processes are completed synchronously, the three-axis mobile assembly 19 drives the laser cutting gun 7 to move and then cut the residual area of ​​the metal sheet 54. During the cutting process of the residual material of the metal sheet 54, the telescopic cylinder 27 is driven to drive the positioning plate 25 to reset, and the driving motor 21 drives the rotating shaft 28, the rotating circular plate 22 and the rotating roller 23 to rotate until the rotating roller 23 avoids the residual material of the metal sheet 54. After the residual material cutting of the metal sheet 54 is completed, the servo motor 40 drives the driving rod 29, the driven rod 42, the rotating L-shaped plate 39 and the clamping L-shaped plate 34 to rotate downward to a certain angle, and the electric-controlled telescopic cylinder 37 drives the sliding clamping plate 35 to The metal sheet 54 is then released from the clamping state by sliding upward, and the metal sheet 54 residue falls into the residue box 15. After the metal sheet 54 residue is processed, the driving motor 21 drives the rotating roller 23 to reset. At the same time, the servo motor 40 and the control motor 43 respectively drive the rotating L-shaped plate 39 and the stop plate 33 to reset, and control the telescopic end of the telescopic cylinder 53 to extend synchronously, thereby driving the metal sheet 54 to move until the metal sheet 54 abuts against the stop plate 33 again. The above process is repeated (except for "non-subsequent repeated operations") to continuously cut the metal sheet 54. The laser cutting machine can significantly reduce the waiting time during the continuous cutting of the metal sheet 54, thereby improving the continuous processing of the metal sheet 54. The laser cutting machine can also automatically and continuously cut the metal sheet 54, with a high degree of automation, thereby improving the cutting efficiency of the metal sheet 54; When processing cutting bodies of different sizes, the distance between the sliding plate 5 and the fixed plate 3 is adjusted to match the width of the metal plate 54 by adjusting the hydraulic telescopic cylinder 6, the distance between the opposing positioning plates 25 is adjusted to match the width of the metal plate 54 by adjusting the width adjustment telescopic cylinder 9, and the distance between adjacent positioning plates 25 is adjusted to match the size of the cutting body by adjusting the length adjustment telescopic cylinder 8, thereby realizing the function of processing cutting bodies of different sizes and improving the practicability of the equipment.
