Description

Technical Field

[0001] The invention relates to a laser cutting device, in particular to a laser cutting device for special-shaped sheet metal parts, belonging to the technical field of laser cutting. Background Art

[0002] Laser cutting machine is to focus the laser light 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 the melting point or boiling point, and 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, the material is eventually cut, thus achieving the purpose of cutting.

[0003] However, problems often occur during the laser cutting process, especially when processing metal materials such as sheet metal. For example, when the laser cutting machine uses laser to cut sheet metal, the completely cut high-temperature waste forms sparks that fly everywhere.

[0016] The present invention provides a laser cutting device for special-shaped sheet metal parts, which has the following beneficial effects:

[0017] 1. The laser cutting equipment for special-shaped sheet metal parts, with the cooperation of telescopic pneumatic cylinder four and telescopic pneumatic cylinder three, the special-shaped sheet metal parts newly cut and formed by the laser cutting machine and the special-shaped sheet metal parts formed last are supported by the supporting structure and cannot fall, ensuring that the debris and impurities on the top of the special-shaped sheet metal parts are polished away by the grinding head before falling into the collection box that moves synchronously with the transmission part two. The collection box collects the special-shaped sheet metal parts cut and formed by the laser cutting machine, ensuring the cost investment required for collection and reprocessing of the special-shaped sheet metal parts after cutting and forming, thereby reducing the processing cost of special-shaped sheet metal parts.

[0018] 2. When the forward and reverse motors of the laser cutting equipment for the special-shaped sheet metal work again, the telescopic pneumatic cylinder four contracts during the movement of the transmission part two, so that the mounting frame five and the supporting roller two and the transmission part two move relative to each other, and the multiple supporting rollers two maintain the supporting state for the new special-shaped sheet metal. The telescopic pneumatic cylinder three extends, and the mounting frame four moves to the bottom of the laser cutting machine to support the sheet metal plate at the bottom of the laser cutting machine, and supports the special-shaped sheet metal to be cut and processed by the laser cutting machine next time.

[0019] 3. In the laser cutting equipment for the special-shaped sheet metal parts, the grinding head fixedly installed at the bottom output end of the dual-axis motor covers the top of the previous special-shaped sheet metal part, and the bottom and outer side of the previous special-shaped sheet metal part are limited by multiple support rollers and sheet metal plates. At this time, the working dual-axis motor drives the grinding head to rotate, and the rotating grinding head grinds the top of the special-shaped sheet metal part, and the debris generated by the laser cutting on the top of the special-shaped sheet metal part is cooled and the sticky debris and impurities are ground away to ensure the quality of the processing and forming of the special-shaped sheet metal parts.

[0020] 4. For the laser cutting equipment of the special-shaped sheet metal, when the dual-axis motor is working, the transmission part 1 cannot rotate and move up and down under the drive of the reciprocating screw rod. When the dual-axis motor drives the grinding head to rotate and grind the top of the previous special-shaped sheet metal, the transmission part 1 drives the pusher rack to move up and down and then reset. During the up and down movement of the pusher rack, since the position of the previous special-shaped sheet metal cut by the laser cutting machine is set at the bottom of the pusher rack, if the special-shaped sheet metal cannot be separated from the sheet metal plate due to solidification of debris, the pusher rack moves to push the special-shaped sheet metal to fall. Since the collection box installed on the transmission part 2 is larger, the previous special-shaped sheet metal falls into the collection box, avoiding the situation that the special-shaped sheet metal part is fixed on the sheet metal plate again due to the solidification of part of the debris due to the small cutting gap, so that the special-shaped sheet metal part cannot be separated from the sheet metal plate.

[0033] Specifically, when the laser cutting device composed of the laser cutting structure 1 for supporting the cutting of the sheet metal plate 4, the auxiliary structure 2 for grinding the special-shaped sheet metal part 5, and the supporting structure 3 for supporting the special-shaped sheet metal part 5 is working, the human-machine interaction device 12 in the laser cutting structure 1 controls the position control component, the laser cutting machine 19, the auxiliary structure 2, the supporting structure 3 and other structures to work according to the program stored in advance inside, so that the laser cutting machine 19 cuts the special-shaped sheet metal part 5 from the sheet metal plate 4;

[0034] First, since a plurality of clamping plates 112 are symmetrically arranged on both sides of the processing box 11, a plurality of L-shaped clamping plates 112 form a U-shaped clamping space. After the sheet metal plate 4 is placed in the U-shaped clamping space, the telescopic pneumatic cylinder 111 fixedly connected between the plurality of clamping plates 112 and the adjacent inner wall of the processing box 11 is controlled to work. At this time, the plurality of telescopic pneumatic cylinders 111 push the plurality of clamping plates 112 distributed on both sides of the sheet metal plate 4 to move toward the outside of the sheet metal plate 4 at the same time, and the plurality of telescopic pneumatic cylinders 111 temporarily After stopping work, multiple clamping plates 112 clamp and fix the sheet metal plate 4 to ensure the stability of the sheet metal plate 4 when being cut by the laser cutting machine 19 and polished by the auxiliary structure 2. The sheet metal plate 4 is clamped and fixed by cooperating with multiple telescopic pneumatic cylinders 111 and multiple clamping plates 112. When the laser cutting machine 19 moves near a certain clamping plate 112, the telescopic pneumatic cylinder 111 on one side of the clamping plate 112 contracts to drive the clamping plate 112 away from the sheet metal plate 4, thereby providing space for the laser cutting machine 19 to process.

[0035] Subsequently, the human-computer interaction device 12 controls the forward and reverse motor 16 of the position control component to work. Since the fixed plate 13 and the fixed plate 2 15 in the position control component are fixedly installed together with the processing box 11, a driving screw 14 is rotatably installed inside the fixed plate 13, and one end of the driving screw 14 is fixedly connected to the output end of the forward and reverse motor 16 fixedly installed on the fixed plate 2 15. Therefore, the working forward and reverse motor 16 causes the driving screw 14 to rotate, and the rotating driving screw 14 drives the support trolley 17 installed on the outside through the nut pair to move. Since the multiple rollers installed at the bottom of the support trolley 17 are in contact with the ground, and the telescopic pneumatic cylinder 2 35 fixedly connected to the support trolley 17 passes through the guide groove 110 opened on the processing box 11, under the support limit of the telescopic pneumatic cylinder 2 35 and the multiple rollers, the support trolley 17 can only Horizontal movement is performed on the outside of the driving screw rod 14. The industrial robot arm 18 in the position control component is fixedly installed on the top of the supporting trolley 17, and the end of the industrial robot arm 18 is fixedly installed together with the laser cutting machine 19, so the supporting trolley 17 drives the industrial robot arm 18 and the laser cutting machine 19 to perform horizontal movement. The forward and reverse motors 16 are controlled to work forward and reversely to control the position of the laser cutting machine 19. After the laser cutting machine 19 cuts a special-shaped sheet metal part 5 on the sheet metal plate 4, the forward and reverse motors 16 work once. Under the action of the driving screw rod 14 and the supporting trolley 17, the industrial robot arm 18 and the laser cutting machine 19 move to the next processing position. The industrial robot arm 18 controls the laser cutting machine 19 to perform multi-position movement. The laser cutting machine 19 generates laser to cut the special-shaped sheet metal part 5 on the sheet metal plate 4.

[0036] At the same time, the supporting trolley 17 drives the fixedly connected telescopic pneumatic cylinder 2 35 to move synchronously. Since the piston end of the telescopic pneumatic cylinder 2 35 is fixedly connected to the transmission member 2 34, the telescopic pneumatic cylinder 2 35 drives the transmission member 2 34 to move synchronously. The transmission member 2 34 and the laser cutting machine 19 are synchronously displaced in the lateral direction. The telescopic pneumatic cylinder 3 313 and the telescopic pneumatic cylinder 4 315 fixedly installed on the transmission member 2 34 move synchronously. Since one end of the extended telescopic pneumatic cylinder 3 313 is fixedly connected to the transmission member 5 314, as shown in FIG. Figure 8 As shown, a transmission member 36 is fixedly connected between the transmission member 5 314 and the mounting frame 4 37, and a plurality of support rollers 38 are rotatably connected inside the mounting frame 4 37 to abut against the bottom of the sheet metal plate 4, and the plurality of support rollers 38 are located at the bottom of the laser cutting machine 19. At this time, the special-shaped sheet metal part 5 cut and formed by the laser cutting machine 19 is supported by the plurality of support rollers 38 and cannot fall, as shown in FIG. Figure 6 As shown; the mounting frame 6 319 on which the transmission member 2 34 is slidably mounted is fixedly connected to two transmission members 6 317, so after one transmission member 6 317 is forced to move, the other transmission member 6 317 moves synchronously under the action of the mounting frame 6 319, and the telescopic pneumatic cylinder 4 315 is fixedly connected to one of the transmission members 6 317, so the telescopic pneumatic cylinder 4 315 in the contracted state controls the two transmission members 6 317 at one end of the transmission member 2 34 away from the transmission member 5 314, and the two transmission members 6 317 are respectively A transmission member 439 is fixedly connected between the two mounting frames 510, and the mounting frames 510 and the transmission member 6317 move synchronously. The telescopic pneumatic cylinder 4315 controls the positions of the two mounting frames 510 through the mounting frames 6319, the two transmission members 6317 and the two transmission members 439. The mounting frames 510 are located on the side of the top of the transmission member 234 away from the mounting frames 437. At this time, the multiple supporting rollers 2311 rotatably connected inside the two mounting frames 510 abut against the bottom of the previous special-shaped sheet metal part 5, such as Figure 6 As shown, the previous special-shaped sheet metal part 5 is supported so that the previous special-shaped sheet metal part 5 cannot move up and down, and the gap produced by laser cutting is small, so the translation of the previous special-shaped sheet metal part 5 is blocked by the sheet metal plate 4;

[0037] The fixed plate 3 21 fixedly installed outside the laser cutting machine 19 is fixedly connected to the dual-axis motor 22, and the dual-axis motor 22 is located at the rear side of the laser cutting machine 19 in the forward direction. At this time, the grinding head 23 fixedly installed at the bottom output end of the dual-axis motor 22 covers the top of the previous special-shaped sheet metal part 5, such as Figure 6As shown, the bottom and outer side of the previous special-shaped sheet metal part 5 are limited by multiple supporting rollers 2 311 and the sheet metal plate 4. At this time, the working dual-axis motor 22 drives the grinding head 23 to rotate, and the rotating grinding head 23 grinds the top of the special-shaped sheet metal part 5, and the debris generated by the laser cutting on the top of the special-shaped sheet metal part 5 is cooled and the sticky debris impurities are ground away, so as to ensure the processing quality of the special-shaped sheet metal part 5;

[0038] The top of the mounting frame 25 in the transmission assembly is rotatably connected to the mounting frame 1 24, and the mounting frame 1 24 is fixedly connected to the fixing plate 3 21 and cannot rotate. Figure 4 As shown, the mounting frame 25 can rotate, and the reciprocating screw rod 26 fixedly connected to the bottom of the mounting frame 25 can also rotate. Two sprocket wheels 211 are arranged inside the chain 212 in the transmission assembly, and the two sprocket wheels 211 are respectively fixedly sleeved on the upper output end of the double-axis motor 22 and the outer top of the mounting frame 25. Therefore, when the double-axis motor 22 is working, the chain 212 and the two sprocket wheels 211 cooperate to drive the mounting frame 25 and the reciprocating screw rod 26 fixedly connected to the mounting frame 25 to rotate; and a transmission member 27 and a pusher frame 29 are sleeved on the outer side of the reciprocating screw rod 26, as shown in FIG. Figure 5 As shown, there are two fixed plates four 28 fixedly connected between the transmission member 27 and the pusher rack 29, and the rotating reciprocating screw 26 drives the transmission member 27 sleeved on the outside. Since the telescopic rod 210 fixedly connected to the mounting frame 24 is fixedly connected to one of the fixed plates four 28, the fixed plate four 28 is limited and cannot rotate, and the transmission member 27 cannot rotate and move up and down under the drive of the reciprocating screw 26; therefore, in the process of the dual-axis motor 22 driving the grinding head 23 to rotate and grind the top of the previous special-shaped sheet metal part 5, the transmission member 27 drives the pusher rack 29 to move up and down and then reset. In the process of the pusher rack 29 moving up and down, since the position of the previous special-shaped sheet metal part 5 cut by the laser cutting machine 19 is set at the bottom of the pusher rack 29, as shown in FIG. When the special-shaped sheet metal part 5 cannot be separated from the sheet metal plate 4 due to the solidification of the debris, the pusher rack 29 moves to push the special-shaped sheet metal part 5 down. Since the collection box 33 installed on the transmission member 2 34 is larger, the previous special-shaped sheet metal part 5 falls into the collection box 33 to avoid the special-shaped sheet metal part 5 being fixed on the sheet metal plate 4 again due to the small cutting gap, so that the special-shaped sheet metal part 5 cannot be separated from the sheet metal plate 4. Due to the splashing of debris, the amount of solidified debris between the sheet metal plate 4 and the special-shaped sheet metal part 5 is small, and the firmness between the sheet metal plate 4 and the special-shaped sheet metal part 5 is poor. Therefore, the up and down force generated by the cooperation of the reciprocating screw rod 26 and the transmission member 1 27 is sufficient to push the special-shaped sheet metal part 5 to separate from the sheet metal plate 4.

[0039] When the dual-axis motor 22 stops working, the grinding head 23 stops rotating, and the reset of the push rack 29 will not affect the movement of the auxiliary structure 2. At this time, the laser cutting machine 19 cuts the new special-shaped sheet metal part 5 into shape. The bottom of the new special-shaped sheet metal part 5 is supported by multiple support rollers 1 38 connected to the inside of the mounting frame 4 37 and cannot fall. The forward and reverse motors 16 work by driving the screw rod 14 to drive the support trolley 17. The support trolley 17 drives the industrial robot arm 18, the laser cutting machine 19 and the telescopic pneumatic cylinder 2 35 to move to the next working position. In this process, the telescopic pneumatic cylinder 2 35 drives the transmission part 2 34 to move. At the same time, people The machine interaction device 12 controls the electrically connected telescopic pneumatic cylinder 4 315 and telescopic pneumatic cylinder 3 313 to work, the telescopic pneumatic cylinder 4 315 works to extend, and the telescopic pneumatic cylinder 4 315 cooperates with two transmission parts 6 317, mounting frame 6 319 and two transmission parts 4 39 to control the movement of two mounting frames 5 310; the telescopic pneumatic cylinder 3 313 works to retract, and the telescopic pneumatic cylinder 3 313 controls the movement of mounting frame 4 37 through transmission parts 5 314 and transmission parts 3 36, so that the mounting frame 4 37 and the moving transmission part 2 34 achieve a relative movement effect, and the transmission part 2 34 maintains the state of supporting the new special-shaped sheet metal part 5;

[0040] After the forward and reverse motors 16 finish working, the transmission member 2 34 stops moving. At this time, the two mounting frames 5 310 are located at the bottom of the laser cutting machine 19. The support rollers 2 311 rotatably connected inside the two mounting frames 5 310 support the sheet metal plate 4 at the bottom of the laser cutting machine 19. The multiple support rollers 2 311 support the special-shaped sheet metal parts 5 that are about to be processed by the laser cutting machine 19. When the laser cutting machine 19 works again and cuts off a new special-shaped sheet metal part 5 from the sheet metal plate 4 at the bottom, the special-shaped sheet metal part 5 is supported by the multiple support rollers 2 311 support, when the forward and reverse motors 16 work again, the telescopic pneumatic cylinder four 315 contracts during the movement of the transmission part 2 34, so that the mounting frame five 310 and the support roller two 311 and the transmission part 2 34 move relative to each other, and the multiple support rollers two 311 maintain the supporting state for the new special-shaped sheet metal part 5, the telescopic pneumatic cylinder three 313 extends, and the mounting frame four 37 moves to the bottom of the laser cutting machine 19 to support the sheet metal plate 4 at the bottom of the laser cutting machine 19, and supports the special-shaped sheet metal part 5 to be cut and processed by the laser cutting machine 19 next time.

[0041] With the cooperation of telescopic pneumatic cylinder four 315 and telescopic pneumatic cylinder three 313, the newly cut and formed special-shaped sheet metal part 5 by the laser cutting machine 19 and the previously formed special-shaped sheet metal part 5 are supported by the supporting structure 3 and cannot fall, ensuring that the debris and impurities on the top of the special-shaped sheet metal part 5 are polished away by the polishing head 23 before falling into the collection box 33 that moves synchronously with the transmission part 2 34. The collection box 33 collects the special-shaped sheet metal parts 5 cut and formed by the laser cutting machine 19, ensuring the cost investment required for collecting and reprocessing the special-shaped sheet metal parts 5 after cutting and forming, thereby reducing the processing cost of the special-shaped sheet metal parts 5.

[0042] In addition, such as Figure 2 and Figure 3 As shown, an extension plate 113 is fixedly connected to the bottom of one end of the processing box 11. After the laser cutting machine 19 moves to the inside of the processing box 11 away from the end of the extension plate 113, the forward and reverse motors 16, the driving screw rod 14, the supporting trolley 17 and other structures cooperate to control the laser cutting machine 19 to reset. At this time, the collection box 33 and the mounting frame 31 set on the bottom of the outer side of the collection box 33 leave the processing box 11 through the opening on one side of the processing box 11. The two universal wheels 32 installed at the bottom of the mounting frame 31 move on the extension plate 113 to ensure that the collection box 33 storing a large number of special-shaped sheet metal parts 5 is still stably supported after leaving the processing box 11. The staff moves the collection box 33 out of the mounting frame 31 and installs the empty collection box 33 on the mounting frame 31, so as to facilitate the collection of the special-shaped sheet metal parts 5 cut by the laser cutting machine 19.

[0043] Then the industrial robot arm 18 works to adjust the longitudinal position of the laser cutting machine 19. The laser cutting machine 19 moves to the position at the top of the sheet metal plate 4 where there is no cutting hole formed by the special-shaped sheet metal part 5. The telescopic pneumatic cylinder 2 35 works synchronously to move the transmission part 2 34, and the transmission part 2 34 remains at the bottom of the laser cutting machine 19.

[0044] In addition, such as Figure 8 As shown, the two mounting frames 5 310 are both arranged at the bottom of the sheet metal plate 4, and the support roller 1 38 is arranged at the bottom of the sheet metal plate 4.
