Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of laser cutting, and in particular to a laser cutting machine with automatic loading and a using method thereof. Background Art
[0002] Laser cutting is a common thermal cutting process. The laser cutting uses a laser beam with a high power density to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and holes are formed by evaporation. As the beam moves relative to the material, the holes continuously form a very narrow slit, thereby completing the cutting of the material.
[0003] In the prior art, when using a laser cutting device to perform segmented cutting on a pipe fitting, due to the long size of the pipe fitting, the laser cutting machine usually holds the end of the pipe fitting for the loading operation. Since only one end of the pipe fitting is clamped, in the initial cutting stage, for a long and thin-wall pipe fitting, when rotating the pipe fitting for cutting, it is easy for the unclamped end of the pipe fitting to shake and deviate from the axis. The shaking will cause the pipe fitting to deviate from the predetermined cutting path during the cutting process, resulting in a large deviation in the cutting size and being unable to meet the high-precision processing requirements. In addition, it will also cause the width of the cut to be uneven, resulting in a serrated or wavy cut, and deteriorating the cut quality. Summary of the Invention

[0016] Preferably, the pipe feeding mechanism includes a top plate fixedly installed on the bracket, reversing grooves are formed on both sides of the top plate, an electric push rod I fixedly connected to the bracket is arranged below the reversing grooves, a lifting plate is fixedly connected to the output shaft of the electric push rod I, an electric push rod II is fixedly connected to the bottom of the top plate, an outer sleeve is movably sleeved on the output shaft of the electric push rod, an inner sleeve is movably sleeved inside the outer sleeve, an automatic clamp is fixedly connected to the bottom of the inner sleeve, a guide plate is fixedly connected to the top of the outer sleeve, and the guide plate is slidably installed in the reversing groove.
[0017] Preferably, the chuck, the faceless wheel I and the faceless wheel II are arranged in sequence from bottom to top, and the feeding operations of the pipe fittings are respectively and sequentially carried out under the drive of the pulley group.
[0018] Preferably, a method for using an automatic feeding laser cutting machine includes the following steps:
[0019] S1: At the start of the operation, pipe fittings are batch-fed into the lower hopper, and at the same time, the drive motor is started. A pipe fitting at the lowest position falls from the lower hopper onto the pipe pushing table. The drive motor drives the faceless wheel I, the faceless wheel II and the chuck to rotate through the pulley group. The chuck first snaps into the bayonet on the rotating frame and drives the gear disk to rotate. The rotation of the gear disk drives the gear I to rotate one circle. Then the chuck disengages from the bayonet. The rotation of the gear I drives the cam to rotate synchronously, so that the cam drives the mounting rod to move through the guide groove and pulls the mounting rod outwards. The mounting rod drives the pushing plate to slide towards the middle of the machine table. During the process, the L-shaped plate pushes the pipe fitting on the pipe pushing table horizontally. During the pushing process, the long end of the L-shaped plate contacts the pushing plate. During the half-circle rotation of the cam, the pressing block presses the bottom of the rack III downwards, so that the rack III drives the gear III to rotate, and the convex head disk rotates synchronously, pushing the two clamping arms at the top and bottom apart synchronously, so that the distance between the two clamping arms is enlarged. After the pipe fitting approaches, the two ends of the pipe fitting respectively contact the clamping arms at the lower position. At this time, the half-circle rotation of the cam is completed, and it continues to rotate half a circle and return under the drive of the gear I. The pressing block disconnects from the rack III, and the two clamping arms automatically return to clamp the pipe fitting. During the return process of the pushing plate, the short end of the L-shaped plate contacts the automatically falling pipe fitting and causes the L-shaped plate to flip by a certain angle. Then, under the action of the gravity of its long end, it automatically falls.
[0020] S2: After the two ends of the pipe are clamped, the laser cutting head starts to cut the central symmetrical point of the pipe into sections. At the same time, the notch wheel 2 on the top of the clamp engages with the gear 2, driving the gear 2 to rotate in the opposite direction. The swing arm pulls the slide bar out from the support frame on one side, driving the rack 2 to move synchronously. During the pulling process of the rack 2, the gear 4 is driven to rotate. The gear 4 clamps the paddle through the clamping tooth mouth, so that the gear 4 is docked with the disc, and the shaft rotates synchronously. When the shaft rotates, it drives the mounting plate clamped with the pipe to rotate one circle, which is convenient for rotating the pipe during the cutting process. After one circle, the pipe is divided into two sections, and the middle support plate supports the disconnected part of the pipe.
[0021] S3: After rotating one circle, the second notch wheel is disconnected from the second gear, and then the first notch wheel at the bottom is engaged with the rack, so that the rack moves horizontally and is pulled out, and drives the wedge frame to move synchronously. When the wedge frame moves, it abuts against the end of the slide bar and pulls the slide bar outward. The slide bar pulls the push tube toward the inside of the mounting platform, so that the push tube drives the rotating rod to be retracted into the inside of the mounting platform. At this time, the cylinder is in a retracted state and there is no obstruction in the mounting platform. When the rotating rod touches the bottom, the rotating rod stops moving horizontally, and the push tube continues to move, so that the slider moves in the spiral groove, and through the spiral groove, drives the rotating rod to rotate ninety degrees along the trajectory of the spiral groove, and drives the rotating mechanism to rotate the segmented pipe fitting ninety degrees, so that the pipe fitting is erected, and then the first notch wheel is disconnected from the rack;
[0022] S4: After the pipe is erected, it moves into the clamping range of the automatic fixture, and the automatic fixture clamps the pipe. At the same time, the electric push rod 1 drives the lifting plate to move upward, so that the automatic fixture drives the pipe to be lifted up, and the bottom of the pipe is separated from between the clamping arms. The cylinder outputs to the inside of the mounting table to return the vertical pipe mechanism. When the pipe rises, the inner sleeve is retracted into the inner part of the outer sleeve. The electric push rod 2 is started and outputs forward so that the outer sleeve drives the pipe to approach the top of the laser cutting head 2. When the outer sleeve drives the guide plate to move synchronously, the top of the guide plate passes through the reversing groove, so that its head and tail positions are reversed, and the opening direction of the automatic fixture is changed. Then the pipe is turned to the top of the laser cutting head 2, and the automatic fixture is opened for secondary loading of the pipe. The pipe enters the laser cutting head 2 for re-segmented cutting, and the electric push rod 2 is retracted to return the automatic fixture to its position again.
[0023] Compared with the prior art, the present invention has the following beneficial effects:
[0024] 1. In the present invention, through the arranged pipe-pulling mechanism, when the driving motor operates, the pulley group drives the chuck to be clamped into the bayonet, causing the toothed disc to rotate and driving the first gear to rotate one full circle, pulling the pushing frame outwards and then pushing it back. During the movement of the pushing frame, a pipe fitting is pulled out by the L-shaped plate, and the pressing head causes the clamping arms to be opened, for automatic feeding and clamping. By clamping both ends of the pipe fitting simultaneously, the initial cutting of the pipe fitting is carried out, preventing cutting shaking caused by the excessive length of the pipe fitting and improving the cutting precision.
[0025] 2. In the present invention, through the arranged second missing-face wheel, after the pipe fitting is clamped, the second missing-face wheel drives the second gear and the swing arm to rotate, pulling the second rack outwards. During this process, the two clamping arms are driven to rotate. After the pipe fitting is fed and during the initial cutting process, the pipe fitting is rotated to facilitate cutting.
[0026] 3. In the present invention, through the arranged riser pipe mechanism, when the second missing-face wheel disengages from the second gear and the initial cutting is completed, the first missing-face wheel engages with the first rack, pulling the pushing pipe towards the inside of the installation table. During this process, the pipe fitting is driven to move horizontally. After the rotating rod touches the bottom, the rotating rod rotates, causing the pipe fitting to swing upwards to a vertical state, facilitating the vertical cutting of the pipe fitting to reduce the cutting size deviation and improve the incision precision.
[0027] 4. In the present invention, through the arranged pipe feeding mechanism, after clamping the vertical pipe fitting, the pipe fitting is lifted upwards and disengaged from between the clamping arms. During the conveying process, the positions of the pipe fitting and the automatic fixture are reversed, facilitating the feeding operation towards the second laser cutting head.

[0062] The usage method and advantages of the present invention: For the laser cutting machine with automatic feeding and its usage method, the working process is as follows:
[0063] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 shown:
[0064] S1: At the start of the operation, a batch of pipe fittings is put into the lower hopper 502. Meanwhile, the drive motor 3 is started. A pipe fitting at the lowest position falls from the lower hopper 502 onto the pipe-pushing table 505. The drive motor 3 drives the one-sided wheel 401, the two-sided wheel 402, and the chuck 414 to rotate through the pulley group 403. The chuck 414 is first inserted into the bayonet 406 on the rotary frame 405 and drives the gear disk 404 to rotate. The rotation of the gear disk 404 drives the first gear 407 to rotate one circle. Subsequently, the chuck 414 disengages from the bayonet 406. The rotation of the first gear 407 drives the cam 408 to rotate synchronously, causing the cam 408 to drive the mounting rod 504 to move through the guide groove 409, pulling the mounting rod 504 outwards. The mounting rod 504 drives the pushing plate to slide towards the middle of the machine table 1. During this process, the L-shaped plate 506 pushes the pipe fitting on the pipe-pushing table 505 horizontally. During the pushing process, the long end of the L-shaped plate 506 contacts the pushing plate 503. During the half-circle rotation of the cam 408, the pressing block 509 presses down the bottom of the third rack 608, causing the third rack 608 to drive the third gear 607 to rotate, and the convex head disk 606 rotates synchronously, pushing open the two clamping arms 605 at the top and bottom simultaneously, increasing the distance between the two clamping arms 605. After the pipe fitting approaches, the two ends of the pipe fitting respectively contact the clamping arms 605 at the lower position. At this time, the half-circle rotation of the cam 408 is completed, and it continues to rotate half a circle and return under the drive of the first gear 407. The pressing block 509 disconnects from the third rack 608, and the two clamping arms 605 automatically return to clamp the pipe fitting. During the return process of the pushing plate 503, the short end of the L-shaped plate 506 contacts the automatically falling pipe fitting and causes the L-shaped plate 506 to flip by a certain angle. Subsequently, under the action of the gravity of its long end, it automatically falls;
[0065] S2: After the two ends of the pipe fitting are clamped, the first laser cutting head 9 starts to cut and segment the central symmetry point of the pipe fitting. Meanwhile, the two-sided wheel 402 at the top of the chuck 414 meshes with the second gear 410, driving the second gear 410 to rotate in the reverse direction. The swing arm 411 pulls the sliding rod 601 outwards from one side of the support frame 507, driving the second rack 602 to move synchronously. During the pulling process of the second rack 602, it drives the fourth gear 613 to rotate. The fourth gear 613 catches the dial 611 through the tooth engagement port 614, docking the fourth gear 613 with the disk 610 and causing the rotating shaft 603 to rotate synchronously. When the rotating shaft 603 rotates, it drives the mounting plate 604 holding the pipe fitting to rotate one week, facilitating the rotation of the pipe fitting during the cutting process. After rotating one week, the pipe fitting is divided into two sections, and the middle support plate 508 supports the disconnection point of the pipe fitting;
[0066] S3: After rotating one full circle, the incomplete-face wheel two 402 disengages from the gear two 410. Subsequently, the incomplete-face wheel one 401 at its bottom engages with the rack one 412, causing the rack one 412 to move horizontally and be pulled out, and driving the wedge-shaped frame 413 to move synchronously. When the wedge-shaped frame 413 moves, it abuts against the end of the slide bar 601 and pulls the slide bar 601 outwards. The slide bar 601 pulls the push pipe 703 towards the inside of the mounting table 701, causing the push pipe to drive the rotating rod 704 to retract into the mounting table 701. At this time, the air cylinder 709 is in the retracted state and there is no obstruction inside the mounting table 701. When the rotating rod 704 touches the bottom, the rotating rod 704 stops translating, and the push pipe 703 continues to move, causing the slider 705 to move within the spiral groove 706. Through the spiral groove 706, the rotating rod 704 is driven to rotate ninety degrees along the trajectory of the spiral groove 706, driving the rotating mechanism 6 to rotate the segmented pipe fitting ninety degrees, making the pipe fitting stand upright. Subsequently, the incomplete-face wheel one 401 disengages from the rack one 412;
[0067] S4: After the pipe fitting stands upright, it moves into the clamping range of the automatic fixture 808. The automatic fixture 808 clamps the pipe fitting. At the same time, the electric push rod one 803 drives the lifting plate 804 to move upwards, causing the automatic fixture 808 to drive the pipe fitting to be lifted upwards, and the bottom of the pipe fitting disengages from between the clamping arms 605. The air cylinder 709 outputs towards the inside of the mounting table 701, causing the vertical pipe mechanism 7 to return to its original position. When the pipe fitting rises, the inner sleeve 807 is retracted into the outer sleeve 806. The electric push rod two 805 is activated and outputs forward, causing the outer sleeve 806 to drive the pipe fitting towards the top of the laser cutting head two 10. When the outer sleeve 806 drives the guide plate 809 to move synchronously, the top of the guide plate 809 passes through the reversing groove 802, causing its head and tail positions to be reversed, and changing the opening direction of the automatic fixture 808. Subsequently, the pipe fitting is rotated to the top of the laser cutting head two 10, and the automatic fixture 808 opens for secondary loading of the pipe fitting. The pipe fitting enters the laser cutting head two 10 for re-segmentation cutting, and the electric push rod two 805 retracts, causing the automatic fixture 808 to return to its original position again.

The method for using the automatic loading laser cutting machine according to claim 1, characterized in that: The steps include: S1: When the operation starts, pipes are put into the lower pipe bucket (502) in batches, and the drive motor (3) is started at the same time. The pipe at the lowest position falls from the lower pipe bucket (502) to the pipe-pickup platform (505). The drive motor (3) drives the first notch wheel (401), the second notch wheel (402) and the clamping head (414) to rotate through the pulley group (403). The first position of the clamping head (414) is clamped into the clamping port (406) on the rotating frame (405), and drives the toothed disc (404) to rotate. The gear plate (404) rotates to drive the gear 1 (407) to rotate one circle, and then the clamp (414) is disengaged from the clamp (406). The gear 1 (407) rotates to drive the cam (408) to rotate synchronously, so that the cam (408) drives the installation rod (504) to move through the guide groove (409), and the installation rod (504) is pulled outward. The installation rod (504) drives the push plate to slide toward the middle of the machine platform (1). During the process, the L-shaped plate (506) pushes the pipe fitting water on the pipe-pulling platform (505) to move. The L-shaped plate (506) moves horizontally, and the long end of the L-shaped plate (506) contacts the pushing plate (503) during the pushing process. When the cam (408) rotates half a circle, the pressing block (509) presses the bottom of the rack three (608) downward, so that the rack three (608) drives the gear three (607) to rotate, and the convex head plate (606) rotates synchronously, and the two clamping arms (605) at the top and bottom are synchronously pushed apart, so that the distance between the two clamping arms (605) is expanded. After the pipe fittings are close, the two ends of the pipe fittings are respectively in contact with the The clamping arm (605) at the lower position, at this time, the cam (408) completes half a circle of rotation, and continues to rotate half a circle to return to its original position under the drive of the gear 1 (407), the pressing block (509) is disconnected from the rack 3 (608), and the two clamping arms (605) automatically return to their original position to clamp the pipe fittings. During the return process of the push plate (503), the short end of the L-shaped plate (506) contacts the automatically falling pipe fittings, and causes the L-shaped plate (506) to flip to a certain angle, and then automatically falls under the gravity of its long end; S2: After the two ends of the pipe are clamped, the laser cutting head 1 (9) starts to cut the central symmetrical point of the pipe into sections. At the same time, the notched wheel 2 (402) on the top of the clamp (414) meshes with the gear 2 (410), driving the gear 2 (410) to rotate in the opposite direction. The swing arm (411) pulls the slide bar (601) out from the support frame (507) on one side, driving the rack 2 (602) to move synchronously. During the pulling process, the rack 2 (602) drives The gear 4 (613) rotates, and the gear 4 (613) clamps the paddle (611) through the clamping tooth opening (614), so that the gear 4 (613) is docked with the disc (610), so that the rotating shaft (603) rotates synchronously. When the rotating shaft (603) rotates, it drives the mounting plate (604) clamped with the pipe to rotate one circle, so as to facilitate the rotation of the pipe during the cutting process. After one circle of rotation, the pipe is divided into two sections, and the middle support plate (508) supports the broken part of the pipe. S3: After one rotation, the faceless wheel 2 (402) is disconnected from the gear 2 (410), and then the faceless wheel 1 (401) at the bottom thereof is engaged with the rack 1 (412), so that the rack 1 (412) moves horizontally and is pulled out, and drives the wedge frame (413) to move synchronously. When the wedge frame (413) moves, it abuts against the end of the slide bar (601) and pulls the slide bar (601) outward. The slide bar (601) pulls the push tube (703) toward the inside of the mounting platform (701), so that the push tube drives the rotating rod (704) toward the mounting platform (701). The cylinder (709) is retracted into the interior of the mounting platform (701). At this time, the cylinder (709) is in a retracted state and there is no obstruction in the mounting platform (701). When the rotating rod (704) touches the bottom, the rotating rod (704) stops translating, and the push tube (703) continues to move, so that the slider (705) moves in the spiral groove (706). Through the spiral groove (706), the rotating rod (704) is driven to rotate ninety degrees along the trajectory of the spiral groove (706), and the rotating mechanism (6) is driven to rotate the segmented pipe by ninety degrees, so that the pipe is erected, and then the faceless wheel (401) is disconnected from the rack (412); S4: After the pipe is erected, it moves to the clamping range of the automatic clamp (808), and the automatic clamp (808) clamps the pipe. At the same time, the electric push rod 1 (803) drives the lifting plate (804) to move upward, so that the automatic clamp (808) drives the pipe to be lifted upward, and the bottom of the pipe is separated from between the clamp arms (605). The cylinder (709) outputs to the inside of the mounting platform (701) to return the vertical pipe mechanism (7). When the pipe rises, the inner sleeve (807) is received in the inner part of the outer sleeve (806), and the electric push rod 2 (805) is started and outputs forward to make the outer sleeve ( 806) drives the pipe fitting to approach the top of the second laser cutting head (10). When the outer sleeve (806) drives the guide plate (809) to move synchronously, the top of the guide plate (809) passes through the reversing groove (802), so that its head and tail positions are reversed, and the opening direction of the automatic clamp (808) is changed. Then the pipe fitting is turned to the top of the second laser cutting head (10), and the automatic clamp (808) is opened for secondary loading of the pipe fitting. The pipe fitting enters the second laser cutting head (10) for re-segmented cutting, and the second electric push rod (805) is retracted to make the automatic clamp (808) return to its position again.
