Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, specifically a continuous steel pipe laser cutting device. Background Technology

[0002] Laser cutting of steel pipes utilizes a high-energy-density laser beam focused on the surface of the steel pipe, causing the steel material to melt or vaporize rapidly. The laser beam energy is highly concentrated, causing the local temperature of the material to rise sharply in a very short time. At the same time, the molten or vaporized material is blown away by an auxiliary gas (such as oxygen or nitrogen). Generally, the steel pipe is bent before cutting. Curved steel pipes require special clamps for cutting, and continuous feeding and cutting cannot be performed, resulting in low processing efficiency.

[0003] Chinese patent CN220006414U discloses a laser cutting device for steel pipes, comprising a laser cutting device body, a base plate, a support plate welded to the base plate, an opening in the support plate, a fixed column movably mounted inside the opening, a scale line fixed on the fixed column, a fixed seat welded to the base plate, a fixed plate welded to one side of the fixed seat, a groove in the fixed plate, a threaded rod rotatably mounted inside the groove, a slider movably mounted on the threaded rod, a laser emitter fixedly mounted at the bottom of the slider, a support base welded to the base plate, an opening in the support base, a limit component movably mounted inside the opening, a lifting mechanism fixedly mounted at the top of the support base, the lifting mechanism cooperating with the limit component, by inserting the fixed column into the hollow part of the steel pipe to collect the cut steel pipe, by moving the limit component up and down, and by the roller moving to both sides through the support mechanism to clamp and fix different steel pipes.

[0004] However, the technical solution of this patent has the following problems:

[0005] This patent involves inserting a fixing column into the hollow part of a steel pipe to collect the cut steel pipe. The limiting component moves up and down, while the roller moves to both sides through the support mechanism to clamp and fix different steel pipes. However, it cannot automatically separate waste material while feeding and cannot perform continuous conveying and cutting.

[0006] Therefore, those skilled in the art have provided a continuous steel pipe laser cutting device to solve the above problems. Utility Model Content

This is beneficial for continuous feeding and automatic separation of waste material.

[0018] 2. The auxiliary conveying device clamps the left side of the steel pipe for auxiliary conveying. The first linear module moves to the right, driving the auxiliary conveying device to move to the right. It adapts to the minimum length after cutting. In conjunction with the steel pipe rotating device, it clamps the right side of the steel pipe. This allows the distance between the auxiliary conveying device and the steel pipe rotating device to adapt to the actual length of the steel pipe during cutting. By moving the output end of the second four-jaw self-centering chuck of the auxiliary conveying device towards the steel pipe, the raising block and guide wheel at the output end of the second four-jaw self-centering chuck move towards the steel pipe. The guide wheel clamps the steel pipe, and the output shaft of the reduction motor rotates, driving the guide wheel to rotate. The rotation of the guide wheel drives the steel pipe to move to the right, which is beneficial for continuous conveying and cutting of the steel pipe. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0027] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A continuous steel pipe laser cutting device includes a frame 1, a vertical support 2 fixedly installed on the middle side of the frame 1, a steel pipe rotating device 3 for clamping and rotating the steel pipe installed on the middle side of the vertical support 2, a second linear module 4 fixedly installed on the upper surface of the upper side of the vertical support 2, a cutting head 5 fixedly installed at the output end of the second linear module 4, the cutting head 5 being a laser cutting machine cutting head, a waste frame 6 fixedly installed on the right side of the frame 1, the waste frame 6 being located on the lower right side of the vertical support 2, and a feeding device 7 installed on the rear side of the frame 1, the feeding device 7 including: a moving rotating component and a clamping component, the moving rotating component being installed on the rear side of the frame 1, and the clamping component being installed on the upper side of the moving rotating component.

[0028] The steel pipe rotating device 3 clamps the steel pipe and rotates it according to a preset time. The output end of the second linear module 4 moves back and forth, driving the cutting head 5 to move back and forth. The steel pipe is cut in conjunction with the rotation of the steel pipe. The unloading device 7 is used to unload the cut steel pipe. The clamping component of the unloading device 7 clamps the cut steel pipe. The moving and rotating component of the unloading device 7 drives the clamped cut steel pipe to move to the right and rotates at the same time, causing the waste material inside the cut steel pipe to fall from the steel pipe into the waste frame 6. The cut steel pipe continues to move to the right for unloading.

[0029] The moving and rotating assembly includes: an irregular frame 71, a rack 72, a sliding block 73, a third gear 74, and a drive assembly. The irregular frame 71 is fixedly installed on the rear side of the frame 1, and the rack 72 is fixedly installed inside the irregular frame 71. The front and rear side walls of the irregular frame 71 are provided with strip-shaped slots 711, and a sliding block 73 is slidably connected to each strip-shaped slot 711. The third gear 74 is rotatably connected between two sliding blocks 73 through a rotating shaft. The drive assembly is installed on the rear side wall of the irregular frame 71, and the third gear 74 and the rack 72 mesh with each other.

[0030] The drive component of the rotating component drives the sliding block 73 to move to the right. The movement of the sliding block 73 to the right drives the third gear 74 to move to the right. The movement of the third gear 74 to the right causes the third gear 74 to move to the right on the rack 72, and the third gear 74 will also rotate on its own axis.

[0031] The drive assembly includes a cylinder 75 and a rotating plate 76. The cylinder 75 is fixedly installed on the rear side wall of the irregular frame 71. The output end of the cylinder 75 is fixedly connected to the rear side of the sliding block 73 on the strip slot 711 on the rear side wall of the irregular frame 71 via a bracket. The rotating plate 76 is fixedly installed on the front side of the shaft of the third gear 74.

[0032] The shortening of the output end of the cylinder 75 of the drive assembly causes the sliding block 73 to move to the right. The movement of the sliding block 73 to the right causes the third gear 74 to move to the right. The movement of the third gear 74 to the right causes the third gear 74 to move to the right on the rack 72, and the third gear 74 will also rotate. The movement and rotation of the third gear 74 to the right causes the rotating plate 76 to move to the right and rotate at the same time.

[0033] The clamping assembly includes: a third linear module 77, electric grippers 78, an extension plate 79, and anti-slip pads 710. The third linear module 77 is fixedly installed on the front side wall of the rotating plate 76. Multiple electric grippers 78 are fixedly installed on the output end of the third linear module 77. The extension plate 79 is fixedly installed on the output end of the electric grippers 78. Multiple anti-slip pads 710 are fixedly installed on each extension plate 79.

[0034] The electric gripper 78 of the clamping assembly starts, driving the extension plate 79 and the anti-slip pad 710 to move towards the steel pipe, clamping the steel pipe. The rotating plate 76 moves to the right and rotates at the same time, driving the third linear module 77 of the clamping assembly to move to the right and rotate at the same time. At the same time, the output end of the third linear module 77 moves upward, driving the electric gripper 78 and the cut steel pipe to move upward. The upward movement distance of the output end of the third linear module 77 is adjusted according to the size of the cut steel pipe to avoid the cut steel pipe hitting the frame 1, which is conducive to continuous feeding and automatic separation of waste.

[0035] Example 2: In some embodiments, such as Figures 1-5 In a preferred embodiment of this utility model, the steel pipe rotating device 3 includes: a first four-jaw self-centering chuck 31, a support block 32, an auxiliary wheel 33, a first gear 34, a servo motor 35, and a second gear 36. The first four-jaw self-centering chuck 31 is rotatably connected to the middle side of the vertical support 2. The support block 32 is fixedly installed at the output end of the first four-jaw self-centering chuck 31. Each support block 32 is rotatably connected to an auxiliary wheel 33 at one end near the center of the first four-jaw self-centering chuck 31 via a rotating shaft. The first gear 34 is fixedly installed on the left side of the first four-jaw self-centering chuck 31. The servo motor 35 is fixedly installed on the left side of the vertical support 2 via a servo motor bracket. The second gear 36 is fixedly installed on the output shaft of the servo motor 35. The second gear 36 and the first gear 34 mesh with each other.

[0036] The steel pipe rotating device 3 clamps the right side of the steel pipe, and moves the output end of the first four-jaw self-centering chuck 31 of the steel pipe rotating device 3 toward the steel pipe, so that the support block 32 and auxiliary wheel 33 at the output end of the first four-jaw self-centering chuck 31 move toward the steel pipe. The auxiliary wheel 33 clamps the steel pipe, and at the same time, under the action of the auxiliary wheel 33, the steel pipe can move left and right while being clamped.

[0037] The servo motor 35 output shaft rotates, driving the second gear 36 to rotate. The second gear 36 rotates, driving the first gear 34 to rotate. The first gear 34 rotates, driving the first four-jaw self-centering chuck 31. The first four-jaw self-centering chuck 31 rotates, driving the clamped steel pipe to rotate. This, in conjunction with the second linear module 4 and its output cutting head 5, cuts the clamped steel pipe.

[0038] A feeding frame 8 is fixedly installed on the right side of the frame 1, and the feeding frame 8 is located to the right of the waste frame 6.

[0039] After cutting, the steel pipe moves to the right under the action of the feeding device 7 and moves to the position of the waste box 6. The electric gripper 78 of the clamping component of the feeding device 7 releases the cut steel pipe, so that the cut steel pipe falls into the waste box 6, which is conducive to automatic feeding.

[0040] A first linear module 9 is fixedly installed on the left side of the frame 1, and an auxiliary conveying device 10 is installed at the output end of the first linear module 9.

[0041] The auxiliary conveying device 10 clamps the left side of the steel pipe for auxiliary conveying. The first linear module 9 moves to the right, driving the auxiliary conveying device 10 to move to the right. It adapts to the minimum length after cutting and works with the steel pipe rotating device 3 to clamp the right side of the steel pipe. This allows the distance between the auxiliary conveying device 10 and the steel pipe rotating device 3 to adapt to the actual length of the steel pipe during cutting.

[0042] The auxiliary conveying device 10 includes: a second four-jaw self-centering chuck 101, a heightening block 102, a guide wheel 103, and a reduction motor 104. The second four-jaw self-centering chuck 101 is rotatably connected to the output end of the first linear module 9 via a bracket. The heightening block 102 is fixedly installed on the output end of the second four-jaw self-centering chuck 101. Each heightening block 102 has a guide wheel 103 rotatably connected to one end of the heightening block 102 near the center of the second four-jaw self-centering chuck 101 via a rotating shaft. Two reduction motors 104 are fixedly installed on two symmetrical heightening blocks 102. The output shaft of the reduction motor 104 is fixedly connected to the rotating shaft of the guide wheel 103 of the heightening block 102 where the reduction motor 104 is located via a coupling.

[0043] The output end of the second four-jaw self-centering chuck 101 of the auxiliary conveying device 10 is moved toward the steel pipe, so that the raising block 102 and guide wheel 103 at the output end of the second four-jaw self-centering chuck 101 move toward the steel pipe. The guide wheel 103 clamps the steel pipe, and the output shaft of the reduction motor 104 rotates to drive the guide wheel 103 to rotate. The rotation of the guide wheel 103 drives the steel pipe to move to the right, which is beneficial for continuous conveying and cutting of the steel pipe.
