Description

Technical Field

[0001] This application relates to the field of laser cutting machine technology, and more specifically, to a laser cutting machine for beveling pipes. Background Technology

[0002] A laser cutting machine is a device that uses a high-energy-density laser beam to cut materials. By focusing the laser beam onto the material, the material is melted or vaporized by high temperature, achieving precise cutting. Laser cutting machines can be used to create bevels at specific angles at the ends of pipes or designated locations.

[0003] In related technologies, to address the problem of complex structures and excessively large sizes in laser head mounting devices for laser cutting machines, patent CN218575271U provides a pipe beveling laser cutting machine. This device, through the linkage of a moving chuck, a front chuck, a drive device, and a beveling swing shaft device, allows the pipe or workpiece to be processed to move along the X-axis and rotate around the X-axis. The laser head can move along the Y and Z axes and rotate around the A-axis, thus generating a composite motion of five axes to achieve three-dimensional beveling. The pipe beveling laser cutting machine has a simple structure for mounting the laser head, effectively reducing the size of the mounting device and machine tool, improving the dynamic response of the laser head, and effectively reducing the failure rate of the machine tool, thereby improving the cutting efficiency and cutting quality of the machine tool.

[0004] Although the existing technical solutions mentioned above can simplify the installation structure and reduce the size of the installation device and machine tool by setting up a drive device and a bevel swing shaft device to connect the laser head, after the laser head cuts the processed tube, the tube is dropped in a free-fall manner. The bevel of the tube is easily damaged by collision, resulting in a decrease in the quality of the processed tube.

[0005] In view of this, we propose a laser cutting machine for pipe beveling. Utility Model Content

[0006] The purpose of this application is to provide a laser cutting machine for pipe beveling, which can effectively solve the problem in the prior art where, after the laser head has cut the processed pipe, the pipe is dropped freely, and the bevel of the pipe is easily damaged by impact, resulting in a decrease in the quality of the processed pipe.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] (1) This application uses a receiving component, which performs beveling and cutting on the pipe by the laser cutting component. The processed pipe falls into the inner side of the groove wheel, and the groove wheel is driven to rotate by external force to transfer the pipe. Finally, the pipe is unloaded by the guide plate.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Reference Figure 1 , Figure 4 and Figure 5 This application discloses a laser cutting machine for pipe beveling, including a cutting table 1, a top plate 11 fixedly disposed on the top of the cutting table 1, a laser cutting component 2 disposed on the bottom of the top plate 11, a receiving component 3 disposed on the bottom of the laser cutting component 2, the receiving component 3 disposed on one side of the cutting table 1, the receiving component 3 includes a grooved wheel 31, the outer side of the grooved wheel 31 is provided with a U-shaped groove 311 arranged in a ring array, the grooved wheel 31 is disposed on the inner side of the outer shell 32, the grooved wheel 31 is driven by an external force to rotate intermittently on the inner side of the outer shell 32, the outer shell 32 is fixedly disposed on one side of the cutting table 1, and a discharge port 33 is opened on one side of the bottom of the outer shell 32, and a guide plate 34 is fixedly disposed on the bottom of the discharge port 33.

[0029] When processing the pipe, the laser cutting component 2 beveles the pipe and then cuts it, so that the cut pipe falls into the inner side of the top U-shaped groove 311. The U-shaped groove 311 is U-shaped to facilitate the laser cutting component 2 to process the pipe inside the top U-shaped groove 311.

[0030] During material feeding, the grooved wheel 31 is driven by external force to rotate inside the outer casing 32, thereby driving the processed pipe to rotate. When it rotates to the discharge port 33, the pipe can be fed along the guide plate 34, avoiding collisions between the pipes.

[0031] Reference Figure 1 , Figure 2 and Figure 3 A fixed base 4 is fixedly installed on the top of the cutting table 1 on one side of the receiving assembly 3. A drive motor B41 is fixedly installed on the outside of the fixed base 4. A gear 42 is fixedly installed at the output end of the drive motor B41. A gear ring 43 is meshed on the outside of the gear 42. The gear ring 43 is rotatably installed on the outside of the fixed base 4. A hydraulic rod 44 is arranged in a ring array on the outside of the gear ring 43. A fixed frame 45 is fixedly installed at the output end of the hydraulic rod 44. A clamping roller 46 is rotatably installed on the inside of the fixed frame 45. A movable seat 5 is slidably installed on the top of the cutting table 1. A drive motor C51 is fixedly installed on the outside of the movable seat 5. A four-jaw chuck 52 is installed at the output end of the drive motor C51. A top plate 11 is installed on the top of the cutting table 1. An electric slider 53 is installed on the outside of the movable seat 5 in cooperation with the top plate 11 to drive the movable seat 5 to slide on the top of the cutting table 1.

[0032] When clamping the pipe, one end of the pipe is clamped by the four-jaw chuck 52, and the other end of the pipe is passed through the toothed ring 43. Several hydraulic rods 44 are activated, which drive the fixed frame 45 to move, thereby causing the clamping roller 46 to clamp the outside of the pipe.

[0033] When beveling and cutting the pipe, the drive motor B41 is started, which drives the gear 42 to rotate, thereby driving the gear ring 43 to rotate. The drive motor C51 is started, which drives the four-jaw chuck 52 to rotate synchronously with the gear ring 43, thereby driving the pipe to rotate. The number of teeth on the outer side of the gear 42 is one-third the number of teeth on the outer side of the gear ring 43. The output end of the drive motor B41 rotates three times, and the output end of the drive motor C51 can rotate one time, so that the four-jaw chuck 52 and the gear ring 43 rotate synchronously. While the pipe is rotating, the electric slider 53 can slide on the top of the slide rail 12, thereby driving the moving seat 5 to slide on the top of the cutting table 1, driving the pipe to move horizontally, and the pipe is processed by the laser cutting component 2.

[0034] Among them, the four-jaw chuck 52 and the electric slider 53 are both existing technology devices. The four-jaw chuck 52 is a Sanou K12 type chuck, and the electric slider 53 is an MRA slider.

[0035] Reference Figure 4 and Figure 5 A connecting plate 35 is detachably provided on the outer side of the grooved wheel 31. The connecting plate 35 is fixedly provided on the output end of the drive motor A36. The drive motor A36 is fixedly provided on the outer side of the housing 32. A cutting opening 321 is provided on the top of the housing 32. Several waste outlets 322 are provided on the bottom of the housing 32.

[0036] During material feeding, the connecting plate 35 is driven to rotate by the drive motor A36, which in turn drives the grooved wheel 31 to rotate. The grooved wheel 31 then carries the processed pipe for transfer. When the pipe is transported to the bottom of the outer shell 32, the impurities generated during processing fall through the waste port 322. The rotation continues, which in turn drives the pipe to feed.

[0037] In summary, the laser cutting machine for pipe beveling disclosed in this application operates by starting the drive motor B41, which drives the gear 42 to rotate, thereby rotating the gear ring 43. By starting the drive motor C51, the four-jaw chuck 52 rotates synchronously with the gear ring 43, thereby rotating the pipe. At the same time, the electric slider 53 can slide on the top of the slide rail 12, thereby driving the moving seat 5 to slide on the top of the cutting table 1, causing the pipe to move horizontally. The laser cutting assembly 2 processes the pipe. After beveling the pipe, the laser cutting assembly 2 cuts the pipe, causing the cut pipe to fall into the U-shaped groove 311 at the top. The U-shaped groove 311 is U-shaped to facilitate the laser cutting assembly 2 to process the pipe inside the U-shaped groove 311 at the top.

[0038] During material feeding, the connecting plate 35 is driven to rotate by the drive motor A36, which in turn drives the grooved wheel 31 to rotate inside the outer casing 32, thereby driving the processed pipe to rotate. When the pipe is transported to the bottom of the outer casing 32, the impurities generated during processing fall through the waste port 322 and continue to rotate to the discharge port 33. The pipe can be fed along the guide plate 34 to avoid the pipe from being bumped.
