Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a pipeline laser cutting machine with a guided material discharge function. Background Art

[0002] The working principle of the pipeline laser cutting machine is mainly based on the high energy density and precise control of the laser beam. Its core component is the laser, which is responsible for generating a high-energy, stable laser beam. After being excited by electrical energy, the gas, solid or semiconductor material inside the laser generates photons and is continuously amplified by the reflector of the resonant cavity, eventually forming a beam of high-energy, high-density laser. The generated laser beam is transmitted to the cutting head through an optical system such as an optical fiber or a lens group. The cutting head focuses the laser beam on a very small spot to increase the energy density of the laser. When the high-energy laser beam is irradiated on the surface of the pipe, the material in the irradiated area quickly melts, vaporizes or reaches the ignition point. At the same time, a high-speed airflow coaxial with the beam (such as nitrogen, oxygen, etc.) blows away the molten material, thereby achieving the cutting of the pipe. The movement trajectory of the laser beam is precisely controlled by a computer, and it can be cut according to the preset graphics.

[0003] At present, when the pipe laser cutting machines on the market are in use, the pipes will be cut and fall off after being extended to a certain length, and the laser cutting machines lack components to collect and arrange them, so the pipes will collide with each other when they fall, causing damage to the surface of the pipes. As a result, the existing pipe laser cutting machines are unable to perform the functions of guiding, collecting and directional arrangement of the pipes when in use. Therefore, a device is needed to improve the above problem. Summary of the invention

[0028] The end of the extension rod 7 away from the rack 10 is connected to the blocking plate 14, the bracket 19 is fixedly installed at the inner bottom end of the laser cutting mechanism 4, the limit slide rod 30 is slidably inserted into the top end of the support frame 32, the rear end of the support frame 32 is connected to the front bottom of the laser cutting mechanism 4, the tooth distribution angle of the second gear 22 is 180°, a through hole is provided at the bottom end of the transfer cavity 15, and the blocking plate 14 is vertically aligned with the through hole, a round hole is provided at the inner bottom end of the guide cavity 18, the photoelectric sensor 13 is electrically connected to the drive motor 23, the blocking plate 14 is slidably sleeved on the guide round rod 21, and the top two sides of the support frame 32 are provided with The card slot, the pulley 33 of the supporting chassis 32 close to the blocking chassis 38 is connected with the fifth gear 40, the fifth gear 40 is meshed with the third gear 37, the transmission ratio of the fifth gear 40 to the third gear 37 is 1:10, the second alignment key 36 and the first alignment key 35 are arranged at an angle of 45° on the opposite end surface, the extended round rod 9 is aligned with the first alignment key 35 and the second alignment key 36, the transfer cavity 15 and the guide cavity 18 are interconnected, the plastic strip 31 is vertically aligned with the belt 34, the third gear 37 and the fourth gear 39 are spaced 1 cm apart, and the first alignment key 35 and the second alignment key 36 are spaced 1 cm apart from the fourth gear 39; A lifting cylinder is installed inside the feeding mechanism 3, and a support frame is installed on the lifting cylinder, so that the pipeline can be placed on the support frame. At the same time, a feeding system is installed inside the laser cutting mechanism 4, and a feeding wheel and a clamping mechanism are installed in the feeding system, so that the feeding wheel can drive the pipeline to move, and the clamping mechanism can limit the pipeline, so that the laser cutting system can cut the pipeline.

[0029] The working principle of embodiment 1 is as follows: when in use, the pipe is transported to the inside of the laser cutting mechanism 4 through the feeding mechanism 3, and the inside of the laser cutting mechanism 4 is provided with a feeding system and a laser cutting system, so that when the laser cutting mechanism 4 is started, it can drive the pipe to move to a specified length and then be cut by the laser cutting system. Subsequently, the guide cavity 18 is vertically aligned with the feeding system, so that when the pipe is cut and falls, it can directly enter the inside of the guide cavity 18. A circular hole is opened in the guide cavity 18 to avoid the accumulation of welding slag in the guide cavity 18. At the same time, the setting of the roller 17 can improve the sliding smoothness of the steel pipe in the guide cavity 18. Subsequently, the transfer cavity 15 is connected with the guide cavity 18, so that the pipe can slide to The interior of the transfer chamber 15, and a through hole is opened through the inner bottom end of the transfer chamber 15, and the blocking plate 14 is located directly below the transfer chamber 15 when it remains in a normal state. When the pipe contacts the blocking plate 14, the photoelectric sensor 13 can be triggered to start the driving motor 23 to drive the second gear 22 to rotate one circle. When the second gear 22 rotates, the outer ring with teeth meshes with the first gear 16, which can drive the first gear 16 and the winding wheel 24 to rotate. When the winding wheel 24 rotates, the blocking plate 14 can be pulled to move to one end away from the transfer chamber 15 through the connecting rope 25. The blocking plate 14 is slidably sleeved on the guide round rod 21, so that the blocking plate 14 can be supported to move in a straight line to prevent the blocking plate 14 from falling off during movement. At the same time, when the blocking plate When the plate 14 is displaced toward the end away from the transfer chamber 15, the extension rod 7 and the rack 10 can be driven to move at the same time. When the rack 10 moves, it can move on the top of the fourth gear 39, so that the third gear 37 can be driven to rotate, and when the third gear 37 rotates, the fifth gear 40 can also be driven to rotate. When the rack 10 completely passes through the top of the fourth gear 39, the third gear 37 can be driven to rotate one circle, and when the third gear 37 rotates one circle, the fifth gear 40 can be driven to rotate one tenth of a circle. The collecting chamber 28 is placed on the top of the supporting frame 32, and the plastic strip 31 is fitted with the belt 34, so that when the belt 34 rotates, the collecting chamber 28 can be driven to move toward the end close to the transfer chamber 15. When the rack 10 completely passes through the fourth gear 39, the belt 34 can be driven to rotate one tenth of a circle. When the top of the transfer chamber 15 is reached, the collecting chamber 28 can drive the gap between the partition frames 29 to move to be vertically aligned with the through hole at the bottom end of the transfer chamber 15, so that the blocking plate 14 is moved out from the bottom end of the transfer chamber 15. At the same time, the collecting chamber 28 can drive the gap between the partition frames 29 to be vertically aligned with the bottom end of the transfer chamber 15, so that the fallen pipe can be received, and the work of guiding the discharge and directional arrangement of the pipe can be completed. At the same time, when the connecting rope 25 pulls the blocking plate 14 to move to the extreme position, it can also drive the extended round rod 9 to contact the surface of the second alignment key 36, so that the extended round rod 9 can drive the rack 10 to tilt upward along the surface of the second alignment key 36 until the blocking plate 14 moves to the extreme position, and the extended round rod 9 can move to the extreme position along the surface of the second alignment key 36.When the second gear 22 is fully reset, the extension rod 9 can be driven to contact the first alignment key 35, so that the extension rod 9 can be rotated downward along the surface of the first alignment key 35 to reset until the rack 10 is disengaged from the second magnetic sheet 11. When the gear 16 is out of contact, the rack 10 will naturally droop until the first magnetic sheet 8 is adsorbed and attached, completing the reset of the rack 10. When the device is in use, a reset spring is symmetrically fixed between the bottom end of the transfer cavity 15 away from the extension frame 20 and the side end of the blocking plate 14 close to the drive motor 23. When the first gear 16 loses its meshing force, the reset spring will drive the blocking plate 14 to move and reset, and the length of the reset spring is greater than the length of the through hole at the bottom end of the transfer cavity 15, so that the interference of the reset spring pipeline can be avoided. When the collection cavity 28 is displaced, the limiting slide bar 30 can be driven to slide in the card slot inside the top of the support frame 32, so that the collection cavity 28 can be ensured to move in a straight line. At the same time, the distance of the fifth gear 40 rotating one tenth of a circle is equal to the gap between the two partition frames 29, so that each time the fifth gear 40 rotates, the gap between the two partition frames 29 can be driven to move to be vertically aligned with the through hole at the bottom end of the transfer cavity 15, completing the work.

[0030] Embodiment 2

[0031] On the basis of Example 1, Figure 8 As shown, the support base 32 also includes a guide inclined plate 41 and an anti-deflection side plate 42 . The guide inclined plate 41 is fixedly installed on the right side of the support base 32 , and the anti-deflection side plate 42 is symmetrically fixedly installed at the front and rear ends of the guide inclined plate 41 .

[0032] When implementing this embodiment, when the collecting chamber 28 moves out from the top of the supporting base frame 32, it can be moved to the top of the guide inclined plate 41, so that the collecting chamber 28 can move downward along the guide inclined plate 41. At the same time, the anti-deflection side plates 42 are located at both ends of the guide inclined plate 41, and the inner side of the anti-deflection side plates 42 is in contact with the side end surface of the collecting chamber 28 close to the limiting slide bar 30, so that the collecting chamber 28 can be ensured to slide on the guide inclined plate 41 in a straight line, avoiding the phenomenon of the collecting chamber 28 tilting and falling during displacement, thereby completing the work.
