Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser cutting equipment, in particular to a multi-angle cutting laser pipe cutting machine. BACKGROUND

[0002] Laser processing technology is a new cutting technology that uses the characteristics of laser beam and material interaction to cut, punch, micro-process and other materials. Laser processing technology has the characteristics of fast, no extrusion, less burr, etc., and therefore has been more and more widely used.

[0003] The focusing mirror of the existing laser pipe cutting machine is adjusted manually or by a single drive adjustment mode. Although some devices have automatic adjustment function, the adjustment mechanism cannot be well buffered, and overshoot is easy to occur when the lens barrel moves due to inertia. Moreover, the stability of the cooling channel cannot be ensured synchronously during the adjustment process, which further affects the adjustment accuracy due to temperature fluctuations of the focusing mirror. It is difficult to adapt to the continuous processing needs of multiple specifications of pipe materials. In addition, during the laser cutting process, the focusing mirror continuously absorbs laser energy and pipe reflected heat. If the heat is not dissipated in time, thermal deformation will occur. The cooling system of the existing device is mostly designed with fixed flow channels. When the focusing mirror moves with the adjustment mechanism, the cooling pipeline is easy to twist or be partially blocked, resulting in interruption of cooling liquid delivery or uneven flow. The local temperature of the focusing mirror is too high, which not only shortens the service life of the focusing mirror, but also causes the laser focal point to drift due to thermal deformation of the lens, affecting the cutting quality and increasing the equipment maintenance cost and downtime frequency. How to invent a multi-angle cutting laser pipe cutting machine to solve these problems has become a problem that needs to be solved by technical personnel in the field. SUMMARY

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Reference Figures 1-12 A multi-angle laser tube cutting machine includes a processing module 2, with a feeding module 1 at one end and a discharging module 3 at the other end. It also includes: Cutting component 4 is connected to processing module 2 and is used to cut pipes.

[0022] Furthermore, the cutting assembly 4 includes a mounting base 41, which is detachably connected to the processing module 2. The mounting base 41 has an annular cavity 411 inside, and a partition 412 is fixedly connected to the inner wall of the cavity 411. There are two partitions 412, which are rotationally symmetrical about the central axis of the cavity 411. The mounting base 41 is connected to an inlet pipe and an outlet pipe. A cylinder 8 is fixedly connected to the inner wall of the mounting base 41. A collimating lens 6 and a laser emitter 7 are fixedly connected to the inner wall of the mounting base 41, with the laser emitter 7 located above the collimating lens 6.

[0023] It should be noted that: The feeding module 1, as the starting point of the material conveying of the equipment, mainly undertakes the functions of automated conveying and preliminary positioning of the pipe. During actual processing, the feeding module 1 can adaptively adjust the conveying speed and clamping force according to the specifications of the pipe (such as diameter and length) to ensure that the pipe remains stable during the conveying process and avoids subsequent processing deviations due to shaking. After the pipe is accurately conveyed into the processing module 2, the processing module 2 will firmly fix the pipe through the built-in clamping structure (such as adjustable chuck and positioning pin). This fixing process can adjust the clamping pressure according to the material characteristics of the pipe (such as the rigidity of metal pipes) to ensure that the pipe does not shift during cutting and to avoid deformation of the pipe due to excessive clamping. After the pipe is fixed, the cutting assembly 4 is activated and enters the working state. The laser emitter 7, as the core source of cutting energy, continuously emits a high-energy laser beam. This laser beam is first calibrated and shaped by the collimating lens 6. The collimating lens 6 can adjust the diverging laser beam into a beam with extremely high parallelism, ensuring that there is no significant loss of laser energy during transmission, while ensuring the accuracy of subsequent focusing. The collimated laser beam continues to be transmitted to the focusing lens 5. The focusing lens 5 focuses the parallel laser beam to a point through optical refraction, forming a laser focus with extremely high energy density. When this focus acts on the surface of the pipe, it can quickly melt, vaporize or ablate the pipe, thereby completing the cutting operation. During the laser cutting process, the focusing lens 5, as a key component for energy focusing, will increase in temperature due to continuous absorption of laser energy and heat reflected from the pipe. If the temperature of the focusing lens 5 is too high, it will not only cause thermal deformation of the lens, affecting the laser focusing accuracy, but may also shorten the lens life and increase equipment maintenance costs. In addition, the equipment is designed with a targeted cooling system: coolant is delivered to the annular cavity 411 inside the mounting base 41 through an external liquid supply device via a water inlet pipe. Two baffles 412 inside the cavity 411 are symmetrically distributed around the central axis, which can guide and divert the flow path of the coolant, preventing the coolant from stagnating in the cavity 411. Under the obstruction and guidance of the baffles 412, the coolant will flow in a direction to one of the telescopic pipes 477, and enter the lens barrel 471 through the telescopic pipe 477. The coolant entering the lens barrel 471 will flow around the outer periphery of the focusing lens 5, and continuously remove the heat generated by the focusing lens 5 through heat conduction, thereby achieving real-time cooling of the focusing lens 5 and ensuring that the focusing lens 5 is always in a stable working temperature range, thus ensuring the accuracy and efficiency of laser cutting. Furthermore, the cutting head in the cutting area of ​​the equipment can move. The cutting head is the key component of the laser cutting equipment to perform the cutting task. During the cutting process, the cutting head can move precisely within the cutting area according to the preset program and processing requirements to ensure the shape and size accuracy of the cut. For example, when cutting complex workpiece contours, the cutting head can move along various trajectories such as straight lines and curves as needed. In addition, this equipment can realize straight cutting and bevel cutting at different positions: straight cutting means that the cutting head cuts perpendicular to the material surface to form a vertical cutting surface, which is often used for ordinary cutting needs. Bevel cutting, on the other hand, involves the cutting head cutting the material at a certain angle to form an inclined edge on the workpiece. It is mainly used for pre-welding preparation work to increase the welding surface area and improve the welding quality. Cutting at different positions means that, according to the design requirements of the workpiece, straight cutting and bevel cutting methods are used in different parts of the material respectively. In addition, this equipment can shorten the length of the straight-cut tail material: the straight-cut tail material refers to the remaining material that cannot be used for the current cutting task after the straight-cut process is completed. Shortening the length of the straight-cut tail material means reducing material waste and improving material utilization. By rationally planning the movement path of the cutting head during straight-cutting and bevel cutting, unnecessary cutting losses can be reduced. For example, when cutting pipes, the priority first / last cut straight-cut function can be used. When the pipe end is relatively neat, the first cut straight cut can be skipped, reducing the processing path. If the tail material has unprocessable areas, but the pipe end can be aligned without cutting, it is equivalent to utilizing the tail material, thus improving material utilization.

[0024] Reference Figures 7-12Furthermore, the cutting assembly 4 also includes a base 42, one end of which is fixedly connected to the mounting base 41. A limiting groove 421 is formed on the inner wall of the base 42. A housing 43 is detachably connected to the end of the base 42 away from the mounting base 41. A vertical cylinder 46 is provided inside the housing 43, one end of which is fixedly connected to the inner wall of the base 42. The cutting assembly 4 also includes a focusing mechanism 47, which includes a lens barrel 471. A focusing lens 5 is fixedly connected to the inner wall of the lens barrel 471. A telescopic tube 477 is fixedly connected to one end of the lens barrel 471, and the end of the telescopic tube 477 away from the lens barrel 471 is connected to the mounting base 41. The lower side of 1 is fixedly connected, and the telescopic tube 477 is connected to the inner cavity of the cavity 411 and the inner cavity of the lens tube 471 respectively. The lens tube 471 is located on one side of the vertical tube 46. The outer wall of the lens tube 471 is fixedly connected to a sliding plate 472 that slides against the inner wall of the limiting slide groove 421. A telescopic spring 473 is fixedly connected to one side of the sliding plate 472. The end of the telescopic spring 473 away from the sliding plate 472 is fixedly connected to the inner wall of the limiting slide groove 421. A fixing plate 478 is fixedly connected to the outer wall of the lens tube 471. One side of the fixing plate 478 is fixedly connected to the moving end of the cylinder 8. A displacement sensor 479 is fixedly connected to the other side of the fixing plate 478.

[0025] The base 42 and the focusing mechanism 47 work together: As the core support and transmission connection unit of the cutting assembly 4, the base 42 is structurally designed and deeply integrated with the movement and cooling functions of the focusing mechanism 47. From the perspective of structural support and assembly logic, one end of the base 42 is fixedly connected to the mounting base 41, which can form a stable mechanical transmission path between the laser emitter 7, collimating lens 6 and other optical components on the mounting base 41 and the subsequent focusing mechanism 47, avoiding optical path deviation caused by component loosening during the cutting operation. The end of the base 42 away from the mounting base 41 is assembled with the housing 43 in a detachable connection manner, which is convenient for the later maintenance and repair of the internal focusing mechanism 47 (such as replacing the focusing lens 5 and cleaning impurities), and can also form a closed protective space through the housing 43 to isolate the interference of external dust and debris to the focusing mechanism 47. The vertical cylinder 46 inside the housing 43 is fixed to the inner wall of the base 42, and its position corresponds to the lens barrel 471. It can play an auxiliary limiting role during the movement of the lens barrel 471, preventing the lens barrel 471 from shifting laterally due to high-speed adjustment or vibration, and ensuring the stability of optical path transmission. In the focusing lens 5 position adjustment stage, this design achieves precise control through the coordinated action of cylinder 8 and elastic buffer: the lens barrel 471 serves as the main support for the focusing lens 5, and its outer wall sliding plate 472 and the limiting groove 421 on the inner wall of the base 42 form a sliding fit. The trajectory of the limiting groove 421 directly constrains the movement direction of the lens barrel 471 (ensuring that the lens barrel 471 only moves along the preset axial or radial direction, avoiding deviation). When it is necessary to adjust the position of the focusing lens 5 to adapt to different pipe cutting requirements (such as different focal positions required for pipes of different thicknesses), the moving end of cylinder 8 will drive the lens barrel 471 to move synchronously through the fixed plate 478. When cylinder 8 extends, it pushes the lens barrel 471 towards the cutting area; when cylinder 8 retracts, it pulls the lens barrel 471 away from the cutting area. During the movement of the cutting area, the slide plate 472 slides with the lens barrel 471 within the limiting slide groove 421, while simultaneously compressing or stretching the telescopic spring 473 on one side. When the cylinder 8 drives the lens barrel 471 to move to the target position, the telescopic spring 473 generates a reverse elastic force to counteract the inertial impact force during the movement of the lens barrel 471, allowing the lens barrel 471 to quickly stabilize at the preset position and avoid position overshoot caused by inertia. In addition, the displacement sensor 479 on the fixed plate 478 can monitor the moving distance of the lens barrel 471 in real time and feed the data back to the equipment control system. If the displacement deviation exceeds the allowable range, the system can adjust the action of the cylinder 8 in time to ensure the accuracy of the position adjustment of the focusing lens 5, thereby ensuring the precise alignment of the laser focus with the tube cutting surface. In terms of the coordinated transmission of cooling function, the telescopic tube 477 at one end of the lens barrel 471 plays a key flexible connection role: one end of the telescopic tube 477 is connected to the inner cavity of the lens barrel 471, and the other end is connected to the cavity 411 of the mounting base 41. It does not hinder the movement of the lens barrel 471 with the cylinder 8 (the telescopic tube 477 can extend and deform synchronously when the lens barrel 471 is adjusted, avoiding pipe breakage caused by rigid connection), and can continuously supply coolant to the focusing lens 5 inside the lens barrel 471. When the coolant in the cavity 411 of the mounting base 41 is guided by the partition plate 412, it will flow into the inner cavity of the lens barrel 471 through the telescopic tube 477, forming a cooling circuit around the focusing lens 5, and carrying away the focusing fluid. The heat generated by the focusing lens 5 during operation; at the same time, the sealing design of the telescopic tube 477 can prevent coolant leakage, ensure stable cooling effect, and avoid optical performance degradation or structural damage caused by overheating of the focusing lens 5. During the entire operation, the base 42 achieves precise constraint and support for the focusing mechanism 47 through the limiting slide groove 421 and the vertical cylinder 46. The cylinder 8 and the telescopic spring 473 cooperate to complete the flexible adjustment of the position of the focusing lens 5. The displacement sensor 479 ensures the adjustment accuracy, and the telescopic tube 477 simultaneously realizes the flexible connection of the cooling channel. The coordinated action of all components ensures that the focusing mechanism 47 can not only accurately adapt to different cutting needs, but also operate stably for a long time.

[0026] Furthermore, a fixing ring 476 is fixedly connected to the outer wall of the mirror tube 471, and an electromagnetic coil 4710 is provided on the inner wall of the fixing ring 476. A rotating cylinder 475 is rotatably connected to the end of the mirror tube 471 away from the telescopic tube 477. The rotating cylinder 475 is located inside the electromagnetic coil 4710, and a magnetic block 4711 that cooperates with the electromagnetic coil 4710 is provided inside the rotating cylinder 475. Several turbine blades 474 arranged in a circular array are fixedly connected to the outer wall of the rotating cylinder 475, and an agitating blade 4751 is fixedly connected to the end of the rotating cylinder 475 located inside the mirror tube 471.

[0027] Electromagnetic drive and airflow protection mechanism: At the end of the lens barrel 471 of the focusing mechanism 47, the design of the rotating cylinder 475 fully considers the synergistic requirements of driving force and stability. Multiple magnetic blocks 4711 are evenly distributed in an array along the circumference of the rotating cylinder 475. This layout ensures that the magnetic field generated by the magnetic blocks 4711 forms a continuous and balanced magnetic field ring on the outer circumference of the rotating cylinder 475, avoiding jamming or swaying during rotation due to uneven magnetic field distribution. Corresponding to the magnetic blocks 4711 is the electromagnetic coil 4710 on the inner wall of the fixed ring 476. When the electromagnetic coil 4710 is connected to current, it will generate an electromagnetic field in a specific direction according to the magnetic effect of the current. This electromagnetic field interacts with the magnetic field of the magnetic blocks 4711 on the rotating cylinder 475 (like poles repel, unlike poles attract), and is then converted into torque to drive the rotating cylinder 475 to rotate. When the electromagnetic coil 4710 is energized, the magnetic field it generates continuously creates alternating repulsive and attractive forces with the multiple magnetic blocks 4711, giving the rotating cylinder 475 continuous and stable rotational power. This causes the cylinder to rotate rapidly at the end of the mirror tube 471. The turbine blades 474, fixed to the outer wall of the rotating cylinder 475, rotate synchronously at high speed with the cylinder. The special structural design of the turbine blades 474 can change the flow state of the surrounding air during rotation. When the blades rotate, they compress the air on one side and create a low-pressure area, i.e., a negative pressure environment, on the other side. Under the action of negative pressure, the air inside the base 42 forms a directional, rapid airflow, which flows precisely towards the laser cutting. In the end region, on the one hand, the rapidly flowing airflow can form an "air curtain" at the cutting end, effectively blocking metal residues, dust and other impurities generated during the cutting process from diffusing into the focusing lens 5 or the lens barrel 471; on the other hand, the airflow can also promptly remove some of the spatter generated by the laser near the cutting end, preventing these residues from adhering to the cutting surface or equipment parts. This airflow protection achieved by electromagnetic drive does not require an additional pneumatic drive device, and directly utilizes the rotational power of the rotating cylinder 475 to form a protective airflow, which simplifies the structural design and can provide continuous protection in real time in conjunction with the cutting operation, ensuring the cleanliness of the cutting end and the service life of the equipment parts; Furthermore, the stirring blade 4751 is fixed to one end of the rotating cylinder 475 located inside the lens barrel 471 and rotates synchronously with the rotating cylinder 475. The rotation of the stirring blade 4751 can actively stir the coolant inside the lens barrel 471. When the blade rotates, it breaks the static state of the coolant, pushes the low-temperature coolant to flow quickly to the surface of the focusing lens 5, and at the same time carries away the high-temperature coolant after absorbing heat in time, avoiding the formation of temperature stratification of the coolant near the focusing lens 5. Through this dynamic stirring, the coolant forms a uniform circulation in the inner cavity of the lens barrel 471, ensuring that all areas of the focusing lens 5 can fully contact the low-temperature coolant, solving the problem of "insufficient local heat dissipation", ensuring that the focusing lens 5 is in a stable operating temperature range for a long time, and avoiding laser focus drift caused by thermal deformation. Moreover, the rotation of the stirring blade 4751 does not consume additional power and is directly achieved by the electromagnetically driven rotating cylinder 475. While improving the heat dissipation effect, it avoids the increase of equipment energy consumption, which meets the requirements of structural integration and energy-saving design.

[0028] Example 2 Reference Figure 5 , Figure 6 , Figure 7 and Figure 11 Furthermore, the cutting assembly 4 also includes a protective mechanism 44, which includes a storage cylinder 441 and a protective sleeve 442. One end of the protective sleeve 442 is fixedly connected to the end of the housing 43 away from the base 42. The storage cylinder 441 is fixedly sleeved on the outer wall of the protective sleeve 442. A ventilation groove 445 is provided inside the protective sleeve 442. One end of the ventilation groove 445 is connected to the storage cylinder 441. A plurality of circumferentially arrayed suction holes 443 are provided on the inner wall of the ventilation groove 445. A plurality of evenly distributed adsorption plates 444 are fixedly connected to the inner wall of the storage cylinder 441. A connecting pipe 45 is fixedly connected to the outer wall of the storage cylinder 441. A filter plate 451 is provided on the inner wall of the connecting pipe 45. The end of the connecting pipe 45 away from the storage cylinder 441 is fixedly connected to the base 42.

[0029] The synergistic design of the storage tube 441 and the protective sleeve 442: The two together can build a dual protection system of "active adsorption + isolation protection". From the perspective of structural cooperation, one end of the protective sleeve 442 is fixed to the end of the shell 43 away from the base 42, which can isolate the laser cutting operation area from the internal components of the equipment, forming a physical protective barrier to prevent the splatter generated during cutting from directly hitting or scratching the core components of the equipment. The ventilation groove 445 opened inside the protective sleeve 442 provides a channel for the transmission of airflow and impurities. The air intake holes 443 on the inner wall of the ventilation groove 445 are arranged in a circumferential array, which can ensure that the airflow and impurities drawn in from the cutting area can enter the ventilation groove 445 evenly, avoiding impurity residue caused by insufficient local air intake. In the airflow drive and impurity collection stage, the protective mechanism 44 relies on the overall airflow system of the equipment (such as the negative pressure generated by the rotation of the turbine blades 474): When the cutting operation starts, the negative pressure generated by the high-speed rotation of the turbine blades 474 will be transmitted to the inside of the collection cylinder 441 through the connecting pipe 45, so that the inside of the collection cylinder 441 is maintained at a low pressure. At this time, the smoke and dust generated in the cutting area will be drawn by the negative pressure and enter the ventilation groove 445 through the air intake hole 443 on the protective sleeve 442. Then, it will flow into the inside of the collection cylinder 441 through the connection between the ventilation groove 445 and the collection cylinder 441, completing the initial collection and guidance of impurities and preventing smoke and dust from spreading to the working environment or the inside of the equipment. Furthermore, impurities entering the collection cylinder 441 undergo further adsorption and filtration. The adsorption plate 444 fixed on the inner wall of the collection cylinder 441 can adsorb magnetic impurities in the airflow (such as iron powder and iron filings generated from metal cutting). Through physical adsorption, some impurities are intercepted in the collection cylinder 441, reducing the burden on subsequent filtration stages. Fine dust and non-magnetic residues that are not adsorbed continue to flow with the airflow towards the connecting pipe 45. When the airflow passes through the filter plate 451 on the inner wall of the connecting pipe 45, the filter plate 451 intercepts these tiny impurities, allowing only clean airflow to enter the base 42 through the connecting pipe 45 (which can eventually be connected to the equipment's exhaust or circulation system). The entire protection process forms a closed-loop process, which not only achieves clean protection of the cutting operation area, preventing impurities from affecting cutting accuracy and equipment lifespan, but also reduces the pollution of the working environment by smoke and dust. At the same time, through the graded treatment of the adsorption plate 444 and the filter plate 451, the risk of impurities clogging the pipes is reduced, ensuring the long-term stable operation of the protection mechanism 44.

[0030] It should be noted that the specific model and specifications of the electrical components need to be selected and determined based on the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be described in detail here.
