A CNC laser cutting machine tool for processing fan parts

Abstract

This invention discloses a CNC laser cutting machine tool for processing wind turbine parts, relating to the field of laser cutting equipment technology. It includes a machine body, a laser mounted outside the machine body via a drive assembly, and is characterized by further including a laser-following protection mechanism located at the bottom of the laser, and a traveling and unloading mechanism located inside the laser-following protection mechanism. The laser-following protection mechanism and the traveling and unloading mechanism enable a cylindrical block to move synchronously with the laser trajectory, ensuring that, during curved cutting, the anti-laser block inside the cylindrical block is always directly below the laser beam, thus providing protection. Simultaneously, the rollers in the traveling and unloading mechanism and the forward and reverse top blocks inside the top slide rail groove cause the moving plate and the scraper cutter to vibrate up and down, automatically scraping away and cleaning the hardened slag and molten metal residue that has cooled and solidified on both sides of the bottom of the sheet metal.

Description

Technical Field

[0001] This invention relates to the field of laser cutting equipment technology, specifically to a CNC laser cutting machine tool for processing fan parts. Background Technology

[0002] CNC laser cutting machine tools for wind turbine parts processing are CNC blanking equipment specifically designed for wind turbine parts processing. They utilize a laser to generate a high-energy laser beam, which, together with a drive assembly, drives the laser head to move precisely. By melting the sheet material with the laser, the machine cuts out the outline of various wind turbine parts such as wind turbine blades and flanges, completing the sheet material shaping process.

[0003] When cutting the curved shape of fan blades on a CNC laser cutting machine, the machine table uses a serrated support table to support the plate. This support table has a regularly arranged toothed distribution and is only suitable for laser straight cutting. When traveling in a straight line, the laser can pass vertically through the gaps in the serrations without burning the support teeth.

[0004] However, the fan blades have a continuous irregular curved profile, and the laser cutting head moves arbitrarily along the curved trajectory, making it impossible to always align with the gap between the blades. After the laser penetrates the plate, it will randomly sweep and burn the serrated structure below, causing the blades to be eroded, deformed, and damaged. Long-term use will lead to uneven support of the plate and a decrease in cutting accuracy.

[0005] Meanwhile, the high-pressure auxiliary airflow, coaxial with the cutting head and pointing downwards, forcibly compresses and accumulates the molten metal slag produced during cutting on both sides of the bottom of the cut edge of the plate. The molten slag solidifies and hardens rapidly upon cooling, forming a firm slag deposit and burrs, requiring an additional grinding and deburring process, thus increasing processing steps and production costs.

[0006] To address the aforementioned issues, there is an urgent need for innovative design based on the existing CNC laser cutting machine tools used for processing wind turbine parts. Summary of the Invention

[0007] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a CNC laser cutting machine tool for processing wind turbine parts, thereby solving the problems mentioned in the background art. Traditional laser cutting machine tools use a fixed serrated support table, which easily burns and damages the support structure during curved cutting, reduces cutting accuracy, and causes molten slag to cool and adhere to the bottom of the cut edge of the plate, forming slag burrs that require additional secondary grinding.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a CNC laser cutting machine tool for processing wind turbine parts, comprising a machine body, a laser disposed outside the machine body via a drive assembly, characterized in that it further comprises: A laser-following protection mechanism is located at the bottom of the laser; The walking and unloading mechanism is installed inside the laser-following protection mechanism; The laser following protection mechanism includes an outer frame disposed on the outer wall of the machine body, and a top slide rod is movably disposed on the outer wall of the outer frame. The top slide rod has symmetrical grooves on both sides of the top of the outer wall. The walking and unloading mechanism includes a positive top block disposed inside a side chute, a reverse top block disposed on the inner wall of the top slide bar chute on the other side, a bottom slide bar movably connected to the bottom of the top slide bar, and a cylindrical block movably disposed on the inner wall of the bottom slide bar. The positive top block consists of two parts: an arc-shaped gently rising surface and a vertical drop surface; The positive top block and the negative top block have the same appearance; The forward top block and the reverse top block are mirror images of each other and are located inside the grooves of the top slide bars on both sides. The walking and unloading mechanism also includes a movable plate movably disposed on the top of the outer wall of the bottom slide bar. A connecting block is provided at the bottom of the movable plate, a top rod is provided at the bottom of the connecting block, and a roller is provided at one end of the top rod. The forward and reverse top blocks enable the moving plate to store energy through the arc-shaped gradual rise surface during movement, release energy rapidly through the vertical drop surface to trigger the rollers to impact and fall quickly, and use the impact reaction force to trigger the moving plate to vibrate and remove chips. The outer walls of the outer frame are all equipped with adjustable clamps.

[0009] Preferably, the cylindrical block has a cavity; An offset block is provided inside the cavity of the cylindrical block; A connecting rod is connected to the bottom of the outer wall of the cylindrical block; One end of the connecting rod is connected to the laser.

[0010] Preferably, a return spring is provided around the outer wall of the top rod; A scraper cutter is provided on the top of the outer wall of the movable plate; The top rod passes through the connecting block; The push rod can be driven to slide up and down when the roller moves.

[0011] Preferably, a telescopic rod is provided at the top of the outer wall of the connecting block; The outer wall of the telescopic rod is surrounded by a vibration spring.

[0012] Preferably, the telescopic rods are distributed in a circular pattern around the top of the outer wall of the connecting block; One end of the telescopic rod is connected to the top of the outer wall of the connecting block; The other end of the telescopic rod is connected to the movable plate.

[0013] Preferably, the inner wall of the movable plate is inclined; The movable plate is hollow; The movable plate is movably connected to the cylindrical block.

[0014] Preferably, the positive top blocks are arranged in a pattern within the groove of one side of the top slide bar; The reverse top blocks are arranged in a mirror image within the groove of the top slide bar on the other side.

[0015] Preferably, both the top slide rod and the bottom slide rod have cavities. The diameter of the cavity opened by the top slide rod and the bottom slide rod is adapted to the diameter of the cylindrical block.

[0016] Preferably, the cylindrical block is connected to the connecting block; The connecting block is movably connected to the top slide bar and the bottom slide bar.

[0017] Preferably, the offset block is disposed in the cavity of the cylindrical block; The offset block is made of aluminum oxide.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. By using a laser-following protection mechanism and a walking unloading mechanism, the cylindrical block moves synchronously with the laser, ensuring that the counteracting block inside the cylindrical block is always directly below the laser beam during curved cutting. After the laser penetrates the material, its energy naturally attenuates with increasing propagation distance. The counteracting block, made of alumina, then blocks and absorbs the residual laser beam with high temperature resistance, avoiding the problems of ablation, deformation, and damage to the table support structure caused by blade curved cutting and irregular laser sweeping in traditional serrated support tables. This effectively reduces high-temperature wear and burns on machine tool support components, maintains the stability of the material placement and cutting accuracy for a long time, and thus improves the overall service life of the equipment.

[0019] 2. Through the rollers in the walking unloading mechanism and the positive and negative top blocks inside the top slide rail groove (whose arc-shaped gradual rise surface and vertical drop surface form an undulating structure), the rollers are driven to slide and generate regular lifting and lowering motion, so that the moving plate and the scraper cutter form an up-and-down vibration motion, thereby automatically scraping and cleaning the hard slag and molten metal slag that have cooled and solidified on both sides of the bottom of the plate cut. The scraped slag automatically slides down the inclined hollow structure of the moving plate and the inclined outer wall of the offset block to the bottom of the machine body for discharge, saving the cost of manual secondary grinding and deburring, eliminating additional processing steps, reducing the intensity of manual labor, and thus reducing the subsequent processing time of fan parts, thereby reducing production costs and further improving the overall processing efficiency of fan parts.

[0026] 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, and 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.

[0027] Please see Figures 1 to 20 The present invention provides a technical solution: a CNC laser cutting machine tool for processing wind turbine parts, comprising a machine body 1, a laser 2 disposed outside the machine body via a drive assembly, characterized in that it further comprises: Laser following protection mechanism 3 is set at the bottom of laser 2; The walking and unloading mechanism 4 is installed inside the laser following and protection mechanism 3; The laser following protection mechanism 3 includes an outer frame 308 set on the outer wall of the body 1. A top slide bar 301 is movably set on the outer wall of the outer frame 308. Slide grooves are symmetrically opened on both sides of the top of the outer wall of the top slide bar 301. The walking material feeding mechanism 4 includes a positive top block 302 disposed inside a chute on one side, a reverse top block 303 disposed on the inner wall of the chute of the top slide rod 301 on the other side, a bottom slide rod 304 movably connected to the bottom of the top slide rod 301, and a cylindrical block 305 movably disposed on the inner wall of the bottom slide rod 304. The positive top block 302 consists of two parts: an arc-shaped gently rising surface and a vertical drop surface; The appearance of the forward top block 302 and the reverse top block 303 is identical; The forward top block 302 and the reverse top block 303 are mirror images of each other and are located inside the grooves of the top slide bars 301 on both sides; The walking material feeding mechanism 4 also includes a movable plate 401 that is movably disposed on the top of the outer wall of the bottom slide bar 304. A connecting block 403 is provided at the bottom of the movable plate 401, a top rod 404 is provided at the bottom of the connecting block 403, and a roller 406 is provided at one end of the top rod 404. The forward top block 302 and the reverse top block 303 enable the moving plate 401 to store energy through the arc-shaped gradual rise surface when moving, and release energy quickly through the vertical drop surface to trigger the roller 406 to quickly impact and fall, and use the impact reaction force to trigger the moving plate 401 to vibrate and remove chips. The outer walls of the outer frame 308 are all equipped with adjustable clamps 5.

[0028] In this embodiment, the cylindrical block 305 moves synchronously with the laser 2 via the laser-following protection mechanism 3 and the walking unloading mechanism. This ensures that the canceling block 307 inside the cylindrical block 305 is always directly below the laser beam during curved cutting. After the laser penetrates the material, its energy naturally attenuates with the increase of propagation distance. The canceling block 307, made of alumina, then blocks and absorbs the residual laser beam at high temperatures. This avoids the problems of ablation, deformation, and damage to the table support structure caused by the curved cutting of the blades and irregular laser sweeping of the traditional sword-grid saw table. It effectively reduces the high-temperature loss and burning wear of the machine tool support components, maintains the stability of the material placement and the cutting accuracy for a long time, and thus improves the overall service life of the equipment.

[0029] The cylindrical block 305 has a cavity; An anti-cancellation block 307 is provided inside the cavity of the cylindrical block 305; A connecting rod 306 is connected to the bottom of the outer wall of the cylindrical block 305; One end of the connecting rod 306 is connected to the laser 2.

[0030] In this embodiment, the rollers 406 in the walking and unloading mechanism 4 and the positive and negative top blocks 302 and 303 inside the top slide bar 301 (whose arc-shaped rising surface and vertical drop surface form an undulating structure) drive the rollers 406 to slide and generate regular lifting and lowering motion. This causes the moving plate 401 and the scraper cutter 402 to form an up-and-down vibration motion, thereby automatically scraping and cleaning the hard slag and molten metal slag that have cooled and solidified on both sides of the bottom of the plate cut. The scraped slag automatically slides down the inclined hollow structure of the moving plate 401 and the inclined outer wall of the offset block 307 to the bottom of the machine body 1 for discharge. This saves the cost of manual secondary grinding and deburring, eliminates additional processing steps, reduces the intensity of manual labor, and reduces the subsequent processing time of fan parts, thereby reducing production costs and further improving the overall processing efficiency of fan parts.

[0031] A return spring 405 is provided around the outer wall of the push rod 404; A scraper cutter 402 is provided on the top of the outer wall of the movable plate 401; The push rod 404 passes through the connecting block 403; The push rod 404 can slide up and down when the roller 406 moves.

[0032] In this embodiment, the cutting board first needs to be fixed. Specifically, the user adjusts the position of the three adjustable clamps 5. The adjustable clamps 5 are movable and can slide along the outer wall of the outer frame 308. They can also slide back and forth and adjust their height. Then, they are clamped according to the size of the board. After the board is clamped, it can be cut. It is necessary to keep a small distance between the scraper cutter 402 on the outer wall of the moving plate 401 and the board, but not too far away.

[0033] A telescopic rod 407 is provided on the top of the outer wall of the connecting block 403; A vibration spring 408 is provided around the outer wall of the telescopic rod 407.

[0034] In this embodiment, when the laser 2 is driven to cut the plate, the laser 2 will move. When the laser 2 moves, the connecting rod 306, because it is connected to the laser 2, will also move along the same trajectory. When the connecting rod 306 moves, it will drive the cylindrical block 305 to move through its other end. When the cylindrical block 305 moves, it will move along the cavity of the top slide rod 301 and the bottom slide rod 304. Since the trajectory of the cylindrical block 305 is curved, the cylindrical block 305 will apply a squeezing force to the top slide rod 301 and the bottom slide rod 304 when it moves. When the cylindrical block 305 moves, the top slide rod 301 will slide left and right along the outer wall of the outer frame 308.

[0035] The telescopic rods 407 are distributed in a ring around the top of the outer wall of the connecting block 403; One end of the telescopic rod 407 is connected to the top of the outer wall of the connecting block 403; The other end of the telescopic rod 407 is connected to the movable plate 401.

[0036] In this embodiment, when the connecting rod 306 moves, it drives the cylindrical block 305 to move through its other end. When the cylindrical block 305 moves, it moves along the cavity of the top slide rod 301 and the bottom slide rod 304. Since the trajectory of the cylindrical block 305 is curved, the cylindrical block 305 will apply a squeezing force to the top slide rod 301 and the bottom slide rod 304 when it moves. When the cylindrical block 305 moves, the top slide rod 301 will slide left and right along the outer wall of the outer frame 308, while the bottom slide rod 304 will slide back and forth along the outer wall of the outer frame 308. This makes the movement trajectory of the cylindrical block 305 synchronized with that of the laser 2. When the laser 2 cuts and emits high-heat rays, the laser will penetrate the plate. Since the laser is vertically and synchronously irradiated downwards, the laser will irradiate the interior of the cylindrical block 305 through the hollow structure of the moving plate 401.

[0037] The inner wall of the movable plate 401 is inclined; The movable plate 401 is hollow; The movable plate 401 is movably connected to the cylindrical block 305.

[0038] In this embodiment, the cylindrical block 305 has an internal counteracting block 307, which is made of alumina and has high temperature resistance and heat insulation properties. It does not reflect laser light. Also, because the counteracting block 307 is a certain distance from the laser 2, the laser light emitted by the laser 2 will travel a certain distance after penetrating the plate, resulting in energy reduction. The laser light will then be counteracted by the counteracting block 307. When the laser 2 cuts and blows out high-pressure air, it will blow the slag into the two sides of the bottom of the plate. When the cylindrical block 305 moves, the moving plate 401 will also move synchronously. When the moving plate 401 moves, the connecting block 403 will also move synchronously. The roller 406 at the bottom of the connecting block 403 will slide along the groove opened in the top slide bar 301. Because the groove of the top slide bar 301 is provided with a forward top block 302 and a reverse top block 303, when the roller 406 slides to one side, it will first slide along the arc-shaped gently rising surface of the forward top block 302.

[0039] The positive top blocks 302 are arranged in a pattern within the groove of the top slide bar 301 on one side; The reverse top blocks 303 are arranged in a mirror image within the groove of the top slide bar 301 on the other side.

[0040] In this embodiment, the roller 406 will drive the top rod 404 to slide upward. When it reaches the vertical drop surface, the return spring 405 will release its elastic force to drive the top rod 404 and the roller 406 to fall quickly. During this process, when the roller 406 moves to the arc-shaped rising surface of the positive top block 302, the top rod 404 will first lift the moving plate 401. When the moving plate 401 is lifted, the vibration spring 408 will be stretched. When the roller 406 moves to the vertical drop surface of the positive top block 302, the return spring 405 will release its elastic force to drive the top rod 404 to reset quickly. After the top rod 404 resets, the moving plate 401 will be driven to reset quickly downward by the rebound force generated by the vibration spring 408 after the top rod 404 is no longer limited. The rebound force generated when the moving plate 401 resets quickly will generate a mutual impact force with the vibration spring 408.

[0041] Both the top slide bar 301 and the bottom slide bar 304 have cavities. The diameters of the cavities formed by the top slide bar 301 and the bottom slide bar 304 are adapted to the diameter of the cylindrical block 305.

[0042] In this embodiment, after the push rod 404 is reset, the moving plate 401, no longer limited by the push rod 404, will be driven downward and quickly reset by the rebound force generated by the vibration spring 408. The rebound force generated when the moving plate 401 is quickly reset will generate a mutual impact force with the vibration spring 408, causing the moving plate 401 to vibrate rapidly. Conversely, when the moving plate 401 moves to the other side, the roller 406 will be driven by the reverse push block 303 to make the moving plate 401 vibrate and shake off the residue. Regardless of which side it moves from, the moving plate 401 is vibrated by the forward push block 302 and the reverse push block 303 from one side.

[0043] The cylindrical block 305 is connected to the connecting block 403; The connecting block 403 is movably connected to the top slide bar 301 and the bottom slide bar 304.

[0044] In this embodiment, regardless of which side the movement is from, the moving plate 401 is vibrated by the forward top block 302 and the reverse top block 303 from one side. The slag part of the material being cut by the laser 2 will be blown onto the outer wall of the moving plate 401. Since the moving plate 401 is in an active state and the outer wall of the moving plate 401 is inclined, the slag will fall into the inner wall of the cylindrical block 305 through the inclined outer wall of the moving plate 401 and the state of vibration. Also, because one end of the counteracting block 307 is inclined.

[0045] The offset block 307 is disposed in the cavity of the cylindrical block 305; The material of the offset block 307 is aluminum oxide.

[0046] In this embodiment, the slag will be shaken off into the inner wall of the cylindrical block 305 through the inclined outer wall of the moving plate 401 and the vibration state. Since one end of the counteracting block 307 is inclined, the slag will slide off the inclined outer wall of the counteracting block 307 to the bottom of the machine body 1 for processing. The slag blown to both sides of the plate will be vibrated up and down by the moving plate 401, and the moving plate 401 itself moves horizontally along the shape of the blade. At this time, the scraper cutter 402 can scrape the slag off onto the outer wall of the moving plate 401, and the slag is discharged in the above manner.

[0047] Working principle: When using this type of CNC laser cutting machine tool for processing fan parts, such as Figure 1 , Figure 2 and Figure 3As shown, the material to be cut first needs to be fixed. The specific fixing method is that the user adjusts the position of the three adjustable clamps 5. The adjustable clamps 5 are movable and can slide along the outer wall of the outer frame 308. They can also slide back and forth and adjust their height. Then, clamp them according to the size of the material. After the material is clamped, it can be cut. It is necessary to keep a small distance between the scraper cutter 402 set on the outer wall of the moving plate 401 and the material, but not too far away.

[0048] When the user drives the laser 2 to cut the plate, the laser 2 will move. As the laser 2 moves, the connecting rod 306, because it is connected to the laser 2, will also move along the same trajectory. When the connecting rod 306 moves, it will drive the cylindrical block 305 to move through its other end. When the cylindrical block 305 moves, it will move along the cavity of the top slide rod 301 and the bottom slide rod 304. Because the trajectory of the cylindrical block 305 is curved, the cylindrical block 305 will apply a squeezing force to the top slide rod 301 and the bottom slide rod 304 when it moves. When the cylindrical block 305 moves, the top slide rod 301 will slide left and right along the outer wall of the outer frame 308, while the bottom slide rod 304 will slide back and forth along the outer wall of the outer frame 308. This makes the movement trajectory of the cylindrical block 305 and the laser 2 synchronized.

[0049] When the laser 2 emits high-heat rays during cutting, the laser will penetrate the plate. Since the laser is vertically and synchronously irradiated downwards, it will then irradiate the interior of the cylindrical block 305 through the hollow structure of the moving plate 401. Because the cylindrical block 305 has a counteracting block 307 inside, and the counteracting block 307 is made of alumina which has high temperature resistance and heat insulation properties, it will not reflect the laser. At the same time, because the counteracting block 307 is a certain distance from the laser 2, the laser emitted by the laser 2 will travel a certain distance after penetrating the plate, resulting in a reduction in energy. The laser will then be counteracted by the counteracting block 307. When the laser 2 cuts and blows out high-pressure air, it will blow the slag into the bottom sides of the plate.

[0050] When the cylindrical block 305 moves, the moving plate 401 also moves synchronously. When the moving plate 401 moves, the connecting block 403 also moves synchronously. The roller 406 at the bottom of the connecting block 403 slides along the groove opened in the top slide rod 301. Because the groove of the top slide rod 301 is provided with a forward top block 302 and a reverse top block 303, when the roller 406 slides to one side, it will first slide along the arc-shaped rising surface of the forward top block 302. At this time, the roller 406 will drive the top rod 404 to slide upward. When it reaches the vertical drop surface, the return spring 405 will release the elastic force to drive the top rod 404 and the roller 406 to fall quickly. During this process, when the roller 406 moves along the arc-shaped rising surface of the forward top block 302, the top rod 404 will first lift the moving plate 401. The moving plate 401 is lifted When the vibration spring 408 is stretched, and the roller 406 moves to the vertical drop surface of the positive top block 302, the return spring 405 will release its elastic force to drive the top rod 404 to quickly return to its original position. After the top rod 404 returns to its original position, the moving plate 401 will be driven to quickly return to its original position downward by the rebound force generated by the vibration spring 408. The rebound force generated when the moving plate 401 quickly returns to its original position will have a mutual impact force with the vibration spring 408, causing the moving plate 401 to vibrate rapidly. Conversely, when the moving plate 401 moves to the other side, the roller 406 will be driven by the reverse top block 303 to make the moving plate 401 vibrate and shake off the residue. Regardless of which side it moves from, the positive top block 302 and the reverse top block 303 drive the moving plate 401 to vibrate from one side.

[0051] During laser cutting, the slag is blown onto the outer wall of the moving plate 401. Since the moving plate 401 is in a moving state and its outer wall is inclined, the slag will fall into the inner wall of the cylindrical block 305 through the inclined outer wall of the moving plate 401 and the vibration. Since one end of the counteracting block 307 is inclined, the slag will slide down to the bottom of the machine body 1 through the inclined outer wall of the counteracting block 307 and can then be processed. The slag blown to both sides of the plate will vibrate up and down through the moving plate 401, and the moving plate 401 itself moves horizontally along the shape of the blade. At this time, the scraper cutter 402 can scrape the slag onto the outer wall of the moving plate 401. The slag is discharged in the above manner, and the work of the present invention is completed.

[0052] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
