Description

Technical Field

[0001] The present invention relates to the technical field of loom accessory processing, and particularly relates to a laser cutting device for loom accessory production. Background Art

[0002] In the existing technology, laser cutting will cause slag, and the slag may form defects such as burrs and slag hanging at the cut, affecting the flatness and perpendicularity of the cut. This will not only increase the workload of subsequent cleaning and processing, but also may lead to a decrease in the mechanical properties at the cut, such as a reduction in indicators such as the strength and toughness of the cut.

[0003] Most of the existing methods for treating slag adopt direct blowing. However, due to the unidirectional airflow, in some parts of the cutting area, the airflow coverage may be insufficient, resulting in the hot slag in these parts not being blown away in time, thus affecting the cutting quality. In addition, during the slag blowing process, the airflow will form a longitudinal turbulent flow around the cutting area, causing some of the blown hot slag to fall back onto the cutting surface again, resulting in secondary adhesion.

Specific embodiments

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Referring to Figures 1 to 9 , a laser cutting device for loom accessory production includes a control console 1. In the middle position on the upper surface of the control console 1, there is a containing groove 2. At the four corners inside the containing groove 2, there are first electric slide grooves 7 and electric slide plates 6. The electric slide plates 6 are slidably connected to the first electric slide grooves 7. Starting the electric slide plates 6 and the first electric slide grooves 7 can make the electric slide plates 6 move up and down in the first electric slide grooves 7. At the upper part of the corners, a fixing plate 8 is detachably installed. The fixing plate 8 is arranged in parallel with the electric slide plates 6. By adjusting the distance between the fixing plate 8 and the electric slide plates 6, the four corners of the material plate can be fixed.

[0034] Second electric slide grooves 9 are provided on both the front and rear side walls of the containing groove 2. An electric slide part 10 slidably connected to the second electric slide grooves 9 is arranged inside the containing groove 2. An electric scraping plate 11 is installed at the upper end of the electric slide part 10. The electric scraping plate 11 is located below the material plate and has a telescopic function for scraping the slag attached to the lower surface of the material plate.

[0035] On both sides of the upper end of the console 1, there are horizontally electric sliding tables 3 slidably installed. The horizontally electric sliding tables 3 can move horizontally left and right on the console 1. The upper end of the horizontally electric sliding tables 3 is fixedly installed with vertically electric sliding tables 4. The working end of the vertically electric sliding tables 4 is slidably installed with a laser control part 5. The horizontally electric sliding tables 3, the vertically electric sliding tables 4, and the laser control part 5 are all prior arts, and their specific structural designs will not be elaborated here. By setting the horizontally electric sliding tables 3 and the vertically electric sliding tables 4, the position of the laser control part 5 can be adjusted, so as to facilitate cutting the material plate at an appropriate position.

[0036] On one side of the lower end of the laser control part 5, there is a rear magnetic plate 17 fixedly installed, and on the other side, there are two symmetrically arranged outer blocks 18 fixedly installed. The rear magnetic plate 17 is designed in an inverted stepped shape and faces the side of the outer blocks 18. At the middle position of the lower end of the laser control part 5, there is a laser housing 12 fixedly installed. Inside the lower end of the laser housing 12, there is a ceramic ring 13 fixedly installed. On the upper surface of the ceramic ring 13, there are a plurality of magnetic blocks 15 arranged in a circular array. The upper ends of the plurality of magnetic blocks 15 are commonly connected to an electromagnetic coil 16. The magnetic blocks 15 form a stable magnetic field. After adding the electromagnetic coil 16, a Lorentz force will be formed. The lower end of the ceramic ring 13 is detachably installed with a nozzle 14.

[0037] Inside the outer block 18, there is a vertical inner groove 19 opened. A spiral air duct 20 is installed in the inner groove 19. The spiral air duct 20 is connected to an air pump built in the laser control part 5. Through the air pump, air with a certain flow rate is conveyed into the spiral air duct 20. Below the inside of the outer block 18, there are laterally arranged side air grooves 21 opened. The side air grooves 21 are communicated with the inner groove 19. Inside the side air grooves 21, there are several spoiler fins 22 distributed in a staggered manner. At the outlet of the side air grooves 21, there is a rotating ball 23 rotatably installed. The rotating ball 23 is designed to be horizontally penetrated. At the middle positions of the front and rear sides of the rotating ball 23, there are electric shafts 24. The electric shafts 24 are fixedly installed on the outer block 18, and their working ends are fixedly connected to the rotating ball 23. When the two electric shafts 24 run synchronously, the rotating ball 23 can be driven to rotate in the vertical plane.

[0038] One end of the rotating ball 23 away from the side wind groove 21 is rotatably installed with an inner ring 25. One end of the inner ring 25 away from the rotating ball 23 is fixedly communicated with an outer ring 26. The outer ring 26 is composed of two offset half rings. Cavities are formed in the side walls of the inner ring 25 and the outer ring 26, and the cavities inside the two are communicated. A plurality of outer flow ports 28 are evenly distributed on the inner wall of the outer ring 26. The outer flow ports 28 are communicated with the cavity in the side wall of the outer ring 26. A plurality of inner flow ports 27 are evenly distributed on the inner wall of the inner ring 25. The inner flow ports 27 are communicated with the cavity in the side wall of the inner ring 25, and the inner flow ports 27 are inclined towards the outer ring 26 side, so that the air flow blown out from the inner flow ports 27 blows towards the outer ring 26 side. Outer air ducts 30 are fixedly installed at the places where the two half rings are offset. The outer air ducts 30 are communicated with the cavity in the side wall of the outer ring 26 through the grooves formed in the side wall of the outer ring 26. Inner air ducts 29 are provided on both the upper and lower sides of the side wind groove 21. One end of the inner air duct 29 is communicated with the inside of the side wind groove 21, and the other end is communicated with the outer air duct 30, so that a part of the air flow entering the side wind groove 21 can enter the inner air duct 29, then enter the outer air duct 30, and finally be ejected through the inner flow ports 27 and the outer flow ports 28.

[0039] When the present invention is in use, first place the material plate in the containing groove 2. The containing groove 2 is opened on the control console 1. When the material plate is placed in the containing groove 2, the four corners are in mutual contact with the electric sliding plate 6. Then threadedly connect the fixing plates 8 at the four corners and the control console 1. After the threaded connection, the electric sliding plate 6 automatically lifts upward in the first electric sliding groove 7 until it abuts against the lower surface of the fixing plate 8. At this time, the material plate is in a fixed state. Then the electric sliding member 10 slides in the second electric sliding groove 9, driving the electric scraping plate 11 to move to the position where cutting is required.

[0040] At this time, the laser cutting device needs to move to the specified position. The horizontal electric sliding table 3 moves, thereby driving the laser control member 5 to move left and right (taking Figure 1 as an example). Then the vertical electric sliding table 4 moves, driving the laser control member 5 to move. After reaching the specified position, the laser control member 5 is started, and the laser is emitted to start cutting.

[0041] When the laser starts cutting, the cooperation between the magnetic block 15 and the electromagnetic coil 16 will form a Lorentz force. The electromagnetic coil 16 can control the intensity of the magnetic field according to the output of the current. Under the action of the Lorentz force, the charged molten slag particles generated during the cutting process will be affected by the Lorentz force. According to the left-hand rule, the charged particles will move along a specific direction, thus changing their movement trajectories, making it easier for the molten slag to be discharged from the cutting area, and also improving the cutting accuracy. The constraint effect of the magnetic field on the charged particles can make the plasma in the cutting area more stable. During the laser cutting process, the stability of the plasma has an important impact on the transmission and absorption of the laser. A stable plasma can reduce the scattering and energy loss of the laser, enabling the laser to act more accurately on the cutting part, thereby improving the cutting accuracy. The Lorentz force can affect the fluid flow in the molten pool, making the heat distribution in the molten pool more uniform and reducing local overheating. This helps to suppress the expansion of the heat-affected zone and reduce the thermal deformation of the material during cutting, further improving the cutting accuracy and efficiency.

[0042] The rear magnetic plate 17 can play a role in constraining the moving charged particles, making them move along a specific trajectory. This is because the direction of the Lorentz force of the magnetic field on the charged particles is related to the movement direction of the particles and the magnetic field direction. The magnetic field generated by the trapezoidal magnetic plate can, to a certain extent, guide the particles towards the expected direction and can guide the charged particles in the plasma to flow towards the electrode, improving the magnetic field efficiency.

[0043] During laser cutting, a heat zone will be generated. If the heat zone is not processed in a timely manner, it may lead to uneven distribution of laser energy in the cutting area, resulting in local overheating of the material. The material in the overheated area will be overly melted, and the melted material, under the action of surface tension and gravity, cannot be blown away from the cutting area by the auxiliary gas in a timely manner, and will form molten slag adhering to the cutting edge or the cutting surface. In the prior art, a straight-mouth purging device is installed at the nozzle 14 to form a direct impact air flow to purge the molten slag. At the beginning stage of cutting, when the amount of hot molten slag is small, the direct impact air flow can effectively blow away the molten slag and keep the cutting area clean. However, when the heat in the heat zone increases, the cleaning ability of the direct impact air flow for the molten slag will decrease significantly.

[0044] When the device cools down the heat zone, the air flow will flow along the spiral air duct 20. When the air flow passes through the spiral air duct 20, it will form a spiral flow trajectory, ensuring the stability of the air flow output. At this time, the air flow will output to the right along the side air groove 21 (taking Figure 8(for example), a part of the air flow will enter the inner air duct 29 and then enter the outer air duct 30. The outer air duct 30 communicates with the outer ring 26, and the outer ring 26 also communicates with the inner ring 25. When the air flow passing through the side air groove 21 contacts the spoiler 22, the spoiler 22 will obstruct the air flow to form a turbulent flow and output it towards the outer ring 26. An inclined inner flow port 27 is provided in the inner ring 25, and the opening direction of the inner flow port 27 is to the right to output the air flow to the right, accelerating the air flow speed. The outer flow port 28 is provided on the outer ring 26, and the outer flow port 28 conveys the air flow inward to make the pushed air flow form a rotational turbulent flow. A rotating ball 23 is provided outside the inner ring 25, and an electric shaft 24 is provided outside the rotating ball 23 to drive the angle adjustment of the inner ring 25 and the outer ring 26.

[0045] When two rotational turbulent flows collide, their momenta are superimposed on each other to generate a stronger impact force. This impact force can effectively act on the slag, causing it to fall off from the cutting surface or other attachment parts. Compared with the air flow or turbulent flow in a single direction, the colliding rotational turbulent flows can impact the slag from different angles, more comprehensively cover the area where the slag is located, and improve the cleaning effect. In this flow field, the direction and speed of the air flow are constantly changing, generating various vortex and turbulent flow regions. The colliding air flow generates three-dimensional rotational vortices, the size of which can reach 2 - 5 times the diameter of the nozzle 14, while the vortices of the straight air flow are mainly longitudinal turbulent flows, the air flow energy is concentrated in the cutting direction, and the lateral diffusion is weak. This complex flow field of the colliding air flow can make the slag be affected by forces in multiple directions, increasing the movement and tumbling of the slag and making it easier to detach from the object surface. At the same time, the vortices in the flow field can entrain the slag into them and carry it away with the air flow, preventing the slag from adhering to the cutting surface again, and their interaction will increase the speed and turbulence intensity of the air flow, which helps to improve the slag-carrying capacity of the air flow, thus achieving a better cleaning effect.

[0046] In the existing heat dissipation, the action range of the direct air flow is relatively narrow, and it is easy to form an uneven heat dissipation situation on the hot zone surface. Moreover, due to the limited coverage area of the direct air flow on the hot zone surface, for a large-area hot zone, its overall heat dissipation effect may be inferior to that of the rotational turbulent flow collision or the ordinary colliding air flow. In addition, the direct air flow may form a large pressure difference on the hot zone surface, resulting in the air flow forming a backflow around the hot zone, affecting the heat dissipation effect. The complex three-dimensional flow field formed during the rotational turbulent flow collision can make the contact between the air and the hot zone surface more sufficient, increasing the heat transfer area and disturbance degree between the air and the hot zone. This helps to break the thermal boundary layer and make the heat more effectively transfer from the hot zone to the air, thereby improving the heat dissipation effect.

[0047] After purging, some of the molten slag may be purged to the bottom of the material plate. At this time, the electric scraper 11 extends and retracts to a suitable position, and follows the second electric chute 9 to scrape off the attached molten slag. The electric scraper 11 will scrape off the molten slag following the laser cutting and scrape it off in the first time. Therefore, electric scrapers 11 are provided on both sides of the electric slider 10, and scraping can be performed both front and back.

[0048] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
