Description

Technical Field

[0001] This utility model relates to the field of laser cutting device technology, specifically a slag removal device for a laser cutting machine. Background Technology

[0002] With technological advancements, laser cutting technology has gradually replaced traditional processing methods, becoming an important processing tool in modern industrial manufacturing. The principle of laser cutting is as follows: a focused, high-power-density laser beam irradiates the workpiece, causing the material in the irradiated area to rapidly melt, vaporize, ablate, or reach its ignition point. Simultaneously, a high-speed airflow coaxial with the beam blows away the molten material, thus cutting the workpiece. However, during laser cutting, due to factors such as the characteristics of the workpiece material, spatter often adheres to the workpiece surface, affecting the quality of subsequent processing.

[0003] However, in the existing technology, the slag removal operation of the workpiece is mostly carried out by scraping the surface with a slag removal device after the machining is completed. Since the interval between the completion of machining and the slag removal operation is long, the molten slag cooling time exceeds 1 minute, which causes the molten slag to solidify and form a tight bond with the workpiece / table. The scraper needs to apply more force to scrape, which may lead to incomplete scraping; or even leave scratches on the workpiece surface, ultimately affecting the scraping effect and processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a slag removal device for laser cutting machines to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slag removal device for a laser cutting machine, comprising a worktable, a moving device on the worktable, a laser cutting device body mounted on the moving device via a mounting box, collection components symmetrically arranged on both sides of the mounting box, and a scraping mechanism located at the rear end of the laser cutting device body.

[0006] Preferably, in order to place and support the workpiece, facilitate air circulation, and facilitate the collection of waste and slag, toothed plates are equidistantly arranged on the worktable. The toothed plates are used to place and support the workpiece to be cut.

[0007] Preferably, in order to collect the slag on the surface of the workpiece uniformly and clean it in a timely manner after laser cutting, the collection component includes collection boxes symmetrically arranged on both sides of the mounting box, a collection pipe is provided under the collection box, and a collection cover matching the main body of the laser cutting device is provided under the collection pipe.

[0008] Preferably, in order to ensure the stability and firmness of the collection pipe, fixing rings are equidistantly sleeved on the outside of the collection pipe, and the fixing rings are fixedly connected to the side wall of the mounting box by fixing rods.

[0009] Preferably, in order to scrape off the surface after laser cutting, the slag is relatively soft and has weak adhesion within 10-30 seconds after cutting, so that the scraper can easily scrape it off and it is not easy to leave residue. The scraping mechanism includes a scraper that is inclinedly set under the mounting box. The scraper is equipped with a rotating rod through the mounting component. The two ends of the rotating rod are connected to the mounting box through the rotating component.

[0010] Preferably, in order to facilitate the installation and removal of the scraper and to facilitate regular cleaning or replacement, the installation component includes a mounting base located under the rotating rod, and the mounting base has a mounting groove that matches the scraper.

[0011] Preferably, in order to allow the scraper to better adhere to the workpiece and ensure the scraping effect, the rotating assembly includes rectangular plates symmetrically arranged under the mounting box. A rotating cavity is opened in the rectangular plate, and a rotating rod extends into the rotating cavity. The rotating rod is connected to the inner wall of the rotating cavity through a spiral spring.

[0012] Compared with the prior art, the beneficial effects of this utility model are: (1) The scraping mechanism is coaxially set with the main body of the laser cutting device and located at its rear end. It can scrape off the slag on the surface of the workpiece in time after cutting. At this time, the slag is relatively soft and has weak adhesion. The scraper can easily scrape it off and it is not easy to leave residue. This avoids the problem of the slag being tightly combined with the workpiece / table after cooling in the traditional method, which makes scraping difficult and leaves scratches. It improves the scraping effect and processing efficiency. The scraper is connected to the rotating rod through the mounting base. The mounting slot opened in the mounting base can realize the quick installation and disassembly of the scraper through bolts and other means, which is convenient for regular cleaning or replacement and ensures the continuity of the scraping effect. (2) The collection components symmetrically arranged on both sides of the mounting box include a collection box, a collection pipe and a collection cover that matches the main body of the laser cutting device. They can collect the scraped slag in a unified manner. Together with the collection hopper at the bottom of the workbench, they form a complete path from scraping to collection, ensuring that waste and slag do not remain on the workpiece and workbench surface, thus guaranteeing the quality of subsequent processing.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides an embodiment of a slag removal device for a laser cutting machine, including a worktable 11. A moving device 12 is provided on the worktable 11, and a laser cutting device body 15 is provided on the moving device 12 via a mounting box 14. The moving device 12 can be adjusted by means of a moving guide rail, a reciprocating lead screw, a linear motor, etc., to realize the three-axis movement of the laser cutting device body 15, which is convenient for cutting workpieces. This is a relatively mature technology and will not be described in detail here. The worktable 11 is provided with comb plates 13 at equal intervals. The comb plates 13 are used to place and support the workpiece to be cut. The sharp teeth of the comb plates only have a small amount of contact with the bottom of the workpiece, avoiding large areas of the table surface from blocking the laser. The spaced gaps can accommodate any movement trajectory of the laser. Even when cutting non-linear shapes such as circles and irregular shapes, the comb plates will not interfere with the laser beam path, eliminating the need for frequent adjustments to the table position. At the same time, the gaps can accelerate airflow and facilitate the falling of molten slag from the gaps. A corresponding collection hopper is provided at the bottom of the worktable 11 to facilitate the unified collection of waste and molten slag.

[0017] Please see Figures 1-4The mounting box 14 has symmetrically arranged collection components on both side walls, and a scraping mechanism is located at the rear end of the laser cutting device body 15. The collection components include collection boxes 21 symmetrically arranged on both side walls of the mounting box 14, collection pipes 22 below the collection boxes 21, and collection covers 23 matching the laser cutting device body 15 below the collection pipes 22. The collection boxes 21, collection pipes 22, and collection covers 23 work similarly to a vacuum cleaner, facilitating the collection of residual slag on the surface of the workpiece after cutting, ensuring slag removal efficiency. This is a relatively mature technology and will not be elaborated upon here. Fixing rings 24 are equidistantly sleeved on the outside of the collection pipes 22. The fixing rings 24 are fixedly connected to the side walls of the mounting box 14 via fixing rods 25, ensuring the stability and firmness of the collection pipes 22. The scraping mechanism includes a scraper 31 inclinedly arranged under the mounting box 14. The scraper 31 can scrape the surface after the workpiece is cut to remove residual slag, facilitating further processing by the collection components. The scraper 31 is equipped with a rotating rod 32 via an installation assembly. The rotating rod can rotate and tilt to better adhere to the workpiece surface and ensure scraping effect. The two ends of the rotating rod 32 are connected to the mounting box 14 via a rotating assembly. The installation assembly includes a mounting base 33 located under the rotating rod 32. The mounting base 33 has a mounting groove 34 that matches the scraper 31. It can be fixed by bolts or other means for easy installation and disassembly. The rotating assembly includes rectangular plates 35 symmetrically arranged under the mounting box 14. The rectangular plates 35 have a rotating cavity 36. The rotating rod 32 extends into the rotating cavity 36 and is connected to the inner wall of the rotating cavity 36 via a spiral spring 37. The spiral spring 37, in conjunction with the rotating rod 32, allows the scraper 31 to rotate and tilt to adhere to the workpiece surface for scraping. After moving upwards, it can be easily rotated back to its original position. When the scraper 31 contacts the workpiece, the cutting head of the laser cutting device body 15 maintains the optimal cutting distance from the workpiece. This is a relatively mature technology and will not be described in detail here.

[0018] Working Principle: In use, the workpiece to be processed is placed on the comb plate 13 on the worktable 11. Then, the moving device 12 works in conjunction with the main body 15 of the laser cutting device to perform a cutting operation on the workpiece. During the cutting process, as the main body 15 of the laser cutting device moves and cuts, the scraper 31 adheres to the workpiece. It rotates within the rotating cavity 36 in conjunction with the rotating rod 32 and the spiral spring 37. The spiral spring 37 deforms and stores potential energy, allowing the scraper 31 to better adhere to the workpiece. After cutting, as the moving device moves... The scraper 31 can scrape off the slag on the surface of the workpiece. At the same time, the scraped slag can be collected by the collection box 21, collection pipe 22 and collection cover 23. After the cutting is completed, the slag can be scraped and cleaned to ensure the cleanliness of the workpiece and the worktable 11 and not affect the subsequent processing. After the processing is completed, the moving device 12 works, moving and resetting the whole unit. The scraper 31 moves away from the workpiece. Under the action of the potential energy of the spiral spring 37, the rotating rod 32 rotates and resets in the rotating cavity 36, which facilitates the next cutting and scraping.
