Description

Technical Field

[0001] This utility model relates to the field of metal material processing equipment technology, and in particular to a laser cutting device for metal material processing. Background Technology

[0002] Laser cutting technology, with its advantages of high cutting precision, high efficiency, and small heat-affected zone, has been widely used in the field of metal material processing. During the laser cutting process, the metal material melts and partially vaporizes under the action of high-energy laser. The incompletely vaporized molten metal drips onto the support plate that supports the metal material in the form of slag. As the cutting operation continues, the slag gradually accumulates and solidifies on the surface of the support plate. This not only affects the support plate's stability in supporting the metal material, causing the material to shift during subsequent cutting and reducing cutting precision, but may also affect the heat conduction efficiency of laser cutting due to the heat insulation effect of the slag. It may even further fuse with the subsequently dripping slag to form a thicker layer of slag that is more difficult to clean, increasing the difficulty of equipment maintenance. Existing methods for cleaning slag from the support plate of laser cutting devices mainly involve manual hammering, sanding, or high-pressure air blowing. Manual cleaning is inefficient, labor-intensive, and difficult to ensure thorough cleaning. Sanding can easily cause wear to the surface of the support plate, shortening its service life. High-pressure air blowing can only remove some loose, fine slag and has limited effect on cleaning solidified and adhered slag, failing to fundamentally solve the problem of slag accumulation. Therefore, a laser cutting device for metal material processing is proposed. Utility Model Content

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Example

[0016] like Figures 1 to 5 As shown, the present invention proposes a laser cutting device for metal material processing, including a machine tool 1. The machine tool 1 is provided with a slag collection tank 16 and a slag guide plate 17. Both the slag collection tank 16 and the slag guide plate 17 are fixedly connected to the machine tool 1. Through the arrangement of the slag collection tank 16 and the slag guide plate 17, the slag collection tank 16 collects the molten slag that has fallen off the machine tool and then drops it into the slag guide plate 17 below the slag collection tank 16 through the slag discharge port at the bottom of the tank. The slag is then discharged from the machine tool 1 by the slag guide plate 17, thus avoiding the long-term accumulation of waste slag that affects the operation of the equipment. The top surface of the machine tool 1 is provided with a Y-axis drive mechanism 2, an X-axis drive mechanism 3 and a Z-axis drive mechanism 4. A laser cutting head 5 is provided on one side of the Z-axis drive mechanism 4. The Y-axis drive mechanism 2, the X-axis drive mechanism 3, the Z-axis drive mechanism 4 and the laser cutting head 5 are all mature technologies, so they will not be described in detail. The machine tool 1 is equipped with a fixed frame 6, which is fixedly connected to the machine tool 1. A support plate 7 is connected to the inner side of the fixed frame 6, which is also fixedly connected to the fixed frame 6. The support plate 7 is used to support the metal material to be cut. Two L-shaped mounting plates 8 are symmetrically arranged on the outer wall of the machine tool 1, which are fixedly connected to the machine tool 1. The L-shaped mounting plate 8 includes a horizontal plate 81 and a vertical plate 82. A wind-cooling component 9 is provided on the top surface of the horizontal plate 81. The L-shaped mounting plate 8 provides a mounting platform for the wind-cooling component 9 on the top surface, and at the same time can prevent the splashed high-temperature molten slag from rebounding onto the surface of the lifting component and affecting the use of the equipment. The wind-cooling component 9 includes a guide rail 91 and a rack 92 on the top surface of the horizontal plate 81, and both the guide rail 91 and the rack 92 are fixedly connected to the horizontal plate 81. Two guide rails 91 have a single U-shaped mounting bracket 93 slidably mounted on their top surfaces. The guide rails 91 provide linear guidance for the U-shaped mounting bracket 93, restricting its movement trajectory, ensuring straightness and stability during movement, reducing friction, and preventing the U-shaped mounting bracket 93 from shifting or jamming. The U-shaped mounting bracket 93 secures components such as the pressure tank 97, air duct 98, and drive motor 94. Through a sliding connection with the guide rail 91, it converts the power transmitted by the gear 96 and rack 92 into linear motion. The U-shaped design avoids the working area below. Drive motors 94 are located on opposite sides of the U-shaped mounting bracket 93. A connecting shaft 95 is connected to the output end of each drive motor 94, and a gear 96 is fixedly connected to the connecting shaft 95. The gear 96 meshes with the rack 92. The rotational motion of the drive motor 94, through its output end, is precisely transmitted to the gear 96 via the connecting shaft 95. The gear 96 meshes with the fixedly arranged rack 92, converting the rotational motion of the drive motor 94 into linear motion. The symmetrical arrangement of the two drive motors 94 further improves the stability of movement and load capacity, avoiding uneven loading caused by unilateral force application. A pressure tank 97 is fixedly connected to the top surface of the U-shaped mounting bracket 93. An air duct 98 is fixedly connected to the bottom surface of the U-shaped mounting bracket 93. Air supply pipes 99 are connected to both sides of the pressure tank 97, with one end of each pipe connected to the air duct 98. Through the arrangement of the pressure tank 97, air supply pipes 99, and air duct 98, the pressure tank 97 is connected to an external air source, and the air supply pipes 99 connect the pressure tank 97 to the air duct 98, stably delivering the compressed air stored in the pressure tank 97 to the air duct 98. The duct 98 distributes compressed air evenly to the target area to cool down the high-temperature molten slag adhering to the surface of the support frame 7, thereby accelerating the cooling of the molten slag and facilitating subsequent cleaning. A long plate 10 is provided on the inner side of the vertical plate 82, and the long plate 10 is fixedly connected to the vertical plate 82. Multiple sets of lifting components 11 are provided inside the machine tool 1. A second drive motor 12 is provided on the outer side of the vertical plate 82, and the second drive motor 12 is fixedly connected to the vertical plate 82. The output end of the second drive motor 12 is fixedly connected to one of the lifting components 11. The second drive motor 12 provides driving force to the lifting components 11. Each lifting assembly 11 includes a drive shaft 111 rotatably mounted on one side of the vertical plates 82 and a screw 112 mounted on the bottom surface of the horizontal plate 81. The drive shaft 111 is rotatably connected to the machine tool 1, and the top end of the screw 112 is rotatably connected to the horizontal plate 81. Both ends of the drive shaft 111 are equipped with sprockets 14, and the outer rings of the sprockets 14 are fitted with the same chain 15. Both ends of the drive shaft 111 are equipped with bevel gears 113, which are fixedly connected to the drive shaft 111. One end of the screw 112... A bevel gear 114 is connected through the long plate 10 and meshes with a bevel gear 113. The screw 112 is rotatably connected to the long plate 10. Two guide plates 115 are symmetrically arranged on the top surface of the long plate 10 and are fixedly connected to the long plate 10. A movable plate 116 is slidably arranged inside the guide plate 115. A sprocket 117 is rotatably arranged on the top surface of the movable plate 116. A chain 118 is sleeved on the outer ring of the sprocket 117. A rotating motor 119 is arranged on the bottom surface of one of the movable plates 116. The output end of the rotating motor 119 is fixedly connected to the first sprocket 117 via a connecting rod. Two scraper assemblies 13 are connected to the outside of the first chain 118. The drive shaft 111 is rotatably set between the two vertical plates 82, providing a fixed mounting reference for the second sprocket 14 and the first bevel gear 113 at both ends. The screw 112 is set between the bottom surface of the horizontal plate 81 and the long plate 10, with its top end rotatably connected to the horizontal plate 81. The middle section passes through the long plate 10 and connects to the second bevel gear 114. One end of one drive shaft 111 is connected to the second drive motor 14. The second sprocket 14 is fixed to both ends of the drive shaft 111. The second sprocket 14 on the same side is meshed with the same second chain 15. The first bevel gear 113 is fixed to the drive shaft 111, and the second bevel gear 114 is fixed to the screw 112, and the two mesh. Through the above settings, a single motor drives multiple sets of lifting assemblies 11. With the precise meshing of the bevel gear sets, the horizontal rotation power is converted into vertical rotation power, making the rotation of the screws 112 on both sides completely synchronized. The guide plate 115 restricts the sliding trajectory of the movable plate 116, providing linear guidance for the movable plate 116 and preventing deviation. The movable plate 116 is threadedly connected to the screw 112. The rotation of the screw 112 drives the movable plate 116 to rise or fall along the direction of the guide plate 115. A sprocket 117 is mounted on the top surface of the movable plate 116, and a rotary motor 119 is connected to the bottom surface. While the movable plate 116 moves, the components mounted on it can move synchronously, thereby realizing the lifting and lowering of the scraper assembly 13. The highest point of the lifting assembly 119 is when the scraper assembly 13 is flush with the top of the support plate 7. The rotary motor 119... 19 The drive sprocket 117 is rotated by the connecting rod, and the connected scraper assembly 13 is driven to move synchronously by the meshing chain 118. Each pair of scraper assemblies 13 are located on both sides of the support plate 7. The meshing transmission of the sprocket 117 and the chain 118 eliminates the risk of slippage compared to belt transmission. The motor drive plus chain transmission realizes the power automation of the scraper assembly 13 without manual operation. The symmetrical arrangement of the scraper assemblies 13 can clean both sides of the support plate 7 at the same time, eliminating the need to clean one side at a time, shortening the cleaning time and improving the cleaning efficiency. The scraper assembly 13 includes a ring frame 131 fixedly mounted on the outside of a chain 118. A rectangular guide plate 18 is provided on one side of the ring frame 131. The rectangular guide plate 18 is slidably connected to the guide plate 115. The rectangular guide plate 18 guides the ring frame 131, allowing it to move along the direction of the rectangular guide plate 18. This also prevents the scraper 133 from deviating due to the characteristics of the chain when scraping slag, thus avoiding scraping the slag instead of scraping it. The rectangular guide plate 18 provides rigid support for the scraper 133. Two fixing clips 132 are symmetrically mounted on the top surface of the ring frame 131 and are fixedly connected to the ring frame 131. The scraper 133 is mounted on the side of the fixing clips 132 that are close to each other and is fixedly connected to the fixing clips 132. The triangular shape of the fixing clips 132 provides stable support for the scraper 133 when it scrapes slag.

[0017] In this embodiment, after the laser cutting head 5 completes the laser cutting operation on the metal material on the support plate 7 under the coordinated drive of the Y-axis drive mechanism 2, X-axis drive mechanism 3, and Z-axis drive mechanism 4, the device will start the slag cleaning process, start the air cooling component 9, start the drive motor 94, drive the connecting shaft 95 to rotate, and drive the gear 96 to rotate. The gear 96 meshes with the rack 92 on the top surface of the horizontal plate 81, converting the rotational motion into linear motion, driving the U-shaped mounting bracket 93 to reciprocate linearly along the guide rail 91. At the same time, the compressed air in the pressure tank 97 is transported to the U-shaped mounting bracket 93 through the air supply pipe 99. The air duct 98 on the bottom surface of the mounting bracket 93 blows air evenly onto the surface of the support plate 7. After the air cooling is completed, the drive motor 12 of the lifting assembly 11 is started. The drive motor 12 drives the drive shaft 111 connected to it to rotate. The sprockets 14 at both ends of the drive shaft 111 achieve synchronous rotation of multiple drive shafts 111 through the chain 15. The bevel gear 113 on the drive shaft 111 meshes with the bevel gear 114 at the top of the screw 112, converting the horizontal rotational power into vertical rotational power, driving the screw 112 to rotate synchronously. The rotation of the screw 112 drives the moving plate 116, which is threadedly connected to the screw 112, to move vertically upward along the guide plate 115. The upward movement of the moving plate 116 drives the sprocket 117, the chain 118 and the chain 119 to rotate synchronously. The scraper assembly 13 connected to the outside of chain 118 is raised to a height flush with the top surface of the support plate 7. The rotating motor 119 on the bottom surface of the moving plate 116 is started. The output end of the rotating motor 119 drives the sprocket 117 to rotate through the connecting rod. The sprocket 117 drives the two sets of scraper assemblies 13 to move synchronously through chain 118. Under the transmission of chain 118, the scraper 133 of the scraper assembly 13 will simultaneously adhere to both sides of the support plate 7 and perform reciprocating scraping motion to scrape the solidified slag off the support plate 7. The slag scraped off by the scraper assembly 13 will fall directly into the slag collection tank 16 inside the machine tool 1. The slag in the slag collection tank 16 falls into the slag guide plate 17 below through the slag discharge port at the bottom of the tank, and finally is discharged from the machine tool 1 along the inclined guide plate 17.
