Description

Technical Field

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

[0002] A laser cutting machine is a high-tech cutting device that uses the high energy density of a laser beam to cut materials. The working principle involves focusing the laser emitted from a laser source into a high-power-density laser beam through an optical path system. This laser beam irradiates the workpiece surface, causing it to reach its melting or boiling point. Simultaneously, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a kerf is eventually formed in the material, thus achieving the cutting purpose.

[0003] Existing laser cutting machines are typically used in conjunction with gantry slides, which can be connected to CNC devices to adjust the cutting direction, thereby cutting metal sheets into the required shapes according to usage needs.

[0004] However, in the operation of existing laser cutting machines, the laser cutting head is usually located directly above the material, so it can only cut from the top surface of the material. If it is necessary to cut from other sides, the material needs to be flipped over, which is inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing laser cutting machines cannot perform multi-faceted cutting, and to propose a laser cutting device for metal processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laser cutting device for metal processing includes an operating table, which includes a panel with a circular hole.

[0008] To facilitate the rotation of the ring, preferably, the outer ring of the ring is fitted with a bearing, and the ring is rotatably connected to the inner ring of the circular hole through the bearing, while the outer ring of the bearing is fixedly connected to the inner ring of the circular hole.

[0009] To facilitate the rotation of the ring by the gear and gear ring, preferably, the bottom of the ring extends to the bottom of the panel, the gear ring and gear are both located below the panel and have a gap with the bottom of the panel, and the top of the first rotating shaft passes through the gear and is rotatably connected to the bottom of the panel.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example:

[0030] Reference Figures 1-7A laser cutting device for metal processing includes an operating table 1, which includes a panel 101 with a circular hole 102. The operating table also includes a circular ring 104 rotatably disposed within the circular hole 102, wherein a gear ring 105 is fitted around the outer ring 104, and the gear ring 105 meshes with a gear 106. The shaft of the gear 106 is fixedly connected to the power output shaft of a first stepper motor 108 via a first rotating shaft 107. A cutting mechanism 2 is disposed on the circular ring 104, allowing the first stepper motor 105 to drive the circular ring 104 to rotate via the transmission action of the gear 102 and the gear ring 105, which in turn drives the cutting mechanism 2 mounted thereon to rotate. The cutting mechanism 2 includes a semi-circular arc bracket 201, the two ends of which are fixedly mounted on the circular ring via a base 202. On ring 104, a laser cutting head 209 is slidably mounted on a semi-circular support 201. This allows the laser cutting head 209 to not only follow the rotation of the ring 104 as part of the cutting mechanism 2, but also to move along an arc-shaped trajectory along the semi-circular support 201, thereby achieving multi-angle and multi-directional cutting. A cutting table 3 is located at the center of the ring 104. The cutting table 3 includes a hollow column 301, with a frame 303 fixedly mounted on the top of the hollow column 301. A worktable 304 is fixedly mounted on the frame 303. A cleaning port 302 is provided at the bottom of the side wall of the hollow column 301. The worktable of the laser cutting machine is generally composed of multiple sets of racks with gaps between them. Dust generated during the cutting process falls through the gaps and can be collected by the hollow column 301 and cleaned through the cleaning port 302.

[0031] Furthermore, referring to Figure 2 and Figure 3 The ring 104 is rotatably connected to the inner ring of the circular hole 102 via the bearing 103, which can reduce the friction generated during rotation and make the ring 104 rotate more smoothly. The outer ring of the bearing 103 is fixedly connected to the inner ring of the circular hole 102. The bottom of the ring 104 extends to the bottom of the panel 101. The gear ring 105 and the gear 106 are both located below the panel 101 and have a gap with the bottom of the panel 101. The top end of the first rotating shaft 107 passes through the gear 106 and is rotatably connected to the bottom of the panel 101 to prevent contact with the panel 101 and thus prevent resistance to the rotation of the ring 104.

[0032] In addition, pulleys 204 are slidably connected to both sides of the semi-circular arc bracket 201 via semi-circular arc slide rails 203. A laser cutting head 209 is mounted below the two pulleys 204 via a base plate 207, with the laser head of the laser cutting head 209 pointing towards the center of the semi-circular arc bracket 201. A roller 210 is rotatably mounted on the base plate 207, and the roller 210 is in close contact with the inner ring of the semi-circular arc bracket 201. When the roller 210 is stationary, the pressure between the two prevents the pulleys 204 from sliding along the semi-circular arc slide rails 203. The second rotating shaft 211 moves along the support 208 and is fixedly connected to the first bevel gear 212. The first bevel gear 212 meshes with the second bevel gear 213. The bottom of the second bevel gear 213 is fixedly connected to the power output shaft of the second stepper motor 215 through the third rotating shaft 214. Therefore, when the second stepper motor 215 is started, the roller 210 can be driven to rotate through the transmission of the two bevel gears. The roller 210 and the two pulleys 204 can drive the laser cutting head 209 to move along the trajectory of the semi-circular slide rail 203.

[0033] Its working principle is as follows: The second stepper motor 215 is started. The second stepper motor 215 drives the roller 210 to rotate through the transmission action of the second bevel gear 213 and the first bevel gear 212. Since the roller 210 is tightly fitted to the inner ring of the semi-circular slide rail 203, when the roller 210 rotates, the laser cutting head 209 will move synchronously with the roller 210 and the two pulleys 204. Because the pulleys 204 slide along the trajectory of the semi-circular slide rail 203, the overall movement trajectory of the laser cutting head 209 on the semi-circular bracket 201 is also semi-circular. The first stepper motor 108 is started. The first stepper motor 108 connects to the gear ring 1 through the mounting base 109. The transmission action of 05 drives the ring 104 to rotate, causing the entire cutting mechanism 2 to rotate synchronously around the center of the ring 104, which in turn drives the laser cutting head 209 to move in a ring. The two movement trajectories are combined, so the laser beam of the laser cutting head 209 can cut at any angle above the worktable 304, thus achieving multi-angle and multi-directional cutting, which is more convenient to use. At the same time, the two movement trajectories can be combined to create a variety of movement lines, and the laser beam of the laser cutting head 209 can also cut at different tilt angles. Therefore, in addition to cutting different shapes, it can also cut different bevels, making it more widely applicable.

[0034] The laser cutting device for metal processing in this utility model can be used with a CNC system, making the operation more intelligent and convenient. The CNC system is existing technology and will not be described in detail here.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
