Description

Technical Field

[0001] The invention relates to the technical field of laser cutting equipment, and in particular to a laser cutting workbench for sheet metal processing. Background Art

[0002] Laser cutting technology has become an indispensable part of modern manufacturing and is widely used in sheet metal processing, automobile manufacturing, aerospace, electronic appliances, and machinery manufacturing. As an important part of the laser cutting system, the laser cutting table directly affects the accuracy, efficiency, and quality of the cutting process. Laser cutting is a processing technology that uses a high-power laser beam to irradiate the surface of the material, rapidly heating it to the melting point or boiling point, and then blows away the molten or vaporized material through airflow to achieve cutting.

[0003] In the field of sheet metal processing, splitting a long plate into multiple short plates of equal length is a common process, which is widely used in manufacturing, construction, home appliances and other industries. This segmented cutting technology not only improves material utilization, but also simplifies subsequent processing steps and improves production efficiency. Segmented cutting can simplify the production process, reduce the number of handling and positioning, and improve production efficiency.

[0004] The laser cutting equipment in the prior art usually sets a water spray system near the laser cutting head when cutting sheet metal plates. The water spray system moves with the laser cutting head to cool the cutting path. However, when the laser beam penetrates the sheet metal plate, the material quickly melts and partially vaporizes at high temperature to form molten metal droplets and metal vapor. When the laser beam penetrates the plate, these high-temperature molten materials will spray out from the cutting seam to produce a large number of sparks. The sparks contain a large number of tiny metal particles and smoke, which will adhere to the cutting platform and sheet metal parts. There is no good solution for this in the prior art. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a laser cutting workbench for sheet metal processing, which aims to at least alleviate to a certain extent the problem in the prior art that sparks and tiny metal particles are attached to the workbench when the laser beam penetrates the sheet metal plate during the laser cutting process.

Through the set moving parts, the box moves to the bottom of the sheet metal during the laser cutting process, forming a closed space, which effectively absorbs the heat generated when the laser penetrates the sheet metal. The liquid in the box can capture sparks and molten metal, preventing sparks from flying and molten metal from spreading, and further cools the cutting area, reducing the heat-affected zone and improving the cutting quality.

[0028] Secondly, the design of the present invention does not require an additional spray source, avoiding the negative impact of the water spray system on the stability of the sheet metal plate. The top of the box body contacts the bottom of the sheet metal plate to form a closed box, which effectively prevents the diffusion of the metal solution, reduces the contamination of the cutting platform, and reduces the complexity of cleaning and maintenance work. At the same time, the design can ensure the stability of the cutting work during the process of cutting, cooling and capturing the molten metal.

[0029] In addition, after the cutting work is completed, the box body can be reset to the initial position, and the liquid in the box body can exchange heat with the liquid in the cutting table, while releasing the metal debris in the box body to facilitate the next cutting work. Through the design of the mobile frame and the conveyor shaft, the cut sheet metal can be automatically conveyed away from the cutting table, realizing the purpose of automatic unloading.

[0030] In summary, the present invention provides a more efficient, safe and environmentally friendly cutting solution by improving traditional laser cutting equipment. The design significantly improves the cutting quality, cooling effect and safety of the working environment, simplifies the cleaning and maintenance of the equipment, and improves the overall production efficiency.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] refer to Figure 1-Figure 10 , a laser cutting workbench for sheet metal processing, comprising:

[0048] A cutting platform 100, on which a cutting table 101 is provided;

[0049] A plurality of thorn plates 102 provided on the cutting table 101 are used to increase the friction between the sheet metal plate and the cutting table 101;

[0050] A moving frame 103 is disposed on the cutting table 101, and a plurality of conveying shafts 104 are disposed on the moving frame 103;

[0051] A laser cutting head 105 disposed on the cutting platform 100;

[0052] A box body 106 is disposed in the cutting platform 100, and the box body 106 is located lower than the thorn plate 102 and the moving frame 103;

[0053] A driving component disposed between the cutting platform 100 and the laser cutting head 105, used to move the laser cutting head 105 laterally, and the driving component can move the laser cutting head 105 longitudinally downward when moving the laser cutting head 105 to a preset position;

[0054] A moving component disposed between the cutting platform 100 and the box body 106, used to move the box body 106 upward when the laser cutting head 105 moves downward to a preset position, and to close the bottom of the box body 106 when the box body 106 moves upward to the preset position;

[0055] The box body 106 can move the position of the movable frame 103 when it moves upward to a preset position, and the movable frame 103 can rotate the conveying shaft 104 when it returns to the initial position, and the conveying shaft 104 rotates clockwise;

[0056] By setting up the cutting table 101, the operator can pour cleaning liquid into the cutting table 101, and can place the sheet metal plate that needs to be laser cut on the cutting table 101. The sheet metal plate is received by the provided thorn plate 102 and the conveying shaft 104 on the movable frame 103. When in use, the part that needs to be cut can be aligned with the position of the laser cutting head 105. When cutting, the operator can turn on the driving component, and the driving component can move the position of the laser cutting head 105 laterally. When the laser cutting head 105 moves to the preset position, it can move downward longitudinally to be closer to the sheet metal plate. When the position of the laser cutting head 105 reaches the position of the sheet metal plate, the laser cutting head 105 is turned on, and the laser beam emitted by the laser cutting head 105 can cut the sheet metal plate. Cutting, let the laser cutting head 105 move downward a distance when it moves to the preset position, so that the laser cutting head 105 can be closer to the surface of the sheet, reducing the scattering and deviation of the laser beam, ensuring the accuracy of cutting and edge finish. In addition, when the laser cutting head 105 moves downward, the movable component set can move the position of the box body 106 upward, and the box body 106 can move the movable frame 103 when it moves upward to the preset position, so that the movable frame 103 can do an evasive action, providing the box body 106 to move to the space between the thorn plate 102 group and the movable frame 103, and the box body 106 can move to the bottom of the sheet metal plate and contact with the bottom of the sheet metal plate. At the same time, when the box body 106 moves upward to the preset position, it can also close the bottom of the box body 106, on the cutting table When 101 is filled with clean liquid, after the bottom of the box body 106 is closed, the box body 106 can be filled with liquid. When the laser beam penetrates the sheet metal plate, it can hit the liquid in the box body 106 and form splashes. Through this design, the liquid in the box body 106 can effectively absorb the heat generated when the laser penetrates the sheet metal plate. For the sparks formed at the bottom of the sheet metal plate when the laser beam penetrates the sheet metal plate, the splashed liquid can capture the sparks to prevent the sparks from splashing and the diffusion of molten metal. At the same time, the liquid in the box body 106 can further cool the cutting area, reduce the heat-affected zone, and improve the cutting quality. The box body 106 can effectively collect and process sparks and molten materials when working, maintain the cleanliness of the cutting platform 100, and improve the working efficiency.

Compared with the prior art in which a spray mechanism is provided at the bottom of the sheet metal, the present application does not require an additional spray source, and will not affect the normal cutting of the laser beam during the cooling and spark catching process. The top of the box body 106 is in contact with the bottom of the sheet metal plate, which enables the box body 106 to form a closed box, which can effectively prevent the diffusion of the metal solution, reduce the pollution of the cutting platform 100, and reduce the complexity of cleaning and maintenance work. In addition, compared with the water spray mechanism, the sprayed water flow will not affect the stability of the sheet metal plate, which can ensure the stability of the cutting work during the cutting, cooling, and catching of the molten metal. Furthermore, after the cutting work is completed, the position of the box body 106 can be reset downward.When the box body 106 is reset downward to the initial position, the bottom of the box body 106 is opened, allowing the liquid in the box body 106 to exchange heat with the liquid in the cutting table 101, and at the same time releasing the metal debris in the box body 106 to facilitate the next cutting work. During the process of the box body 106 being reset downward, the movable frame 103 is reset to the initial position. During this process, the multiple conveying shafts 104 thereon rotate clockwise, and can convey the cut section of sheet metal away from the cutting table 101, thereby achieving the purpose of automatic unloading. The present invention improves the design of traditional laser cutting equipment, adds a box body 106 and a liquid cooling system, solves the problem of spark and molten metal diffusion during laser cutting, and significantly improves the cutting quality and the safety of the working environment. This design not only enhances the cutting accuracy and cooling effect, but also simplifies the cleaning and maintenance of the equipment, and improves the overall production efficiency. Compared with the prior art, the present invention has obvious advantages and can bring more efficient, safe and environmentally friendly cutting solutions to the sheet metal processing industry. ,

The rotation of the rotating shaft 200 can move the box body 106 upward through the first gear 201 and the first rack 202 with a different gear ratio from the second gear 203, thereby achieving the purpose of moving the box body 106 to the bottom of the sheet metal plate and contacting the bottom of the sheet metal plate.
