[0023] 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.

[0024] Please see Figures 1-5 This utility model provides a technical solution: a cutting device for processing metal products for fire protection, including: a base plate 1 and a sliding worktable 3. The base plate 1 provides a stable support surface, ensuring that all components can be firmly installed on it and maintaining the overall stability of the device.

[0025] The base plate 1 has slide rails 2 on both sides of its top, and a sliding worktable 3 is mounted on top of the slide rails 2. A rack 12 is mounted on one side of the outer wall of the sliding worktable 3, and a servo motor 13 is mounted on one side of the top of the base plate 1. A gear 14 is fixed to the top of the output shaft of the servo motor 13, and the gear 14 meshes with the rack 12. The servo motor 13 serves as the power source, providing precise speed and position control. The rotation of its output shaft drives the gear 14 to mesh with the rack 12, achieving precise movement of the sliding worktable 3 and ensuring cutting accuracy and efficiency. The gear 14 meshes with the rack 12, converting the rotational motion of the servo motor 13 into linear motion of the sliding worktable 3. The precise meshing of the gear 14 ensures the stability and accuracy of the worktable during movement.

[0026] A vertical plate 7 is located in the middle of one side of the base plate 1. A Z-axis linear motor 8 is located on one side of the vertical plate 7. A lifting plate 9 is located on one side of the Z-axis linear motor 8. A cutting drive motor 10 is located on the bottom side of the lifting plate 9. A cutting saw blade 11 is fixed to one end of the output shaft of the cutting drive motor 10. The lifting plate 9 is connected to the Z-axis linear motor 8 and is used to support the cutting drive motor 10 and the cutting saw blade 11. Driven by the Z-axis linear motor, the lifting plate can move up and down in the vertical direction, thereby driving the cutting saw blade to perform cutting operations. The cutting drive motor 10 provides power to the cutting saw blade 11, enabling it to rotate at high speed. Driven by the motor, the cutting saw blade can cut metal plates, realizing the cutting operation.

[0027] The sliding worktable 3 has L-shaped positioning strips 4 on both sides of its top. These L-shaped positioning strips 4 are installed in an inverted L-shape on the sliding worktable 3. A locking screw 5 is located at the top of each L-shaped positioning strip 4, used to secure the metal sheet. The sides of the L-shaped positioning strips contact the metal sheet, thus positioning it from both sides and ensuring it remains in the correct position during cutting. The locking screw 5, installed at the top of the L-shaped positioning strips, securely fixes the metal sheet to the sliding worktable. Once the metal sheet is placed between the L-shaped positioning strips and adjusted to the correct position, the locking screw can be tightened, ensuring its bottom is in close contact with the metal sheet and providing sufficient clamping force. The design of the locking screw allows users to adjust it according to the thickness and size of the metal sheet, ensuring that the metal sheet does not move or shift during cutting.

[0028] The L-shaped positioning strip 4 has a fixing bolt 16 at its bottom, and is fixed to the sliding worktable 3 by the fixing bolt 16. A slot 6 is formed inside the sliding worktable 3 outside the fixing bolt 16. The design of the slot 6 allows for greater flexibility in the installation and adjustment of the fixing bolt. When the position of the L-shaped positioning strip needs to be adjusted, the fixing bolt can be loosened, the positioning strip moved along the slot, and finally the fixing bolt tightened again to fix the new position. This design not only improves the flexibility and adaptability of the equipment but also facilitates user operation and maintenance.

[0029] A rectangular groove is formed in the center of the sliding worktable 3, and guide rollers 15 are positioned between the two sides of the rectangular groove. The top surface of the guide rollers 15 is flush with the top surface of the sliding worktable 3. This design allows the metal sheet to roll smoothly on the guide rollers when placed, thereby reducing direct friction with the worktable surface and improving the smoothness and efficiency of the metal sheet's movement. The guide rollers are typically made of wear-resistant and corrosion-resistant materials to ensure their long-term stability and reliability.

[0030] A groove is formed in the middle of the guide roller 15, below the cutting saw blade 11, to allow the cutting saw blade 11 to pass. Grooves are also provided at both ends of the top of the sliding worktable 3. The width and depth of the grooves are precisely calculated to ensure that the cutting saw blade can pass completely through without colliding with the guide roller. This design not only improves the safety of the cutting operation but also ensures the continuity and stability of the cutting process. The presence of the grooves ensures that the cutting saw blade will not collide or rub against the top of the worktable during its descent, thus protecting the worktable and the cutting saw blade from damage. At the same time, the groove design makes the cutting process smoother and more stable, improving cutting quality and efficiency.

[0031] The top of the L-shaped positioning strip 4 has several threaded through holes at the connection point of the locking screws 5, arranged equidistantly on the L-shaped positioning strip 4. Limiting plates are located at both ends of the slide rail 2 on the top of the base plate 1. The equidistant arrangement of the threaded through holes on the L-shaped positioning strip not only ensures that the locking screws are evenly distributed and fixed on the positioning strip, but also improves the stability and reliability of the locking mechanism. When the locking screws are screwed into the threaded through holes, they firmly grip the metal plate, preventing it from shifting or moving during cutting. When the sliding worktable moves along the slide rail, the limiting plates prevent it from exceeding a predetermined range, thus preventing collisions and damage to other parts of the equipment.

[0032] When cutting sheet metal products using a fire-fighting metal product processing cutting equipment, the guide roller 15 rolls the metal sheet onto the sliding worktable 3. According to the set cutting dimensions, the position of the L-shaped positioning strip 4 on the sliding worktable 3 is adjusted, ensuring that both sides of the metal sheet abut against the L-shaped positioning strip 4. Then, by rotating the locking screw 5, the bottom of the locking screw 5 abuts against the metal sheet, fixing the metal sheet onto the sliding worktable 3. During cutting, the cutting drive motor 10 drives the cutting saw blade 11 to rotate. The Z-axis linear motor 8 drives the cutting saw blade 11 to rise and fall to control the cutting depth. The servo motor 13 drives the gear 14 to rotate. Through the cooperation of the gear 14 and the rack 12, the sliding worktable 3 moves horizontally on the slide rail 2 to achieve the cutting of the metal plate. When the metal plate is being cut, the sliding worktable 3 is used to feed and discharge the metal plate. The feeding and discharging of the metal plate is smoother. When cutting a thicker metal plate, it is not possible to cut it in one go. This facilitates the reciprocating feeding and discharging of the metal plate for cutting without the need for repeated positioning, thus ensuring the accuracy of the cutting.

[0033] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
