Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal manufacturing, and specifically relates to a cutting device for sheet metal manufacturing. Background Technique

[0002] Sheet metal manufacturing is a comprehensive cold working process for metal sheets, which covers a variety of technical means such as shearing, punching / cutting / combining, folding, welding, riveting, splicing, stretching, and forming. The main feature of this process is that through this series of operations, the thickness of the final obtained parts remains consistent. During the sheet metal manufacturing process, it is often necessary to utilize the mechanical properties of metals, such as elasticity, stiffness, strength, plasticity, hardness, etc. These properties are extremely important indicators for measuring material properties and are crucial for achieving precise and efficient sheet metal processing. At the same time, according to the design requirements of the product, sheet metal manufacturing also needs to consider the processability of parts, that is, the difficulty of parts in punching, bending, and stretching processes, to ensure less material consumption, fewer process steps, simple die structure, high service life, and stable product quality.

When the cutting table moves linearly forward and backward, it will synchronously drive the metal plate magnetically adsorbed and positioned by the supported magnetic column to move linearly forward and backward for adjustment, so as to facilitate the left and right and forward and backward linear movement adjustment of the cutting position of the metal plate while performing laser cutting on the metal plate;

[0016] When the metal plate is of a special-shaped structure in the present utility model, by placing the metal plate with a special-shaped structure on the upper end of the supported magnetic column, when the metal plate with a special-shaped structure is placed on the upper end of the supported magnetic column, the convex part of the metal plate with a special-shaped structure will downwardly press the supported magnetic column. When the supported magnetic column is downwardly pressed, it will linearly move downward and contract along the inner wall of the fixed tube. When the supported magnetic column linearly moves downward and contracts, it will push the compression support spring. When the support spring is pushed and compressed, it will reversely push the supported magnetic column through the elastic potential energy generated by its own compression deformation, so that while the supported magnetic column linearly moves downward and contracts, the upper end of the supported magnetic column always maintains magnetic adsorption with the metal plate with a special-shaped structure, thus realizing the function of facilitating magnetic adsorption and positioning of the metal plate with a special-shaped structure.

A second screw nut 10 is threadedly connected to the middle outer surface of the second transmission screw rod 9, and a cutting table 12 is fixedly installed at the upper end of the second screw nut 10. The two sides of the lower end of the cutting table 12 penetrate and are in fitting and movable connection with second limit slide bars 13, and the number of the second limit slide bars 13 is two, which are symmetrically distributed on the two sides of the lower end of the cutting table 12 respectively. The front and rear ends of the second limit slide bars 13 are respectively fixedly installed on the two sides of the front and rear ends of the moving frame 4. A support table 14 is fixedly installed in the middle of the cutting table 12, a fixed pipe 15 is fixedly installed through the middle of the support table 14, and the number of the fixed pipes 15 is several, which are symmetrically distributed in sequence in the middle of the support table 14. A support spring 16 is fixedly installed at the inner bottom of the fixed pipe 15, and a support magnetic column 17 for supporting the metal sheet is fixedly installed at the upper end of the support spring 16. The lower outer surface of the support magnetic column 17 is in fitting and movable connection with the inner wall of the upper end of the fixed pipe 15, so that the support magnetic column 17 is elastically supported by the cooperation of the support spring 16 and the fixed pipe 15;

[0023] A third driving motor 19 is fixedly installed on the front side of the upper end of the support top frame 2, a third transmission screw rod 20 is fixedly installed on the lower end transmission shaft part of the third driving motor 19, and the upper and lower ends of the third transmission screw rod 20 are rotatably connected to the upper and lower ends of the middle part of the support top frame 2 through bearings. A third screw nut 21 is threadedly connected to the middle outer surface of the third transmission screw rod 20, and an L-shaped mounting plate 22 is fixedly installed at the front end of the third screw nut 21. The two sides of the rear end of the L-shaped mounting plate 22 penetrate and are in fitting and movable connection with third limit slide bars 11, and the number of the third limit slide bars 11 is two, which are symmetrically distributed on the two sides of the rear end of the L-shaped mounting plate 22 respectively.

A laser cutting gun 18 for cutting the metal sheet is fixedly installed on the front side of the lower end of the L-shaped mounting plate 22.

[0024] Working principle: During use, the utility model places the metal plate to be cut on the upper end of the supporting magnetic column 17. When the metal plate is placed on the upper end of the supporting magnetic column 17, the supporting magnetic column 17 magnetically adsorbs and positions the metal plate. When the supporting magnetic column 17 magnetically adsorbs and positions the metal plate, the laser cutting gun 18 can be controlled to be turned on to perform laser cutting on the metal plate. When the laser cutting gun 18 performs laser cutting on the metal plate, the third driving motor 19 is controlled to be turned on. When the third driving motor 19 is turned on, it drives the third transmission lead screw 20 to rotate. When the third transmission lead screw 20 rotates, it drives the third lead screw nut 21 to move up and down due to the acting force generated by the threaded connection with the middle outer curved surface of the third transmission lead screw 20. When the third lead screw nut 21 moves up and down, it drives the L-shaped mounting plate 22 to move linearly up and down. When the L-shaped mounting plate 22 moves linearly up and down, it drives the laser cutting gun 18 to move linearly up and down for adjustment, so as to realize that while performing laser cutting on the metal plate, the distance between the laser cutting gun 18 and the metal plate can be adjusted linearly up and down;

[0025] By controlling the first driving motor 5 to be turned on, when the first driving motor 5 is turned on, it drives the first transmission lead screw 6 to rotate. When the first transmission lead screw 6 rotates, it drives the first lead screw nut 7 to move left and right due to the acting force generated by the threaded connection with the middle outer curved surface of the first transmission lead screw 6. When the first lead screw nut 7 moves left and right, it drives the moving frame 4 to move linearly left and right. When the moving frame 4 moves linearly left and right, it synchronously drives the metal plate magnetically adsorbed and positioned by the supporting magnetic column 17 to move linearly left and right for adjustment. When the second driving motor 8 is controlled to be turned on, the second driving motor 8 drives the second transmission lead screw 9 to rotate. When the second transmission lead screw 9 rotates, it drives the second lead screw nut 10 to move back and forth due to the acting force generated by the threaded connection with the middle outer curved surface of the second transmission lead screw 9. When the second lead screw nut 10 moves back and forth, it drives the cutting table 12 to move linearly back and forth. When the cutting table 12 moves linearly back and forth, it synchronously drives the metal plate magnetically adsorbed and positioned by the supporting magnetic column 17 to move linearly back and forth for adjustment, so as to realize that while performing laser cutting on the metal plate, it is convenient to adjust the cutting position of the metal plate linearly left and right and back and forth;

[0026] Meanwhile, when the metal sheet has a special-shaped structure, by placing the metal sheet with the special-shaped structure on the upper end of the supporting magnetic column 17, when the metal sheet with the special-shaped structure is placed on the upper end of the supporting magnetic column 17, the protruding part of the metal sheet with the special-shaped structure will squeeze the supporting magnetic column 17 downward. When the supporting magnetic column 17 is squeezed downward, it will move linearly downward and contract along the inner wall of the fixed tube 15. When the supporting magnetic column 17 moves linearly downward and contracts, it will push the compression supporting spring 16. When the supporting spring 16 is pushed and compressed, it will reversely push the supporting magnetic column 17 through the elastic potential energy generated by its own compression deformation, so that while the supporting magnetic column 17 moves linearly downward and contracts, the upper end of the supporting magnetic column 17 always maintains magnetic adsorption with the metal sheet with the special-shaped structure, thus realizing the function of facilitating magnetic adsorption and positioning of the metal sheet with the special-shaped structure.
