Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to a laser cutting device for steel plate processing. Background Technique

[0002] Laser cutting is to emit a high-power density laser beam through a laser. After being focused by an optical system, a laser focus is formed. When the power density of the laser focus reaches or exceeds the thermal ignition point of the material to be cut, the material will quickly reach the melting point and evaporate to form a hole. At the same time, the high-pressure gas coaxial with the beam blows out the molten material to form a cut, thereby realizing the cutting of the material;

[0028] Working principle: When in use, the utility model places the steel plate to be laser cut on the upper end of the cutting support groove 7. When the steel plate is placed on the upper end of the cutting support groove 7, the first motor 4 is controlled to start. When the first motor 4 starts, it drives the first gear 5 to rotate. When the first gear 5 rotates, due to the acting force generated by the meshing connection between the side end of the first gear 5 and the first rack 6, the moving support plate 3 is driven to move linearly back and forth along the upper end of the first limit slide rail 2. When the moving support plate 3 moves linearly back and forth, it drives the steel plate placed on the upper end of the cutting support groove 7 to move linearly back and forth for adjustment. When the steel plate moves linearly back and forth for adjustment, the cutting position of the steel plate can be adjusted linearly back and forth;

[0029] When the steel plate moves linearly back and forth for adjustment, the second motor 11 is controlled to start. When the second motor 11 starts, it drives the second gear 12 to rotate. When the second gear 12 rotates, due to the acting force generated by the meshing connection between the side end of the second gear 12 and the second rack 13, the moving frame 10 is driven to move linearly left and right along the upper end of the second limit slide rail 9. When the moving frame 10 moves linearly left and right, it drives the moving plate 14 to move linearly left and right along the front end of the third limit slide rail 15. When the moving plate 14 moves linearly left and right, it synchronously drives the laser cutting head 24 to move linearly left and right for adjustment. By controlling the start of the third motor 18, when the third motor 18 starts, it drives the third gear 19 to rotate. When the third gear 19 rotates, due to the acting force generated by the meshing connection between the side end of the third gear 19 and the third rack 20, the mounting plate 17 is driven to move linearly up and down. When the mounting plate 17 moves linearly up and down, it synchronously drives the laser cutting head 24 to move linearly up and down for adjustment, so as to realize the adjustment of the cutting position of the laser cutting head 24 for the steel plate in the front-back, left-right, and up-down linear movements;

[0030] By controlling the start of the fourth motor 21, when the fourth motor 21 starts, it drives the rotating frame 22 to rotate horizontally. When the rotating frame 22 rotates horizontally, it synchronously drives the laser cutting head 24 to swing horizontally for adjustment. By controlling the start of the fifth motor 23, when the fifth motor 23 starts, it drives the laser cutting head 24 to swing vertically for adjustment, so as to realize the adjustment of the cutting position of the laser cutting head 24 for the steel plate in the front-back, left-right, and up-down linear movements, and at the same time, the cutting angle of the laser cutting head 24 can be swung horizontally and vertically;

[0031] Meanwhile, when the movable support plate 3 moves linearly back and forth and the movable frame 10 moves linearly left and right, the buffer columns 28 will respectively limit the movement limits of the movable support plate 3 and the movable frame 10. When the movable support plate 3 and the movable frame 10 move and touch the buffer columns 28, the buffer columns 28 will push the compression buffer springs 29 while moving linearly inward along the inner wall of the outer end of the limit tube 26. Thus, the buffer springs 29 cooperate with the buffer columns 28 to respectively play the role of buffering the movement limits of the movable support plate 3 and the movable frame 10. At the same time, when the buffer columns 28 move linearly inward along the inner wall of the outer end of the limit tube 26, they will press the pressing limit switch 27. When the pressing limit switch 27 is pressed, the first motor 4 and the second motor 11 can be respectively controlled to stop rotating through the pressing limit switch 27, so as to realize the functions of buffering the movement limits and protecting the movable support plate 3 and the movable frame 10.
