Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a laser cutting device for processing metal support frames inside tobacco curing barns. Background Technology

[0002] Laser cutting is a high-precision, high-efficiency metal processing technology that uses a focused laser beam to melt and vaporize metal materials, and is widely used in the processing of various metal components. As a key facility for tobacco curing, the internal metal support frame of the tobacco curing barn needs to be stable and adaptable. It is typically made of metal materials such as structural steel, and precise cutting is required to ensure that the dimensions of each component match, thus meeting the structural requirements for building the tobacco curing barn.

[0003] Existing laser cutting equipment struggles to simultaneously ensure stable clamping of components and continuous cutting of the upper and lower surfaces when processing metal support frames for tobacco curing barns. This often necessitates manual rotation or movement of the support frame to complete double-sided processing. This not only easily leads to component positioning misalignment, affecting cutting accuracy, but also requires recalibration, reducing processing efficiency. Furthermore, the smoke and dust generated during cutting easily disperse, interfering with the cutting line of sight and affecting processing accuracy. There is also a lack of an efficient smoke extraction mechanism synchronized with the cutting action. In addition, the existing equipment's cutting head angle switching and position adjustment mechanisms are complex, making it difficult to quickly and stably switch between the cutting states of the upper and lower surfaces.

[0004] Based on this, a laser cutting device for processing metal support frames inside tobacco curing barns is proposed. Summary of the Invention

[0029] Specifically, as shown in Figure 6 Fixed frame 3 is connected with slide rail 32, and both ends of clamping strip 26 are slidably connected on slide rail 32, so that clamping strip 26 can be well limited by setting slide rail 32, and the stability of clamping strip 26 sliding on fixed frame 3 is ensured.

[0030] Specifically, as shown in Figure 6 The positioning member includes clamp 31, and clamp block 25 is connected on fixed frame 3, clamp 31 is rotatably connected on clamping strip 26 through hinged frame 30, a plurality of clamp blocks 25 are provided, and the plurality of clamp blocks 25 are equidistantly connected on the outside of fixed frame 3, when clamp 31 is turned over, clamp 31 can be clamped between clamp blocks 25, so that the connection position of clamping strip 26 is stabilized, and the clamping and fixing of metal support frame of various sizes can be completed by adjusting screw rod 27, the cutting processing mode of fixing metal support frame without turning over or moving can avoid the position deviation of metal support frame caused by turning over or moving, which affects the subsequent cutting precision, and the traditional moving or turning over processing mode needs to be repositioned after displacement, so that the cutting processing efficiency is affected.

[0031] Specifically, as shown in Figure 6As shown, the screw rod 27 is fixedly connected with a knob 28 and an abutting end 29 at both ends, respectively. By arranging the abutting end 29, the contact area between the metal support frame and the clamp during clamping is increased, thereby improving the clamping stability. By arranging the knob 28, the screw rod 27 is conveniently rotated.

[0032] Specifically, as shown in Figure 5 As shown, the connecting frame 1 is slidingly connected with a smoke exhaust member 8. The smoke exhaust member 8 is connected with a connecting pipe 9, which is used to be connected with an external smoke exhaust pipeline. The smoke dust generated during cutting is pumped into the pipeline by a gas pump arranged at one end, so as to avoid the influence of the smoke dust on the machining precision. The smoke exhaust member 8 is connected with a spring 7 at one side. The smoke exhaust member 8 is connected with a button 24 at one side. The button 24 has an effect of controlling the operation of the smoke exhaust member 8. The spring 7 can ensure that the smoke exhaust member 8 and the connecting strip 19 abut against each other, so as to press the button 24 by the connecting strip 19, thereby controlling the timely operation of the smoke exhaust member 8.

[0034] Specifically, as shown in Figure 3 and Figure 4 As shown, the driving mechanism includes a motor 12. The connecting frame 1 is slidingly connected with a translation frame 10 at one side. The translation frame 10 is provided with a vertical slot 11. The connecting strip 19 is slidingly connected with the vertical slot 11 at both ends through a sliding column 14. The connecting frame 1 is provided with a U-shaped slot 4. The sliding column 14 is slidingly connected with the U-shaped slot 4. The motor 12 is slidingly connected with the translation frame 10. The motor 12 is connected with a connecting sheet 13 outside. The connecting sheet 13 is sleeved on the sliding column 14. The motor 12 is connected with a roller 23 at an output end. The roller 23 is in rolling contact with one side of the U-shaped slot 4. When the motor 12 is started, the roller 23 can be rotated, thereby driving the motor 12 to move along the U-shaped slot 4. The sliding column 14 is connected with a gear 21. The translation frame 10 is connected with a rack 22 which cooperates with the gear 21. By arranging the rack 22 and the gear 21, the position of the cutting head 20 at the highest point and the lowest point can be deflected and limited, thereby ensuring that the cutting head 20 can be in the vertical downward and vertical upward cutting machining states, respectively.

[0035] Specifically, as shown in Figure 3 and Figure 4As shown, a clamping frame 16 is connected to the translation frame 10. The clamping frame 16 can stabilize the connection between the translation frame 10 and the connecting frame 1. A sliding groove 17 is provided on the translation frame 10. A sliding hoop 15 is fixedly connected to the outside of the motor 12. The sliding hoop 15 is slidably connected to the sliding groove 17. The sliding hoop 15 can ensure the stability of the connection between the motor 12 and the translation frame 10, and ensure that the motor 12 itself cannot rotate.

[0036] In summary, the laser cutting device for processing metal support frames in tobacco curing barns provided in this embodiment can perform high-precision and efficient cutting and shaping of the metal components required for the metal support frames of tobacco curing barns, providing key processing guarantees for the standardized production of metal support frames in tobacco curing barns. During the cutting process, the metal support frame needs to be placed on the fixed frame 3, the clamping bar 26 is moved to a position that matches the size of the metal support frame, and then the clamp 31 is flipped and engaged with the clamping block 25, thereby ensuring that the position of the clamping bar 26 is fixed. Then, the knob 28 is rotated, and the abutment end 29 of one end of the screw 27 abuts against the metal support frame, thereby completing the fixation of the metal support frame structure.

[0037] The motor 12 is started by the control unit on the outside of the cutting device. The motor 12 drives the roller 23 to rotate. Since the roller 23 rolls and contacts one side of the U-shaped groove 4, it can drive the motor 12 to move along the U-shaped groove 4. When the motor 12 is horizontally above the metal support frame, it slides on the connecting strip 19 with the cutting sleeve 18. Thus, the cutting head 20 can accurately cut the metal support frame below. At this time, the cutting head 20 can move in a plane on the horizontal plane above the metal support frame.

[0038] During the movement, one side of the connecting strip 19 abuts against the button 24 on the smoke exhaust component 8, thereby pressing the button 24. At this time, the smoke exhaust component 8 can be started synchronously during cutting. Moreover, the smoke exhaust component 8 can always be positioned on one side of the cutting head 20 through the action of the spring 7, accurately assisting the cutting head 20 in cutting operations and timely removing the smoke and dust generated during cutting.

[0039] After the upper part of the metal support is processed, the motor 12 can move the roller 23 to the vertical part of the U-shaped groove 4. The sliding column 14 enters the vertical part at the same time. Therefore, the vertical part and the horizontal part of the U-shaped groove 4 have different widths. The vertical part can accommodate the roller 23 and the sliding column 14 side by side. At this time, the height of the motor 12 decreases, and the translation frame 10 stops moving horizontally. Under the action of the connecting piece 13, the height of the sliding column 14 can be lowered. Due to the interaction between the gear 21 and the rack 22 on the sliding column 14, the gear 21 rotates and drives the cutting head 20 to rotate synchronously. When the motor 12 is moved to the lowest point, the cutting head 20 is rotated to the vertical upward position. At this time, the motor 12 continues to run, which can drive the cutting head 20 to perform cutting operations on the lower part of the metal support frame.

[0040] When cutting under the metal support frame of the cutting head 20, the smoke exhaust component 8 located below can be moved to discharge smoke and dust during the cutting process, thereby improving the cutting accuracy.

[0041] This cutting device allows cutting operations to be completed without moving or flipping the metal support frame, effectively avoiding the impact of metal support frame movement on processing accuracy. Furthermore, the cutting operations on both the upper and lower surfaces of the metal support frame can be carried out continuously, greatly improving processing efficiency.

[0042] The above description of the embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
