Description

Technical Field

[0001] This utility model relates to the field of steel clamping technology, and in particular to a steel structure cutting device. Background Technology

[0002] Steel structure cutting equipment is widely used in construction, bridge, and shipbuilding industries, and is one of the key pieces of equipment for achieving efficient and precise processing. With the acceleration of industrialization, higher demands are being placed on the cutting accuracy and efficiency of steel structural components. Existing steel structure cutting equipment, by integrating multiple functional modules such as cutting, positioning, and clamping, has significantly improved production efficiency and product quality, reduced labor costs, and driven the rapid development of the industry.

[0003] In practical applications, to ensure cutting quality, the following conventional methods are usually used to fix and clamp the steel structure to be cut: First, manual clamps are used, which require operators to frequently adjust the position, which is time-consuming and labor-intensive; second, pneumatic or electric clamping devices are used, which have a high degree of automation, but are limited in their adaptability to complex-shaped workpieces; third, multi-point clamping is used, which improves stability by applying multiple clamping points to the workpiece surface at the same time, but the structure is more complex and the maintenance cost is high.

[0004] However, the above methods still have certain drawbacks in practical operation, especially when processing long and narrow steel structures. Due to the lack of effective intermediate support and clamping measures, the impact force during cutting can easily cause workpiece deformation or displacement, thus affecting cutting quality and efficiency. Furthermore, traditional clamping mechanisms often only cover a limited working area, failing to meet the needs of workpieces of different sizes and shapes, thus limiting the applicability of the equipment. Therefore, a new technological solution that can effectively address these problems is urgently needed. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] The inventors of this application have discovered that existing steel structure cutting devices are prone to workpiece misalignment and low cutting accuracy during the cutting process. Therefore, this application mainly adopts a steel structure cutting device including a working platform, a cutting mechanism and a clamping mechanism, which achieves the purpose of improving the cutting accuracy and efficiency of steel structure parts. The following is a further detailed description of this application.

[0033] Example 1

[0034] Combination Figures 1-4 As shown in the embodiment of this application, the steel structure cutting device includes a working platform 1, a cutting mechanism, and a clamping mechanism. The working platform 1 has a first limiting baffle 2 and a second limiting baffle 3 formed on both sides. The cutting mechanism includes a fixed seat 4, a cutting blade 5, and a hydraulic push rod 6. The fixed seat 4 is arched and installed at one end of the working platform 1. One end of the hydraulic push rod 6 is connected to the fixed seat 4, and the other end is fixedly connected to the cutting blade 5, with the blade facing the working platform 1. The clamping mechanism includes a drive motor 7, two bearing seats 8, two rotating shafts 9, four synchronous pulleys 10, two synchronous belts 11, a connecting rod 12, a clamping seat 13, and a clamping cylinder 14. This structural design achieves the goal of improving the cutting accuracy and efficiency of steel structural components.

[0035] Specifically, the work platform 1 includes a flat metal plate with two parallel limiting baffles 2 and 3. These baffles limit the position of the steel structural components, preventing the workpiece from shifting during the cutting process. The first limiting baffle 2 and the second limiting baffle 3 can be made of high-strength steel to ensure sufficient rigidity and durability. Furthermore, these two baffles can be fixed to the work platform 1 by welding or bolting to ensure their sturdiness and reliability.

[0036] In the cutting mechanism, the fixed base 4 adopts an arched structure, made of high-strength aluminum alloy, which has good bending resistance and lightweight characteristics. One end of the fixed base 4 is fixed to one end of the work platform 1 by multiple bolts, while the other end supports the entire cutting mechanism. The hydraulic push rod 6 is a model with a large stroke and high pressure, which can provide stable propulsion force over a long distance, thereby driving the cutting blade 5 to perform efficient cutting operations. The cutting blade 5 is made of high-speed steel, which has excellent wear resistance and heat resistance, and can handle various complex cutting tasks. The cutting edge of the cutting blade 5 is precision ground to ensure a straight and smooth cut.

[0037] The design of the clamping mechanism is one of the core innovations of this application. The drive motor 7 is a high-efficiency servo motor, capable of precisely controlling rotational speed and angle, thus achieving smooth and reliable transmission. Two bearing seats 8 are respectively fixed to the inner sides of the first limiting baffle 2 and the second limiting baffle 3, using rolling bearings instead of sliding bearings to reduce friction loss and extend service life. Two rotating shafts 9 are respectively installed in these two bearing seats 8, with one end of one rotating shaft 9 also equipped with a synchronous pulley 10, connected to the output end of the drive motor 7. A first synchronous belt 11 is wound between the synchronous pulley 10 at the output end of the drive motor 7 and one synchronous pulley 10 on the first rotating shaft 9, and a second synchronous belt 11 is wound between the other synchronous pulley 10 on the first rotating shaft 9 and the synchronous pulley 10 on the second rotating shaft 9. This double synchronous belt 11 design makes power transmission more uniform, avoiding the problem of excessive wear caused by uneven force on a single synchronous belt 11. Specifically, multiple clamping seats 13 can be fixed to the connecting rod 12 by bolt connection, and the spacing can be adjusted according to the actual length and shape of the workpiece. Each clamping cylinder 14 is also fixed to the corresponding clamping seat 13 by bolts, with the telescopic end facing the work platform 1. It can firmly clamp the steel structure before cutting, effectively preventing the workpiece from vibrating and displacing during the cutting process.

[0038] The implementation principle of this embodiment is as follows: through the coordinated action of multiple clamping seats 13 and clamping cylinders 14, it can be ensured that the workpiece is effectively clamped at any position. This design is particularly advantageous during the cutting of long workpieces or multi-layered stacked workpieces. It not only improves the cutting quality but also significantly enhances safety and stability.

[0039] Both ends of the connecting rod 12 have threaded holes, which are threaded to the middle of the two rotating shafts 9. This allows the connecting rod 12 to move along a predetermined path under the drive of the drive motor 7. The clamping seat 13 is fixedly mounted on the connecting rod 12, and its position can be adjusted as needed to accommodate steel structural members of different lengths. The clamping cylinder 14 is also fixed on the clamping seat 13, with its telescopic end facing the work platform 1. It can firmly clamp the steel structural member before cutting, preventing it from vibrating or displacing during the cutting process.

[0040] The implementation principle of this embodiment is as follows: First, the steel structure to be cut is placed on the work platform 1 and pressed against the first limiting baffle 2 or the second limiting baffle 3. Then, the drive motor 7 is started, and through the linkage of the synchronous belt 11 and the rotating shaft 9, the connecting rod 12 is moved along the set trajectory, thereby bringing the clamping seat 13 and the clamping cylinder 14 to the appropriate position. Next, the clamping cylinder 14 is activated, extending its telescopic end to clamp the steel structure, ensuring it remains stable. Finally, the hydraulic push rod 6 is activated, pushing the cutting blade 5 downward to begin precise cutting of the steel structure. Throughout the cutting process, the presence of the clamping mechanism effectively prevents workpiece deformation and displacement, greatly improving cutting quality and efficiency.

[0041] Example 2

[0042] As another embodiment of this utility model, the difference between this embodiment and the above embodiments is that the cutting blade 5 has a special design. The end face away from the clamping mechanism is arranged on the same plane as the cutting blade surface of the cutting blade 5, while the end face facing the clamping mechanism is arranged at an angle. The advantages of this design are: on the one hand, the horizontally arranged end face can ensure the neatness of the cross-section; on the other hand, the angled end face can form a compression, which facilitates the breaking of the steel structure.

[0043] Specifically, the main body of the cutting blade 5 is still made of high-speed steel, but a special coating has been added to the blade edge to enhance its wear resistance and corrosion resistance. The blade's tilt angle can be adjusted according to actual needs, with an optimal value generally recommended within the range of 10° to 30°. Furthermore, to further improve cutting performance, a cooling nozzle can be added to the front of the blade to cool it using high-pressure gas or liquid, ensuring it remains in optimal working condition.

[0044] Example 3

[0045] As another embodiment of this utility model, the difference between this embodiment and Embodiment 1 is that this embodiment adds a receiving mechanism, including a receiving plate 15 and a receiving bracket 16. The receiving bracket 16 is located at the end of the working platform 1 away from the pressing mechanism, and the receiving plate 15 is mounted on the receiving bracket 16, with a height lower than the table height of the working platform 1. The main purpose of this system is to automatically receive the falling waste material after cutting, reducing the burden on operators and improving work efficiency.

[0046] Specifically, the receiving bracket 16 is made of high-strength steel and is fixed to the end of the work platform 1 by welding or bolting. The receiving plate 15 can be made of stainless steel, which has good corrosion resistance and a smooth surface for easy cleaning. The height of the receiving plate 15 is slightly lower than the table surface of the work platform 1, so that after cutting, the cut material can fall directly onto the receiving plate 15 without manual intervention. The width and length of the receiving plate 15 should be appropriately adjusted according to the actual size of the workpiece to ensure that it has sufficient load-bearing capacity.

[0047] The implementation principle of this embodiment is as follows: after cutting, the cut material will fall naturally and be caught by the receiving plate 15 below. Operators only need to clean the receiving plate 15 periodically, eliminating the need to manually collect waste material each time, greatly saving time and labor costs. In addition, the low height design of the receiving plate 15 also helps to reduce the impact force when waste material falls, avoiding damage to the ground or other equipment.

[0048] Furthermore, the receiving mechanism in this embodiment also includes two pneumatic push rods 17. The end of the receiving plate 15 facing away from the working platform 1 is rotatably connected to the receiving bracket 16. The two pneumatic push rods 17 are respectively installed on both sides of the receiving plate 15. The lower end of the pneumatic push rod 17 is rotatably connected to the receiving bracket 16, and the upper end is rotatably connected to the receiving plate 15. Specifically, the pneumatic push rod 17 uses a high-performance gas spring, which can provide a large thrust in a small space, ensuring the stability and reliability of the receiving plate 15. The upper and lower ends of the pneumatic push rod 17 are respectively connected to the receiving plate 15 and the receiving bracket 16 through pins, allowing them to rotate freely within a certain range. A rubber pad can also be added to the back of the receiving plate 15 to increase its friction coefficient and prevent waste from slipping on its surface. This design allows the receiving plate 15 to swing freely within a certain range, making it convenient to adjust its tilt angle and facilitating unloading by workers.

[0049] The implementation principle of this embodiment is as follows: by adjusting the pneumatic push rod 17, the receiving plate 15 can operate at different tilt angles, which is beneficial for workers to unload materials and will not cause material accumulation due to excessive tilting. This flexible design allows the receiving mechanism to adapt to more application scenarios, improving the versatility and practicality of the entire system.

[0050] Furthermore, the steel structure cutting device in this embodiment adds a material collection rack 18, which is frame-shaped and located at the end of the receiving mechanism away from the working platform 1. This new component is mainly used to centrally store the incoming materials cut from the receiving plate 15, further simplifying the management process of the cut materials and improving the cleanliness of the production site.

[0051] Specifically, the material collection rack 18 adopts a rectangular frame structure, which is spliced ​​from multiple steel plates, giving it high strength and stability. The bottom of the material collection rack 18 is equipped with rollers for easy movement within the workshop. To prevent waste material from spilling during transportation, the material collection rack 18 is also surrounded by a fence of moderate height, which can accommodate a large amount of waste material without hindering the operation of the personnel.

[0052] The implementation principle of this embodiment is as follows: when the cut steel structure material on the receiving plate 15 accumulates to a certain level, it can be easily poured into the collection rack 18. The large-capacity design of the collection rack 18 allows for the storage of a large amount of cut steel structure material at one time, reducing the number of cleaning operations and improving work efficiency. In addition, the collection rack 18 with wheels is also very portable, allowing operators to move it to a designated location for unified processing at any time, keeping the production site clean and tidy.

[0053] Furthermore, this embodiment of the steel structure cutting device includes a toolbox 19, which is installed on one side of the work platform 1. The toolbox 19 is mainly used to store various tools and auxiliary equipment required for cutting, making it convenient for operators to access and improving work efficiency.

[0054] Specifically, toolbox 19 is made of metal and has multiple internal compartments for storing different tools and accessories. The exterior of toolbox 19 features handles and latches for easy opening and closing. The toolbox 19's doors can also be labeled with common tool names to help operators quickly find the required tools. By placing toolbox 19 next to the work platform 1, various cutting tools can be centrally managed and stored, reducing operator time spent searching for tools and improving work efficiency. Furthermore, the toolbox 19's logical layout and clear labeling help maintain the tools in good condition and extend their lifespan.
