Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a steel structure fixed-distance cutting machine. Background Technology

[0002] In numerous fields such as industrial production, construction, and machining, cutting machines play a crucial role as equipment for cutting and processing various materials. These machines can achieve precise cutting of steel structures through high-speed operation or specific cutting actions, meeting the processing requirements of different projects for the size and shape of steel structures. To ensure the cutter can flexibly return to its original position during the cutting process, existing steel structure cutting machines are generally equipped with a spring structure that pushes the cutter upwards. This spring is usually connected between the machine body and the cutter. In the non-cutting state, the spring force can lift the cutter, avoiding unnecessary contact and wear between the cutter and the worktable or the steel structure to be cut. During cutting operations, the operator needs to manually press the cutter downwards to overcome the upward force of the spring, ensuring the cutter is stably pressed against the surface of the steel structure to be cut. This ensures the stability and accuracy of the cutting process and prevents problems such as cutting deviation and skipping due to poor contact between the cutter and the steel structure surface.

[0003] However, this spring-based structure for cutter reset and auxiliary positioning has significant drawbacks. Since the spring force is positively correlated with its deformation, as the operator presses down on the cutter, the spring's compression deformation increases, and the resulting upward force also strengthens significantly. This means that during cutting, especially when cutting thicker steel structures or when the cutting path requires sustained downward pressure, the operator must continuously apply greater downward pressure to overcome the increasing spring force and maintain stable pressure on the steel surface. Over extended periods, this puts a heavy load on the operator's hands and arms, easily leading to fatigue. Furthermore, for operators with relatively weaker physical strength, this strenuous operation further increases the difficulty of their work. Therefore, the existing spring-based cutter reset structure in cutting machines requires significant improvement; a technical solution that effectively reduces operator effort and improves operational comfort and stability is urgently needed. Utility Model Content

[0004] In view of the above-mentioned prior art, the present invention provides a steel structure fixed-distance cutting machine, which can effectively reduce the operating effort of workers and improve the comfort and stability of operation.

[0005] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows: A steel structure fixed-distance cutting machine includes a base, a swing seat, and a cutter. The base is provided with a first spring and an eccentric wheel, and the swing seat is provided with the cutter. The swing seat is hinged to the base. The first spring is connected to the eccentric wheel through a first traction rope, and the eccentric wheel is connected to the swing seat through a second traction rope. When the swing seat swings downward, it drives the eccentric wheel to rotate and compress the first spring. As the eccentric wheel rotates, the lever arm of the first traction rope decreases, and the lever arm of the second traction rope increases.

[0006] Furthermore, the eccentric wheel is provided with a groove, and the first traction rope and the second traction rope are located in the groove.

[0007] Furthermore, the first spring is a tension spring, and hooks are provided at both ends of the first spring. The base is provided with a fixing ring that cooperates with the hook at the lower end, and the first traction rope is connected to the hook at the upper end.

[0008] Furthermore, the cutter includes a motor and a cutting blade, the motor is mounted on the swing base, and the motor output shaft is connected to the cutting blade.

[0009] Furthermore, the swing seat is equipped with an operating handle.

[0010] Furthermore, a distance measure is installed on the base. The distance measure includes a roller, a rotary encoder, an MCU microcontroller, an operation button, and a display. The roller is connected to the rotary encoder. The rotary encoder, the operation button, and the display are respectively connected to the MCU microcontroller via signals. The roller is rotatably connected to one side of the base.

[0011] Furthermore, the surface of the roller is provided with an anti-slip layer.

[0012] Furthermore, a slider and a second spring are installed on the base. The slider is slidably connected to the base, and a pressure roller is installed on the slider. The second spring pushes the slider to move closer to the roller.

[0013] Furthermore, the second spring is a compression spring, the base is provided with a groove, the slider is slidably connected to the groove, and the second spring is located in the groove.

[0014] Furthermore, the slider is a T-shaped slider, the slide groove is a T-shaped slide groove that cooperates with the slider, the side of the slider and the inner side of the slide groove are provided with locking protrusions, and the pressure spring is inserted into the locking protrusions.

[0015] The beneficial effects of this invention are as follows: During cutting, pulling the swing seat downwards causes it to swing downwards. As the swing seat swings downwards, the second traction rope pulls the eccentric wheel to rotate. The eccentric wheel simultaneously releases the second traction rope and winds the first traction rope. However, because the eccentric wheel rotates, the lever arm of the second traction rope increases while the lever arm of the first traction rope decreases. Therefore, although the deformation of the first spring continuously increases, the resistance encountered by the swing seat during downward swing gradually decreases. Thus, when cutting steel structures, pressing down the swing seat reduces the force required for the cutter to cut the steel structure, allowing for better control of the cutter's cutting action. This also reduces effort during prolonged cutting processes and lowers the labor intensity for workers. After cutting, the swing seat can swing upwards to return to its original position under the influence of the first spring. This invention effectively reduces the operator's effort, improves work comfort and stability. Attached Figure Description

[0019] Example 1 Please refer to the attached document. Figures 1-3 This application provides a steel structure fixed-distance cutting machine, including a base 1, a swing seat 2, and a cutter 3. The base 1 is equipped with a first spring 4 and an eccentric wheel 5. The swing seat 2 is equipped with the cutter 3. The swing seat 2 is hinged to the base 1. The first spring 4 is connected to the eccentric wheel 5 through a first traction rope 6. The eccentric wheel 5 is connected to the swing seat 2 through a second traction rope 7. When the swing seat 2 swings downward, it drives the eccentric wheel 5 to rotate and compress the first spring 4. As the eccentric wheel 5 rotates, the lever arm of the first traction rope 6 decreases, and the lever arm of the second traction rope 7 increases. The base 1 is fixed to the ground, and the swing seat 2 is provided on the base 1, allowing it to swing relative to the base 1. The cutter 3 is provided on the swing seat 2 for cutting the steel structure. The first spring 4 is provided on the base 1, and its elastic force drives the swing seat 2 to swing upward. After cutting, the swing seat 2 can swing upward, allowing the cutter 3 to separate from the cut steel structure for convenient operation. An eccentric wheel 5 is also installed on the base 1. The eccentric wheel 5 is positioned higher than the hinge point between the swing arm and the base 1. The eccentric wheel 5 is connected to the swing arm via a second traction rope 7 and simultaneously connected to the first spring 4 via a first traction rope 6. In the initial state, the swing seat 2 is positioned at the top, facilitating the pushing of the steel structure to the cutting station. During cutting, the swing seat 2 is pulled downwards. As the swing seat 2 swings downwards, the second traction rope 7 pulls the eccentric wheel 5 to rotate. The eccentric wheel 5 simultaneously releases the second traction rope 7 and winds the first traction rope 6. However, because the lever arm of the second traction rope 7 increases while the lever arm of the first traction rope 6 decreases as the eccentric wheel 5 rotates, although the deformation of the first spring 4 continuously increases, the resistance encountered by the swing seat 2 during downward swing gradually decreases. Therefore, when cutting the steel structure, pressing down on the swing seat 2 reduces the force required for the cutter 3 to cut the steel structure. This allows for better control of the cutter 3's cutting of the steel structure, making the process more labor-saving during prolonged cutting and reducing the workload of the workers. After the cutting is completed, it can swing upward and reset under the action of the first spring 4.

[0020] Specifically, the eccentric wheel 5 is provided with a groove 8, and the first traction rope 6 and the second traction rope 7 are located in the groove 8. The first traction rope 6 and the second traction rope 7 are located in different grooves 8, which can ensure that the first traction rope 6 and the second traction rope 7 are wound and released in an orderly manner.

[0021] Specifically, the first spring 4 is a tension spring, and hooks 9 are provided at both ends of the first spring 4. The base 1 is provided with a fixing ring 10 that cooperates with the hooks 9 at the lower end. The first traction rope 6 is connected to the hooks 9 at the upper end. By fixing the first spring 4 in the fixing ring 10 through the hooks 9 at the lower end and connecting it to the first traction rope 6 through the hooks 9 at the upper end, the connection stability of the first spring 4 can be improved.

[0022] Specifically, the cutter 3 includes a motor 11 and a cutting blade 12. The motor 11 is mounted on the swing base 2, and the output shaft of the motor 11 is connected to the cutting blade 12. When the motor 11 is working, it drives the cutting blade 12 to rotate, thereby cutting the steel structure.

[0023] Specifically, the swing seat 2 is equipped with an operating handle 13. The swing seat 2 is rotated by operating the handle 13, making operation more convenient.

[0024] Specifically, a distance measurer 14 is installed on the base 1. The distance measurer 14 includes a roller 15, a rotary encoder 16, an MCU microcontroller 17, an operation button 18, and a display 19. The roller 15 is connected to the rotary encoder 16. The rotary encoder 16, the operation button 18, and the display 19 are respectively connected to the MCU microcontroller 17. The roller 15 is rotatably connected to one side of the base 1. When cutting the steel structure, the steel structure is placed against the roller 15, and then the steel structure is pushed to move. As the steel structure moves, it drives the roller 15 to rotate. The length of the steel structure is measured based on the number of rotations of the roller 15, thereby achieving the purpose of distance measurement. The rotary encoder 16 is set on the roller 15. The rotary encoder 16 is a sensor used to detect the rotation of the roller 15. It transmits the detected number of rotations of the roller 15 to the MCU microcontroller 17 and displays it on the display 19. The operator can obtain the length of the steel structure based on the display 19, thereby completing the distance-based cutting. The MCU microcontroller 17 is also connected to the operation button 18, which can be used to reset the reading to zero for the next test.

[0025] Specifically, the surface of the roller 15 is provided with an anti-slip layer 20. Preferably, the anti-slip layer 20 is made of an anti-slip rubber material. This improves anti-slip performance and increases measurement accuracy.

[0026] Example 2 Please refer to the attached document. Figure 4 The difference between this embodiment and Embodiment 1 is that a slider 21 and a second spring 22 are installed on the base 1. The slider 21 is slidably connected to the base 1, and a pressure roller 23 is installed on the slider 21. The second spring 22 pushes the slider 21 to move closer to the roller 15. Under the action of the second spring 22, the slider 21 moves towards the roller 15, allowing the steel structure to pass between the roller 15 and the pressure roller 23, ensuring that the steel structure stably drives the roller 15 to rotate during movement, and accurately reading the values.

[0027] Specifically, the second spring 22 is a compression spring, the base 1 is provided with a groove 24, the slider 21 is slidably connected to the groove 24, and the second spring 22 is located within the groove 24. Preferably, a baffle can be provided above the groove 24, connected to the slider 21, to prevent metal shavings from entering the groove 24. Alternatively, the groove 24 can be provided with a vertically continuous channel, allowing metal shavings to fall downwards and prevent accumulation. The connection between the slider 21 and the groove 24 improves the stability of the slider 21's sliding motion.

[0028] Specifically, the slider 21 is a T-shaped slider 21, and the slide groove 24 is a T-shaped slide groove 24 that cooperates with the slider 21. The side of the slider 21 and the inner side of the slide groove 24 are provided with locking protrusions 25, and the pressure spring is inserted into the locking protrusions 25. The T-shaped structure prevents the slider 21 from disengaging from the slide groove 24, improving the stability of the slider 21's sliding. Locking protrusions 25 are provided on the inner sides of the slider 21 and the slide groove 24 to hold the second spring 22 within them, improving the stability of the second spring 22.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
