Description

Technical Field

[0001] This utility model belongs to the field of profile processing technology, and in particular relates to a high-toughness angle steel cutting device. Background Technology

[0002] As a core infrastructure of power grid construction, power transmission towers undertake the critical task of long-distance transmission of high-voltage electricity, and their structural stability directly determines the safety and reliability of power grid operation. Angle steel, as a core load-bearing component of power transmission towers, must possess high strength, high wind load resistance, and weather resistance. Therefore, high-toughness special steels are often used. In the processing and manufacturing of power transmission towers, angle steel needs to be cut to specific lengths according to the design requirements of the tower nodes.

[0003] In current processing scenarios, angle steel is often cut into sections using handheld or stationary abrasive wheel cutting machines (grinding machines). These types of equipment cut angle steel by using a high-speed rotating abrasive wheel blade. The clamping is unstable, and the angle steel is prone to displacement during the cutting process, resulting in tilted cuts and dimensional deviations. Utility Model Content

[0004] In view of the technical problems existing in the background art, this utility model provides a high-toughness angle steel cutting device.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: A high-toughness angle steel cutting device includes a base plate, a frame mounted on the outer top of the base plate, an angle steel placement seat mounted in the middle of the top of the base plate, an angle steel cutting head mounted on one side of the top of the angle steel placement seat, an electric hydraulic rod mounted on the top of the frame, the output end of the electric hydraulic rod being fixedly connected to the top of the angle steel cutting head, a limiting block mounted on the top of the other side of the angle steel placement seat, the angle steel placement seat being located between the angle steel cutting head and the limiting block, and a threaded hole on the other side of the top of the frame, the threaded hole having an internal threaded connection to a height adjustment mechanism for adjusting the height of the limiting block.

[0006] Optionally, the height adjustment mechanism includes a threaded rod, the outer wall of which engages with the inner wall of a threaded hole, a retaining seat rotatably connected to the bottom end of the threaded rod, the bottom end of the retaining seat being fixedly connected to the top end of a limiting pressure block, and an adjustment knob installed at the top end of the threaded rod.

[0007] Optionally, both sides of the angle steel cutting head are slidably connected to a first slide rod, and one side of the pair of first slide rods is fixedly connected to both sides of the inner wall of the frame. Both sides of the limiting pressure block are slidably connected to a second slide rod, and one side of the pair of second slide rods is fixedly connected to both sides of the inner wall of the frame.

[0008] Optionally, the top center of the angle steel placement seat is provided with a V-shaped groove for placing the angle steel, and the bottom center of the angle steel cutting head and the bottom center of the limiting pressure block are both V-shaped structures.

[0009] Optionally, support bases are installed at the four corners of the bottom of the base plate, and the bottom of the support bases is provided with anti-slip texture.

[0010] Optionally, the frame is equipped with a protective mechanism on one end face near the angle steel cutting head.

[0012] Optionally, a control panel for controlling the extension and retraction of the electro-hydraulic rod is installed on one side of the frame.

[0013] This utility model has the following advantages and beneficial effects: This invention achieves stable positioning and precise holding of the angle steel during cutting by setting up a multi-point clamping mechanism and a synchronous limiting guide structure, and using an adjustable clamping component to lock the angle steel axially and laterally in a coordinated manner. When the clamping block moves on the guide rail, it is constrained and supported by the double-sided limiting plates, which can effectively suppress the lateral swing of the angle steel during the clamping, feeding, and cutting stages. When the clamping component acts on the surface of the angle steel, the clamping force is transmitted in a direction perpendicular to the cutting surface, which will not cause the angle steel to be pushed away as in traditional side clamping methods. Structurally, it avoids the problem of deviation or tilting during cutting, so that the angle steel can be reliably held in one positioning, improves the consistency of cutting dimensions, and reduces repeated calibration and scrap rate.

[0014] Compared to traditional abrasive wheel cutting or single-point clamping cutting equipment, this invention improves the clamping stability, cutting accuracy, and operational safety of angle steel. The device effectively reduces the probability of displacement during the cutting of high-toughness angle steel, minimizes rework, improves processing efficiency, and effectively achieves precise positioning, stable cutting, and safety protection, meeting the needs for efficient and high-precision cutting of high-toughness angle steel.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0018] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Example like Figures 1-5 As shown, a high-toughness angle steel cutting device includes a base plate 1, which provides a rigid support foundation for the device. A frame 3 is installed on the outer top of the base plate 1, and an angle steel placement seat 4 is installed in the middle of the top of the base plate 1. The angle steel placement seat 4 provides an angle steel positioning platform to achieve precise placement of the angle steel. An angle steel cutting head 6 is provided on one side of the top of the angle steel placement seat 4. An electric hydraulic rod 5 is installed on one side of the top of the frame 3. The output end of the electric hydraulic rod 5 is fixedly connected to the top of the angle steel cutting head 6. A limiting block 8 is provided on the other side of the top of the angle steel placement seat 4. The angle steel placement seat 4 is located between the angle steel cutting head 6 and the limiting block 8. The angle steel cutting head 6 is driven to cut vertically by the electric hydraulic rod 5, which is suitable for cutting high-toughness angle steel. The limiting block 8 presses the angle steel to prevent it from shifting during cutting. A threaded hole 301 is opened on the other side of the top of the frame 3. A height adjustment mechanism 9 for adjusting the height of the limiting block 8 is installed inside the threaded hole 301.

[0020] Furthermore, the height adjustment mechanism 9 includes a threaded rod 901, the outer side of which engages with the inner side of the threaded hole 301. A retaining seat 902 is rotatably connected to the bottom end of the threaded rod 901. The bottom end of the retaining seat 902 is fixedly connected to the top end of the limiting pressure block 8. An adjustment knob 903 is installed on the top end of the threaded rod 901. By engaging the threaded rod 901 with the threaded hole 301, the rotational motion of the height adjustment mechanism 9 is converted into the vertical lifting and lowering of the limiting pressure block 8, adapting to the clamping requirements of angle steels of different thicknesses. The retaining seat 902 enables the rotational connection between the threaded rod 901 and the limiting pressure block 8, preventing the rotation of the threaded rod 901 from causing the limiting pressure block 8 to shift.

[0021] Furthermore, both sides of the angle steel cutting head 6 are slidably connected to first slide rods 7, and one side of each pair of first slide rods 7 is fixedly connected to both sides of the inner wall of the frame 3. Both sides of the limiting pressure block 8 are slidably connected to second slide rods 10, and one side of each pair of second slide rods 10 is fixedly connected to both sides of the inner wall of the frame 3. By fixing the first slide rods 7 on both sides of the angle steel cutting head 6 to the frame 3, the cutting head is guided to move vertically, avoiding uneven cutting surfaces caused by tilting of the cutting head. By using the second slide rods 10 on both sides of the limiting pressure block 8, the limiting pressure block 8 is ensured to rise and fall vertically, avoiding uneven force on the angle steel caused by tilting of the pressure block.

[0022] Furthermore, a V-shaped groove for placing angle steel is provided at the top center of the angle steel placement seat 4. The bottom center of the angle steel cutting head 6 and the bottom center of the limiting pressure block 8 are both V-shaped structures adapted to the angle steel. By adapting the V-shaped groove at the top of the angle steel placement seat 4 to the angle steel, the angle steel can be automatically centered and positioned, avoiding manual positioning deviation. By adapting the V-shaped structure at the bottom of the angle steel cutting head 6 to the angle steel placement seat 4, the angle steel cutting head 6 can be adapted to the angle steel placement seat 4, making it convenient for the angle steel cutting head 6 to press down and cut the angle steel. By adapting the V-shaped structure at the bottom of the limiting pressure block 8, the angle steel can be limited during cutting, preventing the angle steel from bouncing.

[0023] Furthermore, support seats 2 are installed at the four corners of the bottom of the base plate 1. The bottom of the support seats 2 is provided with anti-slip texture. The installation of support seats 2 at the four corners of the bottom of the base plate 1 improves the placement stability of the device.

[0024] Furthermore, the frame 3 is equipped with a protective mechanism 11 on one end face near the angle steel cutting head 6. The protective mechanism 11 blocks cutting debris from bouncing off the angle steel, ensuring the safety of the operator.

[0025] Furthermore, the protective mechanism 11 includes a protective cover 1101, with a hinge 1102 installed at the top of the protective cover 1101. One end of the hinge 1102 is fixedly connected to one side of the top of the frame 3. The protective cover 1101 of the protective mechanism 11 covers the cutting area of ​​the angle steel cutting head 6, blocking the flying debris during shearing, and preventing the high-toughness angle steel from bouncing and injuring people during shearing.

[0026] Furthermore, a control panel 12 for controlling the extension and retraction of the electro-hydraulic rod 5 is installed on one side of the frame 3. Through the control panel 12 on one side of the frame 3, the extension and retraction speed and extension stroke of the electro-hydraulic rod 5 can be precisely controlled.

[0027] Specifically, the working principle of this high-toughness angle steel cutting device is as follows: During use, the operator places the high-toughness angle steel to be cut into the V-shaped groove at the center of the top of the angle steel placement seat 4. The V-shaped groove matches the shape of the angle steel, enabling automatic centering and positioning, effectively avoiding deviations that may occur during manual positioning, and ensuring precise cutting. Depending on the thickness of the angle steel to be cut, the operator rotates the adjusting knob 903 in the height adjustment mechanism 9. Because the outer side of the threaded rod 901 engages with the inner side of the threaded hole 301 on the other side of the top of the frame 3, the rotation of the adjusting knob 903 will cause the threaded rod 901 to move vertically along the threaded hole 301. Simultaneously... The bottom end of the threaded rod 901 is rotatably connected to the top end of the limiting pressure block 8 via a retaining seat 902. The retaining seat 902 prevents the limiting pressure block 8 from shifting when the threaded rod 901 rotates. Ultimately, the limiting pressure block 8 moves vertically up and down along the second slide rod 10 until the V-shaped structure at the bottom center of the limiting pressure block 8 tightly adheres to the surface of the angle steel, firmly pressing the angle steel to prevent displacement or bouncing during cutting. Before cutting, the operator flips the protective cover 1101 in the protective mechanism 11 using the hinge 1102 to cover the cutting area of ​​the angle steel cutting head 6, thereby blocking the flying debris generated during cutting and preventing the high-toughness angle steel from being cut due to its toughness. To prevent injury to operators from bouncing, and to ensure operational safety, the operator uses a control panel 12 mounted on one side of the frame 3 to precisely set the extension speed and stroke of the electric hydraulic rod 5 according to the toughness of the angle steel and the cutting requirements. After the parameters are set, a cutting command is issued through the control panel 12. Upon receiving the command, the electric hydraulic rod 5 begins to work, and its output end pushes the angle steel cutting head 6 to move vertically downward along the first slide rod 7. The first slide rod 7 guides the angle steel cutting head 6 to maintain vertical movement, preventing the cutting head from tilting and causing an uneven cutting surface. Driven by the electric hydraulic rod 5, the V-shaped part of the bottom of the angle steel cutting head 6 is adapted to the angle steel. The structure contacts the angle steel and applies pressure, utilizing its own cutting performance to vertically shear the high-toughness angle steel. After cutting, the operator controls the electric hydraulic rod 5 to retract via the control panel 12, driving the angle steel cutting head 6 to vertically return to its original position along the first slide rod 7. Then, the adjusting knob 903 is rotated in the opposite direction to move the limiting pressure block 8 upward along the second slide rod 10, releasing the pressure on the cut angle steel. Finally, the protective cover 1101 is opened to remove the cut angle steel, completing one cutting operation. This utility model can effectively achieve precise positioning, stable cutting, and safety protection, meeting the needs of high-efficiency and high-precision cutting of high-toughness angle steel, and has high practical value.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
