Description

Technical Field

[0001] This invention relates to the field of steel plate processing technology for iron towers, and in particular to a cutting auxiliary device for processing steel plates for iron towers. Background Technology

[0002] Steel plate cutting is a core process in the manufacture of power transmission towers. It is mainly used to process key structural components such as tower connection plates. By cutting, the components are shaped to meet installation requirements, ensuring precise connection of various tower parts and structural load-bearing stability, which is directly related to the safe and reliable transmission of power. Because tower connection plates are exposed to complex outdoor conditions and subjected to alternating loads for extended periods, sharp corners on their rectangles can easily lead to stress concentration, causing corner cracking and fatigue damage. Therefore, industry standards require connection plates to be cut into chamfered rectangles, i.e., cutting off the small triangles at the four corners. This avoids stress concentration, removes processing burrs, and ensures the mechanical properties and service life of the components.

[0003] Currently, existing technologies for cutting chamfered rectangular steel plates have many shortcomings: most adopt a step-by-step processing mode, first cutting the rectangular outline, then manually transferring the steel plate, aligning it, and then cutting the four corners. The process is cumbersome and requires a lot of manual intervention, which can easily lead to positioning errors, resulting in asymmetrical corner cutting and dimensional deviations. This affects standardized assembly, and manual material transfer poses safety hazards, making it difficult to meet the needs of batch and high-efficiency processing.

[0004] Chinese Patent Publication No. CN217343948U discloses a cutting device for processing steel plates for iron towers. It includes two fixed seats, each with a fixed plate mounted on one side close to the other. Two sets of connecting rods and fixed rods are arranged between the two fixed plates, each set being fixedly connected to both ends of the two fixed plates. The connecting rods are positioned below the fixed rods. Multiple equidistant support plates are arranged between the two fixed plates, with both ends of each support plate fixedly connected to adjacent connecting rods and fixed rods. This patent allows adjustment of the position of the baffles by adjusting the horizontal position of the movable block, ensuring the baffles are in close contact with the sides of the steel plate. By securing the movable block with bolts, the two baffles clamp the sides of the steel plate, improving its stability and subsequent cutting accuracy. The overall structure is simple, easy to operate, and has broad market prospects, making it suitable for widespread adoption.

[0005] However, the above-mentioned device cannot simultaneously chamfer and cut the four corners of the steel plate, and manual transfer is required during the cutting process. Summary of the Invention

The outer surfaces of the two L-shaped connecting rods are slidably connected to the limiting rings at corresponding positions. When the rotating seat rotates, it can drive the two L-shaped connecting rods to rotate synchronously, thereby causing the four plasma cutters at different positions to move linearly on the rectangular track at the same time.

[0013] Preferably, the rotating assembly includes a housing fixedly connected to the lower end of the processing table, a rotating shaft rotatably connected to the right end of the housing, a guide groove is formed on the outer surface of the rotating shaft, a guide bead is fixedly connected to the inner surface of the groove, and the outer surface of the guide bead is slidably connected to the guide groove.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This invention first uses the processing table and lifting components to position and stably press the steel plate, avoiding the tedious manual handling, alignment, and repeated clamping operations, thus reducing manpower input. Then, by using the lifting, moving, and rotating components, four plasma cutting machines can be driven simultaneously to complete the one-time synchronous cutting of the four sides of the steel plate, eliminating the cumulative error of multiple positioning in traditional processes. At the same time, the steel plate can be rotated 45 degrees during the lifting stroke, so that the four corners can be chamfered and cut synchronously without manual material transfer. Finally, the cutting component is used to unload the finished steel plate. The entire process can be completed without manual intervention, significantly shortening the steel plate processing cycle of the iron tower, improving production efficiency and finished product qualification rate, while eliminating the safety hazards of personnel contacting the high-temperature cutting area.

[0020] 2. During the lifting and rotation of the lifting assembly, this invention can limit the steel plate using a pressing plate, and the rotation of the L-shaped connecting rod can drive four plasma cutting machines to move synchronously along the rectangular track. This allows for simultaneous cutting of the four sides of the steel plate without manual operation, avoiding errors caused by manual operation and significantly improving cutting efficiency. Simultaneously, the lifting stroke of the lifting assembly can be linked with the guide groove and guide ball to drive the rotating seat to rotate, thus achieving a 45-degree rotation of the steel plate without additional drive, smoothly completing the chamfering and moving cut of the four corners. This seamlessly connects multiple cutting processes. Finally, the continued rise of the lifting plate can trigger the push plate to push the finished steel plate for unloading. The entire process requires no manual intervention for material transfer or removal, integrating dispersed processes, eliminating the risks of high-temperature operations, further optimizing the processing flow, ensuring the consistency of specifications for workpieces in the same batch, and adapting to the batch processing needs of steel tower plates.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] Example 1, as Figure 1 As shown, a cutting auxiliary device for processing steel plates for iron towers includes a processing table 1. A limiting plate 11 is fixedly connected to the upper end of the processing table 1. Three slots 12 are opened on the outer surface of the limiting plate 11. A cutting assembly 2 is provided at the upper end of the processing table 1. The cutting assembly 2 includes four plasma cutters 24. A lifting assembly 3 is provided at the upper end of the processing table 1 to limit the steel plate. A moving assembly 4 is provided at the lower end of the lifting assembly 3 to drive the four plasma cutters 24 to move synchronously. A rotating assembly 5 is provided at the right end of the lifting assembly 3. A feeding assembly 6 is provided at the rear end of the lifting assembly 3 to facilitate pushing the steel plate out of the container.

[0034] The aforementioned limiting plate 11 can position the steel plate before it is cut. The four sides of the steel plate match the three sides of the limiting plate 11, thus determining the position of the steel plate.

[0035] The presence of the slot 12 facilitates the rotation of the steel plate after the four sides have been cut, and prevents its corners from colliding with the limiting plate 11.

[0036] In the operation of this embodiment, the steel plate is first positioned and stably pressed by the cooperation of the processing table 1 and the lifting component 3, avoiding the tedious operation of manual handling and repeated clamping, and reducing manpower input. Then, by using the cooperation of the lifting component 3, the moving component 4 and the rotating component 5, four plasma cutting machines 24 can be driven to complete the one-time synchronous cutting of the four sides of the steel plate, eliminating the cumulative error of multiple positioning in the traditional process. At the same time, the steel plate can be rotated forty-five degrees during the lifting stroke, so that the four corners can be chamfered synchronously without manual material transfer. Finally, the cutting component 6 is used to unload the cut steel plate. The whole process can be completed without manual intervention, which significantly shortens the processing cycle of the steel plate for the iron tower, improves production efficiency and finished product qualification rate, and eliminates the safety hazards of personnel contacting the high-temperature cutting area.

[0037] Example 2, as Figure 1-10 The cutting assembly 2 includes two support frames 21 fixedly connected to the upper end of the processing table 1. A rectangular track 22 is provided at one end of the two support frames 21 that is close to each other. Four movable seats 23 distributed in a rectangular pattern are slidably connected to the outer surface of the rectangular track 22. Four plasma cutters 24 are respectively installed on the surface of the movable seats 23 at corresponding positions.

[0038] The plasma cutting machine 24 mentioned above is a mature existing technology in the field of metal sheet cutting. Its core relies on a high-temperature plasma arc to locally melt the metal at the workpiece cut, and then uses a high-speed plasma gas flow to blow away the molten metal to form a regular cut. It can be used for metal materials commonly used in the processing of iron towers, such as carbon steel and high-strength steel. It has the characteristics of small heat-affected zone, good cut quality and high cutting efficiency. It does not require a lot of subsequent grinding process and is the mainstream cutting equipment in the field of steel structure processing.

[0039] Furthermore, the device can move smoothly on the rectangular track 22 via the moving component 4. During the movement, it can stably maintain the working posture and uniform speed of the plasma cutter 24, enabling continuous cutting along a straight trajectory, effectively avoiding error fluctuations caused by manual cutting, and ensuring the consistency of the cutting dimensions of workpieces in the same batch.

[0040] The lifting assembly 3 includes two hydraulic devices 31 fixedly installed on the upper end of the processing table 1. The output ends of the two hydraulic devices 31 are fixedly connected to a lifting plate 32. A circular groove 33 is provided on the right end of the lifting plate 32. A motor 34 is fixedly installed on the upper end of the hydraulic device 31. A rotating seat 35 is fixedly connected to the output end of the motor 34. A limit block 351 is fixedly connected to the outer surface of the rotating seat 35.

[0041] A connecting rod 36 is fixedly connected to the lower end of the rotating seat 35, and a rotating seat 37 is fixedly connected to the lower end of the connecting rod 36. A pressing plate 38 is rotatably connected to the outer surface of the rotating seat 37.

[0042] Furthermore, the limiting block 351 mentioned above can limit the two L-shaped connecting rods 42. When the lifting plate 32 is rising or falling, the two L-shaped connecting rods 42 remain stationary and are in a sliding connection with the rotating seat 35. This allows the two L-shaped connecting rods 42 to rotate with the rotating seat 35 without affecting the up-and-down movement of the rotating seat 35 itself.

[0043] After placing the steel plate in the designated position, make its three edges fit into the three limiting plates 11 respectively. Then, control the hydraulic device 31 to lower the structure as a whole, including the lifting plate 32, motor 34, rotating seat 35, etc., so that the pressing plate 38 presses on the steel plate to suppress the movement and vibration of the steel plate during the cutting process. Then, start four plasma cutting machines 24 at the same time to cut the four edges of the steel plate.

[0044] The moving component 4 includes four limiting rings 41. The lower ends of the four limiting rings 41 are fixedly connected to the upper ends of the moving base 23 on the same side. The outer surface of the rotating base 35 is slidably connected to two symmetrically arranged L-shaped connecting rods 42. The outer surfaces of the two L-shaped connecting rods 42 are slidably connected to the limiting rings 41 at corresponding positions. When the rotating base 35 rotates, it can drive the two L-shaped connecting rods 42 to rotate synchronously, thereby causing the four plasma cutters 24 at different positions to move linearly on the rectangular track 22 at the same time.

[0045] During the cutting process, the starter motor 34 drives the rotating seat 35 to rotate, which in turn drives the two L-shaped connecting rods 42 to rotate counterclockwise simultaneously. As the two L-shaped connecting rods 42 swing in the same direction, they will move the corresponding limit ring 41, the moving seat 23 and the plasma cutting machine 24 synchronously. During this process, the limit ring 41 and the L-shaped connecting rods 42 are in a sliding state. Therefore, the four plasma cutting machines 24 will be synchronously driven to move in a straight line in different directions on the rectangular track 22, cutting the four sides of the steel plate simultaneously. The four sides of the rectangular body can be cut simultaneously in one stroke, which greatly improves the processing efficiency. At the same time, it completely eliminates the cumulative error of multiple positioning and the positioning error of manual material transfer. It ensures that the specifications and angles of the four cut corners are completely symmetrical and consistent, realizing the standard cut corner rectangular outline of the tower connection plate, improving the structural stability and service life of the connection plate, and greatly reducing the processing cycle of a single steel plate. There is no need for manual intervention in the steel plate transfer operation, which reduces the labor intensity of the operators and eliminates the safety hazards of manual contact with the high-temperature cutting area.

[0046] Furthermore, the four plasma cutters 24 are respectively set on the four sides of the rectangular track 22. Each plasma cutter 24 can only move back and forth in a straight line along its single side. The angle at which the motor 34 drives the rotating seat 35 and the L-shaped connecting rod 42 to rotate each time allows each plasma cutter 24 to move smoothly from one end of the side track to the other end synchronously.

[0047] When the pressing plate 38 presses the steel plate itself, the rotating seat 35 drives the connecting rod 36 to rotate, which will only cause the rotating seat 37 to rotate freely and will not drive the pressing plate 38 to rotate.

[0048] The rotating assembly 5 includes an outer shell 53 fixedly connected to the lower end of the processing table 1. A rotating shaft 51 is rotatably connected to the right end of the outer shell 53. A guide groove 52 is provided on the outer surface of the rotating shaft 51. A guide bead 57 is fixedly connected to the inner surface of the circular groove 33. The outer surface of the guide bead 57 is slidably connected to the guide groove 52.

[0049] The guide groove 52 mentioned above consists of two straight lines and one arc.

[0050] A rotating rod 55 is rotatably connected to the lower end of the processing table 1. The upper end of the rotating rod 55 extends to the upper end of the processing table 1 and is fixedly connected to a rotating seat 56. The lower end of the rotating seat 56 is rotatably connected to the processing table 1. The lower end of the rotating rod 55 is rotatably connected to the inner surface of the outer shell 53. A one-way shaft is fixedly connected to the lower end of the rotating shaft 51. A belt drive mechanism 54 is rotatably connected to the outer surface of the one-way shaft. The end of the belt drive mechanism 54 away from the one-way shaft is fixedly connected to the rotating rod 55.

[0051] After the plasma cutting machine 24 has finished cutting all four sides of the steel plate, the hydraulic control device 31 drives the lifting plate 32 and guide bead 57 to rise. Initially, the guide bead 57 will move on the straight line at the bottom of the guide groove 52. When the guide bead 57 moves to the bottom of the arc-shaped part of the guide groove 52, the pressing plate 38 completely separates from the steel plate. At this time, the lifting plate 32 drives the guide bead 57 to continue to rise, so that the guide bead 57 slides on the arc-shaped part of the guide groove 52, thereby driving the rotating shaft 51 to rotate 45 degrees clockwise. This further drives the one-way shaft, belt drive mechanism 54, and rotating rod 55 to rotate synchronously, and finally drives the rotating seat 56 to rotate 45 degrees, so that the cut steel plate rotates synchronously, so that the four rectangular right angles of the steel plate are aligned with the cutting position of the plasma cutting machine 24, and then a second cutting is performed. At this time, it is only necessary to use the lifting component 3 and the moving component 4 to repeat the above pressing and cutting steps of the steel plate and its four sides to cut off the four corner triangles at the same time. The angles and dimensions of the four chamfers are completely symmetrical.

[0052] Furthermore, when the guide bead 57 moves to the upper end of the arc-shaped part of the guide groove 52, the rotating seat 56 drives the steel plate to rotate and then the lifting plate 32 is lowered, and the steel plate is pressed and limited again.

[0053] Among them, the one-way shaft mentioned above can only rotate clockwise with the rotating shaft 51. When the guide bead 57 descends with the lifting plate 32, it will drive the rotating shaft 51 to rotate counterclockwise. In this state, the one-way shaft and the belt drive mechanism 54 remain stationary, and the rotating seat 56 will not rotate.

[0054] The unloading assembly 6 includes a connecting plate 61 fixedly connected to the rear end of the lifting plate 32. A connecting column 62 is fixedly connected to the lower end of the connecting plate 61. A sliding groove 63 is provided at the upper end of the processing table 1. An movable groove 64 is provided at the upper end of the processing table 1 and to the right of the sliding groove 63. A sliding block 65 is slidably connected to the inner surface of the sliding groove 63. A push plate 66 is fixedly connected to the upper end of the sliding block 65. The outer surface of the push plate 66 is slidably connected to the empty groove 12 located at the rear.

[0055] The rear end of the push plate 66 is fixedly connected to the guide rod 67, and the inner surface of the movable groove 64 is slidably connected to the lifting plate 68. The left end of the lifting plate 68 is provided with the guide groove 681, and the outer surface of the guide rod 67 is slidably connected to the guide groove 681.

[0056] The upper end of the lifting plate 68 is provided with a movable groove 69, and the lower end of the connecting column 62 is fixedly connected with a locking block 621. The outer surface of the locking block 621 is slidably connected to the movable groove 69.

[0057] After the steel plate has been completely cut on all four sides and four corners, the hydraulic device 31 continues to control the lifting plate 32 and guide ball 57 to rise. Similarly, the connecting plate 61 and connecting column 62 rise synchronously. When the guide ball 57 rises to the upper end of the arc-shaped part of the guide groove 52, the locking block 621 moves to the uppermost end of the movable groove 69. At this time, the lifting plate 32 continues to rise, the guide ball 57 moves in the straight part of the upper part of the guide groove 52, and the connecting column 62 will drive the lifting plate 68 to rise as a whole, so that the guide rod 67 slides in the guide groove 681, thereby pushing the guide rod 67 and the push plate 66 to move forward as a whole, pushing the cut steel plate forward. There is no need for the operator to reach into the cutting station to pick up the material, which completely isolates the operator from direct contact with the high-temperature cutting area and the moving mechanism, and realizes the inherent safety of the processing process.

[0058] Furthermore, the feeding action is triggered only when all cutting processes are completed and the guide bead 57 moves to the upper straight section of the guide groove 52, thus preventing premature feeding and pushing of materials before processing is completed, and ensuring the finished product qualification rate.

[0059] Therefore, in the lifting and rotating process of the lifting component 3, this solution can both limit the steel plate using the pressing plate 38 and drive the four plasma cutting machines 24 to move synchronously along the rectangular track 22 through the rotation of the L-shaped connecting rod 42. This allows for the synchronous cutting of the four sides of the steel plate without manual operation, avoiding errors caused by manual operation and significantly improving cutting efficiency. At the same time, the lifting stroke of the lifting component 3 can be linked with the guide groove 52 and the guide bead 57 to drive the rotating seat 56 to rotate, thus achieving the 45-degree rotation of the steel plate without additional drive, successfully completing the chamfering of the four corners and seamlessly connecting multiple cutting processes. Finally, the lifting plate 32 continues to rise, triggering the push plate 66 to push the finished steel plate for unloading. The entire process requires no manual intervention for material transfer and unloading, integrating the dispersed processes and eliminating the risk of high-temperature operation, further optimizing the processing flow, ensuring the consistency of specifications of workpieces in the same batch, and adapting to the batch processing needs of iron tower steel plates.

[0060] It should be noted that the specific installation method, circuit connection method, and control method of the plasma cutting machine 24, hydraulic device 31, and motor 34 used in this invention are all conventional designs, and will not be described in detail in this invention.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
