Description

Technical Field

[0001] This invention relates to the field of processing and conveying technology, specifically to an integrated processing device for marking, hole making, and corner cutting of angle steel tower components. Background Technology

[0002] As the core support structure of power transmission lines, the processing quality of angle steel components in angle steel towers directly affects the load-bearing capacity and service life of the towers. In the processing flow of angle steel components for angle steel towers, marking (identifying component information), hole making (processing bolt connection holes), and corner cutting (end forming) are the three key processes that determine the interchangeability and connection strength of the components.

[0003] In actual use, the existing angle steel tower angle steel component processing equipment can transport the marked angle steel components to the subsequent hole making or corner cutting station through the conveyor roller to realize the basic assembly line operation function, but its conveying and positioning mechanism has significant defects. When angle steel components detach from the buffer plate and enter the next process, traditional devices rely solely on the friction of the cutting rollers to propel the workpiece forward. Since angle steel tower components are mostly large-section, ultra-long, heavy angle steel with extremely high weight, relying solely on friction to drive them is prone to causing jamming or scraping due to insufficient power at the moment of detachment from the buffer plate. This not only disrupts the smoothness of material flow but also leaves scratches on the workpiece surface, affecting the subsequent galvanizing quality and appearance. More seriously, when the heavy steel components are transported away, the placement rack tends to return to its original position due to the sudden reduction in weight. Traditional devices lack an effective instant locking mechanism, causing the placement rack to bounce upward under the action of the elastic element, directly impacting the bottom of the moving steel component. This results in uneven table surfaces, leading to frequent changes in the processing reference surface. The already prepared holes shift during the impact, ultimately causing the hole spacing error of the same batch of angle steel components to significantly exceed the standard allowable range, seriously affecting the interchangeability and fastening strength of the tower assembly on site. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an integrated processing device for marking, drilling, and corner cutting of angle steel tower components, which solves the problems mentioned in the background section.

[0010] The buffer device further includes a slide rod 2 that slides on the inner wall of the processing table, a baffle that slides on the surface of the processing table, a rotating plate that is rotatably connected to the processing table, a sliding plate that is slidably connected to the processing table, a positioning block that is fixedly connected to the processing table, and a sliding key that slides on the inner wall of the positioning block. The sliding plate has a slot on the side near the sliding key, and the baffle has a groove on the side near the slide rod 2. The slide rod 2 is fixedly connected to the placement frame.

[0011] The surface of the pressure block is sloped to allow it to move when the steel part moves.

[0012] The fixing device includes a rotating frame rotatably connected to the placement frame, a gear plate fixedly connected to the rotating shaft of the rotating frame, a gear plate fixedly connected to the processing table, a pressure rod sliding on the inner wall of the rotating frame, and a pressure plate fixedly connected to the pressure rod.

[0014] An elastic element is provided between the pressure plate and the rotating frame, a torsion spring is provided between the rotating frame and the placement frame, the side of the second pressure block near the sliding pressure block is set as an inclined surface, and an elastic element is provided between the pressing frame and the rotating frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In this invention, the teeth on the surface of the rotating roller apply a tangential frictional force to the steel workpiece in the same direction as the conveying direction. This design converts the workpiece's own gravitational potential energy into an auxiliary rolling driving force, effectively preventing the steel workpiece from getting stuck or scraped when it leaves the buffer plate, ensuring the smoothness of material flow. When the steel workpiece moves and contacts the arc surface of the pressure rod, it will press down on the pressure rod, and push the insertion rod directly into the placement frame through the inclined plane action. At the moment when the heavy steel workpiece is conveyed away, the placement frame tends to reset upward due to the weight reduction. This design triggers locking synchronously at the moment the conveying action occurs, completely avoiding the placement frame from hitting the bottom of the moving steel workpiece upward due to elastic reset, thereby eliminating the instability of the processing reference surface or the displacement of the hole position caused by the undulation of the table surface.

[0017] 2. In this invention, when the steel part reaches the buffer plate and presses the placement rack down, the slide bar moves and releases the obstruction to the pressing device. If the steel part in front has not been processed, even if the push plate drives the next steel part to rise, it cannot contact the baffle to complete the rotation and pushing. This effectively prevents the subsequent steel parts from being forcibly pushed in before the hole-making process is completed, causing workpiece collision, equipment overload, or processing datum disorder. It fundamentally eliminates product scrap or equipment damage caused by the disorder of the cycle. When the steel part moves toward the buffer plate, it will first contact the rotating plate. The rotating plate presses down on the sliding plate. The sliding friction between the inclined surface of the sliding key and the slot, together with the elastic element of the sliding plate itself, absorbs the horizontal kinetic energy of the steel part, which significantly reduces the lateral impact force of the steel part on the buffer plate and the placement rack, effectively protecting the surface finish of the workpiece and the positioning accuracy of the equipment.

[0018] 3. In this invention, when the placement frame moves downward due to the support of the steel part, it drives the rotating frame to move downward. Then, through the meshing of the gear plate and the rack, the rotating frame is driven to rotate, causing the pressing rod to automatically swing to the ready position to contact the surface of the steel part. The mechanical force ensures that the hole-making tool always maintains the correct spatial posture with the workpiece, avoiding hole position deviation caused by manual alignment or electronic control delay. It is especially suitable for frequent production change scenarios of multi-specification angle steel. When the output end of the pressing device extends, the fixed plate is driven to contact and press the steel part first through the linkage of the pressing frame. After the steel part is completely fixed, the pressing rod continues to press down to make holes. This effectively prevents the steel part from vibrating, slipping or flange turning outward due to cutting force at the moment of hole making, fundamentally ensuring the hole diameter accuracy and hole wall surface roughness, and avoiding quality defects such as drill breakage or hole tearing caused by unstable clamping.

[0033] Please see Figures 1-11 One embodiment of the present invention is: an integrated processing device for marking, hole making, and corner cutting of angle steel tower components, including an operating table 1, a processing table 2, a marking device 3 disposed on the surface of the processing table 2, a conveying roller 4 disposed on the inner wall of the marking device 3, a pressing device 5 disposed on the surface of the conveying roller 4, a placement frame 6 sliding on the inner wall of the processing table 2, a cutting roller 7 disposed on the inner wall of the processing table 2, and a fixed table 15 fixedly connected to the processing table 2.

[0034] The moving device includes a buffer plate 8 disposed on the surface of the placement frame 6, a gear disk 10 disposed at the bottom of the processing table 2, a fixed frame 9 disposed on the inner wall of the placement frame 6, and a rotating roller 11 rotating on the inner wall of the fixed frame 9. A power source is disposed at the bottom of the processing table 2, and the output end of the power source is fixedly connected to the gear disk 10. The surface of the rotating roller 11 is provided with teeth, and the rotating roller 11 matches the gear disk 10.

[0035] The moving device also includes a slide rod 12 that slides on the inner wall of the placement rack 6, a sliding rod 13 that slides on the inner wall of the placement rack 6, an insertion rod 14 that slides on the inner wall of the placement rack 6, a pressure rod 16 that slides on the inner wall of the fixed platform 15, and an insertion rod 17 that is provided on the inner wall of the fixed platform 15. The slide rod 12 has a sliding groove on the side near the sliding rod 13, and the processing table 2 has a slot on the side near the insertion rod 14. The insertion rod 14 contacts the inner wall of the slot, and the placement rack 6 has a slot on the side near the insertion rod 17.

[0036] An elastic element is provided between the buffer plate 8 and the placement frame 6. The elastic element is provided to drive the buffer plate 8 to reduce the impact force of the steel parts. The side of the slide rod 12 near the buffer plate 8 is set with an inclined surface. The inclined surface is provided to push the slide rod 12 to move. The side of the sliding groove near the sliding rod 13 is set with an inclined surface. The inclined surface of the sliding groove is provided to push the sliding rod 13 to move upward during reset. An elastic element is provided between the slide rod 12 and the placement frame 6. The elastic element is provided to drive the slide rod 12 to reset. The side of the sliding rod 13 near the insertion rod 14 is set with an inclined surface. The inclined surface is provided to push the insertion rod 14 to reset. An elastic element is provided between the insertion rod 14 and the placement frame 6. The elastic element is provided to drive the insertion rod 14 to disengage from the processing table 2. The side of the pressure rod 16 near the insertion rod 17 is set with an inclined surface. An elastic element is provided between the insertion rod 17 and the fixed table 15. The elastic element is provided to drive the insertion rod 17 to reset. The side of the pressure rod 16 near the placement frame 6 is set with an arc surface.

[0037] In this embodiment, during operation: When processing of the steel part is required, the steel part is carried by the conveying roller 4 through the inside of the marking device 3. Marking is performed on the steel part as it passes the bottom of the marking device 3. After marking, the steel part is conveyed to the surface of the placement rack 6. After movement, the output end of the motor inside the pressing device 5 extends to open a hole on the surface of the steel part. After opening the hole, the cutting roller 7 moves the steel part. The moving steel part contacts the inside of the fixed table 15, whereby the fixed table 15 grinds the burrs on the surface of the steel part. When the steel part moves to the surface of the placement rack 6, it contacts the buffer plate 8. The elastic elements inside the buffer plate 8 and the fixed rack 9 reduce the impact generated when the steel part is placed. When the buffer plate 8 is pressed by the steel part, it moves downwards. When the buffer plate 8 moves, the fixed rack 9... When the rotating roller 11 extends, it will contact the surface of the steel part. When the buffer plate 8 moves downward, it will contact the inclined surface of the slide rod 12. The buffer plate 8 will then push the slide rod 12 towards the sliding rod 13. As the slide rod 12 moves, it will drive the sliding groove to move. When the sliding groove moves to the bottom of the slide rod 13, the slide rod 13 will be driven by the elastic element to move into the sliding groove. At this time, the obstruction of the slide rod 13 to the insertion rod 14 will be released. The insertion rod 14 will then be driven by the elastic element to move into the placement frame 6, releasing the limit between the placement frame 6 and the processing table 2. The placement frame 6 can slide downward under the weight of the steel part. When the placement frame 6 slides downward, it will drive the fixed frame 9 to move. The movement of the fixed frame 9 will drive the rotating roller 11 to move. The downward movement of the rotating roller 11 will... When the rotating roller 11 contacts the gear disk 10, its teeth will match the gear disk 10. When the gear disk 10 rotates, it can drive the rotating roller 11 to rotate. When the rotating roller 11 rotates, it can help push the steel part away from the surface of the buffer plate 8. When the steel part moves, it will contact the arc surface of the pressure rod 16. The steel part will press the pressure rod 16 to move downward. The downward movement of the pressure rod 16 will push the second insertion rod 17 towards the placement frame 6. Then the second insertion rod 17 will be inserted into the placement frame 6 to fix the placement frame 6, preventing the placement frame 6 from returning to its original position due to the reduced weight, which would affect the smooth operation of the steel part. When the steel part rolls from the conveying roller 4 onto the surface of the placement frame 6, the elastic element inside the buffer plate 8 and the fixed frame 9 will absorb the weight of the falling part. The impact potential energy not only avoids scratches or deformation on the steel surface caused by hard landing, but also protects the flatness of the subsequent processing reference surface and reduces internal stress micro-cracks caused by impact. When the steel part presses down on the buffer plate 8, it triggers the sliding rod 12 to translate, which in turn releases the sliding rod 13 from blocking the insertion rod 14, causing the mechanical limit of the placement frame 6 and the processing table 2 to automatically fail. The downward movement of the placement frame 6 drives the rotating roller 11 to mesh with the gear disk 10. When the gear disk 10 rotates, the teeth on the surface of the rotating roller 11 apply a tangential frictional force to the steel part in the same direction as the conveying direction. This design converts the gravitational potential energy of the workpiece itself into an auxiliary rolling driving force, effectively preventing the steel part from jamming or scratching when it leaves the buffer plate 8, and ensuring the smoothness of material flow.When the steel part moves and contacts the arc surface of the pressure rod 16, it presses down on the pressure rod 16. Through the action of the inclined plane, it pushes the insertion rod 17 directly into the placement frame 6. At the moment the heavy steel part is transported away, the placement frame 6, due to its reduced weight, tends to return to its original position. This design triggers locking simultaneously at the moment of transport, completely preventing the placement frame 6 from impacting the bottom of the moving steel part due to elastic return, thus eliminating instability of the machining reference surface or hole displacement caused by table undulations.

[0038] Please see Figures 1-11 Based on the above embodiments, in another embodiment of the present invention, the buffer device includes an electric push rod 21 disposed at the bottom of the processing table 2, a push plate 22 rotatably connected to the output end of the electric push rod 21, a pressure block 23 sliding on the inner wall of the push plate 22, and a limiting rod 24 sliding on the inner wall of the push plate 22. A positioning groove is provided on the side of the processing table 2 near the limiting rod 24, and a push groove is provided on the side of the pressure block 23 near the limiting rod 24.

[0039] The buffer device also includes a slide rod 26 that slides on the inner wall of the processing table 2, a baffle 25 that slides on the surface of the processing table 2, a rotating plate 27 that is rotatably connected to the processing table 2, a sliding plate 28 that is slidably connected to the processing table 2, a positioning block 29 that is fixedly connected to the processing table 2, and a sliding key 291 that slides on the inner wall of the positioning block 29. The sliding plate 28 has a slot on the side near the sliding key 291, and the baffle 25 has a groove on the side near the slide rod 26. The slide rod 26 is fixedly connected to the placement frame 6.

[0040] The surface of the pressure block 23 is inclined so that it can be pressed and moved when the steel part moves. An elastic element is provided between the pressure block 23 and the push plate 22 so that the pressure block 23 can be reset. An elastic element is provided between the limit rod 24 and the push plate 22 so that the limit rod 24 can be moved away from the processing table 2. An elastic element is provided between the baffle 25 and the processing table 2. An elastic element is provided between the sliding plate 28 and the processing table 2. A torsion spring is provided between the rotating plate 27 and the processing table 2 so that the rotating plate 27 can be reset. An elastic element is provided between the positioning block 29 and the sliding key 291 so that the sliding key 291 can be pushed to apply friction to the sliding plate 28. The side of the sliding key 291 near the sliding plate 28 is inclined.

[0041] The fixing device includes a rotating frame 31 rotatably connected to the placement frame 6, a gear plate 33 fixedly connected to the rotating shaft of the rotating frame 31, a gear plate 33 fixedly connected to the processing table 2, a pressing rod 35 sliding on the inner wall of the rotating frame 31, and a pressure plate 34 fixedly connected to the pressing rod 35.

[0042] The fixing device also includes a pressing frame 36 slidably connected to the rotating frame 31, a pressing block 37 fixedly connected to the pressing frame 36, a sliding pressing block 38 slidably connected to the rotating frame 31, a connecting rod 39 rotatably connecting the sliding pressing block 38 and the pressing plate 34, and a fixing plate 391 fixedly connected to the pressing frame 36.

[0043] An elastic element is provided between the pressure plate 34 and the rotating frame 31, a torsion spring is provided between the rotating frame 31 and the placement frame 6, the side of the pressure block 37 near the sliding pressure block 38 is set as an inclined surface, and an elastic element is provided between the pressing frame 36 and the rotating frame 31.

[0044] In this embodiment, during operation: after the steel part is marked, the conveyor roller 4 pushes the steel part to the surface of the push plate 22. When the steel part moves to the surface of the push plate 22, it will contact the inclined surface of the pressure block 23, causing the steel part to press the pressure block 23 downward. The downward movement of the pressure block 23 will drive the push groove to move, and the limiting rod 24 will slide inward towards the pressure block 23. The movement of the limiting rod 24 will release the contact between it and the processing table 2, and the limiting between the push plate 22 and the processing table 2 will be released. At this time, the push plate 22 can move upward. After the steel part has moved, the output end of the electric push rod 21 will push the push plate 22 to move. The movement of the push plate 22 will drive the steel part to move. When the push plate 22 moves, it will contact the baffle 25, and the push plate 22 will rotate. When the push plate 22 rotates, it will push the surface steel... The steel piece is pushed towards the buffer plate 8. When the steel piece presses against the surface of the buffer plate 8 and moves the placement bracket 6 downward, it will drive the slide rod 26 to move. The movement of the slide rod 26 will release the obstruction to the pressing device 5, and the pressing device 5 will move towards the pressure push plate 22. When the steel piece on the surface of the buffer plate 8 is not finished, the push plate 22 will drive the next steel piece to move upward and will not be able to contact the baffle 25. Only after the previous one is finished and detached from the surface of the buffer plate 8 can the push plate 22 contact the baffle 25. When the steel piece moves towards the buffer plate 8, it will contact the rotating plate 27. When the steel piece moves towards the buffer plate 8, it will press the rotating plate 27 to rotate downward. The downward movement of the rotating plate 27 will press the sliding plate 28 to slide downward. The downward movement of the sliding plate 28 will drive the slot to move. When the slot moves, it will contact the inclined surface of the sliding key 291. The friction generated when the sliding key 291 contacts the slot, along with the elasticity of the sliding plate 28, will reduce the impact of the steel part moving towards the buffer plate 8. When the steel part moves to the surface of the push plate 22, it presses the inclined surface of the pressure block 23, causing the limit rod 24 to automatically retract and release the limit between the push plate 22 and the processing table 2, thus enabling the push plate 22 to be lifted upwards. This ensures that the electric push rod 21 only starts lifting after the steel part is in place, avoiding empty pushing or jamming, and achieving seamless connection between the marking station and the transfer station. During the upward movement of the push plate 22, it rotates after contacting the baffle 25, pushing the steel part on the surface laterally towards the buffer plate 8. By rotating the pusher, the movement direction of the steel part is changed from vertical lifting to... Horizontal conveying cleverly utilizes the internal space of the equipment, allowing steel parts to enter the next processing station with a controllable posture and precision. This avoids end impact or deflection caused by straight-line pushing. When the steel part reaches the buffer plate 8 and presses the placement frame 6 downward, the slide bar 26 moves and releases the obstruction to the pressing device 5. If the preceding steel part has not yet been processed, even if the push plate 22 lifts the next steel part, it cannot contact the baffle 25 to complete the rotational pushing. This effectively prevents subsequent steel parts from being forcibly pushed in before the hole-making process is completed, causing workpiece collisions, equipment overload, or processing datum errors. It fundamentally eliminates product scrap or equipment damage caused by rhythm disorder. When the steel part moves towards the buffer plate 8, it will first contact the rotating plate 27, which presses down the sliding plate 28.By utilizing the sliding friction between the inclined surface of the sliding key 291 and the slot, combined with the elasticity of the sliding plate 28 itself, the horizontal kinetic energy of the steel component is absorbed, significantly reducing the lateral impact force of the steel component on the buffer plate 8 and the placement frame 6, effectively protecting the surface finish of the workpiece and the positioning accuracy of the equipment.

[0045] When the placement frame 6 moves downward, it drives the rotating frame 31 downward. The downward movement of the rotating frame 31 drives the gear plate 33 to move. When the gear plate 33 moves, it comes into contact with the rack 32, and the teeth between the gear plate 33 and the rack 32 engage. The rack 32 then pushes the gear plate 33 to rotate. The rotation of the gear plate 33 drives the rotating frame 31 to rotate, and the rotation of the rotating frame 31 drives the pressing rod 35 to move. The pressing rod 35 then comes into contact with the surface of the steel part. When it is necessary to make a hole in the steel part, the pressing device... The output end of device 5 extends and contacts the pressure plate 34. The output end of the pressing device 5 presses the pressing rod 35 towards the steel part through the pressure plate 34. When the pressure plate 34 moves, it pushes the sliding pressure block 38 to move through the connecting rod 39. The sliding pressure block 38 will contact the inclined surface of the second pressure block 37, and then the sliding pressure block 38 will press the second pressure block 37 to move downward. The movement of the second pressure block 37 will drive the fixing plate 391 to contact the steel part through the pressing frame 36. The contact between the fixing plate 391 and the steel part will fix the steel part. Once fixed, the output end of the pressing device 5 pushes the pressing rod 35 downwards continuously, causing the pressing rod 35 to drill a hole in the surface of the steel part. When the placement frame 6 moves downwards due to carrying the steel part, it drives the rotating frame 31 to move downwards. In turn, through the meshing of the gear plate 33 and the rack 32, the rotating frame 31 is driven to rotate, causing the pressing rod 35 to automatically swing to the ready position to contact the surface of the steel part. Mechanical force ensures that the drilling tool always maintains the correct spatial posture with the workpiece, avoiding delays caused by manual alignment or electrical control. Hole position deviation is particularly suitable for frequent production changes of multi-specification angle steel. When the output end of the pressing device 5 extends, the fixed plate 391 is driven to contact and press the steel part first through the linkage of the pressing frame 36. After the steel part is completely fixed, the pressing rod 35 continues to press down to make a hole. This effectively prevents the steel part from vibrating, slipping or flange turning outward due to cutting force at the moment of hole making. It fundamentally ensures the accuracy of the hole diameter and the surface roughness of the hole wall, and avoids quality defects such as drill breakage or hole tearing caused by unstable clamping.
