Description

Technical Field

[0001] This invention belongs to the field of angle steel bending technology, specifically an angle steel bending device for steel structure construction. Background Technology

[0002] In traditional steel structure construction, angle steel, as an important load-bearing and connecting material, directly affects the stability and safety of the entire structure due to the accuracy of its shape. Currently available angle steel bending equipment mostly uses mechanical or hydraulic drives, bending angle steel through molds. While these devices can complete basic bending tasks, they have limitations in terms of ease of operation, bending accuracy, and adaptability to angle steel of different specifications. For example, when handling large or high-strength angle steel, some equipment may result in inaccurate bending angles or surface damage due to uneven force distribution or insufficient precision control. Furthermore, existing equipment typically requires professional operation, and adjusting the molds to accommodate different angle steel specifications is cumbersome, impacting construction efficiency.

[0003] However, existing angle steel bending devices for steel structure construction often have some problems in actual use: the existing angle steel bending process usually involves heating the angle steel before transferring it to the bending point and bending it with a hydraulic press. During this process, the heated angle steel will continuously react with oxygen in the air to form iron oxide. After being squeezed by the hydraulic press, the outer side of the iron oxide will fall off, resulting in a decrease in the surface roughness of the angle steel. This requires subsequent grinding, which increases the number of work steps, increases the working pressure, and seriously affects the processing efficiency. Summary of the Invention

The first fixing block is fixedly connected to the first U-shaped support plate. A rotating block is provided on one side of the first fixing block. The output end of the second drive motor passes through the second drive motor and is fixedly connected to the rotating block. The output end of the second drive motor is rotatably connected to the first fixing block. A sliding column is movably sleeved inside the rotating block.

[0013] The beneficial effects of this invention are as follows:

[0014] 1. This invention starts a first drive motor, which drives a first rotating shaft to rotate, which in turn drives a grinding wheel to rotate. At the same time, the rotation of the first rotating shaft drives a rotating disk to perform a 90° reciprocating oscillation. During this reciprocating oscillation, the rotating disk drives the first bushing, dustproof shell, fourth rotating shaft, and grinding wheel to reciprocate, so that the grinding wheel can conform to the bending angle of the first angle steel for grinding, thereby better removing the iron oxide formed on the surface, improving the color and appearance, improving product quality, and reducing equipment wear and failure rate, thereby reducing maintenance costs and downtime.

[0015] 2. This invention activates a second drive motor, which rotates the sliding column. The rotation of the sliding column causes the connecting column to move left and right. The movement of the connecting column causes the second bushing to move along the fixed rod. At this time, the connecting shaft, the L-shaped push plate, and the push head move synchronously. The left and right movement of the connecting column, along with the movement of the connecting column, causes the second bushing to move along the fixed rod. This synchronous movement of the connecting shaft, the L-shaped push plate, and the push head pushes out the first angle steel. This effectively avoids manual handling during the operation, improves work efficiency, and prevents the heated first angle steel from injuring the handling personnel.

[0016] 3. This invention starts a second drive motor, which drives the sliding column to rotate. The rotation of the sliding column drives the L-shaped push plate and the push head to move, thereby pushing the first angle steel. By limiting the movement distance of the push head, the push head is fixed to push the first angle steel, which effectively avoids the deviation of the heating position and the bending position caused by manual operation, thereby improving accuracy and consistency, reducing adjustment and preparation time, and improving production efficiency.

An internally fixed drive motor 12 is connected to the bending table 1. The output end of the first drive motor 12 is fixedly connected to a first rotating shaft 13. A first gear 14 is fixedly connected to the outside of the first rotating shaft 13. Two second rotating shafts 15 are respectively arranged on both sides of the first gear 14. A second gear 16 is fixedly connected to the outside of each of the two second rotating shafts 15. Both second gears 16 are meshed with the first gear 14. A third rotating shaft 17 is arranged on one side of each of the two second gears 16. The second rotating shafts 15 and the third rotating shafts 17 are rotatably connected to the bending table 1. A third gear 18 is fixedly connected to the outside of each of the two third rotating shafts 17. The two third gears 18 are respectively meshed with the two second gears 16.

A grinding component is provided at the top of the bending table 1. A push component is provided on one side of the bottom of the bending table 1. The grinding component includes a dustproof shell 23. The dustproof shell 23 is fixedly connected to the top of the first bushing 22. The first bushing 22 is rotatably connected to the first rotating shaft 13. A first bevel gear 24 is fixedly connected to the top of the first rotating shaft 13.

A fourth rotating shaft 26 is fixedly connected to one side of the second bevel gear 25, and a grinding wheel 27 is fixedly connected to the outside of the fourth rotating shaft 26. When the first drive motor 12 is started, the first drive motor 12 drives the first rotating shaft 13 to rotate, which in turn drives the grinding wheel 27 to rotate. At the same time, the rotation of the first rotating shaft 13 drives the rotating disk 21 to perform a 90° reciprocating oscillation. At this time, the reciprocating oscillation of the rotating disk 21 drives the first bushing 22, the dustproof shell 23, the fourth rotating shaft 26, and the grinding wheel 27 to reciprocate, so that the grinding wheel 27 can fit the bending angle of the first angle steel 5 to perform grinding, thereby better removing the iron oxide formed on the surface, improving the color and appearance, improving product quality, and reducing equipment wear and failure rate, thereby reducing maintenance costs and downtime.

[0028] The driving component includes a first U-shaped support plate 42, which is fixedly connected to one side of the bottom of the bending table 1. A second drive motor 28 is fixedly connected to the inner side of the first U-shaped support plate 42. A first fixing block 29 is fixedly connected to one side of the second drive motor 28. The first fixing block 29 is fixedly connected to the first U-shaped support plate 42. A rotating block 30 is provided on one side of the first fixing block 29. The output end of the second drive motor 28 passes through the second drive motor 28 and is fixedly connected to the rotating block 30. The output end of the second drive motor 28 is connected to the first fixing block 28. 9. A rotating connection is established, in which a sliding post 31 is movably sleeved inside the rotating block 30, and a spring 32 is sleeved on the outside of the sliding post 31. A second fixing block 33 is fixedly connected to one end of the sliding post 31, and the other end of the sliding post 31 is fixedly connected to the rotating block 30. A connecting shaft 34 is rotatably connected to the middle of one side of the second fixing block 33, and a third fixing block 35 is provided on one side of the second fixing block 33. The connecting shaft 34 and the third fixing block 35 are threadedly connected. The pushing assembly includes a connecting post 36, which is fixedly connected to the third fixing block 35. At the top center of block 35, a second bushing 37 is fixedly connected to the top of the connecting column 36. A fixing rod 38 is provided in the middle of the second bushing 37. The second bushing 37 is movably sleeved on the outside of the fixing rod 38. A fourth fixing block 39 is fixedly connected to both sides of the fixing rod 38. The fourth fixing block 39 is fixedly connected to the bending table 1. An L-shaped push plate 40 is fixedly connected to one side of the third fixing block 35. A push head 41 is fixedly connected to one side of the top of the L-shaped push plate 40. By starting the second drive motor 28, the second drive motor 28 drives the sliding column 31 to rotate. 1. Rotation drives the connecting column 36 to move left and right. The movement of the connecting column 36 drives the second bushing 37 to move along the fixed rod 38. At this time, the connecting shaft 34, the L-shaped push plate 40 and the push head 41 move synchronously. The connecting column 36 moves left and right, and the movement of the connecting column 36 drives the second bushing 37 to move along the fixed rod 38. At this time, the connecting shaft 34, the L-shaped push plate 40 and the push head 41 move synchronously, thereby pushing out the first angle steel 5. In the process of working, manual handling is effectively avoided, work efficiency is improved, and the heated first angle steel 5 is prevented from causing injury to the handling personnel.

[0029] Among them, cylindrical protrusions are fixedly connected to the top of the two guide rods 20 near the rotating disk 21. The height of the cylindrical protrusions is equal to the height of the rotating disk 21. The slots and arc positions of the rotating disk 21 correspond to the guide rods 20 and the fan-shaped push blocks 19, respectively. The rotation of the fan-shaped push blocks 19 on both sides and the guide rods 20 can drive the rotating disk 21 to swing back and forth by 90°, so that the grinding wheel 27 can grind the bent parts to remove iron oxide and improve product quality.

[0030] The guide plate 4 has a push groove 44 inside, which connects the guide plate 4 and the bending table 1. The positions of the L-shaped push plate 40 and the push head 41 correspond to the push groove 44. The corresponding positions of the push groove 44 and the push head 41 enable the push head 41 to better push the first angle steel 5 during the movement, accurately reach the bending point, and complete the bending.

[0031] The grinding wheel 27 has an inclination angle of 45°, which corresponds to the first angle steel 5 after bending. There is a gap between the bending block 11 and the supporting circular plate 9, and the size of the gap is the width of the first angle steel 5. The guide plate 4 has a groove corresponding to the L-shaped heating plate 2, and there is a gap between the groove and the L-shaped heating plate 2, with a gap size of 2mm. The size of the gap between the bending block 11 and the supporting circular plate 9 is the same as the width of the first angle steel 5, which allows it to be inserted into the gap during the pushing process to prevent displacement and improve the bending effect.

[0032] Working principle:

[0033] During operation, the first angle steel 5 is placed on the surface of the guide plate 4. At this time, the second drive motor 28 is started, causing the rotating block 30 to rotate. The rotation of the rotating block 30 causes the sliding column 31 to rotate, which in turn causes the second fixed block 33 to rotate. Simultaneously, the rotation of the sliding column 31 causes the second fixed block 33 to move. Due to the limiting effect of the connecting column 36, the second fixed block 33 moves left and right along the rotation diameter of the sliding column 31, following its rotation. The movement of the second fixed block 33 causes the third fixed block 35 to slide up and down along the connecting column 36. While the third fixed block 35 is sliding, the lateral force generated by the rotation of the sliding column 31 causes the connecting column 36 to move left and right. The second bushing 37 moves along the fixed rod 38. At this time, the connecting shaft 34, the L-shaped push plate 40 and the push head 41 move synchronously. When the second bushing 37 moves to the leftmost end of the fixed rod 38, the top of the third fixed block 35 is in contact with the bottom of the second bushing 37, and the spring 32 is stretched. At this time, the sliding column 31 continues to rotate, and the second fixed block 33 can no longer drive the third fixed block 35 to rise. The spring 32 will then be compressed, and the rotation of the third fixed block 35 will turn into lateral movement. The lateral movement of the third fixed block 35 will drive the L-shaped push plate 40 and the push head 41 to move laterally, thereby pushing out the first angle steel 5. In the process of working, manual handling is effectively avoided, improving work efficiency, and at the same time avoiding injury to the handling personnel caused by the heated first angle steel 5.

[0034] After the first angle steel 5 is pushed to the appropriate position, the hydraulic rod 6 is activated. The hydraulic rod 6 drives the bending head 7 to move, which in turn moves the first angle steel 5. During this movement, the bottom surface of the first angle steel 5 engages with the slots of the supporting circular plate 9 and the fixing column 10. At this point, the fixing column 10 is in contact with the surface of the first angle steel 5. As the hydraulic rod 6 continues to push, the first angle steel 5 can be bent. After bending, the first drive motor 12 is activated, which drives the first rotating shaft 13 to rotate. The rotation of the first rotating shaft 13 drives the first bevel gear 24 to rotate, which in turn drives the second bevel gear 25 to rotate. The rotation of the second bevel gear 25 drives the fourth rotating shaft 26 and the grinding wheel 27. The first rotating shaft 13 rotates, driving the second gear 16, the third gear 18, the sector push block 19, and the guide rod 20 to rotate. Since the sector push blocks 19 and the guide rod 20 on the left and right sides are staggered at 90°, the rotating disk 21 will be driven to perform a 90° reciprocating swing motion during the rotation. At this time, the reciprocating swing of the rotating disk 21 drives the first bushing 22, the dustproof shell 23, the fourth rotating shaft 26, and the grinding wheel 27 to reciprocate, so that the grinding wheel 27 can fit the bending angle of the first angle steel 5 for grinding, thereby better removing the iron oxide formed on the surface, improving the color and appearance, improving product quality, and reducing equipment wear and failure rate, thereby reducing maintenance costs and downtime.
