Description

Technical Field

[0001] The invention belongs to the technical field of angle steel bending, and in particular relates to an angle steel bending device for steel structure construction. Background Art

[0002] In traditional steel structure construction, angle steel is an important load-bearing and connecting material, and the accuracy of its shape directly affects the stability and safety of the entire structure. Most of the angle steel bending equipment currently available on the market uses mechanical or hydraulic drive methods to bend the angle steel through molds. Although these devices can complete basic bending tasks, they are limited in terms of ease of operation, bending accuracy, and the ability to adapt to angle steels of different specifications. For example, when some equipment is processing large-sized or high-strength angle steels, due to uneven force distribution or insufficient control, it is easy to cause inaccurate bending angles or damage to the surface of the angle steel. In addition, the equipment of the prior art usually requires professional operation, and the process of adjusting the mold to adapt to angle steels of different specifications is cumbersome, which affects the construction efficiency.

[0003] However, the existing angle steel bending devices for steel structure construction often have some problems during actual use: the existing angle steel bending process usually involves heating the bending part of the angle steel, then transferring it to the bending part and performing the bending operation using a hydraulic press. During this process, the heated angle steel will continuously react with oxygen in the air to form iron oxide, which will cause the outer side of the iron oxide to fall off after being squeezed by the hydraulic press, thereby reducing the surface roughness of the angle steel and requiring subsequent grinding, which increases the work steps, increases the work pressure and seriously affects the processing efficiency.

At this time, the connecting shaft 34, the L-shaped pushing plate 40 and the pushing head 41 move synchronously to move the connecting column 36 left and right, and the movement of the connecting column 36 drives the second sleeve 37 to move along the fixed rod 38. At this time, the connecting shaft 34, the L-shaped pushing plate 40 and the pushing head 41 move synchronously, thereby pushing out the first angle steel 5, effectively avoiding manual handling during the work process, improving work efficiency, and preventing the heated first angle steel 5 from causing harm to the handling personnel.

[0021] Among them, the two guide rods 20 are fixedly connected with cylindrical protrusions on the top of one side close to the rotating disk 21. The height of the cylindrical protrusion is equal to the height of the rotating disk 21. The slot and arc position 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 and the guide rods 20 on both sides can drive the rotating disk 21 to swing back and forth 90°, so that the grinding wheel 27 grinds the bending part to remove iron oxide and improve product quality.

[0022] Among them, a pushing groove 44 is opened inside the guide plate 4, and the pushing groove 44 connects the guide plate 4 and the bending table 1. The positions of the L-shaped pushing plate 40 and the pushing head 41 correspond to the pushing groove 44. The corresponding positions of the pushing groove 44 and the pushing head 41 enable the pushing head 41 to better push the first angle steel 5 during the movement, accurately reach the bending position, and complete the bending.

[0023] Among them, the inclination angle of the grinding wheel 27 is 45°, and the inclination angle of the grinding wheel 27 is set corresponding 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 is provided with a groove corresponding to the L-shaped heating plate 2, and a gap is left between the groove and the L-shaped heating plate 2. The size of the gap is 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 can enable it to be stuck in the gap during the pushing process to prevent displacement, thereby improving the bending effect.

[0024] Working principle: During the working process, the first angle steel 5 is placed on the surface of the guide plate 4, and the second driving motor 28 is started. The second driving motor 28 starts to drive the rotating block 30 to rotate, and the rotating block 30 rotates to drive the sliding column 31 to rotate. The sliding column 31 rotates to drive the second fixed block 33 to rotate. At the same time, the second fixed block 33 moves due to the rotation of the sliding column 31, and due to the limitation of the connecting column 36, the second fixed block 33 will follow the rotation of the sliding column 31 and move left and right along the rotation diameter of the sliding column 31. The movement of the second fixed block 33 drives the third fixed block 35 to slide up and down along the connecting column 36. When the third fixed block 35 slides, the lateral force generated by the rotation of the sliding column 31 will drive the connecting column 36 to move left and right, and the connecting column 36 moves The second sleeve 37 is driven to move along the fixing rod 38. At this time, the connecting shaft 34, the L-shaped pushing plate 40 and the pushing head 41 move synchronously. When the second sleeve 37 moves to the leftmost end of the fixing rod 38, the top of the third fixing block 35 is fitted with the bottom of the second sleeve 37, and the spring 32 is stretched. At this time, the sliding column 31 continues to rotate, and the second fixing block 33 cannot continue to drive the third fixing block 35 to rise. The spring 32 will be compressed at this time, and the rotation of the third fixing block 35 will be converted into lateral movement. The lateral movement of the third fixing block 35 drives the L-shaped pushing plate 40 and the pushing head 41 to move laterally, thereby pushing out the first angle steel 5. In the working process, manual handling is effectively avoided, and work efficiency is improved. At the same time, the heated first angle steel 5 is prevented from causing harm to the handling personnel. After the first angle steel 5 is pushed to a suitable position, the hydraulic rod 6 is started, and the hydraulic rod 6 is started to drive the bending head 7 to move, and the bending head 7 moves to push the first angle steel 5 to move. During the movement, the bottom surface of the first angle steel 5 is inserted into the groove of the supporting circular plate 9 and the fixed column 10. At this time, the fixed column 10 fits with the surface of the first angle steel 5. After the hydraulic rod 6 continues to push, the first angle steel 5 can be bent. After bending, the first drive motor 12 is started, and the first drive motor 12 is started to drive the first rotating shaft 13 to rotate. The rotation of the first rotating shaft 13 drives the first bevel gear 24 to rotate. The rotation of the first bevel gear 24 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, and at the same time, the second gear 16, the third gear 18, the fan-shaped push block 19 and the guide rod 20 rotate. Since the fan-shaped 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 sleeve 22, the dustproof housing 23, the fourth rotating shaft 26 and the grinding wheel 27 to swing back and forth, so that the grinding wheel 27 can fit the bending angle of the first angle steel 5 for grinding, so as to better remove the iron oxide formed on the surface, thereby improving the color and appearance, improving product quality, and reducing equipment wear and failure rate, thereby reducing maintenance costs and downtime.
