Description

Technical Field

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

[0002] The automated angle steel bending machine for steel structure construction is an efficient and precise mechanical equipment specially used to bend materials such as angle steel into the required shape and angle. The working principle of the automated angle steel bending machine is mainly based on the hydraulic system. The hydraulic system drives the slider to move downward, driving the mold to bend the angle steel. The process is characterized by high precision and high efficiency, which can greatly improve work efficiency and product quality.

[0003] After searching, the Chinese patent with publication number CN116786649A discloses a stainless steel angle steel bending mechanism, including a workbench, a bending mechanism for bending the stainless steel angle steel is installed on the workbench, a heating mechanism for heating the bent part of the stainless steel angle steel is installed on the workbench, two placement seats for placing the angle steel are relatively installed on the workbench, the bending mechanism is connected to the heating mechanism, a storage mechanism for collecting debris is provided on the protection mechanism, and an opening and closing mechanism is provided between the workbench and the bending mechanism; the above scheme can place the angle steel on the placement seat before bending the angle steel and heat it by the heating mechanism, and then transfer it to the bending mechanism for bending after heating, which is convenient for heating and transferring the angle steel, ensuring that the angle steel is folded at a specified temperature, improving the bending quality, and driving the heating mechanism to shrink to the inside of the workbench when the bending mechanism descends, so as to avoid the bending mechanism causing damage to the heating mechanism when bending the angle steel. However, the above scheme still has the following shortcomings in actual use: In the above scheme, the bending position of the angle steel needs to be heated before bending the angle steel to facilitate the deformation of the angle steel under stress.

In addition, the automatic unloading function significantly reduces the need for manual intervention, so that the angle steel can quickly and continuously enter the next process after bending; this not only shortens the production cycle, but also improves the fluency and efficiency of the overall production line; 3. The staff can simply adjust the position of the limit plate according to the actual size of the angle steel to ensure that the two ends of the angle steel can be in close contact with the corner position of the limit plate; this design enables the equipment to handle angle steels of various specifications without replacing or adjusting other complex components, greatly enhancing the adaptability and versatility of the equipment. In addition, by accurately adjusting the position of the limit plate, it can ensure that the angle steel maintains the correct position and posture during bending or processing, thereby reducing errors and the generation of defective products; this helps to improve production efficiency and product quality and meet more stringent processing requirements.

The reset structure includes: a fixed frame 41, which is fixed on the frame 1 and has an L-shaped structure; an outer cylinder 42, which is fixed to the side of the fixed frame 41 and has an open structure at one end; an inner rod 43, which is movably inserted in the outer cylinder 42 and has one end extending to the outside of the outer cylinder 42; a first spring 44, which has one end connected to the outer cylinder 42 and the other end connected to the inner rod 43; a push block 45, which is fixed to the end of the inner rod 43 located outside the outer cylinder 42, and is bent after During the bending process, when the bending head pushes the angle steel to move, the angle steel can contact with the push block 45 and push the push block 45 to move. When the push block 45 moves, it can drive the inner rod 43 to move, so that the inner rod 43 is retracted into the outer tube 42 and the first spring 44 is compressed. After the bending is completed, the bending head is reset under the action of the hydraulic cylinder 2. At this time, the angle steel lacks the extrusion of the bending head. Under the elastic force of the first spring 44, the inner rod 43 will also be reset, and drive the push block 45 to push the bent angle steel, so that the angle steel is also reset; The angle steel bending machine also includes two adjustment structures, both of which are arranged on the frame 1 and are used to provide position limiting for the angle steel. The adjustment structures include: two fixing plates 51, both of which are fixed on the side of the frame 1 and are arranged opposite to each other; an adjustment screw 52, ​​which is rotatably installed between the two fixing plates 51; a guide rod 53, which is fixed between the two fixing plates 51; an adjustment plate 54, which is threadedly sleeved on the adjustment screw 52 and slidably sleeved on the guide rod 53; a limit plate 55, which is fixed on the side of the adjustment plate 54 and has an L-shaped structure; and a plurality of convex strips 56, which are all fixed on the side of the limit plate 55; The angle steel bending machine also includes a lifting structure, which is arranged on the frame 1. The lifting structure includes: an opening 61, which is opened on the top surface of the frame 1; a servo cylinder 62, which is installed on the frame 1; a supporting plate 63, which is fixed on the output end of the servo cylinder 62 and is arranged opposite to the opening 61; The angle steel bending machine also includes an air jet structure, which is arranged on the frame 1, and the air jet structure includes: a cross bar 71, one end of which is fixed to the side of the frame 1; an air jet pipe 72, which is fixed to the other end of the cross bar 71; a plurality of first air jet ports 73, all of which are provided on the air jet pipe 72; a rotating sleeve 74, which is rotatably sleeved on the air jet pipe 72, and the inner ring of the rotating sleeve 74 and the outer surface of the air jet pipe 72 are mutually fitted; a plurality of second air jet ports 75, all of which are provided on the rotating sleeve 74, in an initial state, the plurality of second air jet ports 75 on the rotating sleeve 74 and the plurality of first air jet ports 73 on the air jet pipe 72 are in a mutually misaligned state, at which time the rotating sleeve 74 can block the plurality of first air jet ports 73, and the gas in the air jet pipe 72 cannot be ejected through the plurality of first air jet ports 73, so when the low-temperature gas enters the interior of the air jet pipe 72, it cannot be ejected through the plurality of first air jet ports 73, so that the air pressure inside the air jet pipe 72 increases; The angle steel bending machine also includes a driving structure, which is arranged on the frame 1. The driving structure is used to control the operation of the jet structure, and the driving structure is driven by the lifting structure. The driving structure includes: a connecting rod 81, one end of which is fixed to the bottom surface of the supporting plate 63; a rack 82, which is fixed to the other end of the connecting rod 81; a gear 83, which is fixedly sleeved on the rotating sleeve 74 and is arranged opposite to the rack 82. When the supporting plate 63 moves up, it can also drive the rack 82 to move upward through the connecting rod 81. When the rack 82 moves up, it can mesh with the gear 83 and drive the gear 83. 3 rotates, and the gear 83 can drive the rotating sleeve 74 to rotate. When the rack 82 is separated from the gear 83, the second jet ports 75 on the rotating sleeve 74 and the first jet ports 73 on the jet pipe 72 are aligned with each other. At this time, the low-temperature gas accumulated in the jet pipe 72 will be ejected through the second jet ports 75 and the first jet ports 73 that overlap with each other, and sprayed toward the angle steel on the supporting plate 63. The low-temperature gas can cool the high-temperature angle steel to prevent the high-temperature angle steel from scalding the staff; The angle steel bending machine also includes an air extraction structure, which is arranged on the frame 1. The air extraction structure is driven by the hydraulic cylinder 2. The air extraction structure includes: a mounting box 91, which is fixed on the top surface of the frame 1; a slideway 92, which is opened on the top surface of the mounting box 91; a slide plate 93, which is slidably arranged in the mounting box 91; a driving rod 94, one end of which is fixedly connected to the slide plate 93, and the other end is fixedly connected to the bending head. The driving rod 94 slides in the slideway 92; a second spring 95, one end of which is connected to the inner surface of the mounting box 91, and the other end is connected to the slide plate 93; a telescopic airbag 96, one end of which is connected to the inner surface of the mounting box 91, and the other end is connected to the slide plate 93; The angle steel bending machine also includes a cooling structure, which is arranged on the frame 1 and is used to cool the gas. The cooling structure includes: a cooling box 101, which is fixed on the top surface of the frame 1 and is arranged opposite to the mounting box 91, and the cooling box 101 has a cooling liquid stored inside; a mounting port 102, which is opened on the top surface of the cooling box 101; a semiconductor cooling sheet 103, which is installed in the mounting port 102, and the heat exchange surface of the semiconductor cooling sheet 103 faces the outside of the cooling box 101; a cooling pipe 104, which is fixed inside the cooling box 101 and One end of the cooling tube 104 immersed in the coolant is connected to the telescopic airbag 96; two mounting tubes 105, one end of the two mounting tubes 105 is connected to the other end of the cooling tube 104, and the other end extends to the outside of the cooling box 101, and the other end of one of the mounting tubes 105 is connected to the injection tube 72; two one-way valves 106 are respectively installed on the two mounting tubes 105, the bending head can drive the driving rod 94 to move, and the driving rod 94 drives the slide plate 93 to move when it moves. The slide plate 93 can stretch the telescopic airbag 96 during the movement, and the telescopic airbag 96 can perform a pumping action when it is stretched. For the cooling structure, the two one-way valves 106 installed on the two mounting tubes 105 have opposite flow limiting directions. Specifically, one of the one-way valves 106 limits the gas to only enter the interior of the cooling tube 104, and the other one-way valve 106 limits the gas to only flow out of the cooling tube 104. Therefore, when the telescopic airbag 96 is stretched, one of the mounting tubes 105 can draw gas from the external environment into the cooling tube 104, so that the gas is accumulated in the cooling tube 104. In addition, the cooling box 101 is filled with cooling liquid, and the cooling tube 104 is immersed in the cooling liquid. The cooling liquid can cool the gas accumulated in the cooling tube 104. Secondly, the top surface of the cooling box 101 is also installed with a semiconductor refrigeration sheet 103. When the semiconductor refrigeration sheet 103 is powered on, it can cool the cooling liquid in the cooling box 101 and keep the cooling liquid at a low temperature, thereby ensuring the cooling effect of the cooling liquid on the gas inside the cooling tube 104. The angle steel bending machine also includes a material unloading structure, which is arranged on the frame 1 and is located above the lifting structure. The material unloading structure includes: a servo motor 111, which is installed on the side of the frame 1; a material unloading wheel 112, which is fixed to the output end of the servo motor 111 and is located directly above the support plate 63. When unloading, the servo motor 111 runs and drives the material unloading wheel 112 to rotate. When the material unloading wheel 112 rotates, the angle steel can be moved under the action of friction, so that the angle steel falls into the inclined guide hopper 3, thereby realizing automatic unloading of the angle steel. One end of the guide hopper 3 is closed, and the angle steel will be temporarily accumulated in the guide hopper 3, and no manual unloading is required.

[0021] The specific working principle of the present invention is as follows: When the angle steel bending machine proposed by the present invention is in use, the staff places the heated angle steel between the two limit plates 55, and makes the two ends of the angle steel contact the corner positions of the two limit plates 55 respectively. Then, the hydraulic cylinder 2 is started and drives the bending head to move. When the bending head moves, it can push the angle steel. Under the cooperation of the two limit wheels on the frame 1, the middle position of the angle steel can be squeezed by the bending head and the bending is completed. In this process, the bending head can drive the driving rod 94 to move, and when the driving rod 94 moves, it drives the slide plate 93 to move. When the slide plate 93 moves, it can stretch the telescopic airbag 96. When the telescopic airbag 96 is stretched, it can perform a pumping action. For the cooling structure, the two one-way valves 106 installed on the two mounting pipes 105 have opposite flow limiting directions. Specifically, , one of the one-way valves 106 restricts the gas to only enter the interior of the cooling tube 104, and the other one-way valve 106 restricts the gas to only flow out of the cooling tube 104. Therefore, when the telescopic airbag 96 is stretched, one of the mounting tubes 105 can draw the gas in the external environment into the interior of the cooling tube 104, so that the gas accumulates in the cooling tube 104. In addition, coolant is accumulated in the cooling box 101, and the cooling tube 104 is immersed in the coolant. The coolant can cool down the gas accumulated in the cooling tube 104. Secondly, a semiconductor refrigeration sheet 103 is also installed on the top surface of the cooling box 101. When the semiconductor refrigeration sheet 103 is powered on, it can cool down the coolant in the cooling box 101, keep the coolant at a low temperature, thereby ensuring the cooling effect of the coolant on the gas inside the cooling tube 104. After the bending of the angle steel is completed, the hydraulic cylinder 2 drives the bending head to reset. When the bending head is reset, the driving rod 94 also drives the slide plate 93 to reset, so that the slide plate 93 squeezes the telescopic airbag 96. When the telescopic airbag 96 is squeezed, it can perform exhaust action and press out the low-temperature gas accumulated in the cooling pipe 104. In this process, the gas accumulated in the cooling pipe 104 will be pressed out through another mounting pipe 105 and enter the interior of the injection pipe 72. In the initial state, the second injection ports 75 on the rotating sleeve 74 and the first injection ports 73 on the injection pipe 72 are in a mutually misaligned state. At this time, the rotating sleeve 74 can block the first injection ports 73, and the gas in the injection pipe 72 cannot be ejected through the first injection ports 73. Therefore, when the low-temperature gas enters the interior of the injection pipe 72, it cannot be ejected through the first injection ports 73, so that the air pressure inside the injection pipe 72 increases. During the bending process, when the bending head pushes the angle steel to move, the angle steel can contact the push block 45 and push the push block 45 to move. When the push block 45 moves, it can drive the inner rod 43 to move, so that the inner rod 43 is retracted into the outer cylinder 42 and the first spring 44 is compressed. After the bending is completed, the bending head is reset under the action of the hydraulic cylinder 2. Without the extrusion of the bending head, the inner rod 43 will also be reset under the elastic force of the first spring 44, and drive the push block 45 to push the bent angle steel, so that the angle steel is also reset. When the bending head is completely reset, the push block 45 can just push the angle steel onto the supporting plate 63. The design of the reset structure realizes the automatic reset of the angle steel. Further, the servo cylinder 62 operates and drives the supporting plate 63 to move upward. When the supporting plate 63 moves upward, it can drive the angle steel thereon to move upward until the angle steel moves to a state of contact with the unloading wheel 112. In this case, the angle steel is just located opposite to the jet pipe 72. In addition, when the supporting plate 63 moves upward, it can also drive the rack 82 to move upward through the connecting rod 81. When the rack 82 moves upward, it can mesh with the gear 83 and drive the gear 83 to rotate. When the gear 83 rotates, it can drive the rotating sleeve 74 to rotate. When the rack 82 is separated from the gear 83, the second jet ports 75 on the rotating sleeve 74 and the first jet ports 73 on the jet pipe 72 are aligned with each other. At this time, the low-temperature gas accumulated in the jet pipe 72 will be ejected through the overlapping second jet ports 75 and the first jet ports 73, and sprayed toward the angle steel on the supporting plate 63. The low-temperature gas can cool the high-temperature angle steel to prevent the high-temperature angle steel from scalding the staff. In addition, the jet action can also improve the cooling efficiency of the high-temperature angle steel. The angle steel bending equipment also provides an automatic unloading function. When unloading, the servo motor 111 runs and drives the unloading wheel 112 to rotate. When the unloading wheel 112 rotates, the angle steel can be moved under the action of friction, so that the angle steel falls into the inclined guide hopper 3, realizing automatic unloading of the angle steel. One end of the guide hopper 3 is closed, and the angle steel will be temporarily accumulated in the guide hopper 3, without manual unloading. As for the adjustment structure, the staff can also adjust the positions of the two limit plates 55 according to the size of the angle steel, so that the two ends of the angle steel can contact the corner positions of the two limit plates 55. Specifically, the staff rotates the adjusting screw 52, ​​and under the limiting action of the guide rod 53, the adjusting screw 52 can drive the adjusting plate 54 to move when it rotates, and the adjusting plate 54 can drive the limit plate 55 to move when it moves, so that the position of the limit plate 55 can be quickly adjusted. In addition, scale lines can be set on the guide rod 53 to facilitate the staff to accurately adjust the position of the limit plate 55.
