Description

Technical Field

[0001] The invention belongs to the technical field of steel structure production, and particularly relates to an integrated control device for assembling, welding and rectifying an H-shaped steel structure. Background Art

[0002] The H-beam welding and straightening machine is a special equipment for H-beam production. It combines the traditional assembly, welding and straightening into one, and mainly serves the prefabricated buildings, steel structure workshops, light steel villas, bridges, shipbuilding, subways, high-speed railways, drilling platforms, gas furnaces, weighbridges and other industries.

[0003] In the current H-beam component submerged arc welding production line, the semi-automatic welding correction mode is generally adopted. This process not only requires manual real-time position judgment and timely adjustment, but also lacks practical functions such as preheating and welding wire remaining monitoring. At the same time, the welding and correction machine disclosed by the invention patent with the authorization announcement number CN217344438U is a semi-automatic equipment, but it has obvious shortcomings in dealing with the side bending problem of the wing plate.

[0004] It can be seen that the existing welding and straightening machines have many defects: First, there is a missing link in the deformation detection of T-shaped / H-shaped steel after welding, and the deformation detection after correction relies too much on experience judgment and lacks quantitative standards, making it difficult to ensure the consistency and stability of product quality and unable to meet high-precision production needs.

[0005] Secondly, when the working environment temperature is low, the welding process is easily affected by the low temperature, which greatly reduces the welding effect and causes problems such as poor weld formation and reduced weld joint strength, which seriously affects the overall quality and structural performance of the product and increases the defective rate and rework costs.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] In the current technical field, the conventional H-shaped steel structure is formed by welding two flanges 104 and a web 113. In contrast, the T-shaped steel 103 lacks a flange 104.

[0032] The present embodiment discloses an integrated control device for welding and straightening an H-shaped steel structure, which is a special device capable of welding and straightening H-shaped steel and T-shaped steel.

[0033] like Figures 1 to 9 As shown, the H-shaped steel structure assembly welding and straightening integrated control device includes a frame and a feeding mechanism, a positioning mechanism, a preheating mechanism 114, a welding mechanism, a straightening mechanism 106, a weighing mechanism 116 and a processor installed on the frame.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, specifically, the rack serves as the basic support of the entire device and provides a stable installation position for each mechanism. The rack includes a base 111 and a platform 115. The platform 115 is erected on the base 111 and fixed thereto. A rectangular mounting seat is fixedly installed on both sides of the top of the base 111. Columns are fixed at both ends of the top of each mounting seat, and the platform 115 is fixed on the top of the column. A cantilever box 105 is fixed on one side of the platform 115. The cantilever box 105 is electrically connected to the processor, and commands are issued through the cantilever box 105 to control the operation of the entire device. Generally, the cantilever box 105 is installed on the left side of the platform 115. Similarly, a ladder 109 is fixedly connected to the left side of the platform 115. The ladder 109 is fixedly connected to the ground, and the staff climbs the ladder 109 to the platform 115.

[0035] In this embodiment, the feeding mechanism is fixedly mounted on the base 111, and a roller line is usually selected. The roller line belongs to conventional prior art and will not be described in detail here. The function of the roller line is to convey the steel forward and provide basic support for the welding work of the steel.

[0036] Continue as Figure 1 , Figure 2 and Figure 3 The positioning mechanism includes a flange centering mechanism 110, a web centering mechanism 112 and a pressing wheel mechanism. The flange centering mechanism 110 and the web centering mechanism 112 are installed on the side of the mounting seat at the top of the base 111, and the flange centering mechanism 110 and the web centering mechanism 112 clamp and position the flange 104 and the web 113 respectively. The pressing wheel mechanism is installed on the platform 115, and is used to press the top of the steel section.

[0037] like Figure 1 and Figure 4 As shown, in this embodiment, the number of the web centering mechanisms 112 is set to four, which are installed in groups of two on the mounting seat at the top of the base 111. One of the web centering mechanisms 112 is now described in detail, which includes a web servo motor 1121, a web reducer 1122, a flange 1123, a screw assembly 1124 and a web centering pressure wheel 1125. Specifically, the web servo motor 1121 is closely connected to the web reducer 1122, and the end face of the web reducer 1122 is firmly fixed with the flange 1123; at the same time, the end face of the outer shell of the screw assembly 1124 is also installed with a flange 1123, and these two flanges 1123 are precisely fixed to the mounting seat at the top of the base 111 by bolts, thereby ensuring the stability and firmness of the entire mechanism. In terms of power transmission, the web servo motor 1121 is connected to the screw assembly 1124 by means of the web reducer 1122, providing stable and precise power support for subsequent actions.

[0038] The number of web centering rollers 1125 is determined to be three. These three rollers are cleverly divided into two groups and rotatably mounted on the support plate, which is fixedly connected to the screw assembly 1124 to form an organic whole. During the steel transportation process, the four web centering mechanisms 112 are divided into two groups to center and position the steel. The web servo motor 1121 is started to drive the screw assembly 1124 to perform telescopic movement, thereby driving the web centering rollers 1125 to achieve forward and backward telescopic movement. Through this precise mechanical movement, the web 113 is effectively pressed and centered, so that the web 113 is in a stable operating state.

[0039] like Figure 1 and Figure 5 As shown, in this embodiment, the number of the wing plate centering mechanism 110 is set to two. For any wing plate centering mechanism 110, it includes two wing plate pressure wheels 1101, a pressure wheel seat, a T-type screw rod 1102, a wing plate servo motor 1103 and a wing plate reducer 1104. The two wing plate pressure wheels 1101 are both installed on the corresponding pressure wheel seat, the pressure wheel seat of the wing plate pressure wheel 1101 is located at both ends of the T-type screw rod 1102 and is threadedly connected thereto, and the two ends of the T-type screw rod 1102 are rotatably arranged on the centering mechanism seat, and the servo motor 1103 is tightly fixedly connected to the reducer 1104 and then installed on the centering mechanism seat, and the two ends of the centering mechanism seat are respectively fixedly connected to the mounting seat at the top of the base 111, and the output end of the wing plate reducer 1104 is connected to the T-type screw rod 1102. The wing plate centering mechanism 110 drives the T-type screw rod 1102 to rotate forward and reversely through the wing plate servo motor 1103, and then the wing plate pressure wheel 1101 moves to the middle or outside. When the wing plate pressure wheel 1101 moves to the middle, the wing plate 104 is clamped and centered.

[0040] In a possible embodiment, the two wing plate centering mechanisms 110 are located between the two sets of web plate centering mechanisms 112 . The two wing plate centering mechanisms 110 can keep the wing plate 104 in a stable operating state.

[0041] like Figure 2 and Figure 6 As shown, in this embodiment, the pressing wheel mechanism includes a main pressing wheel assembly 101 and a hydraulic pressing cylinder 121. The hydraulic pressing cylinder 121 is fixed on the top of the platform 115. The main pressing wheel assembly 101 is located below the platform 115. The main pressing wheel assembly 101 is connected to the telescopic rod of the hydraulic pressing cylinder 121. The main pressing wheel assembly 101 is used to press the top of the steel section.

[0042] In order to ensure the stable downward pressure of the pressure wheel mechanism on the steel section, the main pressure wheel assembly 101 includes an adjustment assembly 1011, a top pressure wheel 1012, a connecting rod 1013 and a pressure beam 1014. Specifically, the top pressure wheel 1012 is fixed to the bottom of the pressure beam 1014, the two ends of the connecting rod 1013 are respectively fixed to the hydraulic downward pressure cylinder 121 and the pressure beam 1014, and the adjustment assembly 1011 is two groups respectively fixed to the two ends of the pressure beam 1014. Each adjustment assembly 1011 is composed of two seat plates and two rollers, the two seat plates are fixed on both sides of the end of the pressure beam 1014, and the two rollers are located between the two seat plates and are rotatably connected to the seat plates. A limiting groove is formed on the roller, and a guide rail adapted to the limiting groove is installed on the two columns at the top of the base 111. When the hydraulic pressing cylinder 121 drives the main pressing wheel assembly 101 to move, the roller rolls along the guide rail, thereby ensuring the stability of the movement of the main pressing wheel assembly 101 and allowing the top pressing wheel 1012 to stably press on the top of the steel section.

[0043] like Figure 1 and Figure 7 In this embodiment, two preheating mechanisms 114 are provided, and the preheating mechanisms 114 are used to preheat the steel sections after positioning. Each preheating mechanism 114 includes a medium frequency heating device and a preheating control box 108 electrically connected to the medium frequency heating device. Among them, a heating device seat plate is fixed on two mounting plates with web centering pressure wheels 1125 adjacent to the mounting seat, and a cylinder is fixed on the heating device seat plate. The piston rod of the cylinder is fixed to the medium frequency heating device, and a contact wheel for contacting the wing plate 104 is installed at the bottom of the medium frequency heating device to ensure the distance between the medium frequency heating device and the wing plate 104. In actual use, while the web centering mechanism 112 centers the web 113, it drives the medium frequency heating device to move, and the cylinder drives the medium frequency heating device to move downward until the contact wheel contacts the wing plate 104, and the medium frequency heating device reaches the heating position.

[0044] The medium frequency heating device is inductively heated by an induction coil. The medium frequency heating device is an existing conventional technology and will not be elaborated on in detail here. Each medium frequency heating device is connected to a preheating control box 108, which is placed on the ground on one side of the base 111. The preheating control box 108 is electrically connected to the medium frequency heating device, and the preheating control box 108 is electrically connected to the processor.

[0045] In addition, a cold water tank 119 is provided on the ground at one side of the base 111 , and the cold water tank 119 is used to cool down the two intermediate frequency heating devices and protect them.

[0046] like Figure 2 and Figure 8As shown, there are two welding mechanisms, which are used to weld the preheated steel sections. Each welding mechanism includes a welding gun mechanical arm 120, a submerged arc welding machine 107, a flux barrel 118, a welding wire reel 117 and an exhaust fan 102.

[0047] In this embodiment, the welding gun robot arm 120 includes a Z-axis module 1201, a tank chain 1202, an X-axis module 1203, a welding servo motor 1204, a welding reducer 1205, a flux discharge pipe 1206, a welding gun 1207 and a flux recovery nozzle 1208. Specifically, the Z-axis module 1201 is fixed on the mounting frame at the top of the base 111, and the X-axis module 1203 is installed on the Z-axis module 1201. Both adopt an electric cylinder structure design and have good stability and precision control capabilities. The tank chain 1202 is interconnected with the X-axis module 1203 and the Z-axis module 1201, ensuring the orderly arrangement and stable transmission of various cables during the operation of the equipment, effectively avoiding problems such as cable entanglement, and providing reliable guarantee for the stable operation of the equipment. After the welding servo motor 1204 is tightly fixedly connected with the welding reducer 1205, it is installed on the X-axis module 1203. The output shaft of the welding reducer 1205 is flexibly connected to the rotating seat, and the flux discharge pipe 1206, welding gun 1207 and flux recovery nozzle 1208 are all installed on the rotating seat.

[0048] In this embodiment, the flux barrel 118 is fixed at the front end of the platform 115, and a flux conveyor corresponding to the flux barrel 118 is fixed on the column, which is connected to the flux discharge pipe 1206. The three cooperate with each other to evenly place the flux at the welding position of the wing plate 104.

[0049] The welding wire reel 117 is placed on the top of the platform 115, and the welding wire is wound on the welding wire reel 117. The welding wire on the welding wire reel 117 is fed into the welding gun 1207 through the welding wire feeder on the column, and the welding gun 1207 is connected to the submerged arc welding machine 107, and the submerged arc welding machine 107 is placed on the ground on one side of the base 111. The submerged arc welding machine 107 and the welding gun 1207 are both electrically connected to the processor and are used for welding the wing plate 104 and the web plate 113.

[0050] The exhaust fan 102 is fixed on the top of the platform 115, and the exhaust fan 102 is electrically connected to the processor. The exhaust fan 102 is connected to the flux recovery nozzle 1208 through a pipeline for recovering excess flux after welding.

[0051] In the actual operation of the equipment, the Z-axis module 1201 plays a key role. Its main function is to accurately control the height position of the welding gun 1207 in the vertical direction, so as to ensure that the welding depth and the molten pool state during the welding process meet the process requirements; the X-axis module 1203 is responsible for accurately adjusting the moving distance of the welding gun in the horizontal direction to ensure the accuracy of the welding position and the linear accuracy of the weld; the servo motor 1204 and the reducer 1205 work together to finely adjust the angle of the welding gun to adapt to the angle requirements of different welding parts and processes; and the welding gun robot arm 120, as an integral system, is mainly used for all-round and high-precision adjustment of the positions of the flux discharge pipe 1206, the welding gun 1207 and the flux recovery nozzle 1208 in the entire three-dimensional space through the organic coordination of various components, so as to meet the complex and diverse welding process requirements.

[0052] like Figure 2 and Fig. 9 As shown, the correction mechanism 106 is installed on the base 111 and is used to correct the welded steel section.

[0053] In a preferred embodiment, the correction mechanism 106 includes a correction servo motor 1061, a correction reducer 1062, a correction seat assembly 1063, a wing plate deformation detection assembly 1064 after correction, a power wheel 1065, a temperature sensor 1066, a support base 1067, a sealing plate 1068, a wing plate deformation detection assembly 1069 before correction and a correction wheel 10610.

[0054] The support base 1067 is installed on the base 111, and the support base 1067 passes through the roller line, and the two ends of the support base 1067 are located on both sides of the roller line. The two correction seat assemblies 1063 are respectively slidably installed on the two ends of the top of the support base 1067. The two correction seat assemblies 1063 are controlled by the servo mechanism to approach or move away from each other. The power wheel 1065 is rotatably installed in the middle of the support base 1067. The power wheel 1065 is driven by a motor, and the steel section can move on the power wheel 1065; The temperature sensor 1066 is fixedly installed on the correction seat assembly 1063, the wing plate deformation detection assembly 1069 before correction and the wing plate deformation detection assembly 1064 after correction are respectively installed on the front and rear sides of the support base 1067, and the wing plate deformation detection assembly 1069 before correction and the wing plate deformation detection assembly 1064 after correction can adjust their positions under the control of the servo motor module; the correction servo motor 1061 is fixedly connected to the correction reducer 1062 and installed on the top of the correction seat assembly 1063, and a screw rod and a sliding seat are installed in the correction seat assembly 1063, the screw rod is connected to the correction servo motor 1061, and the correction wheel 10610 is installed on the sliding seat. The correction wheel 10610 is in the shape of a truncated cone, and the correction servo motor 1061 drives the screw rod to rotate, thereby driving the correction wheel 10610 to move up and down.

[0055] The correction wheel 10610 can be adjusted up and down under the action of the correction servo motor 1061, the correction seat assembly 1063 can be servo-adjusted in size in the middle of left and right, the wing plate deformation detection assembly 1064 after correction and the wing plate deformation detection assembly 1069 before correction can adjust the left and right middle distance under the adjustment of the module, and thus the correction mechanism 106 can correct different types of profiles.

[0056] like Figure 1 As shown, in this embodiment, two weighing mechanisms 116 are provided, the weighing mechanisms 116 are fixed at the top edge of the platform 115, the welding wire reel 117 is placed on the top of the weighing mechanism 116, the weighing mechanism 116 is an electronic scale, and the weighing mechanism 116 is used to weigh the real-time weight of the welding wire. By adding the welding wire weighing function (and calculating the amount of one wire to ensure that the remaining amount can weld the whole wire), the remaining amount of the welding wire can be known in advance to alarm and ensure the welding of the whole wire.

[0057] In this embodiment, the processor is connected to the feeding mechanism, positioning mechanism, preheating mechanism 114, welding mechanism, correction mechanism 106 and weighing mechanism 116, and all-round control of the steel section welding work is achieved through precise control of each mechanism.

[0058] The implementation principle of this embodiment is: When the T-shaped steel 103 or H-shaped steel has completed the spot welding process, it will be transported to the designated position in front of the device through the roller line. At this time, the wing plate centering mechanism 110, the web plate centering mechanism 112 and the pressing wheel mechanism will be quickly started to accurately clamp the wing plate 104, clamp the web plate 113, and press down the steel, so as to achieve accurate positioning and location of the steel, ensuring the accuracy of subsequent processing.

[0059] At the same time, the preheating mechanism 114 begins to play its preheating function and preheats the part of the steel to be welded to optimize the welding quality. With the continuous transmission of the roller line, when the steel reaches the flux discharge pipe 1206, an appropriate amount of flux will be evenly placed on the welding part, providing good molten pool protection and filling conditions for the subsequent welding process. Next, the steel is conveyed to the welding gun 1207, where the welding gun performs high-quality welding operations according to the preset welding parameters and process path to ensure the strength and sealing of the weld. During the welding process, the flux recovery nozzle 1208 will work synchronously to recover excess flux in time to achieve the recycling of flux and keep the welding area tidy and clean.

[0060] After welding is completed, the steel section will continue to move to the wing panel deformation detection component 1069 before correction. This detection component will use advanced sensing technology and measurement algorithms to accurately detect the deformation of the wing panel 104 and record these data in detail. Subsequently, the control system will accurately control the correction mechanism 106 to move the corresponding distance based on the recorded deformation value, so as to ensure that the correction process can be targeted and achieve the best correction effect. After the correction treatment of the correction mechanism 106, the steel section will reach the wing panel deformation detection component 1064 after correction. This component will detect the deformation of the wing panel 104 again and record the actual deformation data after correction, so as to evaluate and trace the quality of the entire processing process and provide strong data support for subsequent process optimization.

[0061] During this process, the weighing mechanism 116 can accurately measure and collect data on the weight of the welding wire, and accurately calculate the approximate amount of welding wire required to weld a steel section. At the same time, by real-time monitoring of the weight change of the welding wire, the system can also clearly determine the level of the remaining welding wire after completing the welding of a steel section, so as to ensure that there is sufficient and appropriate supply of welding wire for each subsequent welding of the steel section, thereby effectively avoiding welding quality problems or material waste caused by insufficient or excessive welding wire, and greatly improving the stability, reliability and cost-effectiveness of the welding process.
