Abstract
Description
Technical Field
[0001] This invention relates to the field of welding equipment technology, and in particular to a clamping assembly device for steel structure production. Background Technology
[0002] I-beam steel structures are widely used in construction, bridges, and large machinery manufacturing due to their excellent load-bearing capacity and structural stability. During the production of I-beam steel structures, the welding quality of the web and flanges directly affects the overall performance and service life of the structure. Existing equipment uses limited preheating and temperature control methods, resulting in poor temperature uniformity. This leads to large temperature gradients and concentrated thermal stress during welding, easily causing welding deformation and cracks. Furthermore, during the welding of I-beams, the fillet welds (usually double-sided continuous fillet welds) between the flanges and web are located outside the neutral axis of the cross-section, causing significant outward bending (angular deformation) of the flanges towards the weld side. This is especially problematic when welding one side first and then the other; the deformation from the first weld is "frozen," and the shrinkage of the second weld cannot completely offset it, leading to cumulative deformation and making the welding deformation problem particularly prominent.

[0038] The supporting element 62 includes an inclined vertical seat 621, a supporting cylinder 622, a supporting rotating frame 623, and a supporting mounting vertical plate 624. The bottom of the inclined vertical seat 621 is installed at the middle of one end of the jig frame 20. An L-shaped plate 625 is inclinedly provided on the inclined vertical seat 621. The supporting cylinder 622 is rotatably installed on the inner side of the L-shaped plate 625. The bottom of the supporting rotating frame 623 is rotatably installed on the top of the L-shaped plate 625, and the top of the inner side of the supporting rotating frame 623 is rotatably connected to the output shaft of the supporting cylinder 622.

A nozzle mounting seat 627 protrudes from the inner end of the bottom of the outer side of the supporting rotating frame 623. A supporting uniform temperature nozzle 628 is inclined downward from the nozzle mounting seat 627. The outer side of the top of the supporting mounting vertical plate 624 is installed on the bottom of the supporting vertical plate mounting block 626.
[0039] A sliding hole 629 is recessed in the middle of the side wall of the support mounting plate 624. A support sliding shaft 631 is slidably arranged in the support sliding hole 629. An inclined elastic perforated plate 632 is rotatably arranged on the outside of the support sliding shaft 631. An elastic arc plate 633 is arranged at the bottom of the inclined elastic perforated plate 632. An elastic air guide vertical perforated plate 634 is arranged at the top of the inclined elastic perforated plate 632. A return spring 635 is arranged between the inclined elastic perforated plate 632 and the support mounting plate 624.
[0040] For example, in one embodiment: a universal joint is provided on the inner side of the inclined elastic perforated plate 632, and the sliding shaft 631 is rotatably mounted in the universal joint. The temperature equalization nozzle 628, the end temperature equalization nozzle 45, and the temperature equalization nozzle 34 are all connected to an external temperature equalization air pump through pipes. The support mounting plate 624 and the inclined elastic perforated plate 632 are both made of thermally conductive material, and their inner sides are each provided with multiple heat dissipation grooves spaced along the length direction.
[0041] For example, in one embodiment: when welding of the I-shaped steel structure is required, the lower flange of the I-shaped steel structure is placed on the lateral moving seats 612 of the flange of the two supporting components 60 at both ends. Then, the bottom of the vertically set web is placed in the middle of the top surface of the lower flange, and the end positioning cylinders 42 of the two end clamping components 40 are activated simultaneously, thereby driving the rotating mounting plate 43 to rotate and move downward, so that the two inclined positioning frames 44 and the top corner pads 46 move together until the inner end of the top corner pads 46 abuts against the top of both ends of the web. When the inclined positioning frames 44 rotate downward, the elastic corner frame 441 will expand and deform outward, and the positioning roller 442 will abut against the corner of the top of the side wall of the web, thus vertically clamping the web. Simultaneously, the intermediate limiting cylinder 32 will start the intermediate temperature equalization rotor 33 to rotate and move downward, so that the outer side of the intermediate temperature equalization rotor 33 abuts against the middle of the top surface of the web plate, and the two temperature equalization nozzles 34 are respectively located on both sides of the web plate. Then, the wing plate lateral adjustment cylinder 614 is activated to adjust the position of the centering clamping seat 615, thereby pushing the lower wing plate on the wing plate lateral moving seat 612 to move accordingly, and adjusting the lower wing plate laterally to ensure that the web plate is in the "center" position. Then, the external isothermal air pump is activated to deliver isothermal airflow. The isothermal airflow is sprayed from the isothermal nozzle 628, the end isothermal nozzle 45, and the isothermal nozzle 34 to preheat the middle part of the web plate and the lower flange plate. Then, the external welding equipment is activated to weld the outer side of the joint between the web plate and the lower flange plate. At the same time, the isothermal cylinder 622 is activated, which drives the isothermal rotating frame 623 to rotate and move to one side of the web plate, thereby causing the isothermal mounting vertical plate 624 and the inclined elastic perforated plate 632 to follow. The movement is due to the rotatable installation of the outer side of the abutment slide 631 in the universal joint. When the outer side of the bottom of the inclined elastic perforated plate 632 first contacts the inner side of the web, the inclined elastic perforated plate 632 rotates and continues to move with the abutment rotating frame 623 until the elastic arc plate 633 abuts against the inner side of the junction of the web and the lower wing plate, and an obtuse-angled triangular gap space is formed between the inner side of the abutment mounting vertical plate 624, the inner side of the inclined elastic perforated plate 632 and the inner side of the web, thus supporting the web.
[0042] Simultaneously, when welding begins, the two monitoring cameras 47 will monitor the deformation offset of the web at the welding point. When the flange angle deformation is ≥1° during welding, the holding cylinder 622 will be activated again, driving the holding rotating frame 623 to continue moving, driving the holding mounting plate 624 and the inclined elastic perforated plate 632 to continue moving, causing the gap space to compress and deform, so that the inner side of the holding mounting plate 624 and the inner side of the inclined elastic perforated plate 632 abuts against the inner side of the web, applying outward stress to the web. At the same time, the external uniform temperature air pump will also increase the output of the uniform temperature airflow. Furthermore, since the inner side of the holding mounting plate 624 and the inner side of the inclined elastic perforated plate 632 abuts against the inner side of the web, the heat dissipation area is increased, heat is quickly conducted away, and the range of the heat-affected zone is reduced, achieving the purpose of real-time monitoring of distortion and fine-tuning correction.
[0043] For example, in one embodiment: when the welding of the outer side of the junction between the lower wing plate and the web plate is completed, the lower wing plate and web plate are removed and reversed. Then, the upper wing plate is lowered, and the moving motor on the fixed transverse cylinder 54 and the lifting transverse slide bar 56 is activated. The upper wing plate is clamped and centered using the top inner arc plate 561 and the top outer arc plate 541. Welding is then started to weld the inner side of the junction between the lower wing plate and the web plate and the junction between the upper wing plate and the web plate. During the welding process, two monitoring cameras 47 will monitor the process in real time.
