Description

Technical Field

[0001] The invention relates to the technical field of welding devices, and in particular provides a clamping type assembling device for steel structure production. Background Art

[0002] I-shaped steel structures are widely used in fields such as construction, bridges, and large-scale machinery manufacturing due to their excellent load-bearing capacity and structural stability. During the production process of I-shaped steel structures, the welding quality of the web and flange directly affects the overall performance and service life of the structure. Existing equipment has a single preheating and temperature control method, and the temperature uniformity is poor. This leads to large temperature gradients and concentrated thermal stress during welding, which can easily cause welding deformation and cracks. In addition, when welding I-shaped steel, the fillet weld between the welded flange and the web (usually a double-sided continuous fillet weld) is located outside the neutral axis of the cross-section. As a result, the flange will undergo significant outward bending (angular deformation) toward the weld side during welding. In particular, when welding one side first and then the other side, the deformation caused by the weld on the first side will be "frozen" and cannot be completely offset when the weld on the second side shrinks, resulting in cumulative deformation, which in turn makes the welding deformation problem particularly prominent.

[0036] 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 in the middle of one end of the jig frame 20. The inclined vertical seat 621 is inclinedly provided with an L-shaped plate 625. 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 inner top of the supporting rotating frame 623 is rotatably connected to the output shaft of the supporting cylinder 622. A supporting vertical plate mounting block 626 is protruded from the outer end of the outer bottom of the supporting rotating frame 623. A nozzle mounting seat 627 is protruded from the inner end of the outer bottom of the supporting rotating frame 623. The nozzle mounting seat 627 is inclined downwardly provided with a supporting temperature equalizing nozzle 628. The outer side of the top of the supporting mounting vertical plate 624 is installed at the bottom of the supporting vertical plate mounting block 626.

[0037] A supporting sliding hole 629 is recessed in the middle of the side wall of the supporting mounting vertical plate 624, a supporting sliding shaft 631 is slidingly arranged in the supporting sliding hole 629, an inclined elastic hole plate 632 is rotatably arranged on the outside of the supporting sliding shaft 631, an elastic arc plate 633 is arranged at the bottom of the inclined elastic hole plate 632, an elastic air-guiding vertical hole plate 634 is arranged at the top of the inclined elastic hole plate 632, and a return spring 635 is arranged between the inclined elastic hole plate 632 and the supporting mounting vertical plate 624.

[0038] For example, in one embodiment, a universal joint is installed inside the inclined elastic orifice plate 632, and the outer side of the supporting slide shaft 631 is rotatably mounted within the universal joint. The supporting temperature-averaging nozzle 628, the end temperature-averaging nozzle 45, and the temperature-averaging nozzle 34 are all connected to an external temperature-averaging air pump via pipes. Both the supporting mounting vertical plate 624 and the inclined elastic orifice plate 632 are made of thermally conductive material, and each has multiple heat dissipation grooves recessed along its length.

[0039] For example, in one embodiment: when it is necessary to weld an I-shaped steel structure, the lower wing plate of the I-shaped steel structure is placed on the wing plate transverse moving seats 612 of the two supporting assemblies 60 at the bottom ends respectively, and then the bottom of the vertically arranged web is placed in the middle of the top surface of the lower wing plate, and the end positioning cylinders 42 of the two end clamping assemblies 40 are started synchronously, thereby driving the rotating mounting plate 43 to rotate and move downward, thereby causing the two inclined positioning frames 44 and the top corner pads 46 to follow the movement until the inner ends of the top corner pads 46 are abutted against the tops of the two ends of the web, and when the inclined positioning frame 44 rotates and moves 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 web side wall, thereby vertically clamping the web. At the same time, the middle limiting cylinder 32 will start to drive the middle temperature equalizing rotor 33 to rotate downward, so that the outer side of the middle temperature equalizing rotor 33 is against the middle of the top surface of the web, and the two temperature equalizing nozzles 34 are respectively located on both sides of the web. Then the wing plate transverse adjustment cylinder 614 is started to adjust the position of the centering clamping seat 615, and then the lower wing plate on the wing plate transverse moving seat 612 is pushed to move, and the lower wing plate is adjusted laterally to ensure that the web is in the "center" position. Then, the external uniform temperature air pump is started to deliver the uniform temperature airflow, which is ejected from the supporting uniform temperature nozzle 628, the end uniform temperature nozzle 45 and the uniform temperature nozzle 34 to preheat the web and the middle of the lower wing plate. Then, the external welding equipment is started to weld the outer side of the joint between the web and the lower wing plate. At the same time, the supporting cylinder 622 is started to drive the supporting rotating frame 623 to rotate and move to one side of the web, so that the supporting mounting vertical plate 624 and the inclined elastic hole plate 632 follow Movement, since the outer side of the supporting sliding shaft 631 is rotatably installed in the universal joint, when the outer side of the bottom of the inclined elastic hole plate 632 first contacts the inner side of the web, the inclined elastic hole plate 632 rotates and continues to move with the supporting rotating frame 623 until the elastic arc plate 633 is supported on the inner side of the junction of the web and the lower wing plate, and an obtuse triangle gap space is formed between the inner side of the supporting installation vertical plate 624, the inner side of the inclined elastic hole plate 632 and the inner side of the web to support the web.

[0040] At the same time, when welding starts, the two monitoring cameras 47 will respectively monitor the deformation offset of the web at the welding point. When the flange angle deformation is ≥1° during welding, the supporting cylinder 622 will start again, driving the supporting rotating frame 623 to continue to move, driving the supporting mounting vertical plate 624 and the inclined elastic hole plate 632 to continue to move, so that the gap space is compressed and deformed, so that the inner side of the supporting mounting vertical plate 624 and the inner side of the inclined elastic hole plate 632 are pressed against the inner side of the web, applying outward stress to the web, and at the same time, the external uniform temperature air outlet pump will also increase the outlet volume of the uniform temperature airflow, and because the inner side of the supporting mounting vertical plate 624 and the inner side of the inclined elastic hole plate 632 are pressed against the inner side of the web, the heat dissipation area is increased, the heat is quickly conducted away, and the range of the heat affected zone is reduced, so as to achieve the purpose of real-time monitoring of distortion and fine-tuning correction.

[0041] For example, in one embodiment, when the welding of the outer side of the lower wing plate and the web plate is completed, the lower wing plate and the web plate are removed and reversed. Then, the upper wing plate is lowered, and the fixed transverse cylinder 54 and the moving motor on the lifting transverse slide 56 are activated. The top inner arc piece 561 and the top outer arc piece 541 are used to clamp and center the upper wing plate. Then, welding is started again to weld the inner side of the lower wing plate and the web plate, and the upper wing plate and the web plate. The two monitoring cameras 47 monitor the welding process in real time.
