Description

Technical Field

[0001] This invention relates to the field of assembly machine technology, and specifically to a tilting H-beam assembly and welding machine. Background Technology

[0002] H-beams have an "H"-shaped cross-section, with all parts arranged at right angles. They are widely used in various steel structure projects such as buildings, bridges, factories, and wind turbine towers. As the core process in the production of H-beams, assembly welding directly determines the production quality and overall benefits of H-beams. Therefore, the development of efficient, convenient, and automated H-beam assembly welding equipment has become an urgent need for the industry.

[0003] Currently, existing H-beam assembly and welding processes generally adopt a segmented operation mode, with corresponding assembly and welding equipment mostly distributed. Their structural principles and operational processes have significant limitations, specifically as follows: In existing technologies, the assembly and welding of H-beams typically requires at least two assembly and welding machines working in coordination, along with independent material handling, turning, and conveying equipment to complete the entire H-beam processing flow. Specifically, the first assembly machine positions and assembles the web plate and a flange plate, followed by spot welding and full welding at the connection point to form a T-shaped section. Semi-finished steel sections: Using a manually operated crane or specialized handling equipment, the semi-finished T-shaped steel sections are transported from the first assembly machine to an independent flipping device, where the T-shaped steel is flipped 180° to ensure that the unwelded web side faces upwards for docking with another flange plate. After flipping, the semi-finished T-shaped steel section is transferred to the second assembly machine via handling equipment. The second assembly machine completes the positioning, alignment, and welding of the T-shaped steel section with the other flange plate, ultimately forming a complete finished H-shaped steel section. After the finished product is welded, it needs to be transferred to the unloading area via additional conveying equipment to complete the entire processing flow.

[0004] The existing structural layout and operation mode have the following technical problems: the flipping mechanism is separate from the assembly and welding mechanism, requiring additional conveying and flipping equipment. The connection between each process requires manual labor or additional equipment, which cannot achieve continuous operation and reduces the overall production efficiency. The web and flange plates of H-beams are mostly large steel plates. During multiple handling and transfer processes, the surface of the workpiece is prone to scratches, bumps, and even deformation. In particular, the welded T-beam semi-finished products are prone to weld cracking and deformation due to the incomplete curing of the welds after welding. This increases the product defect rate and production costs. Summary of the Invention

[0005] Therefore, the present invention provides a flip-type H-beam assembly welding machine, which effectively solves the technical problems of the prior art, such as the inability to achieve continuous operation and the cracking and deformation of the weld due to handling and collision.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1-5 As shown, this invention provides a tilting H-beam assembly and welding machine, which integrates multiple functions such as feeding, assembly, welding, transportation, tilting, and lifting. Through the coordinated operation of various structures, it completes the assembly and welding processes of the web plate 2 and the flange plate 1, ultimately forming an H-beam. The specific structure and working principle of this equipment are described in detail below: The feeding device 3 can transport the flange plate 1 to be processed to the designated station of the assembly device 4 to prepare for the subsequent assembly process. On the other hand, it can transport the finished H-beams that have completed all assembly and welding processes from the assembly device 4 to the unloading area to realize the closed-loop flow of materials and avoid the inefficiency and workpiece damage caused by manual transfer. The feeding device 3 includes a feeding rack 31 and several feeding rollers 32 installed on the feeding rack 31. The feeding rollers 32 rotate to transport the materials forward.

[0022] The assembly device 4 is located downstream of the feeding device 3. The assembly device 4 performs position correction and alignment on the flange plate 1 and the web plate 2, adapting to two assembly scenarios: one is for the flange plate 1 and web plate 2 alone in the initial state, correcting and aligning the relative positions of the flange plate 1 and web plate 2; the other is for the formed T-shaped steel piece and another flange plate 1 to be assembled, correcting the relative positions of the flange plate 1 and the web plate 2 in the T-shaped steel piece to ensure that the two are aligned and meet the assembly requirements of the H-shaped steel. Welding assembly 5 is mounted on assembly device 4, and its welding torch can be aimed at the joint between flange plate 1 and web plate 2. Welding assembly 5 is suitable for two welding scenarios: one is to weld flange plate 1 and web plate 2 after assembly and alignment to form T-shaped steel parts; the other is to weld the joint between flange plate 1 and web plate 2 of T-shaped steel parts after assembly and alignment to finally form H-shaped steel. The transport device 6 is located at the downstream end of the assembly device 4. The transport device 6 is used for the transfer and transport of T-shaped steel parts. After the T-shaped steel parts are welded on the assembly device 4, the transport device 6 works in coordination with the assembly device 4 to move the T-shaped steel parts to the downstream end of the equipment in a synchronous manner until the T-shaped steel parts are completely above the transport device 6 and positioned within the clamping range of the subsequent flipping device 7, in preparation for the flipping process. The flipping device 7 is symmetrically arranged at both ends of the transport device 6. The flipping device 7 can achieve a 180° flip of the T-shaped steel piece, ensuring that the position of the web plate 2 of the T-shaped steel piece after flipping is consistent with the subsequent assembly requirements. The lifting assembly 8 corresponds one-to-one with the tilting device 7 and is symmetrically arranged at both ends of the transport device 6. The lifting assembly 8 drives the tilting device 7 and the clamped T-shaped steel piece to move up and down: when a tilting operation is required, the lifting assembly 8 drives the tilting device 7 to rise, so that the T-shaped steel piece is removed from the surface of the transport device 6, avoiding interference with the transport device 6 during the tilting process; after the tilting is completed, the lifting assembly 8 drives the tilting device 7 and the tilted T-shaped steel piece to fall, which facilitates subsequent reverse transport.

[0023] After the flange plate 1 and the web plate 2 are assembled on the assembly device 4, the welding assembly 5 automatically welds the joint between them to form a T-shaped steel piece. Then, the assembly device 4 and the transport device 6 operate synchronously, transporting the T-shaped steel piece directly above the transport device 6. Simultaneously, the T-shaped steel piece is positioned and clamped onto the tilting device 7. Next, the lifting assembly 8 starts, driving the tilting device 7 and the clamped T-shaped steel piece upwards. After reaching the designated height, the tilting device 7 rotates the T-shaped steel piece 180°. After the rotation is complete, the lifting assembly... Component 8 drives the flipping device 7 and the flipped T-shaped steel piece to descend; then, the flipped T-shaped steel piece is transported back to the designated station of the assembly device 4; the assembly device 4 performs position correction and alignment on the other flange plate 1 that is reloaded and the flipped T-shaped steel piece, the welding component 5 is restarted, and the joint between the T-shaped steel piece and the flange plate 1 is welded to finally form the H-shaped steel; finally, the assembly device 4 drives the finished H-shaped steel to the upstream end, and the unloading operation is completed by the loading device 3, and the entire H-shaped steel assembly and welding process is completed in a closed loop.

[0024] This invention enables integrated and automated H-beam assembly and welding: the feeding device 3 completes bidirectional material transfer, the assembly device 4 achieves positioning and alignment of different workpieces, the welding assembly 5 completes staged welding, and the transport, flipping, and lifting assembly 8 collaboratively achieves the flipping and reverse conveying of T-beams. No additional flipping equipment is required; a single device can continuously complete all processes of "web plate 2 + flange plate 1 assembly and welding → T-beam flipping → T-beam and another flange plate 1 assembly and welding → finished product unloading". This simplifies the assembly and welding steps of H-beams, reduces equipment investment and floor space, and lowers the intensity of manual operation. At the same time, through the coordinated control of various devices, the overall production efficiency is improved.

[0025] In this invention, the assembly device 4 performs position correction and alignment on the flange plate 1 and the web plate 2. The specific structure of the assembly device 4 is as follows: like Figures 3-6 As shown, the assembly device 4 mainly consists of a first mounting base 41, a first gantry frame 42, a movable seat 43, a first alignment wheel 44, a second alignment wheel 45, and a first adjustment cylinder. Specifically, it includes a set of symmetrically arranged first mounting bases 41, on which the first gantry frame 42 is fixedly installed. Movable movable seats 43 are symmetrically arranged inside the first mounting bases 41. The first alignment wheel 44 and the second alignment wheel 45 are correspondingly installed on the movable seat 43. The first alignment wheel 44 is used to limit and align the flange 1, and the second alignment wheel 45 is used to limit and align the web 2.

[0026] The inner end of the movable seat 43 is equipped with a first adjusting cylinder. The movable seat 43 is fixedly connected to the drive end of the first adjusting cylinder. In the working state, the first alignment wheel 44 is tightly abutted against the side edge of the flange 1, and the second alignment wheel 45 is tightly abutted against the side wall of the web 2. Through the extension and retraction drive of the first adjusting cylinder, the movable seat 43 can be driven to move inward in the horizontal direction, thereby simultaneously driving the first alignment wheel 44 and the second alignment wheel 45 to move inward, so as to realize the clamping and positioning of the flange 1 and the web 2.

[0027] In the initial state, the distance between the two sets of first alignment wheels 44 that are directly opposite each other is greater than the width of the flange plate 1, and the distance between the two sets of second alignment wheels 45 that are directly opposite each other is greater than the thickness of the web plate 2, leaving enough space for loading. When the flange plate 1 is transported by the loading device 3 to the designated station of the assembly device 4, and the web plate 2 is placed vertically on the top surface of the flange plate 1 by the lifting structure (such as a hook or other lifting device), the first adjustment cylinder is activated, driving the movable seat 43 to move inward, which in turn drives the first alignment wheels 44 and the second alignment wheels 45 to move inward synchronously until they tightly clamp the flange plate 1 and the web plate 2, completing the initial position correction and alignment.

[0028] In practical applications, the flange plate 1 is fed by the feeding device 3, while the web plate 2 is hoisted to the top surface of the flange plate 1 by the hoisting structure and kept in an upright state. After the first alignment wheel 44 clamps the flange plate 1 and the second alignment wheel 45 clamps the web plate 2, the first alignment wheel 44 and the second alignment wheel 45 can rotate synchronously, driving the flange plate 1 and the web plate 2 to move forward or backward at the same time. In order to achieve stable rotation of the first alignment wheel 44 and the second alignment wheel 45, a drive motor is usually provided at the bottom of both the first alignment wheel 44 and the second alignment wheel 45.

[0029] Simply limiting and aligning the sides of the flange plate 1 and the web plate 2 is insufficient to meet the height alignment requirements during assembly. To further improve assembly accuracy, a first lifting cylinder 46 is fixedly installed on the first gantry frame 42. The driving end of the first lifting cylinder 46 is downward-facing and fixedly connected to a lifting plate 47. Guide wheels 48 are mounted on both sides of the lifting plate 47. Correspondingly, a guide rail 49 adapted to the guide wheel 48 is provided on the inner side of the first gantry frame 42. The guide wheel 48 is rotatably installed in the guide rail 49. A top pressure wheel 410 is fixedly installed at the bottom of the lifting plate 47. During operation, the top pressure wheel 410 can abut against the top of the web plate 2 or the top of the T-shaped steel piece to achieve height-direction positioning.

[0030] like Figure 4 , Figure 5 and Figure 6As shown, a second mounting base 411 is symmetrically arranged at the downstream end of the first mounting base 41. Several sets of symmetrically arranged third alignment wheels 412 and fourth alignment wheels 413 are arranged between the second mounting bases 411 for secondary positioning and alignment of the flange plate 1 and the web plate 2. A horizontally movable plate 414 is arranged between the second mounting bases 411. The third alignment wheels 412 and fourth alignment wheels 413 are fixedly installed on the movable plate 414. At the same time, a second adjustment cylinder is assembled between the second mounting bases 411. The movable plate 414 is fixedly connected to the drive end of the second adjustment cylinder. Through the extension and retraction drive of the second adjustment cylinder, the movable plate 414 and the third alignment wheels 412 and fourth alignment wheels 413 can be driven to move synchronously. In addition, several first bottom support wheels 415 are installed between the first mounting bases 41 and between the second mounting bases 411. The first bottom support wheels 415 are evenly arranged and provide stable support for the flange plate 1.

[0031] The third alignment wheel 412 has the same structure and function as the first alignment wheel 44, and it abuts tightly against the side edge of the flange 1 during operation; the fourth alignment wheel 413 has the same structure and function as the second alignment wheel 45, and it abuts tightly against the side wall of the web 2; after the second adjustment cylinder is started, it can drive the movable plate 414 to move inward in the horizontal direction, and then simultaneously drive the third alignment wheel 412 and the fourth alignment wheel 413 to move inward, so as to achieve double clamping and alignment of the flange 1 and the web 2 in conjunction with the first alignment wheel 44 and the second alignment wheel 45.

[0032] In the above structure, the third alignment wheel 412, the fourth alignment wheel 413 and the first bottom support wheel 415 are all connected to a drive motor. The drive motor provides power to drive the third alignment wheel 412, the fourth alignment wheel 413 and the first bottom support wheel 415 to rotate synchronously, thereby driving the flange plate 1 and the web plate 2 to move synchronously.

[0033] To further align the web 2 and flange 1 along their length and eliminate positional deviations in the length direction, such as... Figure 3 and Figure 7 As shown, a mounting plate 416 is fixedly disposed between the first mounting bases 41. A rotating shaft 417 is fixedly mounted on the mounting plate 416. A limit bolt 418 is rotatably disposed on the rotating shaft 417. The limit bolt 418 is arranged vertically. During operation, the ends of the flange plate 1 and the web plate 2 can abut against the limit bolt 418 to achieve positioning and alignment of the two in the length direction.

[0034] The specific process of alignment in the length direction is as follows: under the synchronous rotation drive of the first alignment wheel 44, the second alignment wheel 45, the third alignment wheel 412, the fourth alignment wheel 413 and the first bottom support wheel 415, the flange plate 1 and the web plate 2 move forward slowly until the ends of the two abut against the limit bolt 418. At this time, the flange plate 1 and the web plate 2 are aligned in the length direction.

[0035] During the alignment process, the flange 1 / web 2 moves toward the limiting bolt 418, rotating the limiting bolt 418 to adjust it to an upright position; after alignment, the limiting bolt 418 is laid down to a horizontal position to prevent obstruction of transported materials, and then transport is started.

[0036] To adapt to the welding operation of welding assembly 5, and to ensure that the welding torch tip can be aligned with the junction of the web plate 2 and the flange plate 1, such as... Figure 5 As shown, side mounting brackets 419 are symmetrically arranged between the second mounting bases 411. The side mounting brackets 419 have through holes 420 adapted to the welding assembly 5. The head of the welding assembly 5 can pass smoothly through the through holes 420 and be aligned with the junction of the web plate 2 and the flange plate 1, so as to avoid the side mounting brackets 419 interfering with the welding operation.

[0037] In this embodiment of the invention, the welding gun of the welding assembly 5 is fixed in position. Initially, the welding gun is used to perform preliminary welding at multiple positions (positions directly opposite the welding gun) between the web plate 2 and the flange plate 1. After welding is completed, the flange plate 1 and the web plate 2 are fixedly connected to form a T-shaped steel piece. Then, continuous welding is achieved by moving the T-shaped steel piece.

[0038] In this invention, the specific alignment and assembly process of the individual flange plate 1 and web plate 2 is as follows: First, the flange plate 1 is transported by the feeding device 3 to the designated work position between the first mounting base 41 and the second mounting base 411, and is stably supported by the first bottom support wheel 415; then, the web plate 2 is placed vertically on the top surface of the flange plate 1 through the hoisting structure to complete the initial feeding; next, the first adjustment cylinder is activated, driving the movable seat 43 to move inward, driving the first alignment wheel 44 and the second alignment wheel 45 to move inward; at the same time, the second adjustment cylinder is activated, driving the movable plate 414 to move inward, driving the third alignment wheel 412 and the fourth alignment wheel 413 to move inward, until the first alignment wheel 44 and the third alignment wheel 412 cooperate to clamp the flange plate 1, and the second alignment wheel 45 and the fourth alignment wheel 413 cooperate to stably clamp the web plate 2, completing the side limit alignment of the flange plate 1 and the web plate 2; Afterwards, each drive motor starts, driving the first alignment wheel 44, the second alignment wheel 45, the third alignment wheel 412, the fourth alignment wheel 413 and the first bottom support wheel 415 to rotate synchronously, smoothly driving the flange plate 1 and the web plate 2 to move forward together until the ends of both abut against the limit bolt 418, completing the alignment in the length direction; after the alignment is completed, the first lifting cylinder 46 starts, driving the lifting plate 47 to drive the top pressure wheel 410 to move downward, pressing the web plate 2 tightly against the flange plate 1, realizing the height direction limit fixation, and completing all alignment processes; After the alignment is completed, the welding assembly 5 is started to weld the joint between the flange plate 1 and the web plate 2 to form a T-shaped steel piece. After the initial welding is completed, the top pressure wheel 410 is lifted and released under the drive of the lifting plate 47. Then, each alignment wheel and bottom support wheel continue to rotate, driving the T-shaped steel piece to move slowly downstream. During the movement, the welding assembly 5 continues to weld the joint between the flange plate 1 and the web plate 2 to ensure that the weld is continuous and uniform.

[0039] The alignment and assembly process of the T-shaped steel piece and another flange plate 1 is completely consistent with the alignment and assembly process of the flange plate 1 and web plate 2 mentioned above. Through the same clamping, alignment, and fixing process, the T-shaped steel piece and the flange plate 1 are connected.

[0040] The transport device 6 is mainly used for transporting and temporarily supporting the T-shaped steel components that are about to be flipped. The specific structure of the transport device 6 is as follows: like Figure 8 and Figure 9 As shown, the transport device 6 includes a third mounting base 61 symmetrically arranged at the downstream end of the second mounting base 411. Several second bottom support wheels 62 and several fifth alignment wheels 63 are evenly arranged between the third mounting bases 61. The second bottom support wheels 62 are used to support the bottom of the T-shaped steel piece to ensure the horizontal state of the T-shaped steel piece during transport. The fifth alignment wheels 63 are closely abutted against the outer edge of the flange plate 1 of the T-shaped steel piece to play a lateral limiting role and prevent the T-shaped steel piece from shifting laterally during transport.

[0041] The second bottom support wheel 62 and the fifth alignment wheel 63 are each connected to a drive motor. The drive motor provides power to drive the second bottom support wheel 62 and the fifth alignment wheel 63 to rotate synchronously, thereby driving the T-shaped steel piece to move forward smoothly. The specific conveying process is as follows: under the coordinated rotation of the first alignment wheel 44, the second alignment wheel 45, the third alignment wheel 412, the fourth alignment wheel 413 and the first bottom support wheel 415, the T-shaped steel piece gradually moves onto the second bottom support wheel 62. Then, under the support of the second bottom support wheel 62 and the limiting and driving action of the fifth alignment wheel 63, the T-shaped steel piece slowly moves towards the downstream end of the conveying device 6 until it is completely above the conveying device 6.

[0042] In this invention, the lifting component 8 can drive the tilting device 7 to rise and fall. The specific structure of the lifting component 8 is as follows: like Figure 8 , Figure 9 and Figure 10 As shown, the lifting assembly 8 includes a second gantry 81 symmetrically arranged at the upstream and downstream ends of the third mounting base 61. A vertical slide rail 82 is fixedly arranged on the inner side of the second gantry 81, and a lifting frame 83 is slidably assembled between the vertical slide rails 82. The lifting frame 83 can slide smoothly up and down along the vertical slide rails 82.

[0043] A second lifting cylinder is fixedly installed on the second gantry frame 81. The end of the lifting frame 83 is fixedly connected to the drive end of the second lifting cylinder. During operation, the lifting frame 83 can be driven to move up and down along the vertical slide rail 82 by the extension and retraction drive of the second lifting cylinder, thereby synchronously driving the tilting device 7 installed on the lifting frame 83 to move up and down together, so as to realize the lifting action of the T-shaped steel piece.

[0044] In this invention, the flipping device 7 can position and flip the two ends of the T-shaped steel piece. The specific structure of the flipping device 7 is as follows: like Figure 11 , Figure 12 and Figure 13 As shown, the flipping device 7 includes a rotating column 71 rotatably mounted on the lifting frame 83. A fixed seat 72 is fixedly connected to the end of the rotating column 71. A clamping slot 73 is symmetrically arranged at the end of the fixed seat 72. A limiting groove 74 adapted to the flange plate 1 is opened on the inner side of the clamping slot 73. The limiting groove 74 of the clamping slot 73 and the flange plate 1 are in clearance fit. The flange plate 1 can slide axially along the limiting groove 74. The flange plate 1 can pass smoothly through the clamping slot 73. A vertical frame 75 is fixedly mounted on the clamping slot 73. Vertical rollers 76 are symmetrically mounted on the vertical frame 75. The web plate 2 of the T-shaped steel part can pass through the area between the two vertical rollers 76. The vertical rollers 76 realize the lateral limiting of the web plate 2. A horizontal roller 77 is rotatably mounted on the top of the vertical frame 75. The horizontal roller 77 presses against the top of the web plate 2 and rolls to realize the height limiting of the web plate 2.

[0045] The positioning process of the T-shaped steel piece is as follows: During the movement of the T-shaped steel piece towards the downstream end of the conveying device 6, its flange plate 1 simultaneously passes through the limiting groove 74 of the clamping slot 73, and the web plate 2 passes through the area between the two vertical rollers 76 on the vertical frame 75. When the T-shaped steel piece has completely moved to the top of the conveying device 6, both ends of the T-shaped steel piece are just locked in the clamping slot 73, completing the positioning before flipping. In the above structure, the clamping slot seat 73 can rise or fall together with the lifting frame 83, thereby driving the T-shaped steel piece to rise and fall synchronously; at the same time, the rotating column 71 can rotate around its own axis, and when rotating, it drives the fixed seat 72 and the clamping slot seat 73 to flip together, thereby driving the positioned T-shaped steel piece to complete the flipping action.

[0046] Among them, the vertical roller 76, the horizontal roller 77 and the clamping groove seat 73 are all located away from the welding point between the web plate 2 and the flange plate 1 to avoid contact.

[0047] To achieve a 180° rotation of the rotating column 71, the present invention employs the following structural design: like Figures 10-13 As shown, a rotating wheel 78 is rotatably sleeved on the outer side of the rotating column 71, and a first force-bearing protrusion 79 and a second force-bearing protrusion 710 are fixedly installed on the outer side of the rotating wheel 78; a tension rod 711 is fixedly connected to the end of the rotating column 71 along its radial direction, and an installation rod 712 is vertically fixedly connected to the end of the tension rod 711; a connecting plate 713 is fixedly connected to the bottom of the lifting frame 83, and a fixed rod 714 is rotatably connected to the connecting plate 713; the installation rod 712 is parallel to the fixed rod 714, and several rotating rings 715 are evenly arranged on the installation rod 712; a spring 716 is correspondingly connected between the rotating ring 715 and the fixed rod 714; the spring 716 is always in a stretched state to provide tension for the reset of the rotating column 71; a limiting seat 717 is fixedly installed on the side of the lifting frame 83 to limit the rotation angle of the installation rod 712, thereby limiting the flip angle of the rotating column 71.

[0048] A transverse slide rail 718 is fixedly installed on the second gantry frame 81. A slide block 719 is slidably mounted on the bottom of the transverse slide rail 718. A first force-applying rod 720 and a second force-applying rod 721 are fixedly connected to the bottom of the slide block 719 respectively. A gap is reserved between the first force-applying rod 720 and the second force-applying rod 721. A third adjusting cylinder is connected to the end of the slide block 719. The slide block 719 is fixedly connected to the drive end of the third adjusting cylinder. By extending and retracting the third adjusting cylinder, the slide block 719 can be moved left and right along the transverse slide rail 718, thereby adjusting the horizontal position of the first force-applying rod 720 and the second force-applying rod 721.

[0049] In the initial state, the positional relationship of each component is as follows: the first force-applying rod 720 is located on the left side, and the second force-applying rod 721 is located on the right side; the first force-receiving protrusion 79 is located above the second force-receiving protrusion 710, both of which are located on the right side of the rotating wheel 78, and the first force-receiving protrusion 79 is aligned with the direct below of the second force-applying rod 721. The specific process of flipping and resetting the T-shaped steel component is as follows: Forward rotation (180° clockwise rotation): The lifting frame 83 rises upward under the drive of the second lifting cylinder, driving the rotating column 71, fixed seat 72, clamping slot seat 73, and the positioned T-shaped steel piece to rise together; during the rising process, if... Figure 14 As shown (the dashed lines in the figure represent the first and second force-bearing protrusions 79 and 710 after clockwise rotation and passing through the gap), the first force-bearing protrusion 79 gradually approaches the second force-applying rod 721. When they contact each other, the second force-applying rod 721 applies a pushing force to the first force-bearing protrusion 79, pushing the rotating wheel 78 and the rotating column 71 to rotate clockwise. During the rotation, the first and second force-bearing protrusions 79 and 710 gradually pass through the gap between the first and second force-applying rods 720 and 721. At the same time, the rotating column 71 drives the tension rod 711 and the mounting rod 712 to rotate clockwise. The mounting rod 712, which is initially horizontal, gradually moves away from the fixed rod 714, and the spring 716 is further stretched. When the mounting rod 712 rotates to a vertical position and continues to rotate clockwise... When the clock hand rotates a small angle, the first force-bearing protrusion 79 and the second force-bearing protrusion 710 completely pass through the gap, and the second force-applying rod 721 no longer applies a pushing force to the first force-bearing protrusion 79. At this time, under the tension of the spring 716, the mounting rod 712 continues to rotate clockwise until it returns to a horizontal state. During this process, the limiting seat 717 limits the rotation angle of the mounting rod 712 to ensure that the rotating column 71 just completes a 180° clockwise rotation. After the flip is completed, the first force-bearing protrusion 79 and the second force-bearing protrusion 710 both rotate to the left side of the rotating wheel 78, and the second force-bearing protrusion 710 is located directly above the first force-bearing protrusion 79. The two are aligned directly above the gap between the first force-applying rod 720 and the second force-applying rod 721, and the T-shaped steel part completes a 180° flip simultaneously. After flipping and resetting for transport: After the T-shaped steel piece is flipped, the lifting frame 83 descends under the drive of the second lifting cylinder, driving the flipping device 7 and the T-shaped steel piece to descend together; during the descent, the first force-bearing protrusion 79 and the second force-bearing protrusion 710 pass through the gap between the first force-applying rod 720 and the second force-applying rod 721; when the T-shaped steel piece descends to the point where its bottom is just aligned with the top surface of another flange plate 1 to be assembled, the horizontal roller 77 and the vertical roller 76 rotate synchronously, driving the T-shaped steel piece to move upstream until the T-shaped steel piece moves directly above the flange plate 1; The flipping device 7 resets and flips (180° counterclockwise rotation): The third adjusting cylinder is driven, causing the slide block 719 to move along the transverse slide rail 718, adjusting the positions of the first force-applying rod 720 and the second force-applying rod 721, so that the first force-applying rod 720 is aligned directly above the second force-receiving protrusion 710; subsequently, the lifting frame 83 rises again, causing the flipping device 7 to rise together, as... Figure 15As shown (the dashed lines in the figure represent the first and second force-bearing protrusions 79 and 710 after they have rotated counterclockwise and passed through the gap), during the upward movement, the second force-bearing protrusion 710 gradually approaches the first force-applying rod 720. When the two contact, the first force-applying rod 720 applies a pushing force to the second force-bearing protrusion 710, causing the rotating wheel 78 and the rotating column 71 to rotate counterclockwise. During the rotation, the first and second force-bearing protrusions 79 and 710 pass through the gap again. At the same time, the rotating column 71 drives the tension rod 711 and the mounting rod 712 to rotate counterclockwise, and the mounting rod 712 gradually moves away from the fixed position. Rod 714 and spring 716 are stretched; when the mounting rod 712 rotates to a vertical position and continues to rotate counterclockwise by a small angle, the force-bearing protrusion completely passes through the gap, and the first force-applying rod 720 no longer applies thrust; under the tension of spring 716, the mounting rod 712 continues to rotate counterclockwise until it returns to a horizontal position, and the limiting seat 717 limits the rotation angle again to ensure that the rotating column 71 completes a 180° counterclockwise rotation; after the rotation is completed, the first force-bearing protrusion 79 and the second force-bearing protrusion 710 are both reset to the right side of the rotating wheel 78, and the clamping slot seat 73 and the flipping device 7 are reset to their initial state; Lifting and Reset: Finally, the lifting frame 83 descends under the drive of the second lifting cylinder, which in turn lowers the clamping slot seat 73 to the initial position. The third adjusting cylinder resets the slide seat 719, completing the entire flipping and reset process.

[0050] In summary, the main implementation process of this invention is as follows: 1. Initial loading and preliminary alignment: The flange plate 1 is conveyed by the loading device 3 to the designated position between the first mounting base 41 and the second mounting base 411, where it is stably supported by the first bottom support wheel 415 to ensure that the flange plate 1 remains horizontal. Subsequently, the web plate 2 is placed vertically and stably on the top surface of the flange plate 1 through the hoisting structure, completing the initial loading operation. Next, the first adjustment cylinder is activated, driving the movable seat 43 to move inward, simultaneously driving the first alignment wheel 44 and the second alignment wheel 45 to move inward. At the same time, the second adjustment cylinder is activated, driving the movable plate 414 to move inward, driving the third alignment wheel 412 and the fourth alignment wheel 413 to move inward, until the first alignment wheel 44 and the third alignment wheel 412 work together to form a stable clamp on the flange plate 1, and the second alignment wheel 45 and the fourth alignment wheel 413 work together to form a stable clamp on the web plate 2, completing the side limit alignment of the flange plate 1 and the web plate 2. 2. Length Alignment and Height Fixing: Each drive motor starts synchronously, driving the first alignment wheel 44, the second alignment wheel 45, the third alignment wheel 412, the fourth alignment wheel 413 and the first bottom support wheel 415 to rotate synchronously, smoothly driving the flange plate 1 and the web plate 2 to move forward together until the ends of the flange plate 1 and the web plate 2 abut against the limit bolt 418, completing the alignment in the length direction; after alignment, the first lifting cylinder 46 starts, driving the lifting plate 47 to drive the top pressure wheel 410 to move downward, pressing the web plate 2 tightly against the flange plate 1, realizing the height direction limit and fixation of the two, thus completing all alignment processes; 3. First welding and T-shaped steel component transportation: After the alignment process is completed, the welding assembly 5 is started. Its head passes through the through-hole 420 of the side mounting frame 419 and is aligned with the joint between the flange plate 1 and the web plate 2 to perform welding operations, gradually forming the T-shaped steel component. After the initial welding is completed and the weld is initially formed, the top pressure wheel 410 is lifted and released under the drive of the lifting plate 47. Subsequently, each alignment wheel and the first bottom support wheel 415 continue to rotate, driving the T-shaped steel component to move slowly downstream. During the movement, the welding assembly 5 continues to weld the joint between the flange plate 1 and the web plate 2. 4. Transferring T-shaped steel parts to the flipping station: Driven by the coordinated rotation of the first alignment wheel 44, the second alignment wheel 45, the third alignment wheel 412, the fourth alignment wheel 413 and the first bottom support wheel 415, the T-shaped steel parts gradually move onto the second bottom support wheel 62 of the transport device 6; then, under the stable support of the second bottom support wheel 62 and the lateral limiting and driving action of the fifth alignment wheel 63, the T-shaped steel parts slowly move towards the downstream end of the transport device 6 until they are completely above the transport device 6, and both ends are clamped in the clamping slots 73 of the flipping device 7, completing the positioning before flipping and waiting for the flipping operation; 5. T-shaped steel piece forward rotation: The lifting frame 83 rises smoothly upward under the drive of the second lifting cylinder, simultaneously driving the rotating column 71, fixed seat 72, clamping slot seat 73 and the positioned T-shaped steel piece to rise together, so that the T-shaped steel piece is separated from the surface of the transport device 6; during the rising process, under the coordinated action of the force-applying rod, force-bearing protrusion, spring 716 and limit seat 717, the rotating column 71 completes a 180° clockwise rotation, driving the T-shaped steel piece to simultaneously achieve a 180° rotation; 6. Loading the second flange plate 1 and docking with the T-shaped steel piece: After the T-shaped steel piece is flipped, the loading device 3 loads another flange plate 1 to be assembled into the designated position between the first mounting base 41 and the second mounting base 411. Then, the lifting frame 83 descends smoothly under the drive of the second lifting cylinder, driving the flipping device 7 and the flipped T-shaped steel piece to descend together. When the bottom of the T-shaped steel piece is aligned with the top surface of the flange plate 1, the horizontal roller 77 and the vertical roller 76 rotate synchronously, driving the T-shaped steel piece to move upstream until the T-shaped steel piece moves directly above the flange plate 1, completing the positioning before docking. 7. Alignment of the T-shaped steel component with the second flange plate 1: The first adjusting cylinder is activated again, driving the movable seat 43 to move inward, causing the first alignment wheel 44 and the second alignment wheel 45 to move inward; simultaneously, the second adjusting cylinder is activated, driving the movable plate 414 to move inward, causing the third alignment wheel 412 and the fourth alignment wheel 413 to move inward, until the first alignment wheel 44 and the third alignment wheel 412 work together to form a stable clamping on the second flange plate 1, and the second alignment wheel 45 and the fourth alignment wheel 413 work together to form a stable clamping on the web plate 2 of the T-shaped steel component. After completing the side limit alignment of both parts, each drive motor starts, driving each alignment wheel and the first bottom support wheel 415 to rotate synchronously, driving the flange plate 1 and the web plate 2 of the T-shaped steel part to move forward together until the ends of both parts abut against the limit bolt 418, completing the alignment in the length direction; after the alignment is completed, the first lifting cylinder 46 starts, driving the lifting plate 47 to drive the top pressure wheel 410 to move downward, pressing the web plate 2 of the T-shaped steel part tightly against the flange plate 1, achieving height direction limit fixation, and completing all alignment processes of the T-shaped steel part and the second flange plate 1. 8. Reset and Second Welding of Tilting Device 7: After the alignment is completed, the third adjusting cylinder is driven to move the slide block 719 along the transverse slide rail 718, adjusting the positions of the first force rod 720 and the second force rod 721 so that the first force rod 720 is aligned with the top of the second force-bearing protrusion 710; then, the lifting frame 83 rises again, driving the tilting device 7 to rise together. During the rise, the rotating column 71 completes a 180° counterclockwise rotation under the coordinated action of the force rod, the force-bearing protrusion, the spring 716 and the limiting seat 717, driving the tilting device 7 to reset to the initial state; at the same time, the welding assembly 5 starts, aligning the T-shaped steel piece with the joint of the second flange plate 1 for welding operation, gradually forming the H-shaped steel; after the initial welding is completed, the top pressure wheel 410 rises and releases under the drive of the lifting plate 47, and each alignment wheel and bottom support wheel continue to rotate, driving the H-shaped steel to move slowly downstream. During the movement, the welding assembly 5 continues to weld. 9. Finished Product Unloading and Equipment Reset: After all welding operations are completed, the H-beam gradually moves upstream under the coordinated rotation of the first alignment wheel 44, the second alignment wheel 45, the third alignment wheel 412, the fourth alignment wheel 413, the first bottom support wheel 415, the second bottom support wheel 62, and the fifth alignment wheel 63. Finally, it is transported to the unloading area by the loading device 3 to complete the finished product unloading. Afterward, the lifting frame 83 descends under the drive of the second lifting cylinder, driving the clamping slot seat 73 to descend to the initial position. At this point, the entire process of H-beam alignment, welding, flipping, secondary alignment, secondary welding, and unloading is completed, and the equipment returns to its initial state, ready for the next round of operations.
