Description

Technical Field

[0001] This utility model relates to the technical field of H-beam steel component processing equipment, specifically an H-beam steel assembly machine that prevents deformation. Background Technology

[0002] In the field of steel structure manufacturing, H-beams are a common structural component widely used in construction, bridges, and shipbuilding projects. The assembly process of H-beams is a crucial step in forming the web and upper and lower flanges through welding. The assembly accuracy directly affects the subsequent welding quality and the mechanical properties of the finished product. Traditional H-beam assembly machines typically employ fixed pressure roller structures or simple single-point adjustment mechanisms, which are insufficient to effectively meet the assembly requirements of H-beams of different specifications. Especially when the flange thickness or width varies, the adjustment flexibility of the pressure roller spacing is inadequate, easily leading to the following problems: Poor adaptability: For different specifications of H-beams, frequent manual replacement or adjustment of the pressure roller positions is required, which is cumbersome and inefficient, making it difficult to meet the demands of modern production lines for flexible manufacturing. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an H-beam assembly machine that prevents deformation, which can quickly adjust the position of the pressure rollers for H-beams of different specifications and achieve rapid locking.

[0004] The objective of this utility model is achieved through the following technical solution: An H-beam erecting machine to prevent deformation, comprising: A first base, on which a support frame is mounted; Left and right side panels, which are connected to the side wall of the assembly frame by connectors; A lead screw, the two ends of which are rotatably connected to two side plates; Two first nut seats, the first nut seats being threaded into the lead screw; Two diagonal braces are distributed in a figure-eight shape. The top ends of the two diagonal braces are hinged to the corresponding first nut seats, and the bottom ends of the two diagonal braces are hinged to pressure plates. The first pressure roller is rotatably connected to the first base; The second pressure roller is rotatably connected to the bottom of the pressure plate; The drive mechanism is installed in the upright frame and is used to drive the lead screw to rotate. The two first nuts are synchronously close to or away from the lead screw, and the first pressure roller is pushed to move vertically through the two diagonal braces to adjust the distance between the first pressure roller and the second pressure roller.

[0005] Preferably, the lead screw is a bidirectional lead screw, with the threads of the two first nut seats having opposite directions to achieve synchronous symmetrical motion.

[0006] Preferably, the drive mechanism includes: The second mounting plate is fixedly connected to the side plate, and the second mounting plate is provided with a first through groove. A first housing is fixed in a first through groove. A first synchronous pulley and a second synchronous pulley are rotatably connected inside the first housing. The first synchronous pulley and the second synchronous pulley are connected by a synchronous belt. The first synchronous pulley is fixedly connected to a threaded rod. The first motor is fixedly connected to the bottom of the second mounting plate. The first motor is used to drive the first synchronous pulley to rotate inside the first housing, so as to drive the second synchronous pulley and the threaded rod to rotate coaxially.

[0007] Preferably, the upright frame is provided with guide shafts on opposite sides, and the two ends of the guide shafts are connected to the side wall of the upright frame through fixed seats. The guide shaft pressure plate is slidably engaged to restrict the pressure plate to move only in the vertical direction.

[0008] Preferably, the surfaces of the first and second pressure rollers are provided with anti-slip textures or rubber layers to enhance the clamping stability of the H-beam.

[0009] Preferably, the axes of the first and second pressure rollers are parallel to each other and perpendicular to the feeding direction of the H-beam to ensure alignment during the assembly process.

[0010] Preferably, the side wall of the support frame is provided with a first groove, a slider is slidably connected in the first groove, a threaded rod is fixedly connected to the side of the slider, and a second nut seat is threaded to the other end of the threaded rod that passes through the side plate.

[0011] The beneficial effects of this utility model are: In this application, a drive mechanism controls the rotation of the lead screw, causing the two first nut seats to move synchronously closer or further apart. A figure-eight shaped distribution of diagonal braces pushes the pressure plate and the second pressure roller up and down, achieving precise adjustment of the distance between the first and second pressure rollers. This ensures a tight fit between the flanges and webs of H-beams of different specifications, reducing welding deformation and improving assembly accuracy. The symmetrically distributed diagonal brace structure ensures even distribution of clamping force, preventing twisting or displacement of the H-beams caused by unilateral force, effectively preventing deformation during assembly, and ensuring that the straightness and cross-sectional dimensions of the H-beams meet requirements. The threaded fit between the lead screw and the nut seat, combined with the automatic control of the drive mechanism, allows for rapid adjustment of the pressure roller distance, eliminating the need for frequent manual replacement or adjustment, significantly improving production efficiency and adapting to the assembly needs of H-beams of different thicknesses and widths. The rigid support structure of the uprights and side plates, combined with the high stability of the lead screw drive, ensures a smooth and undisturbed adjustment process, reducing mechanical wear and extending equipment lifespan. The automatic control of the lead screw rotation by the drive mechanism reduces errors and labor intensity from manual adjustments, improving the automation level of the production line. This system is suitable for modern intelligent welding production lines. This invention achieves high precision, high efficiency, and high stability in H-beam assembly by optimizing the pressure roller adjustment mechanism, effectively solving the problems of easy deformation and inconvenient adjustment in traditional assembly machines.

[0013] Example 1 like Figure 1 and Figure 2As shown, an H-beam erecting machine for preventing deformation is provided, including a first base 1, left and right side plates 4, a lead screw 6, two diagonal braces 8 distributed in a V-shape, a first pressure roller 2, a second pressure roller 12, and a drive mechanism 11; the specific connections are as follows: a frame 3 is installed on the first base 1, the side plates 4 are connected to the side wall of the erecting machine frame through connectors 5, the two ends of the lead screw 6 are rotatably connected to the two side plates 4, and two first nut seats 7 are threadedly engaged with the lead screw 6. The lead screw 6 is a bidirectional lead screw 6, and the two first nut seats 7 are threadedly engaged with the lead screw 6. The threads rotate in opposite directions to achieve synchronous symmetrical movement. The tops of the two diagonal supports 8 are hinged to the corresponding first nut seats 7, and the bottoms of the two diagonal supports 8 are hinged to pressure plates 9. The first pressure roller 2 is rotatably connected to the first base 1, and the second pressure roller 12 is rotatably connected to the bottom of the pressure plate 9. The drive mechanism 11 is installed in the upright frame 3. The drive mechanism 11 is used to drive the lead screw 6 to rotate. The two first nut seats 7 move closer or further away from the lead screw 6 synchronously. The two diagonal supports 8 push the first pressure roller 2 to move vertically, adjusting the distance between the first pressure roller 2 and the second pressure roller 12. The drive mechanism 11 includes a second mounting plate 17, a first housing 18, and a first motor 16. The second mounting plate 17 is fixedly connected to the side plate 4. A first through slot is provided on the second mounting plate 17. The first housing 18 is fixed in the first through slot. A first synchronous pulley 13 and a second synchronous pulley 15 are rotatably connected inside the first housing 18. The first synchronous pulley 13 and the second synchronous pulley 15 are connected by a synchronous belt 14. The first synchronous pulley 13 is fixedly connected to the threaded rod 21. The bottom of the first motor 16 is fixedly connected to the second mounting plate 17. The first motor 16 is used to drive the first synchronous pulley 13 to rotate inside the first housing 18, so as to drive the second synchronous pulley 15 and the threaded rod 21 to rotate coaxially. After the first motor 16 (fixed on the second mounting plate 17) is energized, it outputs rotational power. The drive mechanism 11 drives the first synchronous pulley 13 to rotate through the first motor 16, and drives the second synchronous pulley 15 to rotate synchronously through the synchronous belt 14. Since the first synchronous pulley 13 is fixedly connected to the threaded rod 21, the coaxial rotation of the threaded rod 21 is realized. The main body of the mechanism is fixedly supported by the second mounting plate 17. The first housing 18 encapsulates the synchronous pulley and synchronous belt to protect the transmission components. The overall structure is compact and the transmission is precise. It is suitable for mechanical systems that need to convert the rotational motion of the motor into the linear drive of the screw. It adopts an eight-shaped diagonal brace 8 hinge mechanism (diagonal brace 8 + first nut seat 7 + pressure plate 9 combination). The synchronous adjustment of the distance between the two pressure rollers is achieved through the drive of the screw 6, which ensures the perpendicularity of the web and flange of the H-beam steel when they are assembled and effectively suppresses welding deformation. The symmetrical movement of the two first nut seats 7 is coordinated with the transmission of the diagonal brace 8, and the mechanical distribution is balanced, avoiding the eccentric deformation caused by unilateral pressure. The drive mechanism 11 (such as a servo motor) precisely controls the synchronous opposite / reverse movement of the two first nut seats 7 through the screw 6. The diagonal brace 8 converts the horizontal movement into the vertical displacement of the pressure plate 9, realizing the rapid adjustment of the distance of the second pressure roller 12 to adapt to the assembly requirements of plates of different thicknesses.The first pressure roller 2 is fixed to the base, and the second pressure roller 12 is dynamically pressed by the pressure plate 9 to form a stable roller pressure zone. During the assembly process, uniform pressure is continuously applied to counteract the warping caused by welding thermal stress. The rigid connection between the side plate 4 and the assembly frame enhances the overall structural stability and further reduces deformation caused by vibration or external force. It is suitable for high-precision H-beam production lines, and has a significant anti-deformation effect, especially for the assembly of thin-walled or large-section H-beams. Mechanical adjustment is easier to maintain than hydraulic systems, and there is no risk of oil pressure fluctuations. It also has better long-term stability.

[0014] like Figure 1 As shown, in order to constrain the movement trajectory of the pressure plate 9 and make the pressure plate 9 only slide up and down, the upright frame 3 is vertically arranged with guide shafts 10 on both sides. The two ends of the guide shafts 10 are connected to the side wall of the upright frame 3 through fixed seats. The guide shafts 10 slide with the pressure plate 9, thereby restricting the pressure plate 9 to move only in the vertical direction.

[0015] like Figure 1 As shown, in order to further enhance the anti-slip performance between the second pressure roller 12 and the workpiece (i.e., H-beam 19), the surfaces of the first pressure roller 2 and the second pressure roller 12 are provided with anti-slip textures or rubber layers to enhance the clamping stability of the H-beam. The axes of the first pressure roller 2 and the second pressure roller 12 are parallel to each other and perpendicular to the feeding direction of the H-beam to ensure alignment during the assembly process.

[0016] like Figure 3 As shown, the installation position of the side plate 4 on the stand 3 can be adjusted up and down. To facilitate adjustment, a first groove 301 is vertically provided on the side wall of the stand 3. A slider 20 is slidably connected in the first groove 301. A threaded rod 21 is fixedly connected to the side of the slider 20. The other end of the threaded rod 21 passes through the side plate 4 and is threadedly connected to a second nut seat 22. The height adjustment process of the side plate 4 on the stand 3 is as follows: the vertical first groove 301 on the side wall of the stand 3 serves as a sliding track, and the slider 20 connected inside can slide freely up and down along the groove, providing vertical movement guidance for the side plate 4. The threaded rod 21 fixed to the side of the slider 20 passes through the mounting end of the side plate 4. It can be locked or loosened by rotating the second nut seat 22 (which forms a threaded pair with the threaded rod 21). During adjustment: loosen the second nut seat 22, and the side plate 4 can slide with the slider 20 in the first groove 301 to the required height. During locking: tighten the second nut seat 22, and use the thread friction to press the side plate 4 against the side wall of the stand 3 to fix the position. The continuous vertical design of the groove allows the side plate 4 to be locked at any height. Through the cooperation of the slider guide and the threaded locking, the height of the side plate can be quickly adjusted and firmly fixed.
