Description

Technical Field

[0001] This invention provides a T-profile assembly method, primarily applicable to the shipbuilding industry. Specifically, it relates to a platform and method for assembling arc-shaped combined T-profile panels and webs. Background Technology

[0002] The arc-shaped composite T-section of marine products is assembled from a face plate and a web plate, and is usually used as a reinforcing rib for curved outer plates. Based on its position on the inner or outer side of the outer plate, the T-section can be divided into inner ribs and outer ribs. The face plate and web plate of the arc-shaped composite T-section are formed from steel plates by CNC cutting. To improve steel plate utilization, a complete circular T-section is usually composed of 3-4 equally divided arc-shaped composite T-sections. The face plate is rolled to the required arc radius, and after beveling on the web plate, the face plate and web plate are positioned according to the specifications and dimensions of the composite T-section before welding to form 3-4 equally divided arc-shaped composite T-sections. Post-weld deformation needs to be corrected using a hydraulic press. After passing the correction, the 3-4 equally divided arc-shaped composite T-sections are positioned and assembled into a complete circle. Finally, the ridge deformation of the web plate and the perpendicularity of the face plate are corrected again. Traditional assembly processes require forming T-profiles into 3-4 equal parts, which are intermediate products. This increases the assembly process and prevents the T-profiles from being assembled into a complete circle in one go, resulting in low efficiency. In addition, the lack of clamping fixtures makes it difficult to control deformation during the welding process, requiring multiple corrections, which consumes a lot of time and reduces the mechanical properties of the T-profiles.

[0003] Patent CN2006936704U describes a tooling for processing T-profiles, which can be used to process straight T-profiles on a multi-hole platform, but cannot be adapted to the assembly of the face and web of curved T-profiles; Patent CN 106239006B describes a method for manufacturing T-profiles, which is applicable to the processing of straight T-profiles, but cannot be applied to the manufacturing of curved T-profiles with different bending radii, resulting in insufficient versatility and higher costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies and the issues of positioning and assembly efficiency of the faceplate and web of curved composite T-profiles, this invention provides a platform and method for assembling the faceplate and web of curved composite T-profiles. This assembly platform, through clamping fixtures, is adaptable to the fabrication of curved composite T-profiles with different radii, thus solving the technical problems of assembling the faceplate and web of curved composite T-profiles.

[0005] The solution adopted by this invention to solve the technical problem is:

[0006] An assembly platform for the panel and web of a circular arc combined T-profile includes a central pier, radial guide rails, reinforced radial guide rails, and clamping fixtures. The circular arc combined T-profile is composed of a T-profile panel and a T-profile web. Based on the characteristics of the inner and outer sides of the outer panel, the circular arc combined T-profile is divided into inner ribs and outer ribs.

[0007] A central support is set in the middle of the assembly platform to locate the center of the arc-shaped T-shaped panel. Radial guide rails are evenly distributed around the central support at equal angles. Between adjacent radial guide rails, at a position away from the central support, additional radial guide rails are evenly distributed at equal angles.

[0008] The upper surfaces of the center pier, radial guide rails, and reinforced radial guide rails are at the same level; the upper surfaces of the radial guide rails and reinforced radial guide rails are engraved with panel radius lines and values;

[0009] The radial guide rail and the encrypted radial guide rail are provided with grooves for assembling and clamping fixtures to hold the T-profile panel and the T-profile web; the clamping fixture has a limiting guide rail that can be inserted and pushed out from both ends of the radial guide rail / encrypted radial guide rail, and the direction of the clamping fixture can be changed, which is suitable for clamping inner ribs and outer ribs.

[0010] To further address the technical problem addressed by this invention, the present invention provides a method for assembling the web of a circular arc combined T-profile panel, comprising the following steps:

[0011] Step 1: Based on the characteristics of the inner and outer ribs of the arc-shaped T-profile to be assembled, adjust the direction of the clamping fixture. According to the radius value of the T-profile panel, align the positioning mark on the clamping fixture with the radius mark and the radius value corresponding to the value on the panel.

[0012] Step 2: Adjust the height of the lifting stud according to the half-width value of the T-profile panel, so that the upper end of the lifting stud is aligned with the half-width marking line and the corresponding half-width value on the panel.

[0013] Step 3: Place the T-profile panel to be assembled into the open slot of the clamping fixture, adjust the distance between the two ends of the T-profile panel and the clamping fixture to be equal, press down the U-shaped clamping plate of the panel, and tighten the panel fastening studs to press the T-profile panel tightly against the vertical column.

[0014] Step 4: Place the T-profile web flat on the horizontal beam of the clamping fixture, adjust the welding gap between the T-profile web and the T-profile panel, align the ends of the T-profile web with the ends of the T-profile panel, push the web U-shaped clamping plate so that the T-profile web is tightly against the U-shaped groove of the web U-shaped clamping plate, and tighten the web fastening studs to fasten the T-profile web to the horizontal beam;

[0015] Step 5: Weld the bevels of the web and face plate of the T-profile. According to the welding requirements, multiple automatic submerged welding machines or multiple people can manually weld on the web of the T-profile simultaneously in the same direction and at equal intervals.

[0016] Step 6: Weld the butt bevel of the web of the T-profile, and weld the butt bevel of the face plate of the T-profile;

[0017] Step 7: After welding is completed, release the U-shaped clamping plate of the panel and the U-shaped clamping plate of the web. When it is necessary to flip over and perform air gouging and welding, repeat steps 3-7.

[0018] Step 8: Use a rib straightening machine to correct the ridge deformation of the web and the perpendicularity of the face plate.

[0019] The positive effects of this invention are that, due to the use of clamping fixtures on the assembly platform, it is applicable to the assembly of arc-shaped combined T-profiles with different bending radii, exhibiting high versatility. The clamping fixtures can be used for clamping inner and outer ribs, and the engraved lines on them improve the speed of assembly positioning. Furthermore, the platform is flush with the ground plane, offering high convenience. When not in use, it can be used for other purposes, improving the utilization rate of the assembly jig. The assembly method reduces intermediate steps in positioning and assembly, allowing multiple welding machines and personnel to work simultaneously, improving assembly efficiency. The clamping fixtures also help control welding deformation, reducing the number of corrections and saving construction costs. This invention is suitable as an assembly platform and method for the panel and web of arc-shaped combined T-profiles. Attached Figure Description
