[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example 1: A segmented high-precision irregular-shaped welded pipe mold structure for a welded pipe unit, such as... Figures 1-4 As shown, it includes a mold base 1, on which a mold body and a positioning component 3 are provided;

[0030] The mold body consists of four segmented molds 2, which are mounted on the positioning assembly 3.

[0031] The positioning component 3 includes several sets of positioning seats 31, all of which are installed on the mold base 1. A crossbeam limiting seat 32 is provided between each two adjacent sets of positioning seats 31, and the segmented mold 2 is installed on each adjacent crossbeam limiting seat 32.

[0032] The mold base 1 has through holes on both sides, and the four sets of positioning seats 31 near the left and right side walls of the mold base 1 also have through holes on their ends. Several sets of positioning seats 31 are installed on the mold base 1 through the limiting pins 33 at both ends of the mold base 1.

[0033] The upper surface of the crossbeam limit seat 32 is provided with a high-precision positioning plane. The bottom of the segmented mold 2 is closely fitted with the positioning plane and fixed by fastening bolts.

[0034] In use, place the mold base 1 stably in a suitable installation position. Align the bottom of the positioning seat 31 with the corresponding installation position on the mold base 1 according to the design requirements, so that the through holes on the ends of the four sets of positioning seats 31 near the left and right side walls of the mold base 1 correspond one-to-one with the through holes on both sides of the mold base 1. Use the limiting pins 33 to sequentially insert the through holes at both ends of the mold base 1 and the corresponding through holes on the ends of the positioning seats 31 to ensure that the positioning seats 31 are firmly installed on the mold base 1. Then, install the crossbeam limiting seat 32 between each pair of adjacent positioning seats 31, ensuring that the high-precision positioning plane on its upper surface is horizontal. Place the four segmented molds 2 on the corresponding adjacent crossbeam limiting seats 32, so that the bottom of the segmented molds 2 is aligned with the crossbeam limiting seats 32. The high-precision positioning planes of the 2 sections are tightly fitted together. Then, fastening bolts are passed through the corresponding holes on the section mold 2 and the crossbeam limit seat 32. The bolts are then tightened with a wrench to ensure that the section mold 2 and the crossbeam limit seat 32 are fixedly connected. When a section mold 2 is found to be worn or damaged and needs to be replaced, first use a wrench to loosen the fastening bolts connecting the section mold 2 and the crossbeam limit seat 32. Remove the worn section mold 2 from the crossbeam limit seat 32. Place the new section mold 2 on the corresponding crossbeam limit seat 32, ensuring that its bottom is tightly fitted with the high-precision positioning plane of the crossbeam limit seat 32. Use fastening bolts to re-fix the section mold 2 on the crossbeam limit seat 32, ensuring that the installation is secure.

[0035] like Figures 1-4 As shown, the forming surface 21 of the segmented mold 2 is precision machined according to the cross-sectional shape of the irregular welded pipe. It has curved surfaces and raised structures that are adapted to the shape of the corresponding parts of the irregular welded pipe. Through the high-precision machining of the forming surface 21, the dimensional error of the welded pipe caused by the mold shape deviation can be effectively reduced. Moreover, through the precise curved surface and raised design, the deformation process of the strip steel can be precisely controlled to avoid problems such as uneven thickness and shape deviation, thereby improving the overall forming accuracy of the irregular welded pipe.

[0036] like Figures 1-4As shown, the segmented mold 2 has positioning parts 22 protruding from both ends. The positioning parts 22 at both ends of the segmented mold 2 are fitted into the grooves 321 of the crossbeam limit seats 32 at both ends. In use, the positioning parts 22 and the grooves 321 fit together to provide a precise installation position for the segmented mold 2. During installation, by accurately embedding the positioning parts 22 into the grooves 321, the positional deviation of the segmented mold 2 on the crossbeam limit seat 32 can be strictly controlled within a very small range, so that the segmented mold 2 can be accurately placed in the predetermined position, ensuring the relative positional accuracy between each segmented mold 2, and thus ensuring that the entire mold body can form and process the strip steel according to the design requirements.

[0037] like Figures 1-4 As shown, the mold base 1 is provided with two sets of support blocks 4. The upper surfaces of the two sets of support blocks 4 abut against the crossbeam limiting seats 32 located at the left and right ends. At the same time, the support blocks 4 and the crossbeam limiting seats 32 are provided with matching fixing holes. The two are connected by fastening bolts. In use, the crossbeam limiting seats 32 can bear the pressure generated by the segmented mold 2 and the strip forming during the mold operation. The support blocks 4 provide additional support points for the crossbeam limiting seats 32, and transfer part of the pressure borne by the crossbeam limiting seats 32 to the mold base 1, so as to prevent the crossbeam limiting seats 32 from deforming or displacing due to excessive force.

[0038] Example 2: A segmented high-precision irregular-shaped welded pipe mold structure for a welded pipe unit, such as... Figures 1-4 As shown, the mold base 1 is also provided with an elastic support structure 5. The elastic support structure 5 includes several sets of springs 51 installed on the mold base 1, wherein every two sets of springs 51 are connected to a support plate 52, and the support plate 52 is adapted to the bottom surface of the positioning seat 31.

[0039] Several sets of springs 51 are mounted on the assembly plate 53, which is detachably mounted on the mold base 1.

[0040] The mold base 1, the support plate 52 and the assembly plate 53 are all provided with through cavities. The guide post 54 passes through the mold base 1 and the assembly plate 53 in sequence and is installed in the screw cavity of the support plate 52 in a spiral connection manner.

[0041] In actual production, there is usually a certain clearance between the mounting holes on the mold base 1, the positioning seat 31, and the limiting pin 33. This is to facilitate installation and disassembly. However, when the mold is subjected to large pressure or vibration, the positioning seat 31 may move slightly downward along the limiting pin 33. At this time, the elastic support structure 5 comes into play. The support plate 52 compresses the spring 51 under pressure. The spring 51 undergoes elastic deformation, absorbing and buffering part of the pressure, reducing the impact force on the mold, and ensuring the stability and molding accuracy of the mold.

[0042] During the mold operation, the strip forming process generates significant pressure and impact. These forces are transmitted to the positioning seat 31 and the support plate 52. The guide post 54 ensures that the support plate 52 moves along a predetermined direction when subjected to force, preventing deviation or wobbling.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
