[0033] See Figures 1 to 4 As shown in the figure, this utility model embodiment provides a reinforced straight seam welded pipe extrusion roller, including a base 1, a welded pipe channel 101 for the straight seam welded pipe to pass through on the base 1, and detachable extrusion roller assemblies 2 are slidably arranged on both sides of the base 1 and at positions corresponding to the welded pipe channel 101.

[0034] To enhance the adjustability of the extrusion roller assembly 2 and meet diverse production needs, the extrusion roller assembly 2 includes a roller mounting base 201, on which the extrusion roller 2021 is rotatably mounted via a mounting roller shaft 202. Simultaneously, a mounting groove 2011 precisely matches the roller mounting base 201 is carefully formed on the side of the base 1, allowing the roller mounting base 201 to slide within this groove. This design provides the extrusion roller assembly 2 with excellent adjustability. Operators can easily move and adjust the position of the extrusion roller 2021 according to the production requirements of different specifications of straight seam welded pipes, greatly expanding the application range of the equipment and effectively improving its adaptability to diverse production scenarios.

[0035] To ensure the stability of the roller mounting base 201 during sliding and prevent offset or wobbling, positioning sliders 203 are securely fixed to both sides of the roller mounting base 201. Positioning grooves 2031, perfectly matching the positioning sliders 203, are correspondingly formed on both sides of the inner wall of the mounting groove 2011. The side of the positioning slider 203 closest to the positioning groove 2031 cleverly moves through the positioning groove 2031 and extends into its interior, achieving a tight and smooth sliding connection with the inner wall of the positioning groove 2031. This ingenious cooperation between the positioning slider 203 and the positioning groove 2031 provides precise guidance and reliable support for the sliding of the roller mounting base 201. During the adjustment of the position of the extrusion roller 2021, offset or wobbling of the roller mounting base 201 is effectively prevented, ensuring the accuracy and stability of the extrusion roller 2021 adjustment, thereby improving the quality of straight seam welded pipe extrusion.

[0036] To ensure stable positioning of the roller mounting base 201 after adjustment and facilitate subsequent maintenance and replacement, a fixing plate 204 for positioning the roller mounting base 201 is securely connected to the top of the roller mounting base 201. Two fixing bolts 2041 are symmetrically installed on the fixing plate 204. Simultaneously, several sets of fixing threaded holes 205 are carefully drilled on the base 1, corresponding to the positions of the fixing bolts 2041. When the roller mounting base 201 is adjusted to the appropriate position, the tight fit between the fixing bolts 2041 and the fixing threaded holes 205 provides stable positioning for the roller mounting base 201, ensuring that the extrusion roller 2021 will not shift due to external forces during the straight seam welded pipe production process. Furthermore, this design also facilitates the maintenance and replacement of the extrusion roller 2021; operators only need to loosen the fixing bolts 2041 to perform related operations, greatly improving work efficiency.

[0037] The above technical solution allows for flexible adjustment of the position of the extrusion roller 2021 according to the production requirements of straight seam welded pipes of different specifications by sliding the roller mounting base 201 into the mounting groove 2011 on the side of the base 1. This greatly improves the applicability of the equipment.

[0038] After adjustment, the roller mounting base 201 is fixedly installed by the top fixing bolt 2041 and the corresponding fixing threaded hole 205 on the top of the base 1, so as to achieve stable positioning of the roller mounting base 201, ensure the stability and accuracy of the extrusion roller, and improve the quality of welded steel pipe.

[0039] When maintenance or replacement of the extrusion roller 2021 is required, the fixing bolt 2041 can be loosened to disengage it from the fixing threaded hole 205, and the roller mounting base 201 can be easily pulled out. The convenient disassembly and assembly design shortens the maintenance and replacement time, reduces labor costs and the impact on production schedule, and effectively improves production efficiency.

[0040] In summary, by sliding the roller mounting base 201 into the mounting groove 2011 on the side of the base 1, the operator can flexibly move and adjust the extrusion roller 2021 on the roller mounting base 201 according to the production needs of straight seam welded pipes of different specifications. This greatly enhances the adaptability of the present invention to diverse production scenarios and effectively improves the applicability of the equipment.

[0041] After the roller mounting base 201 is adjusted, it is precisely fixed in the corresponding fixed threaded hole 205 on the top of the base 1 by means of the fixing bolts 2041 on the top fixing plate 204 of the roller mounting base 201. This achieves stable positioning of the roller mounting base 201 after adjustment, ensuring that the extrusion roller 2021 remains stable during the production of straight seam welded pipe, thereby ensuring the extrusion quality.

[0042] When maintenance or replacement of the extrusion roller 2021 is required, simply loosen the fixing bolt 2041 to disengage it from the fixing threaded hole 205, and the roller mounting base 201 can be easily slid out from the inner wall of the mounting groove 2011. The convenient disassembly and assembly design shortens the time required for maintenance or replacement, reduces labor costs, and improves production efficiency.

[0043] The foregoing has shown and described the basic principles of the present invention.
