This application relates to the field of pipe fitting inspection technology, and in particular to an automated visual inspection device for pipe fitting production lines. The device includes a frame with a base plate on one side. A sliding plate is slidably mounted on the base plate, and a clamping component is mounted on the sliding plate on one side. Multiple evenly distributed uprights are arranged on the frame, with one upright on one side mounted on the sliding plate. Clamping components are mounted on each of the uprights. Each clamping component includes a support plate mounted on an upright, with a V-shaped groove on the support plate. A connecting frame, L-shaped in shape, is mounted on one side of the support plate, and a guide rod passes through the connecting frame. The guide rod is located on a pressure plate directly above the support plate. The device uses a downward-pressing cylinder to push the pressure plate downward, forming an annular clamping space between the V-shaped pressure groove and the V-shaped support groove. The self-centering effect of the V-shaped surface ensures the position of the pipe fitting axis. The coordinated force from multiple clamping points evenly distributes the weight of the pipe fitting to each support point, effectively suppressing bending deformation of long pipe fittings.

This invention provides a comprehensive, coordinated control method for reducing the total curvature of long, fixed-length small square billets. It covers three stages: continuous casting process optimization, cooling bed control, and slow cooling during stacking. Based on the metallurgical mechanism of bainitic phase transformation, a complete temperature control chain is constructed to systematically eliminate multiple sources of curvature, including uneven cooling, phase transformation stress, and additional stress from stacking. Compared with existing technologies, this invention requires no additional specialized equipment and, without significantly increasing production costs, ensures that the total curvature of small square billets is stably controlled within 60mm, with a curvature per meter not exceeding 10mm. This significantly improves product quality, production efficiency, and production safety, effectively solving technical problems such as difficulty in charging the heating furnace, rolling defects, high scrap rates, and increased production costs caused by excessive curvature of small square billets, thus providing qualified billets for subsequent steel rolling production.
