Abstract
Description
Technical Field
[0001] The invention relates to the technical field of steel billet processing, in particular to a compatible synchronous straightening machine. Background Art
[0002] The existing H-shaped blank straightening technology is mainly based on flat roller straightening, which mainly relies on the flat roller to apply pressure to the flange and drive the flat roller to rotate at the same time to make the H-shaped blank achieve the purpose of straightening. At present, it is widely used on small and medium-sized H-shaped blanks with a width of less than 1300mm, a flange height of less than 510mm, and a web thickness of less than 120mm. However, with the development of society, especially the construction of large-scale domestic venues, factories, cross-sea bridges and cross-river bridges, the demand for H-shaped steel with a width greater than 1300mm, a flange height greater than 510mm, and a web thickness greater than 120mm is increasing. The cost of H-shaped steel formed by welding in the past is relatively high and cannot meet the large-scale use of major projects. For super-large H-shaped blanks, as the web thickens, flange straightening alone cannot meet the requirements of web straightening. Moreover, due to the effect of cooling water, the temperature of the web often reaches 900°C when entering the straightening zone, which increases the overall resistance of the web. The core temperature at the junction of the web and the flange is much higher than 1200°C due to the final solidification, resulting in weak structural strength here. If the flange is straightened with a flat roller, it is possible to cause tearing at the junction of the web and the flange, and such a thick web will also prolapse if there is no support. Therefore, providing a straightening machine that can straighten super-large H-shaped blanks is an urgent problem to be solved in this field. Summary of the invention
