Technical Field

[0002] In the stainless steel processing industry, the flat plate machine for straightening stainless steel coils is a crucial equipment. Its function is to transform the curled stainless steel sheets into a flat state through the straightening operation to meet the requirements of subsequent processing technology. With the continuous expansion of stainless steel application fields, the flatness and quality standards of stainless steel sheets are becoming more and more stringent; Existing flat machines for straightening stainless steel coils usually use a uniform pressure application method during straightening operations. However, due to differences in material properties or uneven hardness during the production process of stainless steel coils, the physical properties of different parts may fluctuate to a certain extent. When using traditional flat machines for straightening, this uniform pressure application method is difficult to flexibly adjust to the local property changes of the coil, and it is very easy to cause over-straightening during the straightening process, resulting in local thinning of the plate thickness, reduced strength, and even abnormal deformation, which seriously affects the quality of the stainless steel plate and subsequent processing performance, and increases the scrap rate and production costs. At the same time, traditional equipment lacks effective local pressure regulation means, and cannot accurately regulate the pressure in specific areas of the coil. It is difficult to adapt to the complex and changeable stainless steel material processing needs, which to a certain extent limits the efficient development of the industry and the improvement of product quality.
