Technical Field

[0001] The utility model relates to the technical field of strip steel production, in particular to a strip steel turning device for a cold-rolled strip steel production line. Background Art

[0002] Strip steel is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrialized production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width and its length varies slightly depending on the size of each roll. Strip steel needs to be turned over during production.

[0003] The Chinese authorized announcement number CN215467086U is a strip turning device for a cold-rolled strip production line. Due to the smooth surface of the strip, the strip is easily turned and misaligned, causing transportation difficulties, which reduces the efficiency of the strip turning device of the cold-rolled strip production line. The utility model can assist in positioning the strip when turning it by arranging an electric push rod and an electromagnet, avoiding transportation difficulties caused by turning and misalignment of the strip, and improving the efficiency of the strip turning device of the cold-rolled strip production line.

[0004] There are still certain shortcomings in use. When flipping the strip, the length of the flip frame cannot be adjusted according to the actual length of the strip, thereby reducing the practicality and use range of the strip when flipping. At the same time, when clamping the strip, only the two sides of the strip can be clamped, and the clamping effect of the strip is limited. The strip will still loosen when flipping. At the same time, when flattening the strip, the pressure wheel is only fixed by a spring, the pressure wheel may accidentally loosen, reducing the flattening quality of the strip.
