Description

Technical Field

[0001] This utility model relates to the field of pressure roller technology, specifically to a coiling pressure roller for a bending straightening machine. Background Technology

[0002] A strip straightener, also known as a tension-bending straightening unit, is an industrial device used for straightening strip steel. Its main functions are to eliminate yield plateaus, prevent slip lines, and improve strip shape. Its structure typically includes bending rolls, straightening rolls, guide rolls, a roll changing device, and a roll lifting system. Some models are equipped with a wet spray system to achieve wet straightening. Common types include two-bend-two-straightening, two-bend-one-straightening, and one-bend-one-straightening, with the two-bend-one-straightening type being the most widely used. This type consists of two bending rolls, one straightening roll, and several guide rolls. This equipment achieves straightening through a combination of bending stress and longitudinal tension, requiring only 1 / 3 to 1 / 5 of the tension required for pure tension, which helps improve the anisotropy of the material. Key technologies include speed adjustment, roll opening adjustment, and multi-point straightening technology, the latter preventing internal cracking of the liquid-core cast billet by dispersing strain. Water-cooled rolls, protective plates, and water-cooled tunnels are used to ensure stable operation under high-temperature conditions. Main roll spare parts include work rolls, support rolls, straightening rolls, and intermediate bending rolls.

[0003] Currently, the tension straightening machine plays a crucial role in aluminum coil production. The coiler provides exit tension, and the coiling pressure rollers hold the coil in place to prevent loosening. Originally, the coiling pressure rollers were mounted on the coiling reducer, relying on a hydraulically driven connecting rod to press the rollers to the outermost circle of the maximum coil diameter, ensuring stability at the tail of the aluminum strip during winding and preventing loose layers from forming during coiling. However, the current equipment has pressure rollers with a length of 800mm and a material width of 1200-1850mm, meaning it can only press a portion of the sheet, with the pressing position in the middle, easily leading to problems such as layer mixing during production. Utility Model Content
