Currently, common plate rolling machines are divided into three-roller and four-roller types.

[0003] Four-roll plate rolling machines can usually adjust the roller spacing according to the plate rolling requirements. However, the adjustment has the problem of poor precision. The rollers at the bottom of the plate rolling machine are not easy to adjust the spacing flexibly according to the thickness of the plate. After adjustment, it is not easy to accurately detect the spacing size, thus affecting the accuracy and flexibility of plate rolling.

[0004] There is an urgent need for a four-roll plate bending machine with adjustable roller spacing to solve the technical defects mentioned above. Utility Model Content
