Description

Technical Field

[0001] The utility model relates to the technical field of rolling machines, in particular to a rolling machine for steel plate processing. Background Art

[0002] The rolling machine is used for sheet metal rolling operations. It can roll sheets of different lengths to obtain rolled cylinders with different diameters. Currently, when the sheet metal is being rolled, manual assistance is generally required to adjust the sheet metal feed and feed the sheet metal between the upper and lower rollers. When rolling, the steel plate must be placed straight between the upper and lower rollers so that the sheet metal is clamped between the two pairs of rollers. The equipment starts to clamp and roll the sheet metal.

[0003] For large plates with large size and thin thickness, it is more difficult to feed when the diameter of the rolling cylinder is large, and the plate is not easy to align with the roller during manual operation; and the diameter of the rolling cylinder is large, the plate is thin, and the whole is soft. The rolled part lacks support under the action of gravity and will also be compressed and deformed. Therefore, it is easy to roll sideways and misaligned when rolling. For this reason, we provide a rolling machine for steel plate processing, which is convenient for the rolling machine to assist in rolling the plate to avoid distortion and misalignment after rolling. Utility Model Content
