Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled plate curling mechanisms, in particular to a cold-rolled plate curling mechanism. Background Art

[0002] In the processing and production of cold-rolled plates, we need to perform curling operations on the cold-rolled plates, so a cold-rolled plate curling mechanism is required.

[0003] For example, a cold-rolled plate curling mechanism with patent publication number CN219597794U is provided, which places the cold-rolled plate on the upper end of the lifting plate by setting multiple second rollers and a first motor, and places the cold-rolled plate between the multiple second rollers through a fixed frame. The first motor is turned on to rotate the second roller, and the cold-rolled plate can be quickly moved to the right. Then, the hydraulic cylinder is turned on to move the curling block downward, and the edge of the cold-rolled plate can be quickly pressed downward. The first motor is turned on again to rotate the second roller in the opposite direction, and the cold-rolled plate is moved to the left, so that the edge of the first bent part is located below the curling block. The hydraulic cylinder is turned on to move the curling block downward, and the above steps are repeated to quickly curl the edge of the cold-rolled plate.

[0004] However, in actual use, the above-mentioned cold-rolled plate curling mechanism needs to repeatedly use the first motor, the second roller body and the curling block when the cold-rolled plate is curled, which reduces the curling rate of the cold-rolled plate. Therefore, the applicant proposes a cold-rolled plate curling mechanism. Utility Model Content

[0025] It should be noted that: when curling the cold-rolled plate, first, one end of the cold-rolled plate is clamped on the top of the block 208 through the transmission mechanism 3.
