Description

Technical Field

[0001] The utility model relates to the field of steel plate processing equipment, in particular to a steel coil leveling device. Background Art

[0002] In the field of sheet metal processing, the transportation and storage of sheet metal raw materials have always been a key link. Considering the maximization of efficiency and space utilization, the form of steel coils has become the most ideal choice, especially when large quantities of steel plates need to be processed, the advantages of steel coils are particularly prominent. By rolling into a tight circle, it can not only save a lot of storage space, but also facilitate handling and stacking, greatly reducing the cost and risk during transportation and storage.

[0003] When using steel coils, the rolled steel plates need to be unfolded first and then cut into plates of the required length. During this process, the steel coils will bend to a certain extent due to being stored in coils for a long time, so the steel coils need to be leveled, which is usually achieved through a hydraulic uncoiler combined with leveling machines of different specifications.

[0004] The leveler is the main equipment for leveling the steel plate after the steel coil is uncoiled. The working part of the leveler is usually a horizontally arranged roller and pressure roller structure. The head of the steel coil enters between the roller and the pressure roller, and then with the conveyance of the uncoiler, the steel plate passes between the roller and the pressure roller. In this process, the squeezing effect of the roller and the pressure roller restores the steel plate to a straight state. After leveling, the steel coil is cut into plates of the required size.

[0005] However, for coils with thicker thickness (≥3mm) and higher hardness, the material head will be curled up due to stress deformation after unwinding, making it difficult to enter the leveling machine for leveling. Utility Model Content

[0009] Preferably, the first flipping drive mechanism comprises a first hydraulic cylinder, both ends of which are respectively hinged to the frame and the supporting assembly; the second flipping drive mechanism comprises a second hydraulic cylinder, both ends of which are respectively hinged to the frame and the conveying assembly.

[0010] Preferably, the conveying assembly includes a pressing arm, which is a frame structure. The rear edge of the pressing arm is hinged to the frame. The first flipping drive mechanism is provided with two groups and is respectively connected to the two sides of the pressing arm. The friction drive member is installed at the front end bottom of the pressing arm.

[0011] Preferably, the friction driving member is a friction roller, and the conveying assembly further comprises a driving motor for driving the friction roller to rotate.

[0012] Preferably, the conveying assembly further comprises a pressing plate mechanism, which comprises a pressing condition and a third hydraulic cylinder, wherein the end of the telescopic rod of the third hydraulic cylinder is fixedly connected to the pressing condition, and the pressing condition faces the supporting assembly.
