Description

Technical Field

[0001] The utility model relates to the technical field of metal plate calendering, and more specifically to a roller adjusting mechanism of a metal plate calender. Background Art

[0002] Metal rolling processing is a process that applies pressure to metal to stretch it into a certain shape based on its ductile nature. It is a device that produces thicker hot-rolled steel strips into thinner cold-rolled steel strips.

[0003] After searching, the utility model patent with announcement number CN219378434U discloses a roller adjustment mechanism for a metal sheet calender, including a first roller, a second roller and a lifting mechanism; the first roller is arranged above the second roller, and the left and right ends of the first roller and the second roller are connected to the calender frame through connecting roller shafts; the connecting roller shafts at the left and right ends of the first roller are rotatably connected with lifting cylinders, the top of the lifting cylinder is fixedly connected with a lifting slide bar, the upper part of the lifting slide bar is sleeved with a fixed cylinder, and the fixed cylinder is fixed on the left and right sides of the calender frame; the lifting mechanism includes a lifting frame, the bottom of the lifting frame is movably connected with the lifting slide bar, the top of the lifting frame is provided with a horizontal driving frame, and the bottom of the horizontal driving frame is connected with a lifting device; this patent fixes both sides of the rollers of the calender on the same lifting component, and by adjusting the height of the lifting frame, the two sides of the rollers are lifted and lowered synchronously, thereby realizing accurate and rapid adjustment of the spacing between the rollers.

[0004] However, the above patent still has the following shortcomings: a hydraulic rod is used to drive the lifting frame and the horizontal driving frame to move up and down, thereby driving the first roller to move up and down, avoiding the height inconsistency on both sides caused by the two hydraulic rods. When the first roller is used to roll the metal plate, it will be subjected to reverse extrusion force, which is easy to cause the lifting frame and the horizontal driving frame to deform, and still cannot completely avoid the first roller from tilting; in addition, when the first roller rolls the metal plate, the effect of pushing the first roller downward by the lifting and lowering slide bars on both sides is not good, and there is uneven extrusion force in the middle of the first roller. For this reason, we propose a roller adjustment mechanism for a metal plate rolling machine. Utility Model Content
