The winding drum of the hot rolling coiler is a key part of a hot rolling strip steel production line. The strip needs to be coiled into a steel coil after being rolled, so that the strip is convenient to store, and once expansion and contraction are needed when a coil of strip steel is coiled by a winding drum. Four symmetrical inclined planes are arranged on the peripheral surface of a mandrel of the hot-rolling winding drum, a plunger piston body is arranged between the mandrel and the sector plate, and the plunger piston body is a solid cylinder which is integrally cast by copper and has an inclined plane at the bottom surface. The top surface of the plunger body is supported on the bottom surface of the sector plate, the bottom surface of the plunger body is supported on the inclined surface of the mandrel, and springs pressed by the pressing plates are radially arranged at two ends of the sector plate. When the mandrel moves relative to the plunger body toward the top of the inclined surface thereof, the plunger body moves radially outward along the hot-rolled coil against the sector plate, causing the hot-rolled coil to expand in diameter. During the process of expanding or reducing the diameter of the hot-rolled winding drum, all matching surfaces need to slide relatively, the sliding is promoted by filling lubricating grease in the prior art, and if the lubricating grease is not filled in place, the matching surfaces can be quickly worn. The existing hot-rolled winding drum structure in China is basically mature and shaped, but the existing lubricating grease lubricating process has more problems, is the most common reason for the failure of the winding drum, and mainly comprises the following steps: the lubricating grease is easy to cause oil circuit blockage due to carbonization in a high-temperature environment, and the oil circuit in the winding drum is complex and needs higher transmission pressure, so that oil leakage accidents are easy to happen. The existing domestic hot-rolled winding drum needs to be taken off the machine for replacing an oil way system after being basically used on line for about one year, and various problems caused by oil way faults can also cause the winding drum to be taken off the machine for maintenance in advance.
