Rolling wheel of flange ring rolling mill

一种法兰环轧机上的碾压轮

Abstract

The utility model discloses a rolling wheel of a flange ring rolling mill. The rolling wheel comprises a rolling wheel body and a rolling wheel end cover, wherein the rolling wheel end cover is assembled on the rolling wheel body; an abrasion-resistant sleeve is sleeved on the surface at the middle section on the circumference of the rolling wheel body. Because the rolling wheel comprises the rolling wheel body and the rolling wheel end cover, the rolling wheel end cover is a shared body of all dies; different rolling wheels can be formed by change of the specifications of the rolling wheel body so as to adapt to the processing of flange blank pieces with various specifications and consequently the storage space of the rolling wheel is reduced. As the easily-abraded part in the rolling wheel is the rolling wheel body or the rolling wheel end cover and only the part in the rolling wheel needs to replace in the replacement of the rolling wheel, the die cost is reduced greatly. When the rolling wheel generates a defect and needs to repair, only the part generating the defect needs to repair and the part is smaller in volume and lighter in weight than the rolling wheel whole body, thus being convenient to repair; and the rolling wheel is small in occupied storage space, low in cost and convenient to repair.
本实用新型公开了一种法兰环轧机上的碾压轮,该碾压轮包括有碾压轮本体和碾压轮端盖,碾压轮端盖装配在碾压轮本体上,在碾压轮本体圆周中间段的表面套装有耐磨套;由于将碾压轮分解为碾压轮本体和碾压轮端盖两部分,碾压轮端盖是所有模具的共用体,通过改变碾压轮本体的规格,可构成不同的碾压轮以适应繁多规格法兰坯件加工,这样能减小了碾压轮的存放空间。由于碾压轮中易磨损的部件为碾压轮本体或碾压轮端盖,更换碾压轮只需更换碾压轮的部件,大大降低了模具的成本。当碾压轮有缺陷需要维修时,只需拿有缺陷的部件去维修,该部件与碾压轮整体相比体积小、重量轻,方便修理,存放空间占用小,成本低,维修方便。
