Description

Combined type roller

Technical Field

The invention relates to the technical field of machining equipment, in particular to a combined type roll shaft.

Background

The roll shaft is also called as a roller and refers to a general name of a cylindrical machine part capable of rolling on a machine. The roller is in actual use operation in-process, receives the influence of factors such as the metal property and the relatively poor, the big shortcoming of neck size appear in operation of bearing impact resistance, often causes the axle wearing and tearing to the roller vibrations that appear increase causes the noise grow, vibrations, circumstances such as unstability. When the pressure is more serious, the shaft head can be broken, other parts such as equipment and the like can be damaged, major accidents can be caused, and the normal production of enterprises can be seriously influenced. The traditional repair welding repair method is easy to cause material damage, causes part deformation or fracture and has larger limitation; the methods of brush plating and spraying re-machining usually need external cooperation, so that the repair cycle is long, the cost is high, and the reason for abrasion (poor metal impact resistance and deformability) cannot be fundamentally solved because the repaired material is still a metal material; and a plurality of parts can only be replaced by scrapping, so that the production cost and the stock spare parts are greatly increased, and good resource advantages of enterprises are idle and wasted. The existing roll shaft is too long in length, and under the condition of high temperature, the asbestos fiber layer is burst due to thermal expansion, so that the field use is affected. In addition, the bottom roller of the heat-resistant steel furnace can generate nodules, the surface of the steel plate can generate roll marks, and the furnace is required to be run once every five days, and at least four to five times a month. The furnace needs to be stopped for 3-5 days in half a month, furnace bottom rollers are polished, product quality objections often appear, the delivery period is influenced, the steel plate needs to be degraded for use, and the price per ton is reduced by 500 yuan.
