Description

Composite wire rod hot straightening machine bearing cooling method Technical Field The invention relates to the field of composite wire hot straightening machines, in particular to a method for reducing the temperature of a bearing of a composite wire hot straightening machine. Background At present, when the composite hot wire material is subjected to hot rolling and then to a hot straightening process, the bearing in the straightener is particularly easy to damage, the bearing is rolled mainly during hot straightening, the temperature of the produced wire material is generally 300-500 ℃, and the temperature is generally about 500 ℃, and at the moment, the heat of 500 ℃ can be radiated to the machine body of the straightener. The general design of the straightening machine is that the two sides are provided with the racks, the middle is provided with the rollers, then the upper and lower rollers are adopted, the five-roller or seven-roller type thermal straightening machine is adopted, the design of the thermal straightening machine has the problems that the rollers are relatively short, the internal space of the thermal straightening machine is small, when wires pass through the thermal straightening machine, the space is particularly small, the temperature on the wires is generally more than 500 ℃, a large amount of heat can be conducted to the racks on the two sides, the racks on the two sides can conduct the heat into the bearings, so that lubricating oil carried in the bearings can be melted and evaporated quickly, then the bearings are in a dry grinding state, and the common bearings can not resist high temperature, and are particularly easy to damage due to the high temperature of 300-500 ℃.
