Improvement of operating efficiency of small and medium-sized industrial precision wire rolling mills

The wire rolling mill is similar to the conventional strip rolling mill, and the purpose is to obtain the required rolling stock size through precision rolling mill rolling. In the operation of wire rolling mills, in order to improve the operation efficiency, it is necessary to carry out corresponding improvement measures. The material of the roll should be screened according to the requirements of the rolling piece to improve the fatigue strength and service life of the roll, and the wear of the roll and guide should be checked from time to time.

Reverse the injection process of bearing lubricating oil – from the original internal – external to external – internal, so as to reduce the pollution of dust to the bearing. The cold rolling mill uses ultrasonic technology to inspect and analyze the rolls; the dry lubricating oil point has been modified, and the current dry oil is added from the high pressure area, and the amount added is increased from every six cycles of the raw material to eleven times, and the thin oil lubrication is 15 minutes a cycle.

The application of oil and gas lubrication to the roller bearings of wire rolling mill machine can greatly improve the lubrication condition and greatly increase the service life of the bearings; it improves the oil stains in the roller bearing seat when dry oil lubrication is used, which is difficult to clean, and the bearing seat becomes It is relatively clean and greatly reduces the labor intensity of maintenance workers.

The compressed air that continuously enters the bearing seat can cool the bearing; avoid the pollution of cooling water or emulsion caused by the leakage of grease from the bearing seat and the black spot formed on the surface of the steel plate when the flat wire rolling machine uses dry oil lubrication , reducing the cost of water treatment and prolonging the replacement cycle of the emulsion.

In order to prolong the service life of the wedge wire rolling mill machine roll bearing, the profile wire rolling machine adopts the correct lubrication method besides sealing the roll bearing. Oil-air lubrication can use high-viscosity lubricating oil, so as to control the working condition of the lubrication system, improve the sealing performance of the shaped wire rolling machine bearing seat, and reduce the temperature of the roll bearing during friction.
