Automatic cooling device for pipe cold-rolling mill

Abstract

The invention discloses an automatic cooling device for a pipe cold-rolling mill. The automatic cooling device comprises an electromotor, an air bellow and an air blower; the electromotor is fixedly installed in the air bellow through a supporting frame, an air outlet is formed in one side of the bottom of the air bellow, and a temperature sensor is arranged on the surface of the electromotor; an air guide pipeline fixedly installed is arranged on one side of the top of the air bellow, the other end of the air guide pipeline is connected to the air blower through bolts, the top of the air blower is connected to a microprocessor, and an air inlet is formed in one side of the air blower; a dust prevention device is arranged between the air blower and the air inlet and comprises a dust prevention cover and an air inlet frame, and the air inlet frame is fixedly connected to the air inlet. The automatic cooling device is simple in structure; by turning on or turning off the air blower through the microprocessor, the electromotor can be automatically cooled in time, and the electric energy can be saved; by installing the electromotor inside the air bellow, the electromotor can be cooled uniformly and continuously; the cost is low, and realization is easy.

Description

Technical field [0001] The invention relates to a cold-rolling pipe mill cooling equipment, in particular to an automatic cooling device for a cold-rolling pipe mill, belonging to the technical field of steel pipe manufacturing. Background technique [0002] When making steel pipes, the steel pipes are cold rolled by using the ring hole shape of the cold-rolling pipe mill. The cold-rolling pipe mill has better billeting performance, high material utilization, and the accuracy and surface roughness are better than cold drawn pipes , The use of metal elastic deformation to achieve steel pipe rolling. [0003] In the working process, the motor of the cold rolling tube mill has a heavy workload and the temperature rises rapidly. If it is not cooled, the service life of the motor will be shortened, and the maintenance cost will be high, which will affect the work process. At present, although there are also It cools down, but the air sent by the blower into the main motor is often mixe...

AI Technical Summary

Problems solved by technology

[0003] During the working process, the motor of the cold rolling mill has a heavy workload and the temperature rises rapidly. If it is not cooled, the service life of the motor will be shortened, and the maintenance cost will be high, which will affect the work process. It cools down, but the wind sent by the blower to the main motor is often mixed with some dust and impurities, which will also affect the service life of the main motor and is not easy to clean. Improper placement makes the motor cooling effect not obvious

The temperature on one side of the motor principle induced air duct still cannot be properly handled
