Cold-rolled steel pipe outer surface oil removal device and cold-rolled steel pipe production system

Abstract

The invention belongs to the technical field of cold-rolled steel pipes, and discloses a cold-rolled steel pipe outer surface oil removal device. The cold-rolled steel pipe outer surface oil removal device comprises a support, a thread rope and a power assembly, the steel pipe penetrates through the support, the power assembly is arranged on the support, the thread rope is driven by the power assembly to rotate around the steel pipe, and the thread rope is attached to the steel pipe by at least a circle; and oil on the surface of the steel pipe is removed along with the relative movement between the steel pipe and the thread rope. The invention further discloses a cold-rolled steel pipe production system. The cold-rolled steel pipe production system comprises a cold-rolled steel pipe machine, the above cold-rolled steel pipe outer surface oil removal device and an oil receiving disc; the steel pipe discharged from the cold-rolled steel pipe machine enters the cold-rolled steel pipe outer surface oil removal device, then the oil on the outer surface of the steel pipe is removed, and the oil is collected by the oil receiving disc. The cold-rolled steel pipe outer surface oil removaldevice and the cold-rolled steel pipe production system are reasonable in structural design, low in manufacturing cost and small in occupied area, and can be suitable for the steel pipes with different diameters without replacing parts.

Description

technical field [0001] The invention belongs to the technical field of cold-rolled steel pipes, and particularly relates to a cold-rolled steel pipe outer surface degreasing device and a cold-rolled steel pipe production system. Background technique [0002] A large amount of lubricating oil is attached to the surface of the cold-rolled steel pipe produced by the cold-rolled steel pipe machine. If it is not treated and recycled, it will cause waste of lubricating oil on the one hand, and oil pollution during transportation will also cause oil pollution, so a suitable method is needed. Remove lubricating oil from the surface of cold-rolled steel pipes. The traditional method is to make the receiving rack with a certain slope, and place the oil receiving pan under the receiving rack. After the finished steel pipe is rolled, it is collected on the receiving rack. Due to the inclination, the lubricating oil on the surface flows down along the inclination and drips into the oil ...

AI Technical Summary

Problems solved by technology

Due to the processing accuracy of the steel pipe and the force of the rubber sleeve holding the steel pipe are not easy to control, it is easy to cause a certain gap between the rubber sleeve and the outer wall of the steel pipe, resulting in poor degreasing effect and prone to leakage or locking

[0004] The existing degreasing technology does not remove the oil thoroughly, and the degreasing time is long, and the structure of the degreasing device is complicated, and the cost is high. For example, the slope of the material rack is used to remove the lubricating oil on the surface. The biggest disadvantage of this method is that the degreasing time is too long , and because the lubricating oil has a certain degree of adsorption, the removal of the lubricating oil on the surface will be incomplete only by the slope of the material rack; the structure of using the rubber sleeve to hold the steel pipe to remove the lubricating oil on the surface is the biggest disadvantage of this method. The sleeve may not be in full contact with the steel pipe, and there may be a phenomenon of missing scraping, and it is necessary to replace the rubber ferrule of different sizes and diameters for steel pipes of different diameters
