Telescopic type belt penetrating and oil spraying device

Abstract

The invention relates to a telescopic type belt penetrating and oil spraying device. A lower supporting oil-spraying plate is arranged below a rolling line, an upper stopping oil-spraying plate is arranged above the rolling line, oil spraying passages are respectively arranged on the lower supporting oil-spraying plate and the upper stopping oil-spraying plate, and one ends of the oil spraying passages, which are towards a roller system of an eighteen-roller rolling machine, are provided with spray heads; the two side edges of the lower supporting oil-spraying plate are respectively embedded in the guide grooves of the sliding guide rails of lower supporting plates at both sides, the sliding guide rails of the lower supporting plates are installed on a rack of the eighteen-roller rolling machine, and the lower supporting oil-spraying plate can freely slide in the guide grooves of the sliding guide rails of the lower supporting plates under the driving of the telescopic driving structures of the lower supporting plates; and the two side edges of the upper stopping oil-spraying plate are respectively embedded in the guide grooves of the regulating basal plates of upper stopping plates at both sides, and the upper stopping oil-spraying plate is installed on the rack of the eighteen-roller rolling machine. The telescopic type belt penetrating and oil spraying device has a reasonable structure, is convenient to use and can adapt to the requirements of belt penetrating of an eighteen-roller cold rolling machine and conveying of technological lubricating and cooling liquid, the auxiliary time of belt penetrating is greatly reduced, and the lubricating of a rolling process and the cooling of a rolling area are effectively improved.

Description

technical field [0001] The invention belongs to the technical field of cold rolling machinery and equipment, and in particular relates to a telescopic strip threading oil injection device on an eighteen-high high-precision strip cold rolling mill. Background technique [0002] The 18-high cold rolling mill has a tower-shaped arrangement of rolls and a compact structure. Although the diameter of the work rolls is (possibly) small, the work rolls still have a large With high strength and rigidity, it can roll metal strips of different materials, specifications or (and) different process states with large rolling force and high tension (cold) rolling. Especially in the field of rolling high-precision ultra-thin strips, the eighteen-high cold rolling mill has obvious advantages. [0003] The above-mentioned characteristics of the 18-high rolling mill also lead to the remote distance between the rolling area of ​​the rolling mill and the side of the rolling mill archway (inlet a...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned characteristics of the 18-high rolling mill also lead to the remote distance between the rolling area of ​​the rolling mill and the side of the rolling mill archway (inlet and outlet surface), which in turn causes problems such as difficulty in strip threading of the rolling mill and poor process lubrication and cooling
