Discharging air cooling device and air cooling method for cold pilger mill

Abstract

The invention relates to the technical field of cold rolling machining, in particular to a discharging air cooling device for a cold pilger mill and an air cooling method. The device comprises a mounting plate, the upper surface of the mounting plate is fixedly connected with a cooling cylinder, the inner wall of the cooling cylinder is fixedly connected with two sealed bearing assemblies, the inner walls of the two sealed bearing assemblies are jointly and fixedly connected with a cooling pipe, the upper surface of the cooling cylinder is fixedly connected with an air pump and a driving mechanism, and the output end of the air pump fixedly communicates with a bent pipe. The bottom end of the bent pipe fixedly communicates with the outer wall of the cooling cylinder, and the outer wall of the side end of the cooling pipe is fixedly connected with a lubricating oil cleaning mechanism. Tubes output from the cold pilger mill are comprehensively and rapidly cooled through the cooling cylinder, the situation that the tubes deform in the transportation process after cold rolling is prevented as much as possible, the quality and the qualification rate of the tubes machined by the cold pilger mill are improved, lubricating oil on the surfaces of the cooled tubes is cleaned through the lubricating oil cleaning mechanism, manual operation is not needed, and the production efficiency is improved. The labor intensity of workers is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cold rolling processing, in particular to a discharge air cooling device and an air cooling method for a cold rolling pipe mill. Background technique [0002] With the rapid development of the national economy and the continuous expansion of new technology fields, the application range of cold-rolled pipes is becoming wider and wider, and the requirements for its variety and quality are getting higher and higher, especially in the development of industries such as aviation, rockets, automobiles, and shipbuilding. , so that the demand for various precision, thin-walled, high-strength cold-rolled pipes is increasing. At present, the production of these pipes is mainly cold-rolled pipe machines. [0003] Although the cold rolling process is carried out at room temperature, the extrusion and extension movements between the roll and the pipe will inevitably cause certain temperature fluctuations. At present, t...
