Abstract

The invention discloses a cold pilger mill capable of enabling rolling oil to be recycled conveniently. The cold pilger mill comprises a machine base and a machine shell on the machine base. One end of the machine shell is a feeding end, and the other end of the machine shell is a discharging end with a discharging opening. A roller feeding channel is horizontally arranged in the machine shell from the feeding end to the discharging end, and the position, where the roller feeding channel is placed, at the discharging end is provided with mill rolls in a pairing mode. The cold pilger mill capable of enabling the rolling oil to be recycled conveniently is characterized in that a rolling oil vacuum recycling device is further arranged outside the discharging opening on the machine shell. The cold pilger mill enables the rolling oil of the cold pilger mill to be recycled conveniently and has the advantages of being high in oil scraping efficiency and good in steel tube protective effect.

Description

technical field [0001] The invention relates to a cold-rolled pipe mill; in particular, it relates to a cold-rolled pipe mill which facilitates the recovery of rolling oil. Background technique [0002] The cold rolling mill is a process equipment for cold rolling the blank tube (that is, the billet tube) by using the annular hole shape. In the production of cold-rolled seamless stainless and high-alloy steel pipes, rolling lubricating oil must be applied to the blank pipes entering the rolls to facilitate the rolling and forming of steel pipes. This oil has a high viscosity and contains paraffin. Lubricating the tube billet and rolling mandrel during rolling can ensure the rolling quality of the steel pipe. [0003] When the billet tube is rolled into a finished tube, it reaches the material stand from the discharge port of the rolling mill with the advancement of the feeding device. During this period, the rolling oil sprayed on the surface of the pipe will slowly flow d...
