The invention discloses replacement-free self-feeding rust removal equipment for a cold rolling mill. The replacement-free self-feeding rust removal equipment for the cold rolling mill comprises a fixing seat, wherein a plurality of supporting pieces are arranged in the fixing seat, a plurality of groups of grinding mechanisms are arranged in the fixing seat, each group of the grinding mechanisms comprises a first gear, an outer gear ring and a plurality of second gears, and each first gear and the plurality of second gears are engaged with the corresponding outer gear ring separately; and a rust removal device is installed on the inner side wall of each outer gear ring. The replacement-free self-feeding rust removal equipment for the cold rolling mill can carry out all-directional grinding and rust removal on pipes, meanwhile, a grinding pressure is kept stable, the specifications of ground parts do not need to be replaced, and the replacement-free self-feeding rust removal equipment for the cold rolling mill is suitable for rust removal operation for the pipes with different diameters.
Description
technical field [0001] The invention relates to the technical field of cold rolling mills, in particular to a replacement-free self-feeding derusting equipment for cold rolling mills. Background technique [0002] Compared with the hot rolling mill, the cold rolling mill has the advantages of good surface quality, precise size, etc., as well as fast forming speed and high output. Therefore, the cold rolling mill also has a wide range of applications. The cold rolling mill can not only be used to process plates, It can also be used to process pipes. [0003] The cold-rolling mill for processing pipes is also called cold-rolling pipe mill, which is implemented by cold-rolling the pipes with ring holes, because the pipes are mostly stacked outdoors before processing, and the surface is prone to rust, while the surface of the pipes Rust will lead to differences in the strength and thickness of the pipe wall, which will affect the cold rolling result. Therefore, the pipe needs t...
