Abstract

The invention discloses a fluid shearing type metal parts surface derusting device, which belongs to the technical field of metal derusting. The bubbles are continuously introduced into the fluid shearing and derusting cylinder to achieve high-speed shearing of the fluid through the dense shunting screen, and at the same time drive some magnetic impurity spheres to drive upwards to drive the impact, floating in the magnetic field of the fluid shearing and derusting cylinder. The impurity balls capture the air bubbles in the water body, and after colliding with the metal parts, the air bubbles are compressed to generate impact force, destroying the rust and oxidized impurities on the metal surface, and the magnetic flotation derusting mechanism has a certain magnetic attraction effect, which is good for floating The magnetic impurity spheroids have the function of magnetotropic movement, which further increases the contact and collision probability between some magnetic impurity spheroids and metal parts, and is easy to carry out surface treatment on metal parts with smaller specifications.

Description

technical field

[0001] The invention relates to the technical field of metal rust removal, in particular to a fluid shear type metal parts surface rust removal device. Background technique

[0002] At present, in the production process of metal parts, it is necessary to derust and polish the end faces of the parts to facilitate the later painting and coating treatment. The derusting process is one of the essential processes in the production process.

[0003] In addition, during the use of metal parts, due to climate and working conditions, etc., corrosion will occur, which will affect the use, especially for bearings and protective end covers in the transmission structure, which will affect the smoothness of power transmission after corrosion and are prone to corrosion. Stuck. Therefore, it is necessary to disassemble and replace new bearings, but for rusted bearings, after removing the surface rust, they are used in transmission positions with poor precision requirements ...
