A kind of antirust method for box opening sealing

Abstract

The invention belongs to the technical field of sealing and rust prevention, and particularly relates to a box body orifice sealing rust prevention method. The sealing rust prevention method comprisesthe following steps that an electric brush is used for grinding the surface layer of a hole opening of the box body, and a corrosion layer on the surface layer of the hole of the box body is removed;the hole of the box body is cleaned, wiped and dried; rust-proof oil is uniformly coated at the hole opening of the box body, and preliminary rust-proof treatment is performed on the hole opening ofthe box body, so that the sealing performance of the hole opening of the box body is influenced due to the fact that the hole of the box body is rusted; a sealing shell is attached to the hole openingof the box body, and a self-locking type core pulling rivet is fixed on the rivet hole through a pulling and riveting gun, so that the sealing shell and the box body are fastened permanently; and thesealing part and the rivet hole are filled with sealant, paint spraying treatment is carried out on the edge of the sealing shell and the self-locking type core-pulling rivet, and sealing and rust-proof treatment on the hole opening of the box body is completed. The sealing shell is fastened on the box body through the self-locking type core pulling rivet, so that the sealing performance of the hole opening of the box body is improved.

Description

technical field [0001] The invention belongs to the technical field of sealing and antirust, in particular to a method for sealing and antirusting an orifice of a box body. Background technique [0002] In many box-like components with an inner cavity structure, the parts in the box are connected to the outside of the box through the opening of the box. The inside of the box needs to prevent external impurities such as dust and moisture from invading the inside of the machine and equipment to avoid The material or parts of the internal parts are damaged to affect its performance. However, the orifice of the box is easily corroded by the acid, alkali and salt of the outside at room temperature and rusts. It has airtightness, so while the box is sealed, it is also necessary to carry out anti-rust treatment on the opening of the box to ensure that the inside of the box is in a closed state, and to ensure that the outside water vapor and dust are separated from the inside of the...

[0002] In many box-like components with an inner cavity structure, the parts in the box are connected to the outside of the box through the opening of the box. The inside of the box needs to prevent external impurities such as dust and moisture from invading the inside of the machine and equipment to avoid The material or parts of the internal parts are damaged to affect its performance. However, the orifice of the box is easily corroded by the acid, alkali and salt of the outside at room temperature and rusts. It has airtightness, so while sealing the box body, it is also necessary to carry out anti-rust treatment on the opening of the box body to ensure that the inside of the box body is in a closed state, and to ensure that the outside water vapor and dust are separated from the inside of the box body

[0003] The common method is to add a sealing shell to the opening of the box body, and use the sealing shell to seal the opening of the box body, but it is inconvenient to use ordinary rivets for many boxes, that is, it is inconvenient to use ordinary rivets for riveting occasions that must be riveted from both sides, but automobiles, ships , airplanes, machines, electrical appliances and other heavy box products often have some connection occasions with high load and certain sealing performance, so suitable fasteners need to be selected well; at the same time, some fasteners are used in fastening products There will be rebound or looseness after the fastener, and the rebound and looseness of the fastener will destroy the protective layer on the surface of the fastener, so that the fastened product cannot be protected by the protective layer
