Description

Technical Field

[0001] The utility model relates to the technical field of magnets, and more particularly to a stainless steel integrally coated magnet. Background Art

[0002] Magnets are composed of atoms such as iron, cobalt, and nickel. Their unique internal structure gives them an inherent magnetic moment. This allows them to generate a magnetic field, attracting ferromagnetic materials like iron, nickel, and cobalt.

[0003] At present, magnets are often used as adsorption parts in the industrial field. They are coated with a base to grab and move workpieces. However, most of the existing coated magnets are usually glued to the base with glue. After repeated use, the glue adhesion is easy to fall off, which shortens the service life of the magnet. In order to facilitate the adsorption of workpieces, the adsorption surface of the magnet is flush with the base. Since the magnet is not completely coated and exposed on the surface, it has no impact resistance, and the surface coating of the magnet is prone to powdering. The base is generally made of steel and iron, which is not only prone to rust, but also easy to spread the magnetic force. The outer wall of the base also has a certain degree of magnetism, and the axial magnetic force is relatively weak. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] In response to the problems existing in the prior art, the purpose of the present utility model is to provide a stainless steel one-piece coated magnet, aiming to solve the problem that most of the coated magnets in the prior art are usually glued to the base with glue. After repeated use, the glue adhesion is easy to fall off, which shortens the service life of the magnet. In order to facilitate the adsorption of workpieces, the adsorption surface of the magnet is flush with the base. Since the magnet is not completely coated and exposed on the surface without impact resistance, the surface coating of the magnet is prone to powdering. The base is generally made of steel and iron, which is not only prone to rust, but also easy to spread the magnetic force. The outer wall of the base will also have a certain degree of magnetism, and the axial magnetic force is relatively weak.

[0006] 2. Technical solution

[0007] In order to solve the above problems, the present invention adopts the following technical solutions:

[0008] A stainless steel integrally coated magnet includes a stainless steel base, a mounting groove is opened at the top of the stainless steel base, a copper ring and a magnet body are fixedly connected in the mounting groove, and the magnet body is located in the copper ring, and a stainless steel plug cover is fixedly connected to the top opening of the mounting groove, and the stainless steel plug cover is located on the upper side of the copper ring and the magnet body.

[0009] As a preferred solution of the present invention, a connecting hole is provided at the bottom end of the stainless steel base, and the connecting hole is communicated with the mounting groove.

[0010] As a preferred solution of the present invention, the stainless steel plugging cover is fixedly connected to the mounting groove by laser welding, and the welding point between the stainless steel plugging cover and the mounting groove is ground and polished.

[0011] As a preferred solution of the present invention, the top of the stainless steel cover and the top of the stainless steel base are in the same horizontal plane.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] (1) In this solution, the copper ring and the magnet body are installed in the installation groove opened in the stainless steel base, and are welded and sealed with a stainless steel plugging cover, which can effectively prevent the magnet body from falling off after repeated use, thereby improving the service life of the coated magnet. The stainless steel base and the stainless steel plugging cover fully cover the magnet body, making the coated magnet resistant to impact, preventing the magnet body from being exposed and damaged, and further improving the service life.

[0015] (2) In this solution, the stainless steel base and the stainless steel plug cover are both made of stainless steel, which has good salt spray resistance and does not require surface treatment, effectively preventing rust.

[0016] (3) In this solution, the magnet body is located on the inner side of the copper ring. The copper ring blocks the diffusion of the lateral magnetic force and concentrates the magnetic force in the axial direction, thereby reducing the magnetism of the outer surface of the stainless steel base. After the axial magnetic force is concentrated, the magnetic force is stronger, thereby improving the adsorption effect on the workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
