Machining 304 stainless steel

rivet nut is a tool for riveting nuts, which can be used for riveting the nut to a sheet and has a wide range of uses. Most of the existing rivet nuts have a double-handled structure, which is complicated in structure and high in cost; and the double-handled structure generally requires both hands to operate due to the large distance between the two handles, which is inconvenient to operate. Technical realization elements: In order to solve the above technical problems, Yueluo provides a rivet nut with simple structure, low cost and convenient operation. The technical solution adopted by Yueluo is: including a fixed body, a sliding body, a guide sleeve, a nut, a hollow screw and a handle;

screw with a gasket aims to provide a screw with a gasket that improves installation efficiency. The technical solution of the screw is that after the screw cap, the connecting rod and the screw rod are processed, the gasket with the installation through hole is processed. The installation through hole is drilled through the connecting rod, and then the end of the screw rod opposite to the connecting rod is processed to form a convex tooth structure by extrusion. At the same time, the outer diameter of the tooth peak of the convex tooth is larger than the inner diameter of the installation through hole, so that the gasket is not easy to be installed. Falling off, the step of manually wearing the gasket is reduced, that is, the workload of the staff is reduced, and the installation efficiency is relatively high. The flange increases the contact area between the screw cap and the gasket, and enhances the friction between the screw cap and the gasket, which can prevent the screw from loosening easily after being fastened and installed, thereby improving the connection stability of the screw. When installing the screw, the fixing part can be snapped into the fixing groove on the installation plane, so as to avoid the washer from rotating with the rotation of the screw when the screw is tightened, which is convenient for the tightening and installation of the screw.


At present, the installation methods of the retaining ring: 1. Most of them are installed with retaining ring installation pliers; 2. Simple installation aids; 3. Automatic retaining ring installation machine. The disadvantages of these installation methods: 1. If the manual installation is uneven, the elastic retaining ring will deform plastically, which will cause the elastic retaining ring to fail; 2. It cannot be positioned for complex structural parts, and the production efficiency is also low; 3. Simple installation Auxiliary tools are only suitable for the parts to be installed, which are generally not universal and have limitations; 4. The automatic elastic retaining ring installation machine has a complex structure and high cost.
