Rivet riveting has the advantages of simple process equipment, shock resistance, impact resistance, uniform force transmission, firmness and reliability, etc. The key parts of mining equipment such as skips, cages, dumpers, and mine trucks are all connected by rivet riveting. The quality of rivet riveting directly affects the product quality, working performance and service life of mining equipment. The number of rivets used in mining equipment is huge. Each mining equipment requires one hundred or hundreds of rivets, and they are used in mining equipment. The specifications of the rivets in the equipment are large, and the riveting process of hot riveting is mostly used. The riveting tools required are riveting machines and rivet molds.
At present, most of the thread locking structures use an integral nut and a matching external thread screw structure. To remove the nut from the screw rod, it must be completely unscrewed along the screw rod, which is time-consuming and labor-intensive. It is more inconvenient to install.
The existing structure is found in the practical application experience that there are still the following problems and drawbacks: the screw structure and the screw space are combined with each other in a complementary manner, so they can provide a higher torque value, however, not every workpiece. The combination requires a high torque value, so it often results in excess quality. Although the price of the screw is low, if it can change the unchanging structure of the traditional screw, it can provide a technical means to simplify (change) the process. The effect of improving production capacity and convenience of use is indeed a technical bottleneck that the relevant industry should break through.
According to the process, the wing nut can be divided into cold heading wing nut, casting wing nut and stamping wing nut. According to the shape, it can be divided into two basic shapes: square wing and round wing. According to the national standard number, it can be divided into GB/T62.2-2004 Square Wing Wing Nut Wing Nut Round Wing Wing Nut Round Wing GB/T62.1-2004 Round Wing Wing Nut
