Description

Technical field [0001] The invention relates to the field of spin riveting mechanical devices, in particular to a spin riveting die and a spin riveting operation process on a spin riveting machine, and in particular provides a new high-precision riveting mechanical device. Background technique [0002] The existing riveting device mainly uses the knocking method to produce plastic deformation at the end of the rivet. The disadvantage of this riveting method is that it is difficult to control the deformation of the end of the rivet, resulting in uneven deformation. In addition, the load on the rivet is uneven. Therefore, it is easy to cause stress concentration, resulting in unreliable fastening, inconvenient operation, laborious manual operation, high labor intensity, industrialization, and low efficiency. Therefore, the use of spin riveting machines for riveting is now beginning to appear. , But when the current spin riveting machine installs the spin riveting die on the spin ri...

Problems solved by technology

[0002] Existing riveting devices mainly use the way of knocking to make the end of the rivet plastically deformed. The defect of this riveting method is that it is difficult to control the deformation of the end of the rivet, resulting in uneven deformation. In addition, due to the uneven load on the rivet Therefore, it is easy to cause stress concentration, resulting in unreliable fastening, and it is inconvenient to operate, manual operation is laborious, labor-intensive, and industrialization cannot be formed, and the efficiency is low. Therefore, the use of riveting machines for riveting is now appearing , but when the current riveting machine installs the riveting die on the riveting machine, the forming cavity of the riveting die is spherical. When the upper die acts on the rivet, it is easy to cause the rivet to shift, so that the end of the rivet is at the same The deformation on the circumference is inconsistent, causing stress concentration and reducing the fastening strength of the rivet. Therefore, it is necessary to provide a spin riveting device with non-concentrated stress, uniform deformation, reliable fastening and high efficiency.
