Spin riveting is a kind of riveting methods

in which the rivet shaft presses the local of rivet

and swings continuously around a central pivot until rivet shaped. After forming

the rivet material is continuous without breaking

bending

bulging

and the parts connected with the rivet are not deformed. In the 2017 materials as the object of ϕ6 rivets

based on Simufact. Forming software

using the method of tracking its spin riveting and the numerical simulation on forming process

extracting the stress values of rivets during certain points of the deformation zone

and the data is transformed to the equivalent stress-travel curve

then explore deformation mechanism of spin riveting. According to the structure of the wind panel and its assembly process

the deformation mechanism of the spiral riveting is applied to the rotary riveting equipment. By optimizing the structure of the riveting equipment

the CNC technology is introduced into the equipment to realize automatic processing and improve the efficiency and quality of wall panel processing.
