Rotatably-welding rivet and riveting method thereof

Abstract

The invention relates to a rotatably-welding rivet. The rivet comprises a rivet head, a rivet body and a rivet tail part. The rivet head and the rivet tail part are arranged at the two ends of the rivet body correspondingly and share the same axis with the rivet body. The bottom surface of the rivet head is provided with a material-storing groove. The material-storing groove is arranged on the rivet body in an encircling mode. The rivet is connected with a driving head of a special rivet installation device through the rivet head. The rivet installation device drives the rivet to rotate in a high speed through the rivet head. The rivet tail part is used for piercing a light metal plate and connected with the contacting area of a steel plate in a fused and welded mode. According to the rotatably-welding rivet, connection between the dissimilar metal plate and the steel plate is achieved, piercing the steel plate is not needed, the sealed waterproofing can be achieved, cutting is avoided in the riveting process, scrap materials are not generated, special heating treatment and surface treatment are not needed to be conducted on the rivet, and the cost is relatively low.

Description

technical field [0001] The invention relates to a connecting piece, in particular to a rotary welding rivet. Background technique [0002] In many installed equipment and equipment, it is necessary to install and fasten the thin-walled plates or related components to the design position, and to ensure the firmness of the installation. The usual method is to use riveting nuts to fasten the thin-walled plates or related components. Riveting with corresponding components, however, before riveting, holes must be pre-drilled at the riveting position so that the riveting nut can pass through the plate and related components for riveting. If no pre-drilling is made, riveting cannot be performed. [0003] When the thin-walled sheet or related components are made of lightweight metal plates, the pre-opening before riveting not only increases the production process and prolongs the production time, but also increases the risk of structural deformation of the thin-walled sheet or relat...

[0003] When the thin-walled sheet or related components are made of lightweight metal plates, the pre-opening before riveting not only increases the production process and prolongs the production time, but also increases the risk of structural deformation of the thin-walled sheet or related components; If the hole is pre-drilled, the seal cannot be guaranteed
