Rotatably-welding rivet and riveting method thereof

Abstract

The invention relates to a rotary welding rivet, which comprises a rivet cap, a rivet body, and a rivet tail; the rivet cap and the rivet tail are respectively arranged at two ends of the rivet body, and are coaxial with the rivet body; the rivet cap The bottom surface is equipped with a material tank, which is set around the rivet body; the rivet is connected to the drive head of the specific rivet installation equipment through the rivet cap; the rivet installation device drives the rivet to rotate at high speed through the rivet cap; Wear lightweight metal plates and join them by fusion welding together with the contact areas of the steel plates. The invention realizes the connection of dissimilar metal plates and steel plates without piercing the steel plates, can realize sealing and waterproof, and there is no cutting in the riveting process, and no waste is produced; the rivets do not need special heat treatment and surface treatment, 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
