Benefits of technology
The present invention provides a method of riveting a sheet of metal using a special tool. The method allows for a sufficient deformation of the metal sheet at the internal edge of the rivet hole, ensuring the rivet member is securely fastened. The technical effect of the invention is to provide a reliable and efficient method for riveting metal sheets.
Problems solved by technology
However, the conventional riveting technology is not suitable to be applied to a thin sheet.
Because there is no enough thickness defined on the vertical direction of the thin sheet for the purpose of being pressed, so that a sufficient deformation in the horizontal direction for allowing the rivet member to embed cannot be formed with the deformation in the vertical direction, thereby causing the rivet member unable to be stably fastened on the thin sheet.

Abstract
A method of riveting sheet includes the following steps: providing a metal sheet, a rivet member and a tool of riveting sheet, an engaging structure is formed at an external edge of the rivet member, the tool includes a first riveting head and a second riveting head, and a rib is formed on a surface of the first riveting head; defining a rivet hole on the metal sheet; disposing the rivet member in the rivet hole and arranging the engaging structure corresponding to an internal edge of the rivet hole; clamping the rivet member by the first riveting head and the second riveting head and pressing both surfaces of the metal sheet, the rib is therefore embedded into the metal sheet to deform the metal sheet and the internal edge of the rivet hole is shrunk to embed into the engaging structure.
Description
BACKGROUND OF THE INVENTIONField of the Invention[0001]The present invention relates to a riveting technology, especially to a method, a structure and a tool of riveting sheet.Description of Related Art[0002]A riveting operation is used for connecting two metal members, the theory is that at least one of the metal members is pressed for generating a deformation, and the deformed portion thereof is mutually embedded into the other metal member for enabling the two metal members to be connected and fastened. As such, a rivet member, for example a screw nut or a riveting nail, is often adopted in the riveting technology for being fastened on a metal sheet.[0003]Generally speaking, a hole is firstly formed on a metal sheet for allowing a rivet member to be disposed therein, then a tool is utilized for pressing two surfaces of the metal sheet along the vertical direction of the metal sheet, so that a deformation in the horizontal direction is formed on the metal sheet, and an internal ed...
