FRAME FOR SELF-PIERCING RIVET SYSTEM

摘要

A frame for a self-piercing rivet system that can provide bearing capacity for joining a rivet to a plate by using an anvil die and a punch unit is disclosed. An exemplary embodiment of the present invention provides a frame for a self-piercing rivet system provided with a punch unit on an upper portion thereof and an anvil unit on a lower portion thereof corresponding to the punch unit, that may include: an outer frame portion formed by connecting an inner semicircular body and an outer semicircular body which has a different radius and a central position from the inner semicircular body by a plurality of ribs; an inner frame portion formed by connecting both ends of a bending body to both ends of the inner semicircular body at the inside of the outer frame portion; an upper inner extender extended from an upper end of the inner frame portion; an upper outer extender extended from an upper end of the outer frame portion; a lower inner extender extended from a lower end of the inner frame portion; a lower outer extender extended from a lower end of the outer frame portion; a punch mounting end integrally formed at a front end of the upper inner extender and the upper outer extender; and an anvil mounting end integrally formed at a front end of the lower inner extender and the lower outer extender.
