Device for caulking fastening element in through hole of plate, has extrusion die acting on flange and support claw which engages on plate during pressing process

摘要

#CMT# #/CMT# The device has an extrusion die (51) acting on a flange and a support claw which engages on the plate during the pressing process. The support claw suppresses a radial displacement of material. The extrusion die has a split projection (53) which divides the fastening element, which divides a radially outer portion during the pressing process by collar of the fastening element. #CMT# : #/CMT# An independent claim is included for a method for caulking a fastening element in a through hole of a plate. #CMT#USE : #/CMT# Device for caulking a fastening element, particularly metal screw in a through hole of a plate. #CMT#ADVANTAGE : #/CMT# The device has an extrusion die acting on a flange and a support claw which engages on the plate during the pressing process, where the support claw suppresses a radial displacement of material, and hence ensures improved and simple fixing of fastening element into thin sheets. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic sectional view of a caulking device. 1 : Screw 10 : Metal sheet 11 : Reinforcing element 51 : Extrusion die 53 : Split projection.
