A method for manufacturing a scion of a blind rivet.

摘要

A metal rod HAVING A LIMB CUT conical or pyramidal used to make a mandrel (21) of a rivet SHUTTER. The rod is held in place between a pair of SWEEP SEGMENTS (11) to one end of a predetermined length including cutting LIMB AND EMBED protrudes from the upper surface (14) of the segments (11). Then the BUTT FLUSH (26) is axially compressed to form a head CHUCK (27) by means of a nail (12) having a lower face (17) extending parallel to the top surface (14) of the SEGMENTS (11) and a hollow conical or pyramidal (18) ADJUSTABLE CUTTING ON LIMB. ASI, AN INTERMEDIATE PART FREE BUTT FLUSH (26) compressed by the dumper (12) is radially expanded to form the head (27) having a flat flange (31) from which the tip CUT (20A) protrudes VERTICAL AND medially and a pin (32). The mandrel (21), whose head UNIFORMLY FORMED WITHOUT SHAFT Eccentricity AROUND A BODY CHUCK, MAY RESULT ASI in an economical manner using a manufacturing apparatus NAILS.
