Abstract:
A method of assembling a rectangular tube to a member having an angled exterior surface, said method comprising the steps of:(a) providing a cam trim die having a pair of drivers, a pair of slide cams, and a pair of filler cams, each of said slide cams having a cutting section, each of said filler cams having a sheering support;(b) positioning the rectangular tube in said cam trim die such that said sheering supports are positioned substantially outside said rectangular tube adjacent opposing sides of said rectangular tube and said cutting steels are positioned substantially within said rectangular tube adjacent said opposing sides;(c) moving said drivers such that said drivers engage said filler cams and inwardly drive said sheering supports toward said opposing sides of said rectangular tube and simultaneously engage said slide cams and outwardly drive said cutting sections to produce a shearing effect between said sheering supports and said cutting sections to form angled trim lines on said opposing sides of the rectangular tube;(d) mating said angled trim lines of said rectangular tube with said angled exterior surface of said member; and(e) securing said angled trim lines to said angled exterior surface.
