FORMING ROLL OF PLATE-LIKE BAR STOCK WITH FIN

摘要

PROBLEM TO BE SOLVED: To surely form a prescribed height fin while suppressing a work from preceding and width stretching even when the work is a plate-like bar stock of copper having rich ductility in a forming roll to form a planar bar stock with fin. SOLUTION: In the forming roll of the plate-like bar stock with fin in which recessed grooves 3B... to form fins on the surface of the plate-like bar stock to be formed is formed on the outer peripheral face 3A of a roll body 1 rotating around an axial line O, the surface roughness of the outer peripheral face 3A of the roll body 1 is set in a range of Ra 0.1-1.6.
