Abstract

PURPOSE: To obtain a simple inspecton method with an appreciating function by bending the circumference of a tested steel sheet after cramping it by a cylindrical rumple press tool and then by forming it in a container by a punch.
CONSTITUTION: Galvanized steel sheet 3, test bar, is placed on lower mold (dice) 2 and cramped and bent by cylindrical rumple press tool 6 to obtain state 3', and a clyindrical shape is formed by punch 5. Then, the state of the galvanization of the flank of the container-shaped cylinder obtained here is observed to test it breakaway. Angle (θ) of 45W75° of lower mold dice 2 is adequate. This method, checking the breakaway of plating metal when its flank moves in pressure contact by dice angle part 7 of dice 2, is simple and excellent in appreciating function.
