Abstract

PURPOSE: To easily manufacture flat keys under excellent productivity by only one process of press working, by making a pair of female molds conforming to the flat key, and putting the material into the molds, and shaping it under pressure.
CONSTITUTION: A material 3 is put between a die 1 and a punch 2 which construct a female mold conforming to a flat key, and the material is pressed with the die 1 and the punch 2. When the material is pushed by the projected part of the punch 2, excess metal is forced out as shown by (a). Then this pressed product is cut at lines C-C' and D-D' and the excess metal is removed. Thus a flat key is manufactured. As mentioned above, by only one time press working, flat keys can easily be manufactured inexpensively and under excellent productivity.
