Abstract

PURPOSE: To enable the work to be precisely shaped by beforehand forming the recess of the work to be finish molded by pressing to a shape resembling to said recess by a removing method.
CONSTITUTION: When the work 6 which has beforehand been formed to a shape of a recess resembling to a desired shape by a known method such as, for example, machining, etching or beam working, is pressed by means of a stationary die 2 and a driving die 3, the draft of the material in the lower part of the driving die 3 mainly assumes the direction of an arrow and the edge 6a of the recess is shaped with virtually no deformation. In addition, if the work 7 which has beforehand been formed with a recess is press-finished by means of a female stationary die 4 and a male driving die 5, the material in the lower part of the die 5 is extruded in the direction of an arrow and the edge 7a of the recess is shaped with virtually no deformation.
