Abstract

PURPOSE: To transfer a pattern easily to a thin plate by using small compressive load in transferring a pattern on a workpiece of thin plate by a die that has a punch and a pattern by utilizing high pressure of liquid.
CONSTITUTION: A liquid 10 such as water or oil is put in a space formed by a die 5-a and a knockout, and the external form part of a thin-plate workpiece 1-a of plastics, brass, nickel silver, aluminium is set in an internal-form guide part of a guide plate 9 fixed on kthe upper face of the die 5-a, and a clearance is made between it and inner diameter of the die 5-a. A punch 4-a provided with a pattern 4'-a on the lower face is lowered to draw the workpiece 1-a, and the workpiece 1-a is held between the die 5-a and punch 4-a to form a closed state. Further, the punch 4-a is lowered to increase the liquid pressure, and after transferring the pattern 4'-a on the lower face of the punch 4-a to the work 1-a, the exerrnal form is press-blanked, and a product such as a dial plate is manufactured.
