Claims

[Scope of utility model registration request]

It has a punch with a blank holder arranged around its outer periphery, and a die that can move toward and away from these punches, and the blank holder and die are used to draw the workpiece of the blank. In a press die that clamps the outer circumferential portion and draws the processed portion of the blank in cooperation with a die and a punch, the blank holder includes a clamping member that directly supports the blank and a support that supports the clamping member. The clamping member is divided into at least a first and a second portion, and is supported by the support member via first and second biasing members, respectively, and the first and second biasing members The members are configured to apply different pressing forces to the corresponding first and second portions, and the first portion supported by the first biasing member with the smaller pressing force is The structure of a press die is characterized in that it is located on the side where deep drawing is performed on the outer periphery of the workpiece part of the blank, or on the side where the clamping area is wide.
