Abstract
A die having adequate flexibility at an entirety thereof while maintaining rigidity of a design surface is presented. A die is a die for a machine press. The die is a die for pressing a work plate together with a contraposed die and forming the work plate into a target shape. The die is provided with a design block, a positioning block, and a plurality of rods. The design block has a design surface for transferring the target shape to the work plate. The positioning block is used for positioning the die relative to the contraposed die. The design block and the positioning block are connected by the plurality of rods.
Claims8
A pair of dies for a machine press, the pair of dies being contraposed to each other and configured to press a work plate and to form the work plate into a target shape, each die of the pair of dies comprising:
- a design block having a design surface configured to transfer a target shape to the work plate by sandwiching the work plate with a design block of the counterpart die;
- and
- a positioning block configured to directly engage with a positioning block of the counterpart die for positioning the die relative to the contraposed die;
- wherein the design block and the positioning block are spaced apart from each other, the design block is supported only by a plurality of rods, the design block being connected to the positioning block by rods in the plurality of rods, and the plurality of rods have a flexibility such that the design block moves with respect to the positioning block.
