Title:
DIE FOR UNIFORMLY PRESSING SIDE FACE OF MATERIAL TO BE WORKED, ARTIFICIAL BONE MADE OF TITANIUM OR TITANIUM ALLOY HAVING HIGH BIO-COMPATIBILITY
Document Type and Number:
Japanese Patent JP3513587
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an artificial bone made of titanium or titanium alloy on the surface of which bio-compatibility is imparted to utilize for a die for pressing a material to be worked, artificial hip-joint stem or the like.
SOLUTION: This die is a die having segmental dies between which the material to be worked is put are oppositely arranged and an outer frame situated on the outer periphery of the dies. By making the outer frame and segmental dies functions as a wedge and sliding motion execute, load with a vertical single axis press device is converted into loads from both directions which are horizontally opposed. Then, by moving the segmental dies so as to clamp the material to be worked made of titanium or titanium alloy and uniformly pressing the side faces, and, by executing hot pressing using a die for imparting a necessary shape to the material to be worked, the artificial bone is obtained by imparting the necessary shape to the material to be worked and simultaneously press-fitting living body active ceramic particles such as apatite hydroxide on the surface.
