Claims

[Claims for Utility Model Registration] Pressure on a shaft material for manufacturing a shaft member in which an arbitrary number of powder compacts are directly molded and fixed in an arbitrary position in an arbitrary phase. A device for directly forming and fixing powder compacts, which is installed at or below the shaft material insertion hole provided perpendicular to the center, and connected to a vertical drive device that allows the shaft member to move up and down. The shaft mounting member is placed and fixed around the shaft by a rotary drive device such as a pulse motor on a rotary plate which is rotatable over the lower mold holder via a thrust roller bearing, and To adapt the compacted body of the shaft material to the part where it is to be directly molded and fixed, and to fill the space between the part that grips the shaft material and the shaft material in the mold matching state with metal powder raw material for powder metallurgy. A molding die having a vertically divided structure in which a cylindrical cavity with a bottom is defined, and a shaft member on which a powder compact is directly molded and fixed is vertically movable in the vertically divided state; The powder compact is directly molded and fixed in the upper punch, which rotates synchronously or integrally with the vertically split structure forming die, and the lower die holder, which is disposed below the vertically split structure forming die. 1. An apparatus for directly forming and fixing a compacted powder onto a shaft member, characterized by having a shaft member insertion space into which a shaft member can be loosely inserted.
