Problems solved by technology

But the shortcoming of the method described in the US-B1 document or the female mold tool is that: due to the design of an intermediate cavity between each female template, the stability and wear resistance of the female mold tool are relatively small, thus making the Forming / deformation forces that can be accommodated by the female tool are significantly limited and the achievable surface compaction is not sufficient for some applications

Abstract

The invention relates to a tool for compacting the surface of a powder-metallurgically produced component (2), comprising a female die (1) and a male die (20), a clearance (5) which extends from a first female die opening (6) to a second female die opening (8) being arranged in the female die (1) and having a wall surface (10) for bearing against the component (2), and the male die (20) having a male die length (23) and a male die surface (21), wherein an inside diameter (12) of the clearance (5) in the female die (1) becomes smaller from the first female die opening (6) in the direction of the second female die opening (8) or an outside diameter (22) of the male die (20) becomes greater over the male die length (23), and wherein a compacting element (17) is arranged on the wall surface (10) of the female die (1) or on the male die surface (21). The compacting element (17) is formed with a thread-like profile.

Description

technical field [0001] The invention relates to a tool for compacting the surface of a component made by powder metallurgy, comprising a female mold and a male mold, wherein a void is provided in the female mold, and the void is formed from a first female mold The die opening extends to the second female die opening and the void has a wall surface in contact with the component, the male die has a male die length and a male die surface, and the inner diameter of the void portion of the female die extends from the first female die port toward The opening of the second female die becomes smaller, or the outer diameter of the male die becomes larger in the length of the male die, and a compacting element is arranged on the wall of the female die or on the surface of the male die; the present invention It also relates to a method for compacting the surface of a component manufactured by powder metallurgy by means of a tool having a die and a die, wherein the die is moved through th...
