Abstract
A sintering assembly includes a mold defining a cavity. The sintering assembly further includes at least one ram configured to extend into the cavity. The sintering assembly also includes a negative punch disposed in the cavity and a positive punch disposed in the cavity. The positive punch includes at least two segments, each segment of the at least two segments comprising a ram interface configured to abut against the at least one ram. Related methods and sintering punches are also disclosed.
Claims20
A sintering assembly comprising:
- a mold defining a cavity;
- at least one ram configured to extend into the cavity;
- a negative punch disposed in the cavity;
- and
- a positive punch disposed in the cavity, the positive punch comprising at least two segments, each segment of the at least two segments comprising a ram interface configured to abut against the at least one ram.
2 more elements
A method comprising:
- disposing a first punch into a cavity of a mold, the first punch comprising one or more segments;
- depositing a base material over the first punch in the cavity of the mold;
- disposing a second punch over the base material in the cavity of the mold, the second punch comprising one or more segments;
- applying a pressure to the base material between the first punch and the second punch;
- applying heat to the base material between the first punch and the second punch until the base material forms a solid structure;
- removing the first punch from the solid structure by separating one segment of the first punch from another segment of the first punch;
- and
- removing the second punch from the solid structure by separating a first segment of the second punch from a second segment of the second punch.
5 more elements
A sintering punch comprising:
- a base;
- a semispherical surface on an opposite axial end of the sintering punch from the base;
- an intermediate segment forming an intermediate portion of the base and an intermediate portion of the semispherical surface;
- at least two outer segments forming outer portions of the base and outer portions of the semispherical surface, the intermediate segment configured to be removed axially relative to the at least two outer segments;
- and
- an interface between the intermediate segment and at least one of the at least two outer segments, the interface angled such that the intermediate segment has a first width at the base that is greater than a second width of the intermediate segment at the semispherical surface.
