A tool rig for the compaction of particulate materials includes a base and a cylinder block disposed on the base. At least two pistons are disposed within the cylinder block and one piston is at least partially disposed within one other piston. A supply component is disposed in the inner diameter of at least one of the pistons and defines at least one channel. The channel connects an energy supply to at least one of the pistons.

Tool rig for the compaction of particulate material

Compacted-powder opposed twin-helical gears and method

A toolset for forming a component from a powdered metal charge includes a die having two zones on the sidewall. Lubricant is applied to one of the zones. The powdered metal charge is initially compressed to an intermediate density and the lubricated zone of the sidewall brought into contact with the partially compressed charge. The charge is then further compressed to a final density.

Lubricated die

This invention relates to a device to compact parts with an undercut out of powder material having an upper die moveable relative a lower die, at least one upper punch associated with the upper die for relative movement therebetween, at least two lower punches associated with the lower die for relative movement therebetween, the lower punches defining a lower cavity with the lower die for filling with the powder material when the dies are in an open position, the upper die contacting the lower die in a closed position for movement of one of the lower punches towards the upper die so as to transfer the powder material towards the upper die and then to compact the powder material between the upper and lower punches with said dies in the closed position so as to produce the part; the dies moveable to an eject position for ejection of the compacted part.

Undercut split die

This invention relates to a device to compact parts with an undercut out of powder metal, including a pair of dies linearly moveable relative to one another and then phased, and an associated linearly displaceable pair of punches to produce said parts with said undercut.
