The present invention relates to a metal powder compression tool for forming compacts for sintering, including a first punch ( ) adapted to compress powder located in a die ( ). The clearance between the punch and the die is greater than the radial expansion of the punch under the desired compression effort, and lower than the mean size of the powder grain.

Metal powder compression tool

A device for holding sintered cams during their binding on a tube by expansion of the tube, including, for each cam, two blocks intended for enclosing the cam in housings complementary to the cam contour. The dimensions of the housings are chosen so that the play between the housings and the largest cam within a predetermined tolerance range is as close to zero as possible by excess, the two blocks being provided to bear against each other whatever the dimensions of the cam within the tolerance range.

Means for fixing a connecting fitting on a sintered metallic filtering

A process for fitting at least one metal piece, which has at least one cylindrical bore, around a metal tube, in particular a metal cam shaft, as used, for example, in an internal combustion engine. The process includes clamping the metal piece in the assembly unit and introducing the metal tube into the bore of the metal tube with one end of the tube bearing upon the retractable stop. After expansion of the tube to fix the one metal piece on the tube, and the retractable stop is retracted before any additional metal pieces are fitted to the tube.

The invention relates to a method of producing connected sintered articles obtained by breaking a unitary preform. It is characterized in that:
