Apparatus for manufacturing metal articles, in particular of light alloy
First Claim
1. An apparatus for die forming metal articles from a molten metal said apparatus including a first die portion and at least a second die portion which are moveable relative to one another between an open condition and a closed condition, said die portions, in a closed condition, delimiting die cavities which define a shape of one or more articles to be formed, the apparatus further comprising a furnace arranged below and connected to the die by a feeding duct, to heat a metal to its molten state and to control a flow of the molten metal through the feeding duct to hollow impressions formed as part of the first or the second portion of the die, said apparatus further comprising a moveable punch located in each hollow impression, which punch is movable towards the other portion of the die, and is adapted to apply a predetermined pressure on the metal article being formed, wherein each punch is moveable independently from all other punches, said apparatus further comprising a controller for controlling a pressure applied by each punch and for levelling the pressure applied by all the punches on the article being formed.

Abstract
An apparatus for manufacturing metal articles, in particular of light, alloy, includes a die including a pair of portions which can be separated to each other, which, in the closed condition, delimitate forging cavities having a shape corresponding to one or more articles to be forged, and a furnace adapted to melt the metal and to control the reaching by the molten metal of the hollow impressions of the die, as a result of overflowing through a duct connected to the furnace. A portion of the die includes, for each hollow impression, a movable punch adapted to apply a predetermined pressure on the relevant article during the forging step. Each punch is moveable in a manner independent from the other punches, and the apparatus includes a controller for controlling the pressure applied by each punch during the forging step, which allow to level the pressure applied by all the punches on the relevant article.
