A device for the spinning of pieces in the press on the basis of an ingot

摘要

P the invention relates to a device for the spinning of the parts to the press, from an ingot, in particular of an ingot of light metal such as aluminum, by means of a forming tool to a container, which is mounted a tool for working by chip removal of the scaling of the oxide layer covering the ingot. The tool works by the removal of chips is composed of several blades or similar members of the crust, which can move radially with respect to the direction of extrusion and bent so as to be completed with each other and form a ring of the crust which is adjustable and removable covering the ingot. A pressure plate whose diameter is less than that of the ingot limits the travel of the ring of the crust towards its end. / p
