FORGED JOINING MACHINE

Abstract

A new forging joining machine is described that enables a solid-state joining at a relatively low temperature and in a short time, while generating a plastic flow in a joining interface.The forging joining machine comprises: a support device that supports a bottom surface of a joining section of elements to be joined in a state in which the elements are stacked on top of each other; a pressure device that exerts pressure on a top surface of the joining section in the state in which the elements are stacked on top of each other; a stroke control device that controls a gap between the support device and the pressure device; and a heating device that increases the temperature of a corresponding section of the joining section to a predetermined temperature range by coming into direct or indirect contact with a corresponding section of the elements, wherein the stroke control device controls a reduction ratio R (T0 / T1) that represents a ratio of a thickness T0 of the joining section before joining to a thickness T1 of the joining section after joining.
