Abstract (en)
The heating of a forging machine tool, with an insert carrier (11, 13) and an insert (1, 3) with forging imprint on a free face, in preparation for a forging operation is achieved by arranging a furnace element (20) on the insert carrier. The furnace element has a burner (30) and a chimney for the evacuation of gas, forming with the face of the insert a heating enclosure. The enclosure is heated until the insert attains a determined temperature and the furnace element is then retracted. Independent claims are also included for : (A) a removable furnace element used in this method of heating a forging machine tool; (B) a removable heating assembly incorporating the removable furnace element.
