ABSTRACT:
This present invention concerns a process for the heating of a forging machine tool, including an insert holder and an insert with one free face bearing a forging impression, in preparation for a forging operation in the said forging machine. The process is characterised by the fact that the insert holder includes a furnace element that has at least one burner and one flue for removal of the gases, forming, with the said face of the insert, a closed heating chamber, the said chamber being heated until the insert reaches a given temperature, when the furnace element is removed.The invention also covers the forging tool, including an insert with an impression, mounted in an insert holder, for implementation of the process, and a removable furnace element.
