Abstract

In order to be able to forge round and sharp-edged bars down to very small dimensions without a tool change on a longitudinal forging machine, pivotable guide levers 18 for guiding rams 9 bearing tools 10 to 13 are provided with additional tools 14 to 17 which can be actuated in common with the tools 10 to 13 on the rams when the guide levers 18 are freely movable and the rams 9 are positively locked within the guide levers. When the guide levers 18 are fixed on the machine frame 6 and the rams 9 are guided in a straight line, previously round rough-forged material can be given sharp edges in a finish-forging operation, the mutually opposite pairs of tools 10, 12 and 11, 13 on the rams acting like two hammer-forging presses arranged in different vertical planes. <IMAGE>
