Abstract

The invention relates to a method for fixing a forging mould and a clamping part of a forging hammer on a casing of a forging machine to lead to revolution of a rolling column. The invention has an effect that a reversing force cannot be transmitted to wires to be processed, and under a static state a shaping process is carried out along hole-shape of the forging mould. Moreover, the replacement of the forging mould and the forging hammer can be carried out while the forging mould and the forging hammer are still arranged in the clamping part, thus the replacement is extremely simple and the operation efficiency can be enhanced. And the clamping part of the rolling column also can be used as a flywheel, which leads to a miniaturization of the whole part and simultaneously eliminates the twisting of a reversing shaft when the flywheel is additionally arranged.
