In particular, the stem extrusion die has 3 to 8 layers in total.
In particular, the boss is just clamped in the groove of the upper layer of outer die when the outer die is assembled.
In particular, the grooves can just catch the boss of the next outer die when the outer die is assembled.
Compared with the prior art, the utility model has the following beneficial effects:
the isothermal extrusion die with the layered structure adopts a layered structure, each layer is divided into an inner die and an outer die, and when the section of the rod part of the long-shaft forging is changed, only the inner die of the corresponding rod part extrusion die needs to be replaced. And the die is very simple to manufacture and assemble, and the working efficiency is greatly improved.
