Patent attributes
The invention concerns a method whereby components are arranged in a mounting device, outside an internal high-pressure forming press, in accordance with their position and their function, such that they are linked to one another. The mounting device comprises an upper part and a lower part including cavities identical to the cavities of the internal high pressure tool. Once the components have been installed, the mounting device is introduced in the internal high-pressure press, then the upper part or the lower part of the mounting device is withdrawn, the part of the mounting device remaining in the internal high-pressure press being displaced against the upper tool or the lower tool. For the forming process, the components are maintained in a part of the tool by depression or by clamping, then the part of the mounting device is removed from the internal high-pressure press, thereby ensuring high precision positioning of components. Additionally, the production rate is substantially increased. The invention is particularly applicable for the production of cam shafts.
